The 1.25mm pitch packs 40 positions into a compact footprint, and the vertical orientation keeps the mated wire assembly perpendicular to the PCB — useful when the z-height above the board is unconstrained but the board-edge real estate is tight.","metaTitle":"Molex 504187-4070 Micro-Lock 1.25mm Vertical Header 40C","metaDescription":"Molex 504187-4070 Micro-Lock 1.25mm pitch vertical header, 40 circuits, ROHS3 compliant, active production.

The header's vertical pins engage the receptacle's contacts in a straight-through mate; confirm the circuit count matches the 40-position layout."},{"question":"Does 504187-4070 have a locking mechanism?","answer":"The Micro-Lock 1.25mm series includes a positive latch on the header that engages the receptacle housing, providing audible and tactile feedback when mated. This latch resists accidental disconnection under vibration or cable strain."},{"question":"What is the current rating of Molex Micro-Lock 1.25mm header?","answer":"The per-contact current is limited by the narrow pitch and contact beam geometry; derate for higher ambient temperatures per the product drawing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/504187-4070","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/molex/504187-4070 when reusing this data.
