It uses a screw - rising cage clamp termination, accepting wire from 14-30 AWG, and is rated for 12 A at 300 V. The green polyamide (PA66) housing provides a visible color code for circuit identification in multi-block layouts. ## Side-Entry Wire Orientation and Interlocking The mating orientation is horizontal with the board, meaning wires enter from the side parallel to the PCB surface — a space-saving arrangement when the board sits against a panel or enclosure wall. The interlocking (side) feature allows multiple 284391-8 blocks to be ganged together side-by-side, forming a continuous multi-position terminal strip without a separate jumper bar. This reduces assembly hardware and keeps the wiring plane flat. ## Termination and Hardware Specs Each position uses an M3 screw with a specified torque of 0.25 Nm (2.2 Lb-In). The rising cage clamp — brass with nickel plating — pulls the wire against the current bar as the screw tightens, providing a gas-tight connection that resists thermal cycling. Both the screw and clamp are brass with nickel plating; the contact material is brass with tin plating, a combination that suits the 12 A rating in dry indoor environments.","metaTitle":"284391-8 TE Buchanan Terminal Block, 8 Pos, 3.5mm, 12 A","metaDescription":"284391-8 TE Connectivity Buchanan PCB terminal block, 8 positions, 3.50 mm pitch, 12 A, 300 V, screw rising cage clamp, green housing, active production.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"RoHS 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":"8","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":"$4.4600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.46000","currency":"USD"},{"qty":10,"price":"$3.97300","currency":"USD"},{"qty":25,"price":"$3.95320","currency":"USD"},{"qty":50,"price":"$3.91260","currency":"USD"},{"qty":100,"price":"$3.52740","currency":"USD"},{"qty":250,"price":"$3.50716","currency":"USD"},{"qty":500,"price":"$3.24360","currency":"USD"},{"qty":1000,"price":"$2.89897","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/1a7612b241adf0d187deae13df93b453.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 284391-8 and how do I get a price?","answer":"Submit a request for quote (RFQ) for current pricing and availability — these are confirmed at quote time and vary with market conditions."},{"question":"What is the pitch and number of positions of 284391-8?","answer":"The 284391-8 has 8 positions at a 0.138\" (3.50 mm) pitch, making it a single-row, single-level terminal block for PCB mounting."},{"question":"Can I use 284391-8 with 14 AWG wire?","answer":"Yes, the 284391-8 accepts wire from 14-30 AWG, so 14 AWG solid or stranded wire fits within the specified range for the rising cage clamp termination."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/284391-8","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/284391-8 when reusing this data.
