AM50056C33-A Equivalent & Substitute Parts

Part Overview

The AM50056C33-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 100mA rating at 125V AC and 30V DC. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support. The switch features a lever-roller actuator with quick-connect termination and is rated for 100,000 electrical cycles and 10,000,000 mechanical cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50056C33-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NC
• Switch function must be On-Momentary
• Actuator type must include Lever and Roller options
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)

Electrical Performance 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 Criteria:

• Operating position tolerance must be compatible (±0.815")
• Pretravel, differential travel, and overtravel must be within acceptable mechanical envelope

The Crouzet 83265647 qualifies as a substitute based on matching circuit configuration (SPST-NC), switch function (On-Momentary), actuator type (Lever, Roller), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). The Crouzet part exceeds the electrical requirements with 5A AC current rating and 250V AC voltage rating, providing enhanced electrical capacity for the same mechanical interface.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265647 is a qualified substitute for the obsolete AM50056C33-A based on functional and electrical compatibility. Key selection factors:

Electrical Capacity: The Crouzet part provides 5A AC current rating versus the original 100mA requirement, and 250V AC versus 125V AC requirement. This enhanced capacity ensures the substitute can handle the original application load with margin.

Mechanical Interface: Both parts share identical termination style (Quick Connect - 0.187"), mounting type (Chassis Mount), and actuator configuration (Lever, Roller). Operating position values are within 0.009" (0.2mm) of each other, confirming mechanical compatibility in the chassis mount envelope.

Product Status: The Crouzet part is actively manufactured and in stock (1,098 units available), whereas the Panasonic original is obsolete. Active manufacturing status ensures long-term availability for future replacements.

Compliance: The Crouzet part carries RoHS Compliant and REACH Unaffected certifications, meeting modern regulatory requirements. Both parts share the same ECCN (EAR99) and HTSUS classification.

Operational Considerations: The Crouzet part operates at a lower actuator force (25gf versus 30gf), which may reduce operator fatigue in high-cycle applications. The Crouzet part supports a wider operating temperature range (-20°C to 125°C versus -25°C to 105°C), providing additional thermal margin in extreme environments.

Mechanical Life Trade-off: The original Panasonic part is rated for 10,000,000 mechanical cycles, while the Crouzet substitute is rated for 1,000,000 cycles. For applications requiring the highest cycle count, this difference should be evaluated against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265647 directly replace the AM50056C33-A in existing equipment?

A: Yes, the Crouzet part is mechanically and electrically compatible. Both switches share the same SPST-NC circuit configuration, On-Momentary function, Lever-Roller actuator, Chassis Mount configuration, and Quick Connect - 0.187" termination. No wiring or mechanical modifications are required for substitution.

Q: What are the key differences between these two switches?

A: The primary differences are: (1) Current rating: Crouzet provides 5A AC versus Panasonic's 100mA, (2) Voltage rating: Crouzet rated for 250V AC versus Panasonic's 125V AC, (3) Operating force: Crouzet requires 25gf versus Panasonic's 30gf, (4) Mechanical life: Panasonic rated for 10,000,000 cycles versus Crouzet's 1,000,000 cycles, (5) Product status: Crouzet is active production while Panasonic is obsolete.

Q: Is the Crouzet part suitable for high-cycle applications?

A: The Crouzet part is rated for 1,000,000 mechanical cycles, which is lower than the original Panasonic rating of 10,000,000 cycles. For applications requiring sustained high-cycle operation, verify that the actual duty cycle does not exceed the Crouzet specification. For lower-cycle applications, the Crouzet part is fully suitable.

Q: Are there any compliance or certification differences?

A: The Crouzet part carries RoHS Compliant and REACH Unaffected certifications, meeting current regulatory standards. Both parts share the same ECCN (EAR99) and HTSUS (8536.50.7000) classifications. The Crouzet part meets modern environmental and trade compliance requirements.

Q: What is the operating force difference, and does it matter?

A: The Crouzet part requires 25gf operating force versus the Panasonic's 30gf. This 5gf reduction may be beneficial in applications where operator fatigue is a concern or where consistent actuation force is critical. The difference is within typical manufacturing tolerances for snap-action switches.

Q: Can I use the Crouzet part in applications requiring the full -25°C to 105°C temperature range?

A: The Crouzet part operates from -20°C to 125°C, which covers the original -25°C to 105°C range except for the lower extreme of -25°C. For applications requiring operation below -20°C, the original Panasonic specification must be maintained or an alternative substitute identified.
