PI5C3384QEX Equivalent & Substitute Parts
Part Overview
The PI5C3384QEX is a bus switch logic IC manufactured by Diodes Incorporated, configured as a 5 x 1:1 multiplexer in a 24-QSOP package. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. Bus switches of this type are essential for signal routing and multiplexing applications in digital systems where multiple input sources must be selectively connected to a single output path. Equivalent and substitute parts are necessary to ensure design continuity and long-term component availability for production and maintenance applications.

Substitute Part Grouping Explanation
Substitution of the PI5C3384QEX is determined by strict equivalence across the following critical parameters:
- Circuit Configuration: All substitutes must maintain 5 x 1:1 multiplexer topology with 2 independent circuits
- Voltage Supply Range: Operating voltage must be compatible; the PI5C3384QEX operates at 4.75V ~ 5.25V
- Operating Temperature Range: Must support -40°C ~ 85°C minimum
- Package Compatibility: Physical package dimensions and pin count must match or be mechanically compatible
- RoHS and Compliance Status: All substitutes must maintain ROHS3 compliance and REACH unaffected status
Substitute parts are grouped into two categories based on package type: 24-SSOP (0.154" width) and 24-TSSOP (0.173" width). While both package types share identical pin counts and electrical specifications, mechanical compatibility must be verified for PCB layout and assembly processes.

Engineering Selection Recommendations
Direct Electrical Equivalents (24-SSOP Package)
The QS3384QG and QS3384QG8 from Renesas Electronics are direct electrical equivalents to the PI5C3384QEX. Both maintain identical voltage supply specifications (4.75V ~ 5.25V), operating temperature range (-40°C ~ 85°C), and package dimensions (24-SSOP, 0.154" width). Both parts carry Active product status, ensuring long-term availability. These parts are recommended as primary substitutes for applications requiring the 24-SSOP package form factor.
Voltage-Compatible Alternatives (24-SSOP Package)
The SN74CBT3384CDBQR from Texas Instruments operates within a broader voltage supply range (4.5V ~ 5.5V), which encompasses the PI5C3384QEX specification. This part maintains the 24-SSOP package and carries Active product status. The SN74CBT3384ADBQR is also electrically compatible but carries Last Time Buy status, limiting its suitability for new designs.
Package-Alternative Substitutes (24-TSSOP Package)
For applications where package footprint flexibility exists, the SN74CBT3384CPWR and SN74CBT3384CPW from Texas Instruments provide Active product status with identical electrical specifications. These parts use the 24-TSSOP package (0.173" width) and require PCB layout modification. The CBT3384PW,118 from NXP Semiconductors is also available in 24-TSSOP format with Active status.
Product Status Considerations
Parts with Active product status (QS3384QG, QS3384QG8, SN74CBT3384CDBQR, SN74CBT3384CPW, SN74CBT3384CPWR, CBT3384PW,118) are recommended for new designs and long-term production. Parts with Last Time Buy status should be reserved for legacy system maintenance only.
Frequently Asked Questions (FAQ)
Q: Can I substitute the PI5C3384QEX with any of the listed alternatives without PCB modification?
A: Direct substitution without PCB modification is limited to parts with identical package types. The QS3384QG and QS3384QG8 (24-SSOP, 0.154" width) are pin-compatible and footprint-compatible. Texas Instruments parts in 24-TSSOP format (0.173" width) require PCB layout changes due to different package dimensions.
Q: What is the difference between the voltage supply ranges 4.75V ~ 5.25V and 4.5V ~ 5.5V?
A: The PI5C3384QEX operates within a narrower voltage window (4.75V ~ 5.25V), while Texas Instruments CBT3384 variants accept a broader range (4.5V ~ 5.5V). Both ranges are compatible with standard 5V supply systems. The broader range of Texas Instruments parts provides additional design margin in applications with variable supply voltages.
Q: Are all listed substitutes RoHS3 compliant?
A: All substitutes except CBT3384PW,118 explicitly state ROHS3 compliance. The CBT3384PW,118 does not specify RoHS status in the provided data. Compliance verification with the supplier is recommended before selection.
Q: What does MSL (Moisture Sensitivity Level) mean for component selection?
A: MSL indicates moisture sensitivity during storage and handling. MSL 1 (Unlimited) parts have no moisture-related storage restrictions. MSL 2 (1 Year) parts require controlled storage conditions and have a one-year shelf life limit. For applications with extended storage or high-humidity environments, MSL 1 parts are preferred.
Q: Can I use Last Time Buy parts in new product designs?
A: Last Time Buy parts should not be used in new designs due to limited inventory and discontinued production. These parts are suitable only for maintenance and repair of existing systems. For new designs, select parts with Active product status.
Q: What is the difference between tube and tape & reel packaging?
A: Tube packaging is suitable for manual assembly and small-volume production. Tape & reel packaging is designed for automated pick-and-place assembly equipment and high-volume manufacturing. Selection depends on production volume and assembly process capabilities.
