Product details

What This Breakaway Header Does in a Board-to-Board or Cable Assembly

The gold-plated mating surface (30 µinch) and tin-plated solder posts (100 µinch) balance signal integrity with cost — the gold handles repeated mating cycles in clean environments, while the tin post wets well during wave solder.

Unshrouded vs. Shrouded — When to Pick This Header

Unshrouded headers expose the pins for easy probing and low-profile mating, but offer no keying or strain relief. For a closer gold-plating match, the 1376779-2 also carries a 3 A rating and gold mating finish, but at 8 µinch thickness — a quarter of this part's 30 µinch. If you need the higher cycle life that 30 µinch gold provides, 9-146277-0-04 is the right call.

Frequently asked questions

What is the mating connector for 9-146277-0-04?

This is an unshrouded male pin header.

What is the closest functional second-source for 9-146277-0-04?

The 1-1871673-2 is a 4-position header from the same series but is shrouded (4-wall), uses a 2.50 mm pitch, and has a tin mating finish — it is not a form-fit-function replacement. For a gold-plated alternative, the 1376779-2 has 8 µinch gold (vs. 30 µinch here) and a 3 A rating, but the pinout and footprint must be verified.
