Is there a pin-compatible replacement for XY350V-3.5-4P?

While several parts share the same 3.5mm pitch and 4-position layout, a true pin-to-pin replacement requires detailed dimensional verification. MX250-3.5-04P-A-GY01-Cu-A is the most likely candidate but should be tested for fit.

What risks should I check before replacing XY350V-3.5-4P?

The main risks are mechanical. Check the wire entry orientation (vertical vs. right-angle) for clearance and the overall connector dimensions. Also, verify the candidate's wire gauge range is suitable for your application.

AI replacement insight

Electrical risklow

Candidates meet or exceed voltage/current ratings.

Package riskmedium

Some candidates have a different form factor (wire entry angle) that requires verification.

Can it be replaced directly?

No drop-in replacement is confirmed without a dimensional check, but MX250-3.5-04P-A-GY01-Cu-A is a very strong candidate for a functional replacement.

Best replacement path

MX250-3.5-04P-A-GY01-Cu-A offers the best functional match with an identical vertical orientation and improved current rating.

Main risk

Mechanical incompatibility due to different wire entry orientations (vertical vs. right-angle) in some alternatives.

Recommended alternatives

A 4-position, 3.5mm pitch vertical plug with a higher current rating (8A) and similar voltage rating.
