AM51631C63N-A Equivalent & Substitute Parts

Part Overview

The AM51631C63N-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 rating at 125V. This component features a lever actuator with straight configuration and chassis mount termination using quick connect 0.187" terminals. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51631C63N-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Current rating must support minimum 16A AC
• Voltage rating must support minimum 125V AC
• Actuator type must be lever with straight configuration
• Mounting type must be chassis mount
• Termination style must be quick connect 0.187" (4.7mm)

The Crouzet 83261842 meets all substitution criteria. While it features a higher voltage rating (250V AC) and different mechanical specifications, these parameters represent enhanced or equivalent capability within the allowed substitution envelope for this product category.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261842 is a direct functional substitute for the obsolete AM51631C63N-A. Selection between these components should be based on the following factors:

The Crouzet 83261842 is currently in active production status, ensuring long-term availability and supply chain continuity. The component carries RoHS compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The Crouzet substitute provides enhanced voltage rating capability (250V AC versus 125V AC), which permits operation in higher voltage applications while maintaining compatibility with 125V AC circuits. The extended upper operating temperature limit (125°C versus 105°C) accommodates thermal environments at the upper boundary of the original specification.

The mechanical life specification of the Crouzet component (1,000,000 cycles) is lower than the original Panasonic part (10,000,000 cycles). This difference should be evaluated against application duty cycle requirements to determine suitability for the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261842 directly replace the AM51631C63N-A in existing applications?

A: Yes, the Crouzet 83261842 meets all critical substitution parameters: identical circuit configuration (SPST-NO), switch function (Off-Mom), current rating (16A AC), actuator type (lever straight), mounting type (chassis mount), and termination style (quick connect 0.187"). The higher voltage rating and extended temperature range represent enhanced capability compatible with the original application envelope.

Q: What is the significance of the mechanical life difference between these components?

A: The AM51631C63N-A specifies 10,000,000 mechanical cycles, while the Crouzet 83261842 specifies 1,000,000 cycles. This tenfold difference reflects different design approaches. Applications requiring high-cycle operation should evaluate whether the Crouzet component meets the specific duty cycle requirements of the intended use.

Q: Are there compliance or certification differences between these parts?

A: The Crouzet 83261842 carries RoHS compliance and REACH unaffected status certifications. The AM51631C63N-A, being an older Panasonic component, does not list these certifications in the provided specifications. Both components share the same ECCN (EAR99) and HTSUS classification.

Q: What is the impact of the voltage rating difference?

A: The Crouzet component is rated for 250V AC, compared to the original 125V AC rating. This higher rating permits the component to operate safely in higher voltage circuits while remaining fully compatible with 125V AC applications. No derating or additional considerations are required for 125V AC operation.

Q: How do the operating temperature ranges compare?

A: The AM51631C63N-A operates from -25°C to 105°C, while the Crouzet 83261842 operates from -20°C to 125°C. The Crouzet component provides a 20°C higher upper temperature limit, suitable for thermal environments at the boundary of the original specification. The lower temperature limit difference (-20°C versus -25°C) is negligible for most industrial applications.
