Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EVQ-P4403M is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Contact rating: 0.02A @ 15VDC
• Mounting type: Edge Mount, Right Angle
• Actuator type: Rectangular Button
• Actuator length (right angle): 2.10mm
• Actuator orientation: Side Actuated
• Outline dimensions: 6.20mm x 2.55mm
• Operating force: 240gf
• Switch travel: 0.25mm
• Mechanical life: 500,000 Cycles
• Operating temperature range: -40°C ~ 85°C
• Termination style: SMD (SMT) Tab
• Moisture sensitivity level: 1 (Unlimited)

The EVQ-P44B3M meets all these criteria and is classified as a direct substitute. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations
