Product details

Board-to-Board Stacking Fit

The 71991-304HLF: Gold at this thickness handles 500+ cycles before exposing the nickel underplate — a solid margin for test points, modular subassemblies, or field-replaceable cards.

Position Count and Peer Comparison

Other position variants in the series include 4-position (71991-302LF) and 16-position (71991-308LF), all sharing the same pitch, plating, and stack height — so the same header family can scale across a product line without requalifying the mating interface.

Application Range and Housing

In high-vibration environments, a secondary retention method (board-mount screws or potting) should be considered.

Frequently asked questions

What is the pitch of the 71991-304HLF?

The mating pitch is 0.100" (2.54mm) on both rows, with a row-to-row spacing of 0.100" (2.54mm).

Is the 71991-304HLF RoHS compliant?

Yes, it is RoHS compliant.

What is the mated stack height for this connector?
