AVT32049 Equivalent & Substitute Parts

Part Overview

The AVT32049 is a snap action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with solder lug termination. This switch is rated for 3A at 125V AC and 30V DC, featuring a round pin plunger actuator with on-momentary function. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the AVT32049 reaches end-of-life status, inventory depletion, or when application requirements demand alternative electrical or mechanical specifications. The substitute parts listed maintain core SPDT functionality and chassis mount configuration while offering variations in current rating, voltage tolerance, and operational characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AVT32049 is determined by the following critical parameters:

Core Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-Momentary
• Actuator type must be Round Pin Plunger
• Mounting type must be Chassis Mount
• Termination style must be Solder Lug
• Operating position must be 0.330" (8.4mm)

Electrical Parameter Flexibility:

• Current rating may exceed 3A (higher ratings are acceptable for 125V AC applications)
• Voltage ratings must meet or exceed 125V AC minimum
• DC voltage rating may vary based on application requirements

Operational Characteristics:

• Operating temperature range may be broader than -25°C to 85°C
• Electrical and mechanical life specifications may differ based on duty cycle requirements
• Ingress protection rating may be enhanced without affecting core functionality

The substitute parts DB1C-A1AA, DC1C-A1AA, DC2C-A1AA, and DC3C-A1AA maintain the essential mechanical and electrical framework while offering variations in current handling capacity and environmental protection.

Parameter Comparison

Engineering Selection Recommendations

DC1C-A1AA (ZF Electronics) and DC2C-A1AA (ZF Electronics) are the primary active substitutes for the AVT32049. Both parts are currently in active production status with ROHS3 compliance certification. DC1C-A1AA provides 5A AC current capacity with 48V DC rating and IP67 environmental protection. DC2C-A1AA offers 10A AC current capacity, suitable for applications requiring higher current switching at 125V AC.

DB1C-A1AA (Hirose Electric Co Ltd) and DC3C-A1AA (Hirose Electric Co Ltd) are classified as obsolete products. While these parts maintain SPDT configuration and chassis mount characteristics, their obsolete status limits long-term availability and supply chain reliability. Selection of these parts should be restricted to legacy system maintenance where no alternative exists.

For new designs and ongoing production, DC1C-A1AA or DC2C-A1AA are preferred based on current and voltage requirements, as both manufacturers provide active product support and compliance documentation. The ZF Electronics parts offer extended operating temperature range (-40°C to 120°C) compared to the AVT32049 (-25°C to 85°C), providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can DC1C-A1AA directly replace AVT32049 in all applications?

A: DC1C-A1AA maintains identical mechanical configuration (chassis mount, solder lug termination, 0.330" operating position) and circuit function (SPDT, on-momentary). The 5A AC rating exceeds the 3A requirement, and 125V AC voltage rating matches the original specification. However, DC voltage rating differs (48V versus 30V), which may affect DC-only applications. Verify DC voltage requirements before substitution.

Q: What is the difference between DC1C-A1AA and DC2C-A1AA?

A: Both parts are manufactured by ZF Electronics with identical mechanical and thermal specifications. The primary difference is current rating: DC1C-A1AA is rated 5A AC and 1A DC, while DC2C-A1AA is rated 10A AC. Select DC2C-A1AA for applications requiring higher AC current switching capacity. DC2C-A1AA does not specify DC current rating.

Q: Why are DB1C-A1AA and DC3C-A1AA listed as obsolete?

A: Both parts are classified as obsolete by their respective manufacturers. Obsolete status indicates discontinued production and limited future availability. These parts should only be used for repair or maintenance of existing systems where no active alternative is available.

Q: Are there packaging differences between substitute parts?

A: AVT32049 is supplied in tube packaging. DC1C-A1AA and DC2C-A1AA are supplied in bulk packaging. DB1C-A1AA and DC3C-A1AA do not specify packaging format. Verify packaging requirements for your procurement and assembly processes.

Q: Do all substitute parts meet RoHS compliance?

A: AVT32049 is RoHS Compliant. DC1C-A1AA and DC2C-A1AA are ROHS3 Compliant, which represents an updated compliance standard. DB1C-A1AA and DC3C-A1AA do not specify RoHS status. For applications requiring RoHS certification, DC1C-A1AA or DC2C-A1AA are recommended.

Q: What is the significance of IP67 rating on DC1C-A1AA and DC2C-A1AA?

A: IP67 rating indicates dust-tight and waterproof protection. The AVT32049 does not specify ingress protection. If your application requires environmental sealing, DC1C-A1AA or DC2C-A1AA provide enhanced protection without affecting core switching functionality.
