AM50651C33-A Equivalent & Substitute Parts

Part Overview

The AM50651C33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device with a 6A AC rating at 125V. This component features a lever actuator with straight configuration and chassis mount termination using quick connect 0.187" (4.7mm) 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 AM50651C33-A is determined by the following mandatory parameters:

• Circuit configuration must be SPST-NC
• Switch function must be On-Momentary
• Current rating must support minimum 6A AC
• Actuator type must be Lever, Straight
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Electrical life must meet or exceed 100,000 cycles
• Mechanical life must meet or exceed 10,000,000 cycles

The Crouzet 831607B6.A satisfies all mandatory substitution criteria. While the Crouzet part specifies a higher AC voltage rating of 250V, this represents an enhanced capability that maintains backward compatibility with the original 125V AC requirement.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 831607B6.A is a direct functional equivalent for the obsolete AM50651C33-A. Both components share identical circuit configuration, current rating, actuator geometry, mounting interface, and termination style. The Crouzet part carries active product status, ensuring ongoing availability and supply chain continuity.

The Crouzet 831607B6.A is RoHS Compliant, whereas RoHS status is not specified for the Panasonic original. Both parts maintain REACH Unaffected status and carry identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications. The higher AC voltage rating of the Crouzet substitute (250V versus 125V) provides enhanced operational margin without compromising compatibility in applications designed for the original 125V specification.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831607B6.A directly replace the AM50651C33-A in existing applications?

A: Yes. Both components share identical circuit configuration (SPST-NC), current rating (6A AC), actuator type (Lever, Straight), mounting type (Chassis Mount), and termination style (Quick Connect - 0.187"). Physical and electrical interfaces are compatible.

Q: What is the significance of the higher voltage rating on the Crouzet part?

A: The Crouzet 831607B6.A is rated for 250V AC, compared to the original 125V AC rating. This higher rating indicates enhanced dielectric strength and represents a superset of the original specification. Applications designed for 125V operation remain fully compatible.

Q: Are there any compliance differences between the two parts?

A: The Crouzet 831607B6.A carries RoHS Compliant certification, while RoHS status is not specified for the Panasonic original. Both parts maintain REACH Unaffected status and identical trade classification codes (ECCN: EAR99; HTSUS: 8536.50.7000).

Q: What is the operating temperature range difference?

A: The AM50651C33-A operates from -25°C to 105°C, while the Crouzet 831607B6.A operates from -40°C to 85°C. Application-specific temperature requirements must be evaluated against these ranges.

Q: Are the mechanical and electrical life ratings equivalent?

A: Yes. Both components specify 100,000 electrical cycles and 10,000,000 mechanical cycles, indicating identical durability characteristics for the intended application.
