14-Position Dual-Row Receptacle at 1.27 mm Pitch
The 20021311-00014T4LF: This is a 14-position, dual-row female socket header from the Minitek127® 1.27mm series, designed for board-to-board stacking. Through-hole mounting with a 0.094" (2.40 mm) post length provides a robust solder joint for the dual-row layout. The push-pull fastening means it mates without a locking latch — suitable for internal board stacks where vibration is moderate and the connector is accessed during service.
The receptacle mates with a matching 1.27 mm pitch pin header. The 0.173" (4.40 mm) insulation height, combined with the header's mated stack height, determines the z-height budget between parallel boards — a critical dimension for mezzanine card spacing. The dual-row arrangement with 0.050" row spacing keeps the connector width under 0.3" — narrow enough for tight board-edge layouts.
Operating Range and Material Ratings
The UL94 V-0 housing meets flame-retardant requirements for equipment inside a panel or cabinet. The insulator is black plastic, and the contact base metal is phosphor bronze — a standard spring alloy that resists stress relaxation at the upper end of the temperature range.
