AM51131C43N-A Equivalent & Substitute Parts

Part Overview

The AM51131C43N-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 straight lever actuator and quick connect termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51131C43N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical function
• Switch Function: Must be Off-Mom (momentary action)
• Mounting Type: Must be Chassis Mount for mechanical compatibility
• Termination Style: Must be Quick Connect - 0.187" (4.7mm) for direct connection compatibility
• Actuator Type: Must be Lever, Straight for operational consistency
• Current and Voltage Ratings: Substitute must meet or exceed the 11A AC @ 125V requirement to ensure safe operation in the original application

The Crouzet 83264842 qualifies as a substitute based on matching circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Chassis Mount), termination style (Quick Connect - 0.187"), and actuator type (Lever, Straight). The substitute provides higher current capacity (12A AC) and voltage rating (250V AC), ensuring compatibility with the original application parameters.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264842 is a qualified substitute for the obsolete AM51131C43N-A based on matching electrical circuit configuration, mechanical mounting interface, and termination compatibility. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The Crouzet 83264842 provides electrical performance that exceeds the original specification: 12A AC capacity versus 11A AC, and 250V AC rating versus 125V AC. These higher ratings ensure the substitute will operate safely within the original application's electrical requirements.

The operating temperature range of the Crouzet part (-20°C to 125°C) encompasses the original specification range (-25°C to 105°C) with the exception of the lower temperature limit, which is 5°C higher. For applications requiring operation below -20°C, thermal performance verification is necessary.

The mechanical life rating of the Crouzet part (1,000,000 cycles) is lower than the original (10,000,000 cycles). For high-cycle applications, this difference should be evaluated against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264842 be used as a direct replacement for the AM51131C43N-A?

A: Yes, the Crouzet 83264842 qualifies as a substitute. Both parts share identical circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Chassis Mount), termination style (Quick Connect - 0.187"), and actuator type (Lever, Straight). The Crouzet part provides equal or higher electrical ratings, ensuring compatibility with the original application.

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

A: The primary differences are: (1) Current capacity: Crouzet provides 12A AC versus 11A AC for the original; (2) Voltage rating: Crouzet is rated 250V AC versus 125V AC; (3) Operating force: Crouzet requires 51gf versus 110gf for the original; (4) Mechanical life: Crouzet is rated for 1,000,000 cycles versus 10,000,000 cycles; (5) Product status: Crouzet is active production versus obsolete.

Q: Will the Crouzet part fit in the same mounting location?

A: Yes. Both parts are chassis mount with identical termination style (Quick Connect - 0.187"). Operating position measurements are nearly identical (0.602" versus 0.606"), confirming mechanical compatibility.

Q: Are there any compliance or certification differences?

A: The Crouzet 83264842 is RoHS Compliant and REACH Unaffected. Both parts carry EAR99 ECCN classification and have MSL rating of 1 (Unlimited). The original AM51131C43N-A is noted as Cadmium Free.

Q: What should be considered before implementing this substitution?

A: Verify that the application's actual operating temperature range does not require operation below -20°C. Confirm that the mechanical life requirement of 1,000,000 cycles is sufficient for the intended duty cycle. Both parts meet the electrical requirements of the original application.
