AM50663D33-A Equivalent & Substitute Parts

Part Overview

The AM50663D33-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 switch is rated for 6A at 125V AC and features a straight lever actuator with quick connect 0.250" (6.3mm) termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and design continuity applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50663D33-A is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Actuator type must be Lever, Straight
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect - 0.250" (6.3mm)
• Current and voltage ratings must meet or exceed the original specification (minimum 6A @ 125V AC)
• Operating temperature range must encompass or exceed -25°C to 105°C

The substitute parts listed below satisfy these core electrical and mechanical compatibility criteria. Both Crouzet alternatives maintain identical circuit topology, actuator configuration, and termination interface, enabling direct functional replacement in applications requiring SPST-NO momentary switching with chassis-mounted quick connect terminals.

Parameter Comparison

Engineering Selection Recommendations

Both Crouzet alternatives (831613A3.DB and 831614A3.DB) are active products with current manufacturing support, providing supply chain continuity for the obsolete AM50663D33-A. Both substitutes exceed the original electrical specifications with higher voltage ratings (250V AC versus 125V AC) and superior mechanical life ratings (20,000,000 and 30,000,000 cycles respectively, compared to 10,000,000 cycles).

The 831614A3.DB offers the closest electrical match to the original specification with 10A @ 250V AC rating and identical 15gf operating force. This part maintains the same mechanical life advantage while providing expanded voltage capability.

The 831613A3.DB provides maximum electrical headroom with 16A @ 250V AC rating and extended mechanical life to 20,000,000 cycles, suitable for applications requiring higher current capacity or extended service intervals.

Both Crouzet parts are RoHS Compliant and REACH Unaffected, meeting modern regulatory requirements. The operating temperature range of -20°C to 125°C on both substitutes encompasses the original -25°C to 105°C specification, with extended upper temperature capability.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831614A3.DB directly replace the AM50663D33-A in existing applications?

A: Yes. The 831614A3.DB maintains identical circuit topology (SPST-NO), switch function (Off-Mom), actuator type (Lever, Straight), mounting configuration (Chassis Mount), and termination interface (Quick Connect - 0.250"). Electrical ratings exceed the original specification, and operating position dimensions are equivalent (0.600" versus 0.602").

Q: What is the primary difference between the two Crouzet substitutes?

A: The 831613A3.DB is rated for 16A @ 250V AC with 20,000,000 cycle mechanical life. The 831614A3.DB is rated for 10A @ 250V AC with 30,000,000 cycle mechanical life. The 831614A3.DB matches the original 15gf operating force, while the 831613A3.DB requires 23gf.

Q: Are the Crouzet parts compatible with the original quick connect terminals?

A: Yes. Both Crouzet parts use identical Quick Connect - 0.250" (6.3mm) termination, ensuring direct compatibility with existing wiring harnesses and connector interfaces.

Q: Do the substitute parts meet current regulatory standards?

A: Yes. Both Crouzet alternatives are RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the operating temperature capability of the substitutes compared to the original?

A: The original AM50663D33-A operates from -25°C to 105°C. Both Crouzet substitutes operate from -20°C to 125°C, providing extended upper temperature capability. The lower temperature limit differs by 5°C; applications requiring operation below -20°C require verification of thermal performance.
