TL432QDBVR Equivalent & Substitute Parts

Part Overview

The TL432QDBVR 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 100 mA output current with ±2.2% tolerance. The device is packaged in SOT-23-5 (SC-74A) surface mount configuration and operates across the industrial temperature range of -40°C to 125°C.

The TL432QDBVR is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. Suitable alternatives maintain the core electrical specifications while offering improved availability and active product status.

Substitute Part Grouping Explanation

Substitution for the TL432QDBVR is determined by equivalence in the following critical parameters:

• Reference Type: Shunt voltage reference architecture
• Output Type: Adjustable output voltage capability
• Voltage Range: 2.495V minimum to 36V maximum output
• Current Rating: 100 mA output current capacity
• Tolerance: ±2.2% or better voltage accuracy
• Cathode Current: 1 mA minimum operating current
• Temperature Range: -40°C to 125°C operating specification
• Mounting: Surface mount technology
• Compliance: ROHS3 and REACH requirements

The identified substitutes maintain these electrical and mechanical specifications while offering active product status and improved market availability.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain electrical equivalence with the TL432QDBVR across all critical performance parameters. Selection between substitutes is based on product status and compliance certifications:

TL432QDBZR (Texas Instruments) represents the direct manufacturer continuation with identical electrical specifications and ROHS3 compliance. This part is the primary recommendation for designs requiring Texas Instruments sourcing or existing supply chain continuity.

TL431MFDT,215 (NXP Semiconductors) provides an alternative from a qualified semiconductor manufacturer with improved tolerance specification (±2%) and active product status. This part is suitable for applications where multi-source qualification is required or NXP supply chain integration is preferred.

Both substitutes are actively manufactured and available in production quantities, addressing the obsolescence status of the original TL432QDBVR.

Frequently Asked Questions (FAQ)

Q: Can TL432QDBZR directly replace TL432QDBVR in existing designs?

A: Electrical substitution is valid. Both parts share identical voltage range (2.495V to 36V), current rating (100 mA), tolerance (±2.2%), and operating temperature specifications. Package differences exist: TL432QDBVR uses SOT-23-5 (5-pin), while TL432QDBZR uses SOT-23-3 (3-pin). PCB layout modification is required to accommodate the different pin configuration.

Q: What are the package differences between the substitutes?

A: TL432QDBVR is packaged in SOT-23-5 (SC-74A, SOT-753) with 5 pins. Both substitutes use SOT-23-3 (TO-236-3, SC-59) with 3 pins. The reduced pin count reflects functional consolidation in the substitute designs. Schematic and PCB redesign is necessary for implementation.

Q: Is TL431MFDT,215 electrically equivalent to TL432QDBVR?

A: Electrical equivalence is confirmed across all specified parameters. The TL431MFDT,215 delivers improved voltage tolerance (±2%) compared to the TL432QDBVR (±2.2%), maintaining all other specifications including voltage range, current capacity, and operating temperature. This part is manufactured by NXP Semiconductors.

Q: Which substitute offers better availability?

A: Both substitutes are active products with production inventory. TL432QDBZR shows 23,100 units in stock (Texas Instruments), while TL431MFDT,215 shows 9,221 units in stock (NXP Semiconductors). Availability should be verified with current suppliers for specific procurement timelines.

Q: Are both substitutes ROHS3 compliant?

A: TL432QDBZR is confirmed ROHS3 compliant. RoHS status for TL431MFDT,215 is not specified in the provided data. Compliance verification with the NXP supplier is recommended for applications requiring explicit ROHS3 certification.
