AM51130C43-A Equivalent & Substitute Parts

Part Overview

The AM51130C43-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 0.187" termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance and repair applications where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51130C43-A is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Actuator type: Round pin plunger
• Mounting type: Chassis mount
• Termination style: Quick Connect - 0.187" (4.7mm)
• Operating position: 0.579" (14.7mm)

Electrical Performance Parameters:

• Current rating must meet or exceed 11A AC at the specified voltage
• Voltage rating must support minimum 125V AC operation
• Differential travel: 0.016" (0.4mm)

The Crouzet 83264841 satisfies these substitution criteria. It maintains identical circuit configuration, switch function, actuator geometry, mounting method, and termination compatibility. The substitute part exceeds the current rating requirement (12A AC vs. 11A AC) and provides higher voltage capability (250V AC vs. 125V AC), ensuring electrical performance compatibility in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264841 is the qualified substitute for the obsolete AM51130C43-A. Selection is based on the following factors:

Functional Equivalence: Both components share identical circuit topology (SPST-NO), switch operation (Off-Mom), actuator design (round pin plunger), and mechanical interface (chassis mount with 0.187" quick connect termination). Operating position and differential travel specifications are identical, ensuring mechanical compatibility in existing mounting configurations.

Electrical Compatibility: The Crouzet substitute exceeds the electrical requirements of the original component. With 12A AC capacity at 250V, it provides margin above the AM51130C43-A specification of 11A AC at 125V. This performance headroom ensures reliable operation in applications designed for the original part.

Product Status and Compliance: The Crouzet 83264841 is an active product with RoHS compliance certification, providing supply chain continuity and regulatory alignment for new designs or production restarts. Both components maintain REACH Unaffected status.

Temperature Operating Range: The substitute part extends the upper temperature limit to 125°C compared to the original 105°C maximum, providing enhanced thermal margin in temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264841 be used as a direct replacement for the AM51130C43-A?

A: Yes. Both components share identical SPST-NO circuit configuration, Off-Mom switch function, round pin plunger actuator, chassis mount installation, and 0.187" quick connect termination. Operating position and differential travel specifications are identical, confirming mechanical and electrical compatibility.

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

A: The primary differences are manufacturer origin and product status. The Crouzet 83264841 is an active product with RoHS compliance, while the Panasonic AM51130C43-A is obsolete. The Crouzet part provides higher current capacity (12A vs. 11A AC) and voltage rating (250V vs. 125V AC), plus an extended upper operating temperature of 125°C versus 105°C.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both switches feature identical operating position (0.579" / 14.7mm), differential travel (0.016" / 0.4mm), and quick connect termination geometry (0.187" / 4.7mm). Chassis mount installation is identical, confirming direct mechanical compatibility.

Q: Does the higher voltage rating of the Crouzet part affect compatibility?

A: No. Higher voltage rating indicates greater electrical capability and does not create compatibility issues. The substitute part operates safely in circuits designed for 125V AC operation.

Q: What is the impact of the RoHS compliance difference?

A: The Crouzet 83264841 carries RoHS compliance certification, making it suitable for applications subject to RoHS regulatory requirements. The original Panasonic part does not specify RoHS status. Both maintain REACH Unaffected designation.

Q: Are there any operating force or release force differences to consider?

A: Operating force differs between the two components (100gf for Panasonic vs. 51gf for Crouzet). This represents a mechanical characteristic difference but does not affect functional substitution, as both maintain the same switch function and actuator type. Application-specific force requirements should be evaluated independently.
