The black housing and vertical wire entry (top entry, perpendicular to the PCB) suit it for control cabinets, power supplies, and industrial I/O boards where a serviceable screw termination is preferred over a crimped connector. ## Ganging Blocks for Multi-Circuit Runs The 1546073-2 carries an interlocking side feature that lets multiple 2-position blocks snap together into a longer strip — useful when a 4-, 6-, or 8-position assembly is needed without ordering a different base part number. The 5.08 mm pitch stays consistent across the gang, so the PCB footprint can be laid out as a repeating pattern. For a fixed multi-position requirement, the 1546073-2 at 2 positions per level is the building block; there is no single 4-position variant in this exact form factor, so ganging is the intended approach.","metaTitle":"TE Buchanan 1546073-2 Terminal Block, 2 Pos, 5.08mm, 17.5A","metaDescription":"TE Connectivity Buchanan 1546073-2 PCB terminal block, 2 positions, 5.08mm pitch, 17.5 A, 300 V, rising cage clamp, M3 screw, black PA66 housing.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors","Wire-to-Board Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Black","Pitch":"0.200\\\" (5.08mm)","Series":"Buchanan","Current":"17.5 A","Package":"Bulk","Voltage":"300 V","Features":"Interlocking (Side)","Wire Gauge":"12-30 AWG","Screw Thread":"M3","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"0.79 Nm (7.0 Lb-In)","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Wire Termination":"Screw - Rising Cage Clamp","Mating Orientation":"Vertical with Board","Base Product Number":"1546073","Positions Per Level":"2","Operating Temperature":"-40°C ~ 105°C","Clamp Material - Plating":"Brass - Nickel Plated","Screw Material - Plating":"Brass - Nickel Plated","Contact Material - Plating":"Brass - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7500","priceTiers":[{"qty":1,"price":"$0.75000","currency":"USD"},{"qty":10,"price":"$0.72300","currency":"USD"},{"qty":25,"price":"$0.72000","currency":"USD"},{"qty":50,"price":"$0.69580","currency":"USD"},{"qty":100,"price":"$0.58340","currency":"USD"},{"qty":250,"price":"$0.54696","currency":"USD"},{"qty":500,"price":"$0.51656","currency":"USD"},{"qty":1000,"price":"$0.45275","currency":"USD"},{"qty":5000,"price":"$0.39502","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546073-2/alternatives.json"},"ai":{"faq":[{"question":"What wire gauge does the 1546073-2 accept?","answer":"The rising cage clamp accepts 12-30 AWG wire.
