AM50066A33-A Equivalent & Substitute Parts

Part Overview

The AM50066A33-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 roller actuator with solder and quick-connect termination options. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50066A33-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical behavior
• Switch Function: Must be Off-Momentary for functional compatibility
• Actuator Type: Lever roller actuator required for mechanical interface compatibility
• Mounting Type: Chassis mount required for installation compatibility
• Current and Voltage Ratings: Substitute must meet or exceed the 100mA AC/DC and 125V AC / 30V DC ratings to ensure safe operation in the original application
• Operating Temperature Range: Must accommodate the -25°C to 105°C operating environment
• Termination Style: Quick-connect or solder termination acceptable for electrical connection compatibility

The Crouzet 83265827 qualifies as a functional substitute based on matching circuit configuration (SPST-NO), switch function (Off-Momentary), actuator type (Lever, Roller), and mounting type (Chassis Mount). The substitute exceeds the current and voltage ratings of the original part, providing enhanced electrical capacity for the application.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265827 is an active product with current manufacturing support, making it suitable for applications requiring component replacement or redesign of systems using the obsolete AM50066A33-A. The substitute part exceeds the electrical ratings of the original component, providing operational margin in current capacity (5A versus 100mA) and AC voltage rating (250V versus 125V).

Mechanical life specification differs between the two parts: the original AM50066A33-A specifies 10,000,000 cycles while the Crouzet substitute specifies 1,000,000 cycles. Applications requiring extended mechanical cycling should evaluate this parameter against actual duty cycle requirements.

The Crouzet 83265827 is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The quick-connect termination style differs in pin size (0.250" versus 0.187"), requiring connector compatibility verification during integration.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265827 directly replace the AM50066A33-A without modification?

A: Functional substitution is possible based on matching circuit configuration, switch function, and actuator type. However, the quick-connect termination pin size differs (0.250" versus 0.187"), requiring connector compatibility assessment. Solder termination is not available on the Crouzet part.

Q: What are the key differences in electrical ratings?

A: The Crouzet substitute exceeds the original part in current capacity (5A versus 100mA AC) and AC voltage rating (250V versus 125V). DC voltage rating is not specified for the Crouzet part; applications requiring DC operation should confirm compatibility with the manufacturer.

Q: How do mechanical life specifications compare?

A: The AM50066A33-A specifies 10,000,000 mechanical cycles, while the Crouzet 83265827 specifies 1,000,000 cycles. Applications with high-cycle duty should evaluate whether the reduced mechanical life rating is acceptable for the intended use.

Q: Are there compliance or regulatory differences?

A: The Crouzet 83265827 is RoHS Compliant and REACH Unaffected. The AM50066A33-A specifications do not include these compliance certifications. Both parts carry EAR99 ECCN classification and 8536.50.7000 HTSUS code.

Q: What is the operating temperature compatibility?

A: The AM50066A33-A operates from -25°C to 105°C. The Crouzet substitute operates from -20°C to 125°C, providing a wider upper temperature range but a slightly narrower lower temperature range. Applications operating below -20°C should confirm suitability with the manufacturer.
