MPB11106 Equivalent & Substitute Parts Reference

Part Overview

The MPB11106 is a pushbutton switch manufactured by APEM Inc., classified as SPST-NO (Single Pole Single Throw - Normally Open) with a current rating of 300mA at 125V AC. This component features a standard panel mount configuration with rear termination using solder lugs and a red round button actuator. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and new design implementations where this switch type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPB11106 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO
• Switch Function: Must be Off-Mom (Momentary)
• Voltage Rating: Must be 125V AC minimum
• Current Rating: Must be equal to or greater than 300mA
• Mounting Type: Must be Panel Mount, Rear
• Termination Style: Must be Solder Lug
• Actuator Type: Must be Round, Button
• Actuator Color: Must be Red
• Panel Cutout Diameter: Must accommodate 7.36mm or smaller circular opening
• Compliance: Must maintain ROHS3 compliance

The three substitute parts listed below meet all these criteria and are therefore electrically and mechanically compatible with the MPB11106.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing supply chain continuity for applications previously using the obsolete MPB11106. All substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

GPB024A05BR (CW Industries): This substitute provides a current rating of 3A, exceeding the original 300mA specification. The panel cutout diameter of 7.20mm is smaller than the original 7.36mm, allowing direct mechanical fit in existing panel openings. Operating temperature and life cycle data are not specified by the manufacturer.

PS1024ALRED (E-Switch): This substitute provides a current rating of 3A with an operating temperature range of -20°C to 65°C, extending the upper temperature limit by 5°C compared to the original. The panel cutout diameter of 7.20mm accommodates existing panel openings. Mechanical and electrical life ratings are specified at 6,000 cycles, below the original 10,000 cycles.

PS1024ARED (E-Switch): This substitute is functionally identical to PS1024ALRED, with the same current rating of 3A, operating temperature range of -20°C to 65°C, and life cycle specifications of 6,000 cycles. The panel cutout diameter of 7.20mm provides mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts handle the same electrical load as the MPB11106?

A: All three substitute parts are rated for 3A at 125V AC, which exceeds the original 300mA specification. They are electrically compatible for applications within the original current and voltage parameters.

Q: Will the substitute parts fit in existing panel cutouts designed for the MPB11106?

A: The original MPB11106 requires a 7.36mm circular panel cutout. All substitute parts require 7.20mm circular cutouts, which are smaller. Existing panel openings designed for the MPB11106 will accommodate the substitute parts without modification.

Q: Are there differences in mechanical durability between the original and substitute parts?

A: The MPB11106 is rated for 10,000 mechanical and electrical cycles. The E-Switch PS1024 series (both PS1024ALRED and PS1024ARED) are rated for 6,000 cycles. The CW Industries GPB024A05BR does not specify cycle life data. Applications requiring the full 10,000-cycle specification should evaluate this parameter against actual operational requirements.

Q: What is the temperature operating range for each substitute?

A: The original MPB11106 operates from -20°C to 60°C. The E-Switch PS1024 series extends the upper limit to 65°C. The CW Industries GPB024A05BR does not specify operating temperature limits.

Q: Are all substitute parts RoHS compliant?

A: All three substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original MPB11106.

Q: Which substitute should be selected for new designs?

A: Selection should be based on specific application requirements. For applications requiring extended temperature operation, the E-Switch PS1024 series provides -20°C to 65°C coverage. For applications with higher cycle life requirements, the CW Industries GPB024A05BR may be preferred, though cycle life data is not provided. All three parts are active products with established supply availability.
