Product details

The Amphenol FCI 87901-128HLF is a 28-position dual-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54mm) pitch. Rated 5A per circuit at 110V, with 30.0µin (0.76µm) gold plating on the mating surface — the gold thickness supports repeated mating cycles without the contact fretting you would see with tin on a frequently disconnected line.

Within the BERGSTIK® II family, the 28-position 87901-128HLF sits between the 20-position and 36-position variants at the same 0.100" pitch and dual-row layout. The selection decision is purely the circuit count matching the BOM — the footprint, current rating, and plating grade are consistent across the loaded-position range.

Termination is through-hole solder — the 0.120" (3.05mm) post length suits standard PCB thicknesses from 0.062" to 0.093".

Frequently asked questions

What mates with the 87901-128HLF?

This unshrouded header mates with any 0.100" (2.54mm) pitch dual-row female socket header or IDC receptacle that accepts 0.025" square pins. The 0.820" (20.83mm) mating pin length provides sufficient reach for standard box headers without bottoming out.

Can the 87901-128HLF be used for wire-to-board connections?

Yes — when mated with a female IDC receptacle or crimp-housing socket header on the same 0.100" pitch, it functions as a wire-to-board interconnect. The unshrouded pins require the mating half to provide the wire-side strain relief.
