The 0.100" pitch and 0.100" row spacing define the PCB footprint — a 50-position, 2-row header requires a 25-pin-per-row layout with 2.54 mm between centres. The 0.380" (9.65 mm) mating pin length provides ample entry depth for standard box headers or IDC receptacles. The 0.120" (3.05 mm) solder tail length suits a standard 1.6 mm thick PCB; for thicker boards, verify the post protrusion through the plated hole.
There is no official successor or cross-reference on record from the manufacturer.
The pin pitch is 0.100" (2.54 mm) on both the pin-to-pin spacing and the row-to-row spacing, a standard industry footprint.
The header is rated 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts.
The 86837-450HLF has 50 positions loaded; the 86837-451HLF is a different position variant within the same BERGSTIK II series. Both share the same 0.100" pitch, 2-row layout, and tin-plated contacts — the position count is the selection difference.
