Product details

The 2-pin count makes it a natural fit for low-circuit power or signal links where a compact, keyed interface is needed.

Latch holder and shrouding — vibration resistance built in

The insulation height of 0.549" (13.94mm) gives clearance for the mating housing latch, so check your z-height budget if the board sits close to an enclosure wall.

No gold flash here — this is a cost-optimised signal/power header for production runs where cycle life is not the primary concern.

Frequently asked questions

What mates with Molex 2122100021?

This is a male pin header — it mates with a CP-3.3 series receptacle housing (sold separately) that accepts the matching crimp terminals. The latch holder on the header locks with the corresponding latch on the receptacle.
