AM51133D43N-A Equivalent & Substitute Parts

Part Overview

The AM51133D43N-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 equivalent substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51133D43N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Actuator type must be lever with straight configuration
• Mounting type must be chassis mount
• Termination style must be quick connect 0.250" (6.3mm)
• Current rating must meet or exceed 11A AC at the operating voltage
• Voltage rating must support minimum 125V AC operation
• Operating temperature range must encompass or exceed -25°C to 105°C

The Crouzet 83264823 satisfies these substitution criteria. While it operates at a higher voltage rating (250V AC) and current capacity (12A AC), these represent enhanced electrical specifications that maintain backward compatibility with the original application parameters. The mechanical and functional characteristics—lever actuator, chassis mount configuration, quick connect termination, and momentary operation—are identical to the original part.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264823 is a direct functional substitute for the AM51133D43N-A. The substitute part maintains identical circuit topology (SPST-NO), actuator configuration (straight lever), mounting method (chassis mount), and termination interface (0.250" quick connect). Current and voltage ratings of the Crouzet part exceed the original specification, providing enhanced electrical capacity within the same mechanical envelope.

The Crouzet 83264823 holds active product status with RoHS compliance and REACH unaffected designation, ensuring availability and regulatory alignment for new installations and ongoing production support. The original Panasonic part, classified as obsolete, presents sourcing constraints for replacement and repair applications.

Selection of the Crouzet substitute is appropriate for applications requiring direct mechanical and electrical compatibility with the AM51133D43N-A footprint and interface specifications.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264823 be used as a direct replacement for the AM51133D43N-A?

A: Yes. Both switches share identical SPST-NO circuit configuration, momentary operation, straight lever actuator, chassis mount installation, and 0.250" quick connect termination. The Crouzet part operates at higher voltage and current ratings, which are compatible with applications designed for the original 125V, 11A specification.

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

A: Both switches feature identical actuator type (straight lever) and mounting configuration (chassis mount). Operating position measurements differ slightly (0.602" vs 0.606"), representing negligible variation within standard mechanical tolerance. Differential travel specifications differ (0.080" vs 0.031"), reflecting design variations in contact engagement characteristics.

Q: Does the higher voltage rating of the Crouzet part affect compatibility?

A: No. The Crouzet 83264823 is rated for 250V AC operation, exceeding the 125V requirement of the original application. This enhanced rating does not compromise functionality in circuits designed for 125V operation and provides additional safety margin.

Q: Are there compliance or certification differences?

A: The Crouzet 83264823 carries RoHS compliance and REACH unaffected status, meeting current regulatory requirements. The original Panasonic part, being obsolete, may not meet current environmental and safety standards for new applications.

Q: What is the mechanical life difference between these parts?

A: The AM51133D43N-A specifies 10,000,000 mechanical cycles, while the Crouzet 83264823 specifies 1,000,000 cycles. For applications requiring extended mechanical life, this difference should be evaluated against actual duty cycle requirements.
