Substitute Part Grouping Explanation

Substitution eligibility for the PCI1420PDV is determined by the following critical parameters:

Primary Substitution Criteria:

• Protocol compatibility: PCI CardBus
• Function: Controller
• Interface: PCI
• Package / Case: 208-LQFP
• Voltage Supply: 3.3V and 5V dual voltage operation
• Supplier Device Package: 208-QFP (28x28)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The PCI1520PDV qualifies as a manufacturer-recommended substitute based on matching all primary substitution criteria. Both devices share identical electrical specifications, package geometry, and compliance certifications. The PCI1520PDV provides enhanced functionality through PC Card 7.1 standards support and defined operating temperature range (0°C ~ 70°C), while maintaining full backward compatibility with the PCI1420PDV interface requirements.

Parameter Comparison

Engineering Selection Recommendations

For PCI1420PDV Replacement:

The PCI1520PDV is the manufacturer-recommended substitute and is qualified for direct replacement in applications currently using the PCI1420PDV. Both devices maintain identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence.

Compliance Considerations:

Both the PCI1420PDV and PCI1520PDV meet ROHS3 compliance requirements and are REACH unaffected, supporting continued use in regulated markets. The MSL rating of 1 (Unlimited) for both devices indicates no moisture sensitivity constraints during storage or handling.

Product Status Impact:

Given the Last Time Buy status of both devices, long-term availability should be evaluated during design planning. Procurement of substitute inventory should align with production schedules and end-of-life timelines established by Texas Instruments.

Frequently Asked Questions (FAQ)

Q: Can the PCI1520PDV be used as a direct replacement for the PCI1420PDV?

A: Yes. The PCI1520PDV is the manufacturer-recommended substitute. Both devices share identical package geometry (208-LQFP, 28x28mm), voltage specifications (3.3V and 5V), and PCI CardBus protocol implementation, ensuring functional compatibility.

Q: What are the key differences between PCI1420PDV and PCI1520PDV?

A: The PCI1520PDV includes PC Card 7.1 standards support and specifies an operating temperature range of 0°C ~ 70°C. The PCI1420PDV does not list these specifications. Both devices are electrically and mechanically equivalent for PCI CardBus controller applications.

Q: Are there any package or pinout differences?

A: No. Both devices use the 208-LQFP package with 28x28mm dimensions. Pinout and mechanical footprint are identical, supporting direct PCB layout compatibility.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments will no longer manufacture these devices after a specified date. Customers requiring these parts should plan procurement accordingly and consider long-term inventory strategies.

Q: Do both devices meet current compliance standards?

A: Yes. Both the PCI1420PDV and PCI1520PDV are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Is there a difference in moisture sensitivity between the two devices?

A: No. Both devices have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during standard storage and handling conditions.
