The 77313-422-44LF: The square male pins are through-hole soldered to the PCB.
Tin frets under repeated wipe — if the board sees quarterly field-service disconnects, a gold-plated sibling in the BERGSTIK® family is the more durable call.
A shrouded header adds polarisation and pin protection, but takes up more board area. The pitch, row count, and current rating are the same across both styles in the BERGSTIK® series.
The part number suffix LF indicates lead-free and RoHS-compliant manufacture per Amphenol ICC (FCI) standard practice.
