AM50653C33-A Equivalent & Substitute Parts

Part Overview

The AM50653C33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device with on-momentary function. This chassis-mount switch is rated for 6A at 125V AC and features a straight lever actuator with quick-connect 0.187" (4.7mm) termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50653C33-A requires matching the following critical parameters:

Circuit configuration must remain SPST-NC with on-momentary function to preserve electrical behavior in the application. The actuator type (lever, straight) and mounting method (chassis mount) must be identical to ensure mechanical compatibility with existing enclosures and control panels. Termination style must match the quick-connect 0.187" (4.7mm) standard to allow direct connection without adapter hardware.

Current and voltage ratings establish the operational envelope. The substitute part must support at minimum the AC current rating of 6A and AC voltage rating of 125V specified for the original component. The operating temperature range and lifecycle ratings (electrical and mechanical cycles) define reliability expectations under specified conditions.

The Crouzet 831607B6.A satisfies these substitution criteria: it maintains SPST-NC circuit configuration with on-momentary function, features identical lever-straight actuator and chassis-mount design, and uses the same quick-connect 0.187" (4.7mm) termination. The substitute exceeds the voltage rating requirement at 250V AC, providing margin for higher-voltage applications. Both parts share identical electrical lifecycle (100,000 cycles) and mechanical lifecycle (10,000,000 cycles) specifications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 831607B6.A is a direct functional equivalent for the obsolete Panasonic AM50653C33-A. Both components share identical circuit topology, actuator geometry, mounting interface, and termination standard. The Crouzet substitute maintains active product status, ensuring ongoing availability and technical support.

The 831607B6.A provides enhanced voltage rating (250V AC versus 125V AC), which accommodates applications requiring higher voltage margins without circuit modification. Both parts carry identical REACH Unaffected and EAR99 export classification status, maintaining regulatory compliance across jurisdictions.

Mechanical and electrical lifecycle specifications are equivalent between the two parts, supporting identical duty-cycle applications. Moisture sensitivity classification (MSL 1) is identical, indicating no special handling or storage requirements for either component.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831607B6.A directly replace the Panasonic AM50653C33-A without modification?

A: Yes. Both switches share identical SPST-NC circuit configuration, on-momentary function, lever-straight actuator, chassis-mount design, and quick-connect 0.187" (4.7mm) termination. No circuit or mechanical modifications are required.

Q: What is the significance of the higher voltage rating on the Crouzet substitute?

A: The Crouzet part is rated for 250V AC compared to the Panasonic part's 125V AC rating. This higher rating provides operational margin in applications approaching the original voltage specification and enables use in higher-voltage systems without component change.

Q: Are there any compliance or export restrictions affecting either part?

A: Both the Panasonic AM50653C33-A and Crouzet 831607B6.A carry identical REACH Unaffected status and EAR99 export classification. No additional compliance documentation is required for substitution.

Q: How do the lifecycle specifications compare?

A: Both parts specify 100,000 electrical cycles and 10,000,000 mechanical cycles, indicating identical reliability expectations under specified operating conditions.

Q: What is the operating temperature range difference between these parts?

A: The Panasonic part operates from -25°C to 105°C, while the Crouzet part operates from -40°C to 85°C. Application temperature requirements should be evaluated against these ranges to confirm suitability.

Q: Is the Crouzet part currently available?

A: Yes. The Crouzet 831607B6.A carries active product status with 1,095 units in stock, ensuring availability for immediate procurement and future reorders.
