AM51663D53N-A Equivalent & Substitute Parts

Part Overview

The AM51663D53N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with chassis mount installation. This switch is rated for 16A AC at 125V and features a straight lever actuator with quick connect termination. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51663D53N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Current rating must support minimum 16A AC
• Voltage rating must support minimum 125V AC
• Actuator type must be lever with straight configuration
• Mounting type must be chassis mount
• Termination style must be quick connect 0.250" (6.3mm)

The Crouzet 83261824 meets these substitution criteria. It maintains identical circuit topology, switch function, current rating, actuator geometry, mounting configuration, and termination interface. The substitute part exceeds the voltage specification (250V AC vs. 125V AC), which is acceptable for direct substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261824 is a direct functional substitute for the obsolete AM51663D53N-A. Both switches share identical electrical circuit topology, current handling capacity, actuator configuration, and mechanical interface specifications. The Crouzet part is currently in active production status, ensuring long-term availability and supply chain continuity.

The Crouzet substitute provides enhanced voltage rating (250V AC) compared to the original specification (125V AC), which presents no compatibility issues for applications designed around the original part. The operating temperature range of the Crouzet part (-20°C to 125°C) covers the original operating range with extended upper temperature capability.

The Crouzet 83261824 carries RoHS compliance certification and REACH unaffected status, meeting modern regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261824 directly replace the AM51663D53N-A in existing applications?

A: Yes. Both switches share identical SPST-NO circuit configuration, 16A AC current rating, straight lever actuator, chassis mount installation, and 0.250" quick connect termination. The Crouzet part's higher voltage rating (250V AC) does not prevent substitution in 125V AC applications.

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

A: The primary differences are manufacturer origin, product status (obsolete vs. active), and mechanical life rating. The Crouzet part specifies 1,000,000 mechanical cycles versus 10,000,000 for the original. Operating force and release force values differ slightly (61gf vs. 60gf operating force; 15gf vs. 10gf release force). The Crouzet part operates across a wider temperature range (-20°C to 125°C vs. -25°C to 105°C).

Q: Are there packaging or certification differences?

A: The Crouzet 83261824 is RoHS compliant and REACH unaffected. The original AM51663D53N-A specifies Cadmium Free construction. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control status.

Q: What termination interface do these switches use?

A: Both switches use Quick Connect - 0.250" (6.3mm) termination, ensuring mechanical and electrical compatibility in existing connector and wiring configurations.
