AM50642C33-A Equivalent & Substitute Parts

Part Overview

The AM50642C33-A is a snap action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This switch is rated for 6A AC at 125V and features a straight lever actuator with momentary on-off functionality. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM50642C33-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Actuator type must be Lever, Straight
• Voltage rating must support minimum 125V AC operation

Secondary Compatibility Considerations:

• Current rating must meet or exceed 6A AC at 125V
• Operating temperature range should encompass or overlap the original -25°C to 105°C specification
• Electrical and mechanical life ratings should be evaluated based on application duty cycle requirements

The substitute part LS0851502F120C1A from E-Switch meets all primary compatibility criteria and exceeds the current rating specification at 15A AC, making it suitable for direct substitution in applications where the original AM50642C33-A is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The LS0851502F120C1A is an active product from E-Switch and represents the primary substitute for the obsolete AM50642C33-A. Both parts share identical circuit configuration, switch function, actuator type, mounting method, and termination style, ensuring mechanical and electrical compatibility in chassis mount applications.

The E-Switch substitute provides superior current handling capability at 15A AC compared to the original 6A AC rating, allowing for use in applications with higher current demands. Both parts maintain REACH compliance and EAR99 export classification.

The operating temperature range of the substitute extends to 85°C maximum, which is 20°C lower than the original specification. Applications requiring operation above 85°C should be evaluated for thermal management or alternative solutions. The electrical life rating of 50,000 cycles is half that of the original part; applications with high-cycle duty should assess whether this reduction impacts long-term reliability requirements. The mechanical life of 1,000,000 cycles remains suitable for most industrial control applications.

Frequently Asked Questions (FAQ)

Q: Can the LS0851502F120C1A directly replace the AM50642C33-A in existing designs?

A: Yes, the LS0851502F120C1A is mechanically and electrically compatible for direct substitution. Both parts feature identical SPDT circuit configuration, on-momentary function, straight lever actuator, chassis mount design, and 0.187" quick connect termination. The substitute's higher current rating of 15A AC exceeds the original 6A AC specification, providing additional capacity margin.

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

A: The primary differences are product status (original is obsolete, substitute is active), current rating (6A versus 15A AC), operating temperature maximum (105°C versus 85°C), electrical life (100,000 versus 50,000 cycles), and mechanical life (10,000,000 versus 1,000,000 cycles). Both maintain identical mechanical interfaces and electrical circuit topology.

Q: Are there packaging or inventory considerations for the substitute part?

A: The LS0851502F120C1A is supplied in bulk packaging with 995 pieces currently in stock, compared to the original part's 709 pieces. Bulk packaging may require adjustment to procurement and storage procedures depending on application volume requirements.

Q: Does the lower maximum operating temperature of the substitute affect compatibility?

A: The substitute's 85°C maximum operating temperature is 20°C lower than the original 105°C specification. Applications operating continuously above 85°C should be evaluated for thermal conditions and potential derating requirements. Most industrial control applications operate well within this temperature envelope.

Q: Are both parts compliant with regulatory requirements?

A: Yes, both the AM50642C33-A and LS0851502F120C1A are REACH unaffected and classified as EAR99 for export purposes. The substitute is RoHS3 compliant, meeting current environmental and hazardous substance restrictions.
