Key Parameters

Substitute Part Grouping Explanation

Substitution of the AV37049 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT (Single Pole Double Throw)
• Switch Function: Must be On-Momentary
• Actuator Type: Must be Round Pin Plunger
• Mounting Type: Must be Through Hole, Right Angle
• Termination Style: Must be PC Pin
• Current Rating: Must support minimum 3A AC operation
• Voltage Rating: Must support minimum 125V AC

The Honeywell Sensing and Productivity Solutions ZV50B50A01 meets these core substitution criteria. While it provides higher current capacity (6A AC) and extended mechanical life specifications, it maintains functional compatibility with the AV37049 in applications requiring SPDT snap action switching with right-angle through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

The ZV50B50A01 serves as a functional substitute for the AV37049 based on matching circuit topology, actuator configuration, and mounting interface. Both components are classified as obsolete products.

Selection between these parts should account for the following provided specifications:

• The ZV50B50A01 provides higher current capacity (6A AC versus 3A AC/DC), suitable for applications requiring increased current margin
• The ZV50B50A01 operates across a wider temperature range (-40°C to 120°C versus -25°C to 85°C)
• The AV37049 provides higher electrical life rating (50,000 cycles versus 10,000 cycles)
• The ZV50B50A01 provides significantly higher mechanical life (10,000,000 cycles versus 500,000 cycles)
• The ZV50B50A01 is RoHS Compliant; RoHS status for the AV37049 is not specified in available data

Both components carry ECCN EAR99 classification and HTSUS code 8536.50.7000, with MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the ZV50B50A01 directly replace the AV37049 in existing applications?

A: The ZV50B50A01 maintains functional compatibility in applications requiring SPDT snap action switching with 125V AC operation and right-angle through-hole mounting. Physical fit and electrical performance are compatible. Verify that the higher current capacity and different operating force (65gf versus 100gf) do not conflict with application requirements.

Q: What are the key differences between these parts?

A: The primary differences are current rating (6A versus 3A), operating force (65gf versus 65gf), electrical life (10,000 versus 50,000 cycles), mechanical life (10,000,000 versus 500,000 cycles), and operating temperature range (-40°C to 120°C versus -25°C to 85°C).

Q: Are there packaging or mounting considerations?

A: Both parts use PC Pin termination and right-angle through-hole mounting. Packaging specifications are not provided in the available data. Confirm physical dimensions and PCB hole spacing compatibility with your application.

Q: What is the significance of the obsolete product status?

A: Both the AV37049 and ZV50B50A01 are classified as obsolete. Inventory availability may be limited. Confirm long-term supply chain viability for production applications.

Q: How do the electrical life ratings affect component selection?

A: The AV37049 provides 50,000 electrical cycles versus 10,000 for the ZV50B50A01. For applications with high switching frequency, the AV37049 specification may be preferable if available. The ZV50B50A01 compensates with significantly higher mechanical life (10,000,000 cycles).
