AM50635D33-A Equivalent & Substitute Parts

Part Overview

The AM50635D33-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 features a lever/roller actuator with off-momentary switching function. The product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50635D33-A is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO
• Switch function must be Off-Momentary
• Actuator type must be Lever/Roller
• 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 AC @ 125V)
• Operating temperature range must encompass or exceed -25°C to 105°C

The substitute part 831613A3.EB from Crouzet meets these core functional and mechanical requirements while offering enhanced electrical ratings and improved mechanical durability.

Parameter Comparison

Engineering Selection Recommendations

The 831613A3.EB from Crouzet is a direct functional substitute for the obsolete AM50635D33-A. The Crouzet part maintains identical circuit topology, switch function, actuator configuration, mounting method, and termination style. The substitute provides superior electrical ratings (16A AC @ 250V versus 6A AC @ 125V), extended mechanical life (20,000,000 cycles versus 10,000,000 cycles), and active product status ensuring continued availability.

The Crouzet part is RoHS Compliant and carries REACH Unaffected certification, meeting modern regulatory requirements. Both parts share ECCN EAR99 classification. The operating temperature range of the substitute (-20°C to 125°C) encompasses the original specification with extended upper temperature capability.

Physical dimensions remain compatible, with operating position variance of 0.009" (0.2mm) representing negligible mechanical difference in chassis-mounted applications.

Frequently Asked Questions (FAQ)

Q: Can the 831613A3.EB directly replace the AM50635D33-A in existing applications?

A: Yes. Both switches share identical circuit configuration (SPST-NO), switch function (Off-Momentary), actuator type (Lever/Roller), mounting method (Chassis Mount), and termination style (Quick Connect - 0.250"). Physical dimensions are compatible. The substitute provides higher current and voltage ratings, making it suitable for the original application envelope.

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

A: The primary differences are current rating (16A AC @ 250V versus 6A AC @ 125V), mechanical life (20,000,000 versus 10,000,000 cycles), operating force (82gf versus 60gf), and product status (Active versus Obsolete). The Crouzet part offers enhanced performance specifications across all measurable parameters.

Q: Are there compatibility concerns with the higher operating force of the substitute?

A: The operating force difference (82gf versus 60gf) represents a 22gf increase. This affects actuator engagement force but does not impact electrical compatibility or mounting compatibility. System design must accommodate the increased actuation force requirement.

Q: Does the substitute meet current regulatory compliance standards?

A: Yes. The 831613A3.EB is RoHS Compliant and REACH Unaffected, meeting current regulatory requirements. The original AM50635D33-A carries REACH Unaffected status but predates RoHS implementation.

Q: What is the significance of the operating position difference?

A: The operating position variance is 0.009" (0.2mm), representing less than 1% difference. This is negligible for chassis-mounted applications and does not affect functional compatibility or mechanical fit.

Q: Is the extended temperature range of the substitute beneficial?

A: The Crouzet substitute operates from -20°C to 125°C compared to the original -25°C to 105°C. The upper temperature capability is extended by 20°C, providing improved performance margin in elevated temperature environments. The lower temperature limit differs by 5°C, which is typically insignificant for most industrial applications.
