Is there a pin-compatible replacement for MX126R-5.0-02P-GN01-Cu-S-A?

No pin-compatible replacement was identified. All candidates reviewed have a vertical mounting style, which is mechanically different from the target's right-angle configuration. A true pin-compatible part must match the 90-degree pin orientation.

What risks should I check before replacing MX126R-5.0-02P-GN01-Cu-S-A?

The primary risk is mechanical incompatibility. The target is a right-angle connector; using a vertical substitute will change the wire entry direction and may interfere with the enclosure or other components. Always verify the substitute's datasheet for mechanical dimensions and pin orientation.

The MAX MX126R-5.0-02P-GN01-Cu-S-A is a 2-position, 5.0mm pitch right-angle terminal block rated for 300V/10A. Finding a direct replacement requires matching the right-angle mounting style, pitch, and electrical ratings.

AI replacement insight

Package riskhigh

Candidate mounting angle (vertical) does not match target (right-angle), requiring PCB redesign.

Can it be replaced directly?

No direct, drop-in replacement was found. All candidates are vertical mount, while the target is right-angle, making them mechanically incompatible.

Best replacement path

Search for 2-position, 5.0mm pitch, right-angle terminal blocks with 300V/10A+ ratings.

Main risk

Mechanical form-factor mismatch due to different mounting angles (vertical vs. right-angle).

Recommended alternatives

Functionally similar with a higher current rating, but has a vertical mount instead of right-angle.
