Substitute Part Grouping Explanation
Substitution is determined by three critical parameters: capacitance value, temperature coefficient, and package form factor. All substitute parts maintain 10000 pF capacitance, X7R temperature coefficient, and 0805 package compatibility with the main part. Substitutes are grouped by voltage rating, which determines physical thickness and application suitability. Tolerance variations (±5%, ±10%, ±20%) are permitted within the same voltage class. All parts are KYOCERA AVX manufacture, Active status, and ROHS3 compliant.

Engineering Selection Recommendations
All substitute parts maintain Active product status and ROHS3 compliance. Selection between 50V, 100V, 200V, and 250V rated parts depends on circuit voltage requirements. Higher voltage ratings provide design margin but increase component thickness. The 50V class (08055C103MAT7A and KGM21NR71H103KT) offers minimum thickness at 0.037"-0.039". The 100V class maintains 0.039" thickness with improved voltage headroom. The 200V class increases thickness to 0.057" and the 250V class to 0.051". Tolerance selection (±5%, ±10%, ±20%) should align with circuit performance requirements. All parts are MSL 1 (Unlimited) and suitable for standard reflow assembly processes.
Frequently Asked Questions (FAQ)
Q: Can I substitute 08055C103MAT7A with a higher voltage rated part? A: Yes. Higher voltage rated parts (100V, 200V, 250V) are electrically compatible substitutes. Verify PCB layout accommodates increased component thickness before selection.
Q: What is the difference between ±5%, ±10%, and ±20% tolerance parts? A: Tolerance specifies the allowable capacitance deviation from nominal 10000 pF. ±5% tolerance provides tighter capacitance control (9500-10500 pF), ±10% allows 9000-11000 pF, and ±20% allows 8000-12000 pF. Select based on circuit filtering or timing requirements.
Q: Are all substitute parts pin-compatible? A: Yes. All parts use identical 0805 (2012 Metric) surface mount package with same footprint and pad layout.
Q: Does voltage rating affect reliability? A: Operating at lower voltage stress (using higher rated parts) does not degrade reliability. All parts maintain -55°C to 125°C operating range and MSL 1 moisture sensitivity.
Q: What is the impact of thickness variation on PCB assembly? A: Thickness ranges from 0.037" to 0.057". Verify reflow oven profile and component placement equipment accommodate maximum thickness. Consult assembly process documentation for clearance requirements.
Q: Are all parts ROHS3 compliant? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected.
