What the 93690-103-04LF Is
Board Layout and Stack Height
The 0.100" (2.54 mm) insulation height and 0.505" (12.83 mm) overall contact length define the mated stack envelope. The 0.224" (5.70 mm) pin engagement length — the portion of the pin inside the receptacle when mated — means the header needs a minimum standoff from the board surface equal to the insulation height plus any intermediate board thickness in a mezzanine stack. The push-pull fastening type is a friction-latch mate — no screw or jack-screw — so the header is not suited for applications where vibration could back the mating half off. In a board-to-cable configuration the unshrouded pins are exposed to accidental shorting during handling before the mating connector is assembled.
Mating Compatibility and Termination
This is a male pin header — the mating half must be a matching BERGSTIK receptacle or any 0.100" pitch dual-row IDC, wire-to-board, or board-to-board female connector with square-pin compatibility. The square contact shape means the receptacle must accept a square post, not a round pin — round-socket军民 connectors will not seat correctly. The breakaway header design allows the strip to be broken to custom lengths in the field, so the 4-position base product can be sectioned down to fewer circuits if needed — but this specific listing is the fully-loaded 4-position configuration. The press-fit and solder dual-termination gives two board-attach options: press-fit for mechanical retention in a backplane, or solder for a conventional reflow/wave assembly.
Compliance and Flammability
The housing is rated UL94 V-0 — the highest UL94 flammability rating, indicating no flaming drips on a vertical burn test. This satisfies the flammability requirement for most industrial and commercial equipment enclosures.
