Package: SMDXKB ConnectionPushbutton SwitchesWith Lamp: 无Pin Style: -IP Rating: -Voltage Rating (AC): -Contact Current: 50mA

TS-1187A-C-E-B is a 5.1mm SMD tactile switch. Listed alternatives need FAE review because pinout or footprint evidence is incomplete.

AI replacement insight

Electrical riskmedium

Most kept parts match 12V/50mA, but contact resistance is missing.

Package riskhigh

Body sizes differ and land patterns are not supplied.

Firmware risklow

Passive switch; no firmware interface expected.

Sourcing riskmedium

Some candidate lifecycles are '-'.

Can it be replaced directly?

No pin-compatible replacement is proven from the provided fields.

Best replacement path

Start with same-function SMD SPST-NO tactile parts, then verify footprint, pinout, force, life, and contact resistance.

Main risk

Mechanical footprint and pinout are not verified.
