PCI1620PDV Equivalent & Substitute Parts

Part Overview

The PCI1620PDV is a PCI CardBus Controller designed for PC Card 8.0 interface applications, manufactured by Texas Instruments in a 208-LQFP package. This component functions as a dual-socket controller for PCI interface connectivity. The product is currently classified as Obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the PCI1620PDV is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 208-LQFP package format (208-QFP 28x28 dimensions) to ensure mechanical and electrical fit in existing PCB layouts.

Protocol & Interface Alignment: The substitute must support PCI CardBus protocol and PCI interface standard to maintain functional compatibility with host systems.

Voltage Supply Range: The substitute voltage specifications must encompass or be compatible with the system's power delivery requirements. The PCI1620PDV operates across 1.8V to 5V.

Regulatory Compliance: Both parts must maintain equivalent RoHS and REACH compliance status to satisfy procurement and environmental requirements.

The identified substitute part, PCI1520PDV, meets these core substitution criteria while operating under a different PC Card standard (PC Card 7.1 versus PC Card 8.0) and with a narrower voltage range (3.3V, 5V).

Parameter Comparison

Engineering Selection Recommendations

The PCI1520PDV serves as the manufacturer-recommended substitute for the obsolete PCI1620PDV. Both components share identical package specifications (208-LQFP), regulatory compliance status (ROHS3 Compliant, REACH Unaffected), and moisture sensitivity ratings, ensuring compatibility at the mechanical and environmental levels.

The PCI1520PDV maintains Last Time Buy status, indicating continued availability for procurement, whereas the PCI1620PDV is classified as Obsolete. Selection of the PCI1520PDV is appropriate for new designs or system refreshes requiring PC Card 7.1 standard support.

Voltage supply differences require verification: the PCI1620PDV supports 1.8V to 5V operation, while the PCI1520PDV is specified for 3.3V and 5V operation. System designs operating at 1.8V supply voltage cannot use the PCI1520PDV as a direct substitute without additional power management considerations.

Frequently Asked Questions (FAQ)

Q: Can the PCI1520PDV directly replace the PCI1620PDV in existing designs?

A: Direct replacement is possible from a package and mechanical standpoint, as both use the 208-LQFP format. However, voltage supply compatibility must be verified. If your system operates at 1.8V, the PCI1520PDV is not suitable. Systems using 3.3V or 5V supplies are compatible.

Q: What is the difference between PC Card 8.0 and PC Card 7.1 standards?

A: The PCI1620PDV implements PC Card 8.0 standard, while the PCI1520PDV implements PC Card 7.1. This represents a difference in the PC Card specification version supported by each controller. Compatibility depends on your system's PC Card slot and peripheral requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the PCI1620PDV and PCI1520PDV are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Why is the PCI1620PDV classified as Obsolete?

A: The Obsolete status indicates the part is no longer in active production. The PCI1520PDV, classified as Last Time Buy, represents the current alternative for new procurement and system designs.

Q: What packaging options are available for the PCI1520PDV?

A: The PCI1520PDV is supplied in Tray packaging, whereas the PCI1620PDV packaging specification was not provided. Confirm packaging requirements with your procurement process.

Q: Are there additional substitute options beyond the PCI1520PDV?

A: The PCI1520PDV is the manufacturer-recommended substitute. The PCI1520PDV documentation references additional parts (PCI1420PDVG4, PCI1420PDV) in its substitute chain, but these are not direct equivalents to the PCI1620PDV and require separate compatibility analysis.
