MSPS103C0 Equivalent & Substitute Parts

Part Overview

The MSPS103C0 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Standard Panel Mount SPST-NO (Single Pole Single Throw - Normally Open) switch with momentary off function. The switch is rated for 500mA at 125V AC and features a circular black button actuator with solder lug termination. This part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSPS103C0 is based on strict electrical and mechanical compatibility criteria. The following parameters must align for a component to function as a direct substitute:

Critical Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Voltage rating: 125V AC minimum
• Current rating: Equal to or greater than 500mA
• Mounting type: Panel Mount, Rear
• Actuator type: Round, Button
• Termination style: Solder Lug
• Panel cutout dimensions: Compatible with 6.35mm circular opening or smaller

The GPB024A05BB from CW Industries meets these substitution criteria with the exception of panel cutout diameter, which is specified at 7.20mm. This larger cutout dimension requires mechanical accommodation during installation but does not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

The GPB024A05BB from CW Industries is the identified substitute for the obsolete MSPS103C0. Selection of this substitute is supported by the following factors:

Electrical Compatibility: The GPB024A05BB maintains identical circuit configuration (SPST-NO), switch function (Off-Mom), and voltage rating (125V AC). The current rating of 3A exceeds the original 500mA requirement, providing operational margin within the same electrical class.

Mechanical Compatibility: Both switches feature identical mounting type (Panel Mount, Rear), actuator type (Round, Button), actuator color (Black), and termination style (Solder Lug). The panel cutout diameter difference (7.20mm versus 6.35mm) requires panel modification but does not affect electrical performance or switch operation.

Product Status and Compliance: The GPB024A05BB is classified as Active production status, ensuring ongoing availability and supply chain continuity. The substitute meets ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for new designs and system updates.

Moisture Sensitivity: Both components share identical MSL rating of 1 (Unlimited), indicating equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the GPB024A05BB directly replace the MSPS103C0 without any modifications?

A: Electrical and functional replacement is direct. Mechanical installation requires panel cutout enlargement from 6.35mm to 7.20mm diameter to accommodate the substitute switch body.

Q: What is the significance of the higher current rating (3A) on the GPB024A05BB compared to the 500mA rating of the MSPS103C0?

A: The higher current rating indicates the substitute switch is rated for greater electrical load capacity. In applications requiring only 500mA, the substitute operates well within its rated specifications, providing additional safety margin and component longevity.

Q: Are there any differences in operating temperature ranges between these two switches?

A: The MSPS103C0 specifies an operating temperature range of -20°C to 80°C. The GPB024A05BB does not provide operating temperature specification in the available data. Thermal performance should be evaluated for applications with temperature extremes outside standard room conditions.

Q: What does the panel cutout dimension difference mean for installation?

A: The MSPS103C0 requires a 6.35mm circular panel opening, while the GPB024A05BB requires a 7.20mm circular opening. Existing panel cutouts designed for the original part must be enlarged by approximately 0.85mm in diameter to accommodate the substitute switch.

Q: Is the GPB024A05BB suitable for new designs?

A: Yes. The GPB024A05BB is classified as Active production status and meets current compliance standards (ROHS3 Compliant, REACH Unaffected). It is suitable for new design implementations requiring SPST-NO momentary pushbutton switches at 125V AC.

Q: How do the electrical life specifications compare?

A: The MSPS103C0 specifies 10,000 electrical cycles. The GPB024A05BB does not provide electrical life specification in the available data. For applications with specific cycle life requirements, this parameter should be obtained from the manufacturer.

Q: Are the solder lug terminations compatible with existing circuit board designs?

A: Both switches feature solder lug termination style, indicating compatibility with standard solder lug connection methods. Existing circuit board designs and wiring harnesses designed for solder lug connections are compatible with the substitute.
