This builds a multi-position strip at the same 3.50 mm pitch — useful when your BOM calls for more than three circuits but you want to keep a single continuous footprint on the PCB. The interlock is mechanical only; electrical continuity between blocks is handled by your PCB traces or jumpers. ## Termination and Torque Specs The rising cage clamp accepts stripped wire directly into the clamp opening. The M3 screw has a recommended torque of 0.25 Nm (2.2 Lb-In) — overtightening can strip the brass threads or deform the clamp plate. Both the screw and clamp are brass with nickel plating, which resists corrosion in industrial cabinet environments.","metaTitle":"TE Connectivity 284391-3 Buchanan Terminal Block, 3 Pos","metaDescription":"TE Connectivity 284391-3 Buchanan PCB terminal block, 3 positions, 3.50mm pitch, 12 A, 300 V, side-entry rising cage clamp, green housing, active production.","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":"Green","Pitch":"0.138\\\" (3.50mm)","Series":"Buchanan","Current":"12 A","Package":"Bulk","Voltage":"300 V","Features":"Interlocking (Side)","Wire Gauge":"14-30 AWG","Screw Thread":"M3","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"0.25 Nm (2.2 Lb-In)","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Wire Termination":"Screw - Rising Cage Clamp","Mating Orientation":"Horizontal with Board","Base Product Number":"284391","Positions Per Level":"3","Operating Temperature":"-","Clamp Material - Plating":"Brass - Nickel Plated","Screw Material - Plating":"Brass - Nickel Plated","Contact Material - Plating":"Brass - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.33000","currency":"USD"},{"qty":10,"price":"$1.24200","currency":"USD"},{"qty":25,"price":"$1.19600","currency":"USD"},{"qty":50,"price":"$1.18460","currency":"USD"},{"qty":100,"price":"$1.06900","currency":"USD"},{"qty":250,"price":"$1.03432","currency":"USD"},{"qty":500,"price":"$0.94188","currency":"USD"},{"qty":1000,"price":"$0.84365","currency":"USD"},{"qty":5000,"price":"$0.76275","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/1a7612b241adf0d187deae13df93b453.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 284391-3 and what is the lead time?","answer":"Submit an RFQ for your quantity and target delivery window."},{"question":"What is the wire gauge range for 284391-3?","answer":"The 284391-3 accepts 14-30 AWG solid or stranded wire.
