Key Parameters

Substitute Part Grouping Explanation

Substitution of the REF5020AIDG4 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 ±0.1%
• Temperature coefficient of 8 ppm/°C
• Input voltage range of 2.7V ~ 18V
• 8-SOIC surface mount package configuration
• Operating temperature range of -40°C ~ 125°C

The REF5020AID meets all these requirements and is the direct equivalent. The primary distinction between the obsolete REF5020AIDG4 and the active REF5020AID is product status and packaging format (tube vs. alternative packaging), with no electrical or functional differences.

Parameter Comparison

Engineering Selection Recommendations

The REF5020AID is the active equivalent for the obsolete REF5020AIDG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and package configurations. The REF5020AID maintains full ROHS3 compliance and equivalent moisture sensitivity ratings.

For new designs or component replacement in existing applications, the REF5020AID is the appropriate selection. The transition from REF5020AIDG4 to REF5020AID involves no functional or electrical changes, ensuring direct compatibility in circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can REF5020AID be used as a direct replacement for REF5020AIDG4?

A: Yes. The REF5020AID is electrically and functionally identical to the REF5020AIDG4. All electrical parameters, output specifications, and performance characteristics are equivalent. The primary difference is product status: REF5020AIDG4 is obsolete while REF5020AID is active.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the 8-SOIC surface mount package with identical dimensions (0.154" width, 3.90mm). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the product status difference?

A: The obsolete status of REF5020AIDG4 indicates it is no longer manufactured or supported by Texas Instruments. The REF5020AID, being active, is currently produced and available through authorized distributors, ensuring long-term supply chain reliability.

Q: Do compliance certifications differ between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH status, and MSL ratings. Regulatory and environmental compliance requirements are fully satisfied by either part.

Q: Is there a difference in output voltage accuracy or temperature stability?

A: No. Both parts deliver identical tolerance specifications (±0.1%) and temperature coefficient performance (8 ppm/°C), ensuring equivalent precision in voltage reference applications.
