AM50065D43-A Equivalent & Substitute Parts

Part Overview

The AM50065D43-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This component is rated for 100mA at 125V AC and 30V DC, featuring a lever/roller actuator with momentary off operation. The part 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 AM50065D43-A is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration must be SPST-NO
• Switch function must be Off-Mom (momentary operation)
• Actuator type must include lever and/or roller mechanism
• Mounting type must be chassis mount
• Termination must be quick connect style

Electrical Compatibility Criteria:

• Current rating must meet or exceed 100mA
• AC voltage rating must meet or exceed 125V
• DC voltage rating must meet or exceed 30V
• Operating temperature range must encompass or exceed -25°C to 105°C

Mechanical Compatibility Criteria:

• Operating position must be within acceptable mechanical envelope
• Pretravel, differential travel, and overtravel specifications must be compatible with application mechanical design

The Crouzet 83265847 qualifies as a substitute based on matching circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (lever/roller), mounting type (chassis mount), and termination style (quick connect). The substitute exceeds electrical ratings with 5A at 250V AC capability and provides superior operating temperature range (-20°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265847 is an active product with current manufacturing support, providing a functional substitute for the obsolete AM50065D43-A. The substitute demonstrates superior electrical ratings (5A at 250V AC versus 100mA at 125V AC) and extended operating temperature range (-20°C to 125°C versus -25°C to 105°C). Both components share identical circuit configuration, switch function, actuator type, and mounting methodology.

Design consideration: The quick connect termination differs in size (0.187" versus 0.250"), requiring mechanical interface verification. The Crouzet component exhibits lower mechanical life rating (1,000,000 cycles versus 10,000,000 cycles), which must be evaluated against application duty cycle requirements. The substitute carries RoHS compliance and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265847 directly replace the AM50065D43-A in existing designs?

A: Functional substitution is possible based on matching circuit configuration, switch function, and actuator type. Mechanical interface compatibility must be verified due to quick connect termination size difference (0.187" versus 0.250"). Mounting hole patterns and panel cutout dimensions should be confirmed before implementation.

Q: What are the electrical compatibility considerations?

A: The Crouzet substitute exceeds the original part's electrical ratings. Applications operating at 100mA and 125V AC are fully compatible. The substitute's 5A capacity at 250V AC provides design margin for future upgrades or higher-load applications.

Q: How do the mechanical specifications compare?

A: Operating positions are nearly identical (0.806" versus 0.815"), indicating compatible mechanical envelopes. Differential travel and overtravel values are within 0.004" difference, acceptable for most chassis-mount switch applications. Mechanical life differs significantly (1,000,000 versus 10,000,000 cycles); applications requiring extended cycle life should evaluate duty cycle requirements.

Q: Are there regulatory or compliance differences?

A: The Crouzet component is RoHS compliant and REACH unaffected, meeting current environmental regulations. The original Panasonic part's compliance status is not specified. New designs should prioritize the Crouzet component for regulatory alignment.

Q: What is the impact of the different quick connect sizes?

A: The 0.187" (4.7mm) Crouzet termination differs from the 0.250" (6.3mm) original. Existing wiring harnesses and connector blocks designed for 0.250" terminals require adapter solutions or rewiring. Mechanical stress analysis should verify that the smaller terminal diameter is acceptable for the application's current and vibration environment.
