Frequently asked questions
Is 45280-0401 the correct part for a Micro-Fit 3.0 4-circuit vertical application?
Yes — the description explicitly lists it as a Micro-Fit 3.0 header, vertical orientation, 4 circuits, with CPI keying. Confirm your mating receptacle also carries CPI polarization; a standard Micro-Fit 3.0 receptacle will not mate with this header.
What is the closest pin-compatible alternative to 45280-0401?
No pin-compatible alternative is listed in the evidence. The Micro-Fit 3.0 family includes other vertical headers with different circuit counts or keying options, but a direct replacement for this specific 4-circuit CPI variant is not identified. Confirm the BOM position and mating half before sourcing an alternate.
