DPA425P Equivalent & Substitute Parts Reference

Part Overview

The DPA425P is a DPA-Switch® Converter IC designed for Power Over Ethernet (PoE) and Telecom applications. This device functions as a voltage regulator with single output capability, rated for input voltages between 16V and 75V with a 220V output specification. The DPA425P is classified as an obsolete product, necessitating identification of active equivalent parts for new designs and ongoing system support. The availability of direct substitutes ensures continuity in component sourcing and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPA425P is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Input voltage range (16V ~ 75V), output voltage (220V), and single output configuration must remain identical.

Physical Compatibility: Package type (8-DIP with 0.300" / 7.62mm pitch) and through-hole mounting type ensure direct PCB compatibility without layout modifications.

Functional Classification: Both parts belong to the DPA-Switch® series and serve identical Power Over Ethernet and Telecom converter applications.

Environmental Ratings: Operating temperature range (-40°C ~ 125°C) and moisture sensitivity level (MSL 1) must match.

The DPA425PN is identified as a direct substitute based on complete alignment with all specified parameters. The primary distinction between DPA425P and DPA425PN is product status and packaging format, with DPA425PN representing the active production equivalent.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: DPA425PN is the appropriate selection. This part maintains active product status with Power Integrations, ensuring long-term availability and technical support. The RoHS Compliant certification of DPA425PN aligns with current regulatory requirements for electronic components in most markets.

For Legacy System Maintenance: DPA425P remains functionally equivalent to DPA425PN across all critical electrical and mechanical parameters. However, sourcing of DPA425P is limited due to obsolete status. DPA425PN provides identical performance with improved compliance posture.

Compliance Considerations: DPA425PN carries RoHS Compliant certification, whereas DPA425P is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification. Selection should account for end-application regulatory requirements.

Inventory and Supply Chain: DPA425PN demonstrates higher current inventory availability (1805 Pcs) compared to DPA425P (807 Pcs), supporting supply chain continuity for production environments.

Frequently Asked Questions (FAQ)

Q: Can DPA425PN directly replace DPA425P in existing PCB designs?

A: Yes. DPA425PN provides direct substitution. Both parts share identical package type (8-DIP), pin pitch (0.300" / 7.62mm), mounting type (through-hole), and all critical electrical specifications (input voltage 16V ~ 75V, output voltage 220V, single output). No PCB layout modifications are required.

Q: What is the primary reason for substituting DPA425P with DPA425PN?

A: DPA425P is classified as obsolete, limiting future availability and manufacturer support. DPA425PN is the active production equivalent from Power Integrations, ensuring continued supply and technical resources.

Q: Are there differences in electrical performance between DPA425P and DPA425PN?

A: No. Both parts operate identically across all specified electrical parameters: input voltage range (16V ~ 75V), output voltage (220V), operating temperature range (-40°C ~ 125°C), and output configuration (single output).

Q: Does the packaging format difference (bulk vs. tube) affect component functionality?

A: No. Packaging format affects only handling, storage, and supply chain logistics. The electronic component itself and its performance characteristics remain unchanged. DPA425PN is supplied in tube packaging, while DPA425P was supplied in bulk format.

Q: What is the significance of the RoHS compliance difference?

A: DPA425PN is RoHS Compliant, meeting restrictions on hazardous substances required by many regulatory frameworks and customer specifications. DPA425P is RoHS non-compliant. For applications subject to RoHS requirements, DPA425PN is the mandated selection.

Q: Are both parts suitable for Power Over Ethernet and Telecom applications?

A: Yes. Both DPA425P and DPA425PN are specified for identical applications: Power Over Ethernet and Telecom converter functions. Application compatibility is complete.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
