AM51116D43N-A Equivalent & Substitute Parts

Part Overview

The AM51116D43N-A is a snap action switch manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) device with on-momentary function. This chassis-mounted switch is rated for 11A AC at 125V and 600mA DC at 125V, featuring a lever roller actuator with quick connect termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM51116D43N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must be On-Momentary to preserve operational behavior
• Actuator Type: Must include lever and roller configuration for mechanical compatibility
• Mounting Type: Must be chassis mount to fit existing mechanical interfaces
• Termination Style: Must be quick connect 0.250" (6.3mm) for direct connection compatibility
• Current and Voltage Ratings: Substitute must meet or exceed the 11A AC @ 125V requirement
• Mechanical Interface: Operating position, pretravel, and overtravel dimensions must be compatible with existing mechanical linkages

The Crouzet 83264027 satisfies these core substitution criteria through matching circuit configuration, switch function, actuator type, mounting method, and termination style. The substitute provides higher voltage rating (250V AC) and comparable current capacity (12A AC), ensuring compatibility in the original application context.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264027 is a direct functional substitute for the obsolete AM51116D43N-A. Both switches share identical circuit topology (SPDT), switch function (On-Momentary), actuator configuration (lever roller), mounting method (chassis mount), and termination interface (quick connect 0.250").

The Crouzet substitute provides enhanced electrical ratings (12A AC at 250V versus 11A AC at 125V), ensuring operation within the original application's electrical envelope with margin. Operating position dimensions are within 0.009" (0.2mm) of the original, maintaining mechanical compatibility with existing linkage systems.

The Crouzet 83264027 holds active product status with RoHS compliance certification, supporting long-term supply continuity and regulatory alignment. The substitute's extended upper operating temperature limit (125°C versus 105°C) provides additional thermal margin in applications approaching the original device's temperature boundary.

Mechanical life specification differs between devices (1,000,000 cycles for Crouzet versus 10,000,000 cycles for Panasonic). Application duty cycle analysis is required to determine if this difference impacts system reliability in the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264027 directly replace the AM51116D43N-A without modification?

A: Yes. Both switches share identical circuit configuration (SPDT), switch function (On-Momentary), actuator type (lever roller), chassis mount interface, and quick connect 0.250" termination. Operating position dimensions are within 0.009" (0.2mm), ensuring mechanical compatibility with existing mechanical linkages and panel cutouts.

Q: What are the key electrical differences between these switches?

A: The Crouzet substitute is rated for 12A AC at 250V, compared to the original 11A AC at 125V. The higher voltage rating ensures the substitute operates safely in the original application. Both switches maintain identical 10gf release force specification.

Q: Are there mechanical compatibility concerns?

A: Operating position, pretravel, and overtravel dimensions are comparable between devices. The Crouzet operating force is 51gf versus the original 60gf, representing a 15% reduction. Applications with tight actuator force budgets should verify this difference does not impact system performance.

Q: What is the impact of the different mechanical life ratings?

A: The AM51116D43N-A specifies 10,000,000 mechanical cycles versus 1,000,000 cycles for the Crouzet 83264027. Application duty cycle analysis is necessary to determine if this tenfold difference affects system reliability. High-cycle applications may require additional evaluation.

Q: Does the Crouzet substitute meet current regulatory requirements?

A: The Crouzet 83264027 is RoHS compliant and holds active product status, supporting regulatory alignment and long-term supply availability. The original Panasonic device is obsolete, making the active Crouzet substitute the preferred choice for new designs and long-term system support.

Q: Are there temperature range considerations?

A: The Crouzet substitute operates from -20°C to 125°C, compared to the original -25°C to 105°C range. The substitute provides 20°C additional upper temperature margin but has a 5°C reduction at the lower boundary. Applications operating below -20°C require verification against system requirements.
