AM51640C73N-A Equivalent & Substitute Parts

Part Overview

The AM51640C73N-A is a snap action switch manufactured by Panasonic Electric Works, featuring SPDT (Single Pole Double Throw) circuit configuration with On-Momentary switch function. This component is rated for 16A AC at 125V and utilizes a round pin plunger actuator with chassis mount configuration. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51640C73N-A is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Actuator type must be round pin plunger
• Mounting type must be chassis mount
• Current and voltage ratings must meet or exceed application requirements
• Termination style compatibility with existing connections

Two substitute parts have been identified based on these criteria:

Group 1 - Current Rating Match (16A AC): Crouzet 83261103 maintains the 16A AC current rating with higher voltage capability (250V AC) and identical termination style (0.187" Quick Connect).

Group 2 - Voltage Rating Match (250V AC): Crouzet 83161806 provides higher voltage rating (250V AC) but with reduced current capacity (5A AC), suitable for lower-current applications within the same voltage envelope.

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83261103 is the primary substitute for applications requiring 16A AC current capacity. This part maintains identical current rating and operating force characteristics while providing enhanced voltage capability (250V AC versus 125V AC). The termination style matches the original component (0.187" Quick Connect), enabling direct mechanical and electrical integration. Product status is active with RoHS compliance certification.

Crouzet 83161806 is suitable only for applications with current requirements not exceeding 5A AC. While this part offers extended temperature range (-60°C to 150°C) and superior mechanical life (20,000,000 cycles), the reduced current capacity and different termination style (0.250" Quick Connect) require circuit redesign and connector modification. Product status is active with RoHS compliance certification.

For applications requiring the full 16A AC rating of the original AM51640C73N-A, Crouzet 83261103 is the appropriate selection. For lower-current applications, Crouzet 83161806 may be considered with connector compatibility assessment.

Frequently Asked Questions (FAQ)

Q: Can Crouzet 83261103 directly replace AM51640C73N-A in all applications?

A: Direct replacement is possible for applications operating at or below 16A AC. The 83261103 provides higher voltage rating (250V AC) and maintains identical termination style (0.187" Quick Connect) and operating force (400gf). Mechanical mounting and electrical connection compatibility should be confirmed for specific applications.

Q: What is the primary limitation of Crouzet 83161806 as a substitute?

A: The 83161806 is limited to 5A AC current capacity, making it unsuitable for applications requiring the full 16A AC rating of the original part. Additionally, the termination style differs (0.250" Quick Connect versus 0.187"), requiring connector modification.

Q: Are both substitute parts RoHS compliant?

A: Yes, both Crouzet parts (83261103 and 83161806) are RoHS compliant. The original Panasonic AM51640C73N-A RoHS status is not specified in available documentation.

Q: How do the mechanical life ratings compare?

A: The AM51640C73N-A specifies 10,000,000 mechanical cycles. Crouzet 83261103 provides 1,000,000 cycles, while Crouzet 83161806 provides 20,000,000 cycles. Application duty cycle requirements should determine acceptability.

Q: What is the operating temperature range difference?

A: The original part operates from -25°C to 105°C. Crouzet 83261103 extends this to -20°C to 125°C. Crouzet 83161806 provides the widest range at -60°C to 150°C. Temperature environment requirements should guide selection.

Q: Can termination style differences be accommodated?

A: Crouzet 83261103 uses identical 0.187" Quick Connect termination, enabling direct connection. Crouzet 83161806 uses 0.250" Quick Connect termination, requiring connector replacement or circuit board modification.
