Procurement Notes
This component is officially classified as obsolete and is no longer manufactured by Vishay Electro-Films. Procurement should focus on identifying verified substitute part numbers or alternative sources that provide equivalent electrical specifications. Verify RoHS3 compliance and package dimensions when sourcing replacements to ensure mechanical compatibility.
Selection Notes
Select this component only if the specific 0.7 pF capacitance and 50 V breakdown rating align with design requirements. Consider the 0402 footprint constraints and the -55°C to +125°C operating temperature range. Due to its obsolescence, evaluate replacement options that maintain the same silicon thin-film technology and high-frequency characteristics.
Part Context
The RFCS04027000DBTT1 belongs to the RFCS series of silicon capacitors produced by Vishay Electro-Films. This series is engineered for high-performance radio frequency applications, leveraging thin-film technology on silicon substrates to achieve superior stability and quality factors compared to traditional ceramic capacitors in the microwave spectrum.
Replacement Considerations
The RFCS04027000DBTT1 is obsolete. No specific substitute part numbers are confirmed in the provided documentation. Evaluate alternatives based on identical capacitance, tolerance, voltage rating, and package size.
