LMV431CM5 Equivalent & Substitute Parts

Part Overview

The LMV431CM5 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 a tolerance of ±1.5%. The device is housed in a SOT-23-5 surface mount package and operates across a temperature range of 0°C to 70°C.

The LMV431CM5 is currently classified as Last Time Buy, indicating that the manufacturer has discontinued or will discontinue production. This status necessitates identifying equivalent substitute parts to ensure design continuity and supply chain reliability for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV431CM5 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Adjustable
• Voltage - Output (Min/Fixed): 1.24V
• Voltage - Output (Max): 30V
• Current - Output: 15 mA
• Tolerance: ±1.5%
• Current - Cathode: 80 µA
• Package / Case: SC-74A, SOT-753
• Operating Temperature: 0°C ~ 70°C (TA)

Parts meeting all these specifications are classified as direct equivalents and may be used as substitutes without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The LMV431CM5/NOPB is a direct equivalent substitute for the LMV431CM5. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the LMV431CM5 is Last Time Buy, while the LMV431CM5/NOPB maintains Active status.

For new designs and ongoing production, the LMV431CM5/NOPB is the recommended selection due to its active availability and continued manufacturer support. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency.

Frequently Asked Questions (FAQ)

Q: Can LMV431CM5/NOPB be used as a direct replacement for LMV431CM5?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage output, current ratings, tolerance, and package configuration. No circuit redesign or board layout modification is required.

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

A: The "/NOPB" suffix denotes "No Plumbum" (lead-free) packaging designation. This is a manufacturer packaging variant that does not affect electrical performance or compatibility.

Q: Why is the LMV431CM5 classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or will discontinue production. Customers are advised to secure inventory or transition to active alternatives such as the LMV431CM5/NOPB.

Q: Are there any differences in RoHS or REACH compliance between these parts?

A: No. Both the LMV431CM5 and LMV431CM5/NOPB maintain identical ROHS3 compliance and REACH Unaffected status.

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

A: Yes. The identical SOT-23-5 package, pin configuration, and electrical specifications allow direct substitution without design modifications.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life and no special moisture control requirements during storage or handling.
