AM51150D43N-A Equivalent & Substitute Parts

Part Overview

The AM51150D43N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NC (Single Pole Single Throw - Normally Closed) chassis mount component. This switch is rated for 11A AC at 125V and features a round pin plunger actuator with quick connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51150D43N-A is determined by the following critical parameters:

• Circuit Configuration: SPST-NC topology must be maintained
• Switch Function: On-Mom (momentary) operation required
• Actuator Type: Round pin plunger design
• Mounting Type: Chassis mount configuration
• Termination Style: Quick connect 0.250" (6.3mm) terminals
• Operating Position: 0.579" (14.7mm) stroke length
• Electrical Ratings: AC current capacity minimum 11A; AC voltage minimum 125V

The Crouzet 83264621 qualifies as a functional substitute based on matching circuit configuration (SPST-NC), switch function (On-Mom), actuator type (round pin plunger), mounting type (chassis mount), termination style (quick connect 0.250"), and operating position (0.579"). The substitute provides enhanced electrical ratings (12A AC @ 250V) and improved operating temperature range (-20°C to 125°C), making it suitable for applications requiring the AM51150D43N-A.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264621 is an active product with RoHS compliance certification, providing continuity for applications currently using the obsolete AM51150D43N-A. The substitute maintains identical mechanical and electrical interface characteristics while offering superior voltage rating (250V vs. 125V) and extended upper operating temperature limit (125°C vs. 105°C). Selection of the Crouzet alternative eliminates obsolescence risk and ensures access to current manufacturing and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264621 directly replace the AM51150D43N-A in existing assemblies?

A: Yes. Both switches share identical circuit configuration (SPST-NC), switch function (On-Mom), actuator type (round pin plunger), mounting type (chassis mount), termination style (quick connect 0.250"), and operating position (0.579"). Physical and electrical interfaces are compatible.

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

A: The Crouzet 83264621 provides higher AC voltage rating (250V vs. 125V), increased current capacity (12A vs. 11A AC), extended upper operating temperature (125°C vs. 105°C), and RoHS compliance. The AM51150D43N-A supports DC operation at 600mA, which is not specified for the Crouzet substitute.

Q: Is the Crouzet 83264621 suitable for applications requiring DC operation?

A: DC ratings are not provided for the Crouzet 83264621. If DC operation at 600mA is required, alternative substitutes must be evaluated or the original specification must be reconsidered.

Q: What is the mechanical life difference between these switches?

A: The AM51150D43N-A is rated for 10,000,000 mechanical cycles, while the Crouzet 83264621 is rated for 1,000,000 cycles. Applications requiring extended mechanical life should account for this difference.

Q: Are there any compliance or certification advantages to using the Crouzet substitute?

A: The Crouzet 83264621 carries RoHS compliance and REACH unaffected status certifications. The AM51150D43N-A compliance certifications are not specified in available documentation.
