AM50663C33-A Equivalent & Substitute Parts

Part Overview

The AM50663C33-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 AC at 125V and 500mA DC at 125V, featuring a straight lever actuator and quick connect 0.187" (4.7mm) termination. The product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50663C33-A is determined by the following critical parameters:

Circuit configuration must remain SPST-NO to maintain functional equivalence in the application. Switch function must be Off-Mom (momentary action). Actuator type must be lever with straight orientation to ensure mechanical compatibility with existing panel layouts and operator interfaces. Mounting type must be chassis mount to fit existing mechanical enclosures. Termination style must be quick connect 0.187" (4.7mm) to maintain electrical connection compatibility.

Current and voltage ratings must meet or exceed the application requirements. The substitute part 831613A6.CB from Crouzet satisfies these core functional and mechanical criteria while providing enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 831613A6.CB serves as a direct functional substitute for the obsolete Panasonic AM50663C33-A. Both switches share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator geometry (lever, straight), mounting method (chassis mount), and termination style (quick connect 0.187"). The Crouzet part is currently in active production status, ensuring long-term availability and supply chain continuity.

The Crouzet substitute provides superior electrical performance with 16A AC rating at 250V compared to the original 6A at 125V, and extended mechanical life of 20,000,000 cycles versus 10,000,000 cycles. The operating temperature range extends to 125°C maximum, exceeding the original specification of 105°C. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification. The Crouzet part carries RoHS Compliant and REACH Unaffected certifications, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831613A6.CB directly replace the Panasonic AM50663C33-A in existing applications?

A: Yes. Both switches share identical circuit configuration (SPST-NO), switch function (Off-Mom momentary), actuator type (lever, straight), mounting type (chassis mount), and termination style (quick connect 0.187"). The Crouzet part meets or exceeds all electrical and mechanical specifications of the original.

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

A: The Crouzet substitute provides higher current capacity (16A AC at 250V versus 6A AC at 125V), extended mechanical life (20,000,000 cycles versus 10,000,000 cycles), and wider operating temperature range (-20°C to 125°C versus -25°C to 105°C). The Crouzet part is in active production while the Panasonic part is obsolete.

Q: Are the physical dimensions and mounting footprints identical?

A: Both switches feature identical mounting type (chassis mount) and termination style (quick connect 0.187"). Operating position and pretravel specifications are equivalent (approximately 0.600" to 0.602" and 0.296" to unspecified respectively), confirming mechanical compatibility in existing panel layouts.

Q: Do both switches meet current regulatory compliance standards?

A: The Crouzet 831613A6.CB carries RoHS Compliant and REACH Unaffected certifications. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and share EAR99 ECCN classification.

Q: What is the inventory status for these parts?

A: The Panasonic AM50663C33-A has 1,121 pieces in stock as new original inventory. The Crouzet 831613A6.CB has 965 pieces in stock as new original inventory, with active production status ensuring continued availability.
