MCGWF085P10-TP is not a footswitch. It is an MCC (Micro Commercial Components) P-channel power MOSFET. The manufacturer product page currently lists the related MCG085P10-TP; the manufacturer datasheet is titled MCG085P10 and does not show a footswitch product.
Verified manufacturer-datasheet specifications for MCG085P10:
Device: single P-channel MOSFET
Package: surface-mount DFN3333, approximately 3.2–3.3 mm square
Drain-source rating: −100 V
Gate-source rating: ±20 V
Continuous drain current: −14 A
RDS(on): 85 mΩ nominal headline value; manufacturer page specifies 0.085 Ω at VGS = −10 V and 0.102 Ω at VGS = −4.5 V
Therefore no switch can be mechanically or electrically interchangeable with this MPN. The candidates below are alternatives for the requested pedal-control function: a low-voltage, momentary SPST-NO input to a microcontroller. They require their own footprints and suitable mechanical actuators/enclosure arrangements.
SKHCBEA010 is the strongest general choice when the enclosure provides a mechanical plunger or foot-actuated cap:
through-hole PCB mounting gives better board retention than an ordinary SMD tactile switch;
large 12×12 mm body;
momentary SPST-NO behavior is appropriate for an ATtiny input using its internal pull-up;
1,000,000-cycle mechanical life;
established ALPSALPINE manufacturer;
1,280 pieces were shown in stock when checked.
Best sealed option: KSC442G 70SH LFS PF
Choose this when moisture/dust sealing is more important. It is IP67 and rated for 1,000,000 operations, but it is SMD and had much lower inventory. A PCB-mounted tactile switch must not directly absorb full human foot force without a suitable enclosure-mounted actuator, force spreader, and travel stop.
Important mechanical warning
These parts are PCB tactile switches, not traditional metal panel-mount guitar-pedal stomp switches. For reliable foot operation, the enclosure should carry the mechanical load and transfer only controlled travel/force to the switch. Directly stepping on a PCB-mounted tactile switch can crack solder joints or the PCB even when the switch itself has a high cycle rating.
