AM50064A43-A Equivalent & Substitute Parts

Part Overview

The AM50064A43-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 AM50064A43-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
• Electrical Ratings: Current and voltage capacity must meet or exceed the original specification
• Termination Compatibility: Quick-connect or solder termination suitable for the application
• Environmental Compliance: MSL rating and operating temperature range

The Crouzet 83265822 qualifies as a functional equivalent based on matching circuit configuration (SPST-NO), switch function (Off-Momentary), mounting type (Chassis Mount), actuator type (Lever), and termination style (Quick Connect). The substitute part exceeds the electrical ratings of the original component, providing enhanced current capacity (5A vs. 100mA) and voltage rating (250V AC vs. 125V AC).

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265822 is an active product with current manufacturing support, addressing the obsolescence status of the AM50064A43-A. Both components share identical circuit topology (SPST-NO) and switch function (Off-Momentary), ensuring functional compatibility in applications requiring momentary contact switching.

The Crouzet substitute provides superior electrical performance with 5A current capacity versus the original 100mA rating, and 250V AC rating versus 125V AC. The operating temperature range of -20°C to 125°C encompasses the original -25°C to 105°C specification. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification.

Termination style differs between components: the original features 0.187" (4.7mm) quick-connect terminals with solder option, while the substitute uses 0.250" (6.3mm) quick-connect terminals. PCB layout and connector compatibility must be evaluated during integration.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265822 directly replace the AM50064A43-A in existing designs?

A: Functional replacement is possible due to matching SPST-NO circuit configuration and Off-Momentary switch function. However, termination connector size differs (0.250" vs. 0.187"), requiring PCB or harness modification. Mechanical envelope and actuator geometry should be verified against the original design constraints.

Q: What are the key differences in electrical performance?

A: The Crouzet substitute exceeds the original specifications: 5A current capacity versus 100mA, and 250V AC rating versus 125V AC. These higher ratings provide design margin and are suitable for applications originally specified for the lower-rated Panasonic component.

Q: Are both components RoHS and REACH compliant?

A: The Crouzet 83265822 is RoHS Compliant and REACH Unaffected. Compliance documentation for the obsolete Panasonic AM50064A43-A is not provided in the available data.

Q: What is the mechanical life difference between these components?

A: The original Panasonic component specifies 10,000,000 mechanical cycles, while the Crouzet substitute specifies 1,000,000 mechanical cycles. Applications requiring extended mechanical life cycling should account for this difference.

Q: How do the actuator types differ?

A: The AM50064A43-A features a lever with simulated roller actuator, while the Crouzet 83265822 uses a straight lever actuator. Actuation force and feel may differ; operating force is 60gf for the original versus 25gf for the substitute.
