DPA424P Equivalent & Substitute Parts Reference

Part Overview

The DPA424P is a DPA-Switch® Converter IC designed for Power Over Ethernet (PoE) and Telecom applications. This integrated voltage regulator provides single-output conversion with input voltage range of 16V to 75V and fixed 220V output. The device is packaged in 8-PDIP through-hole configuration and operates across the industrial temperature range of -40°C to 125°C.

The DPA424P is classified as obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this component remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPA424P are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Input voltage range: 16V ~ 75V
• Output voltage: 220V
• Number of outputs: 1 output configuration

Mechanical Parameters (Must Match):

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting method: Through Hole
• Supplier device package: 8-PDIP

Operational Parameters (Must Match):

• Operating temperature range: -40°C ~ 125°C
• Series family: DPA-Switch®

The DPA424PN qualifies as a direct substitute because it maintains identical electrical specifications, mechanical packaging, and operational characteristics while offering improved product status and compliance profile.

Engineering Selection Recommendations

DPA424PN as Primary Substitute:

The DPA424PN is the direct equivalent for DPA424P applications. Selection of DPA424PN is supported by the following engineering factors:

1. Functional Equivalence: All critical electrical parameters (input voltage range 16V–75V, output voltage 220V, single output) are identical to the original DPA424P.

2. Physical Compatibility: The 8-DIP through-hole package with 0.300" (7.62mm) spacing ensures direct PCB footprint compatibility without layout modifications.

3. Product Status: DPA424PN maintains Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity compared to the Obsolete DPA424P.

4. Compliance Enhancement: DPA424PN achieves RoHS Compliance status, whereas DPA424P is RoHS non-compliant. This provides regulatory advantage for new designs and updated manufacturing environments.

5. Operational Consistency: Operating temperature range (-40°C to 125°C), moisture sensitivity level (MSL 1), REACH status, and export classification (EAR99) remain unchanged, confirming full operational compatibility.

6. Packaging Options: DPA424PN is supplied in Tube packaging, providing standard component handling and storage compatibility with modern supply chain practices.

Frequently Asked Questions (FAQ)

Q: Can DPA424PN be used as a direct replacement for DPA424P in existing designs?

A: Yes. DPA424PN is a direct substitute with identical electrical specifications (16V–75V input, 220V output), package type (8-DIP), and operating temperature range (-40°C to 125°C). No circuit modifications or PCB layout changes are required.

Q: What is the primary advantage of switching from DPA424P to DPA424PN?

A: DPA424PN offers Active product status with ongoing manufacturer support, compared to the Obsolete status of DPA424P. Additionally, DPA424PN achieves RoHS Compliance, providing regulatory advantage and improved environmental compliance.

Q: Are the pinouts identical between DPA424P and DPA424PN?

A: Yes. Both devices use the 8-PDIP package configuration with identical pin assignments. Direct PCB substitution is possible without rewiring or layout modifications.

Q: What is the difference between DPA424P and DPA424PN packaging?

A: DPA424P packaging type is not specified in the provided data. DPA424PN is supplied in Tube packaging, which is standard for component distribution and storage.

Q: Is DPA424PN available in the same through-hole mounting configuration?

A: Yes. DPA424PN uses Through Hole mounting type with 8-DIP (0.300", 7.62mm) package, identical to DPA424P. Both are suitable for traditional PCB assembly methods.

Q: Do DPA424P and DPA424PN have the same moisture sensitivity level?

A: Yes. Both devices have Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates minimal moisture sensitivity and standard handling requirements.

Q: Are there any export or regulatory differences between these parts?

A: No. Both DPA424P and DPA424PN share identical ECCN (EAR99), HTSUS code (8542.39.0001), and REACH status (REACH Unaffected). Export and regulatory classifications remain unchanged.
