Procurement Notes

This component is officially obsolete and no longer manufactured by Vishay Electro-Films. Procurement must focus on verified substitute part numbers from authorized distributors. Verify that replacement components match the original electrical specifications, including capacitance, voltage rating, and package dimensions, to ensure circuit compatibility.

Selection Notes

Selection should prioritize substitutes that maintain the 12 pF capacitance and 16 V rating within the 0402 footprint. Ensure the replacement supports the required -55°C to +125°C operating range. Verify RoHS compliance and MSL ratings if moisture sensitivity is critical for the assembly process.

Part Context

The RFCS series represents Vishay's line of silicon-based capacitors, offering advantages over traditional ceramic types in terms of stability and low parasitic inductance. This specific model belongs to the RFCS family, optimized for radio frequency and microwave applications requiring precise capacitance values in compact surface-mount packages.

Replacement Considerations

The KYOCERA AVX part number 0402ZK220GBSTR is listed as a similar substitute. Verify electrical equivalence before adoption.
