AM51626C73N-A Equivalent & Substitute Parts

Part Overview

The AM51626C73N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as SPST-NC (Single Pole Single Throw - Normally Closed) with a 16A AC rating at 125V. This component features a lever/roller actuator 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51626C73N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NC to maintain identical electrical behavior
• Switch Function: Must be On-Mom (momentary action)
• Current Rating: Minimum 16A AC to support existing load requirements
• Voltage Rating: Minimum 125V AC to meet or exceed system voltage specifications
• Actuator Type: Lever/roller configuration for mechanical compatibility
• Mounting Type: Chassis mount with quick connect 0.187" (4.7mm) terminals for direct installation compatibility
• Operating Temperature Range: Must encompass or exceed -25°C to 105°C operational envelope

The Crouzet 83261647 satisfies all substitution criteria. While it operates at 250V AC (exceeding the 125V requirement), this represents a higher voltage rating and does not compromise compatibility. The 16A AC current rating matches the original specification. Mechanical parameters including actuator type, mounting configuration, and termination style are identical. The operating temperature range of -20°C to 125°C encompasses the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261647 is a direct functional equivalent for the obsolete AM51626C73N-A. Selection should be based on the following factors:

Product Availability: The Crouzet 83261647 carries active product status with 878 units in stock, ensuring supply chain continuity for the AM51626C73N-A, which is obsolete.

Electrical Compatibility: Both components share identical circuit configuration (SPST-NC), switch function (On-Mom), and current rating (16A AC). The Crouzet unit's 250V AC rating exceeds the 125V requirement, providing additional voltage margin without compromising system operation.

Mechanical Compatibility: Identical actuator type (lever/roller), mounting configuration (chassis mount), and termination style (quick connect 0.187") enable direct installation without mechanical redesign.

Compliance: The Crouzet 83261647 is RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements. Both components carry ECCN EAR99 classification and identical HTSUS codes (8536.50.9040).

Operational Envelope: The Crouzet unit's operating temperature range (-20°C to 125°C) encompasses the original specification, with extended upper temperature capability.

Mechanical Life Consideration: The Crouzet 83261647 specifies 1,000,000 mechanical cycles versus 10,000,000 for the original. Application-specific cycle requirements should be evaluated against this parameter.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261647 be used as a direct replacement for the AM51626C73N-A?

A: Yes. Both components share identical circuit configuration (SPST-NC), switch function (On-Mom), current rating (16A AC), actuator type (lever/roller), mounting type (chassis mount), and termination style (quick connect 0.187"). No circuit modifications or mechanical redesign is required.

Q: Why does the Crouzet part have a higher voltage rating (250V vs. 125V)?

A: Higher voltage ratings indicate the component's maximum safe operating voltage. A 250V-rated switch operates safely at 125V with additional voltage margin. This does not affect compatibility or performance in 125V applications.

Q: What is the significance of the different mechanical life ratings?

A: The AM51626C73N-A specifies 10,000,000 mechanical cycles while the Crouzet 83261647 specifies 1,000,000 cycles. Applications requiring cycle counts exceeding 1,000,000 should evaluate this parameter against actual operational requirements.

Q: Are there compliance differences between the two parts?

A: The Crouzet 83261647 is RoHS Compliant and REACH Unaffected. The AM51626C73N-A compliance status is not specified in available documentation. Both carry identical ECCN (EAR99) and HTSUS (8536.50.9040) classifications.

Q: What is the operating temperature difference?

A: The AM51626C73N-A operates from -25°C to 105°C. The Crouzet 83261647 operates from -20°C to 125°C. The Crouzet unit provides extended upper temperature capability but a slightly narrower lower temperature range. Applications operating below -20°C should verify compatibility.

Q: Are the quick connect terminals identical?

A: Yes. Both components use Quick Connect - 0.187" (4.7mm) termination, enabling direct connection without terminal modification or adapter requirements.
