PCA9510DP,118 Equivalent & Substitute Parts

Part Overview

The PCA9510DP,118 is a Buffer/ReDriver interface IC designed for I2C hotswap applications. Manufactured by NXP USA Inc., this single-channel 400kHz device operates in the 2.7V to 5.5V supply range and is packaged in an 8-TSSOP surface-mount configuration. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring similar functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PCA9510DP,118 is determined by the following critical parameters:

• Data Rate Compatibility: 400kHz operation for I2C hotswap applications
• Channel Configuration: Single-channel or multi-channel designs with compatible I2C bus interface
• Supply Voltage Range: Minimum 2.7V support for low-power applications
• Package Compatibility: Surface-mount packages (8-TSSOP, 8-SOIC, 8-XFQFN) or through-hole alternatives (8-DIP)
• Functional Classification: Buffer/ReDriver type with 2-Wire bus input/output
• Compliance: ROHS3 compliance and operating temperature range -40°C to 85°C

Substitutes are grouped into three categories based on these parameters: direct NXP equivalents with active product status, Texas Instruments alternatives with comparable electrical characteristics, and package variants supporting different mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PCA9510ADP,118

The PCA9510ADP,118 is the direct active equivalent from NXP USA Inc. It maintains identical electrical specifications to the obsolete PCA9510DP,118, including 400kHz data rate, 2.7V to 5.5V supply range, single-channel configuration, and 8-TSSOP package. Product status is Active with ROHS3 compliance. Current supply increases marginally from 2.8mA to 4.6mA. This part is available in Cut Tape and Digi-Reel packaging with 9,687 units in stock.

Secondary Recommendation: P82B96PWR (Texas Instruments)

The P82B96PWR provides 400kHz I2C hotswap capability in an 8-TSSOP package with Active product status. It features dual-channel architecture, extended supply voltage range (2V to 15V), and lower current consumption (4mA). This part is suitable for applications requiring higher supply voltage tolerance. Available in Cut Tape and Digi-Reel packaging with 15,600 units in stock.

Alternative for Through-Hole Applications: P82B96P

For designs requiring through-hole mounting, the P82B96P offers 400kHz operation in an 8-DIP package with Active product status. It maintains the same electrical performance as P82B96PWR with 186,300 units in stock.

Compact Package Alternative: TCA9509RVHR

The TCA9509RVHR provides single-channel 400kHz operation in a compact 8-XFQFN package (1.6x1.6mm) with Active product status. Supply voltage range matches the original part (2.7V to 5.5V) with slightly lower current consumption (3mA). This option is suitable for space-constrained applications.

Not Recommended: P82B715 Series

The P82B715 series (P82B715DR, P82B715D, P82B715P) operates at higher supply voltages (4.5V to 12V minimum) and exhibits significantly higher current consumption (22mA). These parts are suitable only for applications with higher supply voltage requirements and are not direct substitutes for the PCA9510DP,118.

Frequently Asked Questions (FAQ)

Q: Can I use PCA9510ADP,118 as a direct replacement for PCA9510DP,118?

A: Yes. The PCA9510ADP,118 is the active equivalent with identical electrical specifications, package type, and functional characteristics. The only difference is product status (Active vs. Obsolete) and a minor increase in supply current from 2.8mA to 4.6mA.

Q: What is the key difference between single-channel and dual-channel I2C redrivers?

A: Single-channel devices (PCA9510ADP,118, TCA9509RVHR) condition one I2C bus. Dual-channel devices (P82B96 series) condition two independent I2C buses simultaneously. Selection depends on system architecture requirements.

Q: Can P82B96PWR replace PCA9510DP,118 in a 2.7V supply application?

A: Yes. The P82B96PWR operates from 2V to 15V, covering the 2.7V to 5.5V range of the original part. However, it provides dual-channel functionality and higher current consumption (4mA vs. 2.8mA).

Q: What are the package differences among substitute options?

A: Surface-mount options include 8-TSSOP (0.118" width), 8-SOIC (0.154" width), and 8-XFQFN (1.6x1.6mm). Through-hole option is 8-DIP (0.300" width). Package selection depends on PCB layout and assembly capabilities.

Q: Why is the P82B715 series not recommended as a substitute?

A: The P82B715 series requires minimum 4.5V supply voltage, exceeding the original part's 2.7V minimum. Current consumption is 22mA compared to 2.8mA for the original, making it unsuitable for low-power applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and operate across the -40°C to 85°C temperature range, matching the original part's environmental specifications.

Q: Which substitute offers the smallest footprint?

A: The TCA9509RVHR in 8-XFQFN package (1.6x1.6mm) provides the smallest footprint while maintaining single-channel 400kHz I2C hotswap functionality and 2.7V to 5.5V supply compatibility.
