The 1.27 mm (0.050-inch) mating pitch and 2.54 mm (0.100-inch) row spacing set the PCB footprint: 25 contacts per row in a staggered grid. This pitch is the tightest common spacing for this class, which means the board layout engineer must plan for fine-pitch trace escape between the through-hole posts. ## Right-Angle Through-Hole Termination","metaTitle":"103911-4 TE Connectivity AMPMODU System 50 Receptacle","metaDescription":"103911-4 TE Connectivity AMPMODU System 50 board-to-board receptacle, 50 positions, 1.27mm pitch, 30VAC, 1A, gold mating, right-angle through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Board","Series":"AMPMODU System 50","Package":"Tube","Features":"Board Guide","Termination":"Solder","Applications":"-","Contact Type":"Female Socket","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Receptacle","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.050\\\" (1.27mm)","Product Status":"Active","Voltage Rating":"30VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.217\\\" (5.51mm)","Ingress Protection":"-","Base Product Number":"103911","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"50","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin-Lead","Contact Length - Post":"0.100\\\" (2.54mm)","Current Rating (Amps)":"1A","Operating Temperature":"-65°C ~ 105°C","Mated Stacking Heights":"-","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.7117","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/1f2a71d954bccea1e7030ae7dacbface.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/103911-4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for 103911-4?","answer":"The 103911-4 is the direct fit for the design; any alternative would require a board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/103911-4","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/103911-4 when reusing this data.
