DPA425G Equivalent & Substitute Parts Reference

Part Overview

The DPA425G 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 DPA425G 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 DPA425G is determined by strict electrical and mechanical parameter matching within the DPA-Switch® converter family. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Input voltage range: 16V ~ 75V
• Output voltage: 220V
• Number of outputs: 1 (single 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

Base Product Compatibility:

• All substitutes must share the same base product number (DPA425) within the DPA-Switch® series

The DPA425GN-TL qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters specified above.

Engineering Selection Recommendations

The DPA425GN-TL is the direct equivalent substitute for the obsolete DPA425G. Selection of the DPA425GN-TL is based on the following engineering factors:

Product Status: The DPA425G is classified as obsolete, while the DPA425GN-TL maintains active product status with current manufacturing support and availability (3914 Pcs in stock versus 1078 Pcs for the obsolete variant).

Regulatory Compliance: The DPA425GN-TL achieves RoHS Compliance, whereas the DPA425G is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Electrical and Mechanical Compatibility: All critical electrical parameters (input voltage range 16V–75V, output voltage 220V, single output, operating temperature -40°C to 125°C) and mechanical specifications (8-SMD Gull Wing surface mount package) are identical between the two parts.

Packaging and Distribution: The DPA425GN-TL is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing enhanced supply chain flexibility compared to the DPA425G.

For new designs and legacy system replacements, the DPA425GN-TL is the appropriate selection within the DPA-Switch® converter family.

Frequently Asked Questions (FAQ)

Q: Can the DPA425GN-TL be used as a direct replacement for the DPA425G in existing designs?

A: Yes. The DPA425GN-TL is electrically and mechanically identical to the DPA425G. All electrical parameters (input voltage 16V–75V, output voltage 220V, single output) and mechanical specifications (8-SMD Gull Wing package, surface mount) are equivalent. The DPA425GN-TL is the active production equivalent.

Q: What is the difference between the DPA425G and DPA425GN-TL?

A: The primary differences are product status and regulatory compliance. The DPA425G is obsolete and RoHS non-compliant, while the DPA425GN-TL is an active product with RoHS Compliance. Electrical and mechanical specifications are identical. The DPA425GN-TL also offers improved packaging options (Cut Tape and Digi-Reel®).

Q: Are there any package or pinout differences between these parts?

A: No. Both the DPA425G and DPA425GN-TL use the 8-SMD Gull Wing package with identical pinout and mechanical dimensions. They are pin-for-pin compatible.

Q: What is the moisture sensitivity level (MSL) difference?

A: The DPA425G has MSL 1 (Unlimited), while the DPA425GN-TL has MSL 4 (72 Hours). This indicates the DPA425GN-TL requires controlled moisture exposure during storage and handling. Standard moisture control procedures for MSL 4 components apply.

Q: Is the DPA425GN-TL suitable for Power Over Ethernet (PoE) and Telecom applications?

A: Yes. The DPA425GN-TL is designed for PoE and Telecom converter applications, identical to the DPA425G. The 16V–75V input range and 220V output are standard for these applications.

Q: What certifications and compliance standards apply to the DPA425GN-TL?

A: The DPA425GN-TL is RoHS Compliant, REACH Unaffected, and classified under ECCN EAR99. HTSUS code is 8542.39.0001. The DPA425G is RoHS non-compliant but shares the same REACH and ECCN status.
