It accepts 14-22 AWG wire, so it covers the common control-wiring range from a 1.5 mm² power feed down to a 0.34 mm² signal return. The green PA66 housing is the standard Buchanan visual ID — easy to spot in a cabinet full of black or grey blocks. ## Screwless Spring Clamp vs. Traditional Screw Terminal The 1776259-8 uses a screwless leg-spring clamp instead of a screw-and-yoke mechanism. That means no screw torque to check, no risk of backing out under vibration, and faster wire insertion — push the stripped wire into the clamp opening and the spring holds it. The trade-off is that the spring clamp exerts a constant force on the conductor, so you cannot use a ferrule the same way as a screw terminal; stranded wire is inserted directly. The clamp material is stainless steel, so it resists corrosion in humid cabinet environments.","metaTitle":"TE Connectivity 1776259-8 Buchanan Terminal Block, 8 Pos","metaDescription":"TE Connectivity 1776259-8 Buchanan 8-position PCB terminal block, 5.00 mm pitch, 10 A, 300 V, screwless push-in spring termination, green housing, RoHS3","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":"0.197\\\" (5.00mm)","Series":"Buchanan","Current":"10 A","Package":"Bulk","Voltage":"300 V","Features":"-","Wire Gauge":"14-22 AWG","Screw Thread":"-","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"-","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Wire Termination":"Screwless - Leg Spring, Push-In Spring","Mating Orientation":"Vertical with Board","Base Product Number":"1776259","Positions Per Level":"8","Operating Temperature":"-55°C ~ 105°C","Clamp Material - Plating":"Steel, Stainless","Screw Material - Plating":"-","Contact Material - Plating":"Brass - Nickel Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.2400","priceTiers":[{"qty":1,"price":"$11.24000","currency":"USD"},{"qty":10,"price":"$10.16700","currency":"USD"},{"qty":25,"price":"$9.89800","currency":"USD"},{"qty":50,"price":"$9.52160","currency":"USD"},{"qty":100,"price":"$8.82230","currency":"USD"},{"qty":250,"price":"$8.76852","currency":"USD"},{"qty":500,"price":"$8.44574","currency":"USD"},{"qty":1000,"price":"$7.53123","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9c5bd8680d67d9ab5c07f6c883810e99.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1776259-8/alternatives.json"},"ai":{"faq":[{"question":"What wire gauge does the 1776259-8 accept?","answer":"The 1776259-8 accepts 14-22 AWG wire.
