TL432QDBVRG4 Equivalent & Substitute Parts

Part Overview

The TL432QDBVRG4 is a shunt voltage reference IC manufactured by Texas Instruments, designed for adjustable precision voltage regulation applications. This component operates with an adjustable output range from 2.495V to 36V, delivering up to 100mA output current with ±2.2% tolerance. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. Active alternatives with equivalent electrical performance are available to maintain system functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL432QDBVRG4 is determined by equivalence in the following critical electrical parameters:

• Reference Type: Shunt voltage reference
• Output Type: Adjustable
• Voltage - Output (Min/Fixed): 2.495V
• Voltage - Output (Max): 36V
• Current - Output: 100mA
• Current - Cathode: 1mA
• Operating Temperature Range: -40°C ~ 125°C (TA)
• Mounting Type: Surface Mount

Two substitute parts meet these electrical criteria. The TL432QDBZR maintains identical electrical specifications and is manufactured by the same supplier (Texas Instruments) with active product status. The TL431MFDT,215 from NXP Semiconductors provides equivalent electrical performance with a tolerance specification of ±2%, which is tighter than the original ±2.2%, ensuring compatibility in applications requiring the original tolerance or better.

Package differences exist between the main part (SOT-23-5) and substitutes (SOT-23-3 and TO-236AB), requiring PCB layout verification for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are suitable for replacing the obsolete TL432QDBVRG4 based on electrical parameter equivalence.

The TL432QDBZR is the primary recommendation. It is manufactured by Texas Instruments (original supplier), maintains identical electrical specifications including ±2.2% tolerance, carries active product status, and holds ROHS3 compliance certification. This part provides direct functional continuity with the original design.

The TL431MFDT,215 from NXP Semiconductors is an alternative option. It meets all electrical requirements with improved tolerance performance (±2% versus ±2.2%), ensuring enhanced precision in voltage regulation. The part maintains active product status and MSL rating. Moisture Sensitivity Level compliance is confirmed at MSL 1 (Unlimited).

Package differences require PCB layout assessment. The original TL432QDBVRG4 uses SOT-23-5 packaging, while both substitutes employ SOT-23-3 or TO-236AB packaging. Pin configuration and footprint compatibility must be verified before implementation.

Frequently Asked Questions (FAQ)

Q: Can the TL432QDBZR directly replace the TL432QDBVRG4 without PCB modifications?

A: Electrical substitution is valid. However, package differences (SOT-23-5 versus SOT-23-3) require PCB footprint verification. Pin-to-pin compatibility must be confirmed before soldering.

Q: What is the difference between the TL432QDBZR and TL431MFDT,215?

A: Both parts meet the electrical requirements of the original component. The TL432QDBZR is manufactured by Texas Instruments with ±2.2% tolerance. The TL431MFDT,215 is manufactured by NXP Semiconductors with ±2% tolerance, offering tighter precision. Both operate within the same voltage and current ranges and temperature specifications.

Q: Is the improved tolerance of the TL431MFDT,215 (±2% versus ±2.2%) compatible with designs specified for ±2.2%?

A: Yes. Tighter tolerance specifications are compatible with applications designed for the original tolerance. The ±2% specification of the TL431MFDT,215 falls within the acceptable range for circuits designed around ±2.2% tolerance.

Q: Are both substitute parts RoHS compliant?

A: The TL432QDBZR carries ROHS3 compliance certification. The TL431MFDT,215 RoHS status is not specified in the provided data. Compliance verification with the component supplier is recommended for the NXP part if RoHS certification is a design requirement.

Q: What is the MSL rating for these parts, and does it affect storage or handling?

A: Both substitute parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements. Standard surface mount handling procedures apply.

Q: Can I use either substitute part interchangeably in my design?

A: Electrical interchangeability is confirmed for both parts. Package footprint compatibility must be verified for your specific PCB layout. Once footprint compatibility is established, either part can be selected based on availability, supplier preference, or tolerance requirements.
