Substitute Part Grouping Explanation

Substitution of the REF5020IDRG4 is determined by strict equivalence across the following critical parameters:

• Output Voltage: 2.048V (fixed)
• Voltage Tolerance: ±0.05%
• Output Current: 10 mA
• Temperature Coefficient: 3 ppm/°C
• Input Voltage Range: 2.7V ~ 18V
• Supply Current: 1.2 mA
• Operating Temperature Range: -40°C ~ 125°C
• Package / Case: 8-SOIC
• Mounting Type: Surface Mount

The REF5020IDR meets all electrical and mechanical specifications required for direct substitution. The primary distinction between the main part and its substitute is product status and packaging format, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The REF5020IDR is the direct parametric equivalent for the obsolete REF5020IDRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and physical packaging. The REF5020IDR maintains active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with ROHS3 standards and carry identical moisture sensitivity ratings. The REF5020IDR is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for production environments. Selection of the REF5020IDR eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the REF5020IDR be used as a direct replacement for the REF5020IDRG4?
