Product details

The Amphenol BERGSTIK® II 78511-420HLF is a 20-position, single-row unshrouded male pin header on 0.100" (2.54mm) pitch.

The 0.100" (2.54mm) pitch is the standard 0.100-inch grid — the board footprint is a straight row of 20 plated through-holes on that spacing. The 0.120" (3.05mm) solder tail length suits typical 0.062" to 0.093" PCB thickness. The 5A per-contact rating is conservative for a 0.100" pitch pin; the limiting factor in practice is the temperature rise in the housing, which is UL94 V-0 rated and handles the thermal load.

Frequently asked questions

Is 78511-420HLF RoHS compliant?

The 78511-420HLF is listed with tin-plated contacts and a UL94 V-0 black insulation material, consistent with RoHS compliance for standard commercial connectors. Verify the specific RoHS certificate against the manufacturer's documentation for your jurisdiction.
