AM50054D53-A Equivalent & Substitute Parts

Part Overview

The AM50054D53-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 switch features a lever with simulated roller actuator and quick-connect termination suitable for industrial control and safety applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50054D53-A is determined by the following critical parameters:

Circuit Configuration: SPST-NC topology is mandatory for functional equivalence in normally-closed safety and control circuits.

Actuator Type: Lever with simulated roller actuator ensures mechanical compatibility with existing mounting and actuation requirements.

Mounting Type: Chassis mount configuration is required for direct mechanical replacement.

Termination Style: Quick-connect 0.250" (6.3mm) terminals are essential for electrical connection compatibility.

Electrical Ratings: The substitute must support the application's voltage and current requirements. The original part operates at 125V AC / 30V DC with 100mA capacity. Substitutes with equal or higher ratings are acceptable.

Operating Temperature Range: The substitute must cover or exceed the original operating range of -25°C to 105°C.

The Crouzet 83264626 qualifies as a substitute because it maintains the same circuit configuration (SPST-NC), actuator type (lever with simulated roller), mounting type (chassis mount), and termination style (quick-connect 0.250"). Its electrical ratings (250V AC, 12A) exceed the original requirements, providing margin for application safety. The operating temperature range (-20°C to 125°C) covers the original specification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AM50054D53-A is obsolete. The Crouzet 83264626 is active and currently in production, ensuring long-term availability for replacement and future procurement.

Compliance & Certifications: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental handling requirements. The Crouzet part is RoHS Compliant and REACH Unaffected, meeting modern regulatory standards for electronic components.

Electrical Performance: The Crouzet substitute provides higher electrical ratings (250V AC vs. 125V AC; 12A vs. 100mA), which is acceptable for applications designed for the original part. Higher ratings do not compromise functionality in lower-demand circuits.

Mechanical Durability: The original Panasonic part specifies 10,000,000 mechanical cycles versus 1,000,000 cycles for the Crouzet substitute. Applications requiring extended mechanical life should evaluate this difference against actual duty cycle requirements.

Temperature Operating Range: The Crouzet part extends the upper temperature limit to 125°C (versus 105°C), providing additional thermal margin in high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264626 directly replace the AM50054D53-A in existing assemblies?

A: Yes, provided the application does not exceed the Crouzet part's mechanical life specification of 1,000,000 cycles. The electrical ratings, circuit configuration, actuator type, mounting method, and termination style are compatible.

Q: What is the primary reason for substitution?

A: The AM50054D53-A is obsolete. The Crouzet 83264626 is an active product with equivalent functional characteristics and superior electrical ratings.

Q: Are there any mechanical differences between these switches?

A: Both switches use lever actuators with simulated rollers and chassis mounting. Operating force differs (120gf vs. 27gf) and operating position varies slightly (0.730" vs. 0.803"), which may affect mechanical feel and mounting clearances in sensitive applications.

Q: Does the higher current rating of the Crouzet part affect circuit design?

A: No. The Crouzet part's 12A rating exceeds the original 100mA requirement, making it suitable for the same applications. Higher ratings provide design margin without requiring circuit modifications.

Q: What is the temperature operating range difference?

A: The original part operates from -25°C to 105°C. The Crouzet substitute operates from -20°C to 125°C. The Crouzet part has a narrower low-temperature range (-20°C vs. -25°C) but extends the high-temperature limit by 20°C.

Q: Are both parts moisture-resistant?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage or handling.

Q: What compliance certifications apply to the substitute?

A: The Crouzet 83264626 is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components in the European Union and related markets.
