Renesas Electronics P9145-00NHGI Power Management IC Equivalent & Substitute Parts

Part Overview

The Renesas Electronics P9145-00NHGI is a processor-based systems Power Management IC (PMIC) housed in a 100-VFQFN dual-row package with exposed pad. This component is classified as obsolete and is no longer in active production. The P9145-00NHGI was designed to manage power distribution and regulation in processor-based computing systems with a supply voltage range of 4.5V to 5.25V.

Due to its obsolete status, sourcing new original inventory of the P9145-00NHGI presents supply chain challenges. Identifying functionally equivalent active-production alternatives ensures design continuity and long-term component availability for new builds and system redesigns.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P9145-00NHGI is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 100-VFQFN dual-row package with exposed pad (9x9 footprint) to ensure mechanical and electrical compatibility on the PCB.

Voltage Supply Range: The substitute part must operate within a voltage supply range that encompasses or exceeds the original specification of 4.5V to 5.25V. The substitute P91E0A-00NHGI operates from 3.135V to 5.25V, which provides a wider lower-voltage capability while maintaining full compatibility at the original operating range.

Operating Temperature Range: The substitute must support the same operating temperature range of -40°C to 85°C to ensure thermal compatibility in the target application environment.

Application Category: Both parts must be classified for processor-based systems applications to confirm functional equivalence.

Compliance Standards: Both parts must maintain ROHS3 compliance and equivalent moisture sensitivity levels to ensure regulatory and manufacturing process compatibility.

Product Status Consideration: The substitute P91E0A-00NHGI is active production, ensuring long-term availability and supply chain reliability compared to the obsolete P9145-00NHGI.

Parameter Comparison

Engineering Selection Recommendations

The P91E0A-00NHGI is a direct substitute for the obsolete P9145-00NHGI based on the following engineering criteria:

Package Equivalence: Both parts use the identical 100-VFQFN (9x9) dual-row package with exposed pad. PCB layouts, footprints, and assembly processes require no modification.

Electrical Compatibility: The P91E0A-00NHGI operates across a voltage supply range of 3.135V to 5.25V, which fully encompasses the original P9145-00NHGI specification of 4.5V to 5.25V. The extended lower-voltage capability provides additional design flexibility without compromising compatibility at the original operating point.

Thermal Compatibility: Identical operating temperature range of -40°C to 85°C ensures the substitute functions across the same environmental conditions as the original part.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 3, 168 hours), ensuring compatibility with manufacturing processes and regulatory requirements.

Supply Chain Advantage: The P91E0A-00NHGI is in active production status with 1087 pieces in current inventory, compared to the obsolete P9145-00NHGI. This ensures reliable long-term availability for production builds and future system revisions.

Frequently Asked Questions (FAQ)

Q: Can the P91E0A-00NHGI be used as a direct replacement for the P9145-00NHGI without PCB modifications?

A: Yes. Both parts use the identical 100-VFQFN (9x9) package with exposed pad. No PCB layout changes, footprint adjustments, or assembly process modifications are required.

Q: What is the significance of the extended voltage range (3.135V to 5.25V) in the P91E0A-00NHGI compared to the original (4.5V to 5.25V)?

A: The substitute part operates across a wider lower-voltage range. For applications using the original 4.5V to 5.25V supply window, the P91E0A-00NHGI provides full compatibility. The extended lower-voltage capability (down to 3.135V) offers additional design flexibility for future applications without affecting existing designs.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 3, 168 hours). Manufacturing and handling processes remain unchanged.

Q: Why is the P9145-00NHGI listed as obsolete?

A: The P9145-00NHGI has been discontinued by Renesas Electronics Corporation. The P91E0A-00NHGI represents the active-production equivalent that fulfills the same functional and mechanical requirements.

Q: Is the P91E0A-00NHGI suitable for new product designs?

A: Yes. The P91E0A-00NHGI is in active production status and is the appropriate choice for new designs requiring processor-based systems power management in the 100-VFQFN package. It provides long-term supply chain stability compared to obsolete alternatives.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: identical package type (100-VFQFN 9x9), compatible voltage supply range (substitute range must encompass original), matching operating temperature range (-40°C to 85°C), identical application category (processor-based systems), and equivalent compliance standards (ROHS3, MSL 3).
