PI6C557-03BLE Equivalent & Substitute Parts
Part Overview
The PI6C557-03BLE is an Ethernet and PCI Express (PCIe) clock generator IC manufactured by Diodes Incorporated. This 16-TSSOP surface mount device generates a 200MHz output from HCSL or crystal input sources, delivering HCSL and LVDS differential outputs. The part is Active status and ROHS3 compliant, designed for high-speed serial interface applications requiring precise clock distribution.
Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Engineering Selection Recommendations
All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the PI6C557-03BLE.
For applications requiring the full -40°C to 85°C operating temperature range, select from: 557GI-03LF, 557GI-03LFT, 5V41065PGGI, or 5V41235PGGI. These parts match the primary device's extended temperature specification.
For applications limited to 0°C to 70°C operation, 557G-03LF, 5V41065PGG, 5V41065PGG8, and 5V41235PGG are qualified alternatives with reduced thermal range.
Voltage supply ranges vary across substitute families. The PI6C557-03BLE operates at 3V to 3.6V. Renesas 557G series parts accept 2.97V to 3.63V, providing broader supply tolerance. Renesas 5V41065 and 5V41235 series parts operate at 3.135V to 3.465V, a narrower range centered on 3.3V nominal supply.
All parts share identical 16-TSSOP package dimensions, output configurations (HCSL and LVDS), and functional characteristics (1:2 input:output ratio, PLL-based architecture, single circuit).
Frequently Asked Questions (FAQ)
Q: Can 557G-03LF replace PI6C557-03BLE in all applications?
A: 557G-03LF is electrically compatible but operates only to 70°C maximum. Use this part only in applications with 0°C to 70°C temperature requirements. For extended temperature range (-40°C to 85°C), select 557GI-03LF instead.
Q: What is the difference between 5V41065PGG and 5V41065PGGI?
A: Both parts are identical in electrical function and package. The difference is operating temperature range: 5V41065PGG operates 0°C to 70°C, while 5V41065PGGI extends to -40°C to 85°C. Select based on your application's thermal requirements.
Q: Are the Renesas 557G and 5V41065 series interchangeable?
A: Yes, both series are pin-compatible 16-TSSOP packages with identical output configurations and 200MHz maximum frequency. The primary difference is voltage supply range: 557G series accepts 2.97V to 3.63V, while 5V41065 series operates at 3.135V to 3.465V. Verify your power supply voltage falls within the selected part's specification.
Q: What packaging options are available for these substitutes?
A: Most parts are supplied in Tube packaging. The 5V41065PGG8 variant is available in Cut Tape (CT) format. Packaging does not affect electrical performance or pin compatibility.
Q: Do all substitutes support both HCSL and Crystal inputs?
A: The PI6C557-03BLE accepts HCSL or Crystal inputs. Renesas substitutes accept Clock or Crystal inputs. Both input types are compatible with standard clock distribution architectures.
Q: Are all parts REACH compliant?
A: Yes, all listed parts carry REACH Unaffected status, indicating no restricted substances under current REACH regulations.
