Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 89HT0808PYBABGI are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Category: Interface
• Applications: Signal Retimer or related interface functionality
• Interface Protocol: I2C or compatible protocols (PCI, PCI Express)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Product Status: Active (preferred for ongoing availability)

The substitute parts listed below meet these criteria while offering active product status, ensuring long-term component availability and supply chain reliability. Substitutes vary in package configurations (196-FCBGA, 100-QFP, 160-QFP, 272-BGA, 18-X2QFN) and specific interface protocols, reflecting different application requirements within the interface IC category.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 89HT0816APZCBLGI

The 89HT0816APZCBLGI is the manufacturer-recommended substitute from Renesas Electronics Corporation. This part maintains the same Signal Retimer application focus and I2C interface protocol as the original 89HT0808PYBABGI. It carries Active product status, ensuring sustained availability and supply chain support. The improved MSL rating of 2A (4 Weeks) provides superior moisture handling compared to the original MSL 3 specification. ROHS3 compliance and REACH Unaffected status confirm environmental and regulatory alignment.

Secondary Recommendations by Application:

For PCIe-specific applications, the PI3PCIE3212XUAEX (Diodes Incorporated) offers Active status with PCI Express interface capability and the most favorable MSL rating of 1 (Unlimited). This part is suitable for designs prioritizing PCIe protocol requirements.

For PCI-to-PCI Bridge applications, the PCI2250PCM (Texas Instruments) provides Active status with 3V–3.6V supply voltage specification and PCI interface protocol support.

For broader PCI interface requirements, the PCI9656-BA66BI G (Broadcom Limited) offers the largest inventory availability (18,003 Pcs) with dual voltage support (3.3V, 5V) and Active product status.

All substitute parts maintain ROHS3 compliance and Surface Mount mounting type, ensuring compatibility with existing PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Why is the 89HT0808PYBABGI classified as obsolete?

A: The 89HT0808PYBABGI has reached end-of-life status within Renesas Electronics Corporation's product portfolio. Obsolete classification indicates that the manufacturer no longer produces this component, making substitute parts necessary for new designs and legacy system support.

Q: What is the primary difference between the main part and the recommended substitute 89HT0816APZCBLGI?

A: Both parts are Signal Retimer Interface ICs from Renesas with I2C protocol support. The primary differences are package size (100-CABGA vs. 196-FCBGA), product status (Obsolete vs. Active), and MSL rating (3 vs. 2A). The 89HT0816APZCBLGI's Active status ensures continued availability and support.

Q: Can I use a smaller package substitute like the PI3PCIE3212XUAEX?

A: Package selection depends on your specific application requirements. The PI3PCIE3212XUAEX uses an 18-X2QFN (2x2) package, significantly smaller than the original 100-CABGA (9x9). This substitute is suitable only if your design supports the smaller footprint and PCIe interface protocol requirements.

Q: What does MSL rating mean, and why does it vary among substitutes?

A: Moisture Sensitivity Level (MSL) indicates how long a component can be exposed to moisture before soldering. MSL 1 (Unlimited) allows indefinite storage, while MSL 3 (168 Hours) requires soldering within 168 hours of moisture exposure. Higher MSL ratings (lower numbers) provide greater handling flexibility during assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, ensuring compliance with Restriction of Hazardous Substances regulations and environmental standards.

Q: Which substitute has the best supply availability?

A: The PCI9656-BA66BI G (Broadcom Limited) shows the highest inventory level at 18,003 Pcs New Original In Stock, followed by PI3PCIE3212XUAEX at 19,400 Pcs. Both offer excellent supply security for production environments.

Q: Do all substitutes support I2C interface protocol?

A: No. The 89HT0816APZCBLGI maintains I2C protocol support. Other substitutes use different protocols: FDC37C669-MS uses ISA Host, PCI2250PCM and PCI9656-BA66BI G use PCI, and PI3PCIE3212XUAEX uses PCI Express. Protocol selection must align with your system architecture.
