Selection Basis:

The THS3095D maintains full electrical and mechanical compatibility with the THS3095DRG4 across all specified parameters. The substitute part carries Last Time Buy status, indicating controlled availability through Texas Instruments distribution channels. Both parts meet ROHS3 compliance requirements and carry MSL 1 moisture sensitivity rating, suitable for standard surface mount assembly processes.

The transition from THS3095DRG4 to THS3095D requires no circuit redesign, PCB layout modification, or thermal management changes. Pin configuration, electrical performance, and package footprint remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the THS3095D be used as a direct replacement for the THS3095DRG4 in existing designs?

A: Yes. The THS3095D is electrically and mechanically identical to the THS3095DRG4. All electrical parameters, package dimensions, pin configuration, and operating characteristics are equivalent. No circuit modifications are required.

Q: What is the difference between the THS3095DRG4 and THS3095D part numbers?

A: The suffix designations indicate packaging and lead finish specifications. The "RG4" suffix in THS3095DRG4 and the absence of a suffix in THS3095D represent different packaging codes from Texas Instruments. The core die and electrical performance are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the THS3095DRG4 and THS3095D carry identical RoHS3 compliance status, REACH unaffected designation, and MSL 1 moisture sensitivity rating. Both are suitable for standard surface mount assembly and reflow processes.

Q: What is the current availability status of these parts?

A: The THS3095DRG4 is obsolete. The THS3095D carries Last Time Buy status, indicating limited future availability. Procurement should prioritize the THS3095D for new production orders and inventory planning.

Q: Are the package dimensions identical between THS3095DRG4 and THS3095D?

A: Yes. Both parts use the 8-SOIC package with 0.154" width (3.90mm). PCB footprints, land patterns, and assembly processes are identical.

Q: Can the THS3095D be used in high-temperature applications?

A: Both parts operate across the -40°C to 85°C temperature range. Applications requiring operation beyond 85°C require alternative component selection outside this product family.
