REF5020IDGKT Equivalent & Substitute Parts

Part Overview

The REF5020IDGKT is a series voltage reference integrated circuit manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device provides a fixed 2.048V output with ±0.05% tolerance and is designed for precision analog applications requiring stable reference voltages. The part is currently in active production status with 73,851 units available in new original inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, procurement lead times, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the REF5020IDGKT is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.048V
• Output current capability of 10 mA
• Tolerance specification of ±0.05%
• Temperature coefficient of 3 ppm/°C
• Input voltage range of 2.7V ~ 18V
• Supply current of 1.2 mA
• Operating temperature range of -40°C ~ 125°C
• Surface mount package configuration (8-TSSOP, 8-MSOP)
• Compliance certifications (ROHS3, REACH Unaffected)

The REF5020IDGKR is identified as a parametric equivalent based on identical electrical specifications and mechanical compatibility. Both parts share the same base product number (REF5020) and are manufactured by Texas Instruments with equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both REF5020IDGKT and REF5020IDGKR are active production parts manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability and procurement lead times
• Packaging format requirements (Tape & Reel vs. alternative packaging)
• Supply chain logistics and regional distribution
• Compliance requirements (both meet ROHS3 and REACH standards)

The REF5020IDGKT is currently available with higher inventory (73,851 units) compared to REF5020IDGKR (1,729 units). Both parts maintain equivalent performance in precision voltage reference applications and are suitable for direct substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can REF5020IDGKR be used as a direct replacement for REF5020IDGKT?

A: Yes. Both parts are parametric equivalents with identical output voltage (2.048V), tolerance (±0.05%), temperature coefficient (3 ppm/°C), and package configuration (8-TSSOP, 8-MSOP). They are electrically and mechanically interchangeable.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching output voltage, output current, tolerance, temperature coefficient, input voltage range, supply current, operating temperature range, package type, and compliance certifications. All these parameters must be identical between the main part and substitute.

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

A: Both parts use the same surface mount package configuration (8-TSSOP, 8-MSOP with 0.118" width, 3.00mm). The primary packaging difference is the delivery format (Tape & Reel for REF5020IDGKT vs. unspecified for REF5020IDGKR), which does not affect circuit-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both REF5020IDGKT and REF5020IDGKR are ROHS3 compliant and REACH unaffected, with identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year).

Q: What is the difference between these part numbers?

A: The part numbers differ only in their suffix designation (IDGKT vs. IDGKR). Both share the same base product number (REF5020) and are manufactured by Texas Instruments with equivalent performance characteristics. The suffix typically indicates packaging or distribution format variations.
