AM50024D53-A Equivalent & Substitute Parts

Part Overview

The AM50024D53-A is a SPST-NC (Single Pole Single Throw - Normally Closed) snap-action switch manufactured by Panasonic Electric Works. This chassis-mounted switch is rated for 100mA at 125V AC and 30V DC, featuring a lever with simulated roller actuator and quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50024D53-A requires matching the following critical parameters:

• Circuit configuration: SPST-NC topology
• Switch function: On-Momentary operation
• Actuator type: Lever with simulated roller
• Mounting interface: Chassis mount
• Termination: Quick Connect 0.250" (6.3mm)
• Electrical ratings: Minimum 100mA current capacity and 125V AC voltage rating

The Crouzet 83264626 qualifies as a functional substitute based on these core parameters. While this substitute exhibits higher electrical ratings (12A at 250V AC) and different mechanical characteristics, it maintains compatibility with the required circuit topology, actuator design, mounting method, and termination standard. The elevated performance specifications of the substitute provide margin for applications within the original part's operational envelope.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264626 is an active product with RoHS compliance and REACH unaffected status, providing supply continuity for applications requiring SPST-NC snap-action switches with lever actuators and chassis mounting. The substitute part exceeds the electrical requirements of the original AM50024D53-A across both current and voltage parameters, ensuring functional compatibility within the original design envelope.

Selection of the Crouzet substitute should be based on application-specific requirements regarding mechanical cycle life expectations and operating temperature range. The original part supports operation to -25°C; the substitute operates to -20°C. The original part is rated for 10,000,000 mechanical cycles; the substitute is rated for 1,000,000 cycles. These differences must be evaluated against actual application demands.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264626 directly replace the AM50024D53-A in existing designs?

A: The Crouzet 83264626 maintains compatibility with the core functional requirements: SPST-NC circuit topology, on-momentary switch function, lever with simulated roller actuator, chassis mounting, and 0.250" quick-connect termination. Physical dimensions and mounting hole patterns must be verified against the original design specifications to confirm mechanical fit.

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

A: The primary differences are electrical ratings (Crouzet rated higher at 12A/250V AC versus Panasonic at 100mA/125V AC), mechanical life expectancy (Panasonic 10,000,000 cycles versus Crouzet 1,000,000 cycles), and operating temperature range (Panasonic -25°C to 105°C versus Crouzet -20°C to 125°C). Both switches share identical circuit topology, actuator type, mounting method, and termination style.

Q: Is the Crouzet part RoHS compliant?

A: Yes, the Crouzet 83264626 is RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What should be verified before implementing the Crouzet substitute?

A: Verify mechanical compatibility including panel cutout dimensions, mounting hole spacing, and actuator travel clearance. Confirm that the application's electrical load does not exceed 100mA at 125V AC (the original part's rating) or that the higher-rated substitute is acceptable. Evaluate whether the reduced mechanical life rating (1,000,000 versus 10,000,000 cycles) aligns with expected product service life and duty cycle.
