Substitute Part Grouping Explanation
Substitution for the PCA9513DP,118 is determined by the following critical parameters: I2C hotswap application compatibility, 400kHz data rate capability, single-channel configuration, 2.7V to 5.5V supply voltage range, -40°C to 85°C operating temperature range, and surface mount packaging in 8-pin configurations (8-TSSOP or 8-MSOP). Parts are grouped into two categories:
Direct Functional Equivalents: Parts maintaining identical electrical specifications and package compatibility, including the active-status PCA9513ADP,118 and PCA9512ADP,118 from NXP, as well as LTC4313 series variants from Analog Devices and TCA4311ADGKR from Texas Instruments.
Parametric Alternatives: The LTC1694-1CS5#TRMPBF operates at reduced data rates (100kHz) and different package format (TSOT-23-5), suitable only for applications not requiring 400kHz performance.

Engineering Selection Recommendations
Primary Substitutes (Active Status, Full Compatibility):
PCA9513ADP,118 and PCA9512ADP,118 are direct NXP replacements with active product status and identical electrical specifications. Both maintain the 8-TSSOP package format and support 400kHz I2C hotswap applications across the full -40°C to 85°C temperature range. PCA9512ADP,118 offers reduced supply current (1.8mA) compared to the original specification (2.8mA).
LTC4313 series parts (Analog Devices Inc.) provide active-status alternatives with 400kHz capability and -40°C to 85°C operation. These components use 8-MSOP packaging instead of 8-TSSOP, requiring PCB layout adjustment. Supply current is higher at 8.1mA. Multiple packaging options exist: tube packaging (#PBF) and tape & reel (#TRPBF) formats. Inventory availability is substantial across variants.
TCA4311ADGKR (Texas Instruments) operates at 400kHz with active product status and -40°C to 85°C temperature range. This part uses 8-VSSOP packaging and draws 5.1mA supply current. Highest inventory availability (20202 Pcs) among all substitutes.
Secondary Alternative (Reduced Performance):
LTC1694-1CS5#TRMPBF operates at 100kHz maximum data rate and uses TSOT-23-5 packaging. This part is suitable only for I2C applications not requiring 400kHz performance. Operating temperature range is limited to 0°C to 70°C. Supply current is significantly reduced at 60µA.
All substitute parts carry ROHS3 compliance and EAR99 ECCN classification matching the original part.
Frequently Asked Questions (FAQ)
Q: Can I use PCA9513ADP,118 as a direct replacement for PCA9513DP,118?
A: Yes. Both parts are manufactured by NXP, operate at 400kHz, support I2C hotswap applications, use identical 8-TSSOP packaging, and maintain the same supply voltage range (2.7V to 5.5V) and operating temperature range (-40°C to 85°C). The primary difference is product status: PCA9513ADP,118 is active while PCA9513DP,118 is obsolete.
Q: What is the difference between PCA9512ADP,118 and PCA9513ADP,118?
A: Both parts operate at 400kHz with identical package and temperature specifications. PCA9512ADP,118 draws 1.8mA supply current compared to 3.5mA for PCA9513ADP,118, making it suitable for power-constrained applications. Both are active-status NXP products.
Q: Can I substitute LTC4313 series parts for the PCA9513DP,118?
A: LTC4313 variants maintain 400kHz data rate and -40°C to 85°C operation, but use 8-MSOP packaging instead of 8-TSSOP. PCB layout modifications are required. Supply current is higher at 8.1mA. Multiple packaging options exist (tube and tape & reel formats). These are active-status Analog Devices products.
Q: Is TCA4311ADGKR compatible with PCA9513DP,118 applications?
A: TCA4311ADGKR supports 400kHz I2C hotswap operation and -40°C to 85°C temperature range with active product status. It uses 8-VSSOP packaging requiring PCB layout adjustment. Supply current is 5.1mA. This Texas Instruments part is functionally compatible but requires package-level design changes.
Q: When should I use LTC1694-1CS5#TRMPBF instead of other substitutes?
A: LTC1694-1CS5#TRMPBF is suitable only for I2C applications operating at 100kHz or lower. It is not compatible with 400kHz systems. Operating temperature range is limited to 0°C to 70°C. This part offers significantly reduced supply current (60µA) and uses TSOT-23-5 packaging.
Q: What packaging formats are available for LTC4313 substitutes?
A: LTC4313 parts are available in tube packaging (#PBF designation) and tape & reel packaging (#TRPBF designation). Both formats use 8-MSOP package geometry. Selection depends on assembly process requirements and volume needs.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance matching the original PCA9513DP,118 specification.
