Substitute Part Grouping Explanation

Substitution of the ADR395BUJZ-R2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Output Voltage: Must be fixed at 5V
• Output Current: Must be 5 mA
• Tolerance: Must be ±0.1%
• Temperature Coefficient: Must be 9 ppm/°C
• Noise Specification (0.1Hz to 10Hz): Must be 8 µVp-p
• Input Voltage Range: Must be 5.3V ~ 15V
• Supply Current: Must be 140 µA
• Operating Temperature Range: Must be -40°C ~ 125°C
• Package / Case: Must be SOT-23-5 Thin (TSOT-23-5)
• Mounting Type: Must be Surface Mount

The ADR395BUJZ-REEL7 meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is the packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The ADR395BUJZ-REEL7 is the direct parametric equivalent for the discontinued ADR395BUJZ-R2. Both parts are manufactured by Analog Devices Inc. and share identical electrical specifications and package geometry.

Product Status Consideration: The ADR395BUJZ-R2 is discontinued at DiGi Electronics, while the ADR395BUJZ-REEL7 maintains active product status, ensuring continued availability and supply chain reliability.

Compliance and Certifications: The ADR395BUJZ-REEL7 carries ROHS3 compliance certification, providing additional regulatory assurance for applications subject to environmental standards. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging and Procurement: The primary difference lies in packaging format. The ADR395BUJZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel® format, whereas the main part uses standard Tape & Reel (TR) packaging. This distinction affects procurement quantities and handling but does not impact electrical performance or mechanical compatibility on the PCB.

Frequently Asked Questions (FAQ)

Q: Can the ADR395BUJZ-REEL7 be used as a direct replacement for the ADR395BUJZ-R2?

A: Yes. Both parts are parametrically identical across all electrical specifications, output voltage, tolerance, temperature coefficient, noise characteristics, and operating range. The SOT-23-5 package geometry is identical, ensuring mechanical compatibility on existing PCB layouts.

Q: What is the difference between the packaging formats?

A: The ADR395BUJZ-R2 uses standard Tape & Reel (TR) packaging, while the ADR395BUJZ-REEL7 uses Cut Tape (CT) & Digi-Reel® format. Both formats contain the same component; the difference is in the delivery and handling method. Cut Tape format is suitable for lower-volume applications, while Digi-Reel® provides organized reel packaging for automated assembly.

Q: Why is the ADR395BUJZ-R2 discontinued?

A: Product discontinuation is a manufacturer decision typically driven by market demand, product line consolidation, or transition to newer product families. The ADR395BUJZ-REEL7 remains in active production and serves the same functional requirements.

Q: Are there any compliance differences between the two parts?

A: The ADR395BUJZ-REEL7 explicitly carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status and EAR99 export classification. For applications requiring specific environmental compliance, the ROHS3 certification of the substitute part provides additional regulatory documentation.

Q: Will the substitute part work in my existing design without modification?

A: Yes. The ADR395BUJZ-REEL7 is electrically and mechanically equivalent to the ADR395BUJZ-R2. No circuit modifications, PCB layout changes, or firmware updates are required. The component can be substituted directly in production and assembly processes.

Q: What is the inventory status of the substitute part?

A: The ADR395BUJZ-REEL7 has 6,689 pieces in new original stock, providing reliable availability for procurement planning and production scheduling.
