DPA423G-TL Equivalent & Substitute Parts

Part Overview

The DPA423G-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 housed in an 8-SMD, Gull Wing surface mount package.

The DPA423G-TL is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this converter topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPA423G-TL are identified based on strict electrical and mechanical parameter matching within the DPA-Switch® product family. The substitution criteria are:

Electrical Parameters:

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

Mechanical Parameters:

• Package type: 8-SMD, Gull Wing
• Mounting type: Surface Mount
• Base product number: DPA423

Compliance Parameters:

• Manufacturer: Power Integrations
• Series: DPA-Switch®
• ECCN classification: EAR99
• HTSUS code: 8542.39.0001

Parts meeting all these criteria are classified as direct substitutes. Packaging format (tube versus tape & reel) does not affect electrical or mechanical compatibility and represents a logistics variation only.

Parameter Comparison

Engineering Selection Recommendations

DPA423GN-TL is the direct substitute for DPA423G-TL. Both parts share identical electrical specifications, mechanical packaging, and regulatory classifications. The DPA423GN-TL is currently in active production status with substantial inventory availability (19,499 pcs), whereas the DPA423G-TL is discontinued.

Compliance Considerations:

The DPA423GN-TL carries RoHS Compliant certification, whereas the original DPA423G-TL is RoHS non-compliant. This represents an improvement in environmental compliance for new designs and procurement cycles. Both parts maintain REACH Unaffected status and EAR99 export classification.

Moisture Sensitivity:

The DPA423GN-TL specifies Moisture Sensitivity Level (MSL) 4 with a 72-hour floor life requirement, compared to MSL 1 (unlimited) for the DPA423G-TL. This difference requires appropriate handling and storage protocols during component receipt and assembly operations.

Packaging Format:

The DPA423GN-TL is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes. The original DPA423G-TL packaging format is not specified in the provided data. Tape & Reel packaging is compatible with standard pick-and-place equipment used in surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can DPA423GN-TL be used as a direct replacement for DPA423G-TL in existing designs?

A: Yes. Both parts are identical in electrical performance, output specifications, and mechanical form factor. The DPA423GN-TL operates across the same 16V to 75V input range, delivers 220V output, and uses the same 8-SMD, Gull Wing package. No circuit modifications are required.

Q: What is the difference between DPA423G-TL and DPA423GN-TL?

A: The primary differences are product status and compliance certifications. DPA423G-TL is discontinued; DPA423GN-TL is active production. DPA423GN-TL is RoHS Compliant, while DPA423G-TL is RoHS non-compliant. Both parts are functionally equivalent for PoE and Telecom converter applications.

Q: Does the Tape & Reel packaging of DPA423GN-TL affect compatibility?

A: No. Tape & Reel is a standard packaging format for surface mount components and is fully compatible with automated assembly equipment. It does not affect electrical or mechanical performance.

Q: What is the Moisture Sensitivity Level (MSL) difference, and does it matter?

A: DPA423GN-TL has MSL 4 (72-hour floor life), while DPA423G-TL has MSL 1 (unlimited). MSL 4 requires that components be used within 72 hours of bag opening under controlled humidity conditions. This is a standard handling requirement for modern surface mount components and does not affect performance if proper storage protocols are followed.

Q: Are there any regulatory or export restrictions for DPA423GN-TL?

A: No. Both parts carry EAR99 export classification and REACH Unaffected status, identical to the original part. No additional regulatory considerations apply to the substitute.

Q: Why is DPA423G-TL discontinued?

A: Product discontinuation information is not provided in the technical data. Contact Power Integrations directly for lifecycle and discontinuation details.
