What this connector is
The Molex 65863-458 is a 24-circuit, dual-row male header from the Quickie series — a 0.100 inch (2.54 mm) pitch board-to-cable/wire interconnect with a full four-wall shroud and a dedicated keying slot that prevents mis-mating in multi-connector panel builds. The latch lock/eject hooks hold the mated pair under vibration while allowing single-handed disengagement — a practical feature for field service and test-fixture use. Gold or GXT contact plating at 30.0 µin (0.76 µm) on the mating surface gives this member better durability than tin-only siblings in the same series.
Key ratings for fit and selection
The 0.100 inch (2.54 mm) pitch and 24-position dual-row layout are standard for through-hole headers. Contact material is phosphor bronze, insulation is UL94 V-0 thermoplastic, and the 0.640 inch (16.26 mm) insulation height gives the shroud adequate stand-off for cable dress. The 0.105 inch (2.67 mm) tail length and 0.230 inch (5.84 mm) mating length are sized for standard Quickie family receptacles.
Sourcing and lifecycle
Listed Active under — this part is in normal production and quoted to order against BOM quantity. The 65863 base product number anchors this to a known series family, which means cross-referencing within the Quickie line for position-count alternatives is straightforward. Confirm the mating receptacle housing and any panel cut-out dimensions before raising an RFQ.
