AM51130C43N-A Equivalent & Substitute Parts

Part Overview

The AM51130C43N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with chassis mount installation. This switch is rated for 11A AC at 125V and features a round pin plunger actuator with quick connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51130C43N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical behavior
• Switch Function: Must be Off-Mom (momentary action)
• Actuator Type: Must be round pin plunger for mechanical compatibility
• Mounting Type: Must be chassis mount for installation compatibility
• Termination Style: Must be quick connect 0.187" (4.7mm) for electrical connection compatibility
• Voltage and Current Ratings: Substitute must meet or exceed the 11A AC @ 125V requirement
• Operating Temperature Range: Should accommodate the -25°C to 105°C specification

The Crouzet 83264841 qualifies as a substitute based on matching circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (round pin plunger), mounting type (chassis mount), and termination style (quick connect 0.187"). The substitute provides enhanced voltage rating (250V AC) and current capacity (12A AC), ensuring compatibility in the original application while offering improved electrical margins.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264841 is suitable as a substitute for the obsolete AM51130C43N-A based on the following factors:

Functional Compatibility: Both switches share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (round pin plunger), mounting type (chassis mount), and termination style (quick connect 0.187"). These parameters ensure direct mechanical and electrical interchangeability in the original application.

Electrical Performance: The Crouzet substitute provides 12A AC current capacity at 250V, exceeding the original 11A AC @ 125V specification. This enhanced rating ensures the substitute operates within safe electrical margins in the original circuit.

Product Availability: The Crouzet 83264841 is currently active in production, providing reliable long-term sourcing compared to the obsolete Panasonic part.

Compliance Status: The Crouzet substitute is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements.

Operational Considerations: The substitute operates across -20°C to 125°C, covering the original -25°C to 105°C range with extended upper temperature capability. Mechanical life rating of 1,000,000 cycles is lower than the original 10,000,000 cycles; application duty cycle should be evaluated to confirm adequacy.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264841 directly replace the AM51130C43N-A in existing assemblies?

A: Yes. Both switches share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (round pin plunger), mounting type (chassis mount), and termination style (quick connect 0.187"). Direct mechanical and electrical substitution is possible without circuit modification.

Q: What are the key differences between these switches?

A: The primary differences are voltage rating (250V vs. 125V), current capacity (12A vs. 11A AC), operating temperature range (-20°C to 125°C vs. -25°C to 105°C), and mechanical life (1,000,000 vs. 10,000,000 cycles). The Crouzet substitute provides higher electrical ratings and extended upper temperature range.

Q: Is the mechanical life difference significant?

A: The Crouzet substitute has a lower mechanical life rating (1,000,000 cycles vs. 10,000,000 cycles). Substitution is appropriate for applications with moderate duty cycles. High-frequency switching applications should evaluate whether the lower cycle rating meets operational requirements.

Q: Are there compliance or certification differences?

A: The Crouzet 83264841 is RoHS Compliant and REACH Unaffected. The original Panasonic part is obsolete and no longer subject to modern compliance verification. The substitute meets current regulatory standards.

Q: What is the temperature operating range difference?

A: The Crouzet substitute operates from -20°C to 125°C, compared to the original -25°C to 105°C. The substitute covers the original range with extended upper temperature capability but has a slightly higher minimum operating temperature (-20°C vs. -25°C).

Q: Are the quick connect terminations identical?

A: Yes. Both switches use quick connect 0.187" (4.7mm) termination style, ensuring compatible connection to existing harnesses and PCB receptacles without modification.
