AM50064D43-A Equivalent & Substitute Parts

Part Overview

The AM50064D43-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works. This chassis-mount switch is rated for 100mA at 125V AC and 30V DC, featuring a lever with simulated roller actuator and quick connect termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50064D43-A requires matching the following critical parameters:

Circuit & Function Compatibility:

• SPST-NO configuration (single pole, single throw, normally open contact)
• Off-Momentary switch function

Electrical Ratings:

• Current capacity must meet or exceed 100mA
• Voltage ratings must support the application's AC and DC requirements
• The substitute must be rated for at least 125V AC operation

Mechanical & Physical Compatibility:

• Lever actuator with simulated roller design
• Chassis mount configuration
• Quick connect termination (connector size compatibility must be verified for specific applications)

Environmental & Lifecycle:

• Operating temperature range must encompass or exceed -25°C to 105°C
• Mechanical life rating should support the intended duty cycle

The Crouzet 83265846 qualifies as a substitute based on matching circuit configuration (SPST-NO), switch function (Off-Momentary), actuator type (Lever, Simulated Roller), mounting type (Chassis Mount), and exceeding the electrical ratings of the original component.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265846 is an active product suitable for substitution in applications requiring SPST-NO snap-action switch functionality. Key considerations:

Electrical Capability: The Crouzet part exceeds the current and AC voltage ratings of the original AM50064D43-A, providing margin for the specified 100mA at 125V AC requirement. DC voltage rating is not specified for the Crouzet part; applications requiring DC operation at 30V must be evaluated against actual load characteristics.

Mechanical Characteristics: Operating force is significantly lower (13gf vs. 60gf), and mechanical life is reduced (1,000,000 vs. 10,000,000 cycles). These differences may affect tactile feedback and long-term reliability in high-cycle applications.

Physical Integration: Termination connector sizes differ (0.250" vs. 0.187" quick connect). Harness or connector adaptation may be required for direct substitution.

Compliance & Availability: The Crouzet part carries RoHS Compliance and REACH Unaffected status, with active product availability. The original Panasonic part is obsolete with no ongoing supply.

Temperature Range: The Crouzet part supports -20°C to 125°C, which covers the original -25°C to 105°C range with extended upper temperature capability.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265846 directly replace the AM50064D43-A in existing assemblies?

A: Functional substitution is possible based on matching circuit configuration and switch function. However, physical integration requires verification of connector compatibility. The 0.250" (6.3mm) quick connect on the original part differs from the 0.187" (4.7mm) connector on the Crouzet part, necessitating harness modification or adapter evaluation.

Q: What are the key differences in operating characteristics?

A: The Crouzet part requires significantly less operating force (13gf vs. 60gf) and release force (2.039gf vs. 10gf). This results in lighter actuation but may affect tactile feedback and precision in applications sensitive to switch feel. Mechanical life is also lower (1,000,000 vs. 10,000,000 cycles).

Q: Is the Crouzet part suitable for DC applications?

A: The Crouzet 83265846 is rated for 5A AC at 250V. DC voltage rating is not specified in the provided data. Applications requiring 30V DC operation must be evaluated based on actual circuit requirements and load characteristics before substitution.

Q: What compliance certifications apply to the substitute part?

A: The Crouzet 83265846 is RoHS Compliant and REACH Unaffected. Both parts carry ECCN EAR99 classification and HTSUS code 8536.50.7000.

Q: How does temperature range affect substitution?

A: The Crouzet part operates from -20°C to 125°C, compared to the original -25°C to 105°C. The lower minimum temperature (-20°C vs. -25°C) may be a limitation in extreme cold environments. The extended upper range (125°C vs. 105°C) provides additional thermal margin.

Q: What is the impact of reduced mechanical life on component selection?

A: The Crouzet part is rated for 1,000,000 mechanical cycles versus 10,000,000 for the original. In applications with high actuation frequency, this tenfold reduction may require more frequent replacement or redesign to lower cycle rates.
