PCI2050PDV Equivalent & Substitute Parts

Part Overview

The PCI2050PDV is a PCI-to-PCI Bridge Interface IC manufactured by Texas Instruments in a 208-LQFP package. This component facilitates communication between PCI bus segments, enabling bridge functionality in legacy and modern computing architectures. The part is currently classified as obsolete, making identification of suitable alternatives essential for ongoing system support, redesigns, and inventory management. Substitute parts must maintain functional equivalence in PCI bridging capability while accommodating modern packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCI2050PDV are identified based on the following critical parameters:

Direct Functional Substitutes maintain identical or equivalent electrical specifications:

• Interface protocol compatibility (PCI or PCI Express)
• Supply voltage range (3V ~ 3.6V or 3.3V nominal)
• Package form factor and pin count
• Surface mount assembly compatibility
• Bridge or switching interface functionality

PCI2050BPDV qualifies as a direct substitute due to identical electrical specifications, package type, and functional application. The primary distinction is product status (Active vs. Obsolete) and packaging format (Tray vs. unspecified).

89HPES24N3A2ZCBX8 represents a manufacturer-recommended alternative from Renesas Electronics Corporation. While this part operates on PCI Express rather than legacy PCI, it provides equivalent switching and interface functionality. The transition from 208-LQFP to 420-SBGA packaging and the shift from PCI to PCI Express reflect modern architectural evolution. Supply voltage remains compatible at 3.3V nominal operation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: PCI2050BPDV is the preferred substitute when maintaining legacy PCI architecture. This part carries Active product status, ensuring continued availability and support. Both parts maintain ROHS3 compliance and identical electrical specifications, enabling drop-in replacement with no circuit redesign required.

For System Modernization: 89HPES24N3A2ZCBX8 is suitable when transitioning to PCI Express architecture. This part is actively manufactured by Renesas Electronics Corporation and supports modern switching interface applications. Selection of this alternative requires PCB redesign due to package change from 208-LQFP to 420-SBGA and necessitates compliance review due to RoHS non-compliance status. The increased moisture sensitivity level (MSL 4) requires controlled storage and handling procedures during assembly.

Compliance Considerations: Both Texas Instruments substitutes maintain ROHS3 compliance. The Renesas alternative does not meet RoHS requirements and must be evaluated against system-level compliance mandates before selection.

Frequently Asked Questions (FAQ)

Q: Can PCI2050BPDV replace PCI2050PDV without circuit modification? A: Yes. PCI2050BPDV maintains identical electrical specifications, package type, pin count, and functional application. Direct substitution is possible without PCB redesign.

Q: What is the primary difference between PCI2050PDV and PCI2050BPDV? A: Product status and packaging format. PCI2050BPDV is Active (currently manufactured), while PCI2050PDV is Obsolete. PCI2050BPDV is supplied in Tray packaging.

Q: When should 89HPES24N3A2ZCBX8 be selected over PCI2050BPDV? A: When system architecture requires PCI Express interface capability or when Renesas component qualification is mandated. This selection requires PCB redesign due to package change.

Q: What are the package differences between these parts? A: PCI2050PDV and PCI2050BPDV both use 208-LQFP (208-QFP 28x28). The 89HPES24N3A2ZCBX8 uses 420-SBGA (420-SBGA 27x27), requiring different PCB layout and assembly processes.

Q: Are there supply voltage compatibility issues between these parts? A: PCI2050PDV and PCI2050BPDV operate at 3V ~ 3.6V. The 89HPES24N3A2ZCBX8 operates at 3.3V nominal. All three parts are compatible with standard 3.3V supply rails.

Q: What does Moisture Sensitivity Level (MSL) mean for component handling? A: MSL indicates maximum exposure time to moisture before assembly. PCI2050PDV and PCI2050BPDV have MSL 1 (unlimited exposure). The 89HPES24N3A2ZCBX8 has MSL 4, requiring storage in dry conditions and baking before reflow soldering if exposed to humidity.

Q: Is RoHS compliance a factor in selecting between these parts? A: Yes. PCI2050PDV and PCI2050BPDV are ROHS3 compliant. The 89HPES24N3A2ZCBX8 is RoHS non-compliant and must be evaluated against system-level environmental and regulatory requirements.
