ADR5040WARTZ-R7 Equivalent & Substitute Parts

Part Overview

The ADR5040WARTZ-R7 is a shunt voltage reference integrated circuit manufactured by Analog Devices Inc., designed for precision power management applications. This Surface Mount Device (SMD) delivers a fixed 2.048V output with ±0.2% tolerance and operates across the industrial temperature range of -40°C to 125°C. The component is classified as active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part number experiences supply constraints, packaging format changes, or when alternative tape and reel configurations are required for production environments. The ADR5040WARTZ-R7 is supplied in Tape & Reel (TR) format; equivalent alternatives exist in different packaging configurations while maintaining identical electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADR5040WARTZ-R7 is determined by strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Electrical Parameters (Non-Negotiable):

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output: 2.048V
• Current - Output: 15 mA
• Tolerance: ±0.2%
• Temperature Coefficient: 100 ppm/°C
• Noise specifications: 2.8µVrms (0.1Hz to 10Hz) and 120µVrms (10Hz to 10kHz)
• Current - Cathode: 60 µA
• Operating Temperature Range: -40°C to 125°C

Mechanical Parameters (Non-Negotiable):

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• Supplier Device Package: SOT-23-3

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Packaging format variations (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect electrical substitution eligibility. Product status transitions from Active to Discontinued do not disqualify a part as a functional equivalent, provided all electrical and mechanical specifications remain identical.

Engineering Selection Recommendations

ADR5040ARTZ-R2 (Discontinued)

The ADR5040ARTZ-R2 is a parametric equivalent to the ADR5040WARTZ-R7, with all electrical specifications and mechanical dimensions matching exactly. However, this part number is discontinued at DiGi Electronics and should be selected only when existing inventory is available and supply continuity is not a concern. The part maintains REACH Unaffected status and MSL 1 rating. Selection of this part is appropriate for legacy system maintenance or when existing stock is confirmed available through alternative distribution channels.

ADR5040ARTZ-REEL7 (Active, Recommended)

The ADR5040ARTZ-REEL7 is the primary recommended substitute for the ADR5040WARTZ-R7. This part maintains active product status with confirmed high inventory availability (108,981 pieces in stock). All electrical parameters, mechanical specifications, and compliance certifications are identical to the main part number. The only difference is the packaging format: ADR5040ARTZ-REEL7 is supplied in Cut Tape (CT) & Digi-Reel® format, while ADR5040WARTZ-R7 is supplied in standard Tape & Reel (TR) format. Both formats are compatible with automated pick-and-place assembly equipment. RoHS3 compliance and unlimited moisture sensitivity rating are maintained.

Selection of ADR5040ARTZ-REEL7 is recommended for new designs, production restarts, and applications requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can ADR5040ARTZ-REEL7 be used as a direct replacement for ADR5040WARTZ-R7 in production assembly?

A: Yes. Both parts are electrically and mechanically identical. The difference in packaging format (Cut Tape & Digi-Reel® versus standard Tape & Reel) does not affect circuit performance or PCB assembly compatibility. Both formats are compatible with standard surface mount assembly equipment.

Q: What is the difference between Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is the standard continuous reel format for high-volume production. Cut Tape & Digi-Reel® is a hybrid format where components are supplied on cut tape segments loaded into a Digi-Reel carrier. Both formats deliver components in the same SOT-23-3 package with identical lead spacing and soldering characteristics. The choice between formats depends on production volume and equipment compatibility.

Q: Is ADR5040ARTZ-R2 suitable for new product designs?

A: No. ADR5040ARTZ-R2 is discontinued at DiGi Electronics and should not be selected for new designs. Use ADR5040ARTZ-REEL7 for all new applications to ensure long-term supply availability and production continuity.

Q: Are all three part numbers RoHS3 compliant?

A: ADR5040WARTZ-R7 and ADR5040ARTZ-REEL7 are explicitly RoHS3 compliant. ADR5040ARTZ-R2 compliance status is not specified in available documentation. For applications requiring verified RoHS3 compliance, select either ADR5040WARTZ-R7 or ADR5040ARTZ-REEL7.

Q: Do all substitute parts maintain the same electrical performance specifications?

A: Yes. All three part numbers deliver identical electrical performance: 2.048V fixed output, ±0.2% tolerance, 100 ppm/°C temperature coefficient, 15 mA output current, and identical noise specifications across all frequency bands. Operating temperature range, cathode current, and all other electrical parameters are identical.

Q: What is the moisture sensitivity level for these components?

A: All three part numbers carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: Can these parts be used interchangeably in existing circuit designs?

A: Yes. All three part numbers are pin-compatible and electrically equivalent. No circuit modifications are required when substituting between these part numbers. PCB layout and schematic connections remain unchanged.
