Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Secondary Variation Parameters (Allowed to Differ):

Engineering Selection Recommendations

KYOCERA AVX KGM Series (Same Manufacturer Upgrades):

KGM21BCG1H471FT, KGM21BCG1H471GT, and KGM21BCG1H471KT offer C0G/NP0 temperature coefficient at 50V rating with improved tolerance specifications (±1%, ±2%, ±10% respectively). These are direct upgrades for applications requiring superior temperature stability and tighter capacitance tolerance while maintaining the same voltage rating.

KGM21BCG2A471FT, KGM21BCG2A471GT, and KGM21BCG2A471KT provide 100V rated variants with C0G/NP0 temperature coefficient. These are suitable for applications requiring higher voltage margin or operating in elevated voltage environments while maintaining the same 470 pF capacitance.

KGM21NR71H471JT and KGM21NR71H471MT maintain X7R temperature coefficient at 50V with ±5% and ±20% tolerance respectively. KGM21NR71H471MT is a direct functional equivalent with identical tolerance to the main part.

KGM21NR72D471JT extends voltage rating to 200V with X7R temperature coefficient and ±5% tolerance for high-voltage applications.

KEMET Direct Equivalent:

C0805C471M5RAC7800 provides direct substitution with matching 470 pF capacitance, ±20% tolerance, 50V rating, and X7R temperature coefficient. All parts maintain ROHS3 compliance, MSL 1 rating, and Active product status.

Frequently Asked Questions (FAQ)

Q: Can KGM21BCG1H471FT replace 08055C471MAT2E directly?

A: Yes. Both parts share identical capacitance (470 pF), voltage rating (50V), package (0805), and operating temperature range (-55°C ~ 125°C). KGM21BCG1H471FT offers superior tolerance (±1% vs ±20%) and C0G/NP0 temperature coefficient instead of X7R. This substitution is valid when tighter tolerance and improved temperature stability are acceptable or beneficial.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change over the operating temperature range. C0G/NP0 provides ±30 ppm/°C, resulting in significantly lower capacitance drift. C0G/NP0 is preferred for precision applications; X7R is suitable for general-purpose filtering and decoupling.

Q: Can I use KGM21BCG2A471FT (100V) instead of the 50V rated part?

A: Yes. Higher voltage rating provides additional safety margin and is electrically compatible. The 100V rated part will function correctly in circuits designed for 50V operation. This substitution is valid when component availability or supply chain considerations favor the higher voltage variant.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part (08055C471MAT2E) uses unspecified packaging. Most KGM substitutes use Tape & Reel (TR) packaging. KGM21BCG2A471FT uses Cut Tape (CT) & Digi-Reel®. KEMET C0805C471M5RAC7800 uses Tape & Reel (TR). Packaging affects handling and automated assembly compatibility but does not affect electrical performance.

Q: Is KEMET C0805C471M5RAC7800 a suitable alternative to KYOCERA AVX parts?

A: Yes. C0805C471M5RAC7800 matches the main part specification exactly: 470 pF, ±20%, 50V, X7R, 0805 package. Both manufacturers are ROHS3 compliant with MSL 1 rating. This substitution is valid for applications where multi-source qualification is required or KEMET inventory is preferred.

Q: What happens if I use a part with ±1% tolerance instead of ±20%?

A: The ±1% tolerance part will have tighter capacitance control, resulting in more predictable circuit behavior. This is a beneficial substitution for precision applications. No negative effects occur; the circuit will function with improved performance characteristics.
