AM51646C63N-A Equivalent & Substitute Parts

Part Overview

The AM51646C63N-A is a snap action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This component operates at 16A AC and 125V, featuring a lever roller actuator with momentary on-off functionality. The product is currently obsolete, necessitating identification of equivalent alternatives that maintain functional compatibility across critical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51646C63N-A is determined by strict alignment with the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Actuator type must be Lever with Roller
• Voltage rating (AC) must be 125V minimum
• Current rating (AC) must meet or exceed 16A

Two substitute parts meet these criteria with varying current ratings and operational characteristics:

BA-2RV22-D81 (Honeywell): Exceeds current rating at 20A AC, maintains all circuit and mechanical compatibility parameters.

TFS06SA1040C (C&K): Operates at reduced current rating of 6A AC, suitable only for applications where current demand does not exceed 6A.

Parameter Comparison

Engineering Selection Recommendations

BA-2RV22-D81 (Honeywell Sensing and Productivity Solutions) is the primary substitute for applications requiring full current capacity replacement. This part maintains electrical and mechanical compatibility while providing 20A AC rating, exceeding the original 16A specification. The component is active in production with RoHS compliance certification. Operating temperature range is reduced to -55°C to 85°C compared to the original -25°C to 105°C specification.

TFS06SA1040C (C&K) serves as a substitute only for applications where circuit current does not exceed 6A AC. This part is active in production with ROHS3 compliance and includes IP40 ingress protection. Operating temperature range is -40°C to 85°C. Mechanical life rating of 10,000,000 cycles matches the original specification.

Selection between these substitutes depends on application current requirements. The BA-2RV22-D81 provides direct replacement capability for full-load operation. The TFS06SA1040C is suitable only for reduced-current applications.

Frequently Asked Questions (FAQ)

Q: Can BA-2RV22-D81 directly replace AM51646C63N-A in all applications?

A: BA-2RV22-D81 maintains compatibility across circuit configuration, switch function, mounting type, termination style, and actuator type. The 20A AC rating exceeds the original 16A requirement. Operating temperature range is reduced to -55°C to 85°C; verify application temperature requirements do not exceed 85°C.

Q: Is TFS06SA1040C suitable as a general replacement?

A: TFS06SA1040C is suitable only for applications where AC current does not exceed 6A. The original AM51646C63N-A is rated for 16A AC; this substitute cannot be used in higher-current circuits.

Q: What are the key mechanical differences between these substitutes?

A: Operating force differs: AM51646C63N-A requires 180gf, BA-2RV22-D81 requires 170gf, and TFS06SA1040C requires 130gf. Release force also varies: 30gf (original), 43gf (Honeywell), and 20gf (C&K). Operating position and travel distances differ across all three parts.

Q: Are all substitutes RoHS compliant?

A: BA-2RV22-D81 is RoHS Compliant. TFS06SA1040C is ROHS3 Compliant. The original AM51646C63N-A product status is obsolete with no RoHS designation provided.

Q: What packaging options are available?

A: AM51646C63N-A is supplied in bulk packaging. BA-2RV22-D81 is supplied in bulk packaging. TFS06SA1040C is supplied in box packaging.
