Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8430S10AYILF is determined by the following critical parameters:

• Package Compatibility: Both parts must use 48-TQFP Exposed Pad (7x7mm) surface mount packaging to ensure PCB footprint and thermal management compatibility.
• Voltage Supply Range: The substitute must operate within or encompass the 3.135V ~ 3.465V supply voltage specification.
• Frequency Capability: The substitute must support operation at or above 133.33MHz maximum frequency.
• PLL Functionality: The substitute must include integrated PLL functionality for clock generation and distribution.
• Mounting Type: Surface mount technology must be maintained for manufacturing process compatibility.
• Environmental Compliance: REACH and ECCN classifications must align with regulatory requirements.

The 8430S10BYI-03LF meets these substitution criteria as an active Renesas Electronics clock generator in the identical 48-TQFP package with equivalent electrical specifications.
