PCI2040GGU Equivalent & Substitute Parts

Part Overview

The PCI2040GGU is a PCI-DSP bridge controller IC manufactured by Texas Instruments, housed in a 144-BGA MICROSTAR (12x12) package. This component functions as a controller for PCI interface applications and operates across a supply voltage range of 3.3V to 5V with an operating temperature range of 0°C to 70°C. The PCI2040GGU is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the PCI2040GGU are identified based on the following critical parameters that determine functional equivalence:

• Base Product Number: Both the main part and substitute share the PCI2040 base product number, indicating they are variants of the same controller architecture
• Function: Both maintain the controller function for PCI interface applications
• Interface Type: Both implement PCI interface protocol
• Voltage Supply Range: Both operate at 3.3V and 5V supply voltages
• Operating Temperature Range: Both support 0°C to 70°C operating conditions
• Manufacturer: Both are manufactured by Texas Instruments
• Compliance Standards: Both maintain ROHS3 compliance and REACH unaffected status

The primary difference between the main part and substitute lies in the package type and product status. The PCI2040GGU uses a 144-BGA MICROSTAR (12x12) package and is obsolete, while the substitute PCI2040PGE uses a 144-LQFP (20x20) package and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The PCI2040PGE serves as the manufacturer-recommended substitute for the obsolete PCI2040GGU. Both components share identical electrical specifications, including supply voltage range (3.3V to 5V) and operating temperature range (0°C to 70°C), ensuring functional compatibility at the controller and interface level.

The PCI2040PGE maintains active product status with improved moisture sensitivity characteristics (MSL 1 versus MSL 3), providing superior reliability for long-term storage and deployment. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

The primary design consideration is the package transition from 144-BGA MICROSTAR (12x12) to 144-LQFP (20x20). This package change requires PCB layout modifications, including different footprint dimensions and pin arrangement patterns. The LQFP package occupies a larger board area (20x20mm versus 12x12mm) and uses through-hole lead technology rather than ball grid array technology.

Frequently Asked Questions (FAQ)

Q: Are the PCI2040GGU and PCI2040PGE electrically interchangeable?

A: Both components share identical electrical specifications including supply voltage (3.3V, 5V), operating temperature range (0°C to 70°C), and PCI interface protocol implementation. Electrical compatibility is confirmed. However, physical package differences require PCB redesign.

Q: What is the primary difference between these two parts?

A: The main differences are package type and product status. The PCI2040GGU uses a 144-BGA MICROSTAR (12x12) package and is obsolete. The PCI2040PGE uses a 144-LQFP (20x20) package and maintains active product status with improved moisture sensitivity (MSL 1 versus MSL 3).

Q: Can I use the PCI2040PGE as a direct replacement without PCB modifications?

A: No. The package change from BGA to LQFP requires PCB footprint redesign. The LQFP package is larger (20x20mm) and uses different pin connection technology. PCB layout modifications are mandatory.

Q: Do both parts meet current compliance standards?

A: Yes. Both the PCI2040GGU and PCI2040PGE are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What does the MSL rating difference mean for component handling?

A: The PCI2040GGU has MSL 3 (168 hours), requiring controlled moisture exposure during storage and handling. The PCI2040PGE has MSL 1 (unlimited), allowing indefinite storage without moisture control measures, providing greater handling flexibility.
