AM50624D33-A Equivalent & Substitute Parts

Part Overview

The AM50624D33-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device with chassis mount termination. This component is rated for 6A AC at 125V and features a lever with simulated roller actuator. The product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM50624D33-A must satisfy the following core substitution criteria based on provided electrical and mechanical parameters:

Primary Compatibility Requirements:

• Circuit configuration: SPST-NC (single-pole, single-throw, normally-closed)
• Switch function: On-Mom (momentary operation)
• Actuator type: Lever with simulated roller mechanism
• Mounting type: Chassis mount
• Termination style: Quick Connect connector

Electrical Compatibility Parameters:

• Current rating must equal or exceed 6A AC at the operating voltage
• Voltage rating must equal or exceed 125V AC
• Operating temperature range must encompass or exceed -25°C to 105°C

Mechanical Compatibility Parameters:

• Operating force, pretravel, differential travel, and overtravel must be within acceptable tolerance ranges for the application
• Mechanical life rating must support the intended duty cycle

The substitute part Crouzet 83264646 meets these core criteria with enhanced electrical ratings (12A AC at 250V), compatible actuator and mounting specifications, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Substitute Viability:

The Crouzet 83264646 functions as a direct substitute for the obsolete AM50624D33-A based on matching circuit configuration (SPST-NC), switch function (On-Mom), actuator type (lever with simulated roller), and mounting method (chassis mount). The substitute provides superior electrical ratings (12A AC at 250V versus 6A AC at 125V), ensuring safe operation in the original application envelope.

Compliance Considerations:

The Crouzet 83264646 holds active product status with RoHS compliance certification, supporting long-term supply chain continuity and regulatory alignment. The original Panasonic part, being obsolete, presents sourcing risk and lacks current compliance documentation.

Mechanical Life Trade-off:

The substitute exhibits a 10:1 reduction in mechanical life rating (1,000,000 cycles versus 10,000,000 cycles). This parameter must be evaluated against actual application duty cycle requirements. Applications requiring extended mechanical life beyond 1,000,000 cycles may require alternative solutions.

Connector Compatibility:

The termination style differs between parts: AM50624D33-A uses 0.250" (6.3mm) quick connect terminals, while the Crouzet substitute uses 0.187" (4.7mm) terminals. Connector adaptation or harness modification is necessary for direct substitution.

Temperature Range Consideration:

The Crouzet substitute operates to 125°C maximum (versus 105°C for the original) but has a minimum operating temperature of -20°C (versus -25°C for the original). Applications requiring operation below -20°C require verification of substitute suitability.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264646 directly replace the AM50624D33-A without modification?

A: Functional substitution is possible with connector adaptation. The quick connect terminal sizes differ (0.250" versus 0.187"), requiring either connector replacement or harness modification. All electrical and mechanical functions are compatible.

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

A: The original part is rated for 10,000,000 cycles; the substitute is rated for 1,000,000 cycles. This 10:1 difference must be evaluated against the application's actual switching frequency and expected service life. Applications with lower duty cycles remain unaffected.

Q: Are there temperature range limitations with the substitute?

A: The substitute operates from -20°C to 125°C, compared to the original's -25°C to 105°C range. The substitute cannot be used in applications requiring operation below -20°C. The upper temperature limit is 20°C higher, providing additional margin in high-temperature environments.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The Crouzet 83264646 is RoHS compliant and holds active product status, ensuring compliance with current environmental and supply chain regulations. The obsolete Panasonic part lacks current compliance documentation.

Q: What is the impact of the different operating force values?

A: The substitute requires 27gf operating force versus 30gf for the original. This 3gf reduction is within typical tolerance ranges for lever-actuated switches and does not affect functional compatibility. User actuation effort will be marginally lighter.

Q: How do the operating position and travel parameters affect substitution?

A: The substitute has a larger operating position (0.803" versus 0.730") and greater overtravel (0.070" versus 0.055"), while maintaining a tighter differential travel (0.031" versus 0.040"). These differences must be verified against mechanical clearances and actuation geometry in the specific application.
