The 4-103747-0-13 is a single-row, 13-position unshrouded header from TE's AMPMODU Mod II series. The breakaway design means the 13-position strip is part of a longer carrier; you can snap off shorter lengths if needed, but this order code ships the full 13-position stick. The tin-lead post finish (100 µinch) is a legacy solder alloy; the part is RoHS non-compliant per the current directive.
The 0.100" pitch gives a comfortable 2.54 mm between pin centres, which routes easily on single-sided boards and leaves room for a trace between pads on two-layer designs. With a 0.230" mating pin length, the receptacle needs to capture at least that depth for full contact wipe.
No official successor or replacement has been issued. The part is RoHS non-compliant due to the tin-lead post finish; if your BOM requires RoHS exemption documentation, confirm that at quote time. Sourced through independent distribution channels against your RFQ. The bulk package means parts ship in tubes or bags, not tape-and-reel.
