AM51631C73N-A Equivalent & Substitute Parts

Part Overview

The AM51631C73N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device rated for 16A at 125V AC and 600mA at 125V DC. This component features a lever actuator with straight configuration and chassis mount termination using quick connect 0.187" (4.7mm) terminals. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications where continued sourcing of the original part is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51631C73N-A is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary action)
• Actuator type: Lever, straight
• Mounting type: Chassis mount
• Termination style: Quick Connect - 0.187" (4.7mm)

Electrical Compatibility Criteria:

• Current rating must meet or exceed 16A AC
• Voltage rating must meet or exceed 125V AC
• DC voltage rating must meet or exceed 125V DC

Mechanical Compatibility Criteria:

• Operating position tolerance within ±0.05" (1.3mm) of 0.602" (15.3mm)
• Pretravel and differential travel within acceptable mechanical envelope
• Operating temperature range must encompass or extend the -25°C to 105°C specification

The Crouzet 83261842 qualifies as a substitute based on matching circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.187"). The substitute exceeds electrical requirements with 250V AC rating and maintains mechanical compatibility through comparable operating position (0.606" vs. 0.602") and operating temperature range (-20°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261842 is an active product with RoHS compliance certification, providing a viable substitute for the obsolete AM51631C73N-A in applications requiring SPST-NO momentary switch functionality with lever actuation and quick connect termination.

The substitute part exceeds the original electrical specifications with a 250V AC rating compared to the 125V AC requirement, ensuring compatibility in circuits operating at or below the original voltage specification. Both parts maintain identical current handling capacity at 16A AC and share mechanical interface characteristics through matching actuator type, mounting configuration, and termination style.

The operating temperature range of the Crouzet part (-20°C to 125°C) extends the upper limit beyond the original specification (-25°C to 105°C), providing enhanced thermal performance. Operating position measurements differ by 0.004" (0.1mm), which falls within acceptable mechanical tolerance for chassis-mounted switch applications.

The mechanical life rating of the Crouzet part (1,000,000 cycles) is lower than the original (10,000,000 cycles). This difference must be evaluated against the specific duty cycle requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261842 directly replace the AM51631C73N-A in existing assemblies?

A: Yes, provided the application operates at or below 125V AC and 16A AC. The matching circuit configuration (SPST-NO), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.187") ensure mechanical and electrical compatibility. The higher voltage rating of the Crouzet part does not create compatibility issues in lower-voltage applications.

Q: What is the significance of the mechanical life difference between these parts?

A: The AM51631C73N-A is rated for 10,000,000 mechanical cycles, while the Crouzet 83261842 is rated for 1,000,000 cycles. Applications requiring frequent actuation over extended service intervals should evaluate whether the lower cycle rating of the substitute meets operational requirements.

Q: Are there compliance differences between the original and substitute parts?

A: The Crouzet 83261842 carries RoHS compliance certification and REACH unaffected status. The original part's compliance certifications are not specified in available documentation. Both parts share the same ECCN (EAR99) and HTSUS classification (8536.50.9040).

Q: How do the operating force and release force specifications compare?

A: The AM51631C73N-A specifies 420gf operating force and 80gf release force. The Crouzet 83261842 specifies 204gf operating force and 51gf release force. These differences may affect tactile feedback and actuation characteristics in user-operated applications.

Q: What is the impact of the operating temperature range difference?

A: The Crouzet part operates from -20°C to 125°C compared to the original -25°C to 105°C. The substitute provides a 20°C higher upper temperature limit but a 5°C higher lower temperature limit. Applications operating below -20°C require verification of the original part's continued availability or identification of alternative solutions.
