AM51165D43N-A Equivalent & Substitute Parts

Part Overview

The AM51165D43N-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 lever roller actuator with quick connect termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM51165D43N-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Actuator type must include lever and roller design
• Mounting type must be chassis mount
• Termination style must be quick connect 0.250" (6.3mm)

Electrical Performance Criteria:

• AC current rating must meet or exceed 11A
• AC voltage rating must meet or exceed 125V
• DC voltage rating must meet or exceed 125V

Mechanical Criteria:

• Operating position tolerance must be compatible with 0.815" (20.7mm) specification
• Mechanical life must support industrial duty cycle requirements

The Crouzet 83264827 qualifies as a substitute part because it maintains identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator design (lever, roller), mounting method (chassis mount), and termination style (quick connect 0.250"). The Crouzet part exceeds electrical requirements with 12A AC at 250V rating and demonstrates superior operating characteristics with lower operating force (51gf vs. 110gf) and comparable operating position (0.806" vs. 0.815").

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264827 is a qualified substitute for the AM51165D43N-A based on functional equivalence and electrical performance superiority. The substitute part maintains all critical mechanical and electrical interface requirements while offering active product status and extended availability.

The Crouzet part demonstrates higher AC voltage rating (250V vs. 125V) and equivalent or superior current handling (12A vs. 11A), providing margin for system reliability. Operating temperature range extends to 125°C compared to 105°C maximum for the original part.

Mechanical life specification differs significantly (1,000,000 cycles vs. 10,000,000 cycles). This parameter should be evaluated against actual application duty cycle requirements. The lower operating force (51gf vs. 110gf) and release force (10gf vs. 20gf) of the Crouzet part may influence actuator feel and system response characteristics.

Both parts carry identical moisture sensitivity level (MSL 1 - Unlimited) and ECCN classification (EAR99). The Crouzet part includes RoHS compliance and REACH unaffected status, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264827 directly replace the AM51165D43N-A in existing assemblies?

A: Yes, for applications operating at or below 125V AC and 11A AC. The Crouzet part maintains identical mounting, termination, and circuit configuration. Physical dimensions are compatible (operating position 0.806" vs. 0.815"). Verify that the lower operating force (51gf vs. 110gf) is acceptable for your actuator mechanism.

Q: What is the significance of the mechanical life difference?

A: The AM51165D43N-A specifies 10,000,000 mechanical cycles while the Crouzet 83264827 specifies 1,000,000 cycles. Select based on application duty cycle. High-frequency switching applications may require the original specification or alternative parts with higher cycle ratings.

Q: Are there compliance or certification differences between these parts?

A: The Crouzet 83264827 is RoHS compliant and REACH unaffected. The AM51165D43N-A specification does not include these certifications. Both parts carry identical MSL 1 and EAR99 classifications. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: How do the operating force specifications affect substitution?

A: Operating force (110gf original vs. 51gf substitute) determines the physical effort required to actuate the switch. The Crouzet part requires approximately 46% less force. This may affect system ergonomics, mechanical linkage design, or automated actuation requirements. Evaluate against your specific application mechanics.

Q: Is the extended temperature range of the Crouzet part beneficial?

A: The Crouzet 83264827 operates to 125°C maximum compared to 105°C for the original part, providing 20°C additional margin. This is beneficial for applications in elevated ambient or component self-heating environments. The lower temperature limit (-20°C vs. -25°C) is less restrictive for most industrial applications.
