Substitute Part Grouping Explanation

Substitute parts for the REF6125IDGKR are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criterion is the maintenance of all core electrical specifications: fixed 2.5V output, ±0.05% tolerance, 4 mA output current, 8ppm/°C temperature coefficient, 3µVp-p noise performance, 3V to 5.5V input voltage range, and 1.1mA supply current. The device must operate across the full industrial temperature range of -40°C to 125°C and maintain the same 8-VSSOP package footprint with 8-TSSOP/8-MSOP mechanical compatibility.

The REF6125IDGKR is supplied in Cut Tape (CT) & Digi-Reel® packaging format. Substitute parts meeting identical electrical specifications but supplied in alternative packaging formats (such as Tape & Reel) are classified as parametric equivalents. Both the main part and substitute maintain active product status, ROHS3 compliance, and MSL 2 rating, ensuring compatibility in standard manufacturing and assembly processes.

Engineering Selection Recommendations

Both the REF6125IDGKR and REF6125IDGKT are active products from Texas Instruments with identical electrical specifications and mechanical compatibility. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

The REF6125IDGKR in Cut Tape (CT) & Digi-Reel® format is suitable for applications requiring smaller order quantities or mixed component sourcing. The REF6125IDGKT in Tape & Reel (TR) format is appropriate for high-volume production environments where continuous reel feeding into automated assembly equipment is standard practice.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across global manufacturing standards. The MSL 2 rating (1 Year) applies to both variants, requiring standard moisture control during storage and handling. No functional or performance differences exist between these parts; selection is based on supply chain logistics and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can REF6125IDGKT be used as a direct replacement for REF6125IDGKR in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format (Cut Tape vs. Tape & Reel). Circuit performance, pin configuration, and electrical specifications are identical.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies components on carrier tape in cut lengths, suitable for manual assembly or small-batch operations. Tape & Reel packaging supplies components on continuous reels, optimized for automated pick-and-place assembly in high-volume manufacturing. Both formats contain the same component in the same 8-VSSOP package.

Q: Are there any compatibility issues when switching between REF6125IDGKR and REF6125IDGKT?

A: No compatibility issues exist. Both parts share identical electrical specifications, operating temperature range, supply voltage requirements, output voltage, tolerance, and thermal characteristics. The 8-VSSOP package footprint is identical for both variants.

Q: What does the ±0.05% tolerance specification mean for these parts?

A: The ±0.05% tolerance indicates the maximum deviation of the 2.5V output voltage from the nominal value across the specified operating conditions. This represents a precision voltage reference suitable for applications requiring high accuracy.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both REF6125IDGKR and REF6125IDGKT operate across the full industrial temperature range of -40°C to 125°C with a temperature coefficient of 8ppm/°C, ensuring stable performance across extended temperature variations.

Q: What is the MSL 2 rating and how does it affect handling?

A: MSL 2 (Moisture Sensitivity Level 2) indicates the component requires standard moisture control during storage and handling, with a 1-year shelf life under controlled conditions. Both parts carry this identical rating and require equivalent moisture management procedures.
