A 6-pin, 4.2mm pitch header, but with a right-angle mount instead of straight. Electrical ratings must be verified.
Find substitutes for the ZX-5557-4.2-2-3PZZ, a 6-pin, 4.2mm pitch straight header. Alternatives exist but require careful verification of mounting style and electrical ratings.
Some candidates have a right-angle mount instead of straight, requiring a PCB layout change.
Key candidates have unverified current/voltage ratings that must be checked against the datasheet.
No direct, verified pin-to-pin replacement has been identified. DLL-5569-6A is a strong form-fit candidate pending review of its electrical specifications.
The DLL-5569-6A is the strongest candidate, matching the form factor, but requires datasheet verification for electrical ratings.
The primary risk is mechanical incompatibility from using a right-angle part or electrical overstress if a candidate's ratings are below the target's 5A/250V.
