Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory matching parameters:

Capacitance: 820 pF (exact match required)
Package / Case: 0805 (2012 Metric) (exact match required)
Operating Temperature: -55°C ~ 125°C (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable variation parameters:

Voltage - Rated: May be equal to or greater than 25V
Tolerance: May be tighter (lower) than ±20%
Temperature Coefficient: May differ (X7R or C0G/NP0 acceptable)

Substitute parts are grouped by voltage rating and temperature coefficient to facilitate selection based on circuit requirements and performance characteristics.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the primary part 08053C821MAT2A.

Voltage rating selection: The original part is rated 25V. Substitute parts with higher voltage ratings (50V, 100V, 200V) are electrically compatible and provide increased voltage margin. Selection should be based on circuit voltage requirements and available board space, as higher voltage ratings may result in larger physical dimensions.

Temperature coefficient selection: The original part uses X7R coefficient. Substitute parts using C0G/NP0 coefficient offer superior temperature stability and lower capacitance drift across the operating temperature range. X7R coefficient substitutes (C0805C821J5RAC7800) maintain the original temperature characteristic.

Tolerance selection: The original part specifies ±20% tolerance. Substitute parts with tighter tolerances (±1%, ±2%, ±5%, ±10%) provide improved capacitance accuracy for precision circuit applications.

Manufacturer selection: KYOCERA AVX and KEMET are both established manufacturers with equivalent product quality and compliance certifications for this capacitor category.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 25V specification?

A: Yes. Higher voltage-rated capacitors (50V, 100V, 200V) are electrically compatible with circuits designed for 25V operation. The capacitor will operate safely at voltages below its rated maximum.

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

A: X7R coefficient exhibits capacitance variation of ±15% across the -55°C to 125°C operating range. C0G/NP0 coefficient provides superior stability with minimal capacitance drift across temperature. Selection depends on circuit sensitivity to capacitance variation.

Q: Are all substitute parts available in the same 0805 package?

A: Yes. All listed substitute parts use the 0805 (2012 Metric) surface mount package, ensuring mechanical and electrical compatibility with the original part footprint.

Q: Do substitute parts meet the same RoHS and moisture sensitivity requirements?

A: Yes. All substitute parts are ROHS3 compliant and rated MSL 1 (Unlimited), matching the original part specifications.

Q: Which substitute part offers the best tolerance accuracy?

A: KGM21BCG1H821FT and C0805C821F5GAC7800 both offer ±1% tolerance, providing the tightest capacitance accuracy among available substitutes.
