Product details

26-Position Right-Angle Header at 3.50 mm Pitch

It uses a 0.138" (3.50mm) mating pitch with a 0.205" (5.20mm) row spacing, giving you a compact but serviceable footprint for routing traces between rows.

Through-Hole Right-Angle Termination for Board-Edge Routing

This is a through-hole, right-angle mount header. The contact length on the mating side is 0.280" (7.11mm) and the post length is 0.157" (4.00mm) — that post length is enough to clear a standard 1.6mm PCB and still leave a solid solder fillet on the bottom side.

Automotive and General-Purpose Duty with Active Production

The 175571-6 is listed for Automotive and General Purpose applications. The gray PBT insulation (Polybutylene Terephthalate) is a common choice for underhood connectors — it handles underhood temperatures and resists fuels and oils. Production status is Active. This part is RoHS compliant. Sourced per RFQ against your BOM quantity.

Frequently asked questions

What is the exact pitch of the 175571-6 header?

The mating pitch is 0.138" (3.50mm). The row spacing is 0.205" (5.20mm). That's a dual-row layout, so the overall footprint spans 26 positions across two rows.

Is the 175571-6 connector shrouded with a mounting flange?

Yes. It is fully shrouded on all four walls (Shrouded - 4 Wall) and includes a mounting flange. The flange lets you bolt the header to the panel or chassis for extra mechanical stability.

What is the current rating of TE 175571-6?

The current rating is listed as Varies by Wire Gauge. The header itself doesn't set a fixed current limit — the wire gauge you use in the mating terminal determines the ampacity. For a given wire size, check the terminal's derating curve.
