Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical electrical specifications (0.027 µF, ±10%, 50V, X7R) and package dimensions. These parts are interchangeable without circuit modification:

C0805C273K5RAC7800 (KEMET)
CC0805KRX7R9BB273 (YAGEO)
CL21B273KBANNNC (Samsung Electro-Mechanics)
VJ0805Y273KXACW1BC (Vishay Vitramon)

Upgrade Substitutes provide enhanced electrical performance while maintaining the same capacitance, package, and temperature coefficient. These include:

Improved tolerance (±5% vs ±10%): KGM21NR71H273JT, C0805C273J5RAC7800
Higher voltage rating (100V vs 50V): KGM21AR72A273JU, KGM21AR72A273KU, C0805C273K1RAC7800

All substitute parts share the following critical parameters with the main part: 0.027 µF capacitance, X7R temperature coefficient, 0805 package, surface mount MLCC mounting type, and -55°C ~ 125°C operating temperature range.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications): Select from C0805C273K5RAC7800, CC0805KRX7R9BB273, CL21B273KBANNNC, or VJ0805Y273KXACW1BC. All are ROHS3 compliant and maintain 0.027 µF ±10% at 50V with X7R characteristics. These parts are functionally identical to the main part and require no circuit redesign.

For Improved Tolerance (±5%): KGM21NR71H273JT or C0805C273J5RAC7800 provide tighter capacitance tolerance while maintaining 50V rating and X7R performance. Both are ROHS3 compliant. Selection depends on preferred manufacturer and packaging requirements.

For Higher Voltage Margin (100V Rating): KGM21AR72A273JU, KGM21AR72A273KU, or C0805C273K1RAC7800 offer 100V rating with identical 0.027 µF capacitance and X7R coefficient. These are suitable for applications requiring increased voltage headroom. All are ROHS3 compliant. Note increased thickness may affect PCB layout in space-constrained designs.

Compliance Consideration: The main part 08055C273KA72A is RoHS non-compliant. All listed substitutes are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated capacitor in place of the 50V part? A: Yes. Higher voltage-rated capacitors (KGM21AR72A273JU, KGM21AR72A273KU, C0805C273K1RAC7800) are electrically compatible and provide additional safety margin. Verify PCB layout accommodates increased thickness (0.057" vs 0.037" for the main part).

Q: What is the difference between direct substitutes and upgrade substitutes? A: Direct substitutes maintain identical electrical specifications (0.027 µF ±10% at 50V). Upgrade substitutes offer improved tolerance (±5%) or higher voltage rating (100V) while preserving the same capacitance and temperature coefficient. Both categories are functionally compatible.

Q: Are all substitute parts RoHS compliant? A: All listed substitutes are ROHS3 compliant. The main part 08055C273KA72A is RoHS non-compliant. For new designs or production requiring RoHS compliance, select any substitute from the provided list.

Q: Does package thickness affect PCB assembly? A: Yes. Thickness varies from 0.030" (CL21B273KBANNNC) to 0.057" (100V KYOCERA AVX parts). Verify PCB clearance and reflow profile compatibility, particularly for 100V-rated parts with increased thickness. Standard 50V direct substitutes have thickness between 0.033" and 0.037".

Q: Can I mix manufacturers in the same circuit? A: Yes. All substitute parts share identical capacitance, voltage, temperature coefficient, and package specifications. Mixing manufacturers is acceptable from an electrical standpoint. Verify procurement and supply chain consistency for production designs.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component requires no special moisture control during storage or handling. All parts listed, including the main part, have MSL 1 rating.
