Is there a pin-compatible replacement for MX250-3.5-02P-B-GY01-Cu-A?

Parts like XY2500F-G-3.5-2P are likely pin-compatible as they follow industry standards for 3.5mm pluggable blocks, but this must be confirmed by comparing datasheet drawings.

What risks should I check before replacing MX250-3.5-02P-B-GY01-Cu-A?

Check three key areas: 1) Electrical ratings (Voltage ≥ 300V, Current ≥ 8A). 2) Mechanical fit (housing dimensions, pin spacing). 3) Wire gauge compatibility (target is 22-16 AWG).

MX250-3.5-02P-B-GY01-Cu-A Alternatives, Datasheet & Cross Reference | Cybermax

Finding a replacement for the MAX MX250-3.5-02P-B-GY01-Cu-A requires matching its 2-position, 3.5mm pitch, 300V/8A ratings, and pluggable form factor. Several alternatives exist.

AI replacement insight

Electrical risklow

Low if voltage and current ratings are matched or exceeded.

Package riskmedium

Requires datasheet verification of all mechanical dimensions and pinout.

Sourcing risklow

This is a common connector type with multiple suppliers.

Can it be replaced directly?

No official direct replacement is listed, but several manufacturers offer form-fit-function compatible 2-position, 3.5mm pitch pluggable terminal blocks.

Best replacement path

Select a cross-vendor pluggable terminal block like the XINLAIYA XY2500F-G-3.5-2P, which matches key electrical ratings. Always verify mechanical drawings.

Main risk

The main risk is mechanical incompatibility. While electrical ratings may match, slight differences in housing dimensions or locking mechanisms can prevent a proper fit.

Recommended alternatives

A 2-position, 3.5mm pitch pluggable terminal block with matching 300V/8A ratings.
