AM51114D43N-A Equivalent & Substitute Parts

Part Overview

The AM51114D43N-A is a snap action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This component operates at 11A AC / 600mA DC at 125V with a lever-actuated simulated roller mechanism. The part is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and new design implementations where this switch function is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51114D43N-A is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Actuator type must be Lever with Simulated Roller
• Mounting type must be Chassis Mount
• Termination style must be Quick Connect format
• Current and voltage ratings must meet or exceed application requirements
• Operating temperature range must encompass the application environment

The two substitute parts identified meet these core functional and mechanical criteria, though with variations in electrical ratings and performance characteristics that must be evaluated against specific application demands.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264026 is an active product with higher AC current capacity (12A) and voltage rating (250V), providing margin above the original specification. This part maintains identical termination geometry and actuator characteristics. The Crouzet part is RoHS Compliant, supporting modern supply chain requirements.

The Honeywell V7-1X1AD8-304 is an active product with extended operating temperature range (-40°C to 177°C) and equivalent electrical life rating. This part features RoHS Compliance and maintains mechanical life equivalent to the original. The termination connector size differs (0.187" vs 0.250"), requiring mechanical interface verification. The AC current rating (6A) is lower than the original specification and must be evaluated against application load requirements.

Both substitutes are active products with current manufacturing support and compliance certifications, addressing the obsolescence of the original AM51114D43N-A.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264026 directly replace the AM51114D43N-A?

A: The Crouzet 83264026 meets all core functional requirements: SPDT circuit, On-Momentary function, lever simulated roller actuator, chassis mount configuration, and 0.250" quick connect termination. The higher current (12A) and voltage (250V) ratings provide operational margin. Mechanical life differs (1,000,000 vs 10,000,000 cycles), which must be evaluated against application duty cycle expectations.

Q: What is the primary limitation of the Honeywell V7-1X1AD8-304 as a substitute?

A: The Honeywell part features a 0.187" quick connect termination versus the original 0.250" specification, requiring mechanical interface modification. Additionally, the AC current rating (6A) is lower than the original (11A), limiting applicability to lower-load applications.

Q: Are both substitute parts suitable for high-temperature applications?

A: The Honeywell V7-1X1AD8-304 supports extended temperature operation (-40°C to 177°C), exceeding the original range. The Crouzet 83264026 operates to 125°C, slightly above the original maximum of 105°C. Application temperature requirements determine suitability.

Q: What compliance certifications apply to the substitute parts?

A: The Crouzet 83264026 is RoHS Compliant and REACH Unaffected. The Honeywell V7-1X1AD8-304 is RoHS Compliant. Both parts carry EAR99 ECCN classification, matching the original component.

Q: How do mechanical life ratings compare?

A: The original AM51114D43N-A and Honeywell V7-1X1AD8-304 both specify 10,000,000 mechanical cycles. The Crouzet 83264026 specifies 1,000,000 cycles, representing a tenfold reduction. Application cycle frequency must be evaluated against this specification.
