AM51622C63N-A Equivalent & Substitute Parts

Part Overview

The AM51622C63N-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/DC. This component features a lever actuator with straight configuration and chassis mount termination using quick-connect 0.187" terminals. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51622C63N-A is determined by the following critical parameters:

Mandatory 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)

Allowable Parameter Variations:

• Voltage rating (AC): Substitute must equal or exceed 125V
• Current rating (AC): Substitute must equal or exceed 16A
• Operating temperature range: Substitute must encompass or exceed -25°C to 105°C
• Mechanical life: Substitute must meet or exceed 10,000,000 cycles

The Crouzet 83261642 satisfies all mandatory matching criteria and allowable parameter variations, qualifying it as a direct functional substitute despite differences in operating force, release force, and differential travel specifications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261642 is qualified as a functional substitute for the obsolete AM51622C63N-A based on the following factors:

Electrical Compatibility: Both components share identical circuit configuration (SPST-NC), switch function (On-Mom), current rating (16A AC), and termination style (Quick Connect - 0.187"). The Crouzet unit provides higher AC voltage rating (250V versus 125V), ensuring compatibility in applications operating at or below 125V.

Mechanical Compatibility: Both switches feature lever straight actuators with chassis mount configuration, enabling direct mechanical interchange in existing installations.

Compliance Status: The Crouzet 83261642 is classified as active product status with RoHS compliance and REACH unaffected designation, providing assurance of ongoing availability and regulatory alignment.

Operational Considerations: The Crouzet substitute exhibits higher operating force (204gf versus 180gf) and release force (51gf versus 30gf), which may affect tactile feedback and actuation characteristics. The Crouzet unit supports extended upper operating temperature (125°C versus 105°C) but provides reduced mechanical life (1,000,000 cycles versus 10,000,000 cycles).

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261642 directly replace the AM51622C63N-A in existing applications?

A: Yes, provided the application operates at or below 125V AC and does not require the full 10,000,000 cycle mechanical life specification. The identical circuit configuration, actuator type, mounting method, and termination style ensure mechanical and electrical compatibility.

Q: What is the significance of the higher voltage rating on the Crouzet substitute?

A: The Crouzet 83261642 is rated for 250V AC, compared to the original 125V AC rating. This higher rating does not affect compatibility in 125V applications; it indicates the substitute can safely operate in higher voltage environments if required.

Q: How do the differences in operating force and release force affect substitution?

A: The Crouzet unit requires 204gf operating force and 51gf release force, compared to 180gf and 30gf respectively for the original. These differences may result in slightly different tactile feedback and actuation characteristics. Applications sensitive to actuation force should be evaluated for compatibility.

Q: Why does the Crouzet substitute have lower mechanical life?

A: The Crouzet 83261642 specifies 1,000,000 cycles mechanical life versus 10,000,000 cycles for the original AM51622C63N-A. Applications requiring extended cycle life should assess whether the reduced specification meets operational requirements.

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

A: The Crouzet 83261642 is RoHS compliant and REACH unaffected, providing regulatory assurance. The original AM51622C63N-A is classified as obsolete. Both components share the same ECCN (EAR99) and HTSUS classification.

Q: What termination compatibility should be verified during installation?

A: Both components use Quick Connect - 0.187" (4.7mm) termination, ensuring direct compatibility with existing connector systems. No termination adapter or modification is required.
