REF3425IDBVR Equivalent & Substitute Parts

Part Overview

The REF3425IDBVR is a series voltage reference IC manufactured by Texas Instruments, designed for precision analog applications requiring stable fixed voltage outputs. This device generates a fixed 2.5V reference with ±0.05% tolerance and operates across a wide input voltage range of 3V to 12V. The part is classified as active product status and is widely used in power management and precision measurement circuits. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across the same product family and packaging standard.

Substitute Part Grouping Explanation

Substitute parts for the REF3425IDBVR are identified based on strict parametric equivalence within the REF34xx series family. The substitution criteria are limited to the following electrical and mechanical parameters:

• Fixed output voltage of 2.5V
• Output current rating of 10 mA
• Tolerance specification of ±0.05%
• Temperature coefficient of 6 ppm/°C
• Noise characteristics (0.1Hz to 10Hz: 5 µVp-p; 10Hz to 10kHz: 24 µVrms)
• Input voltage range of 3V ~ 12V
• Supply current of 95 µA
• Operating temperature range of -40°C ~ 125°C
• SOT-23-6 package configuration
• Surface mount mounting type
• Active product status
• ROHS3 compliance

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in qualification level or grade do not affect electrical substitutability when all core parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The REF3425IDBVR and REF3425QDBVRQ1 are parametric equivalents with identical electrical and mechanical specifications. Both devices are active products with ROHS3 compliance and MSL 2 rating.

The REF3425QDBVRQ1 carries automotive-grade qualification (AEC-Q100), making it suitable for applications requiring automotive reliability standards. The REF3425IDBVR is specified for industrial-grade applications. Selection between these parts depends on the application environment and compliance requirements rather than electrical performance, as all core parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can REF3425QDBVRQ1 be used as a direct replacement for REF3425IDBVR?

A: Yes. Both parts share identical electrical specifications including output voltage, tolerance, temperature coefficient, noise characteristics, and operating ranges. The SOT-23-6 package and surface mount configuration are identical. The primary difference is the automotive-grade qualification of the REF3425QDBVRQ1, which does not affect electrical substitutability.

Q: What is the significance of the AEC-Q100 qualification on the REF3425QDBVRQ1?

A: AEC-Q100 is an automotive industry qualification standard. This certification indicates the part has been tested and validated for automotive applications. If your application requires automotive-grade components, the REF3425QDBVRQ1 is the appropriate selection.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the SOT-23-6 package configuration with identical mechanical specifications, pin assignments, and surface mount footprints.

Q: What parameters determine substitutability for the REF3425IDBVR?

A: Substitutability is determined by matching the following parameters: fixed 2.5V output voltage, 10 mA output current, ±0.05% tolerance, 6 ppm/°C temperature coefficient, specified noise characteristics, 3V to 12V input range, 95 µA supply current, -40°C to 125°C operating temperature, SOT-23-6 package, and active product status.

Q: Can parts from other manufacturers substitute for the REF3425IDBVR?

A: Substitution is limited to parts within the REF34xx series from Texas Instruments that meet all specified electrical and mechanical parameters. Cross-manufacturer substitution requires verification of identical parametric specifications and package compatibility.
