Substitute Part Grouping Explanation

Substitution of the REF5020AIDRG4 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Fixed output voltage: 2.048V
• Output current capability: 10 mA
• Voltage tolerance: ±0.1%
• Temperature coefficient: 8 ppm/°C
• Input voltage range: 2.7V ~ 18V
• Supply current: 1.2 mA
• Operating temperature range: -40°C ~ 125°C

Mechanical Parameters (Must Match):

• Package type: 8-SOIC
• Package dimensions: 0.154" width (3.90mm)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 compliance required
• Moisture Sensitivity Level: 2 (1 Year)

The identified substitute parts maintain identical electrical and mechanical specifications, ensuring direct functional replacement without circuit redesign. Differences in product status and packaging format do not affect electrical performance or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

REF5020AIDR: This substitute part is electrically and mechanically identical to the REF5020AIDRG4 and maintains active product status with Texas Instruments. It is available in Cut Tape (CT) and Digi-Reel® packaging formats. Selection of this part is appropriate for standard industrial and commercial applications where automotive qualification is not required.

REF5020AQDRQ1: This substitute part is electrically and mechanically identical to the REF5020AIDRG4 and is qualified to the AEC-Q100 automotive standard. The automotive-grade designation and AEC-Q100 qualification make this part suitable for automotive and mission-critical applications requiring enhanced reliability documentation and traceability. This part maintains active product status.

Both substitute parts are ROHS3 compliant and carry identical electrical performance specifications. Selection between them depends on application requirements: standard industrial use favors REF5020AIDR, while automotive or high-reliability applications favor REF5020AQDRQ1.

Frequently Asked Questions (FAQ)

Q: Can REF5020AIDR be used as a direct replacement for REF5020AIDRG4?

A: Yes. REF5020AIDR is a parametric equivalent with identical electrical specifications, output voltage, tolerance, temperature coefficient, and 8-SOIC package configuration. The primary difference is product status (active versus obsolete) and packaging format availability.

Q: What is the difference between REF5020AIDR and REF5020AQDRQ1?

A: Both parts are electrically identical with matching output voltage, tolerance, and package specifications. REF5020AQDRQ1 carries automotive-grade designation and AEC-Q100 qualification, making it suitable for automotive applications. REF5020AIDR is standard industrial grade. Selection depends on application requirements.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-SOIC package with identical pinout and electrical characteristics, ensuring direct PCB compatibility without layout modifications.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Digi-Reel, or standard tube) does not affect electrical performance or functional characteristics. Format selection is determined by manufacturing and assembly process requirements.

Q: Is REF5020AQDRQ1 suitable for non-automotive applications?

A: Yes. REF5020AQDRQ1 meets all electrical and mechanical requirements for standard applications. Automotive qualification represents an additional quality assurance level and does not restrict use in non-automotive designs.

Q: What inventory status should be considered when selecting a substitute?

A: REF5020AIDR has 24,400 units in stock, and REF5020AQDRQ1 has 35,100 units in stock. Both parts maintain active product status with established supply chains, providing long-term availability compared to the obsolete REF5020AIDRG4.
