Product Overview

A right-angle header gets specified when the height budget runs out and the harness has to leave the board sideways. Three things then decide whether the part survives production: where the mating load goes, whether the housing takes a lead-free oven without blistering, and whether the terminals carry your current without cooking the insulation.

CONSHARE builds this 3.00 mm pitch dual-row wafer in seven sizes, 2 x 2P through 2 x 8P, on a black halogen-free PA9T body with high-conductivity copper terminals in matte tin over nickel. All seven ship on tape and reel.

The Board Lock Is Doing Three Jobs

A sideways harness is a lever

On a vertical header an unmating pull runs up the pin axis into the board. Turn the header 90 degrees and that pull becomes a prying moment on the rear row of joints, spread across the full body width. Joints that pass bench testing start cracking after a few service visits. The board locks move that moment into the laminate.

Pick your hole size on purpose

Board hole is 2.41 mm if you want the lock to bite, or 3.00 mm if operators should seat the part by hand. The first suits automated insertion; the second suits hand-build and rework.

The same fitting is your ground path

Those end fittings are metal, configured as soldering lugs as well as retention hooks. You get a chassis or ground-plane tie at each end with no extra stake or second component. On a motor drive or switched supply that path matters for ESD and common-mode noise.

What Each Size Will Actually Carry

Current depends on circuit count and wire gauge

Heat builds across the housing, so one terminal is rated lower at sixteen circuits than at four. The wire matters equally, because the crimp and wire usually set the limit, not the header:

Derating is cumulative with ambient.

Copper against brass, and the number that matters in year five

The alternative build for this footprint uses brass terminals, and at the same wire size it carries roughly 5.0 to 6.5 A per circuit where copper carries 8.5 to 12.0 A. That is 60 to 90 per cent more current in the same 3.00 mm body, and the reason is thermal: copper moves heat out of the contact interface faster, so the assembly runs cooler at a given load.

Contact resistance is 10 milliohms as supplied, 20 milliohms after environmental conditioning; design to the second. Working rating is 500 V AC or DC with 1,500 V AC withstand, which on a mains-referenced board removes the creepage slots a finer pitch would need.

PA9T Buys You a Process, Not Just a Rating

No pre-bake, no popping

Nylon 6/6 absorbs enough moisture that a bag left open over a weekend can blister in reflow. PA9T does not, so these housings go from bag to oven with no drying cycle. One less step, one less way to scrap a batch.

One oven pass instead of two

Because the ends carry soldering lugs and the body takes lead-free reflow temperature, this header runs as an intrusive reflow (pin-in-paste) part alongside SMT components. A board that would otherwise need a selective or wave pass for one connector loses that step.

Where PA9T is not the answer

Operating range is -40 °C to +85 °C: industrial panels, indoor supplies, instrumentation, most appliance cavities. Not a sealed enclosure beside a heatsink, not under-hood. Above 85 °C, ask for the LCP build.

Choosing One of the Seven Sizes

Body length grows 3.00 mm per added position.

Check the tape width before you check the price

Three widths appear across the range: 24 mm for the 2 x 2P, 32 mm for 2 x 3P through 2 x 5P, 44 mm from 2 x 6P up. Feeders that only carry 24 mm tape will not run the six larger sizes.

Where each count tends to land

Four and six circuits show up on RGB and RGBW LED modules, channel plus return pairs, and compact sensor pods. Eight and ten cover PLC expansion blocks and multi-axis stepper drivers, where signal, power and shield share one housing. Twelve to sixteen go to display interfaces and internal power distribution. Where two connectors would sit side by side, one larger wafer usually wins on assembly time and harness cost.

Fitting It to Your Board and Your Line

Tail length against board thickness

Tails are 3.2 mm. On a 1.6 mm board that leaves about 1.6 mm protruding on the solder side, where wave solder throws a full fillet without a touch-up iron. On a 2.4 mm board, common on power stages, protrusion drops to roughly 0.8 mm: the joint forms, but the fillet thins and rejections climb. Thicker boards get a longer tail on the same body.

What the reel has to do

Two hundred pieces per reel, twelve empty pockets at the leader and thirteen at the tail, cover tape peel strength held between 20 and 120 grams, sprocket pitch cumulative tolerance within 0.2 mm over ten pitches. Those numbers keep a feeder indexing. Cartons run 1,800 pieces at 2 x 2P down to 1,000 at the larger sizes, each with a lot code traceable to its plating batch.

When to Choose Something Else

Honest boundaries save time. Look elsewhere if your ambient exceeds 85 °C, in which case ask for the LCP build; if you need more than sixteen circuits, since 2 x 9P through 2 x 12P exist on request but two connectors often serve the layout better; or if you need a surface-mount footprint, this being a through-hole part. Sustained vibration above roughly 10 g wants a positive-latch receptacle.

How CONSHARE Builds and Checks These

Checkpoints between strip and sealed reel

Tin and nickel thickness are verified per plating lot against the 100 and 40 microinch minimums, not assumed from the bath. Housings are checked for body length and pitch on first-piece and patrol inspection, terminal retention is pull-tested, and contact resistance is sampled from finished reels rather than loose parts.

Samples, lead time and what we build to order

Standard sizes are held in stock. Samples ship within three working days of confirmation, production reels typically in two to three weeks. Built to order on the same body and tooling:

• Tail length from 1.6 mm to 3.3 mm

• Plating in bright tin, matte tin, or gold from flash to 30 microinches

• Board lock length and span, or omitted entirely

• Soldering lug, grounding lug, or plain retention hook

• Tray packing instead of tape and reel, and any pin count from 2 x 1P to 2 x 12P

Tooling-only changes are faster than new mould inserts.

Questions Before the First Order

Will the housing survive our reflow profile?

Yes, up to a standard lead-free peak, and PA9T is chosen partly so you can skip the pre-bake. Send the profile if it runs hot or long.

Can I get these on 24 mm tape?

Only the 2 x 2P. Everything from 2 x 3P upward needs 32 mm or 44 mm.

What changes if I drop to the brass terminal version?

Same body, same dimensions, roughly 40 to 45 per cent less current per circuit at the same wire size. Fine for signal, not fine for power.

Do you sell cut tape, and can you match an existing footprint?

Yes to cut tape, and tell us your board thickness so the sample arrives with a usable tail length. For footprint checks, send the drawing or the part you are replacing: most 3.00 mm dual-row right-angle layouts are interchangeable, but board lock hole positions are the usual exception.
