Product details

What This 2-Circuit Header Is

The 41791-0849: This is a Molex KK 156 header assembly — a 2-circuit, single-row pin header with a 3.96 mm pitch and a friction lock on the housing. The '30 S' in the description indicates a 30 µinch selective gold plating on the mating area, which gives it a solid cycle life for repeated connect-disconnect in a harness. The friction lock holds the mating receptacle in place against light vibration, but it's not a secondary lock — for high-vibration environments you'd want a TPA or a positive latch.

Frequently asked questions

What is the pin pitch of 41791-0849?

The pin pitch is 3.96 mm, which is the standard KK 156 spacing. This matches the board footprint for a 2-circuit header.

Is 41791-0849 RoHS compliant?

Yes, it is ROHS3 compliant, so it meets the latest EU RoHS directive for lead and other restricted substances.

What is the mating connector for 41791-0849?

It mates with a KK 156 2-circuit receptacle housing and the corresponding crimp terminals (e.g., Molex 2478 series). The friction lock engages with the receptacle's locking ramp.
