Engineering Selection Recommendations

All substitute parts listed are Active status products from KYOCERA AVX and maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) ratings consistent with the original 08055C103MAT6N specification.

Same Voltage Tier (50V): KGM21NR71H103KT provides a direct voltage-rated substitute with improved tolerance (±10% versus ±20%). This part is suitable for applications where tighter capacitance tolerance is beneficial without requiring elevated voltage margin.

Higher Voltage Tiers (100V, 200V, 250V): Substitutes rated at 100V, 200V, and 250V are electrically compatible and provide increased design margin for voltage stress. These parts accommodate applications where circuit voltage may approach or exceed the original 50V specification. Selection among these tiers depends on available board space, as higher voltage ratings result in increased component thickness.

Tolerance Selection: Parts with ±5% tolerance (KGM21NR72A103JT, KGM21AR72D103JU) are available at 100V and 200V ratings for applications requiring tighter capacitance control. Parts with ±10% tolerance are available across all voltage tiers. Parts with ±20% tolerance match the original specification and are available at 50V, 100V, and 200V ratings.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part rated at a higher voltage than the original 50V specification?

A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. The voltage rating indicates the maximum voltage the capacitor can safely withstand. Using a higher-rated part provides design margin and does not degrade circuit performance. However, verify that increased component thickness does not create PCB assembly conflicts.

Q: What is the difference between ±5%, ±10%, and ±20% tolerance ratings?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 10000 pF value. ±20% allows capacitance between 8000 pF and 12000 pF. ±10% allows 9000 pF to 11000 pF. ±5% allows 9500 pF to 10500 pF. Tighter tolerances are required for applications where precise capacitance values are critical to circuit function.

Q: Are Tray and Tape & Reel packaging formats interchangeable?

A: Both formats contain identical components and are electrically equivalent. The difference is in distribution and handling. Tray packaging is suitable for manual assembly or small-volume production. Tape & Reel format is optimized for automated pick-and-place assembly equipment. Select based on your assembly process requirements.

Q: Does increased component thickness affect PCB design?

A: Component thickness varies among substitutes due to voltage rating differences. The original 08055C103MAT6N has maximum thickness of 0.037" (0.94mm). Substitutes at 100V rating have 0.039" (1.00mm) thickness. Substitutes at 200V rating have 0.057" (1.45mm) thickness. Verify that your PCB layout and assembly process accommodate the selected part's thickness to avoid clearance issues with adjacent components or solder reflow profiles.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring compatibility with modern manufacturing and environmental standards.
