REF6030IDGKR Equivalent & Substitute Parts

Part Overview

The REF6030IDGKR is a Series Voltage Reference IC manufactured by Texas Instruments, designed for precision voltage reference applications requiring fixed 3V output with ±0.05% tolerance. This component operates across a 3.25V to 5.5V input range and delivers 4 mA output current in an 8-VSSOP surface mount package. The part is currently in active production status with ROHS3 compliance and MSL Level 2 rating. Alternative part numbers may be required due to inventory availability, supply chain constraints, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the REF6030IDGKR is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part REF6030IDGKT maintains identical specifications across the following key criteria:

Reference voltage output (3V fixed), output tolerance (±0.05%), temperature coefficient (5 ppm/°C), noise characteristics (3 µVp-p at 0.1Hz to 10Hz), input voltage range (3.25V ~ 5.5V), output current capability (4 mA), supply current (1.1 mA), operating temperature range (-40°C ~ 125°C), and package configuration (8-VSSOP). Both parts are manufactured by Texas Instruments, carry active product status, and meet ROHS3 and REACH compliance requirements. The only distinction between these parts is the packaging format designation (TR suffix variation), which does not affect electrical performance or mechanical compatibility in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both REF6030IDGKR and REF6030IDGKT are functionally equivalent components suitable for direct substitution in applications requiring a 3V precision series voltage reference. Selection between these parts should be based on inventory availability and procurement lead times, as all electrical characteristics, mechanical dimensions, and regulatory compliance certifications are identical. Both parts maintain active product status from Texas Instruments and satisfy ROHS3 and REACH compliance requirements for regulated markets. The MSL Level 2 rating with 1-year floor life applies uniformly to both parts, requiring standard moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can REF6030IDGKT be used as a direct replacement for REF6030IDGKR in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. No circuit modifications or PCB layout changes are required for substitution.
