AM50654D33-A Equivalent & Substitute Parts

Part Overview

The AM50654D33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device with a 6A AC / 500mA DC current rating at 125V. The switch features a lever with simulated roller actuator and chassis mount termination using quick connect 0.250" (6.3mm) terminals. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50654D33-A is determined by the following critical parameters:

• Circuit Configuration: SPST-NC topology must be maintained
• Switch Function: On-Mom (momentary) operation required
• Actuator Type: Lever with simulated roller mechanism
• Mounting Type: Chassis mount configuration
• Termination Style: Quick connect 0.250" (6.3mm) terminals
• Electrical Ratings: Current and voltage capacity must meet or exceed application requirements
• Operating Temperature: Functional range must encompass the application environment
• Mechanical Durability: Cycle life must support intended duty cycle

The Crouzet 831613B3.FB satisfies these substitution criteria. It maintains identical circuit topology (SPST-NC), switch function (On-Mom), actuator configuration (lever with simulated roller), mounting method (chassis mount), and termination style (quick connect 0.250"). The substitute part exceeds the electrical performance of the original, with 16A AC @ 250V capacity compared to 6A AC @ 125V, and provides superior mechanical life (20,000,000 cycles versus 10,000,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 831613B3.FB is a direct functional substitute for the obsolete AM50654D33-A. Both switches share identical circuit topology, actuator mechanism, mounting configuration, and termination style. The Crouzet part is currently in active production status, ensuring long-term availability and supply chain continuity.

The Crouzet substitute provides enhanced electrical performance with 16A AC @ 250V capacity, exceeding the original 6A AC @ 125V specification. This increased rating provides design margin for applications operating at or near the original part's limits. Mechanical life is doubled (20,000,000 cycles), supporting extended service intervals or higher-duty applications.

The Crouzet 831613B3.FB carries RoHS compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The operating temperature range extends to 125°C, providing broader environmental compatibility compared to the original 105°C maximum.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831613B3.FB directly replace the AM50654D33-A in existing assemblies?

A: Yes. Both switches share identical SPST-NC circuit configuration, On-Mom switch function, lever with simulated roller actuator, chassis mount configuration, and quick connect 0.250" (6.3mm) termination. Physical and electrical interfaces are compatible. The Crouzet part's higher current and voltage ratings do not create incompatibility; they provide additional performance margin.

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

A: The primary differences are current rating (16A versus 6A AC), voltage rating (250V versus 125V AC), mechanical life (20,000,000 versus 10,000,000 cycles), maximum operating temperature (125°C versus 105°C), and product status (active versus obsolete). The Crouzet part exceeds all electrical and mechanical specifications of the original.

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

A: No. Higher current capacity does not require circuit modifications. The substitute part operates identically to the original within the original application's current and voltage parameters. The increased rating provides design margin and does not introduce compatibility issues.

Q: Are there any packaging or mounting considerations?

A: Both switches use identical chassis mount configuration and quick connect 0.250" (6.3mm) termination. No mechanical redesign or panel modifications are required for substitution.

Q: What certifications does the Crouzet substitute carry?

A: The Crouzet 831613B3.FB is RoHS compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement and environmental compliance.
