AM51622D53N-A Equivalent & Substitute Parts

Part Overview

The AM51622D53N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device rated for 16A AC 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 AM51622D53N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NC
• Switch function must be On-Mom (momentary)
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.250" (6.3mm)
• Current and voltage ratings must meet or exceed the application requirements
• Actuator type must be Lever, Straight

The Crouzet 83262623 satisfies all mandatory substitution criteria. While it operates at higher voltage (250V AC) and current (20A AC) ratings, these represent enhanced electrical capability suitable for the AM51622D53N-A application envelope. The mechanical and operational characteristics remain compatible within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83262623 is a direct functional substitute for the AM51622D53N-A. The substitute part maintains identical circuit topology (SPST-NC), switch function (On-Mom), actuator geometry (Lever, Straight), mounting configuration (Chassis Mount), and termination interface (Quick Connect - 0.250").

The Crouzet part carries active product status, ensuring ongoing availability and supply chain continuity. The higher voltage and current ratings (250V AC, 20A AC versus 125V AC, 16A AC) provide enhanced electrical margin for the application. Operating temperature range extends to 125°C, exceeding the original specification. RoHS compliance and REACH unaffected status confirm regulatory alignment with current manufacturing standards.

Mechanical life specification differs (1,000,000 cycles versus 10,000,000 cycles); application duty cycle must be evaluated against this parameter if cycle count is a critical design constraint.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83262623 directly replace the AM51622D53N-A in existing assemblies?

A: Yes. Both parts share identical circuit configuration (SPST-NC), switch function (On-Mom), actuator type (Lever, Straight), mounting type (Chassis Mount), and termination style (Quick Connect - 0.250"). Physical dimensions and operational characteristics are compatible.

Q: What are the key differences between these parts?

A: The Crouzet part operates at higher electrical ratings (250V AC, 20A AC versus 125V AC, 16A AC) and supports a wider temperature range (-20°C to 125°C versus -25°C to 105°C). Mechanical life is specified at 1,000,000 cycles compared to 10,000,000 cycles for the original part. Operating force is lower (102gf versus 120gf).

Q: Is the higher voltage and current rating of the Crouzet part a concern?

A: No. Higher ratings indicate enhanced electrical capability and represent a conservative design margin for applications originally specified for the AM51622D53N-A.

Q: What is the impact of the lower mechanical life specification?

A: The Crouzet part is rated for 1,000,000 mechanical cycles versus 10,000,000 for the original. Applications requiring cycle counts exceeding 1,000,000 must evaluate this specification against actual duty cycle requirements.

Q: Are there compliance or certification differences?

A: The Crouzet 83262623 is RoHS Compliant and REACH Unaffected, confirming alignment with current environmental and regulatory standards. Both parts carry ECCN EAR99 and HTSUS 8536.50.9040 classifications.
