Substitute Part Grouping Explanation

Substitution of the DPA422PN is determined by strict equivalence across the following parameters:

• Input Voltage Range: 16V ~ 75V
• Output Voltage: 220V
• Number of Outputs: 1
• Package Type: 8-DIP (0.300", 7.62mm)
• Mounting Configuration: Through Hole
• Operating Temperature Range: -40°C ~ 125°C
• Manufacturer Series: DPA-Switch®

The DPA423PN meets all specified electrical and mechanical parameters, maintaining identical functional characteristics while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The DPA423PN serves as the direct functional equivalent to the obsolete DPA422PN. Both devices share identical electrical specifications, package geometry, and thermal operating range. The DPA423PN is currently in active production status, ensuring long-term availability and supply chain continuity.

The DPA423PN carries RoHS Compliance certification, providing enhanced environmental regulatory alignment compared to the DPA422PN. Both parts maintain equivalent REACH and ECCN classifications, supporting consistent export and regulatory documentation requirements.

For applications currently utilizing DPA422PN, direct substitution with DPA423PN is supported without circuit modification, provided the through-hole mounting configuration and 8-DIP package footprint remain compatible with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can DPA423PN directly replace DPA422PN in existing designs?

A: Yes. The DPA423PN is electrically and mechanically equivalent to the DPA422PN. Both devices feature identical input voltage range (16V ~ 75V), output voltage (220V), package type (8-DIP), and operating temperature range (-40°C ~ 125°C). No circuit redesign is required for substitution.

Q: What is the primary reason for substituting DPA422PN?

A: The DPA422PN is classified as obsolete. The DPA423PN is the active equivalent, ensuring continued availability and supply chain support for new production and legacy system maintenance.

Q: Are there packaging differences between these parts?

A: Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packages. The DPA423PN is supplied in Tube packaging, while the DPA422PN packaging specification was not provided. PCB footprint and mounting requirements remain unchanged.

Q: Does the DPA423PN meet environmental compliance requirements?

A: The DPA423PN is RoHS Compliant and REACH Unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, supporting consistent regulatory and export documentation.

Q: Are there inventory considerations for these parts?

A: The DPA423PN maintains higher inventory availability (7278 Pcs) compared to the DPA422PN (1900 Pcs), supporting both immediate procurement needs and long-term supply assurance.
