AM51164D43N-A Equivalent & Substitute Parts

Part Overview

The AM51164D43N-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 600mA DC at 125V, featuring a lever with simulated roller actuator and quick connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued operation is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM51164D43N-A is determined by strict alignment of the following critical parameters:

Circuit & Function Compatibility:

• Circuit configuration must remain SPST-NO
• Switch function must be Off-Mom (momentary operation)

Electrical Ratings:

• AC current rating must meet or exceed 11A
• AC voltage rating must meet or exceed 125V
• Termination style must be Quick Connect - 0.250" (6.3mm)

Mechanical & Physical:

• Actuator type must be Lever with Simulated Roller
• Mounting type must be Chassis Mount
• Operating temperature range must encompass the original -25°C to 105°C specification or provide equivalent thermal performance

Environmental & Compliance:

• Cadmium-free construction required
• Moisture Sensitivity Level (MSL) must be 1 (Unlimited) or equivalent

The Crouzet 83264826 qualifies as a substitute based on these parameters: it maintains SPST-NO circuit configuration, Off-Mom function, lever simulated roller actuator, chassis mount, and quick connect 0.250" termination. Its 12A AC rating at 250V exceeds the original electrical requirements, and its -20°C to 125°C operating range encompasses the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264826 is suitable as a substitute for the obsolete AM51164D43N-A based on the following factors:

Functional Equivalence: Both switches maintain identical circuit configuration (SPST-NO) and switch function (Off-Mom), ensuring direct functional replacement in momentary control applications.

Electrical Superiority: The Crouzet part exceeds electrical requirements with 12A AC at 250V, compared to the original 11A at 125V. This provides margin for system reliability.

Mechanical Compatibility: Identical actuator type (lever, simulated roller), mounting method (chassis mount), and termination style (quick connect 0.250") ensure physical and electrical interface compatibility.

Product Status & Availability: The Crouzet 83264826 is active in production with 940 units in stock, providing supply continuity for the obsolete Panasonic part.

Compliance Considerations: The Crouzet part is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements. The original part's cadmium-free specification is matched by the Crouzet alternative.

Operational Differences: The Crouzet part exhibits lower operating force (27gf vs. 60gf) and reduced mechanical life (1,000,000 vs. 10,000,000 cycles). These differences should be evaluated against specific application requirements. The extended operating temperature range (-20°C to 125°C) of the Crouzet part provides additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264826 directly replace the AM51164D43N-A in existing applications?

A: Yes, for applications requiring SPST-NO momentary switch function with chassis mount and quick connect 0.250" termination. The Crouzet part meets or exceeds all critical electrical and mechanical parameters. However, the lower operating force and reduced mechanical life cycle rating should be verified against specific application demands before implementation.

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

A: The primary differences are operating force (27gf vs. 60gf), mechanical life rating (1,000,000 vs. 10,000,000 cycles), and operating position (0.803" vs. 0.730"). The Crouzet part provides higher voltage and current ratings (250V/12A vs. 125V/11A) and an extended upper operating temperature limit (125°C vs. 105°C).

Q: Are there any compatibility concerns with the quick connect termination?

A: No. Both switches use identical quick connect 0.250" (6.3mm) termination, ensuring direct electrical and mechanical interface compatibility without modification.

Q: Does the lower operating force of the Crouzet switch affect functionality?

A: The Crouzet switch requires less force to actuate (27gf vs. 60gf). This may affect tactile feedback and operator perception but does not impact electrical function. Applications sensitive to actuation force should be evaluated individually.

Q: What is the significance of the mechanical life difference?

A: The AM51164D43N-A is rated for 10,000,000 mechanical cycles, while the Crouzet 83264826 is rated for 1,000,000 cycles. For high-cycle applications, the original specification should be compared against actual duty cycle requirements to determine if the Crouzet part is suitable.

Q: Are both switches RoHS compliant?

A: The Crouzet 83264826 is explicitly RoHS Compliant. The AM51164D43N-A compliance status is not specified in the provided data. Both are cadmium-free and MSL 1 rated.

Q: Can the Crouzet part be used in DC applications?

A: The provided specifications for the Crouzet 83264826 do not include DC current rating data. The original AM51164D43N-A is rated for 600mA DC at 125V. DC compatibility of the Crouzet part should be confirmed through manufacturer documentation before use in DC circuits.
