Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSH222S-CEC are identified based on the following criteria:

Functional Compatibility:

• Both parts operate as full-duplex retimers
• Both comply with IEEE 802.3 interface standards
• Both are manufactured by MoSys, Inc.

Physical Compatibility:

• Both utilize Surface Mount mounting technology
• Both employ FCBGA ball grid array packaging
• Both maintain identical Moisture Sensitivity Level (MSL 4, 72 Hours)

Substitution Basis: The MSH225S-CDC serves as a substitute for the MSH222S-CEC. While the MSH225S-CDC features a larger 256-FCBGA (17x17) package and supports 10-lane full-duplex retiming compared to the quad configuration of the original part, both components share the same interface standard, mounting methodology, and environmental specifications. The substitute part is currently in Active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MSH222S-CEC is classified as Obsolete, which restricts long-term availability and manufacturer support. The MSH225S-CDC is classified as Active, ensuring continued supply chain access and technical support from MoSys, Inc.

Compliance and Certification: Both parts maintain identical Moisture Sensitivity Level specifications (MSL 4, 72 Hours), ensuring equivalent handling and storage requirements. The MSH225S-CDC carries EAR99 export classification, providing regulatory clarity for international applications.

Interface Compatibility: Both components comply with IEEE 802.3 standards, maintaining functional compatibility within retimer interface applications. Surface Mount mounting technology is consistent across both parts, allowing for compatible PCB assembly processes.

Package Consideration: The MSH225S-CDC utilizes a larger 256-FCBGA (17x17) package compared to the 144-FCBGA (13x13) of the MSH222S-CEC. This difference requires PCB layout modification and increased board real estate. The substitute part supports 10-lane full-duplex retiming, providing enhanced lane capacity relative to the quad configuration of the original part.

Frequently Asked Questions (FAQ)

Q: Can the MSH225S-CDC directly replace the MSH222S-CEC without PCB modifications?

A: No. The MSH225S-CDC uses a 256-FCBGA (17x17) package, while the MSH222S-CEC uses a 144-FCBGA (13x13) package. PCB layout redesign is required to accommodate the larger ball grid array footprint and increased pin count.

Q: Are the moisture sensitivity requirements identical between these parts?

A: Yes. Both the MSH222S-CEC and MSH225S-CDC maintain MSL 4 (72 Hours) specifications, requiring identical handling, storage, and reflow procedures.

Q: What is the primary functional difference between these retimer interfaces?

A: The MSH222S-CEC provides quad full-duplex retiming capability, while the MSH225S-CDC provides 10-lane full-duplex retiming. The substitute part offers increased lane capacity for higher-bandwidth applications.

Q: Why is the MSH222S-CEC classified as Obsolete?

A: Obsolete classification indicates that the manufacturer has discontinued production and support for this component. The MSH225S-CDC, classified as Active, represents the current-generation alternative from MoSys, Inc.

Q: Do both parts comply with the same interface standard?

A: Yes. Both the MSH222S-CEC and MSH225S-CDC comply with IEEE 802.3 interface standards, ensuring functional compatibility within retimer applications.

Q: What packaging format is available for the MSH225S-CDC?

A: The MSH225S-CDC is supplied in Tray packaging, suitable for automated assembly processes and high-volume production environments.

Q: Are there any export restrictions associated with the MSH225S-CDC?

A: The MSH225S-CDC carries EAR99 export classification, which provides standard export control treatment and does not impose additional restrictions beyond standard regulatory compliance.
