AM51624C63N-A Equivalent & Substitute Parts

Part Overview

The AM51624C63N-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 essential for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51624C63N-A is determined by the following critical parameters:

• Circuit configuration must remain SPST-NC
• Switch function must be On-Mom (momentary)
• Actuator type must be lever with simulated roller
• Mounting type must be chassis mount
• Termination style must be quick connect 0.187" (4.7mm)
• Current rating must support minimum 16A AC
• Voltage rating must support minimum 125V AC
• Operating temperature range must encompass the application environment

The Crouzet 83261646 satisfies these substitution criteria. While it operates at a higher voltage rating (250V AC) and exhibits different mechanical characteristics, it maintains functional equivalence for applications requiring SPST-NC momentary switching with identical mounting and termination specifications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261646 is an active product with RoHS compliance and REACH unaffected status, providing supply continuity advantages over the obsolete AM51624C63N-A. Both components share identical circuit configuration, switch function, current rating, actuator type, mounting method, and termination style. The Crouzet part operates at 250V AC, which exceeds the 125V AC requirement of the original specification and is therefore suitable for direct substitution in applications operating at or below 125V AC. The Crouzet component supports an extended upper operating temperature limit of 125°C compared to 105°C for the Panasonic part, providing additional thermal margin in high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261646 directly replace the AM51624C63N-A in existing designs?

A: Yes, for applications operating at 125V AC or lower. Both components share identical circuit configuration (SPST-NC), switch function (On-Mom), current rating (16A AC), actuator type (lever with simulated roller), mounting type (chassis mount), and termination style (quick connect 0.187"). The higher voltage rating of the Crouzet part does not prevent substitution in lower-voltage applications.

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

A: The components differ in operating force (180gf vs. 108gf), release force (30gf vs. 27gf), operating position (0.730" vs. 0.803"), differential travel (0.040" vs. 0.031"), and overtravel (0.055" vs. 0.070"). These differences may affect actuation feel and mechanical response characteristics but do not prevent functional substitution when circuit requirements are met.

Q: Are there any compliance or supply advantages to using the Crouzet part?

A: The Crouzet 83261646 is an active product with RoHS compliance and REACH unaffected status, whereas the Panasonic AM51624C63N-A is obsolete. Active product status ensures continued availability and supply chain reliability.

Q: Does the extended operating temperature range of the Crouzet part affect substitution suitability?

A: No. The Crouzet part's operating range of -20°C to 125°C encompasses the original part's range of -25°C to 105°C. The extended upper limit provides additional thermal margin but does not create incompatibility for applications within the original temperature specification.

Q: Are the quick-connect terminations physically identical?

A: Yes. Both components use quick-connect 0.187" (4.7mm) termination style, ensuring mechanical compatibility with existing connector interfaces and wiring harnesses.
