A built-in board guide aids alignment during assembly. The 4-wall shrouding protects the pins from accidental shorting during handling. The latch holder and IP-rated construction make it a candidate for environments with moisture exposure or moderate vibration — think washing machine control boards, automotive lamp harnesses, or outdoor HVAC controls.","metaTitle":"JST WPJ B03B-WPJES-3(LF)(SN) Header, 3-Pos 5.00mm, 7A","metaDescription":"JST B03B-WPJES-3(LF)(SN) WPJ series 3-position header, 5.00mm pitch, 7A rated, waterproof IP rating, through-hole solder, latch holder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"JST Sales America Inc.","Style":"Board to Cable/Wire","Series":"WPJ","Package":"Bulk","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"1","Pitch - Mating":"0.197\\\" (5.00mm)","Product Status":"Active","Voltage Rating":"300V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Blue","Insulation Height":"0.843\\\" (21.41mm)","Ingress Protection":"Waterproof","Base Product Number":"B03B-WPJ","Insulation Material":"Polybutylene Terephthalate (PBT), Glass Filled","Number of Positions":"3","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.130\\\" (3.30mm)","Current Rating (Amps)":"7A","Operating Temperature":"-25°C ~ 85°C","Mated Stacking Heights":"25.3mm","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3352","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/B03B-WPJES-3(LF)(SN)/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of JST B03B-WPJES-3(LF)(SN)?","answer":"The mating pitch is 0.197\" (5.00 mm).
