DPA424G Equivalent & Substitute Parts Reference

Part Overview

The DPA424G is a DPA-Switch® Converter IC designed for Power Over Ethernet (PoE) and Telecom applications. This device functions as a voltage regulator with single output capability, converting input voltages in the 16V to 75V range to a 220V output. The DPA424G is classified as an obsolete product, which necessitates identification of active equivalent alternatives for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPA424G is determined by strict alignment with the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Manufacturer: Power Integrations (same manufacturer ensures design compatibility)
• Base Product Number: DPA424 (indicates same core IC architecture)
• Input Voltage Range: 16V ~ 75V (functional voltage specification)
• Output Voltage: 220V (output specification)
• Number of Outputs: 1 (output configuration)
• Operating Temperature Range: -40°C ~ 125°C (thermal operating envelope)
• Package / Case: 8-SMD, Gull Wing (physical and electrical footprint)
• Mounting Type: Surface Mount (assembly compatibility)

The DPA424GN-TL qualifies as a direct substitute based on complete alignment across all critical parameters. The primary distinction between the main part and its substitute relates to product status (obsolete versus active) and packaging format (standard versus Cut Tape/Digi-Reel®), along with associated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Continued Production:

The DPA424GN-TL is the appropriate selection for applications currently using or requiring the DPA424G. This substitute maintains complete electrical and mechanical compatibility while offering the advantage of active product status from Power Integrations. The DPA424GN-TL is actively manufactured and supported, ensuring long-term availability and supply chain stability.

Compliance Considerations:

The DPA424GN-TL provides RoHS Compliance, which aligns with current regulatory requirements in many markets. Organizations subject to RoHS directives should prioritize the DPA424GN-TL over the obsolete DPA424G.

Packaging and Handling:

The DPA424GN-TL is supplied in Cut Tape (CT) and Digi-Reel® formats, which are standard for high-volume manufacturing environments. The increased Moisture Sensitivity Level (MSL 4, 72 Hours) compared to the DPA424G (MSL 1, Unlimited) requires adherence to standard moisture control protocols during storage and assembly. This is standard industry practice and does not impact functional performance when proper handling procedures are followed.

Frequently Asked Questions (FAQ)

Q: Can DPA424GN-TL be used as a direct replacement for DPA424G in existing designs?

A: Yes. The DPA424GN-TL is electrically and mechanically identical to the DPA424G across all functional parameters: input voltage range (16V ~ 75V), output voltage (220V), single output configuration, operating temperature range (-40°C ~ 125°C), and 8-SMD Gull Wing package. No circuit modifications are required.

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

A: The DPA424G is classified as obsolete, meaning Power Integrations no longer manufactures this variant. The DPA424GN-TL is the active equivalent, ensuring continued availability, manufacturing support, and compliance with current regulatory standards including RoHS.

Q: Are there differences in handling or storage between these two parts?

A: Yes. The DPA424G has MSL 1 (Unlimited moisture sensitivity), while the DPA424GN-TL has MSL 4 (72-hour moisture sensitivity). The DPA424GN-TL requires standard moisture control during storage and assembly, consistent with industry practices for MSL 4 components. This does not affect electrical performance or reliability when proper handling is observed.

Q: Is the DPA424GN-TL RoHS compliant?

A: Yes. The DPA424GN-TL is RoHS Compliant, whereas the DPA424G is RoHS non-compliant. This makes the DPA424GN-TL suitable for applications and markets with RoHS requirements.

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

A: The DPA424GN-TL is supplied in Cut Tape (CT) and Digi-Reel® formats, which are standard for automated assembly and high-volume production environments.

Q: Are there any functional differences in Power Over Ethernet or Telecom applications?

A: No. Both the DPA424G and DPA424GN-TL are designed for identical applications: Power Over Ethernet and Telecom voltage regulation. All functional specifications for these applications are identical.
