DPA425G-TL Equivalent & Substitute Parts

Part Overview

The DPA425G-TL is a DPA-Switch® Converter IC designed for Power Over Ethernet (PoE) and Telecom applications. This single-output voltage regulator operates across a wide input voltage range of 16V to 75V and delivers a 220V output. The device is packaged in an 8-SMD, Gull Wing surface mount configuration.

The DPA425G-TL is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this component was previously specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPA425G-TL is determined by the following critical parameters:

Electrical Compatibility:

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

Mechanical Compatibility:

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

Functional Compatibility:

• Series: DPA-Switch®
• Applications: Converter, Power Over Ethernet and Telecom Applications
• Manufacturer: Power Integrations

The DPA425GN-TL meets all electrical, mechanical, and functional compatibility criteria. Both parts share identical input/output voltage specifications, operating temperature range, package configuration, and application focus. The primary distinction is product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Future Applications:

The DPA425GN-TL is the appropriate selection for new designs and forward-looking applications. This part carries Active product status, ensuring long-term availability and manufacturer support. The DPA425GN-TL is RoHS Compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. Both REACH Unaffected status and EAR99 export classification are identical between the two parts.

For Legacy System Maintenance and Repair:

The DPA425G-TL remains available in inventory (907 units) for applications where the original specification must be maintained. However, the obsolete product status indicates that future availability cannot be guaranteed. The DPA425G-TL is RoHS non-compliant, which may present regulatory constraints in certain markets or applications subject to environmental compliance mandates.

Compliance Considerations:

The transition from DPA425G-TL to DPA425GN-TL involves a change in RoHS compliance status. Organizations operating under RoHS directives or similar environmental regulations should prioritize the DPA425GN-TL. The Moisture Sensitivity Level (MSL) differs between parts: DPA425G-TL has MSL 1 (Unlimited), while DPA425GN-TL has MSL 4 (72 Hours). This affects storage and handling procedures but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical specifications (16V–75V input, 220V output, single output), operating temperature range (-40°C to 125°C), and mechanical configuration (8-SMD, Gull Wing surface mount package). The parts are functionally interchangeable from an electrical and mechanical standpoint.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturer support and long-term availability. The DPA425G-TL is classified as Obsolete, meaning Power Integrations no longer manufactures this part. The DPA425GN-TL is Active, ensuring continued production and availability. For new designs, the Active part is the appropriate choice.

Q: Why does the RoHS compliance status differ between these parts?

A: The DPA425G-TL predates RoHS compliance requirements and is marked as RoHS non-compliant. The DPA425GN-TL is RoHS Compliant, meeting Directive 2011/65/EU and similar environmental regulations. Organizations subject to RoHS mandates must use the DPA425GN-TL.

Q: What does the Moisture Sensitivity Level (MSL) difference mean for handling?

A: MSL 1 (DPA425G-TL) indicates unlimited shelf life without moisture control. MSL 4 (DPA425GN-TL) requires storage in controlled humidity conditions and limits shelf life to 72 hours after opening the moisture barrier bag. This affects storage, handling, and assembly procedures but does not impact electrical performance or compatibility.

Q: Are there packaging differences between DPA425G-TL and DPA425GN-TL?

A: The DPA425GN-TL is available in Cut Tape (CT) and Digi-Reel® packaging options. The DPA425G-TL packaging specification is not detailed in available documentation. Both parts use the same 8-SMD, Gull Wing package configuration for the component itself.

Q: Which part should be selected for a new PoE converter design?

A: The DPA425GN-TL is the appropriate selection for new designs. It offers Active product status, RoHS compliance, and higher inventory availability (3914 units vs. 907 units). The electrical and mechanical specifications are identical to the DPA425G-TL, ensuring design compatibility while providing regulatory compliance and long-term availability.
