PCI1520IGHKEP PC Card Controller Equivalent & Substitute Parts

Part Overview

The PCI1520IGHKEP is a PCI CardBus Controller designed for PC Card 7.1 interface applications with dual voltage supply support (3.3V, 5V). This component operates across the industrial temperature range of -40°C to 85°C and is packaged in a 209-BGA MICROSTAR format.

The PCI1520IGHKEP carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing system support. Substitute parts must maintain identical protocol, interface, and electrical specifications while accommodating different packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCI1520IGHKEP is determined by the following critical parameters:

• Base Product Number: Must be PCI1520 (ensures identical core controller architecture)
• Protocol: Must be PCI CardBus (maintains system-level compatibility)
• Interface: Must be PCI (ensures host system compatibility)
• Standards: Must be PC Card 7.1 (guarantees card slot compatibility)
• Voltage Supply: Must support 3.3V and 5V (ensures power delivery compatibility)
• Operating Temperature Range: Must be -40°C ~ 85°C (maintains thermal specifications)
• Compliance: Must maintain ROHS3 and REACH Unaffected status

The PCI1520IPDVEP qualifies as a direct substitute based on these parameters. While the package format differs (208-LQFP versus 209-BGA), the electrical and functional specifications remain identical, allowing for substitution in applications where the alternative package footprint can be accommodated.

Parameter Comparison

Engineering Selection Recommendations

The PCI1520IPDVEP serves as the manufacturer-recommended substitute for the obsolete PCI1520IGHKEP. Both components share identical electrical specifications, protocol support, and compliance certifications (ROHS3, REACH Unaffected).

The primary design consideration is package format: the PCI1520IGHKEP uses a 209-BGA MICROSTAR package, while the PCI1520IPDVEP uses a 208-LQFP package. PCB layout and assembly process compatibility must be evaluated based on your manufacturing capabilities.

The PCI1520IPDVEP carries a Last Time Buy status, indicating limited availability. Inventory planning should account for this constraint when selecting this substitute for new production runs.

The MSL rating difference (3 versus 1) reflects improved moisture handling in the LQFP package. This provides a secondary advantage for applications requiring extended storage or humid environment exposure.

Frequently Asked Questions (FAQ)

Q: Can the PCI1520IPDVEP directly replace the PCI1520IGHKEP on existing PCBs?

A: Direct PCB replacement is not possible due to package format differences. The PCI1520IGHKEP uses a 209-BGA footprint while the PCI1520IPDVEP uses a 208-LQFP footprint. PCB redesign is required.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts support PCI CardBus protocol, PC Card 7.1 standards, dual voltage supply (3.3V, 5V), and the same operating temperature range (-40°C ~ 85°C).

Q: What is the significance of the different MSL ratings?

A: The PCI1520IGHKEP has MSL 3 (168 hours maximum floor life), while the PCI1520IPDVEP has MSL 1 (unlimited floor life). The LQFP package provides superior moisture resistance, reducing handling and storage constraints.

Q: Are both parts still available for purchase?

A: The PCI1520IGHKEP is Obsolete. The PCI1520IPDVEP carries Last Time Buy status, indicating limited remaining inventory. Both parts have discontinued production.

Q: Do these parts maintain the same compliance certifications?

A: Yes. Both are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.
