Is there a pin-compatible replacement for TSC015A04818B?

While several candidates share the same 4-pin SMD footprint, none are fully pin-compatible without caveats. Differences in height and operating force prevent a direct drop-in replacement.

What risks should I check before replacing TSC015A04818B?

Verify the actuator height to ensure it fits your enclosure and button design. Also, check the operating force (180gf for the original) as a mismatch will change the switch's feel.

AI replacement insight

Package riskhigh

Actuator height varies significantly among candidates, impacting fit.

Electrical risklow

Key electrical ratings (voltage, current) are consistent.

Can it be replaced directly?

There are no confirmed pin-to-pin replacements for TSC015A04818B. All viable candidates have mechanical or functional differences.

Best replacement path

No direct drop-in replacement found. Alternatives require review of mechanical height and operating force.

Main risk

The primary risk is mechanical incompatibility, specifically actuator height and differences in operating force affecting user experience.

Recommended alternatives

A functional alternative with the same footprint and electrical ratings, but a higher operating force and slightly different height.
