Ratings That Drive the Fit Decision
The 86837-450HLF: 50 positions loaded all, in two rows at 0.100 inch row spacing — the circuit count matches any BOM line calling for a 50-way dual-row 0.100 inch header, and the pitch confirms footprint compatibility with standard 0.100 inch pitch receptacle housings in the same series. 5 A per circuit current rating at the contact level — the tin plating on both the mating interface and the solder tail (100.0 µin thick) governs the duty: tin is suited for production-level mating cycles where reconnection is infrequent, and the 5 A rating reflects the contact cross-section of phosphor bronze at this pitch. 110 V rating is the voltage ceiling for the insulation and air-clearance geometry at this pitch — at 0.100 inch spacing the creepage and clearance are adequate for logic-level and low-voltage power bus signals, not mains voltage. Through-hole push-pull termination with 0.120 inch (3.05 mm) post length and 0.380 inch (9.65 mm) mating length — the 0.600 inch overall contact length (15.24 mm) tells you the minimum board thickness the pins will accept; the push-pull fastening type means the header relies on friction retention rather than a screw-lock or latching clip, so check whether the mating receptacle has a friction or spring-latch retention feature.
Material and Environmental Ratings
Phosphor bronze contact base material with tin plating throughout — the 100.0 µin (2.54 µm) mating-side thickness is a production-grade tin finish, not a thin flash coat, which gives reasonable resistance to oxidation and multiple mating cycles in a controlled factory environment. UL94 V-0 black housing — the flammability rating confirms the housing material will not propagate flame and meets the baseline fire-retardance requirement for industrial and telecom equipment enclosures. Insulation height of 0.100 inch (2.54 mm) — this is the standoff dimension between the board surface and the bottom of the housing, which controls how much clearance the header provides above the PCB surface; for board-stacking applications this affects the mated pair's overall profile.
Where and How It Is Used
Sourcing
Listed as Active — quoted to order against BOM quantity. No official successor or cross-reference listed for this part number. The base product number is 86837, which may indicate a broader family series; confirm any variant comparison against the full 86837 series before specifying a substitute. Confirm the mating receptacle's circuit count and keying before committing — the 50-position dual-row 0.100 inch format is shared across multiple BERGSTIK II variants; the shrouding, mounting orientation, and retention style of the receptacle must match the push-pull male header for a reliable board-to-board pair.
