Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PEX8624-BB50RBC F is determined by strict alignment of the following critical parameters:

• Identical package type: 324-FCBGA (19x19)
• Identical mounting type: Surface Mount
• Identical application category: PCI Express® Interface
• Identical series designation: ExpressLane™
• Identical base product number: PEX8624
• Identical MSL rating: 4 (72 Hours)
• Identical regulatory compliance: REACH Unaffected, ECCN 5A991B1, HTSUS 8542.39.0001

The substitute part PEX8624-BB50RBC G meets all substitution criteria. The revision letter change from F to G represents a product iteration within the same electrical and mechanical specifications, maintaining full compatibility with existing designs.

Parameter Comparison

Engineering Selection Recommendations

The PEX8624-BB50RBC G is the direct substitute for the obsolete PEX8624-BB50RBC F. Selection of the G revision is supported by the following factors:

• Identical electrical and mechanical specifications across all provided parameters
• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance of the substitute part exceeds regulatory requirements for modern applications
• Both parts maintain identical MSL ratings and handling requirements
• Regulatory classifications (ECCN, HTSUS) remain unchanged, simplifying compliance documentation

The transition from F to G revision represents a standard product lifecycle update within the PEX8624 base product family, with no functional or interface changes.

Frequently Asked Questions (FAQ)

Q: Can PEX8624-BB50RBC G be used as a direct replacement for PEX8624-BB50RBC F?

A: Yes. Both parts share identical package geometry (324-FCBGA 19x19), mounting type, electrical category, and functional specifications. The revision change from F to G does not alter pin configuration, electrical performance, or mechanical compatibility.

Q: What is the significance of the revision letter change from F to G?

A: The revision letter indicates a product iteration. In this case, the G revision maintains full compatibility with designs using the F revision while offering the advantage of active product status and ROHS3 compliance certification.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts carry identical MSL ratings of 4 (72 Hours), requiring the same moisture control and storage protocols during handling and assembly.

Q: Does the ROHS3 compliance of the G revision affect compatibility?

A: No. ROHS3 compliance is a material composition standard that does not alter electrical performance or mechanical fit. It represents an enhancement in regulatory compliance.

Q: Are there any supply chain or lead time considerations?

A: The PEX8624-BB50RBC F is obsolete. The PEX8624-BB50RBC G maintains active status, ensuring standard lead times and ongoing manufacturer support for procurement and technical documentation.

Q: Can both parts be used interchangeably in the same PCB assembly?

A: Yes. Identical package specifications, pin counts, and electrical characteristics ensure full interchangeability without design modifications or re-qualification.
