LMV431IM5 Equivalent & Substitute Parts

Part Overview

The LMV431IM5 is a shunt voltage reference IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This adjustable reference provides a fixed output of 1.24V with a maximum output capability of 30V and supports a 15mA output current. The device is packaged in SOT-23-5 (SC-74A) surface mount configuration.

The LMV431IM5 carries a Last Time Buy product status, indicating discontinued production. This status necessitates identification of equivalent substitute parts to ensure design continuity and procurement availability for new production runs and ongoing support of existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMV431IM5 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt voltage reference architecture
• Output Type: Adjustable output configuration
• Voltage Output Range: Minimum 1.24V fixed, maximum 30V
• Output Current Capability: 15mA
• Tolerance Specification: ±1.5%
• Cathode Current: 80µA
• Operating Temperature Range: -40°C to 85°C
• Package Configuration: SOT-23-5 (SC-74A, SOT-753) surface mount
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

Substitute parts must match all electrical specifications and physical packaging requirements to ensure direct functional and mechanical compatibility without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The LMV431IM5/NOPB is a direct electrical and mechanical equivalent to the LMV431IM5. Both parts share identical electrical specifications across all critical parameters: shunt reference architecture, adjustable output configuration, 1.24V to 30V output range, 15mA output current, ±1.5% tolerance, and 80µA cathode current.

The primary distinction between these parts is product status and packaging format. The LMV431IM5 carries Last Time Buy status, indicating end-of-life production. The LMV431IM5/NOPB maintains Active product status with higher inventory availability (45,100 pieces versus 2,912 pieces), ensuring long-term procurement reliability.

Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL Level 1 (Unlimited). The packaging difference—Tape & Reel versus Cut Tape with Digi-Reel—does not affect electrical performance or circuit compatibility.

For new designs and ongoing production, the LMV431IM5/NOPB is the recommended selection due to active product status and superior supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can LMV431IM5/NOPB replace LMV431IM5 in existing designs?

A: Yes. The LMV431IM5/NOPB is electrically and mechanically identical to the LMV431IM5. All electrical parameters, operating temperature range, and SOT-23-5 package configuration are equivalent. No circuit modifications are required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) and Cut Tape (CT) are distribution formats that do not affect component electrical performance or functionality. Tape & Reel is supplied on continuous carrier tape for automated assembly. Cut Tape is supplied in shorter tape segments. Both formats contain identical components suitable for surface mount assembly.

Q: Why is the LMV431IM5 marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number variant. The LMV431IM5/NOPB remains in active production and is the recommended alternative for procurement and new designs.

Q: Are there compliance differences between these parts?

A: No. Both the LMV431IM5 and LMV431IM5/NOPB maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited).

Q: What does the /NOPB suffix indicate?

A: The /NOPB suffix indicates "No Plumbum" (lead-free) packaging, confirming ROHS3 compliance. This is a standard Texas Instruments designation for lead-free component variants.
