Card Edge Connector
Industrial, IT Datacom
Every hardware designer knows the frustration of specifying a connector that looks good on paper but fails on the production line. Whether it's solder joint inconsistencies, housing warpage during reflow, or contact resistance drifting after temperature cycling—these small components can become your biggest production bottlenecks.
At CONSHARE, we engineered this 2x3 pin gold finger DIP connector specifically for designers who need predictable performance without over-engineering. The 2.54mm pitch standard keeps your layout familiar, while the selective plating and high-temperature housing address the real failure modes that cause field returns and production scrap.
Why does the 180° orientation matter more than you think? Because vertical through-hole mounting means your pick-and-place machine can handle this connector alongside your other through-hole components in a single pass. No secondary operations, no hand soldering, no reorientation fixtures.
The straight pin alignment also means better solder joint visual inspection—every joint is visible from the same angle, reducing QC time and missed defects. For high-mix, low-to-medium volume production, this translates directly to lower assembly cost per board.
The dual-row 3-pin layout (6 contacts total) strikes a practical balance that many designers overlook. It's enough pins for:
A small power rail (+V, GND, +V sense)
Basic control signals (SDA, SCL, interrupt)
A compact sensor interface
But not so many pins that you're paying for unused contacts or wasting board real estate. This 2x3 footprint is particularly popular for:
Daughterboard power interfaces
Sensor module connections
Configuration jumpers with status feedback
Small display panel hookups
"Half gold tin" isn't a compromise—it's an optimization. Here's the engineering logic:
The gold-plated contact zone (1 micro-inch) handles the mating interface. Gold provides:
Stable contact resistance across temperature cycles
Excellent corrosion resistance for humid or industrial environments
Consistent insertion force over multiple mating cycles
The tin-plated solder tail is where the connector meets your PCB. Tin offers:
Superior solder wetting compared to gold
No risk of gold embrittlement in the solder joint
Lower material cost where it doesn't affect performance
This selective approach means you get gold's reliability exactly where you need it—at the contact interface—without paying for gold plating on the solder tails where it would actually be a liability.
One micro-inch of gold isn't the thickest plating available, and that's intentional. For the vast majority of commercial and industrial applications with mating cycles under 100, 1u" gold provides:
More than enough corrosion protection
Stable contact resistance throughout the product lifecycle
Cost efficiency that adds up across thousands of units
If your application requires 500+ mating cycles or operates in extreme corrosive environments, talk to our engineering team about heavy gold options—but for 90% of board-to-board and internal connection needs, 1u" selective gold is the right balance.
The black high-temperature housing isn't just about aesthetics. It's formulated to withstand:
Standard reflow soldering profiles without warping or blistering
Peak temperatures up to 260°C for short durations
UV exposure without discoloration or brittleness
This matters because housing dimensional stability directly affects contact alignment. A warped connector means misaligned pins, uneven insertion force, and potential contact reliability issues down the line. CONSHARE's high-temperature material maintains its form factor through your entire assembly process, so what you see in the datasheet is what you get on your production line.
The 0.5mm contact slot width is engineered for a specific gold finger thickness range, ensuring:
Normal contact force within specification
No excessive insertion force that could damage the gold finger
No loose fit that would cause intermittent connections
This precision slot dimension means your assembly technicians or end-users get a consistent feel every time—no "sometimes it works, sometimes it doesn't" variability that plagues cheaper connectors with looser tolerances.
Not sure if this 2x3 pin configuration is right for your design? Use this quick reference:
Application Type | Pin Count Adequacy | Typical Use Case | CONSHARE Recommendation |
|---|---|---|---|
Simple power connection | Perfect fit | +5V, GND, sense line | Ideal choice |
I2C / SMBus interface | Perfect fit | SDA, SCL, GND, power, 2 spares | Ideal choice |
Small sensor module | Perfect fit | Power, ground, 2-3 signal lines | Ideal choice |
Configuration header | Perfect fit | Jumpers with status feedback | Ideal choice |
8-bit data bus | Insufficient | Parallel data transfer | Consider 2x5 or 2x7 pin |
High-current power (>3A) | Limited capacity | Multiple pins in parallel | Consult engineering |
High-vibration environment | Good fit | Industrial controls | Add locking option |
1. How many signals do you actually need?
Count your required connections—power, ground, signals, spares. If the answer is 4-6, the 2x3 configuration is your most space-efficient option. If you need 8+, step up to a wider pin count.
2. Is board space at a premium?
The 2x3 footprint occupies minimal real estate while still providing dual-row reliability. For compact designs—wearables, small sensor nodes, portable test equipment—this is often the sweet spot between functionality and size.
3. Will this be mated frequently?
If it's a set-and-forget internal connection (most applications), the 1u" selective gold plating is perfect. If it's a user-accessible port with daily mating, consider our heavy-gold variant.
Over-specifying pin count: More pins = more cost + more board space. Only specify what you need plus 1-2 spares.
Ignoring the housing material: Cheap connectors use standard-temperature plastic that warps in reflow. Always verify the housing is rated for your soldering process.
Assuming all gold plating is equal: Selective gold (gold on contact only) is different from full gold plating. Know which part of the connector is actually gold-plated.
A Midwest industrial controls manufacturer was experiencing 3-5% field failure rates with their previous connector supplier. The failures traced back to two issues:
Housing warpage during wave soldering causing misaligned pins
Corrosion-related contact resistance drift in humid factory environments
After switching to CONSHARE's high-temperature black housing connectors with selective gold plating:
Field failure rate dropped to 0.3% over 12 months
Solder joint inspection pass rate improved by 12%
No corrosion-related failures reported in 18+ months of field data
The 2x3 pin configuration was used across their temperature and humidity sensor modules, providing power and I2C communication in a compact footprint.

A: Yes. The high-temperature black housing is formulated to withstand standard reflow profiles without warping or blistering. We recommend following standard through-hole reflow guidelines.
A: For most commercial and industrial applications with fewer than 100 mating cycles over the product lifetime, yes. If you need higher mating cycles or operate in extremely corrosive environments, contact us about heavy gold plating options.
A: Half gold tin (selective plating) means only the contact mating area is gold-plated, while the solder tails are tin-plated. This is actually preferable for through-hole applications because tin solders better than gold, and gold in the solder joint can cause embrittlement. Full gold plating is typically only needed for edge-card or surface-mount applications where the entire contact is exposed.
