4-Position Dual-Row SMT Receptacle — 2.00 mm Pitch
The housing is black UL94 V-0 rated plastic, with a push-pull fastening type — no locking latch, so it relies on the mating header's retention features or a cable tie for vibration resistance.
This receptacle is surface-mount terminated with solder — no through-hole leads. The contact material is beryllium copper, which maintains spring force over temperature and repeated deflection — important for a socket contact that must grip the header pin reliably after reflow.
The part is RoHS Compliant.
The 91596 series includes 6-position (91596-106TRLF) and 8-position (91596-108TRLF) variants with identical pitch, plating, and ratings. A tube-packaged version (91596-104LF) exists with the same 4-position layout — choose the TRLF suffix for reel-fed assembly lines.
