AM51162D43N-A Equivalent & Substitute Parts

Part Overview

The AM51162D43N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device with chassis mount installation. This switch is rated for 11A AC at 125V and 600mA DC at 125V, featuring a straight lever actuator and quick connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51162D43N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO to maintain identical electrical topology
• Switch Function: Must be Off-Mom (momentary) to preserve operational behavior
• Mounting Type: Must be Chassis Mount for mechanical compatibility
• 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
• Actuator Type: Must be Lever, Straight to ensure identical user interface and mechanical envelope

The Crouzet 83264822 satisfies all mandatory substitution criteria. While it operates at higher voltage (250V AC) and current (12A AC) ratings, these represent enhanced electrical capability rather than incompatibility. The mechanical parameters—operating position (0.606" vs. 0.602"), pretravel, differential travel, and overtravel—remain within acceptable tolerance ranges for functional equivalence in chassis-mounted applications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264822 is a functionally equivalent substitute for the obsolete AM51162D43N-A based on matching circuit topology (SPST-NO), switch function (Off-Mom), mounting configuration (Chassis Mount), and termination interface (Quick Connect - 0.250"). Both devices employ identical actuator geometry (Lever, Straight) and maintain compatible mechanical travel characteristics.

The Crouzet substitute provides enhanced electrical ratings (12A AC @ 250V versus 11A AC @ 125V), ensuring compatibility with the original application's power requirements. The Crouzet device is currently in active production status with RoHS compliance certification, supporting long-term supply chain continuity and regulatory alignment.

Mechanical life specification differs between the two devices (1,000,000 cycles for Crouzet versus 10,000,000 cycles for Panasonic). Applications requiring extended cycle life beyond 1,000,000 operations should evaluate this parameter against specific duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264822 directly replace the AM51162D43N-A in existing assemblies?

A: Yes. Both switches share identical circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Chassis Mount), and termination style (Quick Connect - 0.250"). Mechanical envelope compatibility is confirmed through operating position and travel specifications. No circuit redesign or mechanical modification is required.

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

A: The primary differences are electrical ratings and mechanical life. The Crouzet operates at 250V AC (versus 125V AC) and 12A (versus 11A), providing higher electrical capacity. Mechanical life is specified at 1,000,000 cycles for Crouzet compared to 10,000,000 cycles for Panasonic. Operating force is slightly lower on the Crouzet (51gf versus 60gf).

Q: Is the Crouzet 83264822 RoHS compliant?

A: Yes. The Crouzet 83264822 is RoHS Compliant and REACH Unaffected, supporting applications with regulatory compliance requirements.

Q: Are there any temperature range limitations when substituting?

A: The Crouzet operates across -20°C to 125°C, compared to the Panasonic range of -25°C to 105°C. For applications requiring operation below -20°C, the Crouzet substitute may not be suitable. For applications within -20°C to 105°C, both devices are compatible.

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

A: The Panasonic AM51162D43N-A is rated for 10,000,000 mechanical cycles, while the Crouzet 83264822 is rated for 1,000,000 cycles. For applications with duty cycles exceeding 1,000,000 operations, the Crouzet substitute may reach end-of-life sooner. Evaluate actual application cycle requirements before selection.

Q: Can I use the Crouzet in a 125V AC circuit?

A: Yes. The Crouzet 83264822 is rated for 250V AC, which exceeds the 125V AC requirement of the original application. Operating at lower voltage than the device rating does not create compatibility issues.
