The exact mating part depends on your wire gauge and circuit count; the receptacle housing and crimp terminals are sold separately. Confirm the mating half has the matching latch to engage the locking ramp."},{"question":"What is the current rating of 2-1445057-4?","answer":"The current rating is listed as 'Varies by Wire Gauge' — the header itself does not set a single ampacity; the limiting factor is the wire size and the crimp terminal used in the mating receptacle. For a given wire gauge, refer to the Micro MATE-N-LOK terminal derating curve in the product drawing."},{"question":"Is 2-1445057-4 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/2-1445057-4","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/2-1445057-4 when reusing this data.
