DPA422GN-TL Equivalent & Substitute Parts

Part Overview

The DPA422GN-TL is a DPA-Switch® Converter IC designed for Power Over Ethernet and Telecom Applications. This single-output voltage regulator operates across an 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 and is rated for operating temperatures from -40°C to 125°C.

The DPA422GN-TL is classified as an obsolete product. 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 DPA422GN-TL are identified based on strict electrical and mechanical parameter matching within the DPA-Switch® product family. The substitution criteria are:

Electrical Parameters (Must Match):

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

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package type: 8-SMD, Gull Wing
• Moisture sensitivity level: 4 (72 Hours)

Functional Parameters (Must Match):

• Application category: Power Over Ethernet and Telecom Applications
• Converter topology: DPA-Switch® series

The DPA423GN-TL meets all substitution criteria and is classified as an active product, making it a direct functional equivalent to the obsolete DPA422GN-TL.

Parameter Comparison

Engineering Selection Recommendations

The DPA423GN-TL is the direct substitute for the obsolete DPA422GN-TL. Both devices share identical electrical specifications, thermal ratings, and mechanical packaging. The DPA423GN-TL is currently in active production status, ensuring long-term availability and supply chain continuity.

The DPA423GN-TL carries RoHS Compliance certification, providing environmental regulatory alignment for new designs and production runs. Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications.

The primary difference between the two parts is packaging format: the DPA422GN-TL is supplied in bulk packaging, while the DPA423GN-TL is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or thermal performance and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the DPA423GN-TL directly replace the DPA422GN-TL in existing designs?

A: Yes. The DPA423GN-TL is electrically and mechanically identical to the DPA422GN-TL. Both devices operate across the same input voltage range (16V ~ 75V), deliver identical output voltage (220V), and are housed in the same 8-SMD, Gull Wing package. No design modifications are required.

Q: What is the difference between the DPA422GN-TL and DPA423GN-TL?

A: The devices are functionally equivalent. The primary differences are product status (DPA422GN-TL is obsolete; DPA423GN-TL is active) and packaging format (bulk versus Tape & Reel). The DPA423GN-TL also carries RoHS Compliance certification.

Q: Are there any thermal or operating condition differences?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C and maintain the same Moisture Sensitivity Level (MSL) rating of 4 (72 Hours).

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

A: No. Tape & Reel packaging is a supply and assembly format only. It does not affect electrical performance, thermal characteristics, or reliability of the component.

Q: Are compliance certifications identical?

A: Both parts maintain REACH Unaffected status and identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The DPA423GN-TL additionally carries RoHS Compliance certification.
