Equivalent & Substitute Parts for AM50652C33-A

Part Overview

The AM50652C33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device rated for 6A at 125V AC and 500mA at 125V DC. This chassis-mount switch features a straight lever actuator with quick-connect 0.187" termination and is designed for momentary on operation. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM50652C33-A are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: SPST-NC
• Switch function: On-Mom (momentary operation)
• Actuator type: Lever, straight
• Mounting type: Chassis mount
• Current rating: 6A AC minimum
• Termination style: Quick connect

Voltage Consideration: The AM50652C33-A operates at 125V AC/DC. Substitute parts rated for higher voltages (250V AC) are electrically compatible for this application, as they can safely operate at lower voltage levels. The substitute parts identified maintain the same circuit topology, actuator configuration, and current handling capacity while offering higher voltage ratings and active product status.

Termination Compatibility: The AM50652C33-A uses 0.187" (4.7mm) quick-connect termination. One substitute part (831607B6.A) matches this termination exactly, while another (831607B3.A) uses 0.250" (6.3mm) termination, requiring connector adaptation.

Parameter Comparison

Engineering Selection Recommendations

831607B6.A (Crouzet) - Primary Substitute: This part is the preferred substitute for direct replacement applications. It maintains identical termination style (0.187" quick connect), matching the original connector interface without modification. The part is in active production status with RoHS compliance certification. The higher voltage rating (250V AC) provides operational margin above the original 125V specification. Operating temperature range (-40°C to 85°C) is narrower than the original but covers standard industrial environments. This configuration minimizes integration risk and connector rework.

831607B3.A (Crouzet) - Secondary Substitute: This part provides functional equivalence with identical electrical and mechanical specifications but requires connector adaptation due to the 0.250" (6.3mm) termination versus the original 0.187" (4.7mm). Selection of this part is appropriate when connector modification is acceptable or when the larger termination size offers mechanical advantages in the application. Active product status and RoHS compliance are maintained.

Temperature Consideration: Both Crouzet substitutes operate to 85°C maximum, compared to the original 105°C upper limit. Applications requiring operation above 85°C require thermal analysis to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 831607B6.A directly replace the Panasonic AM50652C33-A? A: Yes, for electrical and mechanical function. The 831607B6.A matches the circuit configuration (SPST-NC), current rating (6A AC), actuator type (lever, straight), mounting type (chassis mount), and termination style (0.187" quick connect). The higher voltage rating (250V AC versus 125V AC) is compatible with the original application. No connector modification is required.

Q: What is the difference between the two Crouzet substitutes? A: Both 831607B3.A and 831607B6.A are SPST-NC snap-action switches with identical electrical ratings and mechanical life. The primary difference is termination style: 831607B3.A uses 0.250" (6.3mm) quick connect, while 831607B6.A uses 0.187" (4.7mm) quick connect. The 831607B6.A matches the original termination and requires no connector rework.

Q: Are there temperature limitations with the substitute parts? A: The Crouzet substitutes are rated to -40°C to 85°C, compared to the original -25°C to 105°C. The lower upper temperature limit (85°C versus 105°C) should be evaluated for applications operating near or above 85°C. The extended lower temperature limit (-40°C versus -25°C) provides additional cold-temperature capability.

Q: Do the substitute parts meet regulatory requirements? A: Both Crouzet parts are RoHS compliant and REACH unaffected, meeting current environmental regulations. The original Panasonic part RoHS status is not specified. Both substitutes carry ECCN EAR99 classification, consistent with the original.

Q: What is the inventory status of these parts? A: The original AM50652C33-A is obsolete with 627 units in stock. The 831607B6.A has 1,095 units available, and the 831607B3.A has 724 units available, both in active production.

Q: Can I use the 831607B3.A if I modify the connector? A: Yes. The 831607B3.A is functionally equivalent and can be used with appropriate connector adaptation from 0.250" to 0.187" termination. This approach is valid when connector modification is feasible within the application design.
