Product details

19-Pin Breakaway Header for Prototype and Production

The gold mating finish (30.0 µinch) on the square pins handles repeated connect-disconnect cycles without surface oxidation.

The push-pull fastening keeps insertion force low for bench-level assembly.

Contact base is copper alloy with tin-lead post finish (100.0 µinch) and gold mating surface. RoHS compliance status should be verified against the specific date code — the tin-lead post finish may restrict use in fully RoHS-exempt assemblies.

Frequently asked questions

Does 4-103239-0-19 have a direct replacement or cross-reference?

No official successor or cross-reference from TE Connectivity for this exact breakaway variant. The AMPMODU Mod II series includes other position counts, but a 19-position unshrouded header with gold finish has no listed pin-compatible alternative in the same series.

What is the mating connector for 4-103239-0-19?

Any standard 0.100-inch (2.54 mm) pitch receptacle that accepts 0.025-inch square posts. AMPMODU Mod II socket housings are a direct match, but industry-standard receptacles with the same pitch and post size will work.

Is 4-103239-0-19 RoHS compliant?

The contact post finish is tin-lead (100.0 µinch), which may not meet RoHS requirements for lead content. Verify compliance against your specific application date code and exemption status.
