TL432BIDBVR Equivalent & Substitute Parts

Part Overview

The TL432BIDBVR is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision voltage regulation and reference 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 operates across the industrial temperature range of -40°C to 85°C and is packaged in SOT-23-5 (SC-74A) surface mount configuration.

The TL432BIDBVR is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL432BIDBVR is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Reference type must be shunt
• Output type must be adjustable
• Minimum output voltage: 2.495V
• Maximum output voltage: 36V or greater
• Output current capability: 100mA or greater
• Tolerance: ±0.5% or better
• Cathode current: must not exceed application requirements

Mechanical & Environmental Requirements:

• Surface mount packaging only
• Operating temperature range must cover or exceed -40°C to 85°C
• RoHS3 compliance required
• REACH compliance status must be unaffected

The AS431HANTR-G1 manufactured by Diodes Incorporated meets all substitution criteria. While it uses a different package variant (SOT-23-3 versus SOT-23-5), both are surface mount configurations with compatible pinout arrangements for shunt reference applications. The AS431HANTR-G1 maintains identical electrical specifications for voltage output, tolerance, and current capability while offering active product status and extended temperature range support.

Parameter Comparison

Engineering Selection Recommendations

The AS431HANTR-G1 is a direct functional equivalent for the TL432BIDBVR based on electrical and compliance specifications. Both devices are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

The AS431HANTR-G1 offers the advantage of active product status, ensuring continued availability and manufacturing support. The extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) provides additional thermal margin for applications operating at elevated ambient temperatures.

Package differences exist between the two devices (SOT-23-5 versus SOT-23-3). PCB layout modifications may be required to accommodate the different pin configurations. Both packages are industry-standard surface mount formats with established manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the AS431HANTR-G1 directly replace the TL432BIDBVR without circuit modifications?

A: The AS431HANTR-G1 is electrically equivalent and maintains identical voltage reference specifications, output current capability, and tolerance. However, the package change from SOT-23-5 to SOT-23-3 requires PCB footprint modification. Pin assignments differ between the two packages, necessitating layout redesign.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by reference type (shunt), output type (adjustable), output voltage range (2.495V to 36V), output current (100mA), and tolerance (±0.5%). The AS431HANTR-G1 matches all these specifications.

Q: Does the AS431HANTR-G1 support the same operating temperature range?

A: The AS431HANTR-G1 supports -40°C to 125°C, which exceeds the TL432BIDBVR range of -40°C to 85°C. This provides additional thermal headroom for applications requiring extended temperature operation.

Q: Are both devices RoHS and REACH compliant?

A: Yes. Both the TL432BIDBVR and AS431HANTR-G1 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial applications.

Q: What is the significance of the product status difference?

A: The TL432BIDBVR is obsolete, indicating end-of-life status and potential supply constraints. The AS431HANTR-G1 is active, ensuring continued manufacturing availability and long-term supply chain reliability.
