The substitute parts listed below maintain compatibility within the Signal Retimer application domain while accommodating different package configurations and product availability statuses.

Parameter Comparison

Engineering Selection Recommendations

89HT0816APZCBLGI (Renesas Electronics Corporation): This part is the manufacturer-recommended substitute from Renesas Electronics Corporation. It maintains the same Signal Retimer application classification and I2C interface specification as the main part. The 89HT0816APZCBLGI carries Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 Compliant with REACH Unaffected status. The primary design consideration is the package transition from 100-LFBGA (9x9) to 196-FCBGA (15x15), which requires PCB layout modification. The Moisture Sensitivity Level (MSL) improves from 3 to 2A, indicating enhanced moisture tolerance.

PM8535B-FEI (Microchip Technology): This part represents an alternative from a different manufacturer within the PCIe interface ecosystem. It is classified as a Fanout PCIe Switch Interface rather than a dedicated Signal Retimer, but operates within the same PCI Express series. The PM8535B-FEI maintains Active product status and ROHS3 Compliance. The ECCN classification differs (5A991B1 versus EAR99), which may affect export and regulatory considerations. This part is supplied in Module packaging, requiring evaluation of form factor compatibility with the original 100-LFBGA footprint.

Frequently Asked Questions (FAQ)

Q: Why is the 89HT0808PYDABGI classified as Obsolete? A: The 89HT0808PYDABGI has reached end-of-life status with Renesas Electronics Corporation. Substitute parts must be identified for new designs or legacy system maintenance.

Q: What is the primary difference between the 89HT0816APZCBLGI and the main part? A: The 89HT0816APZCBLGI uses a larger 196-FCBGA (15x15) package compared to the 100-CABGA (9x9) package of the 89HT0808PYDABGI. Both maintain Signal Retimer functionality and I2C interface compatibility. PCB layout redesign is required to accommodate the larger footprint.

Q: Can the PM8535B-FEI be used as a direct replacement? A: The PM8535B-FEI operates within the PCI Express interface category but is specified as a Fanout PCIe Switch rather than a dedicated Signal Retimer. Application-level compatibility must be evaluated based on system requirements. The Module packaging differs from the BGA format of the original part.

Q: Are all substitute parts RoHS compliant? A: Yes. Both substitute parts are ROHS3 Compliant, matching the compliance status of the 89HT0808PYDABGI.

Q: What are the moisture sensitivity considerations? A: The 89HT0808PYDABGI has MSL 3 (168 Hours). The 89HT0816APZCBLGI improves to MSL 2A (4 Weeks), providing better moisture tolerance. The PM8535B-FEI has MSL 4 (72 Hours), indicating lower moisture tolerance and requiring more stringent handling during storage and assembly.

Q: Do the substitute parts have different export classifications? A: The 89HT0816APZCBLGI maintains the same ECCN classification (EAR99) as the main part. The PM8535B-FEI uses ECCN 5A991B1, which may have different export control implications depending on destination and end-use.
