The Molex 93939-122HLF is a 22-position, dual-row male header from the BERGSTIK II series, on the standard 0.100" (2.54 mm) pitch. It is an unshrouded, right-angle through-hole design with push-pull fastening — a general-purpose board-to-board interconnect for routing signals and low-current power along the PCB edge. The 22 positions are fully loaded, so the circuit count on the BOM matches the pin count directly. Rated 5 A per circuit at 110 V, the current capacity is typical for signal-level power and low-speed I/O — the limiting factor is the pin density at the board edge, not the contact itself. The 30.0 µ" (0.76 µm) gold plating on the mating surface is a robust grade for repeated mating cycles in a corrosive or field-service environment; the solder tails are tin for a reliable solder joint. The housing is rated UL94 V-0, the standard flame rating for equipment inside an enclosure. The insulation height of 0.190" (4.83 mm) and mating contact length of 0.160" (4.06 mm) define the board-to-board stack height when mated with a matching receptacle.
Mating and Termination
This unshrouded header mates with any standard 0.100" (2.54 mm) pitch dual-row receptacle housing — typically a BERGSTIK II or equivalent socket strip. The right-angle orientation routes the mating board or cable parallel to the PCB, which is the standard arrangement for board-edge interconnects in card-cage or mezzanine layouts. Termination is solder — the 0.120" (3.05 mm) post length fits a standard through-hole PCB. The square pins (0.025" square typical for this pitch class) provide a reliable solder joint and good retention in the plated through-hole before soldering.
Lifecycle and Sourcing
The 93939-122HLF carries an Active lifecycle status from the manufacturer — full production, no end-of-life notice. No official successor or cross-reference is on record.
