DPA422GN Equivalent & Substitute Parts

Part Overview

The DPA422GN is a DPA-Switch® Converter IC designed for Power Over Ethernet (PoE) and Telecom applications. This voltage regulator IC features a single output configuration in an 8-SMD, Gull Wing surface mount package. The device operates across an input voltage range of 16V to 75V with a 220V output specification and supports operating temperatures from -40°C to 125°C.

The DPA422GN is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPA422GN 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
• Number of outputs: 1 (single output configuration)
• Operating temperature range: -40°C ~ 125°C

Mechanical Parameters:

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

Functional Parameters:

• Application category: Power Over Ethernet and Telecom Converter
• Series family: DPA-Switch®

The DPA423GN-TL meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format (Tape & Reel versus standard packaging) and product status (Active versus Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The DPA423GN-TL is a direct functional and electrical equivalent to the DPA422GN. Both devices share identical electrical specifications, operating parameters, and physical package dimensions. The DPA423GN-TL is the appropriate substitute for the discontinued DPA422GN.

Key Selection Factors:

1. Product Status: The DPA423GN-TL maintains Active product status with confirmed inventory availability (19,499 Pcs), whereas the DPA422GN is discontinued. For new designs and production continuity, the DPA423GN-TL is the recommended selection.

2. Compliance and Certifications: The DPA423GN-TL carries RoHS Compliant certification. Both devices maintain REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory compliance for PoE and Telecom applications.

3. Packaging Consideration: The DPA423GN-TL is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. If standard packaging is required, verify availability through component distributors.

4. Moisture Sensitivity: Both parts maintain MSL 4 (72 Hours) rating, requiring identical handling and storage protocols.

Frequently Asked Questions (FAQ)

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