The Amphenol ICC 79821-462HLF is a 62-position, dual-row unshrouded header from the BERGSTIK® II series, built on the standard 0.100" (2.54 mm) pitch grid. It carries 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts throughout — including a thick 100.0 µin (2.54 µm) tin finish on the mating surface. The push-pull friction lock holds the pair together in moderate-vibration environments, and the UL94 V-0 black housing meets the flame-rating requirement for equipment inside an enclosure. This is a workhorse board-to-board or wire-to-board interconnect for internal PCB layouts where the footprint and pin count are the primary drivers.
What the ratings mean for the fit
The 0.100" (2.54 mm) pitch is the classic DIP grid — it matches standard perf-board layouts, 0.1-inch ribbon cable IDC connectors, and legacy through-hole patterns. The 62 positions across two rows means the board footprint is a 31-pin-per-row layout; the mating half must be a 62-position dual-row receptacle (unshrouded or shrouded) on the same 0.100" row spacing. The 5 A per circuit rating is typical for a tin-plated header at this pitch — adequate for signal and moderate power duty, but not a high-current bus. The 100.0 µin tin on the mating side is a thick, durable finish for moderate mating cycles; if the application requires frequent field-service or a corrosive environment, a gold-plated sibling would be the better choice.
Deployment context
As an unshrouded header with a push-pull friction lock, this connector is intended for internal board-to-board or wire-to-board connections where the mated pair is not subject to high vibration or cable strain. The through-hole solder termination gives a reliable mechanical anchor on the PCB, and the UL94 V-0 housing makes it suitable for equipment inside an enclosure where flame-rating is a compliance requirement.
Sourcing and lifecycle
The 79821-462HLF carries an active lifecycle status. No official successor or direct cross-reference is on record — the BERGSTIK II series is broad, and the 62-position dual-row variant is the part to match against the BOM line.
