Product details

12-Circuit KK 100 Breakaway Header — Tin-Plated, Active Production

The 22-28-4121: This is a 12-circuit, single-row breakaway header from the Molex KK 100 family, with tin-plated pins on 0.100-inch pitch. 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.

Frequently asked questions

Is 22-28-4121 RoHS compliant?

No — 22-28-4121 is RoHS non-compliant. If your application requires RoHS, this part is not suitable without an exemption.

What is the pinout of Molex 22-28-4121?

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.

What is the mating connector for 22-28-4121?

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.

What is the equivalent to 22-28-4121 from other manufacturers?

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.

Where can I buy 22-28-4121 available via RFQ confirmation?

Sourced through independent distribution; quoted to order against your BOM quantity. Availability and current pricing confirmed at quote time.
