Engineering Selection Recommendations

Parametric Equivalent (Same Specifications): KGM21BCG2A220KT from KYOCERA AVX provides identical electrical and mechanical specifications to the 08051A220KAT2P. This part maintains ±10% tolerance, 100V rating, and 0805 package with equivalent performance characteristics. Selection is appropriate for direct replacement in existing designs.

Direct Equivalent (Alternative Manufacturer): C0805C220K1GAC7800 from KEMET matches all critical parameters: 22 pF capacitance, ±10% tolerance, 100V rating, C0G/NP0 temperature coefficient, and 0805 package. Both manufacturers maintain ROHS3 compliance and MSL 1 rating. This part is suitable for applications where manufacturer diversification is required.

Upgrade Options (Improved Tolerance): KGM21BCG2A220FT (±1%), KGM21BCG2A220GT (±2%), and KGM21BCG2A220JT (±5%) from KYOCERA AVX offer tighter tolerance specifications while maintaining 100V rating and 0805 package. These upgrades are applicable in circuits requiring enhanced capacitance stability. C0805C220G1GAC7800 (±2%) and C0805C220J1GAC7800 (±5%) from KEMET provide equivalent tolerance improvements from an alternative manufacturer.

Upgrade Options (Higher Voltage Rating): KGM21BCG2D220JT (±5%, 200V) and KGM21BCG2D220KT (±10%, 200V) from KYOCERA AVX provide 200V rating while maintaining 22 pF capacitance and 0805 package. C0805C220J2GAC7800 (±5%, 200V) from KEMET offers the same voltage upgrade from an alternative source. These parts are suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

All substitute parts maintain Active product status, ROHS3 compliance, and MSL 1 rating consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can KGM21BCG2A220JT replace 08051A220KAT2P in my circuit? A: Yes. KGM21BCG2A220JT is a direct substitute with identical capacitance (22 pF), voltage rating (100V), temperature coefficient (C0G/NP0), and package (0805). The ±5% tolerance is tighter than the original ±10%, making it functionally compatible. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the KYOCERA AVX and KEMET options? A: Both manufacturers provide equivalent electrical performance for the specified parameters. KYOCERA AVX parts (KGM series) and KEMET parts (C0805C series) match in capacitance, voltage, temperature coefficient, and package. Selection between manufacturers depends on supply chain requirements, inventory availability, and procurement preferences. All listed parts maintain identical compliance certifications.

Q: Can I use a 200V rated part instead of 100V? A: Yes. KGM21BCG2D220JT and KGM21BCG2D220KT (KYOCERA AVX) and C0805C220J2GAC7800 (KEMET) provide 200V rating with the same 22 pF capacitance and 0805 package. Higher voltage rating does not degrade performance in 100V applications and provides additional voltage margin. All parameters remain compatible.

Q: Does tolerance affect interchangeability? A: Tolerance affects capacitance accuracy but not interchangeability. The original part specifies ±10% tolerance. Substitute parts with ±1%, ±2%, or ±5% tolerance are tighter specifications and are fully interchangeable. Tighter tolerance parts provide improved capacitance stability without requiring circuit redesign.

Q: Are all substitute parts available in the same packaging format? A: All listed substitute parts are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) surface mount format, matching the original component's mounting requirements. No package conversion or handling modifications are necessary.

Q: What compliance certifications apply to all substitute parts? A: All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). REACH status is unaffected for all parts. These certifications are consistent across KYOCERA AVX and KEMET manufacturers for the specified part numbers.
