No official successor part number is listed by the manufacturer. The MTA-100 series continues in production with RoHS-compliant tin or gold finishes — a direct pin-compatible replacement would need the same 13-position, 0.100\" pitch, right-angle footprint, but with a lead-free plating. Available through independent surplus and distribution channels. Post length is 0.110\" (2.79 mm), which suits standard 0.062\" PCBs with room for the solder fillet.","metaTitle":"1-644694-3 TE Connectivity MTA-100 Header, 13 Pos, Obsolete","metaDescription":"1-644694-3 TE Connectivity AMP MTA-100 unshrouded header, 13 circuits, 0.100\" pitch, right-angle through-hole, tin-lead finish.
