It mates with standard 5 mm pitch pluggable terminal blocks — the unshrouded design gives you clearance for wire exits on the mating plug. Rated 12 A at 300 V per UL, this header handles typical industrial control signals and low-power distribution. ## Mounting and side-stacking feature Vertical through-hole mounting with 0.138\" (3.50mm) solder tail length. The side-stacking feature allows multiple headers to be placed edge-to-edge on 5 mm pitch centres, building wider pin arrays from standard 4-position blocks.","metaTitle":"1546931-4 TE Buchanan 4-Pos 5mm Vertical Unshrouded Header","metaDescription":"1546931-4 TE Connectivity AMP Connectors Buchanan header, 4 positions, 0.197\" (5.00mm) pitch, vertical unshrouded, 12 A / 300 V, UL94 V-0, tin-plated brass","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Header Plugs & Sockets"],"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":"4","Positions Per Level":"4","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":"$0.8100","priceTiers":[{"qty":1,"price":"$0.81000","currency":"USD"},{"qty":10,"price":"$0.78800","currency":"USD"},{"qty":25,"price":"$0.78480","currency":"USD"},{"qty":50,"price":"$0.75840","currency":"USD"},{"qty":100,"price":"$0.63590","currency":"USD"},{"qty":250,"price":"$0.59620","currency":"USD"},{"qty":500,"price":"$0.56308","currency":"USD"},{"qty":1000,"price":"$0.49352","currency":"USD"},{"qty":5000,"price":"$0.43059","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/ab14f390e742ecb521d86528f32d936a.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546931-4/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of 1546931-4?","answer":"0.197\" (5.00mm) pitch, matching the standard 5 mm terminal block footprint."},{"question":"What is the current rating of 1546931-4?","answer":"12 A per UL, at 300 V.
