Substitute Part Grouping Explanation

Substitution of the LM4030AMFX-2.5/NOPB is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Voltage: 2.5V fixed
• Output Current: 30 mA
• Tolerance: ±0.05%
• Temperature Coefficient: 20ppm/°C
• Noise Performance: 105µVp-p (0.1Hz to 10Hz)
• Cathode Current: 120 µA
• Operating Temperature Range: -40°C to 125°C
• Package Type: SOT-23-5 (SC-74A, SOT-753)
• Compliance: RoHS3, REACH Unaffected

The primary distinction between the main part and its substitute lies in packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) & Digi-Reel® format. Both formats contain identical die and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the LM4030AMFX-2.5/NOPB and LM4030AMF-2.5/NOPB are Active product status components manufactured by Texas Instruments. Selection between these parts is based on procurement and assembly requirements rather than electrical performance, as all specifications are identical.

The LM4030AMFX-2.5/NOPB in Tape & Reel format is suitable for high-volume automated assembly operations. The LM4030AMF-2.5/NOPB in Cut Tape & Digi-Reel® format accommodates lower-volume production runs, prototyping, and applications requiring smaller quantity procurement.

Both parts maintain RoHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. Moisture Sensitivity Level 1 (Unlimited) indicates no special storage or handling precautions are required.

Frequently Asked Questions (FAQ)

Q: Are the LM4030AMFX-2.5/NOPB and LM4030AMF-2.5/NOPB electrically identical?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, including 2.5V fixed output, 30 mA current capacity, ±0.05% tolerance, 20ppm/°C temperature coefficient, and 105µVp-p noise performance across the -40°C to 125°C operating range.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The LM4030AMFX-2.5/NOPB is supplied in Tape & Reel (TR) format for high-volume automated assembly. The LM4030AMF-2.5/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format for lower-volume and prototyping applications.

Q: Can I use LM4030AMF-2.5/NOPB as a direct replacement for LM4030AMFX-2.5/NOPB in my design?

A: Yes, provided your assembly process can accommodate Cut Tape & Digi-Reel® packaging. The SOT-23-5 package footprint and all electrical characteristics are identical, enabling direct schematic and PCB layout substitution.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are RoHS3 compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings. Regulatory status is equivalent.

Q: Which part should I specify for my application?

A: Specify LM4030AMFX-2.5/NOPB for high-volume production with automated tape-fed assembly equipment. Specify LM4030AMF-2.5/NOPB for prototyping, low-volume production, or when procurement flexibility is prioritized over assembly automation.
