Is there a pin-compatible replacement for TS-1088R-02526?

No pin-compatible replacement has been verified. Candidates reviewed have different footprints or pin counts (e.g., 4-pin vs. the target's 2-pin layout), preventing direct substitution on an existing PCB.

What risks should I check before replacing TS-1088R-02526?

The primary risk is mechanical incompatibility. Before substituting, you must verify the candidate's footprint, pinout, and height against your PCB layout and enclosure. Also confirm the operating force (gf) to maintain the desired tactile feel.

TS-1088R-02526 is a compact 2.5mm height, top-actuated SMD tactile switch. Finding a drop-in replacement requires matching its 3.9x2.93mm footprint, 2-pin layout, and 260gf operating force.

AI replacement insight

Package riskhigh

No candidates match the target's 3.9x2.93mm 2-pin footprint, requiring a PCB redesign.

Electrical risklow

Several candidates match the voltage, current, and operating force specifications.

Can it be replaced directly?

No, a direct drop-in replacement is not available among the candidates reviewed. All options have critical mechanical differences in footprint or pinout.
