REF6250IDGKR Equivalent & Substitute Parts

Part Overview

The REF6250IDGKR is a Series Voltage Reference IC manufactured by Texas Instruments, designed to provide a fixed 5V output with ±0.05% tolerance. This precision voltage reference is classified as a Power Management (PMIC) component and is currently in Active product status. The device is essential in applications requiring stable, low-noise voltage references for analog signal conditioning, data acquisition systems, and precision measurement circuits. Alternative models may be required due to inventory constraints, regional availability, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the REF6250IDGKR are identified based on strict electrical and mechanical parameter matching. The substitution criteria are defined by the following key parameters:

• Fixed 5V output voltage
• ±0.05% output tolerance
• 3 mA maximum output current
• 3ppm/°C temperature coefficient
• 3µVp-p noise specification (0.1Hz to 10Hz)
• 5.3V ~ 5.5V input voltage range
• 1.15mA supply current
• 0°C ~ 70°C operating temperature range
• 8-VSSOP surface mount package
• Active product status
• ROHS3 compliance and REACH Unaffected designation

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Packaging format (Tape & Reel) is consistent across all substitute options.

Parameter Comparison

Engineering Selection Recommendations

Both the REF6250IDGKR and REF6250IDGKT are Active status components manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on procurement availability and inventory status rather than technical performance differences. Both parts maintain ROHS3 compliance and REACH Unaffected designation, ensuring regulatory compliance across global markets. The 8-VSSOP surface mount package is consistent across both options, enabling direct board-level substitution without design modification. Supply current requirements (1.15mA) and output current capability (3 mA) are identical, supporting equivalent system integration.

Frequently Asked Questions (FAQ)

Q: Can REF6250IDGKT be used as a direct replacement for REF6250IDGKR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage (5V), tolerance (±0.05%), temperature coefficient (3ppm/°C), and 8-VSSOP package configuration. Direct substitution is supported at the board level without circuit modification.

Q: Are there differences in packaging between these substitute parts?

A: Both parts use identical 8-VSSOP surface mount packaging with 0.118" width (3.00mm). The only difference is the tape reel configuration, which does not affect component functionality or board assembly compatibility.

Q: What are the critical parameters for substitution compatibility?

A: The critical parameters are fixed 5V output voltage, ±0.05% tolerance, 3 mA output current, 3ppm/°C temperature coefficient, 5.3V ~ 5.5V input voltage range, and 8-VSSOP package format. All substitute parts must match these specifications exactly.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both REF6250IDGKR and REF6250IDGKT are ROHS3 compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the operating temperature range for these parts?

A: Both parts operate across 0°C to 70°C (TA), with a temperature coefficient of 3ppm/°C, ensuring stable voltage reference performance across this temperature range.
