REF5030IDR Equivalent & Substitute Parts

Part Overview

The REF5030IDR is a Series Voltage Reference IC manufactured by Texas Instruments, designed for precision voltage reference applications requiring fixed 3V output. This active product operates across industrial temperature ranges (-40°C to 125°C) and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or application-specific requirements within the Power Management (PMIC) category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the REF5030IDR are qualified based on the following electrical and mechanical parameters:

Critical Compatibility Parameters:

• Output Voltage: Fixed 3V (exact match required)
• Output Current: 10 mA (exact match required)
• Package Type: 8-SOIC form factor (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• RoHS3 Compliance: Required

Allowable Variation Parameters:

• Tolerance: REF5030IDR specifies ±0.05%; substitute parts with ±0.1% or ±0.2% tolerance are acceptable for applications where tighter tolerance is not mandatory
• Temperature Coefficient: REF5030IDR specifies 3 ppm/°C; substitute parts with up to 10 ppm/°C are acceptable
• Input Voltage Range: REF5030IDR operates 3.2V ~ 18V; substitute parts with wider input ranges (5V ~ 36V) are acceptable
• Supply Current: REF5030IDR draws 1.2 mA; substitute parts drawing 1 mA are acceptable
• Packaging Format: Cut Tape (CT), Tube, or Tape & Reel (TR) formats are interchangeable based on assembly requirements
• MSL Rating: REF5030IDR is MSL 2; substitute parts with MSL 1 represent improved moisture performance

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and RoHS3 compliance, meeting regulatory requirements equivalent to the REF5030IDR. Selection between substitute options depends on application tolerance requirements and packaging logistics:

ADR06BRZ and ADR06BRZ-REEL7 provide tolerance of ±0.1% with temperature coefficient of 3 ppm/°C, matching the thermal stability of the REF5030IDR while offering improved moisture sensitivity (MSL 1). These parts are preferred when tolerance performance approaching the original specification is required.

ADR06ARZ and ADR06ARZ-REEL7 provide tolerance of ±0.2% with temperature coefficient of 10 ppm/°C. These parts are suitable for applications where relaxed tolerance specifications are acceptable and cost optimization is a consideration.

Packaging format selection (Tube, Cut Tape & Digi-Reel, or Tape & Reel) is determined by assembly process requirements and does not affect electrical performance. All substitute parts operate across the full -40°C to 125°C temperature range and accept input voltages from 5V to 36V, providing broader input compatibility than the original REF5030IDR specification of 3.2V to 18V.

Frequently Asked Questions (FAQ)

Q: Can ADR06ARZ substitute for REF5030IDR in all applications?

A: ADR06ARZ is electrically compatible for applications where ±0.2% tolerance and 10 ppm/°C temperature coefficient are acceptable. Applications requiring ±0.05% tolerance or superior temperature stability should use ADR06BRZ or ADR06BRZ-REEL7 instead.

Q: What is the difference between ADR06ARZ and ADR06ARZ-REEL7?

A: Both parts are electrically identical. ADR06ARZ is supplied in Tube packaging, while ADR06ARZ-REEL7 is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility and volume requirements.

Q: Are all substitute parts pin-compatible with REF5030IDR?

A: Yes. All substitute parts use the 8-SOIC package with identical pin configuration and spacing (0.154", 3.90mm width), enabling direct PCB footprint compatibility.

Q: What is the advantage of ADR06BRZ over ADR06ARZ?

A: ADR06BRZ provides ±0.1% tolerance and 3 ppm/°C temperature coefficient, delivering performance closer to the REF5030IDR specification. ADR06BRZ also features MSL 1 (Unlimited) moisture sensitivity versus MSL 2 (1 Year) for the original part.

Q: Can substitute parts accept the same input voltage range as REF5030IDR?

A: Substitute parts accept 5V to 36V input, which encompasses the REF5030IDR range of 3.2V to 18V. However, applications requiring operation below 5V input must use REF5030IDR or verify alternative solutions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of REF5030IDR.
