AM50056C53-A Equivalent & Substitute Parts

Part Overview

The AM50056C53-A is a SPST-NC (Single Pole Single Throw - Normally Closed) snap-action switch manufactured by Panasonic Electric Works. This chassis-mounted switch is designed for low-current applications with a rated capacity of 100mA at 125V AC and 30V DC. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support. The lever-roller actuator with quick-connect termination provides reliable mechanical switching for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50056C53-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NC to maintain identical electrical behavior
• Switch Function: Must be On-Momentary for functional compatibility
• Actuator Type: Must include Lever and Roller to ensure mechanical interchangeability
• Mounting Type: Must be Chassis Mount for physical installation compatibility
• Termination Style: Must be Quick Connect - 0.187" (4.7mm) for connector compatibility

The Crouzet 83265647 qualifies as a substitute because it matches all critical parameters. While the Crouzet part exceeds the current and voltage ratings of the original (5A at 250V AC versus 100mA at 125V AC), this represents a performance upgrade that maintains full backward compatibility. The identical circuit configuration, switch function, actuator type, mounting method, and termination style ensure direct functional substitution in the AM50056C53-A application.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265647 is the qualified substitute for the obsolete AM50056C53-A. Selection is based on the following engineering criteria:

Functional Compatibility: Both switches share identical circuit configuration (SPST-NC), switch function (On-Momentary), actuator type (Lever, Roller), mounting method (Chassis Mount), and termination style (Quick Connect - 0.187"). These parameters ensure direct functional substitution without circuit redesign.

Performance Upgrade: The Crouzet part provides higher current capacity (5A versus 100mA) and higher AC voltage rating (250V versus 125V). This represents a performance upgrade that maintains full backward compatibility with the original application.

Product Status: The Crouzet 83265647 is currently active in production, ensuring long-term availability and supply chain continuity compared to the obsolete Panasonic part.

Compliance: The Crouzet part carries RoHS Compliance certification, meeting modern environmental and regulatory standards.

Mechanical Characteristics: Operating position values are nearly identical (0.806" versus 0.815"), confirming mechanical interchangeability. The Crouzet part features lower operating force (25gf versus 120gf), which may reduce actuator effort in applications where this is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265647 directly replace the AM50056C53-A without circuit modifications?

A: Yes. Both switches share identical circuit configuration (SPST-NC), switch function (On-Momentary), actuator type (Lever, Roller), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). Direct substitution is possible without circuit redesign.

Q: Why does the Crouzet part have higher current and voltage ratings?

A: The Crouzet 83265647 is rated for 5A at 250V AC, compared to the AM50056C53-A at 100mA at 125V AC. This represents a performance upgrade. The substitute can safely handle the original application's electrical requirements while providing additional capacity margin.

Q: Are the mechanical dimensions compatible?

A: Yes. Operating position values are nearly identical: 0.806" (Crouzet) versus 0.815" (Panasonic). Both switches use the same Quick Connect - 0.187" (4.7mm) termination, ensuring mechanical and electrical interchangeability in the chassis mount installation.

Q: What is the difference in operating force between these switches?

A: The AM50056C53-A requires 120gf operating force, while the Crouzet 83265647 requires 25gf. The lower operating force of the substitute may reduce actuator effort, which can be advantageous in applications where ease of actuation is desired.

Q: Does the Crouzet part meet modern compliance standards?

A: Yes. The Crouzet 83265647 is RoHS Compliant and carries REACH Unaffected status, meeting current environmental and regulatory requirements. The original Panasonic part's compliance status is not specified.

Q: What is the mechanical life difference?

A: The AM50056C53-A is rated for 10,000,000 cycles, while the Crouzet 83265647 is rated for 1,000,000 cycles. For applications requiring extended mechanical life, this difference should be evaluated against actual duty cycle requirements.

Q: Is the Crouzet part currently available?

A: Yes. The Crouzet 83265647 is in active production status with 1,098 pieces in stock, ensuring reliable supply chain availability compared to the obsolete Panasonic part.
