AM51654C63N-A Equivalent & Substitute Parts

Part Overview

The AM51654C63N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device with a 16A AC rating at 125V. This component is designed for chassis-mount applications with quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51654C63N-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NC
• Switch function: On-Mom (momentary)
• Mounting type: Chassis mount
• Termination style: Quick Connect - 0.187" (4.7mm)
• Actuator type: Lever with simulated roller

Electrical Compatibility Criteria:

• Current rating: Minimum 16A AC
• Voltage rating: Minimum 125V AC
• DC ratings: Minimum 600mA at 125V DC

Mechanical Compatibility Criteria:

• Operating temperature range must encompass or exceed -25°C to 105°C
• Mechanical life rating: Minimum 10,000,000 cycles

The Crouzet 83261646 meets all primary compatibility criteria and exceeds electrical specifications with a 250V AC rating. Mechanical life is lower at 1,000,000 cycles, which represents a reduction from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261646 is functionally equivalent to the AM51654C63N-A for applications requiring SPST-NC momentary switching at 16A AC. The substitute part exceeds the original voltage specification (250V vs. 125V), providing additional electrical margin in AC applications.

The Crouzet part is currently in active production status, ensuring availability for replacement and repair applications. The component is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

The primary consideration is the reduced mechanical life rating of the Crouzet part (1,000,000 cycles versus 10,000,000 cycles). Applications requiring extended cycle life or high-frequency switching should evaluate this specification against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261646 directly replace the Panasonic AM51654C63N-A?

A: Yes, for applications operating at or below 125V AC and 16A. The Crouzet part maintains identical circuit configuration, switch function, mounting type, and termination style. The higher voltage rating of the Crouzet part does not affect compatibility in lower-voltage applications.

Q: What is the significance of the reduced mechanical life rating in the Crouzet substitute?

A: The Crouzet part is rated for 1,000,000 mechanical cycles compared to 10,000,000 cycles for the original Panasonic part. This specification should be evaluated against the actual switching frequency and expected service life of the application. Applications with infrequent switching may not be affected by this difference.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use identical quick-connect termination (0.187" / 4.7mm) and chassis-mount configuration. Operating position differs slightly (0.730" for Panasonic versus 0.803" for Crouzet), which may affect mechanical integration in space-constrained designs.

Q: What compliance certifications apply to the substitute part?

A: The Crouzet 83261646 is RoHS Compliant and REACH Unaffected. Both parts carry EAR99 export classification and fall under HTSUS code 8536.50.9040.

Q: Is the Crouzet part suitable for DC applications?

A: The provided specifications for the Crouzet part do not include DC current or voltage ratings. The original Panasonic part is rated for 600mA DC at 125V. DC compatibility of the Crouzet substitute should be verified through the manufacturer before application in DC circuits.
