AM51145D43N-A Equivalent & Substitute Parts

Part Overview

The AM51145D43N-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 equivalent and substitute parts essential for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51145D43N-A is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must support on-momentary operation
• Actuator Type: Must include lever and roller configuration for mechanical compatibility
• Mounting Type: Must be chassis mount to ensure physical fit
• Termination Style: Must use quick connect 0.250" (6.3mm) terminals for direct connection compatibility
• Current and Voltage Ratings: Substitute must meet or exceed 11A AC at 125V minimum requirements
• Operating Temperature Range: Must encompass or exceed -25°C to 105°C specification

Two substitute parts meet these criteria:

Crouzet 83264027: Meets all core functional requirements with enhanced voltage rating (250V AC) and comparable current capacity (12A AC). Operating position and differential travel remain within acceptable mechanical tolerances.

Honeywell V3L-2163: Meets all core functional requirements with identical current rating (11A) and matching termination style. Classified as active product status with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

Crouzet 83264027 is suitable for direct substitution in applications where the enhanced voltage rating (250V AC versus 125V AC) provides additional design margin. The active product status ensures continued availability. Mechanical life specification of 1,000,000 cycles is lower than the original part; applications requiring extended cycle life should evaluate this parameter against actual duty cycle requirements.

Honeywell V3L-2163 is suitable for substitution in applications where RoHS compliance is mandated or preferred. The active product status and RoHS certification provide long-term supply assurance. The solder termination style requires circuit board modification compared to the quick connect termination of the original part. This substitution is appropriate for new designs or redesigns where termination style change is acceptable.

Both substitute parts maintain SPDT circuit configuration and on-momentary function. Selection between substitutes depends on termination style requirements (quick connect versus solder) and compliance certifications needed for the application.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264027 be used as a direct replacement for the AM51145D43N-A?

A: Yes, the Crouzet 83264027 maintains identical circuit configuration (SPDT), switch function (on-momentary), actuator type (lever roller), mounting type (chassis mount), and termination style (quick connect 0.250"). The higher voltage rating (250V AC) and current capacity (12A AC) provide additional design margin. Mechanical life is lower (1,000,000 versus 10,000,000 cycles); verify this meets application requirements.

Q: What is the primary difference between the two substitute parts?

A: The Crouzet 83264027 uses quick connect termination identical to the original part, while the Honeywell V3L-2163 uses solder termination. The Honeywell part carries RoHS compliance certification. The Crouzet part supports higher voltage (250V AC) and current (12A AC) ratings.

Q: Does the Honeywell V3L-2163 require circuit board modifications?

A: Yes. The Honeywell V3L-2163 uses solder termination instead of quick connect 0.250" terminals. This requires circuit board redesign to accommodate solder pads in place of quick connect receptacles. This substitution is appropriate for new designs or complete redesigns where termination style change is acceptable.

Q: Are both substitute parts currently available?

A: Yes. Both the Crouzet 83264027 and Honeywell V3L-2163 are classified as active products, ensuring continued supply and availability compared to the obsolete AM51145D43N-A.

Q: Which substitute part should be selected for new designs?

A: Selection depends on specific application requirements. For applications requiring quick connect termination without circuit modification, select Crouzet 83264027. For applications where RoHS compliance is required or preferred, select Honeywell V3L-2163. Both parts meet the core electrical and mechanical requirements of the original part.
