AM50024D43-A Equivalent & Substitute Parts

Part Overview

The AM50024D43-A is a SPST-NC (Single Pole Single Throw - Normally Closed) snap-action switch manufactured by Panasonic Electric Works. This chassis-mounted 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 functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50024D43-A requires matching the following critical parameters:

• Circuit Configuration: SPST-NC topology must be maintained for proper system operation
• Switch Function: On-Mom (momentary) operation is required
• Actuator Type: Lever with simulated roller provides consistent tactile feedback and mechanical reliability
• Mounting Type: Chassis mount configuration ensures mechanical compatibility with existing enclosures
• Termination Style: Quick Connect - 0.250" (6.3mm) terminals must align with existing wiring harnesses
• Electrical Ratings: Substitute parts must meet or exceed the 100mA current capacity and voltage requirements of the original circuit
• Operating Temperature Range: Functional performance across -25°C to 105°C ensures reliability in the intended application environment

The Crouzet 83264626 satisfies these core substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83264626 is functionally equivalent to the AM50024D43-A for SPST-NC momentary switch applications. Both parts share identical circuit topology, switch function, actuator type, mounting configuration, and termination style.

The Crouzet substitute provides superior electrical performance with 12A AC current capacity versus the original 100mA rating, and 250V AC voltage rating versus 125V AC. This enhanced capacity ensures the substitute can handle the original application's electrical demands with margin.

The Crouzet 83264626 holds active product status with RoHS compliance and REACH unaffected certification, supporting long-term supply chain continuity and regulatory compliance requirements. The original AM50024D43-A, being obsolete, presents sourcing risk and lacks current environmental compliance documentation.

Mechanical life differs between the parts: the original specifies 10,000,000 cycles while the substitute specifies 1,000,000 cycles. Applications requiring extended mechanical cycling should evaluate this parameter against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83264626 directly replace the AM50024D43-A in existing assemblies?

A: Yes. Both switches share identical SPST-NC circuit configuration, On-Mom switch function, lever simulated roller actuator, chassis mount configuration, and 0.250" (6.3mm) quick-connect termination. Physical mounting and electrical connection are compatible.

Q: What are the key differences between these switches?

A: The Crouzet substitute offers higher current capacity (12A versus 100mA) and higher AC voltage rating (250V versus 125V). Operating force is lower (27gf versus 60gf), and mechanical life is lower (1,000,000 versus 10,000,000 cycles). The Crouzet part maintains active product status with current compliance certifications.

Q: Does the lower operating force of the Crouzet switch affect compatibility?

A: Lower operating force (27gf versus 60gf) means the Crouzet switch requires less finger pressure to actuate. This is a functional difference but does not prevent substitution. Applications with specific actuation force requirements should evaluate this parameter against system design specifications.

Q: Is the difference in mechanical life significant for this application?

A: The original specifies 10,000,000 cycles while the substitute specifies 1,000,000 cycles. For applications with low to moderate actuation frequency, this difference is not limiting. High-cycle applications should calculate expected service life based on actual duty cycle and compare against the 1,000,000-cycle rating.

Q: What compliance advantages does the Crouzet substitute offer?

A: The Crouzet 83264626 is RoHS Compliant and REACH Unaffected, supporting current environmental and regulatory requirements. The obsolete AM50024D43-A lacks current compliance documentation, making the Crouzet substitute preferable for new designs and long-term supply chain planning.

Q: Are there any temperature range considerations?

A: The Crouzet substitute operates across -20°C to 125°C versus the original -25°C to 105°C. The substitute's upper temperature limit is 20°C higher, providing better performance in elevated-temperature environments. The original's lower temperature limit is 5°C lower; applications requiring operation below -20°C should verify the original specification against actual requirements.
