AM51145C43N-A Equivalent & Substitute Parts

Part Overview

The AM51145C43N-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 component is rated for 11A AC at 125V and features a lever-roller actuator with chassis mount termination. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM51145C43N-A are selected based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: SPDT topology required for identical switching behavior
• Switch Function: On-momentary operation maintained across all substitutes
• Actuator Type: Lever-roller mechanism for mechanical compatibility
• Mounting Type: Chassis mount configuration for installation compatibility
• Termination Style: Quick Connect 0.187" (4.7mm) for electrical connection compatibility
• Voltage and Current Ratings: Minimum AC voltage of 125V and current capacity of 11A to support existing circuit requirements

The two substitute parts identified meet these core criteria while offering enhanced or equivalent electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83264047: This substitute provides active product status with higher voltage rating (250V AC) and equivalent current capacity (12A AC). The component is RoHS compliant and REACH unaffected, meeting modern regulatory requirements. Operating force is reduced to 51gf compared to the original 110gf, which may affect tactile feedback in applications requiring higher actuation force. Mechanical life is rated at 1,000,000 cycles, significantly lower than the original specification.

Honeywell V15T16-EZ100A05: This substitute offers the highest current rating (16A AC) and voltage rating (250V AC) among available options, providing design margin for circuit protection. Operating force (120gf) closely matches the original specification. RoHS compliance and active product status ensure long-term availability. Mechanical life is rated at 5,000,000 cycles, providing intermediate durability between the original and Crouzet alternatives. Operating temperature range extends to 125°C, exceeding the original specification.

Both substitutes maintain identical circuit topology, switch function, actuator type, mounting configuration, and termination style. Selection between alternatives depends on specific application requirements regarding mechanical life, operating force sensitivity, and voltage/current margin requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264047 directly replace the AM51145C43N-A in all applications?

A: The Crouzet 83264047 maintains functional equivalence in circuit topology, switch function, actuator type, mounting, and termination. However, the reduced operating force (51gf vs. 110gf) and significantly lower mechanical life (1,000,000 vs. 10,000,000 cycles) may impact applications requiring high actuation force or extended cycle life. Voltage and current ratings are higher, providing design margin for most 125V circuits.

Q: What are the key differences between the two substitute options?

A: The Honeywell V15T16-EZ100A05 provides higher current capacity (16A vs. 12A), superior mechanical life (5,000,000 vs. 1,000,000 cycles), and operating force closer to the original specification (120gf vs. 51gf). The Crouzet 83264047 offers lower operating force, which may be advantageous in applications requiring minimal actuation effort. Both maintain identical mechanical and electrical interfaces.

Q: Are the substitute parts physically compatible with existing mounting locations?

A: All three components feature identical mounting type (chassis mount) and termination style (Quick Connect 0.187"). Operating position measurements are nearly identical (0.815" original vs. 0.806" Crouzet and 0.812" Honeywell), confirming mechanical compatibility within standard tolerance ranges.

Q: Do the substitute parts meet current regulatory compliance standards?

A: The Honeywell V15T16-EZ100A05 and Crouzet 83264047 are both active products with RoHS compliance certification. The original AM51145C43N-A is obsolete and lacks modern compliance documentation. Both substitutes are suitable for applications requiring current regulatory adherence.

Q: How do the electrical life ratings compare?

A: The original AM51145C43N-A specifies 100,000 electrical cycles. The Honeywell substitute provides 50,000 cycles, while the Crouzet specification does not include electrical life data. For applications with high electrical switching frequency, the Honeywell option provides documented performance characteristics.
