Substitute Part Grouping Explanation

Substitution eligibility for the LMV431ACM5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Reference Type: Shunt
• Output Type: Adjustable
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Tolerance: ±1%
• Mounting Type: Surface Mount
• RoHS3 Compliance

Secondary Compatibility Factors:

• Voltage - Output (Min/Fixed): 1.24V minimum
• Voltage - Output (Max): 30V or greater
• Current - Output: 15mA or greater
• Operating Temperature Range: Must support 0°C ~ 70°C minimum

Substitute parts must maintain identical package specifications and electrical classification to ensure direct PCB compatibility and functional equivalence in existing designs.

Engineering Selection Recommendations

LMV431ACM5/NOPB (Direct Equivalent)

The LMV431ACM5/NOPB is the direct equivalent manufactured by Texas Instruments with identical electrical specifications and package configuration. This part maintains Active product status, ensuring long-term availability and supply chain continuity. The NOPB designation indicates lead-free plating compliance. This substitute is recommended as the primary replacement for the Last Time Buy LMV431ACM5.

TL431AIL5T (Cross-Manufacturer Alternative)

The TL431AIL5T manufactured by STMicroelectronics provides functional substitution with enhanced electrical performance characteristics. This part maintains identical package specifications (SOT-23-5) and reference type classification. Key differences include higher maximum output voltage (36V vs. 30V), increased output current capability (100mA vs. 15mA), higher cathode current (700µA vs. 80µA), and extended operating temperature range (-40°C ~ 105°C vs. 0°C ~ 70°C). The minimum output voltage specification differs (2.495V vs. 1.24V), which may affect circuit design requirements. This substitute is suitable for applications requiring enhanced thermal performance or higher current delivery within the extended temperature range. Both parts maintain RoHS3 compliance and MSL Level 1 rating.

Frequently Asked Questions (FAQ)

Q: Can LMV431ACM5/NOPB be used as a direct replacement for LMV431ACM5?

A: Yes. The LMV431ACM5/NOPB is electrically and mechanically identical to the LMV431ACM5, with the only difference being the lead-free plating designation (NOPB). Both parts share identical electrical specifications, package configuration, and performance characteristics.

Q: Is TL431AIL5T a direct substitute for LMV431ACM5?

A: TL431AIL5T is a functional substitute with the same package type (SOT-23-5) and reference classification. However, circuit design verification is required due to differences in minimum output voltage (2.495V vs. 1.24V), output current capability (100mA vs. 15mA), and operating temperature range (-40°C ~ 105°C vs. 0°C ~ 70°C).

Q: What are the key differences between LMV431ACM5 and TL431AIL5T?

A: The primary differences are: (1) Minimum output voltage: LMV431ACM5 specifies 1.24V while TL431AIL5T specifies 2.495V; (2) Maximum output current: LMV431ACM5 supports 15mA while TL431AIL5T supports 100mA; (3) Operating temperature range: LMV431ACM5 operates 0°C ~ 70°C while TL431AIL5T operates -40°C ~ 105°C; (4) Cathode current: LMV431ACM5 draws 80µA while TL431AIL5T draws 700µA.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both LMV431ACM5/NOPB and TL431AIL5T are RoHS3 compliant with MSL Level 1 rating, meeting environmental and regulatory requirements for industrial applications.

Q: What packaging formats are available for these parts?

A: All three parts are available in SOT-23-5 surface mount package configuration. LMV431ACM5 and LMV431ACM5/NOPB are supplied in Cut Tape (CT) and Digi-Reel® formats. TL431AIL5T is supplied in Tape & Reel (TR) format.

Q: Why is LMV431ACM5 marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued this specific part number variant. The LMV431ACM5/NOPB remains in Active status and serves as the recommended long-term replacement for new designs and ongoing procurement.
