AM51652C63N-A Equivalent & Substitute Parts

Part Overview

The AM51652C63N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally closed (SPST-NC) device with a 16A AC rating at 125V. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The switch features a lever actuator with straight configuration and chassis mount termination via quick connect terminals.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51652C63N-A is determined by the following critical parameters:

Primary Matching Criteria:

• Circuit configuration: SPST-NC
• Switch function: On-Mom (momentary)
• Actuator type: Lever, straight
• Mounting type: Chassis mount
• Termination style: Quick Connect - 0.187" (4.7mm)

Electrical Compatibility Criteria:

• Current rating: Minimum 16A AC
• Voltage rating: Minimum 125V AC
• DC current capability: Minimum 600mA at 125V DC

Mechanical Compatibility Criteria:

• Operating position tolerance: Within ±0.050" of 0.602" (15.3mm)
• Pretravel and differential travel: Compatible with existing mechanical linkages
• Operating force: Within acceptable range for existing actuator design

The Crouzet 83261642 qualifies as a substitute based on matching circuit configuration, switch function, actuator geometry, mounting type, and termination style. The substitute part exceeds the minimum electrical requirements with a 250V AC rating and maintains mechanical compatibility within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261642 is a qualified substitute for the obsolete Panasonic AM51652C63N-A based on matching electrical circuit configuration, mechanical interface geometry, and termination compatibility. The substitute part maintains active product status, ensuring continued availability and supply chain stability.

Electrical Considerations: The Crouzet substitute provides a higher voltage rating (250V AC versus 125V AC), which is compatible with applications designed for the original 125V specification. No derating is required for voltage-limited applications.

Mechanical Considerations: Operating position variance of 0.004" (0.1mm) and operating force increase of 24gf fall within typical mechanical tolerance bands for lever-actuated switch applications. These variations do not preclude direct substitution in standard chassis-mounted installations.

Compliance and Certification: Both parts share identical ECCN (EAR99) and HTSUS classifications. The Crouzet substitute carries RoHS Compliance and REACH Unaffected certifications, meeting modern regulatory requirements.

Lifecycle Consideration: The original part specifies 10,000,000 mechanical cycles versus the substitute's 1,000,000 cycles. Applications requiring extended mechanical life should evaluate duty cycle requirements against the substitute's rated mechanical endurance.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261642 directly replace the Panasonic AM51652C63N-A in existing assemblies?

A: Yes, the Crouzet substitute is mechanically and electrically compatible for direct replacement. Identical mounting type, termination style, and circuit configuration ensure compatibility with existing mechanical linkages and electrical connections. The 0.004" variation in operating position is within standard mechanical tolerances.

Q: What is the significance of the operating force difference (180gf vs. 204gf)?

A: The 24gf increase in operating force for the Crouzet substitute represents approximately a 13% increase in actuation effort. This variation is typical between different manufacturers' snap-action switch designs and does not preclude substitution in standard applications. Applications with specific actuation force requirements should verify compatibility with the substitute's specification.

Q: Does the higher voltage rating (250V AC) of the Crouzet part affect compatibility?

A: No. The substitute's 250V AC rating exceeds the original 125V AC requirement, making it suitable for the original application without modification. Higher voltage ratings do not create compatibility issues in voltage-limited circuits.

Q: Why does the Crouzet substitute have lower mechanical life (1,000,000 vs. 10,000,000 cycles)?

A: Mechanical life ratings reflect design and manufacturing differences between manufacturers. For applications operating within normal duty cycles, the Crouzet substitute's 1,000,000-cycle rating is adequate for most industrial and commercial switch applications. Applications requiring extended mechanical endurance should evaluate actual duty cycle requirements.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts share identical ECCN and HTSUS classifications. The Crouzet substitute carries RoHS Compliance and REACH Unaffected certifications, meeting current regulatory standards. The original Panasonic part does not specify these certifications, making the Crouzet substitute preferable for applications requiring modern compliance documentation.

Q: What is the impact of the extended temperature range of the Crouzet part (-20°C to 125°C vs. -25°C to 105°C)?

A: The Crouzet substitute provides a higher upper temperature limit (125°C vs. 105°C) and a slightly higher lower temperature limit (-20°C vs. -25°C). For applications operating within the original -25°C to 105°C range, the substitute remains fully compatible. Applications requiring operation below -20°C should retain the original specification.
