Key Parameters

Substitute Part Grouping Explanation

Substitution for the 80KSW0004ARI is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Manufacturer: Renesas Electronics Corporation (same manufacturer ensures design compatibility and support continuity)
• Product Category: Serial RapidIO® Switch or compatible packet switching interface
• Interface Technology: RapidIO protocol support
• Mounting Type: Surface Mount (consistent with original design)
• MSL Rating: 4 (72 Hours) or equivalent (ensures compatible handling requirements)

Secondary Considerations:

• Product Status: Active status preferred for long-term availability
• RoHS Compliance: ROHS3 Compliant status preferred for regulatory alignment
• REACH Status: REACH Unaffected (consistent with original)

The 80RXS1632AALGI qualifies as a manufacturer-recommended substitute based on these parameters. While it features a larger package footprint (784-FCBGA 29x29 versus 324-FCBGA 19x19), it maintains the same manufacturer, RapidIO protocol support, surface mount technology, and MSL rating. The part is currently active and RoHS3 compliant, providing superior long-term availability and regulatory compliance compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The 80RXS1632AALGI is the manufacturer-recommended substitute for the 80KSW0004ARI. Selection of this part is justified by the following factors:

1. Manufacturer Continuity: Both parts are manufactured by Renesas Electronics Corporation, ensuring consistent design philosophy, support infrastructure, and technical documentation availability.

2. Product Status Advantage: The 80RXS1632AALGI holds active product status, guaranteeing long-term availability, continued manufacturing support, and access to technical resources. The original 80KSW0004ARI is obsolete and subject to discontinuation of support services.

3. Regulatory Compliance: The 80RXS1632AALGI achieves ROHS3 compliance, aligning with current environmental and regulatory requirements. The original part is RoHS non-compliant, which may present procurement and deployment restrictions in regulated markets.

4. Handling Compatibility: Both parts maintain identical MSL ratings (4, 72 Hours), ensuring compatible storage, handling, and assembly processes without modification to existing manufacturing procedures.

5. Protocol Compatibility: Both parts support RapidIO switching functionality, maintaining functional equivalence for wireless infrastructure applications.

Design Consideration: The substitute part features a larger package footprint (784-FCBGA 29x29 versus 324-FCBGA 19x19). PCB layout modifications are required to accommodate the increased package size. This represents the primary design change necessary for implementation.

Frequently Asked Questions (FAQ)

Q: Why is the 80RXS1632AALGI recommended as a substitute for the 80KSW0004ARI?

A: The 80RXS1632AALGI is the manufacturer-recommended substitute from Renesas Electronics Corporation. Both parts share the same manufacturer, RapidIO protocol support, surface mount technology, and MSL rating. The substitute part offers the additional advantages of active product status and ROHS3 compliance, addressing the obsolescence and regulatory limitations of the original part.

Q: What is the primary design change required when implementing the 80RXS1632AALGI as a substitute?

A: The substitute part uses a 784-FCBGA (29x29) package compared to the original 324-FCBGA (19x19) package. This larger footprint requires PCB layout redesign to accommodate the increased component size and ball grid array dimensions. All other electrical and mechanical interfaces remain compatible with the original design requirements.

Q: Are the handling and storage requirements identical between the two parts?

A: Yes. Both the 80KSW0004ARI and 80RXS1632AALGI maintain the same MSL rating of 4 (72 Hours). This ensures that existing storage, handling, and assembly procedures require no modification. Standard surface mount assembly processes are applicable to both parts without additional environmental controls.

Q: Does the substitute part support the same RapidIO protocol as the original?

A: Yes. Both parts are RapidIO-based switching components manufactured by Renesas Electronics Corporation. The 80RXS1632AALGI is specifically designed as a packet switch with RapidIO interface support, maintaining functional compatibility with the original 80KSW0004ARI for wireless infrastructure applications.

Q: What regulatory advantages does the 80RXS1632AALGI provide?

A: The 80RXS1632AALGI achieves ROHS3 compliance, whereas the original 80KSW0004ARI is RoHS non-compliant. This compliance status is essential for deployment in regulated markets and ensures alignment with current environmental directives. Both parts maintain REACH Unaffected status.

Q: Is the 80RXS1632AALGI currently available for procurement?

A: Yes. The 80RXS1632AALGI holds active product status with Renesas Electronics Corporation, ensuring ongoing manufacturing and availability. The original 80KSW0004ARI is obsolete and subject to limited availability and discontinued support.
