Replacement verdict
Compatible functional replacement candidate
The 8535AG-31LFT and 8535AGI-01LFT are functionally compatible clock fanout buffers with matching logic type, supply voltage, and package footprint, differing primarily in output frequency capability and operating temperature range. The 8535AGI-01LFT offers a higher maximum output frequency and an extended industrial temperature range, making it a viable replacement for the 8535AG-31LFT in most applications, provided the target design does not require the lower frequency variant's specific configuration.

Key electrical and mechanical differences between the two devices
| Parameter | 8535AG-31LFT | 8535AGI-01LFT | Why it matters |
|---|---|---|---|
| Manufacturer Part Number | 8535AG-31LFT | 8535AGI-01LFT | Identifies the exact orderable variant; the -31 and -01 suffixes denote different device configurations and cannot be treated as interchangeable. |
| Function / Device Type | Clock fanout buffer / clock distribution | Clock generator / clock synthesizer | A buffer distributes an existing clock, while a generator synthesizes clocks from a reference; these are functionally different roles and are not drop-in substitutes. |
| Input Type | Differential clock input (e.g., LVPECL/LVDS/HCSL/CML) | Crystal or reference clock input | The input interface determines what source signal the device can accept, directly affecting board-level compatibility. |
| Output Type | LVPECL | LVPECL | Output logic level must match the receiving device's input requirements for reliable signal integrity. |
| Number of Outputs | 4 | 4 | Output count determines how many loads can be driven without additional buffering. |
| Supply Voltage | 3.3 V | 3.3 V | Supply voltage must match the system rail; a mismatch can damage the device or prevent proper operation. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The temperature range defines the environments in which the part can be reliably used; industrial and commercial grades differ. |
| Package / Case | TSSOP-20 | TSSOP-20 | Package footprint and pinout must match the PCB layout for physical and electrical compatibility. |
| Packaging | Tape & Reel | Tape & Reel | Packaging form affects assembly line handling and reflow processes; both being tape and reel supports automated placement. |
| RoHS Compliance | RoHS compliant | RoHS compliant | RoHS status is required for regulatory compliance in many markets and affects solderability and material declarations. |
