Submit an RFQ with your target quantity; we source it per order and confirm availability and pricing at quote time. No stock-holding claim — every order is sourced fresh."},{"question":"What is the difference between 641937-1 and 641937-2?","answer":"The 641937-1 has 3 positions with 2 loaded; the 641937-2 has 3 positions with 3 loaded (all positions populated). Both share the same 0.156\" pitch, friction lock, and tin plating. The -1 is a cost-reduced variant for 2-wire circuits."},{"question":"Can 641937-1 be replaced by 641937-2?","answer":"Yes, the 641937-2 is pin-compatible — same body, same pitch, same lock. The -2 has all 3 positions loaded, so it can replace the -1 in a 2-wire application (the extra pin is simply unused). No board spin required."},{"question":"Is 641937-1 RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/641937-1","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/641937-1 when reusing this data.
