Key Parameters

Substitute Part Grouping Explanation

Substitution of the 840S07BYILF is determined by alignment across the following critical parameters:

Functional Category: Both the main part and substitute must operate within the Clock/Timing category as frequency synthesizer or clock management integrated circuits.

Manufacturer Continuity: Renesas Electronics Corporation maintains design compatibility and technical support consistency.

Supply Voltage Compatibility: The substitute must operate within or encompass the 3.135V ~ 3.465V supply range to ensure direct integration into existing power distribution networks.

Environmental Compliance: Both parts must maintain ROHS3 compliance, REACH unaffected status, and equivalent Moisture Sensitivity Level (MSL 3) to satisfy regulatory and reliability requirements.

Package Compatibility: Surface mount packaging with compatible footprint dimensions supports direct PCB integration without redesign.

The substitute part RC31008A000GND#BB0 is identified as a manufacturer-recommended equivalent based on these alignment criteria.
