Substitute Part Grouping Explanation

Substitute parts for the 08056C102JAT2A are grouped based on the following substitution criteria:

Primary Matching Parameters:

Capacitance: 1000 pF (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

Allowed Variations:

Voltage Rating: May be equal to or greater than 6.3V
Temperature Coefficient: X7R or C0G/NP0 acceptable
Tolerance: ±1%, ±2%, or ±5% acceptable
Manufacturer: KYOCERA AVX or equivalent qualified manufacturers

Substitutes are divided into two categories: upgraded voltage ratings with improved temperature stability (C0G/NP0 dielectric), and equivalent voltage ratings with alternative temperature coefficients (X7R dielectric from different manufacturers).

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Characteristics): KGM21NR71C102JT provides equivalent X7R temperature coefficient with ±5% tolerance at 16V rating. This part maintains identical dielectric behavior to the original while offering higher voltage margin and greater inventory availability (23937 Pcs).

For Upgraded Performance (Improved Stability): KGM21BCG1H102FT offers C0G/NP0 temperature coefficient with ±1% tolerance at 50V rating. C0G/NP0 dielectric provides superior temperature stability and lower capacitance drift compared to X7R, suitable for precision applications. This part is ROHS3 compliant with highest inventory level (155542 Pcs).

For Maximum Voltage Margin: KGM21NR72D102JT provides 200V rating with X7R temperature coefficient and ±5% tolerance, offering maximum overvoltage protection while maintaining original dielectric characteristics. ROHS3 compliant with 10001 Pcs inventory.

For Alternative Manufacturer: 0805D102J500KHT from Knowles Novacap provides C0G/NP0 dielectric at 50V with ±5% tolerance. Operating temperature range extends to 200°C. REACH Affected status requires compliance verification in regulated applications.

All substitute parts are Active status, ROHS3 compliant (except Knowles Novacap which is REACH Affected), MSL 1 rated, and maintain identical 0805 package dimensions and surface mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use KGM21BCG1H102FT as a direct replacement for 08056C102JAT2A? A: Yes. Both parts share 1000 pF capacitance, 0805 package, and surface mount configuration. KGM21BCG1H102FT provides higher voltage rating (50V vs 6.3V) and superior temperature stability (C0G/NP0 vs X7R). The higher voltage rating provides additional safety margin in the circuit.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R dielectric exhibits ±15% capacitance change across -55°C to 125°C operating range. C0G/NP0 dielectric exhibits ±30 ppm/°C change, providing significantly better temperature stability. C0G/NP0 is preferred for precision timing and filtering applications.

Q: Are all substitute parts ROHS3 compliant? A: KYOCERA AVX parts (KGM series and 08056C102JAT2A) are ROHS3 compliant. The Knowles Novacap part (0805D102J500KHT) is REACH Affected and requires compliance verification for regulated markets.

Q: Can I substitute a 50V rated part for the original 6.3V part? A: Yes. Higher voltage ratings are acceptable substitutes provided all other parameters (capacitance, package, temperature range) match. The circuit will function identically; the higher voltage rating simply provides additional safety margin.

Q: What does MSL 1 (Unlimited) mean? A: MSL 1 indicates Moisture Sensitivity Level 1, meaning the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry MSL 1 rating.

Q: Are the physical dimensions identical across all substitute parts? A: All parts use 0805 (2012 Metric) package with 0.079" L x 0.049" W footprint. Thickness varies slightly: KYOCERA AVX X7R parts are 0.039" (1.00mm) maximum, KYOCERA AVX C0G parts are 0.037" (0.94mm) maximum, and Knowles Novacap part is 0.054" (1.37mm) maximum. Verify PCB clearance for the Knowles Novacap part in space-constrained designs.
