AM50064D33-A Equivalent & Substitute Parts

Part Overview

The AM50064D33-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 equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50064D33-A is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Momentary
• Actuator type: Lever with simulated roller
• Mounting type: Chassis mount
• Termination style: Quick connect

Electrical Performance Criteria:

• Current rating must equal or exceed 100mA
• Voltage rating (AC) must equal or exceed 125V
• Voltage rating (DC) must equal or exceed 30V

Mechanical Criteria:

• Operating force, release force, and travel distances must be compatible with the original application
• Operating temperature range must encompass or exceed -25°C to 105°C
• Mechanical life rating must support the intended duty cycle

The substitute part 83265846 (Crouzet V3D series) meets the primary functional and electrical criteria, with enhanced electrical performance (5A at 250V AC) and improved mechanical durability (1,000,000 mechanical cycles). However, mechanical parameter variations exist and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265846 (V3D series) is an active product suitable for substituting the obsolete AM50064D33-A in applications where the following conditions are met:

Electrical Compatibility: The substitute part exceeds the original electrical specifications with 5A at 250V AC capability, providing margin for the original 100mA at 125V AC requirement. For DC applications, the original part's 30V DC rating must be independently verified against the substitute's DC performance, as this specification is not provided for the Crouzet part.

Mechanical Compatibility: The substitute features lower operating and release forces (13gf and 2.039gf respectively, compared to 30gf and 5.099gf), which may affect tactile feedback and application suitability. The mechanical life rating of 1,000,000 cycles is lower than the original 10,000,000 cycles and must be evaluated against the intended duty cycle.

Physical Integration: The termination connector differs in size (0.187" vs. 0.250" quick connect), requiring connector adaptation or rewiring. Operating position and travel characteristics show minor variations that may require mechanical adjustment in the mounting assembly.

Compliance and Availability: The Crouzet part is RoHS Compliant and REACH Unaffected, with active product status ensuring ongoing availability. The original Panasonic part is obsolete, making substitution necessary for new production or long-term support.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265846 directly replace the AM50064D33-A without modification?

A: Direct replacement requires evaluation of three factors: (1) connector compatibility—the different quick connect sizes (0.187" vs. 0.250") may require adapter or rewiring; (2) mechanical force characteristics—the lower operating force may affect application behavior; (3) DC voltage rating—the substitute's DC performance is not specified and must be confirmed for DC applications.

Q: What are the key electrical differences between these parts?

A: The Crouzet substitute exceeds the original in AC performance (5A at 250V vs. 100mA at 125V). The original part specifies 30V DC operation; the substitute's DC rating is not provided and must be independently verified.

Q: How do the mechanical characteristics compare?

A: The Crouzet part requires significantly lower actuation force (13gf vs. 30gf) and has lower mechanical life (1,000,000 vs. 10,000,000 cycles). Operating position differs by approximately 0.073" (1.9mm). These differences may impact tactile response and long-term durability in high-cycle applications.

Q: Is the Crouzet part suitable for high-cycle applications?

A: The Crouzet part's 1,000,000 mechanical cycle rating is substantially lower than the original 10,000,000 cycles. Applications requiring extended cycle life should evaluate whether this reduced rating meets operational requirements.

Q: What compliance certifications apply to the substitute part?

A: The Crouzet 83265846 is RoHS Compliant and REACH Unaffected, with active product status. The original Panasonic part is obsolete.

Q: Are there temperature range considerations?

A: The Crouzet part operates from -20°C to 125°C, compared to the original -25°C to 105°C. The substitute provides a 20°C higher upper limit but a 5°C higher lower limit. Applications requiring operation below -20°C require alternative solutions.
