Substitute Part Grouping Explanation

Substitution eligibility for the PI7C9X7952BFDEX is determined by strict alignment of the following parameters:

• Functional Equivalence: Both components must perform PCI to UART bridge functionality
• Protocol Compatibility: PCI protocol support required
• Electrical Specifications: Identical supply voltage range (1.8V, 3.3V) and operating temperature range (-40°C ~ 85°C)
• Mechanical Compatibility: Identical package type (128-LQFP with 14x14mm dimensions)
• Compliance Requirements: ROHS3 compliance and MSL 3 rating maintained
• Packaging Format: Tape & Reel (TR) configuration

The PI7C9X7954BFDEX meets all substitution criteria, sharing identical electrical parameters, package specifications, compliance certifications, and functional classification.

Frequently Asked Questions (FAQ)

Q: Can PI7C9X7954BFDEX directly replace PI7C9X7952BFDEX in existing designs?

A: Yes. Both components share identical electrical specifications, package dimensions (128-LQFP 14x14mm), supply voltage requirements (1.8V, 3.3V), operating temperature range (-40°C ~ 85°C), and functional classification as PCI to UART bridges. Direct substitution is supported without circuit modification.

Q: Are there differences in compliance or certifications between these parts?

A: No. Both components maintain ROHS3 compliance, REACH unaffected status, and identical MSL 3 moisture sensitivity ratings. Compliance requirements are equivalent.

Q: What determines substitution eligibility for PCI to UART bridge components?

A: Substitution requires matching protocol (PCI), interface type (UART), functional classification (Bridge), package type (128-LQFP), electrical specifications (supply voltage and operating temperature), and compliance certifications (ROHS3, MSL rating).

Q: Are there any packaging or handling differences?

A: Both components are supplied in Tape & Reel (TR) format with identical MSL 3 ratings (168 hours). Handling and storage requirements are equivalent.

Q: What is the base product number relationship?

A: The PI7C9X7952BFDEX has base product number PI7C9X7952, while the PI7C9X7954BFDEX has base product number PI7C9X7954. These represent different product variants within the Diodes Incorporated PCI bridge family, both meeting identical electrical and mechanical specifications.
