Is there a pin-compatible replacement for TS-1089S-02526?

No pin-for-pin compatible replacement is confirmed at this time. While some candidates have 4 pins, their package dimensions and land patterns differ from the 4.2mm x 3.25mm footprint of the TS-1089S-02526, necessitating board-level review.

What risks should I check before replacing TS-1089S-02526?

Key risks include package mismatch, requiring a new PCB layout. Also verify the operating force (user feel), actuator travel, and overall height to ensure mechanical and user interface compatibility in your application.

TS-1089S-02526 Alternatives, Datasheet & Cross Reference | XUNPU

The XUNPU TS-1089S-02526 is a 4.2mm x 3.25mm surface-mount tactile switch rated for 12V/50mA. Finding a direct drop-in replacement requires careful matching of its unique footprint, height, and operating force.

AI replacement insight

Package riskhigh

No candidates match the target's 4.2x3.25mm footprint, requiring a PCB redesign.

Electrical risklow

Candidates with matching voltage/current ratings are available.

Sourcing riskmedium

Finding a form-fit replacement is difficult, increasing reliance on redesign efforts.

Can it be replaced directly?

No direct drop-in replacement has been identified. All viable alternatives require a new PCB layout due to footprint differences.

Best replacement path

Functional alternatives requiring board redesign.

Main risk

The primary risk is mechanical incompatibility. The package footprint, height, and actuator feel (force and travel) of alternatives do not match the target.

Recommended alternatives

Functional alternative with same rating but different footprint and much higher operating force.
