AM50056C43-A Equivalent & Substitute Parts

Part Overview

The AM50056C43-A is a SPST-NC (Single Pole Single Throw - Normally Closed) snap-action switch manufactured by Panasonic Electric Works. This chassis-mounted switch is designed for low-current applications with a rated capacity of 100mA at 125V AC and 30V DC. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50056C43-A is determined by the following critical parameters:

Circuit Configuration Match: The substitute must maintain SPST-NC topology to preserve the normally-closed contact behavior required by the original design.

Switch Function Match: The substitute must retain On-Mom (momentary) operation to ensure identical user interaction and control logic.

Mounting and Termination Compatibility: Chassis mount configuration with Quick Connect - 0.187" (4.7mm) termination ensures mechanical and electrical interface compatibility.

Actuator Type Compatibility: Lever and roller actuator types are functionally interchangeable within this product category.

Electrical Performance Envelope: The substitute must meet or exceed the original voltage and current ratings to ensure safe operation within the design's electrical constraints.

The Crouzet 83265647 satisfies all primary substitution criteria through matching circuit configuration (SPST-NC), switch function (On-Mom), mounting type (Chassis Mount), termination style (Quick Connect - 0.187"), and actuator type (Lever, Roller).

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265647 is functionally equivalent to the AM50056C43-A for applications requiring SPST-NC momentary switch operation with chassis mount configuration and Quick Connect termination.

Electrical Compatibility: The Crouzet substitute exceeds the original voltage rating (250V AC vs. 125V AC) and current capacity (5A vs. 100mA), providing margin for the original application's electrical requirements.

Mechanical Compatibility: Operating position and actuator geometry are substantially equivalent (0.806" vs. 0.815"), ensuring compatibility with existing mechanical interfaces and enclosure designs.

Product Status Advantage: The Crouzet part is active in production, eliminating obsolescence risk and ensuring long-term availability for procurement and field replacement.

Compliance Status: The Crouzet 83265647 carries RoHS Compliance and REACH Unaffected certifications, meeting modern regulatory requirements for electronic components.

Operational Considerations: The Crouzet substitute exhibits lower operating and release forces (25gf and 5.099gf respectively) compared to the original (60gf and 10gf), which may affect tactile feedback and actuation characteristics in user-facing applications.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265647 directly replace the AM50056C43-A in existing designs?

A: Yes, for applications operating within the original electrical specifications (100mA, 125V AC, 30V DC). The matching circuit configuration (SPST-NC), switch function (On-Mom), mounting type (Chassis Mount), termination style (Quick Connect - 0.187"), and actuator type (Lever, Roller) ensure mechanical and electrical interface compatibility.

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

A: The primary differences are current rating (5A vs. 100mA), AC voltage rating (250V vs. 125V), operating force (25gf vs. 60gf), release force (5.099gf vs. 10gf), mechanical life (1,000,000 vs. 10,000,000 cycles), and product status (Active vs. Obsolete). The Crouzet part provides higher electrical capacity and modern compliance certifications.

Q: Will the lower operating force of the Crouzet switch affect my application?

A: The Crouzet 83265647 requires less force to actuate (25gf vs. 60gf) and release (5.099gf vs. 10gf). This difference may be noticeable in manual control applications where tactile feedback or deliberate actuation force is a design requirement. Evaluate your specific application's force requirements before substitution.

Q: Is the Crouzet 83265647 RoHS compliant?

A: Yes, the Crouzet 83265647 is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the mechanical life difference, and does it matter?

A: The AM50056C43-A has a mechanical life of 10,000,000 cycles, while the Crouzet 83265647 is rated for 1,000,000 cycles. For applications with high-frequency actuation cycles, this tenfold difference may impact component longevity and replacement intervals.

Q: Are the operating positions compatible?

A: Yes, the operating positions are substantially equivalent (0.806" for Crouzet vs. 0.815" for Panasonic), representing a difference of only 0.009 inches (0.2mm). This minimal variance ensures compatibility with existing mechanical interfaces and enclosure designs.
