AM50626C33-A Equivalent & Substitute Parts
Part Overview
The AM50626C33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as SPST-NC (Single Pole Single Throw - Normally Closed) with chassis mount termination. This component is rated for 6A AC at 125V and 500mA DC at 125V, featuring a lever roller actuator with quick connect 0.187" (4.7mm) termination. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing maintenance and new designs requiring this switch topology.

Substitute Part Grouping Explanation
Substitution of the AM50626C33-A is determined by strict equivalence across the following parameters:
Critical Matching Parameters:
- Circuit configuration: SPST-NC topology
- Switch function: On-Momentary operation
- Actuator type: Lever with roller mechanism
- Mounting type: Chassis mount
- Termination style: Quick connect 0.187" (4.7mm)
Electrical Compatibility Parameters:
- Current rating must meet or exceed 6A AC and 500mA DC
- Voltage rating must support minimum 125V AC and 125V DC operation
- Operating temperature range must encompass -25°C to 105°C
The TFCFK6SA1040W from C&K satisfies all critical matching parameters and exceeds electrical requirements with 11A AC at 277V and 500mA DC at 125V ratings, while maintaining identical actuator and termination specifications.

Engineering Selection Recommendations
The TFCFK6SA1040W is a direct functional substitute for the AM50626C33-A based on matching circuit topology, actuator configuration, and termination specifications. The substitute component exceeds the original part's electrical ratings, providing 11A AC capacity versus 6A AC, and supports higher AC voltage operation at 277V.
The TFCFK6SA1040W maintains active product status with ROHS3 compliance, ensuring continued availability and regulatory alignment. The operating temperature range of -40°C to 85°C encompasses the critical lower bound of the original specification (-25°C), though the upper limit is reduced to 85°C from 105°C. Applications requiring operation above 85°C require evaluation against specific thermal requirements.
Both components share identical moisture sensitivity classification (MSL 1) and ECCN coding (EAR99), supporting equivalent supply chain and export compliance handling.
Frequently Asked Questions (FAQ)
Q: Can the TFCFK6SA1040W directly replace the AM50626C33-A in existing designs?
A: Yes, for applications operating within -40°C to 85°C and requiring 6A AC at 125V or lower. The substitute matches all mechanical and electrical interface specifications. Applications requiring operation above 85°C require thermal evaluation.
Q: What are the key differences between these components?
A: The TFCFK6SA1040W provides higher current capacity (11A AC versus 6A AC) and supports higher AC voltage (277V versus 125V). Operating force is higher at 65gf versus 30gf. The substitute has a narrower upper temperature limit (85°C versus 105°C) and lower pretravel distance (0.060" versus 0.125").
Q: Are there packaging differences?
A: The AM50626C33-A is supplied in standard packaging, while the TFCFK6SA1040W is supplied in bulk packaging. Both use identical quick connect 0.187" (4.7mm) termination, requiring no connector modifications.
Q: What compliance certifications apply to the substitute?
A: The TFCFK6SA1040W is ROHS3 compliant and REACH affected. The original AM50626C33-A is REACH unaffected. Both components carry EAR99 ECCN classification and HTSUS code 8536.50.7000.
Q: Is the substitute suitable for DC applications?
A: Both components are rated for 500mA DC at 125V. The substitute is suitable for DC applications within this specification.
