It's a board-to-board interconnect, terminated by solder, and mounts at the board edge in a right-angle orientation. Typical use is parallel-PCB stacking or mezzanine links where a single connector type simplifies the BOM and the 4.00mm pitch gives enough room for 6 A per circuit without crowding board traces. ## Why the Hermaphroditic Design Matters for the Build Because the 1-1954289-2 is hermaphroditic, you order one part number for both ends of the board-to-board link. That cuts inventory line items and eliminates the risk of mismatching a plug to a receptacle on the assembly floor. The right-angle SMT termination places the connector flush at the board edge, which saves z-height in stacked-PCB assemblies and keeps the solder joints accessible for inspection. The 6 A per circuit rating at 125 V is enough for power distribution between boards in industrial control or telecom gear, but the tin contact finish means mating cycles are limited — plan for permanent or infrequent-disconnect installations.","metaTitle":"TE 1-1954289-2 Hermaphroditic Connector, 4 Pos, 4.00mm Pitch","metaDescription":"TE 1-1954289-2 hermaphroditic blade-and-receptacle connector, 4 positions, 0.157\" (4.00mm) pitch, 6 A, 125 V, right-angle SMT.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Wire-to-Board Connectors","LED Lighting Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Pitch":"0.157\\\" (4.00mm)","Style":"Board to Board","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Wire Gauge":"-","Termination":"Solder","Housing Color":"Black","Mating Cycles":"-","Mounting Type":"Board Edge, Surface Mount, Right Angle","Connector Type":"Blade and Receptacle, Hermaphroditic","Contact Finish":"Tin","Fastening Type":"-","Product Status":"Active","Voltage Rating":"125V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Housing Material":"Liquid Crystal Polymer (LCP)","Ingress Protection":"-","Base Product Number":"1954289","Number of Positions":"4","Current Rating (Amps)":"6A","Operating Temperature":"-40°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8734","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/32f7a453d7c1ade2e04bc8cc8d5fe3c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1-1954289-2?","answer":"Submit a request for current pricing and availability — confirmed at quote time through independent distribution."},{"question":"Is 1-1954289-2 hermaphroditic?","answer":"Yes, the 1-1954289-2 is a hermaphroditic blade-and-receptacle connector.
