0508YC104MAT2W Equivalent & Substitute Parts

Part Overview

The 0508YC104MAT2W is a 0.1 µF ±20% 16V ceramic capacitor in X7R dielectric with 0508 (1220 Metric) package configuration, manufactured by KYOCERA AVX. This component is classified as obsolete, though 738 pieces remain in stock as new original inventory. The part is designed for bypass and decoupling applications in surface mount configurations with low ESL (reverse geometry) construction.

Due to the obsolete product status, equivalent and substitute parts with active manufacturing status are necessary for ongoing design support, production continuity, and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the 0508YC104MAT2W is determined by the following critical parameters:

Mandatory Matching Parameters:

Capacitance: 0.1 µF (exact match required)
Temperature Coefficient: X7R (exact match required)
Package / Case: 0508 (1220 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

Tolerance: ±20% or ±10% (tighter tolerance acceptable)
Voltage Rating: 16V or higher (higher voltage acceptable for same capacitance and dielectric)
Thickness: 0.030" (0.76mm) or 0.040" (1.02mm) (higher voltage ratings require increased thickness)

Substitute parts are grouped into three categories: direct equivalents (matching all parameters including tolerance and voltage), upgraded voltage ratings (higher voltage with same or tighter tolerance), and cross-manufacturer alternatives (different manufacturer, identical electrical and mechanical specifications).

Engineering Selection Recommendations

Direct Equivalent (Active Status): The 0508YC104MAT9O is the direct functional equivalent with identical electrical and mechanical specifications. This part maintains the ±20% tolerance and 16V rating of the original 0508YC104MAT2W while offering active product status and immediate availability.

Tighter Tolerance Alternatives (Active Status): Parts 0508YC104KAT2A, 0508YC104KAT2S, 0508YC104KAT2U, and 0508YC104KAT2W provide ±10% tolerance with 16V rating in the same 0508 package. These are direct substitutes where improved capacitance tolerance is acceptable or beneficial. All are ROHS3 compliant with MSL 1 rating.

Upgraded Voltage Rating (Active Status): The 05083C104KAT2W (25V, ±10%) and 05083C104MAT2W (25V, ±20%) provide higher voltage margin while maintaining 0.1 µF capacitance and X7R temperature coefficient. These are suitable for applications where increased voltage headroom is required. The 05085C104KAT2W (50V, ±10%) and 05085C104MAT2W (50V, ±20%) offer maximum voltage rating within the same capacitance and package family.

High-Volume Alternative: The KGL21DR71E104KU offers the highest inventory availability (36,478 pieces) with 25V rating and ±10% tolerance, providing supply chain security for high-volume production requirements.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute? A: Yes. A capacitor rated for higher voltage (25V or 50V) is a valid substitute for the 16V rated 0508YC104MAT2W, provided all other parameters match: 0.1 µF capacitance, X7R temperature coefficient, 0508 package, and surface mount configuration. Higher voltage ratings provide additional design margin.

Q: What is the difference between ±20% and ±10% tolerance parts? A: Tolerance specifies the allowable deviation from the nominal 0.1 µF capacitance value. The ±20% tolerance (original part) allows capacitance between 0.08 µF and 0.12 µF. The ±10% tolerance allows 0.09 µF to 0.11 µF. Tighter tolerance (±10%) is a valid substitute where the original ±20% tolerance is acceptable.

Q: Does package thickness affect substitutability? A: Package thickness varies with voltage rating. The 16V rated parts have 0.030" (0.76mm) thickness, while 25V and 50V rated parts have 0.040" (1.02mm) thickness. Verify PCB assembly equipment and design clearances accommodate the thicker profile before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory requirements of the original 0508YC104MAT2W.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Can I mix different substitute parts in the same design? A: Yes, provided the circuit design accommodates the parameter variations. Mixing parts with different tolerances (±20% vs ±10%) or voltage ratings (16V, 25V, 50V) is acceptable if the application circuit tolerates these variations.
