MSH222SF-CEC Equivalent & Substitute Parts
Part Overview
The MSH222SF-CEC is a Quad Full-Duplex Retimer with RS interface manufactured by MoSys, Inc. This component operates as a retimer interface device in a 144-FCBGA (13x13) package and supports IEEE 802.3 standards for high-speed data transmission applications. The MSH222SF-CEC is classified as obsolete, necessitating identification of active substitute components for ongoing system designs and legacy product support.

Substitute Part Grouping Explanation
Substitute components for the MSH222SF-CEC are identified based on the following criteria:
Manufacturer Continuity: Substitute parts must originate from MoSys, Inc. to ensure design consistency and technical support alignment.
Functional Category: All substitutes operate within the Interface category as Retimer devices, maintaining functional equivalence in system architecture.
Interface Standard Compliance: Substitute parts must support IEEE 802.3 standards to ensure protocol compatibility with existing network infrastructure.
Mounting Technology: All substitutes utilize Surface Mount technology with BGA packaging, ensuring compatibility with standard PCB assembly processes.
Moisture Sensitivity: Substitute parts maintain MSL 4 (72 Hours) classification, preserving handling and storage requirements.
Product Status: Active product status ensures availability, technical support, and continued manufacturing for substitute components.
The MSH225SF-CDC qualifies as a substitute based on these parameters, with the primary distinction being an increased pin count (256-FCBGA versus 144-FCBGA) to support enhanced lane capacity.

Engineering Selection Recommendations
The MSH225SF-CDC serves as an active substitute for the obsolete MSH222SF-CEC. Both components share identical manufacturer origin, functional classification, interface standards compliance, and moisture sensitivity specifications. The transition from 144-FCBGA to 256-FCBGA packaging reflects enhanced lane capacity (10-lane full-duplex configuration in the MSH225SF-CDC versus quad full-duplex in the MSH222SF-CEC).
Selection of the MSH225SF-CDC is appropriate for new designs requiring retimer functionality with IEEE 802.3 compliance. For legacy systems currently utilizing the MSH222SF-CEC, substitution requires PCB redesign to accommodate the larger 256-FCBGA (17x17) footprint and increased pin count. The active product status of the MSH225SF-CDC ensures manufacturing availability and technical support continuity.
Frequently Asked Questions (FAQ)
Q: Can the MSH225SF-CDC directly replace the MSH222SF-CEC on existing PCBs?
A: Direct PCB replacement is not possible. The MSH225SF-CDC uses a 256-FCBGA (17x17) package compared to the 144-FCBGA (13x13) package of the MSH222SF-CEC. PCB redesign is required to accommodate the larger footprint and increased pin count.
Q: Are both components manufactured by the same company?
A: Yes. Both the MSH222SF-CEC and MSH225SF-CDC are manufactured by MoSys, Inc., ensuring design consistency and technical support alignment.
Q: Do both components support the same interface standard?
A: Yes. Both components comply with IEEE 802.3 standards for retimer interface applications.
Q: What is the primary functional difference between these components?
A: The MSH222SF-CEC provides quad full-duplex retiming, while the MSH225SF-CDC provides 10-lane full-duplex retiming capability. The increased lane count is reflected in the larger 256-FCBGA package.
Q: Are the moisture sensitivity requirements identical?
A: Yes. Both components maintain MSL 4 (72 Hours) classification, requiring identical handling and storage protocols.
Q: Why is the MSH222SF-CEC classified as obsolete?
A: The MSH222SF-CEC has reached end-of-life status. The MSH225SF-CDC represents the active product line continuation from MoSys, Inc. for retimer interface applications.
Q: What mounting technology do both components use?
A: Both components utilize Surface Mount technology with BGA packaging, compatible with standard PCB assembly processes.
