Product details

Board-to-Cable/Wire Header with Locking Ramp

Pitch, Plating, and Temperature Range

The 0.250" (6.35mm) pitch is the key dimension for the board footprint — it also sets the spacing between adjacent contacts, which limits the voltage rating and crosstalk at higher frequencies.

Against the 1376775-2 (5-position, 2.54mm pitch, 3 A, 250 VAC, tin post, 8µin gold mating), the 640901-3 has a wider 6.35mm pitch and thicker 30µin gold mating finish. The wider pitch means a larger board footprint but also higher current capability per contact — the 640901-3 is better suited for power distribution where the 1376775-2 is a signal-only part.

Frequently asked questions

What is the mating connector for 640901-3?

The mating half is a Universal MATE-N-LOK plug housing with female crimp terminals. The 6.35mm pitch and locking ramp are specific to the series — confirm the circuit count and keying before ordering.

Is 640901-3 RoHS compliant?

Yes, it is ROHS3 Compliant per the manufacturer's listing.

Can 640901-3 be used with 0.250 inch tab connectors?

The 0.250" (6.35mm) pitch is the centerline spacing between contacts, not the tab width. The mating interface uses a female socket contact — it mates with a male pin from the plug housing, not a tab. Verify the contact type before ordering.
