TLV431ACLP Equivalent & Substitute Parts

Part Overview

The TLV431ACLP is a shunt voltage reference IC with adjustable output, manufactured by Texas Instruments. This component functions as a precision voltage reference in power management applications, offering a fixed minimum output of 1.24V with adjustable maximum output up to 6V at ±1% tolerance. The part is designated as Last Time Buy, indicating it is no longer in active production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and long-term support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV431ACLP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Reference type must be Shunt
• Output type must be Adjustable
• Minimum output voltage: 1.24V (fixed)
• Maximum output voltage: must support at least 6V
• Output current: 15 mA
• Tolerance: ±1%
• Cathode current: 80 µA

Mechanical Compatibility Criteria:

• Mounting type and package configuration must be compatible with the application circuit design

The substitute parts identified maintain electrical equivalence across all specified parameters while offering different packaging options and improved product status (Active vs. Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

TLV431AIDBZR is the primary substitute for through-hole to surface-mount migration. This part maintains identical electrical specifications (1.24V to 6V adjustable output, 15 mA, ±1% tolerance, 80 µA cathode current) while offering Active product status and extended operating temperature range (-40°C to 85°C). The SOT-23-3 package provides a compact surface-mount alternative to the TO-92-3 through-hole configuration. This part is recommended when PCB redesign to surface-mount technology is feasible.

LMV431AIM5/NOPB is an alternative substitute with extended maximum output voltage capability (30V vs. 6V). This part maintains all core electrical parameters (1.24V minimum, 15 mA output, ±1% tolerance, 80 µA cathode current) and offers Active product status with extended operating temperature range (-40°C to 85°C). The SOT-23-5 package accommodates additional pins for enhanced functionality. This part is suitable when higher output voltage capability is required or when SOT-23-5 package compatibility exists in the design.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can TLV431AIDBZR directly replace TLV431ACLP in existing through-hole designs?

A: TLV431AIDBZR maintains full electrical equivalence but requires PCB redesign due to package change from TO-92-3 (through-hole) to SOT-23-3 (surface-mount). The electrical specifications are identical: 1.24V to 6V adjustable output, 15 mA output current, ±1% tolerance, and 80 µA cathode current.

Q: What is the key difference between TLV431AIDBZR and LMV431AIM5/NOPB?

A: The primary electrical difference is maximum output voltage: TLV431AIDBZR supports 6V maximum, while LMV431AIM5/NOPB supports 30V maximum. Both maintain the 1.24V minimum output, 15 mA output current, and ±1% tolerance. Package configuration also differs: SOT-23-3 versus SOT-23-5.

Q: Are all substitute parts RoHS compliant?

A: Yes. TLV431ACLP, TLV431AIDBZR, and LMV431AIM5/NOPB are all ROHS3 Compliant and REACH Unaffected.

Q: Why does TLV431ACLP have a narrower operating temperature range than the substitutes?

A: TLV431ACLP operates from 0°C to 70°C, while both substitute parts operate from -40°C to 85°C. This reflects the Last Time Buy status of the original part versus the Active status of the substitutes. The extended temperature range of substitute parts provides greater design flexibility for applications requiring wider operating conditions.

Q: Can LMV431AIM5/NOPB be used in applications designed for 6V maximum output?

A: Yes. LMV431AIM5/NOPB supports output voltages up to 30V, which encompasses the 6V maximum requirement. The adjustable output range (1.24V to 30V) is a superset of the original part's range (1.24V to 6V), making it electrically compatible for applications requiring 6V or lower output.
