AM51622C73N-A Equivalent & Substitute Parts

Part Overview

The AM51622C73N-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 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 ongoing system maintenance and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51622C73N-A is determined by the following critical parameters:

Primary Compatibility 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 ratings: Minimum 600mA at 125V DC

Mechanical Compatibility Criteria:

• Operating position tolerance: ±0.050" from 0.602" (15.3mm)
• Operating force range: 150gf to 300gf
• Release force range: 20gf to 80gf

The Crouzet 83261642 qualifies as a substitute based on matching circuit configuration (SPST-NC), switch function (On-Mom), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.187"). The substitute meets or exceeds electrical requirements with 16A AC at 250V AC rating and maintains mechanical compatibility within acceptable operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261642 is a functionally equivalent substitute for the obsolete Panasonic AM51622C73N-A based on matching electrical circuit configuration, mechanical interface, and actuator characteristics. The substitute provides higher AC voltage rating (250V versus 125V), extending operational margin in applications where the original 125V specification is utilized. The Crouzet component is currently in active production status, ensuring availability for replacement and new implementations.

The substitute maintains compatibility with existing mechanical mounting and electrical termination interfaces. Operating force differential (240gf original versus 204gf substitute) and release force variation (40gf original versus 51gf substitute) remain within acceptable engineering tolerances for snap-action switch applications. The Crouzet device operates across an extended temperature range (-20°C to 125°C versus -25°C to 105°C), providing broader environmental compatibility.

Mechanical life specification differs significantly (1,000,000 cycles for Crouzet versus 10,000,000 cycles for Panasonic). Applications requiring extended mechanical cycling should evaluate this parameter against specific duty cycle requirements. The Crouzet component carries RoHS compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261642 directly replace the Panasonic AM51622C73N-A in existing assemblies?

A: Yes. Both components 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"). Mechanical and electrical parameters are compatible within standard engineering tolerances for snap-action switch applications.

Q: What is the significance of the voltage rating difference (125V versus 250V)?

A: The Crouzet substitute is rated for 250V AC, which exceeds the original 125V AC specification. This provides additional electrical margin and allows the substitute to operate safely in applications originally designed for 125V. The higher rating does not create incompatibility; it represents an enhanced capability.

Q: How do the operating force specifications compare?

A: The Panasonic original requires 240gf operating force, while the Crouzet substitute requires 204gf. This 36gf difference is within acceptable variation for snap-action switch applications and does not affect functional compatibility or actuator interface compatibility.

Q: What does the mechanical life specification difference mean for component selection?

A: The Panasonic original is rated for 10,000,000 mechanical cycles, while the Crouzet substitute is rated for 1,000,000 cycles. Applications with high-frequency cycling should evaluate whether the substitute's mechanical life rating meets specific duty cycle requirements. For standard industrial control applications with moderate cycling, the Crouzet rating is typically sufficient.

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

A: The Crouzet 83261642 carries RoHS compliance and REACH unaffected status. Both components share the same ECCN (EAR99) and HTSUS classification. The Crouzet component is in active production, ensuring ongoing availability and compliance with current regulatory standards.

Q: Does the operating temperature range difference affect substitution suitability?

A: The Crouzet substitute operates across -20°C to 125°C, compared to the original -25°C to 105°C. The substitute provides a higher upper temperature limit (125°C versus 105°C) but a slightly higher lower temperature limit (-20°C versus -25°C). For most industrial applications operating within standard environmental ranges, this difference is not significant.
