AM51141C43N-A Equivalent & Substitute Parts

Part Overview

The AM51141C43N-A is a snap action switch manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) device with on-momentary function. This chassis-mounted switch is rated for 11A AC at 125V and 600mA DC at 125V, featuring a straight lever actuator with quick connect termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51141C43N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must be On-Momentary to preserve operational behavior
• Actuator Type: Must be Lever, Straight to ensure mechanical compatibility
• Mounting Type: Must be Chassis Mount for physical installation compatibility
• Termination Style: Must be Quick Connect - 0.187" (4.7mm) for connector compatibility
• Current and Voltage Ratings: Substitute must meet or exceed the 11A AC @ 125V requirement
• Operating Temperature Range: Substitute must cover the operational environment

The Crouzet 83264042 qualifies as a substitute based on these parameters. It maintains SPDT circuit configuration, on-momentary function, lever straight actuator, chassis mount design, and identical quick connect termination. The substitute provides higher voltage rating (250V AC) and comparable current capacity (12A AC), ensuring compatibility with the original application envelope.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264042 is suitable as a substitute for the AM51141C43N-A based on the following factors:

Electrical Compatibility: The substitute meets the minimum current requirement (12A AC exceeds 11A AC) and provides higher voltage rating (250V AC versus 125V AC), ensuring safe operation in the original application circuit.

Mechanical Compatibility: Identical actuator type, mounting configuration, and termination style ensure direct physical replacement without mechanical redesign.

Product Status: The Crouzet part is active in production, providing supply continuity for the obsolete Panasonic component.

Regulatory Compliance: The substitute is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Operational Considerations: The substitute operates across a wider temperature range (-20°C to 125°C versus -25°C to 105°C). The mechanical life rating of the substitute (1,000,000 cycles) is lower than the original (10,000,000 cycles); this difference should be evaluated against the specific duty cycle requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264042 be used as a direct replacement for the AM51141C43N-A?

A: Yes. Both switches share identical circuit configuration (SPDT), switch function (On-Momentary), actuator type (Lever, Straight), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). The Crouzet part meets or exceeds the electrical ratings of the original component.

Q: What are the key differences between these two switches?

A: The primary differences are voltage rating (Crouzet rated for 250V AC versus Panasonic 125V AC), mechanical life (Crouzet 1,000,000 cycles versus Panasonic 10,000,000 cycles), and operating temperature range (Crouzet -20°C to 125°C versus Panasonic -25°C to 105°C). The Crouzet part is RoHS Compliant; the Panasonic compliance status is not specified.

Q: Will the quick connect termination fit without modification?

A: Yes. Both switches use identical Quick Connect - 0.187" (4.7mm) termination, allowing direct connection to existing harnesses and connectors without modification.

Q: Is the lower mechanical life rating of the Crouzet part a concern?

A: The mechanical life difference should be evaluated based on the specific application duty cycle. If the application requires fewer than 1,000,000 actuations over the product lifetime, the Crouzet part is suitable. Applications requiring higher cycle counts should be reassessed for component selection.

Q: Are there any compliance or certification differences?

A: The Crouzet 83264042 is RoHS Compliant and REACH Unaffected. The Panasonic AM51141C43N-A compliance status for these standards is not specified in the available data. Both parts carry EAR99 ECCN classification.
