Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Core Compatibility Requirements:

• Capacitance value: 300 pF (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• 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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variations:

• Tolerance: ±1% to ±5% (tighter tolerance acceptable)
• Voltage Rating: 100V or higher (higher voltage acceptable)
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)
• Manufacturer: Different manufacturers permitted if all core parameters match

The three substitute parts listed below meet all core compatibility requirements while offering variations in tolerance, voltage rating, and temperature coefficient characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active status and ROHS3 compliant, meeting regulatory requirements equivalent to the main part.

08051A301FAT2A (KYOCERA AVX): Direct manufacturer equivalent with improved tolerance specification (±1% versus ±5%). Identical voltage rating and package dimensions. Temperature coefficient differs (C0G/NP0 versus X7R), providing superior temperature stability characteristics. Suitable for applications requiring tighter capacitance tolerance.

C0805C301GBGAC7800 (KEMET): Offers elevated voltage rating (630V versus 100V) with improved tolerance (±2%). Temperature coefficient is C0G/NP0. Maximum thickness specification is 0.039" (1.00mm), slightly higher than the main part. Suitable for high-voltage circuit applications or designs requiring voltage margin.

C0805C301J1GAC7800 (KEMET): Maintains 100V voltage rating and ±5% tolerance matching the main part specifications. Temperature coefficient is C0G/NP0. Thickness specification is 0.035" (0.88mm), lower than the main part. Suitable for space-constrained applications or as a direct functional equivalent with alternative manufacturer sourcing.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating? A: Yes. C0805C301GBGAC7800 rated at 630V is electrically compatible with circuits designed for 100V operation. Higher voltage rating provides additional safety margin and does not negatively affect circuit performance.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance variation across temperature. Both are acceptable for general purpose applications; C0G/NP0 is preferred for precision circuits.

Q: Are there physical compatibility concerns with thickness variations? A: Thickness variations (0.035" to 0.039") are within standard 0805 package specifications. All parts are mechanically compatible with standard PCB assembly processes and component placement equipment.

Q: Can I substitute based on tolerance alone? A: No. Tolerance is one parameter among many. All core parameters (capacitance, voltage, package, temperature range, compliance status) must match or exceed the original specification. Tolerance improvements (±1% or ±2% versus ±5%) are acceptable enhancements.

Q: Which substitute offers the best overall compatibility? A: C0805C301J1GAC7800 provides the closest functional match to 08051C301JAT2A, maintaining identical voltage rating and tolerance while offering alternative manufacturer sourcing and improved thickness specification.

Q: Are all substitutes available in the same packaging format? A: Yes. All parts are supplied in Tape & Reel (TR) packaging, standard for surface mount component distribution and automated assembly processes.
