AM51160C43N-A Equivalent & Substitute Parts

Part Overview

The AM51160C43N-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 equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51160C43N-A is determined by the following critical parameters:

Circuit Configuration: SPST-NO topology is mandatory for functional equivalence.

Actuator Type: Round pin plunger actuator ensures mechanical compatibility with existing mounting interfaces.

Mounting Type: Chassis mount configuration is required for installation compatibility.

Termination Style: Quick connect 0.187" (4.7mm) terminals are essential for electrical connection compatibility.

Electrical Ratings: The substitute must meet or exceed the AC current rating of 11A and AC voltage rating of 125V to ensure safe operation in the original application circuit.

Switch Function: Off-Mom (momentary) operation must be preserved for functional equivalence.

The Crouzet 83264841 qualifies as a substitute based on matching circuit configuration (SPST-NO), actuator type (round pin plunger), mounting type (chassis mount), termination style (quick connect 0.187"), and switch function (Off-Mom). The Crouzet part exceeds the electrical ratings of the original component with 12A AC at 250V, providing enhanced electrical capacity for the application.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264841 is suitable as a substitute for the obsolete AM51160C43N-A based on the following engineering criteria:

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 functional replacement in the original application.

Electrical Capacity: The Crouzet part provides higher electrical ratings (12A AC at 250V) compared to the original (11A AC at 125V), ensuring safe operation in circuits designed for the lower-rated Panasonic component.

Product Status: The Crouzet 83264841 is active in production, providing long-term availability for replacement and maintenance applications.

Compliance: The Crouzet part is RoHS Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Mechanical Characteristics: Operating position (0.579"), differential travel (0.016"), and mounting interface are identical, ensuring drop-in compatibility without mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264841 directly replace the AM51160C43N-A in existing applications?

A: Yes. Both switches share identical circuit configuration (SPST-NO), actuator type (round pin plunger), mounting type (chassis mount), termination style (quick connect 0.187"), and switch function (Off-Mom). The Crouzet part meets or exceeds all electrical ratings of the original component.

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

A: The primary differences are electrical ratings and mechanical life. The Crouzet 83264841 provides higher AC voltage rating (250V vs. 125V) and higher AC current rating (12A vs. 11A). The Panasonic AM51160C43N-A has longer mechanical life (10,000,000 cycles vs. 1,000,000 cycles). Both switches maintain identical operating position, differential travel, and termination compatibility.

Q: Are there any compliance or certification differences?

A: The Crouzet 83264841 is RoHS Compliant and REACH Unaffected. The Panasonic AM51160C43N-A is cadmium free. Both parts carry EAR99 ECCN classification. The Crouzet part meets current regulatory requirements for new component procurement.

Q: What is the operating temperature range difference?

A: The Panasonic AM51160C43N-A operates from -25°C to 105°C. The Crouzet 83264841 operates from -20°C to 125°C. For applications requiring operation below -20°C, the Panasonic part is required. For applications requiring operation above 105°C, the Crouzet part is required.

Q: How do the mechanical life ratings compare?

A: The Panasonic AM51160C43N-A is rated for 10,000,000 mechanical cycles. The Crouzet 83264841 is rated for 1,000,000 mechanical cycles. For high-cycle applications, the Panasonic specification is superior. For typical industrial applications, the Crouzet rating is adequate.

Q: Are the quick connect terminals identical?

A: Yes. Both switches use quick connect 0.187" (4.7mm) termination style, ensuring electrical connection compatibility without modification to existing harnesses or PCB layouts.
