Substitute Part Grouping Explanation

Substitution of the TPS60303DGS is determined by strict equivalence across the following critical parameters:

  • Input voltage range: 0.9V to 1.8V
  • Output voltage configuration: Fixed dual outputs at 2Vin and 3V
  • Output current capability: 40mA and 20mA per channel
  • Switching frequency: 700kHz
  • Topology: Charge pump architecture
  • Package: 10-TFSOP / 10-MSOP form factor
  • Operating temperature range: -40°C to 125°C
  • Regulatory compliance: ROHS3, REACH Unaffected

The TPS60303DGSR is identified as a manufacturer-recommended substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format (Tape & Reel versus bulk) and product lifecycle status.

Engineering Selection Recommendations

The TPS60303DGSR is the manufacturer-recommended substitute for the TPS60303DGS. Both parts share identical electrical and mechanical specifications, ensuring direct functional compatibility in circuit applications. The TPS60303DGS is classified as Obsolete, while the TPS60303DGSR carries Last Time Buy status, indicating limited future availability.

Selection between these parts should be based on:

  • Packaging requirements: The TPS60303DGS is supplied in bulk format, while the TPS60303DGSR is supplied in Tape & Reel format for automated assembly processes.
  • Supply chain availability: The TPS60303DGSR offers 904 units in current inventory compared to 2200 units of the TPS60303DGS.
  • Production timeline: For new designs or long-term production, the TPS60303DGSR is the preferred choice due to its Last Time Buy status providing extended availability window.

Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can the TPS60303DGSR directly replace the TPS60303DGS in existing designs?

A: Yes. The TPS60303DGSR is electrically and mechanically identical to the TPS60303DGS. Pin configuration, electrical performance, and thermal characteristics are equivalent. No circuit modifications are required.

Q: What is the difference between TPS60303DGS and TPS60303DGSR?

A: The primary difference is packaging format. The TPS60303DGS is supplied in bulk packaging, while the TPS60303DGSR is supplied in Tape & Reel format. Both parts are identical in electrical specifications, output voltage, current ratings, switching frequency, and operating temperature range.

Q: Why is the TPS60303DGS marked as Obsolete?

A: The Obsolete status indicates that Texas Instruments has discontinued active production of this part number. The TPS60303DGSR, with Last Time Buy status, represents the final production run and should be considered for future procurement.

Q: Are there any compatibility concerns with the 10-TFSOP / 10-MSOP package?

A: No. Both substitute parts use the identical 10-TFSOP / 10-MSOP package with 0.118" width (3.00mm). PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: What output voltages does this charge pump regulator provide?

A: The TPS60303DGS and TPS60303DGSR provide two fixed output voltages: 2Vin (twice the input voltage) and 3V. Output currents are 40mA and 20mA respectively.

Q: What is the input voltage range for these devices?

A: Both parts operate with input voltages between 0.9V and 1.8V, making them suitable for single-cell battery applications and low-voltage power sources.
