Product details

12-Pin Shrouded Header with Locking Ramp

The 1-794631-2: Rated 250V with current capacity varying by wire gauge — the 3.00mm pitch and 0.118" row spacing set the board footprint and per-contact current ceiling.

Termination and Mounting Detail

Termination is listed as press-fit and solder — the through-hole posts (0.125" / 3.18mm long) can be press-fit into plated holes and then wave-soldered for a gas-tight joint. The insulation height of 0.364" (9.25mm) and black polyamide housing (UL94 V-0) suit it for densely populated boards where component clearance is tight. In a vibration-prone installation, the ramp alone keeps the mating receptacle seated; verify the mating half has a compatible latch feature.

Available through independent distribution channels. The base product number 794631 may help locate similar headers in the same series, but each position count and plating variant is a distinct order code.

The 3.00mm pitch and 0.118" row spacing are consistent across the series, so a 12-position, 2-row receptacle with the same pitch will mate mechanically. The male pin contacts (square, gold-plated) require the matching female crimp terminal from the Micro MATE-N-LOK terminal family. Wire gauge selection determines the current rating — the header itself does not limit current below the terminal's capability.

Frequently asked questions

Is 1-794631-2 obsolete, and what is the replacement?

Yes, 1-794631-2 is obsolete per TE Connectivity's lifecycle status. No official replacement part number has been assigned by the manufacturer. The Micro MATE-N-LOK series continues with other position counts, but a direct pin-compatible substitute for this 12-position, 2-row, 3.00mm pitch header is not documented. Sourcing is through independent channels — quantities confirmed at RFQ.

What is the mating connector for 1-794631-2?

The mating half is a Micro MATE-N-LOK receptacle housing with 12 positions in 2 rows at 3.00mm pitch, featuring a compatible locking ramp latch. The receptacle accepts the series' female crimp terminals — wire gauge selection determines the current rating.

Is 1-794631-2 RoHS compliant?

Verify compliance against your local RoHS requirements — the tin-lead plating is a legacy finish.
