TL432BQDBVR Equivalent & Substitute Parts

Part Overview

The TL432BQDBVR is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision voltage regulation applications. This adjustable reference provides a fixed output of 2.495V with a maximum output capability of 36V and supports up to 100mA output current. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL432BQDBVR is determined by strict equivalence across the following critical parameters:

Reference Type and Output Type must remain constant (Shunt, Adjustable). Voltage specifications including minimum fixed output (2.495V) and maximum output (36V) must be identical. Current output capability (100mA) and tolerance (±0.5%) establish the performance baseline. Package and case designation (SC-74A, SOT-753) ensure mechanical and electrical compatibility with existing PCB layouts. RoHS3 compliance and REACH unaffected status maintain regulatory alignment.

The TL432BCDBVR qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the allowed specification range.

Parameter Comparison

Engineering Selection Recommendations

The TL432BCDBVR is the designated substitute for the obsolete TL432BQDBVR. Both devices maintain identical electrical specifications for voltage reference output, current capacity, and tolerance performance. The substitute part is currently in active production status with 2300 units available in inventory, ensuring supply chain continuity.

The TL432BCDBVR operates within a narrower temperature range (0°C ~ 70°C versus -40°C ~ 125°C) and exhibits slightly lower cathode current (600µA versus 700µA). These differences are non-critical for standard industrial applications operating within commercial temperature ranges. Applications requiring extended temperature operation below 0°C or above 70°C must evaluate thermal performance independently.

Both parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can TL432BCDBVR directly replace TL432BQDBVR in existing designs?

A: Yes. Both parts share identical voltage reference specifications (2.495V adjustable output, 36V maximum), current output (100mA), tolerance (±0.5%), and package designation (SOT-23-5). PCB layout and schematic compatibility is maintained.

Q: What are the differences between these parts?

A: The primary differences are product status (substitute is active versus obsolete), operating temperature range (0°C ~ 70°C versus -40°C ~ 125°C), and cathode current (600µA versus 700µA). The substitute part is suitable for commercial temperature applications.

Q: Does the lower cathode current of TL432BCDBVR affect circuit performance?

A: The 100µA reduction in cathode current (700µA to 600µA) does not impact output voltage regulation or current delivery specifications. Circuit designs based on the main part specifications remain valid with the substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both TL432BQDBVR and TL432BCDBVR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging is used for the TL432BCDBVR?

A: The substitute is supplied in Tape & Reel (TR) packaging in the SC-74A, SOT-753 surface mount package, identical to the main part case designation.
