MPL027 Equivalent & Substitute Parts

Part Overview

The MPL027 is an obsolete pushbutton switch manufactured by Bulgin, classified as a SPST (Single Pole Single Throw) anti-vandal panel mount component. This switch is rated for 2A at 50V AC/DC with a circular 25.80mm panel cutout and solder lug termination. Due to its obsolete product status, identifying functionally compatible substitute parts is necessary for ongoing system maintenance, repair, and new design implementations where equivalent performance characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPL027 is evaluated based on the following critical parameters that define functional equivalence:

Circuit Configuration: Both the main part and substitute must maintain SPST topology to preserve the electrical switching function.

Voltage and Current Ratings: The substitute must meet or exceed the voltage and current specifications of the original part. The MPL027 operates at 2A/50V; substitute parts must support these load conditions.

Mounting and Panel Integration: Panel mount configuration and cutout diameter compatibility are essential for mechanical fit. The MPL027 uses a 25.80mm circular cutout; substitutes must accommodate existing panel installations.

Termination Style: Connection method affects circuit integration. The MPL027 uses solder lug termination; substitutes with different termination styles (such as quick connect) require circuit redesign.

Environmental and Compliance Requirements: RoHS3 compliance and operating temperature range ensure regulatory conformance and operational reliability across the specified temperature envelope.

The PR141C1100 substitute is identified based on matching SPST circuit configuration, panel mount capability, and RoHS3 compliance. However, differences in current rating, voltage specification, termination style, and panel cutout diameter must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The PR141C1100 is an active product with current manufacturing support and RoHS3 compliance, addressing the obsolescence status of the MPL027. Both components share SPST circuit topology and panel mount configuration, establishing baseline functional compatibility.

The PR141C1100 provides enhanced electrical performance with 16A current capacity and 125V AC rating, exceeding the MPL027 specifications. This rating margin accommodates applications with higher load requirements.

Critical considerations for selection:

Termination Compatibility: The PR141C1100 uses quick connect termination (0.250" spade), whereas the MPL027 uses solder lug. Circuit redesign or adapter solutions are required for direct substitution.

Panel Cutout Diameter: The PR141C1100 panel cutout is 25.00mm, compared to the MPL027 at 25.80mm. Existing panel installations may require mechanical modification.

Mounting Method: The PR141C1100 employs snap-in mounting versus the MPL027 front panel mount. Installation procedure and mechanical retention differ.

Operating Temperature: The PR141C1100 supports -20°C to 105°C, providing extended low-temperature performance compared to the MPL027 at -20°C to 70°C.

Selection of the PR141C1100 is appropriate for new designs and applications where circuit redesign and panel modification are feasible. For direct replacement in existing installations with minimal modification, mechanical and electrical interface compatibility must be verified.

Frequently Asked Questions (FAQ)

Q: Can the PR141C1100 directly replace the MPL027 without circuit modification?

A: Direct replacement is not possible without modification. The PR141C1100 uses quick connect termination (0.250" spade) while the MPL027 uses solder lug. Circuit board connections must be redesigned or adapter harnesses implemented.

Q: Are the panel cutout dimensions compatible?

A: No. The MPL027 requires a 25.80mm circular cutout, while the PR141C1100 requires 25.00mm. Existing panels designed for the MPL027 will require enlargement or modification to accommodate the PR141C1100.

Q: Does the PR141C1100 meet the voltage and current requirements of the MPL027 application?

A: The PR141C1100 exceeds the MPL027 specifications, rated at 16A/125V AC versus 2A/50V AC/DC. For applications operating within the MPL027 parameters, the PR141C1100 provides adequate performance margin. DC voltage rating for the PR141C1100 is not specified; applications requiring DC operation must verify compatibility.

Q: What is the difference between anti-vandal and standard pushbutton switches?

A: The MPL027 is classified as anti-vandal, indicating design features for resistance to deliberate damage or tampering. The PR141C1100 is a standard pushbutton switch without anti-vandal specifications. Application environment determines whether this difference is significant.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MPL027 and PR141C1100 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the mechanical life difference between these components?

A: The MPL027 specifies 8,000 mechanical cycles, while the PR141C1100 does not provide mechanical life data. The PR141C1100 electrical life is rated at 10,000 cycles, exceeding the MPL027 at 8,000 cycles.

Q: Can I use the PR141C1100 in applications requiring DC operation?

A: The PR141C1100 is rated for 16A AC at 125V. DC voltage rating is not specified in the provided data. Applications requiring DC operation must obtain complete DC specifications from the manufacturer before selection.
