Product details

In a board-to-board application where the header sees occasional rework or field replacement, that plating grade supports hundreds of cycles without exposing the base phosphor bronze. The gold-on-tin interface at the mating face avoids the tin-whisker risk of a tin-on-tin contact.

What Crosses into the Existing Harness

If you have a harness terminated with a 2-row, 18-position IDC socket or crimp housing, this header will likely fit the footprint. The push-pull retention means no latch alignment to worry about on site.

Frequently asked questions

What is the replacement for 77317-104-18?

A functional substitute would need the same 0.100" pitch, 2-row, 18-position unshrouded footprint — a board spin may be required if the original part is unavailable.
