The 1-103675-2: This is a 40-position, dual-row breakaway header from the AMPMODU Mod II series. The post finish is tin-lead, which wets well during wave solder but is not RoHS-compliant on the solder side — factor this into your assembly process if you are running lead-free.
Obsolete – Sourcing Reality for the 1-103675-2
This part carries an Obsolete lifecycle status from TE Connectivity. No official successor or replacement part number has been published by the manufacturer. If your BOM calls for this exact order code, the only channel is independent distribution — we source it per RFQ against your quantity, with availability and pricing confirmed at quote time. Because the header is unshrouded and uses a standard 0.100" pitch, a functional equivalent from another manufacturer's breakaway header family may fit the same footprint, but the pin length, plating, and overall contact length (0.440") must be verified against your mating receptacle and board stack-up. No pin-compatible drop-in is listed on the official record.
Termination is through-hole solder.
