AM50063D43-A Equivalent & Substitute Parts

Part Overview

The AM50063D43-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 straight lever actuator with quick-connect termination. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50063D43-A requires matching the following critical parameters:

Circuit Configuration: SPST-NO topology is mandatory for functional equivalence.

Switch Function: Off-Momentary operation must be preserved.

Mounting Type: Chassis mount configuration is required for mechanical compatibility.

Actuator Type: Straight lever actuator ensures consistent user interface and installation geometry.

Termination Style: Quick-connect termination must accommodate the existing connector interface.

Electrical Ratings: The substitute must meet or exceed the voltage and current requirements of the original circuit (125V AC minimum, 30V DC minimum, 100mA minimum current capacity).

Operating Temperature Range: The substitute must function within the specified thermal envelope or provide an extended range compatible with the application.

The Crouzet 83265842 qualifies as a substitute based on these criteria, with enhanced electrical ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265842 is suitable as a substitute for the obsolete AM50063D43-A based on the following factors:

Functional Equivalence: Both switches share identical circuit configuration (SPST-NO), switch function (Off-Momentary), actuator type (straight lever), and mounting type (chassis mount).

Electrical Capability: The Crouzet part exceeds the original specifications with 5A AC capacity versus 100mA, and 250V AC rating versus 125V AC. This provides margin for circuit protection and reliability.

Active Product Status: The Crouzet 83265842 is an active product with current manufacturing support, ensuring long-term availability and supply chain stability.

Compliance Certifications: The Crouzet part is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements.

Mechanical Compatibility: Operating position (0.606" vs. 0.602") and release force (5.099gf) are functionally equivalent. Operating force is slightly lower (25gf vs. 30gf), which may reduce actuation effort.

Termination Consideration: The quick-connect termination differs in size (0.187" vs. 0.250"). Connector compatibility must be verified during integration.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265842 directly replace the AM50063D43-A without modification?

A: Functional substitution is possible if the circuit requirements are met. However, the termination connector size differs (0.187" vs. 0.250"), requiring adapter verification or connector modification.

Q: What are the key differences in electrical ratings?

A: The Crouzet part provides higher current capacity (5A vs. 100mA) and higher AC voltage rating (250V vs. 125V). DC voltage rating is not specified for the Crouzet part. Both meet or exceed the original 100mA, 125V AC requirement.

Q: Does the lower operating force of the Crouzet switch affect functionality?

A: The Crouzet switch requires 25gf versus 30gf for the original. This 5gf reduction may result in slightly easier actuation but does not affect functional compatibility if the application tolerates this change.

Q: Are there compliance differences between the two parts?

A: The Crouzet 83265842 is RoHS Compliant and REACH Unaffected. The AM50063D43-A compliance status is not specified. For applications requiring modern regulatory compliance, the Crouzet part is preferable.

Q: What is the mechanical life difference, and does it matter?

A: The AM50063D43-A specifies 10,000,000 mechanical cycles versus 1,000,000 for the Crouzet part. For high-cycle applications, the original specification provides tenfold greater durability. Application cycle requirements must be evaluated.

Q: How do operating temperatures compare?

A: The AM50063D43-A operates from -25°C to 105°C. The Crouzet part operates from -20°C to 125°C. The Crouzet provides a higher upper temperature limit (+20°C advantage) but a slightly narrower lower limit (+5°C). For most applications, the Crouzet range is adequate.
