AM50064D53-A Equivalent & Substitute Parts

Part Overview

The AM50064D53-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works, designed for chassis mount applications with a 0.1A rating at 125V AC. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing maintenance, repair, and new design implementations where legacy compatibility is required.

The switch features a lever-actuated simulated roller mechanism with quick connect termination, suitable for low-current control applications. Given its obsolete status, equivalent alternatives from active manufacturers are necessary to ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50064D53-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Momentary
• Actuator type must be Lever with Simulated Roller mechanism
• Mounting type must be Chassis Mount
• Termination must be Quick Connect style

Electrical Compatibility Criteria:

• Current rating must equal or exceed 100mA
• Voltage rating (AC) must equal or exceed 125V
• Voltage rating (DC) must equal or exceed 30V

Mechanical Compatibility Criteria:

• Operating temperature range must encompass or exceed -25°C to 105°C
• Mechanical life must support application duty cycle requirements

The substitute part Crouzet 83265846 meets all primary compatibility criteria and exceeds electrical specifications, making it a valid functional equivalent for the obsolete AM50064D53-A.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265846 is a functional equivalent for the obsolete AM50064D53-A based on the following engineering criteria:

Functional Compatibility: Both switches share identical circuit configuration (SPST-NO), switch function (Off-Momentary), actuator mechanism (Lever with Simulated Roller), and mounting type (Chassis Mount). These parameters define the core switching behavior required for replacement applications.

Electrical Superiority: The Crouzet substitute exceeds the original part's electrical specifications with 5A current capacity versus 100mA, and 250V AC rating versus 125V AC. This provides enhanced capability margin for the application.

Compliance Status: The Crouzet 83265846 is an active product with RoHS compliance certification, ensuring ongoing availability and regulatory alignment for new designs and repairs.

Termination Consideration: The substitute features a 0.187" (4.7mm) quick connect termination versus the original 0.250" (6.3mm). Connector compatibility must be evaluated for the specific application harness.

Mechanical Life Difference: The substitute provides 1,000,000 cycles of mechanical life compared to the original 10,000,000 cycles. Application duty cycle requirements must be assessed to confirm adequacy.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265846 directly replace the AM50064D53-A in existing applications?

A: Functional replacement is possible if the application meets these conditions: the circuit requires SPST-NO switching with Off-Momentary function, the connector harness accommodates the 0.187" (4.7mm) quick connect termination, and the duty cycle does not exceed 1,000,000 mechanical cycles. Electrical specifications of the Crouzet part exceed the original requirements.

Q: What is the primary difference between these two switches?

A: The AM50064D53-A is an obsolete Panasonic component with 100mA/125V AC rating, while the Crouzet 83265846 is an active product with 5A/250V AC rating. Both share identical switching architecture (SPST-NO, lever-actuated, chassis mount), but differ in current capacity, voltage rating, termination connector size, and mechanical life specification.

Q: Are there compatibility issues with the different quick connect termination sizes?

A: Yes. The AM50064D53-A uses 0.250" (6.3mm) quick connect terminals, while the Crouzet 83265846 uses 0.187" (4.7mm) terminals. The application harness connector must be compatible with the substitute part's termination style. Physical adapter solutions or harness modification may be required.

Q: Does the Crouzet part meet modern regulatory requirements?

A: Yes. The Crouzet 83265846 is RoHS compliant and carries active product status, ensuring compliance with current environmental and safety regulations. The original AM50064D53-A does not specify RoHS compliance.

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

A: The AM50064D53-A specifies 10,000,000 mechanical cycles, while the Crouzet substitute specifies 1,000,000 cycles. For applications with high-frequency actuation, the reduced mechanical life of the substitute must be evaluated against actual duty cycle requirements to ensure adequate service life.
