Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV431BIMF is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Reference type classification (Shunt)
• Output type configuration (Adjustable)
• Minimum and maximum output voltage range (1.24V to 30V)
• Output current capability (15mA)
• Voltage tolerance specification (±0.5%)
• Cathode current requirement (80µA)
• Operating temperature range (-40°C ~ 85°C)

Mechanical Parameters:

• Package type (SOT-23-3 / TO-236-3 / SC-59)
• Surface mount mounting type
• Pin configuration compatibility

Parts meeting all specified electrical and mechanical parameters are classified as direct equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The LMV431BIMF/NOPB is a direct electrical and mechanical equivalent to the LMV431BIMF. Both parts share identical electrical specifications across all critical parameters including reference voltage, output current, tolerance, and operating temperature range. Both components are packaged in SOT-23-3 surface mount configuration with identical pin assignments.

The primary distinction between these part numbers is product status: the LMV431BIMF is designated Last Time Buy, while the LMV431BIMF/NOPB maintains Active status. The "/NOPB" suffix indicates lead-free plating without lead-free solder coating, representing a standard manufacturing designation from Texas Instruments.

For new designs or production requiring long-term supply assurance, the LMV431BIMF/NOPB is the appropriate selection. Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the LMV431BIMF/NOPB be used as a direct replacement for the LMV431BIMF?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The LMV431BIMF/NOPB provides the same reference voltage (1.24V adjustable to 30V), output current (15mA), tolerance (±0.5%), and operating temperature range (-40°C ~ 85°C). Pin configuration and SOT-23-3 package dimensions are identical, enabling direct substitution without circuit modification.

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

A: The "/NOPB" designation indicates the part is manufactured with lead-free plating without lead-free solder coating. This is a standard Texas Instruments manufacturing designation and does not affect electrical performance or compatibility.

Q: Are there any compliance or certification differences between these part numbers?

A: No. Both the LMV431BIMF and LMV431BIMF/NOPB maintain identical RoHS3 compliance status and Moisture Sensitivity Level (MSL) classification of 1 (Unlimited). Both parts are REACH Unaffected and carry the same ECCN and HTSUS classifications.

Q: Why is the LMV431BIMF marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued this part number. The LMV431BIMF/NOPB remains in active production and serves as the current equivalent for ongoing supply requirements.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts utilize the TO-236-3 / SC-59 / SOT-23-3 package with identical physical dimensions and pin spacing, ensuring compatibility with existing PCB layouts and assembly processes.
