DPA424G-TL Equivalent & Substitute Parts

Part Overview

The DPA424G-TL is a DPA-Switch® Converter IC designed for Power Over Ethernet (PoE) and Telecom applications. This component functions as a voltage regulator with a single output, rated for input voltages between 16V and 75V, delivering 220V output. The DPA424G-TL is classified as an obsolete product, which necessitates identification of active equivalent components to maintain design continuity and ensure long-term supply chain reliability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPA424G-TL is determined by strict electrical and mechanical parameter matching within the DPA-Switch® product family. The following criteria establish valid equivalency:

Electrical Parameters (Must Match):

• Input voltage range: 16V ~ 75V
• Output voltage: 220V
• Number of outputs: 1 output configuration
• Operating temperature range: -40°C ~ 125°C

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package type: 8-SMD, Gull Wing
• Supplier device package: 8-SMD

Functional Parameters (Must Match):

• Base product number: DPA424
• Application category: Power Over Ethernet and Telecom Applications
• Series designation: DPA-Switch®

The DPA424GN-TL satisfies all electrical, mechanical, and functional requirements for direct substitution. The primary distinction between the main part and its substitute relates to product status (obsolete versus active) and compliance certifications, not to electrical or mechanical performance characteristics.

Engineering Selection Recommendations

For New Designs and Production: The DPA424GN-TL is the appropriate selection for new product development and ongoing production. This part maintains active product status with Power Integrations, ensuring continued manufacturer support, documentation availability, and supply chain stability. The DPA424GN-TL carries RoHS Compliance certification, meeting current regulatory requirements for electronic components in most jurisdictions.

For Legacy System Support: The DPA424G-TL remains available in limited inventory (695 units) for field replacement and legacy system maintenance. However, given its obsolete classification, procurement should transition to the DPA424GN-TL for any new production quantities or long-term support requirements.

Compliance Considerations: The DPA424GN-TL provides RoHS Compliant status, whereas the DPA424G-TL is RoHS non-compliant. Organizations subject to RoHS regulations must use the DPA424GN-TL. Both parts maintain REACH Unaffected status and EAR99 export classification.

Moisture Handling: The DPA424GN-TL specifies MSL 4 (72 Hours), requiring controlled storage and handling conditions. The DPA424G-TL specifies MSL 1 (Unlimited), indicating less stringent moisture sensitivity requirements. Storage and assembly procedures must account for the MSL rating of the selected part.

Frequently Asked Questions (FAQ)

Q: Can the DPA424GN-TL directly replace the DPA424G-TL in existing designs?

A: Yes. The DPA424GN-TL provides electrical and mechanical equivalency to the DPA424G-TL. Both components share identical input voltage range (16V ~ 75V), output voltage (220V), operating temperature range (-40°C ~ 125°C), and 8-SMD package configuration. No circuit modifications are required for substitution.

Q: What is the primary reason for transitioning from DPA424G-TL to DPA424GN-TL?

A: The DPA424G-TL is classified as obsolete, indicating discontinued manufacturer support and limited long-term availability. The DPA424GN-TL is an active product with established supply channels and ongoing manufacturer commitment. For new production and future designs, the DPA424GN-TL ensures supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. The DPA424GN-TL is RoHS Compliant, while the DPA424G-TL is RoHS non-compliant. Organizations operating under RoHS regulations must use the DPA424GN-TL. Both parts maintain REACH Unaffected status.

Q: What packaging options are available for the DPA424GN-TL?

A: The DPA424GN-TL is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual assembly and automated pick-and-place operations.

Q: Does the moisture sensitivity level (MSL) difference affect component handling?

A: Yes. The DPA424GN-TL specifies MSL 4 (72 Hours), requiring controlled storage at specified temperature and humidity levels and limiting the time between package opening and component placement. The DPA424G-TL specifies MSL 1 (Unlimited), allowing indefinite storage without moisture control. Assembly procedures and storage protocols must comply with the MSL rating of the selected component.

Q: Is inventory availability a factor in part selection?

A: The DPA424GN-TL has significantly higher inventory availability (3255 units) compared to the DPA424G-TL (695 units). For volume production requirements, the DPA424GN-TL provides greater supply assurance.
