Is there a pin-compatible replacement for TSC015A05026A?

While several parts share the same 4.5x4.5mm 4-pin SMD footprint, no exact pin-to-pin replacement with identical height and force has been confirmed. Pinout is likely compatible within the BZCN TSC015A series, but mechanical parameters differ.

What risks should I check before replacing TSC015A05026A?

Before replacing, you must verify the actuator height to ensure it fits your enclosure and button cap. Also, check the operating force, as a difference will change the button's feel for the end-user.

Finding a substitute for the BZCN TSC015A05026A tactile switch requires matching its 4.5x4.5mm footprint, 5.0mm actuator height, and 260gf operating force. Alternatives exist but often differ in height or force, requiring careful review.

AI replacement insight

Electrical risklow

Voltage and current ratings are common and easily matched.

Package riskhigh

Actuator height is a critical mechanical parameter that varies widely between part numbers.

Firmware risklow

Not applicable for a simple mechanical switch.

Can it be replaced directly?

No direct, verified pin-to-pin replacement has been identified. All candidates require review of mechanical fit (actuator height) and operating force.

Best replacement path

Find a switch in the same BZCN TSC015A series with a matching '50' height code and '26' force code. If unavailable, TSC015A04818B is a close option but requires verifying the impact of its lighter force and shorter actuator.

Main risk

The primary risks are mechanical incompatibility due to different actuator heights and a change in user feel from mismatched operating forces.

Recommended alternatives

Functionally similar switch with a lighter actuation force and slightly shorter actuator; requires design review.
