Key Parameters

Substitute Part Grouping Explanation

Substitution of the YB225CWSSG01 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Electrical Ratings: 0.4VA current capacity and 28V AC/DC voltage rating
• Switch Function: On-Mom operation required
• Mounting Interface: Panel Mount, Front with 21.00mm x 21.00mm square cutout
• Termination: Solder, Quick Connect - 0.110" (2.8mm) connector type
• Environmental Protection: IP65 rating for dust and water resistance
• Operating Temperature: -25°C to 70°C range
• Mechanical Performance: 1,000,000 cycle mechanical life and 100,000 cycle electrical life
• Actuator Configuration: Plunger for Cap without marking

The YB225CWSPG01 meets all these criteria and is classified as an equivalent substitute part within the YB2 series.

Parameter Comparison
