AM51633C73N-A Equivalent & Substitute Parts

Part Overview

The AM51633C73N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with chassis mount installation. This switch is rated for 16A at 125V AC and features a straight lever actuator with quick connect termination. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51633C73N-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Actuator type: Lever, Straight
• Mounting type: Chassis Mount
• Termination style: Quick Connect - 0.187" (4.7mm)

Electrical Compatibility Criteria:

• Current rating must meet or exceed 15A AC minimum
• Voltage rating must support 125V AC operation
• Operating temperature range must encompass the application environment

Mechanical Compatibility Criteria:

• Operating position tolerance within 0.602" ± 0.050" (15.3mm ± 1.3mm)
• Pretravel and differential travel characteristics must be compatible with mechanical linkage design

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

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83261843: This substitute provides the highest electrical rating compatibility with 16A AC current capacity and 250V AC voltage rating, exceeding the original specification. The part is currently in active production status with RoHS compliance certification. Operating temperature range extends to 125°C, providing broader thermal envelope coverage. Mechanical life specification of 1,000,000 cycles is lower than the original part. This option is suitable for applications where voltage margin and active product support are prioritized.

E-Switch LS0851503F040C1C: This substitute matches the original voltage rating of 125V AC with a current rating of 15A AC, meeting minimum electrical requirements. The part is in active production with ROHS3 compliance and REACH unaffected status. Operating temperature range is limited to -25°C to 85°C, which is narrower than the original specification. Mechanical life is 1,000,000 cycles. This option is suitable for applications operating within the specified temperature range where cost and active product availability are considerations.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261843 be used in place of the AM51633C73N-A? A: Yes. The Crouzet part maintains SPST-NO circuit configuration, Off-Mom function, straight lever actuator, chassis mount installation, and 0.187" quick connect termination. Current and voltage ratings exceed the original specification. Operating position variance is 0.004" (0.1mm), which is within acceptable mechanical tolerance. Verify that the application environment does not require the original 10,000,000 cycle mechanical life specification.

Q: Can the E-Switch LS0851503F040C1C be used in place of the AM51633C73N-A? A: Yes. The E-Switch part maintains SPST-NO circuit configuration, Off-Mom function, straight lever actuator, chassis mount installation, and 0.187" quick connect termination. Current rating is 15A AC, which meets the minimum requirement. Voltage rating matches at 125V AC. Operating position is identical at 0.602" (15.3mm). Confirm that the application environment operates within the -25°C to 85°C temperature range and does not require the original 10,000,000 cycle mechanical life specification.

Q: What are the key differences between the two substitute parts? A: The Crouzet 83261843 provides higher voltage rating (250V vs. 125V) and extended upper temperature limit (125°C vs. 85°C), making it suitable for higher-voltage or higher-temperature applications. The E-Switch LS0851503F040C1C provides exact voltage matching (125V) and identical operating position, making it suitable for direct replacement in standard 125V applications. Both parts have identical mechanical life ratings of 1,000,000 cycles, which is lower than the original 10,000,000 cycles.

Q: Are there any compliance or certification differences? A: The Crouzet 83261843 carries RoHS compliance certification and REACH unaffected status. The E-Switch LS0851503F040C1C carries ROHS3 compliance certification and REACH unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8536.50.9040, matching the original part classification.

Q: What packaging options are available? A: The Crouzet 83261843 is available in standard packaging. The E-Switch LS0851503F040C1C is available in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
