Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P9261-BNLG28 are identified based on the following critical parameters that determine functional and physical compatibility:

Primary Substitution Criteria:

• Shared Base Product Number (P9261)
• Identical Manufacturer (Renesas Electronics Corporation)
• Matching Functional Category (Power Management PMIC)
• Active Product Status (ensuring ongoing availability and support)

The P9261-3CNLG28 qualifies as a substitute part because it maintains the same base product lineage and manufacturer origin while offering an active, supported alternative. Both parts belong to the P9261 product family, ensuring design compatibility at the functional level. The substitute part features an Active product status, providing long-term availability and manufacturer support, which is critical for production continuity.

Engineering Selection Recommendations

For New Designs and Production Continuity:

The P9261-3CNLG28 is the designated substitute for the obsolete P9261-BNLG28. Selection of the substitute part is based on the following engineering factors:

1. Product Status Alignment: The substitute part maintains Active product status, ensuring manufacturer support, continued availability, and compliance with current supply chain requirements. The original part's Obsolete designation eliminates it as a viable option for new production.

2. Regulatory Compliance: The P9261-3CNLG28 carries REACH Unaffected status and EAR99 ECCN classification, providing clear regulatory standing for international distribution and use. These certifications support compliance with export control and environmental regulations.

3. Manufacturer Continuity: Both parts originate from Renesas Electronics Corporation, maintaining design lineage and ensuring technical support consistency through the same manufacturer ecosystem.

4. Inventory Availability: The substitute part demonstrates adequate stock levels (883 Pcs), supporting immediate procurement and production scheduling requirements.

Frequently Asked Questions (FAQ)

Q: Why is the P9261-BNLG28 listed as Obsolete?

A: The P9261-BNLG28 has reached end-of-life status with Renesas Electronics Corporation. The manufacturer has discontinued production and technical support for this component. Obsolete designation indicates that new inventory from the manufacturer is no longer available, though existing stock may remain in distribution channels.

Q: What is the primary difference between the P9261-BNLG28 and P9261-3CNLG28?

A: The P9261-3CNLG28 is an active product variant within the same P9261 base product family. The substitute part specifies a 48-VFQFN (7x7) package with exposed pad, surface mount configuration, and wettable flank mounting type. The original part's packaging details were not provided in available documentation.

Q: Can the P9261-3CNLG28 be used as a direct replacement in existing designs?

A: The P9261-3CNLG28 shares the same base product number and manufacturer as the original part, establishing functional compatibility within the P9261 product family. However, physical package specifications must be verified against the original design requirements, particularly regarding the 48-VFQFN (7x7) package footprint and exposed pad configuration.

Q: What is the significance of the 48-VFQFN package specification?

A: The 48-VFQFN (Very Fine Pitch Quad Flat No-lead) package indicates a surface mount component with 48 pins in a 7x7 millimeter footprint. The exposed pad provides thermal management capability. This package type is standard for modern PMIC applications requiring compact form factors and efficient heat dissipation.

Q: Are there any regulatory or compliance considerations when switching to the substitute part?

A: The P9261-3CNLG28 carries REACH Unaffected status and EAR99 ECCN classification, indicating compliance with environmental and export control regulations. These certifications support use in regulated markets and international applications without additional compliance barriers.

Q: What does "REACH Unaffected" mean?

A: REACH Unaffected status indicates that the component is not subject to the European Union's Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation. This simplifies compliance documentation for designs intended for European markets.

Q: How should the transition from the obsolete part to the substitute be managed?

A: Transition planning should include verification of the 48-VFQFN (7x7) package compatibility with existing PCB layouts and assembly processes. Design documentation should be updated to reflect the substitute part number. Procurement should establish supply agreements with authorized distributors to ensure consistent availability of the P9261-3CNLG28.
