AM51136D43N-A Equivalent & Substitute Parts

Part Overview

The AM51136D43N-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 termination. This switch is rated for 11A AC at 125V and 600mA DC at 125V, featuring a lever roller actuator with quick connect 0.250" (6.3mm) termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51136D43N-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Actuator type: Lever with roller mechanism
• Mounting type: Chassis mount
• Termination style: Quick connect 0.250" (6.3mm)

Electrical Compatibility Criteria:

• AC current rating must meet or exceed 11A
• AC voltage rating must meet or exceed 125V
• Mechanical and electrical life specifications must support intended application duty cycle

The Crouzet 83264827 satisfies all primary compatibility criteria. It maintains identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (lever roller), mounting type (chassis mount), and termination style (quick connect 0.250"). Electrically, it exceeds the AM51136D43N-A requirements with 12A AC at 250V rating, providing margin for higher voltage applications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264827 is a qualified substitute for the AM51136D43N-A based on functional and electrical equivalence. The substitute part maintains all critical interface parameters (circuit, function, actuator, mounting, and termination) while providing enhanced electrical ratings (12A AC at 250V versus 11A AC at 125V).

The Crouzet part carries active product status and RoHS compliance certification, supporting long-term availability and regulatory alignment. The operating temperature range of -20°C to 125°C encompasses the original part's -25°C to 105°C specification, with the exception of the lower temperature limit (5°C difference). The mechanical life rating of 1,000,000 cycles is lower than the original 10,000,000 cycles; this difference must be evaluated against actual application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264827 directly replace the AM51136D43N-A in existing assemblies?

A: Yes, provided the application duty cycle does not exceed 1,000,000 mechanical cycles. The substitute maintains identical mounting, termination, and functional characteristics. Physical dimensions are equivalent (operating position 0.806" versus 0.815").

Q: What is the significance of the lower operating force in the Crouzet part (51gf versus 60gf)?

A: The Crouzet part requires 9gf less force to actuate. This affects operator feel and may impact applications with mechanical linkages or force-sensitive actuation systems. Both parts maintain identical 10gf release force.

Q: Does the Crouzet part support the full temperature range of the original?

A: The Crouzet part operates from -20°C to 125°C, compared to the original -25°C to 105°C. The lower temperature limit is 5°C higher. Applications requiring operation below -20°C must retain the original Panasonic part.

Q: What is the impact of the 9,000,000 cycle difference in mechanical life?

A: The Crouzet part is rated for 1,000,000 mechanical cycles versus 10,000,000 for the original. Applications with high-cycle momentary switching must verify that actual duty cycle does not exceed the substitute's rating.

Q: Is the Crouzet part RoHS compliant?

A: Yes, the Crouzet 83264827 is RoHS compliant. The original AM51136D43N-A RoHS status is not specified in available documentation.

Q: Are there any differences in electrical performance between these parts?

A: The Crouzet part exceeds the original in AC voltage rating (250V versus 125V) and current rating (12A versus 11A). Both are SPST-NO momentary switches with identical quick connect 0.250" termination. DC rating information is not provided for the Crouzet part.
