AM51652C73N-A Equivalent & Substitute Parts

Part Overview

The AM51652C73N-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 termination and is designed for momentary on operation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and system continuity in applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51652C73N-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NC
• Switch function must be On-Mom (momentary operation)
• Actuator type must be Lever, Straight
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)

Electrical Compatibility Criteria:

• Current rating must support minimum 16A AC
• Voltage rating must support minimum 125V AC
• Operating temperature range must encompass or exceed -25°C to 105°C

Mechanical Compatibility Criteria:

• Mechanical life must support application duty cycle requirements

The Crouzet 83261642 satisfies all primary compatibility criteria and exceeds electrical specifications with 16A AC at 250V AC rating, providing enhanced voltage margin. Operating temperature range extends to 125°C, exceeding the original specification. Mechanical life of 1,000,000 cycles is lower than the original part but remains suitable for standard industrial applications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261642 is a direct functional substitute for the AM51652C73N-A. Both switches share identical circuit configuration, switch function, actuator geometry, mounting method, and termination interface. The Crouzet part provides superior electrical specifications with 250V AC rating versus 125V AC, offering increased voltage margin for the same 16A current capacity.

The Crouzet 83261642 holds active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment with modern manufacturing standards. The original Panasonic part is obsolete, making the Crouzet substitute the appropriate choice for new procurement and system continuity.

The mechanical life specification of 1,000,000 cycles for the Crouzet part is lower than the original 10,000,000 cycles. This difference should be evaluated against actual application duty cycle requirements. For standard industrial control applications with typical momentary switch usage patterns, the Crouzet mechanical life rating is generally adequate.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261642 directly replace the AM51652C73N-A in existing applications?

A: Yes. Both switches share identical circuit configuration (SPST-NC), switch function (On-Mom), actuator type (Lever, Straight), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). Electrical specifications are compatible, with the Crouzet part rated for higher voltage (250V AC versus 125V AC).

Q: What is the primary reason for substitution?

A: The AM51652C73N-A is obsolete. The Crouzet 83261642 is an active product with equivalent functionality and superior electrical ratings, ensuring availability for replacement and new applications.

Q: Are there any mechanical differences between these switches?

A: The mechanical life rating differs: AM51652C73N-A is rated for 10,000,000 cycles, while the Crouzet 83261642 is rated for 1,000,000 cycles. Operating force and release force specifications also differ slightly. For standard industrial momentary switch applications, the Crouzet mechanical rating is suitable.

Q: Will the Crouzet part fit the same mounting location?

A: Yes. Both switches are chassis-mount devices with identical termination style (Quick Connect - 0.187" / 4.7mm), ensuring mechanical and electrical compatibility with existing panel cutouts and connector interfaces.

Q: What compliance certifications apply to the substitute part?

A: The Crouzet 83261642 is RoHS Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in industrial applications.
