AM51653C63N-A Equivalent & Substitute Parts

Part Overview

The AM51653C63N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device rated for 16A at 125V AC. This component features a lever actuator with straight configuration and chassis mount termination using quick-connect 0.187" terminals. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51653C63N-A is determined by the following mandatory parameters:

• Circuit configuration must be SPST-NC
• Switch function must be On-Mom (momentary)
• Actuator type must be lever with straight configuration
• Mounting type must be chassis mount
• Termination style must be quick-connect 0.187" (4.7mm)
• Current rating must meet or exceed 16A AC
• Voltage rating must meet or exceed 125V AC
• Operating temperature range must encompass the application requirements

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

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83261643: This substitute provides full electrical compatibility with the AM51653C63N-A, matching the 16A AC current rating and exceeding the voltage requirement at 250V AC. The device is currently in active production status. The operating temperature range extends to 125°C, providing broader thermal coverage than the original part. Mechanical life is reduced to 1,000,000 cycles compared to the original 10,000,000 cycles. RoHS compliance and REACH unaffected status are confirmed.

E-Switch LS0851503F025C1B: This substitute meets the core circuit and mechanical requirements with SPST-NC configuration and momentary function. The current rating is specified at 15A AC, which is 1A below the original 16A specification. Voltage rating matches at 125V AC. The operating temperature range is limited to -25°C to 85°C, which is 20°C below the original upper limit. Mechanical life is 1,000,000 cycles. The device is in active production with ROHS3 compliance and REACH unaffected status. This part is also listed as an original substitute in the AM51653 base product documentation.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261643 be used as a direct replacement for the AM51653C63N-A?

A: Yes. The Crouzet part maintains identical circuit configuration (SPST-NC), switch function (On-Mom), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick-connect 0.187"). Current and voltage ratings meet or exceed the original specification. Mechanical life is lower at 1,000,000 cycles versus 10,000,000 cycles.

Q: What is the primary limitation of the E-Switch LS0851503F025C1B as a substitute?

A: The current rating is specified at 15A AC, which is 1A below the original 16A AC requirement. Additionally, the upper operating temperature limit is 85°C, compared to 105°C for the original part. Electrical life is 50,000 cycles versus 100,000 cycles. These parameters must be evaluated against application requirements.

Q: Are both substitute parts RoHS compliant?

A: The Crouzet 83261643 is RoHS compliant. The E-Switch LS0851503F025C1B is ROHS3 compliant. Both parts are REACH unaffected.

Q: What is the mechanical life difference between the original and substitute parts?

A: The AM51653C63N-A specifies 10,000,000 mechanical cycles. Both substitute parts specify 1,000,000 mechanical cycles, representing a tenfold reduction in rated mechanical life.

Q: Can the E-Switch part be used in applications requiring 16A at 125V?

A: The E-Switch LS0851503F025C1B is rated for 15A AC at 125V. Applications requiring the full 16A specification should use the Crouzet 83261643 or identify alternative sources for the original Panasonic part.
