AM51135D43N-A Equivalent & Substitute Parts

Part Overview

The AM51135D43N-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 AM51135D43N-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 Compatibility Criteria:

• Operating position tolerance must accommodate 0.815" (20.7mm) nominal travel
• Pretravel and differential travel characteristics must be compatible with existing mechanical linkages

The Crouzet 83264827 satisfies all primary compatibility criteria and exceeds electrical performance specifications with 12A AC at 250V rating, making it a valid functional substitute despite differences in operating force and mechanical life specifications.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264827 is a functionally equivalent substitute for the AM51135D43N-A based on matching circuit topology, switch function, actuator design, mounting configuration, and termination interface. The substitute part exceeds the original specification in AC current capacity (12A vs. 11A) and AC voltage rating (250V vs. 125V), providing improved electrical margin.

The Crouzet part is currently in active production status, ensuring long-term availability compared to the obsolete Panasonic original. The substitute carries RoHS compliance certification, meeting modern regulatory requirements for electronic component procurement.

Mechanical life specification differs significantly (1,000,000 cycles vs. 10,000,000 cycles). Applications requiring extended mechanical cycling beyond 1,000,000 operations should evaluate this parameter against actual duty cycle requirements. Operating force is lower on the substitute (51gf vs. 110gf), which may affect tactile feedback and actuation characteristics in manual control applications.

Operating temperature range on the substitute extends to 125°C maximum, exceeding the original -25°C to 105°C specification. The operating position differential (0.806" vs. 0.815") is negligible for mechanical linkage compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264827 directly replace the AM51135D43N-A in existing assemblies?

A: Yes, provided the application does not exceed 1,000,000 mechanical cycles. The substitute matches all critical interface parameters: SPST-NO circuit, Off-Mom function, lever-roller actuator, chassis mount, and 0.250" quick connect termination. Physical mounting dimensions and electrical performance are compatible.

Q: What is the significance of the lower operating force on the Crouzet part?

A: The Crouzet 83264827 requires 51gf actuation force compared to 110gf on the original. This lower force may alter tactile feedback in manual applications and could affect performance in systems with mechanical linkages designed for the higher force specification. Mechanical linkage analysis is recommended for critical applications.

Q: Does the Crouzet part meet current regulatory requirements?

A: Yes. The Crouzet 83264827 carries RoHS compliance certification and REACH unaffected status, meeting current electronic component procurement standards. The original Panasonic part is obsolete and does not carry these certifications.

Q: Are there DC voltage limitations on the Crouzet substitute?

A: The Crouzet 83264827 specification does not include DC voltage rating data. The original part is rated 600mA DC at 125V. Applications requiring DC operation should contact the manufacturer for DC performance confirmation before implementation.

Q: How do the mechanical life specifications affect component selection?

A: The original Panasonic part is rated for 10,000,000 mechanical cycles, while the Crouzet substitute is rated for 1,000,000 cycles. Applications with duty cycles exceeding 1,000,000 operations should evaluate whether the substitute meets service life requirements. Standard industrial applications typically operate within the 1,000,000 cycle range.

Q: Is the operating position difference significant for mechanical compatibility?

A: The operating position difference is 0.009" (0.2mm), representing less than 1% variance from the original specification. This difference is negligible for standard mechanical linkage applications and does not affect compatibility.
