AM50651D33-A Equivalent & Substitute Parts

Part Overview

The AM50651D33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device with chassis mount installation. This switch is rated for 6A at 125V AC and features a straight lever actuator with quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and design continuity in applications requiring SPST-NC snap-action switching.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50651D33-A is determined by the following critical parameters:

• Circuit configuration must remain SPST-NC
• Switch function must be On-Momentary
• Actuator type must be Lever, Straight
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.250" (6.3mm)
• Current rating must support minimum 6A AC operation
• Voltage rating must support minimum 125V AC operation
• Electrical life must meet or exceed 100,000 cycles
• Mechanical life must meet or exceed 10,000,000 cycles

The Crouzet 831607B3.A satisfies these substitution criteria. While it features a higher AC voltage rating (250V) and different operating temperature range (-40°C to 85°C), these parameters represent equal or superior capability and do not prevent functional equivalence in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 831607B3.A is a direct functional equivalent for the obsolete AM50651D33-A. Selection should be based on the following factors:

Product Availability: The Crouzet part maintains active product status with current manufacturing support, whereas the Panasonic part is obsolete. For new designs or ongoing production requirements, the Crouzet alternative ensures supply chain continuity.

Compliance and Certification: The Crouzet 831607B3.A carries RoHS Compliance certification, providing environmental regulatory alignment for applications subject to RoHS requirements. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Electrical Performance: The Crouzet substitute provides equivalent AC current rating (6A) and exceeds the voltage requirement with a 250V AC rating compared to the original 125V AC specification. This higher voltage rating does not compromise functionality in 125V AC applications.

Operating Environment: The Crouzet part operates across -40°C to 85°C, which is narrower than the original -25°C to 105°C range. Applications requiring operation at temperatures below -40°C or above 85°C must retain the original Panasonic specification or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831607B3.A directly replace the AM50651D33-A in existing assemblies?

A: Yes, provided the operating temperature range of -40°C to 85°C is compatible with the application. The circuit configuration, switch function, actuator type, mounting method, and termination style are identical. The higher voltage rating of the Crouzet part does not prevent substitution in 125V AC circuits.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Crouzet is active; Panasonic is obsolete), voltage rating (Crouzet 250V AC vs. Panasonic 125V AC), operating temperature range (Crouzet -40°C to 85°C vs. Panasonic -25°C to 105°C), and compliance certifications (Crouzet includes RoHS Compliance). All switching characteristics and mechanical specifications remain equivalent.

Q: Are there any mechanical compatibility concerns with the quick-connect termination?

A: No. Both parts use identical Quick Connect - 0.250" (6.3mm) termination, ensuring direct compatibility with existing connector interfaces and wiring harnesses.

Q: Which part should be selected for new designs?

A: The Crouzet 831607B3.A should be selected for new designs due to its active product status, ensuring long-term availability and manufacturing support. The Panasonic AM50651D33-A is obsolete and should not be specified for new applications.

Q: Does the higher voltage rating of the Crouzet part affect performance in 125V AC applications?

A: No. A higher voltage rating indicates the component can safely operate at higher voltages without degradation. In 125V AC applications, the Crouzet part operates well within its rated specification and performs identically to the original part.
