AM51150C43N-A Equivalent & Substitute Parts

Part Overview

The AM51150C43N-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 with a round pin plunger actuator. This part is rated for 11A AC at 125V and 600mA DC at 125V, with quick connect 0.187" (4.7mm) termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51150C43N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NC
• Switch function must be On-Mom (momentary operation)
• Actuator type must be round pin plunger
• Mounting type must be chassis mount
• Termination style must be quick connect 0.187" (4.7mm)
• Current and voltage ratings must meet or exceed the original specification
• Operating temperature range must encompass the application environment

The Crouzet 83264641 satisfies these substitution criteria. It maintains identical circuit configuration, switch function, actuator geometry, mounting method, and termination style. The Crouzet part provides higher current capacity (12A AC) and voltage rating (250V AC), with compatible operating position (0.579" / 14.7mm) and differential travel (0.016" / 0.4mm).

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264641 is a direct functional substitute for the obsolete AM51150C43N-A. Both components share identical circuit topology, actuator design, mounting configuration, and termination interface. The Crouzet part provides enhanced electrical performance with higher current capacity and voltage rating, making it suitable for applications requiring the original AM51150C43N-A specifications.

The Crouzet 83264641 holds active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs and production environments. The operating temperature range of -20°C ~ 125°C encompasses the original -25°C ~ 105°C specification, with the upper limit providing additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264641 directly replace the AM51150C43N-A in existing applications?

A: Yes. Both components are SPST-NC momentary switches with identical round pin plunger actuators, chassis mount configuration, and 0.187" (4.7mm) quick connect termination. The Crouzet part meets or exceeds all electrical and mechanical parameters of the original.

Q: What are the key compatibility factors for this substitution?

A: Circuit configuration (SPST-NC), switch function (On-Mom), actuator type (round pin plunger), mounting method (chassis mount), and termination style (quick connect 0.187") must remain unchanged. Current and voltage ratings must support the application load.

Q: Does the Crouzet part fit the same mechanical envelope?

A: Yes. The operating position of 0.579" (14.7mm) and differential travel of 0.016" (0.4mm) are identical between both components, ensuring compatible panel cutouts and mechanical interfaces.

Q: What is the significance of the product status difference?

A: The AM51150C43N-A is obsolete, meaning Panasonic Electric Works no longer manufactures or supports this component. The Crouzet 83264641 is active production, providing assured long-term availability and supply chain stability.

Q: Are there compliance or certification differences?

A: The Crouzet 83264641 is RoHS compliant and REACH unaffected. The original AM51150C43N-A specifications do not include these certifications. For applications requiring regulatory compliance, the Crouzet part provides documented certification.
