Is there a pin-compatible replacement for USB-231-BRW?

Not without verification. While several candidates like 901-242A1011D10100 are 'form, fit, and function' matches, they are not confirmed to be pin-compatible. The exact dimensions and pin spacing of the PCB layout must be compared between the original part's datasheet and the candidate's datasheet.

What risks should I check before replacing USB-231-BRW?

The main risk is mechanical: ensure the substitute's PCB footprint (pin and mounting tab locations) matches your board layout. The second risk is electrical: avoid candidates with a lower current rating (e.g., 1A) if your application requires the full 1.5A.

AI replacement insight

Package riskmedium

PCB footprint (pin spacing, mounting tabs) must be verified against datasheet drawings to ensure mechanical fit.

Electrical risklow

Most candidates match or exceed voltage/current ratings. Some have lower current ratings and should be avoided unless the load is known to be low.

Sourcing risklow

Multiple similar alternatives exist from the same manufacturer, suggesting good availability within that brand.

Can it be replaced directly?

There are several strong candidates that match the form factor and electrical ratings, but no drop-in replacement can be confirmed without verifying the PCB footprint against the datasheet drawings. 901-242A1011D10100 is the most promising option.

Best replacement path

Verify the PCB footprint of 901-242A1011D10100, which matches all key electrical and mechanical specifications.

Main risk

The primary risk is mechanical incompatibility. While candidates match the right-angle, through-hole style, the exact pin spacing and mounting peg locations (PCB footprint) can vary between manufacturers and must be verified.

Recommended alternatives

A strong alternative with matching ratings and mounting, pending PCB footprint verification.
