Engineering Selection Recommendations

The DSPIC30F2011-20I/SO serves as the direct functional equivalent to the obsolete DSPIC30F2011T-20I/SO. Both parts are manufactured by Microchip Technology and share identical electrical, functional, and mechanical specifications. The primary distinction is product status: the main part is classified as obsolete, while the substitute is active in production.

The substitute part maintains full compliance with ROHS3 and REACH regulatory requirements. Both devices support identical supply voltage ranges (2.5V to 5.5V) and operate across the same temperature specification (-40°C to 85°C). Pin configuration, package dimensions, and peripheral functionality are identical, enabling direct replacement in existing designs without circuit modification.

The substitute part is available in Tube packaging, providing standard component handling and storage compatibility with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can DSPIC30F2011-20I/SO directly replace DSPIC30F2011T-20I/SO in production?

A: Yes. Both parts are electrically and mechanically identical. The substitute part is active in production and maintains all functional specifications, memory configuration, I/O count, and peripheral capabilities of the obsolete part.

Q: Are there differences in pin configuration between these parts?

A: No. Both parts use the 18-SOIC package with identical pin assignments, voltage specifications, and I/O functionality. No PCB redesign is required.

Q: What is the significance of the product status difference?

A: The main part (DSPIC30F2011T-20I/SO) is classified as obsolete and is no longer manufactured. The substitute part (DSPIC30F2011-20I/SO) is active and available from Microchip Technology, ensuring long-term supply continuity for new production runs and design updates.
