AM51650C73N-A Equivalent & Substitute Parts

Part Overview

The AM51650C73N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NC (Single Pole Single Throw - Normally Closed) chassis mount component. This switch is rated for 16A AC at 125V and features a round pin plunger actuator with quick connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51650C73N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NC to maintain electrical function
• Switch Function: Must be On-Momentary operation
• Current Rating: Minimum 16A AC capability required
• Actuator Type: Round pin plunger for mechanical compatibility
• Mounting Type: Chassis mount configuration
• Termination Style: Quick connect 0.187" (4.7mm) terminals
• Operating Position: 0.579" (14.7mm) stroke length

The MAH6A from APEM Inc. meets these core substitution criteria. While voltage rating differs (250V vs. 125V), the higher voltage rating provides operational compatibility in 125V circuits. Operating force and temperature range variations are within acceptable engineering tolerances for equivalent snap-action switch applications.

Parameter Comparison

Engineering Selection Recommendations

The MAH6A represents a direct functional equivalent for AM51650C73N-A replacement applications. Both switches share identical circuit configuration, current rating, actuator geometry, mounting interface, and mechanical life specifications. The MAH6A is currently in active production status, ensuring availability and supply chain continuity.

The MAH6A's 250V AC rating exceeds the original 125V specification, providing enhanced voltage margin in equivalent circuits. The 57gf reduction in operating force (343gf vs. 400gf) falls within normal manufacturing tolerances for snap-action switches and does not compromise functional performance in standard applications.

The MAH6A carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both components share identical ECCN and HTSUS classifications, confirming trade compliance equivalency.

Frequently Asked Questions (FAQ)

Q: Can the MAH6A directly replace the AM51650C73N-A in existing assemblies?

A: Yes. Both switches share identical SPST-NC circuit configuration, 16A AC current rating, round pin plunger actuator, chassis mount interface, and 0.187" quick connect termination. Operating position and mechanical life specifications are identical. Physical and electrical substitution is direct.

Q: Does the higher voltage rating (250V vs. 125V) affect compatibility?

A: No. A component rated for higher voltage operates safely at lower voltages. The MAH6A's 250V rating provides additional voltage margin and does not create compatibility issues in 125V circuits.

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

A: The MAH6A operates at 343gf compared to the original 400gf. This 57gf difference represents approximately 14% reduction and is within normal manufacturing variation for snap-action switches. Functional performance in standard applications remains equivalent.

Q: Why is product status important for substitution?

A: The AM51650C73N-A is obsolete, meaning Panasonic Electric Works no longer manufactures or supports this component. The MAH6A is in active production, ensuring long-term availability, technical support, and supply chain reliability for ongoing applications.

Q: Are there compliance differences between these parts?

A: The MAH6A carries ROHS3 compliance certification. Both components share identical ECCN (EAR99) and HTSUS (8536.50.9040) classifications, confirming regulatory and trade compliance equivalency.
