REF6241IDGKR Equivalent & Substitute Parts

Part Overview

The REF6241IDGKR is a Series Voltage Reference IC manufactured by Texas Instruments, designed for precision analog applications requiring stable fixed voltage outputs. This Active product delivers a fixed 4.096V output with ±0.05% tolerance and operates across the 0°C to 70°C temperature range. The device is housed in an 8-VSSOP surface mount package and is ROHS3 compliant with MSL 2 rating.

Identifying equivalent and substitute parts is essential for supply chain continuity, inventory optimization, and design flexibility when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the REF6241IDGKR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 4.096V
• Output tolerance of ±0.05%
• Temperature coefficient of 3ppm/°C
• Output current capability of 4 mA
• Input voltage range of 4.35V ~ 5.5V
• Supply current of 1.1mA
• Operating temperature range of 0°C ~ 70°C
• 8-VSSOP package configuration
• Series reference type with fixed output topology

The REF6241IDGKT meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package form factor, and compliance certifications, making them directly interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both the REF6241IDGKR and REF6241IDGKT are Active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements rather than technical differentiation.

The REF6241IDGKT is a direct parametric equivalent suitable for applications where the REF6241IDGKR is specified. Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for industrial and commercial applications. The identical MSL 2 rating and operating temperature range support deployment in standard manufacturing environments without additional handling requirements.

Frequently Asked Questions (FAQ)

Q: Can REF6241IDGKT be used as a direct replacement for REF6241IDGKR?

A: Yes. The REF6241IDGKT is a parametric equivalent with identical electrical specifications, output voltage, tolerance, temperature coefficient, and package configuration. No circuit modifications are required.

Q: Are there differences in the 8-VSSOP package between these parts?

A: No. Both parts use the identical 8-VSSOP package with 0.118" width (3.00mm). PCB footprints and assembly processes are interchangeable.

Q: What determines substitution eligibility for the REF6241IDGKR?

A: Substitution is determined by matching the fixed 4.096V output voltage, ±0.05% tolerance, 3ppm/°C temperature coefficient, 4 mA output current, 4.35V ~ 5.5V input range, and 8-VSSOP package form factor. All these parameters must align for direct substitution.

Q: Do both parts have the same compliance certifications?

A: Yes. Both REF6241IDGKR and REF6241IDGKT are ROHS3 compliant, REACH Unaffected, and carry MSL 2 rating with 1-year shelf life under controlled conditions.

Q: Is there a performance difference between the two part numbers?

A: No. Both parts deliver identical performance across all specified electrical parameters including output noise (3µVp-p at 0.1Hz to 10Hz), supply current (1.1mA), and operating temperature range (0°C ~ 70°C).
