Product details

Obsolete – sourcing reality for 77311-125-36

This BergStik header carries an Obsolete product status, meaning Amphenol ICC no longer produces it as a standard catalog item.

What this 36-position unshrouded header is

Pitch, footprint, and what mates with it

The 0.100" pitch matches the classic BergStik footprint, compatible with standard IDC receptacles, female socket headers, and crimp housings that accept 0.025" square pins.

Lifecycle and compliance details

Tin-lead post finish means this part is not RoHS compliant as shipped; if your BOM requires RoHS, look for a lead-free BergStik alternative with the same footprint. No official successor is listed; cross-referencing to a current BergStik header with the same 36 positions, single row, 0.100" pitch, and gold plating is the recommended path.
