AM51130D43N-A Equivalent & Substitute Parts

Part Overview

The AM51130D43N-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 round pin plunger actuator and quick connect 0.250" (6.3mm) termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51130D43N-A is determined by the following critical parameters:

Circuit configuration must remain SPST-NO with Off-Mom (momentary) function to maintain identical electrical behavior in the application.

Actuator type must be Round (Pin Plunger) to ensure mechanical compatibility with existing mounting interfaces.

Mounting type must be Chassis Mount to preserve installation geometry.

Termination style must be Quick Connect - 0.250" (6.3mm) to ensure direct connection compatibility without adapter requirements.

Current and voltage ratings must meet or exceed the application requirements: minimum 11A AC at 125V AC, or equivalent DC ratings.

Operating position of 0.579" (14.7mm) establishes the stroke length requirement for functional equivalence.

The Crouzet 83264821 qualifies as a substitute part based on these criteria: it maintains SPST-NO circuit configuration with Off-Mom function, features an identical round pin plunger actuator, chassis mount installation, and matching 0.250" (6.3mm) quick connect termination. Its 12A AC rating at 250V AC exceeds the AM51130D43N-A requirements, and its 0.579" (14.7mm) operating position matches the original specification.

Engineering Selection Recommendations

The Crouzet 83264821 is the qualified substitute for the obsolete AM51130D43N-A. Selection is based on the following engineering criteria:

The Crouzet part maintains identical circuit topology (SPST-NO) and switch function (Off-Mom), ensuring direct functional replacement without application logic modification.

Mechanical compatibility is preserved through matching actuator type (round pin plunger), mounting method (chassis mount), and termination interface (0.250" quick connect).

Electrical performance exceeds original specifications: 12A AC at 250V AC provides margin above the 11A at 125V AC requirement, accommodating potential application variations or future upgrades.

The Crouzet 83264821 holds Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Panasonic part.

The Crouzet part is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards applicable to electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264821 directly replace the AM51130D43N-A without modification?

A: Yes. Both parts share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (round pin plunger), mounting type (chassis mount), and termination style (0.250" quick connect). No mechanical or electrical adaptation is required.

Q: What is the significance of the higher voltage rating on the Crouzet part?

A: The Crouzet 83264821 is rated for 250V AC compared to the AM51130D43N-A at 125V AC. This higher rating provides design margin and allows the substitute to function in applications requiring higher voltage operation. The part will operate correctly at the original 125V AC specification.

Q: Are there differences in operating force between these parts?

A: Yes. The AM51130D43N-A requires 100gf operating force, while the Crouzet 83264821 requires 51gf. The lower operating force on the Crouzet part may result in easier actuation. Verify that the application mechanism can accommodate this difference if manual actuation force is a critical design parameter.

Q: What is the difference in mechanical life ratings?

A: The AM51130D43N-A specifies 10,000,000 cycles mechanical life, while the Crouzet 83264821 specifies 1,000,000 cycles. For applications requiring extended mechanical cycling, the original Panasonic specification provides higher durability. Evaluate application duty cycle requirements against the Crouzet rating.

Q: Are both parts cadmium-free?

A: The AM51130D43N-A is explicitly cadmium-free. The Crouzet 83264821 specification does not list cadmium content. Verify cadmium-free status with the Crouzet manufacturer if this is a regulatory or environmental requirement for your application.

Q: What is the operating temperature range difference?

A: The AM51130D43N-A operates from -25°C to 105°C, while the Crouzet 83264821 operates from -20°C to 125°C. The Crouzet part has a narrower low-temperature range (-20°C vs. -25°C) but extends the high-temperature limit to 125°C. Confirm the application temperature environment against both specifications.
