PI3325-00-BGMP Equivalent & Substitute Parts

Part Overview

The PI3325-00-BGMP is a buck switching regulator IC manufactured by Vicor Corporation, designed to deliver fixed 5V output at 20A from input voltages ranging from 14V to 42V. This surface-mount power management component operates at 7MHz switching frequency with integrated synchronous rectification and supports operating temperatures from -55°C to 120°C.

The PI3325-00-BGMP is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3325-00-BGMP are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be equivalent for substitution:

• Output Voltage and Current: Fixed 5V output at 20A
• Input Voltage Range: 14V to 42V minimum and maximum
• Switching Frequency: 7MHz operation
• Synchronous Rectification: Integrated synchronous rectifier required
• Operating Temperature Range: -55°C to 120°C
• Topology: Buck (step-down) configuration
• Mounting: Surface mount technology
• Base Product Number: PI3325 series

The PI3325-00-LGMZ meets all electrical specifications and operates within identical performance parameters. The primary difference is the package variant: 110-BLGA Module versus 110-BBGA Module, representing different land grid array configurations from the same product family.

Parameter Comparison

Engineering Selection Recommendations

Electrical Compatibility: The PI3325-00-LGMZ provides complete electrical equivalence to the PI3325-00-BGMP. Both parts deliver identical voltage regulation, current capacity, switching frequency, and thermal performance across the specified operating range.

Package Consideration: The primary distinction between these parts is the land grid array package variant. The PI3325-00-BGMP uses a 110-BBGA configuration (14.5mm × 10.5mm), while the PI3325-00-LGMZ uses a 110-BLGA configuration (14mm × 10mm). PCB layout and footprint design must accommodate the specific package geometry of the selected part.

Compliance Status: Both parts maintain RoHS compliance. The PI3325-00-LGMZ carries ROHS3 certification, representing current regulatory alignment. The PI3325-00-BGMP is RoHS Compliant under earlier standards. Both parts are classified as EAR99 for export control purposes and carry identical HTSUS commodity codes.

Product Status: Both parts are obsolete. Selection between these variants should be based on PCB design constraints and existing inventory availability rather than performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can the PI3325-00-LGMZ directly replace the PI3325-00-BGMP in existing designs?

A: Electrical substitution is complete. However, the package footprint differs between the 110-BBGA and 110-BLGA variants. PCB redesign is required to accommodate the different land grid array dimensions and pin layout. Direct socket replacement is not possible without layout modification.

Q: What is the difference between 110-BBGA and 110-BLGA packages?

A: Both are 110-pin land grid array modules from Vicor's PI3325 family. The BBGA variant measures 14.5mm × 10.5mm, while the BLGA variant measures 14mm × 10mm. The BLGA represents a slightly more compact footprint. Pin configuration and electrical connectivity remain equivalent.

Q: Are there thermal performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 120°C) and share the same switching frequency (7MHz) and output current rating (20A). Thermal performance is equivalent.

Q: What does the packaging designation "Tray" for PI3325-00-LGMZ indicate?

A: Tray packaging refers to the shipping and storage container format. This does not affect electrical performance or component functionality. It indicates the quantity and presentation method for procurement and assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. The PI3325-00-BGMP is RoHS Compliant. The PI3325-00-LGMZ carries ROHS3 Compliant certification, representing alignment with current regulatory requirements. Both parts meet RoHS standards for hazardous substance restrictions.

Q: Can these parts be used interchangeably in new designs?

A: From an electrical standpoint, yes. However, since both parts are obsolete, new designs should evaluate current-generation alternatives from Vicor Corporation's active product portfolio. If legacy design continuity is required, either part can be selected based on PCB layout compatibility and inventory availability.

Q: What is the significance of Moisture Sensitivity Level 3?

A: MSL 3 indicates these components require controlled humidity storage and handling. Components must be stored in dry conditions and have a floor life of 168 hours (7 days) after exposure to ambient humidity. Proper moisture barrier packaging and baking procedures are required before assembly.
