REF6041IDGKR Equivalent & Substitute Parts

Part Overview

The REF6041IDGKR is a Series Voltage Reference IC manufactured by Texas Instruments, designed for precision analog applications requiring stable fixed voltage outputs. This component generates a fixed 4.096V reference with ±0.05% tolerance and operates across industrial temperature ranges (-40°C to 125°C). The device is actively produced and widely used in data acquisition systems, instrumentation, and precision measurement circuits where accurate voltage references are critical. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across different packaging or distribution formats.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the REF6041IDGKR are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

• Voltage Output: Must be fixed at 4.096V
• Output Tolerance: Must maintain ±0.05% accuracy
• Temperature Coefficient: Must be 5ppm/°C
• Output Current Capability: Must be 4 mA
• Supply Current: Must be 1.1mA
• Input Voltage Range: Must be 4.35V ~ 5.5V
• Operating Temperature Range: Must be -40°C ~ 125°C
• Package Type: Must be 8-VSSOP (8-TSSOP, 8-MSOP equivalent)
• Mounting Type: Must be Surface Mount
• Compliance: Must maintain ROHS3 and REACH compliance

The REF6041IDGKT is classified as a parametric equivalent because it maintains identical electrical specifications and mechanical compatibility. The only difference is the packaging format (Tape & Reel distribution versus standard packaging), which does not affect circuit performance or board-level integration.

Parameter Comparison

Engineering Selection Recommendations

Both the REF6041IDGKR and REF6041IDGKT are active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and supply chain requirements:

• REF6041IDGKR: Standard packaging format, suitable for general component procurement and lower-volume applications.
• REF6041IDGKT: Tape & Reel packaging format, optimized for high-volume automated assembly and pick-and-place manufacturing processes.

Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The Moisture Sensitivity Level (MSL) rating of 2 with 1-year shelf life applies to both variants, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can REF6041IDGKT be used as a direct replacement for REF6041IDGKR?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the distribution packaging format (Tape & Reel versus standard packaging). Circuit performance, pinout, and electrical characteristics are identical.

Q: What is the difference between the packaging formats?

A: REF6041IDGKR uses standard packaging suitable for manual or small-batch assembly. REF6041IDGKT uses Tape & Reel (TR) format, which is optimized for automated pick-and-place equipment and high-volume manufacturing. The actual component and its performance are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Moisture Sensitivity Level (MSL) rating of 2 applies to both variants.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts have an MSL rating of 2 with a 1-year shelf life. This means the components must be stored in controlled humidity environments and used within one year of the manufacturing date to maintain reliability.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical electrical specifications, pinout, and package dimensions (8-VSSOP, 8-TSSOP, 8-MSOP) ensure direct compatibility. No circuit modifications or re-qualification are required when switching between these parts.

Q: What applications are these voltage reference ICs suitable for?

A: These parts are designed for precision analog applications including data acquisition systems, instrumentation, precision measurement circuits, and any application requiring a stable 4.096V reference with ±0.05% accuracy across industrial temperature ranges.
