P82B96PWR Equivalent & Substitute Parts

Part Overview

The P82B96PWR is a 2-channel I2C buffer and redriver IC manufactured by Texas Instruments, supplied in 8-TSSOP packaging with Cut Tape (CT) & Digi-Reel® format. This interface component operates across a wide voltage range of 2V to 15V and supports I2C bus applications with a maximum data rate of 400kHz. The part is currently in active production status with 15,600 units in stock.

Substitute parts are necessary when the original P82B96PWR becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design modifications necessitate different electrical characteristics while maintaining functional compatibility within I2C bus applications.

Substitute Part Grouping Explanation

Substitution eligibility for the P82B96PWR is determined by the following critical parameters:

Primary Substitution Criteria:

Number of Channels: Must be 2 channels to maintain functional equivalence
Data Rate (Max): Must support 400kHz minimum
Voltage - Supply: Must accommodate the 2V ~ 15V operating range or a subset thereof
Operating Temperature: Must support -40°C ~ 85°C range
Applications: Must support I2C bus interface
Input/Output Configuration: Must maintain 2-Wire Bus input and output

Secondary Considerations:

Package format compatibility with manufacturing process
Current supply requirements
Input capacitance specifications
Product status and availability

Parts are grouped into two categories: direct equivalents with identical channel count and voltage range, and functional alternatives with compatible electrical characteristics but different packaging or supply current specifications.

Engineering Selection Recommendations

Direct Equivalents (2-Channel, 2V ~ 15V Supply):

The P82B96TD series (P82B96TD,112, P82B96TD,118, and P82B96TD/S900,118) from NXP USA Inc. are functionally equivalent to the P82B96PWR. All three variants maintain 2-channel configuration, 400kHz data rate, and 2V ~ 15V supply voltage range. These parts are in active production status and ROHS3 compliant. The primary difference is packaging format: 8-SOIC instead of 8-TSSOP. Current supply is reduced to 900µA compared to 4mA in the original part. These substitutes are suitable when 8-SOIC packaging is compatible with manufacturing processes.

Limited Voltage Range Alternative:

The PCA9509DP,118 from NXP USA Inc. maintains 2-channel configuration and 8-TSSOP packaging identical to the P82B96PWR. However, the supply voltage range is restricted to 3V ~ 5.5V, which does not accommodate the full 2V ~ 15V range of the original part. This substitute is applicable only in designs where the supply voltage remains within the 3V ~ 5.5V window. The part is in active production status and ROHS3 compliant.

Single-Channel Alternatives:

Parts with single-channel configuration (P82B715TD series, PCA9507 series, PCA9508 series) do not provide functional equivalence for 2-channel applications. These are listed as documented substitutes but require circuit redesign to implement dual-channel functionality through multiple devices.

Obsolete Parts:

The P82B715TD,112 and P82B715TD,118 are marked as obsolete and should not be selected for new designs despite appearing in the substitute list.

Frequently Asked Questions (FAQ)

Q: Can I substitute P82B96PWR with P82B96TD,118?

A: Yes. Both parts maintain 2-channel I2C redriver functionality, 400kHz data rate, and 2V ~ 15V supply voltage range. The primary difference is package format: P82B96TD,118 uses 8-SOIC instead of 8-TSSOP. Verify that your PCB layout and manufacturing process accommodate 8-SOIC packaging before substitution.

Q: What is the difference between P82B96TD,112 and P82B96TD,118?

A: Both parts are electrically identical 2-channel I2C redrivers with the same electrical specifications. The difference is packaging format: P82B96TD,112 is supplied in Tube packaging, while P82B96TD,118 is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on your manufacturing process requirements.

Q: Can I use PCA9509DP,118 as a direct replacement for P82B96PWR?

A: PCA9509DP,118 maintains 2-channel configuration and 8-TSSOP packaging, but the supply voltage range is limited to 3V ~ 5.5V. Use this substitute only if your design operates within this voltage window. The original P82B96PWR supports 2V ~ 15V.

Q: Why are single-channel parts listed as substitutes?

A: Single-channel parts (P82B715TD, PCA9507, PCA9508 series) are documented in the substitute field but do not provide functional equivalence for 2-channel applications. These require circuit redesign and are not recommended as direct replacements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, consistent with the original P82B96PWR.

Q: What is the impact of reduced current supply in P82B96TD variants?

A: The P82B96TD series draws 900µA compared to 4mA in the P82B96PWR. This reduction in supply current may improve power efficiency in battery-powered applications. Verify that your power supply design accommodates this lower current requirement.

Q: Can I use parts from different manufacturers interchangeably?

A: Parts from Texas Instruments (P82B96PWR) and NXP USA Inc. (P82B96TD series) maintain identical electrical specifications for 2-channel, 400kHz I2C redriver functionality. Substitution is valid based on electrical compatibility, though manufacturing and support channels may differ between suppliers.
