AM50064A33-A Equivalent & Substitute Parts

Part Overview

The AM50064A33-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works. This chassis-mount switch is rated for 100mA at 125V AC and 30V DC, featuring a lever with simulated roller actuator and solder/quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for design continuity and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50064A33-A requires matching the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Switch Function: Off-Momentary operation
• Mounting Type: Chassis mount form factor
• Actuator Type: Lever-based actuation mechanism
• Termination Compatibility: Quick-connect or solder termination suitable for the application
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification (100mA, 125V AC minimum)
• Operating Temperature Range: Functional range must encompass the application environment
• Mechanical Reliability: Cycle life adequate for intended duty cycle

The Crouzet 83265822 qualifies as a substitute based on matching circuit topology, switch function, mounting type, lever actuator, and quick-connect termination. The substitute provides enhanced electrical ratings (5A at 250V AC) and extended temperature range (-20°C to 125°C), making it suitable for applications requiring the AM50064A33-A.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265822 is an active product with RoHS compliance and REACH unaffected status, providing regulatory advantages over the obsolete AM50064A33-A. The substitute delivers superior electrical ratings (5A at 250V AC versus 100mA at 125V AC), accommodating higher-power applications while maintaining backward compatibility with the original SPST-NO, off-momentary circuit topology.

Key considerations for selection:

• Actuator Geometry: The Crouzet features a straight lever versus the simulated roller of the original. Physical mounting space and actuation method must be evaluated for the specific application.
• Termination Connector Size: Quick-connect terminals differ (0.250" versus 0.187"), requiring PCB or harness redesign.
• Mechanical Life: The substitute provides 1,000,000 cycles versus 10,000,000 cycles in the original. Applications requiring extended cycle life must assess this reduction.
• Regulatory Compliance: Active product status and RoHS/REACH certifications support long-term supply chain stability and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265822 directly replace the AM50064A33-A without circuit modification?

A: The Crouzet 83265822 maintains the same SPST-NO circuit topology and off-momentary function, making it electrically compatible. However, the larger quick-connect terminal size (0.250" versus 0.187") requires harness or PCB connector redesign. Physical mounting geometry differences due to actuator type must also be evaluated.

Q: What are the key electrical differences between these parts?

A: The Crouzet substitute provides significantly higher current capacity (5A versus 100mA) and voltage rating (250V AC versus 125V AC). This allows the substitute to handle higher-power switching applications. The original part's 30V DC rating is not specified for the substitute, requiring confirmation if DC operation is required.

Q: Why is mechanical life lower in the substitute?

A: The Crouzet 83265822 specifies 1,000,000 mechanical cycles compared to 10,000,000 in the original AM50064A33-A. Applications with high-frequency actuation cycles must assess whether this reduction impacts product lifecycle requirements.

Q: Are there compliance or supply chain advantages to using the Crouzet part?

A: Yes. The Crouzet 83265822 is an active product with RoHS compliance and REACH unaffected status, ensuring ongoing availability and regulatory alignment. The AM50064A33-A is obsolete, creating long-term sourcing risk.

Q: What physical modifications are required for substitution?

A: Termination connector redesign is mandatory due to quick-connect terminal size differences. Mounting bracket or mechanical interface may require adjustment based on actuator geometry (straight lever versus simulated roller). Prototype testing is necessary to confirm fit and function in the specific application enclosure.
