AMPMODU System 50 Header — 1.27 mm Pitch, 10 Circuits, SMD with Board Lock
Note: this part is RoHS non-compliant due to tin-lead plating on the solder posts. For RoHS-required builds, verify the exemption or consider a lead-free variant in the same series.
The 1.27 mm pitch and 0.125 inch (3.18 mm) mating pin length are standard for AMPMODU System 50 receptacles. The 10-position dual-row layout mates with any System 50 socket that matches the same pitch, row spacing, and position count — confirm the receptacle part number against the BOM. Board locks are present on the SMD tails — they anchor the header during wave or selective solder reflow and provide mechanical retention against cable pull.
Peer Comparison — 1-1871673-2 vs 104549-1
The 104549-1 offers 10 positions at 1.27 mm pitch with gold mating finish — a different density and plating grade for higher-cycle or denser board layouts.
