Tin-plated contacts on copper alloy are rated 3A per circuit (22 AWG), appropriate for signal-level or low-power duty within a 300V system. The 0.071\" (1.80mm) pitch is the critical board-layout dimension — it determines pad spacing and trace routing width between the two positions. The 3A rating at 22 AWG is a per-contact limit under the stated wire size — derate for smaller gauges or elevated ambient temperature above 25°C. The 300V rating provides adequate headroom for typical low-voltage signal or control circuits. This header mates with the JST LEH series receptacle housing (order code LEHSS-A-xx, where xx is the position count). The receptacle accepts crimp terminals (LEHSS-T) for 22-28 AWG wire. The solder termination on this header is surface-mount, right-angle — no through-hole holes required. The solder retention feature provides additional hold during reflow, reducing tombstoning risk on the two small pads.","metaTitle":"JST BM02B-LEHSS-A-TB(HF) LEH Header, 2-Pos, 0.071\" Pitch","metaDescription":"JST BM02B-LEHSS-A-TB(HF) LEH series 2-position header, 0.071\" (1.80mm) pitch, right-angle SMT, tin-plated contacts, 3A rated.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Wire-to-Board Connectors"],"specifications":{"Mfr":"JST Sales America Inc.","Pitch":"0.071\\\" (1.80mm)","Style":"Board to Cable/Wire","Series":"LEH","Package":"Tape & Reel (TR)","Features":"Solder Retention","Wire Gauge":"-","Termination":"Solder","Housing Color":"Natural","Mating Cycles":"-","Mounting Type":"Surface Mount, Right Angle","Connector Type":"Header, Male Pins","Contact Finish":"Tin","Fastening Type":"-","Product Status":"Obsolete","Voltage Rating":"300V","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Housing Material":"Polyamide (PA9T), Nylon 9T","Ingress Protection":"-","Number of Positions":"2","Current Rating (Amps)":"3A (22 AWG)","Operating Temperature":"-55°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6b514575f6d79e0066fd99df4c9d6226.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BM02B-LEHSS-A-TB(HF) obsolete and what does that mean for procurement?","answer":"Yes, BM02B-LEHSS-A-TB(HF) is officially obsolete.
