Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50642D33-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT (Single Pole Double Throw)
• Switch Function: Must be On-Mom (On-Momentary)
• Voltage Rating: Must support 125V AC and 125V DC minimum
• Actuator Type: Must be Lever, Straight configuration
• Mounting Type: Must be Chassis Mount
• Termination Style: Quick Connect format (connector size variations acceptable within mechanical compatibility)
• Operating Temperature Range: Must encompass or exceed -25°C to 105°C
• Electrical Life: Must meet or exceed 100,000 cycles
• Mechanical Life: Must meet or exceed 10,000,000 cycles

The substitute parts V7-1B17D8-122 and V7-1B17D8-122-1 from Honeywell Sensing and Productivity Solutions meet these core functional and electrical requirements, though with variations in current rating capacity and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

V7-1B17D8-122 is the primary substitute for AM50642D33-A. This part is currently in active production status with full technical specifications provided. It maintains functional equivalence across all critical parameters: SPDT circuit configuration, On-Mom switch function, 125V AC/DC voltage ratings, straight lever actuator, and chassis mount design. The Honeywell part exceeds the original specification with 11A AC current capacity versus 6A, providing enhanced current handling capability. Both parts share identical electrical life (100,000 cycles) and mechanical life (10,000,000 cycles) ratings. The Honeywell substitute carries RoHS Compliance certification, meeting modern regulatory requirements. Operating temperature range differs slightly (-40°C to 85°C versus -25°C to 105°C); applications requiring the full original temperature envelope should be evaluated for compatibility.

V7-1B17D8-122-1 is listed as an alternative substitute but lacks complete technical specifications in the provided data. This part is confirmed as active production status and RoHS Compliant. Selection of this variant should be contingent upon obtaining complete electrical and mechanical specifications from the manufacturer to verify full parameter alignment with application requirements.

Frequently Asked Questions (FAQ)

Q: Can V7-1B17D8-122 directly replace AM50642D33-A in existing designs?

A: V7-1B17D8-122 is functionally equivalent for SPDT On-Mom switching applications at 125V. The primary consideration is termination connector size: the original uses 0.250" (6.3mm) quick connect terminals while the substitute uses 0.187" (4.7mm). Mechanical compatibility with existing harnesses and PCB layouts must be verified. Current capacity is higher on the substitute (11A AC versus 6A AC), which is not a limitation. Operating temperature range differs; verify if your application requires the full -25°C to 105°C envelope of the original.

Q: What are the key differences between V7-1B17D8-122 and V7-1B17D8-122-1?

A: V7-1B17D8-122-1 has incomplete technical documentation in available data. Both are Honeywell products in active production with RoHS Compliance and MSL 1 rating. Complete specifications for V7-1B17D8-122-1 must be obtained from the manufacturer before confirming substitution suitability.

Q: Are there any compliance or regulatory differences?

A: The Honeywell substitutes (V7-1B17D8-122 and V7-1B17D8-122-1) are RoHS Compliant, while the original Panasonic part does not specify RoHS status. Both substitute parts maintain REACH Unaffected status. For applications subject to RoHS requirements, the Honeywell alternatives provide compliance assurance.

Q: How do mechanical specifications compare?

A: Both the original and V7-1B17D8-122 share identical operating position (0.602" / 15.3mm) and electrical/mechanical life ratings. Pretravel, differential travel, and overtravel specifications differ between the parts. Operating force is higher on the substitute (43gf versus 30gf). These mechanical differences may affect actuation feel and force requirements in the application.

Q: What should be verified before implementing a substitute?

A: Verify connector compatibility with existing harnesses and PCB layouts due to termination size differences. Confirm operating temperature range adequacy for your application environment. Validate that the higher operating force (43gf versus 30gf) is acceptable for your actuation mechanism. Test electrical performance under actual load conditions if the application is critical.
