It uses the industry-standard 0.100" (2.54 mm) pitch and terminates via through-hole solder. The black UL94 V-0 housing and tin-plated phosphor bronze contacts are rated for 5 A per circuit at 110 V.
Plating and Duty Cycle
The 100.0 µin (2.54 µm) tin plating on the mating surface is thick enough for repeated insertion and removal in a production or test fixture, but tin-on-tin contacts have a lower mating cycle life than gold-plated alternatives.
No official cross-reference or successor is on record; the BergStik II series includes many position counts and plating options, so a direct pin-compatible substitute would need to match the 19 positions, 0.100" pitch, and unshrouded through-hole footprint exactly.
