LMV431BCM5 Equivalent & Substitute Parts

Part Overview

The LMV431BCM5 is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision voltage regulation applications. This adjustable reference provides a fixed output of 1.24V with a maximum output capability of 30V and supports a maximum cathode current of 80µA. The device is packaged in SOT-23-5 (SC-74A) surface mount configuration.

The LMV431BCM5 carries an obsolete product status. Locating equivalent or substitute components is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements.

Substitute Part Grouping Explanation

Substitution of the LMV431BCM5 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt voltage reference
• Output Type: Adjustable
• Voltage - Output (Min/Fixed): 1.24V
• Voltage - Output (Max): 30V
• Current - Output: 15mA
• Current - Cathode: 80µA
• Tolerance: ±0.5%
• Operating Temperature Range: 0°C ~ 70°C (TA)
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Mounting Type: Surface Mount

The LMV431BCM5/NOPB is a direct manufacturer equivalent that maintains identical electrical specifications and physical packaging. The primary distinction is product status and compliance certification, with the /NOPB variant carrying active product status and RoHS3 compliance.

Engineering Selection Recommendations

The LMV431BCM5/NOPB is the direct equivalent substitute for the obsolete LMV431BCM5. Both components share identical electrical characteristics and physical packaging specifications, ensuring drop-in compatibility at the circuit level.

Selection between these variants should be based on:

• Product Status: The LMV431BCM5/NOPB carries active product status, ensuring continued manufacturer support and availability. The original LMV431BCM5 is obsolete and subject to supply discontinuation.
• Compliance Requirements: The LMV431BCM5/NOPB meets RoHS3 compliance standards, whereas the LMV431BCM5 is RoHS non-compliant. Applications requiring regulatory compliance should specify the /NOPB variant.
• Packaging Format: The LMV431BCM5/NOPB is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original variant is supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the LMV431BCM5/NOPB be used as a direct replacement for the LMV431BCM5?

A: Yes. The LMV431BCM5/NOPB is electrically and mechanically identical to the LMV431BCM5. Both components feature the same shunt voltage reference topology, output voltage range (1.24V to 30V), current ratings (15mA output, 80µA cathode), tolerance (±0.5%), operating temperature range (0°C to 70°C), and SOT-23-5 package configuration. No circuit modifications are required for substitution.

Q: What is the difference between LMV431BCM5 and LMV431BCM5/NOPB?

A: The primary differences are product status, compliance certification, and packaging format. The LMV431BCM5/NOPB is an active product with RoHS3 compliance and Tape & Reel packaging, while the original LMV431BCM5 is obsolete, RoHS non-compliant, and supplied in bulk format. Electrical and physical specifications are identical.

Q: Why is the LMV431BCM5 marked as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this specific part number variant. The LMV431BCM5/NOPB represents the current production equivalent and should be specified for new designs and ongoing procurement.

Q: Are there any compatibility concerns when switching from LMV431BCM5 to LMV431BCM5/NOPB?

A: No compatibility concerns exist. Both variants are pin-for-pin and functionally equivalent. PCB layout, schematic connections, and circuit operation remain unchanged. The substitution is transparent at the system level.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix designates "No Plumbum" (lead-free) packaging, indicating compliance with RoHS3 lead-free requirements. This variant is suitable for applications requiring environmental and regulatory compliance with modern electronics manufacturing standards.

Q: Is the SOT-23-5 package suitable for automated assembly?

A: Yes. The SOT-23-5 package is a standard surface mount configuration widely supported by automated pick-and-place and reflow soldering equipment. The LMV431BCM5/NOPB in Tape & Reel format is optimized for high-volume automated assembly processes.
