P82B96PW Equivalent & Substitute Parts

Part Overview

The P82B96PW is a Buffer/ReDriver interface IC designed for I2C applications, featuring 2-channel 400kHz operation in an 8-TSSOP package. Manufactured by Texas Instruments, this component operates across a 2V to 15V supply range with 4mA current consumption and supports -40°C to 85°C operating temperatures. The part is currently in Last Time Buy status, indicating production discontinuation. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs or long-term support.

Substitute Part Grouping Explanation

Substitution for the P82B96PW is determined by the following critical parameters: I2C application compatibility, 2-channel configuration, 400kHz maximum data rate, 2V to 15V supply voltage range, and surface mount packaging. Parts are grouped into three categories based on substitution viability:

Category 1: Direct Functional Equivalents (Same Base Product, Different Packaging) Parts sharing the P82B96 base product number with identical electrical specifications but alternative packaging formats. These maintain full functional compatibility while offering different supply chain options.

Category 2: Parametric Equivalents (Obsolete Variants) Parts with matching electrical parameters but obsolete product status. These provide functional substitution but may have limited availability.

Category 3: Partial Equivalents (Different Channel Count or Package) Parts with compatible I2C operation and 400kHz data rate but differing in channel count or package type. These require design verification for specific applications.

Engineering Selection Recommendations

Primary Recommendation: P82B96PWR The P82B96PWR is the direct functional equivalent with identical electrical specifications and 8-TSSOP packaging. It maintains Active product status with significantly higher inventory availability (15600 Pcs), ensuring long-term supply chain stability. This part is the preferred replacement for P82B96PW applications.

Secondary Recommendation: P82B96TD Series (NXP) The P82B96TD,118 and P82B96TD/S900,118 variants provide 2-channel, 400kHz I2C operation with identical supply voltage range. These parts feature reduced current consumption (900µA vs 4mA) and are available in 8-SOIC packaging. Both maintain Active product status with substantial inventory. Design layout modification is required due to package change from 8-TSSOP to 8-SOIC.

Conditional Recommendation: P82B715TD Series The P82B715TD variants are single-channel alternatives with 400kHz I2C capability. These parts are suitable only for applications requiring single-channel operation. Both variants are Obsolete with restricted supply availability. The narrower supply voltage range (4.5V ~ 12V) and higher current consumption (22mA) limit applicability.

Limited Recommendation: PCA9507 Series The PCA9507DP,118 and PCA9507D,118 are single-channel Buffer/Accelerator devices supporting both HDMI and I2C applications at 400kHz. These parts are suitable only for single-channel I2C designs. The restricted supply voltage range (2.7V ~ 5.5V) requires verification against system requirements.

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 rating, and -40°C to 85°C operating temperature range consistent with the original P82B96PW specification.

Frequently Asked Questions (FAQ)

Q: Can P82B96PWR directly replace P82B96PW without PCB modification? A: Yes. P82B96PWR is functionally identical with matching 8-TSSOP packaging, pinout, and electrical specifications. No PCB layout changes are required.

Q: What is the difference between P82B96PWR and P82B96TD,118? A: Both provide 2-channel 400kHz I2C operation with 2V to 15V supply compatibility. The primary differences are packaging (8-TSSOP vs 8-SOIC) and current consumption (4mA vs 900µA). P82B96TD,118 requires PCB redesign due to package change but offers lower power consumption.

Q: Are P82B715TD variants suitable replacements for 2-channel applications? A: No. P82B715TD parts provide only single-channel operation, making them unsuitable for applications requiring 2-channel I2C buffering. These parts are recommended only for single-channel designs.

Q: What supply voltage range must be verified when considering PCA9507 substitutes? A: PCA9507 variants operate within 2.7V to 5.5V, which is narrower than the P82B96PW range of 2V to 15V. Applications requiring operation below 2.7V or above 5.5V cannot use PCA9507 parts.

Q: Why is P82B96PWG4 listed as Obsolete despite matching specifications? A: P82B96PWG4 is an obsolete variant of the P82B96 base product. While electrically equivalent, its Obsolete status indicates discontinued manufacturing. P82B96PWR is the Active equivalent with superior availability.

Q: Does packaging change from 8-TSSOP to 8-SOIC affect electrical performance? A: No. Both 8-TSSOP and 8-SOIC packages maintain identical electrical specifications and pinout compatibility for the P82B96 base product. PCB layout and footprint design must be updated to accommodate the different physical dimensions.

Q: What is the significance of the ",118" suffix in NXP part numbers? A: The ",118" suffix indicates Cut Tape (CT) and Digi-Reel packaging format. This is a supply chain designation and does not affect electrical specifications or functionality compared to Tube packaging variants.

Q: Can multiple PCA9507 single-channel parts replace one P82B96PW dual-channel part? A: Functionally yes, but this requires significant circuit redesign. Two PCA9507 devices would be needed to achieve dual-channel operation, increasing component count, PCB area, and power consumption. This approach is not recommended for space-constrained or power-sensitive applications.
