Equivalent & Substitute Parts for Renesas 80KSW0004AR Serial RapidIO® Switch

Part Overview

The Renesas 80KSW0004AR is a Serial RapidIO® Switch integrated circuit in a 324-FCBGA (19x19) package configuration. This component is classified as obsolete, indicating it has reached end-of-life status and is no longer in active production. The part is designed for wireless infrastructure applications requiring serial RapidIO® switching functionality with surface mount deployment.

Due to its obsolete product status, sourcing new inventory from primary distribution channels is limited. Organizations currently utilizing this component must evaluate equivalent alternatives to ensure continuity of supply for new designs or replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 80KSW0004AR is determined by the following critical parameters:

Functional Compatibility: Both the main part and substitute must operate as Serial RapidIO® Switches, maintaining the same protocol and switching architecture.

Mounting Technology: Surface mount deployment is required for both components to ensure compatibility with existing PCB assembly processes.

Manufacturer Consistency: Renesas Electronics Corporation manufactures both the original and substitute components, ensuring design continuity and technical support alignment.

Environmental Compliance: Moisture sensitivity level (MSL 4, 72 Hours) is maintained across both components, requiring identical handling and storage protocols.

Package Consideration: While the substitute part uses a larger 784-FCBGA (29x29) package compared to the original 324-FCBGA (19x19), both are FCBGA package families suitable for high-density interconnection applications.

The primary distinction between these components is the package size and pin count, which reflects different switching capacity and application scope within the Serial RapidIO® product line.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 80RXS1632AALG substitute part maintains active product status with Renesas Electronics Corporation, ensuring ongoing technical support, documentation availability, and supply chain stability. The original 80KSW0004AR has reached obsolete status, limiting future sourcing options.

Regulatory Compliance: The substitute part 80RXS1632AALG achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The original part is RoHS non-compliant, which may present regulatory constraints for new product designs or deployments in regions with strict RoHS enforcement.

Environmental Handling: Both components share identical Moisture Sensitivity Level (MSL 4, 72 Hours) specifications, requiring equivalent storage, handling, and reflow processing protocols.

Package Architecture: The transition from 324-FCBGA to 784-FCBGA represents an increase in pin count and package footprint. Design integration requires PCB layout modification and potential changes to board space allocation. Both packages utilize FCBGA technology, maintaining compatibility with standard surface mount assembly equipment and processes.

Supply Chain Availability: The substitute part demonstrates higher current inventory levels (1167 Pcs) compared to the original part's remaining stock (799 Pcs), supporting long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the 80RXS1632AALG directly replace the 80KSW0004AR without PCB modifications?

A: No. The substitute part uses a 784-FCBGA (29x29) package compared to the original 324-FCBGA (19x19) package. PCB layout redesign is required to accommodate the larger footprint and increased pin count. The ball grid array pitch and interconnection pattern differ between these package sizes.

Q: What is the primary reason for substitution?

A: The 80KSW0004AR has reached obsolete product status. The 80RXS1632AALG is an active product from the same manufacturer, ensuring continued availability, technical support, and regulatory compliance.

Q: Are the moisture sensitivity requirements identical?

A: Yes. Both components specify Moisture Sensitivity Level 4 with a 72-hour floor life. Identical handling, storage, and reflow protocols apply to both parts.

Q: Does the substitute part meet current environmental regulations?

A: The 80RXS1632AALG achieves ROHS3 compliance, meeting current hazardous substance restrictions. The original part is RoHS non-compliant and may not satisfy regulatory requirements for new designs.

Q: What are the implications of the larger package size?

A: The 784-FCBGA package is physically larger (29x29mm versus 19x19mm) and contains more pins than the original 324-FCBGA package. This requires board space reallocation and updated assembly documentation. Both packages are FCBGA technology and compatible with standard surface mount manufacturing processes.

Q: Are both parts manufactured by the same company?

A: Yes. Both the 80KSW0004AR and 80RXS1632AALG are manufactured by Renesas Electronics Corporation, ensuring design consistency and technical alignment.

Q: What is the REACH and ECCN status of the substitute part?

A: The 80RXS1632AALG maintains REACH Unaffected status, identical to the original part. The ECCN classification changes from 5A991B1 to EAR99, reflecting updated export control categorization.
