RoHS non-compliant — if your BOM requires RoHS, this part won't pass without an exemption. Confirm your assembly's material restrictions before committing. ## Sourcing and Compliance — What to Know Before You Order Shipped in bag packaging — loose pieces, not tape-and-reel. Fine for hand-assembly or low-volume production; if you need automated pick-and-place, check whether a tube or reel option exists for this series.","metaTitle":"22-28-4121 Molex KK 100 Header 12 Circuit Tin Breakaway","metaDescription":"22-28-4121 Molex KK 100 breakaway header, 12 circuits, tin-plated.

If your application requires RoHS, this part is not suitable without an exemption."},{"question":"What is the pinout of Molex 22-28-4121?","answer":"The pinout is a single row of 12 pins on 0.100-inch pitch. The breakaway design allows snapping the strip to fewer positions. No additional pinout detail is confirmed beyond the circuit count and pitch."},{"question":"What is the mating connector for 22-28-4121?","answer":"The mating half is a KK 100 series crimp receptacle housing and terminals — typically a 0.100-inch pitch housing that accepts the matching crimp terminal. Confirm the specific housing part number against your wire gauge and circuit count."},{"question":"What is the equivalent to 22-28-4121 from other manufacturers?","answer":"Pin-compatible alternatives would need to match the 0.100-inch pitch, 12 circuits, single-row breakaway format, and tin plating — verify footprint and mating half compatibility before substituting."},{"question":"Where can I buy 22-28-4121 available via RFQ confirmation?","answer":"Sourced through independent distribution; quoted to order against your BOM quantity.
