AM51135C43N-A Equivalent & Substitute Parts
Part Overview
The AM51135C43N-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 and quick connect 0.187" termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Engineering Selection Recommendations
The Crouzet 83264847 is a direct functional equivalent for the obsolete Panasonic AM51135C43N-A based on the following engineering criteria:
Circuit and Mechanical Compatibility: Both switches are SPST-NO momentary devices with identical actuator types (lever-roller), chassis mount configuration, and quick connect 0.187" termination. Operating positions are within 0.009" (0.2mm) of each other, ensuring mechanical interchangeability in standard chassis cutout applications.
Electrical Performance: The Crouzet substitute exceeds the original part's electrical ratings, providing 12A AC at 250V compared to the original 11A AC at 125V. This higher rating ensures safe operation in the original application envelope.
Product Status and Availability: The Crouzet part is actively manufactured and in stock (1006 units available), providing supply chain continuity for the obsolete Panasonic component. The substitute carries RoHS Compliance and REACH Unaffected certifications, meeting current regulatory requirements.
Temperature Operating Range: The Crouzet substitute operates across -20°C to 125°C, which encompasses the original part's -25°C to 105°C range for most industrial applications. Applications requiring operation below -20°C require verification against specific system requirements.
Frequently Asked Questions (FAQ)
Q: Can the Crouzet 83264847 be used as a direct replacement for the Panasonic AM51135C43N-A?
A: Yes. Both switches share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (lever-roller), mounting type (chassis mount), and termination style (quick connect 0.187"). Operating positions differ by only 0.009", ensuring mechanical compatibility in standard applications.
Q: What are the key electrical differences between these switches?
A: The Crouzet substitute is rated for 12A AC at 250V, exceeding the original part's 11A AC at 125V specification. This higher rating provides additional safety margin in the original application. DC voltage rating for the Crouzet part is not specified in available documentation.
Q: Are there any temperature range limitations when substituting?
A: The Crouzet substitute operates from -20°C to 125°C, compared to the original -25°C to 105°C. For applications requiring operation below -20°C, verify that system requirements fall within the substitute's specified range.
Q: What certifications does the substitute part carry?
A: The Crouzet 83264847 is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards. Both parts carry EAR99 ECCN classification.
Q: How do the mechanical life ratings compare?
A: The original Panasonic part specifies 10,000,000 mechanical cycles. The Crouzet substitute specifies 1,000,000 mechanical cycles. For applications requiring extended mechanical life, verify that the substitute's rating meets system requirements.
Q: Are the quick connect terminals identical?
A: Yes. Both switches use quick connect 0.187" (4.7mm) termination, ensuring direct compatibility with existing harnesses and connectors without modification.
