It is designed to mate with a Buchanan-style plug or receptacle to create a wire-to-board connection for power distribution or signal routing in industrial control panels. Rated 12 A per contact at 300 V, with a tin-plated mating finish. The side stacking feature allows multiple headers to lock together side-by-side, building a wider multi-pole terminal block without a custom PCB layout — a practical space saver in a crowded cabinet. Through-hole solder termination, vertical header orientation. The contact tail length is 0.138\" (3.50 mm) — this sets the solder joint depth into the plated through-hole and the standoff height above the board. Insulation height is 0.079\" (2.00 mm), which is the clearance from the top of the housing to the board surface — relevant for component keep-out on the opposite side.","metaTitle":"2-1546931-5 TE Connectivity Buchanan Header, 25 Pos, 5.00 mm","metaDescription":"2-1546931-5 TE Connectivity AMP Connectors Buchanan series header, 25 positions, 0.197\" pitch, 12 A, 300 V, tin-plated, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Type":"Header, Male Pins, Unshrouded","Color":"Black","Pitch":"0.197\\\" (5.00mm)","Series":"Buchanan","Package":"Bulk","Features":"Side Stacking","Screw Size":"-","Current - UL":"12 A","Voltage - UL":"300 V","Current - IEC":"-","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"-","Plug Wire Entry":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Insulation Height":"0.079\\\" (2.00mm)","Termination Style":"Solder","Wire Strip Length":"-","Header Orientation":"Vertical","Ingress Protection":"-","Base Product Number":"1546931","Contact Tail Length":"0.138\\\" (3.50mm)","Number of Positions":"25","Positions Per Level":"25","Contact Mating Finish":"Tin","Operating Temperature":"-","Wire Gauge or Range - AWG":"-","Wire Gauge or Range - mm²":"-","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.0000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ab14f390e742ecb521d86528f32d936a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact mating connector for 2-1546931-5?","answer":"This unshrouded header mates with a Buchanan series plug or receptacle that accepts 5.00 mm pitch crimp terminals.
