Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055C301JAT2A is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 300 pF (exact match required)
• Package size: 0805 (2012 Metric) (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Temperature coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)
• Tolerance: ±5% or tighter (±1%, ±2% acceptable as upgrades)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• MSL 1 (Unlimited) (mandatory)
• Active product status (preferred)

Substitute parts are grouped by voltage rating and temperature coefficient characteristics. Parts with higher voltage ratings (100V, 630V) provide enhanced performance margins. Parts with C0G/NP0 temperature coefficient offer superior stability compared to X7R, with tighter tolerance grades available.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance with MSL 1 rating, ensuring long-term availability and environmental regulatory adherence.

Direct Equivalents (Same Voltage, Same Tolerance): 08055A301JAT2A (KYOCERA AVX) and CC0805JRNPO9BN301 (YAGEO) provide direct functional equivalence with identical 50V rating and ±5% tolerance. These parts differ only in temperature coefficient (C0G/NP0 vs. X7R), offering improved temperature stability characteristics.

Upgraded Tolerance Grade: 08055A301FAT2A (KYOCERA AVX) and C0805C301J5GAC7800 (KEMET) maintain 50V rating while providing tighter ±1% tolerance specification, suitable for applications requiring enhanced capacitance accuracy.

Enhanced Voltage Margin: 08051A301FAT2A (KYOCERA AVX) and C0805C301J1GAC7800 (KEMET) provide 100V rated voltage with ±1% tolerance, delivering increased voltage safety margin for circuits operating below 50V.

High Voltage Application: C0805C301GBGAC7800 (KEMET) offers 630V rating with ±2% tolerance, applicable to high-voltage circuit designs requiring significant voltage headroom.

Frequently Asked Questions (FAQ)

Q: Can I substitute 08055C301JAT2A with a part having different temperature coefficient?

A: Yes. The main part uses X7R temperature coefficient. Substitute parts with C0G/NP0 temperature coefficient are acceptable and provide superior temperature stability. Both coefficients support the -55°C ~ 125°C operating range specified.

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

A: X7R exhibits ±15% capacitance variation across the operating temperature range. C0G/NP0 provides superior stability with minimal capacitance drift across temperature. For general purpose applications, both are functionally compatible.

Q: Can I use a 100V rated capacitor in place of the 50V rated part?

A: Yes. Higher voltage ratings provide increased safety margin and are electrically compatible in circuits designed for 50V operation. Physical dimensions remain identical in the 0805 package.

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

A: Yes. All listed substitute parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.01mm x 1.25mm), ensuring direct PCB compatibility.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life without moisture bake-out requirements. No special moisture control procedures are necessary during storage or handling.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting environmental and regulatory requirements for lead-free manufacturing and restricted substance limitations.

Q: Can tolerance grade affect circuit performance?

A: Tolerance grade determines capacitance accuracy. ±5% tolerance allows ±15 pF variation from 300 pF nominal. ±1% tolerance allows ±3 pF variation. Tighter tolerance grades benefit precision filtering and timing applications.
