AM50054D33-A Equivalent & Substitute Parts

Part Overview

The AM50054D33-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 100mA rating at 125V AC and 30V DC. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support. The lever-actuated design with simulated roller provides reliable mechanical operation across 10,000,000 mechanical cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50054D33-A is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Must be SPST-NC to maintain identical electrical behavior
• Switch Function: Must be On-Mom (momentary) for functional compatibility
• Actuator Type: Must be Lever with Simulated Roller for mechanical interface compatibility
• Mounting Type: Must be Chassis Mount for physical installation compatibility
• Termination Style: Must be Quick Connect - 0.250" (6.3mm) for electrical connection compatibility
• Current and Voltage Ratings: Substitute must meet or exceed the 100mA AC/DC and 125V AC / 30V DC requirements

The Crouzet 83264626 qualifies as a substitute because it maintains identical circuit configuration (SPST-NC), switch function (On-Mom), actuator type (Lever, Simulated Roller), mounting type (Chassis Mount), and termination style (Quick Connect - 0.250"). Its higher current rating (12A AC) and voltage rating (250V AC) provide margin above the original specification, ensuring compatibility in the same application context.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264626 is an active product with RoHS compliance, providing a viable substitute for the obsolete AM50054D33-A. Both switches share identical circuit topology, actuator design, mounting configuration, and termination interface. The Crouzet part exceeds the original electrical specifications with higher current and voltage ratings, ensuring safe operation in applications originally designed for the Panasonic switch.

The primary consideration is mechanical life: the Crouzet part is rated for 1,000,000 cycles compared to the Panasonic's 10,000,000 cycles. For applications requiring extended mechanical cycling beyond 1,000,000 operations, the reduced mechanical life rating must be evaluated against actual duty cycle requirements.

The operating position difference (0.730" vs. 0.803") and operating force difference (30gf vs. 27gf) are minor and fall within typical mechanical tolerance ranges for snap-action switches in this class. Temperature range expansion (-20°C to 125°C vs. -25°C to 105°C) provides additional operational margin.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264626 directly replace the AM50054D33-A in existing applications?

A: Yes, for applications operating within the Crouzet part's mechanical life specification (1,000,000 cycles). Both switches share identical SPST-NC circuit configuration, On-Mom function, lever actuator type, chassis mounting, and Quick Connect termination. The Crouzet part's higher electrical ratings provide compatibility margin.

Q: What is the significance of the mechanical life difference?

A: The AM50054D33-A is rated for 10,000,000 mechanical cycles, while the Crouzet 83264626 is rated for 1,000,000 cycles. Applications requiring operation beyond 1,000,000 cycles should evaluate whether the reduced rating is acceptable for the intended duty cycle.

Q: Are there packaging or form factor differences between these switches?

A: Both switches use identical Quick Connect - 0.250" (6.3mm) termination and chassis mount configuration. The operating position differs slightly (0.730" vs. 0.803"), which may affect mechanical clearance in space-constrained installations. Physical verification is recommended for tight mechanical layouts.

Q: What compliance certifications apply to the substitute part?

A: The Crouzet 83264626 is RoHS Compliant and REACH Unaffected. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification.

Q: Does the operating force difference affect switch performance?

A: The operating force difference is minimal (30gf vs. 27gf, approximately 10% variance). This falls within normal mechanical tolerance ranges for snap-action switches and does not affect functional compatibility in standard applications.
