REF5030AIDG4 Equivalent & Substitute Parts

Part Overview

The REF5030AIDG4 is a series voltage reference IC manufactured by Texas Instruments, designed to provide a fixed 3V output with ±0.1% tolerance. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates across a wide input voltage range of 3.2V to 18V and delivers 10 mA output current, suitable for precision analog applications requiring stable voltage references.

Substitute Part Grouping Explanation

Substitution for the REF5030AIDG4 is determined by the following critical parameters: fixed 3V output voltage, 10 mA output current capability, 8-SOIC package format, surface mount mounting type, and operating temperature range of -40°C to 125°C. Substitute parts must maintain electrical compatibility across these core specifications.

Substitutes are grouped into two categories based on tolerance and temperature coefficient performance:

Group 1 (Tighter Tolerance Match): Parts maintaining ±0.1% tolerance specification, including REF5030AID (Texas Instruments, active status) and ADR06BRZ / ADR06BRZ-REEL7 (Analog Devices Inc., active status). These provide direct functional equivalence with the original part's precision characteristics.

Group 2 (Relaxed Tolerance): ADR06ARZ and ADR06ARZ-REEL7 (Analog Devices Inc., active status) with ±0.2% tolerance. These parts maintain the same output voltage and current specifications but with broader tolerance margins and extended input voltage range (5V ~ 36V).

All substitute parts share the 8-SOIC package, surface mount configuration, and -40°C to 125°C operating temperature range. Packaging variants (Tube, Cut Tape & Digi-Reel, Tape & Reel) do not affect electrical compatibility.

Engineering Selection Recommendations

Primary Recommendation: REF5030AID is the direct active equivalent, manufactured by Texas Instruments with identical electrical specifications and packaging. This part maintains the original design intent with no design modifications required.

Secondary Recommendation: ADR06BRZ and ADR06BRZ-REEL7 (Analog Devices Inc.) provide superior performance characteristics with tighter temperature coefficient (3 ppm/°C versus 8 ppm/°C), matching the ±0.1% tolerance specification. These parts feature extended input voltage range (5V ~ 36V) and improved moisture sensitivity rating (MSL 1 Unlimited versus MSL 2 1-Year). Both are actively manufactured and ROHS3 compliant.

Alternative Option: ADR06ARZ and ADR06ARZ-REEL7 are suitable for applications where ±0.2% tolerance is acceptable. These parts offer the same extended input voltage range and superior MSL rating as the ADR06B variants, with lower supply current consumption (1 mA versus 1.2 mA).

All recommended substitutes maintain ROHS3 compliance, 8-SOIC package compatibility, and -40°C to 125°C operating temperature range. Selection should be based on tolerance requirements, input voltage constraints, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can REF5030AID directly replace REF5030AIDG4 without circuit modifications?

A: Yes. REF5030AID is electrically and mechanically identical to REF5030AIDG4, with matching output voltage (3V), output current (10 mA), tolerance (±0.1%), temperature coefficient (8 ppm/°C), input voltage range (3.2V ~ 18V), and 8-SOIC package. No design changes are required.

Q: What are the key differences between Texas Instruments REF5030 and Analog Devices ADR06 series?

A: Both provide 3V fixed output at 10 mA with 8-SOIC packaging. Primary differences include: ADR06 series offers extended input voltage range (5V ~ 36V versus 3.2V ~ 18V), lower supply current (1 mA versus 1.2 mA), and improved MSL rating (1 Unlimited versus 2 1-Year). ADR06BRZ matches ±0.1% tolerance with superior temperature coefficient (3 ppm/°C). ADR06ARZ provides ±0.2% tolerance.

Q: Are packaging variants (Tube, Cut Tape & Digi-Reel, Tape & Reel) electrically equivalent?

A: Yes. Packaging variants REF5030AID, ADR06ARZ, ADR06ARZ-REEL7, ADR06BRZ, and ADR06BRZ-REEL7 are electrically identical within their respective part families. Packaging differences affect only handling, storage, and supply chain logistics, not electrical performance or pin configuration.

Q: Which substitute is recommended for high-precision applications?

A: ADR06BRZ or ADR06BRZ-REEL7 are recommended for high-precision applications. These parts maintain ±0.1% tolerance matching the original specification while providing superior temperature coefficient performance (3 ppm/°C versus 8 ppm/°C), resulting in improved long-term stability across the -40°C to 125°C operating range.

Q: Can ADR06ARZ (±0.2% tolerance) be used in place of REF5030AIDG4 (±0.1% tolerance)?

A: ADR06ARZ is electrically compatible and functionally equivalent for applications where ±0.2% tolerance is acceptable. However, if the original design requires ±0.1% tolerance, ADR06ARZ does not meet the specification. Verify tolerance requirements before substitution.

Q: What is the impact of different input voltage ranges on circuit design?

A: REF5030AIDG4 requires input voltage between 3.2V and 18V. ADR06 series parts accept 5V to 36V input. If your circuit operates below 5V input, REF5030AID must be used. If input voltage exceeds 18V, ADR06 series parts are required. Verify input voltage constraints in your application before selecting a substitute.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. REF5030AID, ADR06ARZ, ADR06ARZ-REEL7, ADR06BRZ, and ADR06BRZ-REEL7 are all ROHS3 compliant and REACH unaffected, matching the original REF5030AIDG4 compliance status.
