Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0508YC104MAT9O is determined by the following critical parameters:

Primary Compatibility Criteria:

• Capacitance value: 0.1 µF (exact match required)
• Temperature coefficient: X7R (maintains stable capacitance across operating temperature range)
• Package / Case: 0508 (1220 Metric) (ensures mechanical and electrical compatibility)
• Mounting type: Surface Mount, MLCC (maintains assembly process compatibility)
• Operating temperature range: -55°C to 125°C (functional equivalence)

Secondary Compatibility Parameters:

• Voltage rating: 16V minimum (substitutes may exceed this rating)
• Tolerance: ±20% or tighter (substitutes with ±10% tolerance are acceptable upgrades)
• RoHS and REACH compliance status (regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

Substitute parts are grouped into two categories: direct equivalents (matching all primary parameters) and upgraded alternatives (improved tolerance or voltage rating while maintaining primary compatibility).

Parameter Comparison

Engineering Selection Recommendations

0508YC104KAT2A (KYOCERA AVX - Upgrade) This substitute offers improved tolerance specification (±10% versus ±20%) while maintaining identical voltage rating, temperature coefficient, and package dimensions. Both parts are Active in product status with ROHS3 compliance. This part is suitable for applications requiring tighter capacitance tolerance. Inventory availability is significantly higher (4887 pcs), supporting supply chain continuity.

KGL21DR71E104MU (KYOCERA AVX - MFR Recommended) This manufacturer-recommended substitute increases voltage rating to 25V while maintaining 0.1 µF capacitance and X7R temperature coefficient. The higher voltage rating provides additional design margin for circuits operating near the 16V specification limit. Both parts are Active in product status with ROHS3 compliance. Thickness increases to 0.040" (1.02mm), requiring PCB layout verification. Inventory availability is highest among all substitutes (7697 pcs).

LLL216R71E104MA01L (Murata Electronics - Upgrade) This cross-manufacturer substitute provides 25V voltage rating with equivalent capacitance and temperature coefficient. Dimensions vary slightly (1.25mm length, 0.70mm thickness), requiring mechanical compatibility verification in space-constrained applications. Product status is Last Time Buy, indicating limited future availability. ROHS3 compliance and MSL 1 rating are maintained. Use this substitute only when supply of KYOCERA AVX alternatives is unavailable.

Frequently Asked Questions (FAQ)

Q: Can I use 0508YC104KAT2A as a direct replacement for 0508YC104MAT9O? A: Yes. Both parts share identical capacitance (0.1 µF), voltage rating (16V), temperature coefficient (X7R), and package dimensions (0508/1220 Metric). The 0508YC104KAT2A offers improved tolerance (±10% versus ±20%), making it a compatible upgrade with no circuit modifications required.

Q: What is the difference between the 16V and 25V rated substitutes? A: The main part and 0508YC104KAT2A are rated for 16V operation. KGL21DR71E104MU and LLL216R71E104MA01L are rated for 25V, providing higher voltage margin. The 25V parts are mechanically larger (increased thickness), requiring PCB layout verification. Use 25V substitutes only when circuit voltage specifications permit and space constraints allow.

Q: Are there any physical dimension differences I should consider? A: The KYOCERA AVX parts (0508YC104MAT9O, 0508YC104KAT2A, KGL21DR71E104MU) maintain consistent length and width within the 0508 package. KGL21DR71E104MU has increased thickness (0.040" versus 0.030"), which may affect PCB clearance. The Murata part (LLL216R71E104MA01L) has slightly reduced length (1.25mm versus 1.27mm) and thickness (0.028"), which may require footprint verification.

Q: Which substitute should I select for new designs? A: For new designs with active product status and maximum inventory availability, KGL21DR71E104MU is recommended. It provides 25V voltage rating for design margin while maintaining KYOCERA AVX manufacturing consistency and highest stock levels (7697 pcs). For applications with strict 16V specifications and tighter tolerance requirements, 0508YC104KAT2A is suitable.

Q: Is the Murata part (LLL216R71E104MA01L) a viable long-term option? A: The Murata part carries Last Time Buy status, indicating discontinued production with limited future availability. Use this substitute only when KYOCERA AVX alternatives are unavailable. For long-term supply chain planning, prioritize Active status parts (0508YC104KAT2A or KGL21DR71E104MU).

Q: Do all substitutes maintain RoHS and REACH compliance? A: Yes. All listed substitutes are ROHS3 Compliant and REACH Unaffected, maintaining regulatory equivalence with the main part. Moisture Sensitivity Level 1 (Unlimited) is consistent across all parts, requiring no changes to handling or storage procedures.
