AM51622D73N-A Equivalent & Substitute Parts

Part Overview

The AM51622D73N-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 at 125V AC. This chassis-mount switch features a straight lever actuator with quick-connect 0.250" (6.3mm) termination and is designed for momentary on operation. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM51622D73N-A is determined by the following critical parameters:

• Circuit Configuration: SPST-NC (single-pole, single-throw, normally-closed)
• Switch Function: On-Mom (momentary operation)
• Current Rating: Minimum 16A AC
• Voltage Rating: Minimum 125V AC
• Actuator Type: Lever, straight configuration
• Mounting Type: Chassis mount
• Termination Style: Quick connect 0.250" (6.3mm)

The Crouzet 83261622 qualifies as a substitute part because it maintains the same circuit configuration (SPST-NC), switch function (On-Mom), current rating (16A AC), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.250"). While the voltage rating differs (250V AC versus 125V AC), the higher voltage rating of the substitute part is compatible with applications designed for 125V AC operation.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261622 is suitable as a substitute for the obsolete AM51622D73N-A based on the following factors:

• Functional Equivalence: Both switches maintain identical circuit configuration (SPST-NC), switch function (On-Mom), current rating (16A AC), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.250").

• Voltage Compatibility: The Crouzet part is rated for 250V AC, which exceeds the 125V AC requirement of the original part. This higher voltage rating is compatible with 125V AC applications.

• Product Status: The Crouzet 83261622 is active and currently in production, providing long-term availability compared to the obsolete Panasonic part.

• Compliance: The Crouzet 83261622 is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements.

• Temperature Range: The Crouzet part operates across -20°C to 125°C, which encompasses the original part's operating range of -25°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261622 directly replace the AM51622D73N-A in existing applications?

A: Yes, the Crouzet 83261622 is functionally equivalent for applications requiring SPST-NC momentary operation at 16A and 125V AC. The identical actuator type, mounting configuration, and termination style ensure mechanical and electrical compatibility.

Q: Why does the Crouzet part have a higher voltage rating (250V AC) than the original (125V AC)?

A: A higher voltage rating indicates the component can safely operate at voltages up to 250V AC. This does not affect operation at 125V AC and is compatible with the original application requirements.

Q: Are there any mechanical differences between these switches?

A: Both switches feature identical actuator types (lever, straight), mounting types (chassis mount), and termination styles (quick connect 0.250"). Operating position, pretravel, differential travel, and overtravel specifications differ slightly but do not affect functional substitution for standard applications.

Q: What is the significance of the Crouzet part being RoHS Compliant?

A: RoHS Compliance indicates the Crouzet 83261622 meets Restriction of Hazardous Substances regulations, making it suitable for applications and markets requiring compliance with environmental and safety standards.

Q: Is the Crouzet 83261622 available in the same packaging as the AM51622D73N-A?

A: Both parts use identical quick-connect 0.250" (6.3mm) termination and chassis-mount configuration, ensuring compatibility with existing mechanical installations and electrical connections.
