Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50045D33-A is based on the following critical electrical and mechanical parameters:

• Circuit configuration: SPDT topology
• Current rating: 100mA minimum capacity
• Voltage rating: 125V AC minimum, 30V DC minimum
• Actuator type: Lever or roller mechanism
• Mounting compatibility: Chassis mount configuration
• Termination style: Quick connect 0.250" (6.3mm) terminals
• Operating temperature range: -25°C to 105°C minimum
• Electrical life: 100,000 cycles minimum

The substitute part V3L-2163 from Honeywell Sensing and Productivity Solutions meets these core substitution criteria as an SPDT switch with compatible electrical ratings and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The V3L-2163 serves as a functional substitute for the obsolete AM50045D33-A based on matching SPDT circuit topology and compatible electrical specifications. The substitute part carries active product status and RoHS compliance certification, providing advantages for long-term supply chain continuity and regulatory compliance.

The primary consideration for substitution is termination style compatibility. The AM50045D33-A uses quick connect 0.250" (6.3mm) terminals, while the V3L-2163 employs solder termination. This difference requires evaluation of the target application's connection methodology and potential circuit board redesign.

The V3L-2163 current rating of 11A exceeds the original 100mA specification, providing additional electrical capacity margin. Voltage ratings for the substitute part are not specified in the provided data and must be confirmed through the manufacturer's complete technical documentation before final selection.

Frequently Asked Questions (FAQ)

Q: Can the V3L-2163 directly replace the AM50045D33-A without circuit modifications?

A: Direct mechanical and electrical substitution is possible based on matching SPDT configuration and current/voltage compatibility. However, termination style differs: the original uses quick connect terminals while the substitute uses solder connections. Circuit board modifications may be required.

Q: What are the key parameters that determine substitution eligibility?

A: SPDT circuit topology, current rating of 100mA minimum, voltage rating of 125V AC and 30V DC minimum, lever or roller actuator type, and operating temperature range of -25°C to 105°C are the primary criteria. Additional parameters including electrical life (100,000 cycles minimum) and mechanical life (10,000,000 cycles minimum) must also be satisfied.

Q: Why is the AM50045D33-A classified as obsolete?

A: The product status reflects discontinuation by the original manufacturer, Panasonic Electric Works. This classification necessitates identification of alternative components for applications requiring component replacement or new system designs.

Q: Does the V3L-2163 meet the same environmental specifications?

A: Both parts share MSL 1 (Unlimited) moisture sensitivity classification. The V3L-2163 carries RoHS compliance certification. Complete environmental and operating temperature specifications for the substitute part must be confirmed through manufacturer documentation.

Q: What is the significance of the higher current rating on the V3L-2163?

A: The 11A rating on the substitute part exceeds the original 100mA specification, providing additional electrical capacity. This represents a design margin advantage but does not affect substitution eligibility for applications operating within the original 100mA specification.
