05085C103MAT2W Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 05085C103MAT2W is a 10000 pF ceramic capacitor manufactured by KYOCERA AVX, designed for bypass and decoupling applications in surface mount configurations. This part features X7R temperature coefficient characteristics, 50V rated voltage, and low ESL (reverse geometry) construction in the 0508 (1220 Metric) package. The part is currently active in production with 753 units in stock. Substitute parts are necessary when primary inventory is depleted, when tighter tolerance specifications are required, or when alternative manufacturer sourcing is needed for supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 05085C103MAT2W is determined by the following critical parameters: capacitance value (10000 pF), rated voltage (50V), temperature coefficient (X7R), package type (0508/1220 Metric), and mounting configuration (Surface Mount MLCC). All substitute parts must maintain identical capacitance and voltage ratings. Tolerance variations (±20% to ±10%) are permitted when design specifications allow tighter tolerance requirements. Physical dimensions must remain compatible with the 0508 package footprint. All substitutes must maintain ROHS3 compliance and MSL 1 rating for manufacturing compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 05085C103KAT2A represents an upgrade option when tighter capacitance tolerance (±10%) is required for precision applications, while maintaining all other electrical and mechanical specifications identical to the main part. This substitute is preferred for designs where tolerance stack-up analysis demands improved accuracy.

The 05085C103MAT2A is a parametric equivalent from the same manufacturer with identical specifications to the main part, offering direct interchangeability with higher available inventory (4606 units).

The LLL215R71H103MA11L from Murata Electronics is a direct functional substitute meeting all electrical requirements. However, this part carries a Last Time Buy status, indicating discontinued production. Selection of this substitute should be limited to applications where existing design validation with Murata components exists or where supply chain diversification justifies qualification efforts. Physical dimensions show minor variations (length 0.049" vs 0.050", thickness 0.020" vs 0.040"), which remain within 0508 package compatibility but require PCB layout verification.

All substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring manufacturing process compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can 05085C103KAT2A replace 05085C103MAT2W directly?

A: Yes. The 05085C103KAT2A is a direct substitute with tighter tolerance (±10% vs ±20%). All electrical parameters, package dimensions, and compliance certifications are identical. This part is preferred when design specifications require improved capacitance accuracy.

Q: What is the difference between the KYOCERA AVX substitutes and the Murata part?

A: The KYOCERA AVX parts (05085C103MAT2A and 05085C103KAT2A) are actively produced and fully compatible. The Murata LLL215R71H103MA11L meets all electrical specifications but is in Last Time Buy status. Physical dimensions show minor variations in thickness (0.020" vs 0.040"), requiring PCB layout confirmation before use.

Q: Are all substitutes compatible with the same PCB footprint?

A: The KYOCERA AVX substitutes use identical 0508 package dimensions and are fully footprint compatible. The Murata part uses the same 0508 package but with reduced thickness (0.020" vs 0.040"), which may affect solder joint geometry and requires design review.

Q: Can I use these substitutes interchangeably in production?

A: The KYOCERA AVX parts (05085C103MAT2W, 05085C103MAT2A, and 05085C103KAT2A) are fully interchangeable. The Murata part requires design validation due to Last Time Buy status and physical dimension variations.

Q: What compliance certifications apply to all substitutes?

A: All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All meet ECCN EAR99 and HTSUS 8532.24.0020 classifications.
