0508YC103MAT2W Equivalent & Substitute Parts

Part Overview

The 0508YC103MAT2W is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 16V with X7R temperature coefficient and ±20% tolerance. This surface mount multilayer ceramic capacitor (MLCC) is designed for bypass and decoupling applications in electronic circuits. The part features low ESL (reverse geometry) construction and is packaged in 0508 (1220 Metric) form factor.

Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions.

For Active Production Designs: Select from KYOCERA AVX parts with Active product status: 05083C103KAT2A, 05085C103KAT2A, 05085C103MAT2A, or KGL21PR71E103KT. These parts provide long-term availability and supply chain stability.

For Voltage Margin Enhancement: Parts rated at 50V (05085C103KAT2A or 05085C103MAT2A) provide increased voltage headroom over the original 16V specification while maintaining identical capacitance and package dimensions.

For Tolerance Improvement: Parts with ±10% tolerance (05083C103KAT2A, 05085C103KAT2A, or KGL21PR71E103KT) offer tighter capacitance control compared to the original ±20% specification.

For Space-Constrained Applications: KGL21PR71E103KT and LLL215R71H103MA11L feature reduced thickness (0.022" and 0.020" respectively) while maintaining all other electrical and mechanical specifications.

For End-of-Life Mitigation: LLL215R71H103MA11L (Murata Electronics) is designated Last Time Buy status. Use only if supply of KYOCERA AVX alternatives is unavailable and design validation has been completed.

Frequently Asked Questions (FAQ)

Q: Can I use a 25V-rated part in place of the 16V original? A: Yes. The 05083C103KAT2A and KGL21PR71E103KT are both rated 25V and meet all other electrical and mechanical specifications. Higher voltage ratings provide additional safety margin without affecting circuit performance in bypass and decoupling applications.

Q: What is the difference between ±10% and ±20% tolerance parts? A: Tolerance specifies the allowable deviation from the nominal 10000 pF capacitance value. ±10% tolerance parts (05083C103KAT2A, 05085C103KAT2A, KGL21PR71E103KT) maintain capacitance between 9000-11000 pF, while ±20% parts (0508YC103MAT2W, 05085C103MAT2A, LLL215R71H103MA11L) range from 8000-12000 pF. Select ±10% parts for applications requiring tighter capacitance control.

Q: Are there physical size differences between substitute parts? A: All parts share the same 0508 (1220 Metric) package footprint (0.050" L x 0.079" W). Thickness varies: standard parts measure 0.040" (1.02mm), while KGL21PR71E103KT measures 0.022" (0.56mm) and LLL215R71H103MA11L measures 0.020" (0.50mm). Thinner variants fit applications with height constraints.

Q: Can I substitute the Murata part (LLL215R71H103MA11L) for KYOCERA AVX parts? A: Yes, electrically and mechanically compatible. However, LLL215R71H103MA11L carries Last Time Buy status, indicating discontinued production. Use only when KYOCERA AVX alternatives are unavailable and design validation is complete.

Q: Do all substitute parts maintain the same operating temperature range? A: Yes. All listed parts operate across -55°C ~ 125°C with X7R temperature coefficient, ensuring consistent performance across the full temperature spectrum.

Q: Which part should I select for new designs? A: For new designs, select from active KYOCERA AVX parts: 05083C103KAT2A (25V, ±10%), 05085C103KAT2A (50V, ±10%), or 05085C103MAT2A (50V, ±20%). These provide long-term supply availability and support.
