Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 0.1 µF capacitance, ±20% tolerance, 50V voltage rating, X7R temperature coefficient, and 0805 package form factor. These parts are sourced from alternative manufacturers (KYOCERA AVX KGM series, Walsin Technology, KEMET, YAGEO) and support equivalent circuit performance with interchangeable mechanical fit.

Upgrade Substitutes offer improved tolerance grades (±5% or ±10%) or higher voltage ratings (100V) while maintaining the same capacitance value, temperature coefficient, and package dimensions. These parts provide enhanced performance margins for applications requiring tighter tolerance control or higher voltage headroom.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and -55°C ~ 125°C operating temperature range as specified for the main part.

Engineering Selection Recommendations

Direct Substitutes (Same Specifications): KGM21NR71H104MM, 0805B104M500CT, C0805C104M5RAC7800, and CC0805MRX7R9BB104 provide equivalent electrical and mechanical performance. All maintain Active product status and ROHS3 compliance. Selection among these options is based on supply availability, packaging format (Tape & Reel vs. Cut Tape), and procurement lead times.

Tolerance-Improved Substitutes: KGM21NR71H104JM, KGM21NR71H104JT (±5% tolerance) and KGM21NR71H104KM, KGM21NR71H104KT (±10% tolerance) are suitable for applications requiring tighter capacitance control while maintaining 50V rating and X7R characteristics. These parts support designs with stricter tolerance requirements without circuit redesign.

Voltage-Upgraded Substitute: KGM21AR72A104MU provides 100V rating with identical 0.1 µF capacitance and ±20% tolerance. This part is applicable for designs requiring higher voltage margin or operating in elevated voltage environments. Note the increased thickness (0.057" vs. 0.037") due to higher voltage construction.

All substitute parts are RoHS3 compliant with MSL 1 rating and support the full -55°C ~ 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can KGM21NR71H104MM replace 08055C104MAT4P directly? A: Yes. Both parts share identical electrical specifications (0.1 µF, ±20%, 50V, X7R) and 0805 package form factor. The primary difference is manufacturer and packaging format. Mechanical fit and circuit performance are equivalent.

Q: What is the difference between ±20%, ±10%, and ±5% tolerance grades? A: Tolerance defines the allowable capacitance deviation from the nominal 0.1 µF value. ±20% allows 0.08–0.12 µF, ±10% allows 0.09–0.11 µF, and ±5% allows 0.095–0.105 µF. Tighter tolerances (±5%, ±10%) are required for precision filtering, timing circuits, or applications with strict capacitance requirements.

Q: Can I use KGM21AR72A104MU (100V) in place of the 50V rated part? A: Yes, from an electrical standpoint. The 100V part provides higher voltage margin and is backward compatible in 50V circuits. However, the increased thickness (0.057" vs. 0.037") may affect PCB layout and assembly clearances. Verify mechanical fit before substitution.

Q: What does X7R temperature coefficient mean? A: X7R specifies the capacitance change over temperature. X7R ceramic capacitors maintain capacitance within ±15% across the -55°C ~ 125°C operating range. All listed substitutes maintain this specification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging is supplied on continuous carrier tape for automated assembly equipment. Cut Tape (CT) is supplied in shorter tape segments for manual or lower-volume assembly. Both formats contain identical components; packaging selection depends on assembly process requirements.
