AM51633C63N-A Equivalent & Substitute Parts

Part Overview

The AM51633C63N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with a 16A AC / 600mA DC current rating at 125V. This chassis-mounted switch features a straight lever actuator with quick-connect 0.187" (4.7mm) termination and is rated for 100,000 electrical cycles and 10,000,000 mechanical cycles. The product is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for applications requiring SPST-NO snap-action switching functionality with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51633C63N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary)
• Actuator type must be Lever, Straight
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Current rating (AC) must be equal to or greater than 16A
• Voltage rating (AC) must be equal to or greater than 125V
• Operating temperature range must encompass or exceed -25°C to 105°C

Two substitute parts meet these criteria with varying degrees of parameter alignment:

LS0851503F040C1C (E-Switch): Meets all critical substitution parameters with identical mechanical configuration and termination. Current rating is 15A AC, which is 1A below the original specification. Voltage rating matches at 125V AC. Operating temperature range is -25°C to 85°C, which does not fully encompass the upper limit of the original specification (105°C).

83261843 (Crouzet): Meets all critical substitution parameters with identical mechanical configuration and termination. Current rating exceeds specification at 16A AC. Voltage rating exceeds specification at 250V AC. Operating temperature range is -20°C to 125°C, which exceeds the original specification in the upper range but does not reach the lower limit of -25°C.

Parameter Comparison

Engineering Selection Recommendations

LS0851503F040C1C (E-Switch): This part is actively manufactured and available. It provides direct mechanical and electrical compatibility with the original AM51633C63N-A in terms of circuit configuration, switch function, actuator type, mounting, and termination. The 15A AC current rating is 1A below the original specification; applications operating at or below 15A AC are suitable for this substitute. The operating temperature range of -25°C to 85°C does not extend to the original upper limit of 105°C; applications requiring operation above 85°C are not suitable for this substitute. Electrical life is rated at 50,000 cycles, which is half the original specification.

83261843 (Crouzet): This part is actively manufactured and available. It provides direct mechanical and electrical compatibility with the original AM51633C63N-A in terms of circuit configuration, switch function, actuator type, mounting, and termination. The 16A AC current rating matches the original specification. The 250V AC voltage rating exceeds the original 125V specification, providing additional voltage margin. The operating temperature range of -20°C to 125°C exceeds the original upper limit but does not reach the original lower limit of -25°C; applications requiring operation below -20°C are not suitable for this substitute.

Frequently Asked Questions (FAQ)

Q: Can LS0851503F040C1C be used as a direct replacement for AM51633C63N-A?

A: LS0851503F040C1C is mechanically and functionally compatible with AM51633C63N-A for SPST-NO momentary switching applications. However, the 15A AC current rating is 1A below the original specification, and the maximum operating temperature of 85°C does not reach the original 105°C limit. Substitution is appropriate only for applications operating within these reduced parameters.

Q: Can 83261843 be used as a direct replacement for AM51633C63N-A?

A: 83261843 is mechanically and functionally compatible with AM51633C63N-A for SPST-NO momentary switching applications. The 16A AC current rating and 250V AC voltage rating meet or exceed the original specifications. However, the minimum operating temperature of -20°C does not reach the original -25°C limit. Substitution is appropriate for applications operating within -20°C to 125°C.

Q: What are the key differences in mechanical life between these parts?

A: The original AM51633C63N-A is rated for 10,000,000 mechanical cycles. Both substitute parts (LS0851503F040C1C and 83261843) are rated for 1,000,000 mechanical cycles. Applications requiring extended mechanical life beyond 1,000,000 cycles may not be suitable for these substitutes.

Q: Are both substitute parts RoHS compliant?

A: LS0851503F040C1C is ROHS3 Compliant. 83261843 compliance status is not specified in the provided data. Verify RoHS compliance requirements with your application specifications.

Q: What is the packaging format for each substitute part?

A: LS0851503F040C1C is supplied in Bulk packaging. 83261843 packaging format is not specified in the provided data. Confirm packaging requirements with your procurement specifications.
