Substitute Part Grouping Explanation
Substitute parts for the REF6141IDGKR are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are defined by the following key parameters:
- Fixed output voltage of 4.096V
- Output tolerance of ±0.05%
- Output current capability of 4 mA
- Temperature coefficient of 8 ppm/°C
- Input voltage range of 4.35V ~ 5.5V
- Supply current of 1.1 mA
- Operating temperature range of -40°C ~ 125°C
- Surface mount packaging in 8-VSSOP configuration

Engineering Selection Recommendations
Both the REF6141IDGKR and REF6141IDGKT are active production parts from Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts may be based on availability, supply chain logistics, or packaging format preferences (Tape & Reel). Both parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols. The REF6141IDGKR currently maintains higher inventory availability at 3153 pieces, while the REF6141IDGKT has 1457 pieces in stock.
Frequently Asked Questions (FAQ)
Q: Can REF6141IDGKT be used as a direct replacement for REF6141IDGKR?
A: Yes. Both parts are parametric equivalents with identical electrical characteristics, output voltage, tolerance, temperature coefficient, and operating range. The 8-VSSOP package configuration is identical, enabling direct substitution in existing circuit designs without PCB modification.
Q: What is the difference between REF6141IDGKR and REF6141IDGKT?
A: The parts are electrically and mechanically identical. The suffix designations (KR vs. KT) indicate different packaging or tape reel configurations from Texas Instruments. Both are supplied in Tape & Reel format and are suitable for automated assembly processes.
Q: Are there any compliance or certification differences between these parts?
A: No. Both parts carry identical ROHS3 compliance status, REACH unaffected designation, and Moisture Sensitivity Level 2 (1 Year) rating. They meet the same regulatory and environmental standards.
Q: What are the critical parameters for substitution in voltage reference applications?
A: The critical parameters are fixed output voltage (4.096V), output tolerance (±0.05%), temperature coefficient (8 ppm/°C), and operating temperature range (-40°C to 125°C). Any substitute must match these specifications exactly to maintain circuit performance and accuracy.
Q: Can these parts be used in high-precision analog measurement circuits?
A: Yes. The ±0.05% tolerance and 8 ppm/°C temperature coefficient support precision analog applications. The 3 µVp-p noise specification (0.1Hz to 10Hz) is suitable for low-noise reference requirements in measurement and instrumentation circuits.
Q: What is the maximum output current available from these reference ICs?
A: The maximum output current is 4 mA. Circuit designs must account for this current limitation when driving load impedances or buffering stages.
