Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TL432CDBVRG4 must maintain electrical and mechanical compatibility based on the following critical parameters:

Electrical Compatibility Criteria:

• Reference Type: Shunt voltage reference
• Output Type: Adjustable
• Voltage Output Range: Minimum 2.495V, Maximum 36V
• Output Current: 100 mA capability
• Current - Cathode: 1 mA minimum
• Tolerance: ±2.2% or better

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package compatibility with SOT-23 family pinouts

The TL431MFDT,215 manufactured by NXP Semiconductors meets these substitution criteria. Both components share the same base product number (TL431), identical electrical output specifications, and compatible surface mount packaging within the SOT-23 family.

Parameter Comparison

Engineering Selection Recommendations

The TL431MFDT,215 is the manufacturer-recommended substitute for the obsolete TL432CDBVRG4. Selection of this substitute is justified on the following basis:

Product Status: The TL431MFDT,215 maintains active product status with NXP Semiconductors, ensuring continued availability and supply chain reliability compared to the obsolete TL432CDBVRG4.

Electrical Equivalence: Both components share identical core electrical specifications: adjustable shunt voltage reference output from 2.495V to 36V at 100 mA, with 1 mA cathode current. The TL431MFDT,215 provides superior tolerance (±2% versus ±2.2%), which represents an improvement in precision.

Compliance & Certifications: Both components maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH compliance status. The TL432CDBVRG4 is ROHS3 compliant; compliance status for the TL431MFDT,215 is not specified in available data.

Operating Temperature Range: The TL431MFDT,215 supports an extended operating temperature range (-40°C ~ 125°C) compared to the TL432CDBVRG4 (0°C ~ 70°C), providing greater flexibility for diverse application environments.

Package Compatibility: Both components use surface mount SOT-23 family packaging. Pinout verification is required prior to board-level substitution to ensure mechanical and electrical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the TL431MFDT,215 directly replace the TL432CDBVRG4 in existing designs?

A: Direct replacement requires verification of pinout compatibility. Both components use SOT-23 family surface mount packages, but specific pin assignments must be confirmed against schematic and PCB layout documentation before substitution.

Q: What are the key electrical differences between these components?

A: The primary electrical difference is tolerance specification: TL432CDBVRG4 is ±2.2%, while TL431MFDT,215 is ±2%. Both maintain identical output voltage range (2.495V to 36V) and current specifications (100 mA output, 1 mA cathode). The TL431MFDT,215 offers improved precision.

Q: Why is the TL432CDBVRG4 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The TL431MFDT,215, as an active product from NXP Semiconductors, provides a viable path for continued component sourcing and design continuity.

Q: Are there temperature range considerations for substitution?

A: The TL431MFDT,215 supports a wider operating temperature range (-40°C ~ 125°C) compared to the TL432CDBVRG4 (0°C ~ 70°C). Applications operating within the TL432CDBVRG4 temperature range will function within the TL431MFDT,215 specifications. Applications requiring extended temperature operation benefit from the substitute's broader range.

Q: What compliance certifications apply to both components?

A: Both components maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH compliance. The TL432CDBVRG4 is explicitly ROHS3 compliant. Compliance documentation for the TL431MFDT,215 should be verified with the supplier for specific regulatory requirements.

Q: How should package selection be handled during substitution?

A: The TL432CDBVRG4 is supplied in SOT-23-5 package. The TL431MFDT,215 is available in TO-236AB package. Both are SOT-23 family variants. PCB layout compatibility must be verified, including pad spacing, trace routing, and component placement constraints specific to your design.
