CPC7220W Equivalent & Substitute Parts
Part Overview
The CPC7220W is an 8-channel analog switch IC manufactured by IXYS Integrated Circuits Division, designed for ultrasound applications. This interface component features buffered switching capability with SPST (Single Pole Single Throw) configuration in a 28-PLCC package. The product is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation
Substitution eligibility for the CPC7220W is determined by the following critical parameters:
- Number of Channels: Must be 8 channels
- Switch Circuit Type: Must be SPST configuration
- Multiplexer/Demultiplexer Circuit: Must be 1:1 ratio
- On-State Resistance: Maximum 38Ω
- Voltage Supply Range: Must accommodate 4.5V ~ 6V single supply operation
- Operating Temperature Range: Must support 0°C ~ 70°C
- Mounting Type: Surface Mount required
- Features: Buffered switching capability
- Compliance: ROHS3 Compliant, MSL Level 1
Two substitute parts meet these criteria with varying package configurations and extended supply voltage ranges.

Engineering Selection Recommendations
CPC7220K is the manufacturer-recommended substitute from IXYS Integrated Circuits Division. It maintains identical electrical specifications and compliance certifications as the CPC7220W. The primary difference is the package configuration (48-LQFP versus 28-PLCC), which requires PCB layout modification. This part is currently active in production with confirmed inventory availability.
MAX4800CQI+T from Analog Devices Inc./Maxim Integrated provides an alternative substitute that maintains the original 28-PLCC package footprint, eliminating PCB redesign requirements. This part offers an extended supply voltage range (2.7V ~ 13.2V) that encompasses the CPC7220W operating range. The MAX4800CQI+T is active in production with higher inventory levels and meets all ROHS3 and MSL compliance requirements.
Selection between these substitutes depends on design constraints: CPC7220K for manufacturer continuity within the IXYS product line, or MAX4800CQI+T for package compatibility and extended voltage flexibility.
Frequently Asked Questions (FAQ)
Q: Can CPC7220K be used as a direct replacement for CPC7220W?
A: CPC7220K is electrically equivalent and meets all functional requirements. However, the package change from 28-PLCC to 48-LQFP requires PCB layout modification. Pin assignments and electrical performance are compatible.
Q: What is the primary advantage of MAX4800CQI+T over CPC7220K?
A: MAX4800CQI+T retains the original 28-PLCC package, allowing direct PCB footprint compatibility without layout redesign. It also provides extended supply voltage range (2.7V ~ 13.2V) for greater design flexibility.
Q: Are both substitute parts compliant with the same standards as CPC7220W?
A: Yes. Both CPC7220K and MAX4800CQI+T are ROHS3 compliant with MSL Level 1 rating, matching the original part's compliance profile.
Q: What is the on-state resistance specification for all three parts?
A: All three parts (CPC7220W, CPC7220K, and MAX4800CQI+T) specify a maximum on-state resistance of 38Ω, ensuring equivalent signal path performance.
Q: Are there any temperature or supply voltage limitations when substituting?
A: All three parts operate across 0°C ~ 70°C. The CPC7220W and CPC7220K require 4.5V ~ 6V supply, while MAX4800CQI+T accepts 2.7V ~ 13.2V. Verify your design supply voltage falls within the selected part's range.
Q: What inventory status should I consider for procurement?
A: CPC7220W is discontinued. CPC7220K and MAX4800CQI+T are both active with confirmed stock availability, making either suitable for new procurement.
