AM50664C33-A Equivalent & Substitute Parts

Part Overview

The AM50664C33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with chassis mount termination. This component is rated for 6A AC at 125V and features a lever with simulated roller actuator. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50664C33-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Current rating (AC) must meet or exceed 6A
• Voltage rating (AC) must meet or exceed 125V
• Voltage rating (DC) must meet or exceed 125V

Secondary Mechanical Criteria:

• Actuator type: Lever configuration (simulated roller or straight acceptable)
• Operating temperature range must encompass the application requirements
• Electrical and mechanical life ratings must support intended duty cycle

Two substitute parts meet these criteria: TFCGK6ST1440Y (C&K) and V7-2B27D8-022 (Honeywell Sensing and Productivity Solutions). Both maintain SPST-NO configuration, Off-Mom function, chassis mount design, and Quick Connect termination. Both exceed the current and voltage requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

TFCGK6ST1440Y (C&K) is an active product with elevated current capacity (11A AC) and extended voltage rating (277V AC), providing margin above the original specification. This part maintains identical actuator configuration (lever with simulated roller) and termination style. The operating temperature range (-40°C to 85°C) is narrower than the original part; applications requiring operation below -25°C or above 85°C are not suitable for this substitute. This part is RoHS3 Compliant and REACH Affected.

V7-2B27D8-022 (Honeywell Sensing and Productivity Solutions) is an active product with elevated current capacity (11A AC) and matching voltage rating (125V AC/DC). This part features a straight lever actuator rather than simulated roller, representing a mechanical variation. The operating temperature range (-40°C to 85°C) is narrower than the original part. Electrical and mechanical life ratings match the original specification. This part is RoHS Compliant.

Both substitutes are suitable for applications operating within -40°C to 85°C temperature range. Selection between them depends on actuator preference (simulated roller versus straight lever) and compliance requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can TFCGK6ST1440Y or V7-2B27D8-022 be used as direct replacements for AM50664C33-A?

A: Both parts meet the core electrical and mechanical substitution criteria: SPST-NO configuration, Off-Mom function, 6A+ AC current capacity, 125V+ AC voltage rating, chassis mount design, and Quick Connect 0.187" termination. Physical mounting and electrical connection are compatible. Verify that the application operating temperature range does not exceed -40°C to 85°C, as both substitutes have a narrower temperature range than the original part.

Q: What is the primary difference between TFCGK6ST1440Y and V7-2B27D8-022?

A: TFCGK6ST1440Y features a lever with simulated roller actuator and supports 277V AC operation, while V7-2B27D8-022 features a straight lever actuator and is rated for 125V AC. Both support 11A AC current. The choice depends on actuator mechanical preference and voltage requirements of the application.

Q: Why does the operating temperature range differ between the original part and the substitutes?

A: The AM50664C33-A operates from -25°C to 105°C, while both substitutes operate from -40°C to 85°C. The substitutes provide extended low-temperature capability but reduced high-temperature capability. Confirm that the application does not require operation above 85°C.

Q: Are there compliance or certification differences between the substitute parts?

A: TFCGK6ST1440Y is RoHS3 Compliant and REACH Affected. V7-2B27D8-022 is RoHS Compliant. Both are classified as EAR99 for export control purposes. Verify compliance requirements specific to your application and region.

Q: What is the packaging format for these substitute parts?

A: Both TFCGK6ST1440Y and V7-2B27D8-022 are supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.
