KYOCERA AVX 05083C102MAT2W Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 05083C102MAT2W is a 1000 pF ceramic capacitor rated at 25V with X7R temperature coefficient, designed for surface mount applications in the 0508 (1220 Metric) package. This component is classified as Active and is ROHS3 compliant. The part is commonly used in bypass and decoupling applications where stable capacitance across temperature ranges is required. Substitute parts are identified when design requirements allow for higher voltage ratings or improved tolerance specifications while maintaining identical physical dimensions and core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 05083C102MAT2W is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 1000 pF (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)
• Physical Dimensions: 0.050" L x 0.079" W, 0.040" max thickness (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 25V
• Tolerance: May be equal to or tighter than ±20%

The substitute part 05085C102KAT2A meets all mandatory matching criteria and provides an upgrade in voltage rating (50V vs. 25V) and tolerance specification (±10% vs. ±20%), making it suitable for applications where higher voltage margin or tighter capacitance tolerance is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 05083C102MAT2W and 05085C102KAT2A are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

The 05085C102KAT2A substitute part is electrically and mechanically compatible with the 05083C102MAT2W. The higher voltage rating (50V) provides additional safety margin in applications where the original 25V specification is met but design headroom is desired. The tighter tolerance (±10%) offers improved capacitance accuracy compared to the ±20% specification of the main part.

Selection between these parts depends on circuit requirements: use the 05083C102MAT2W where the 25V rating and ±20% tolerance are sufficient; use the 05085C102KAT2A where higher voltage margin or tighter tolerance specifications are required.

Frequently Asked Questions (FAQ)

Q: Can the 05085C102KAT2A be used as a direct replacement for the 05083C102MAT2W?

A: Yes. Both parts share identical capacitance (1000 pF), temperature coefficient (X7R), package dimensions (0508/1220 Metric), and operating temperature range (-55°C ~ 125°C). The substitute part has a higher voltage rating and tighter tolerance, which are compatible with applications designed for the original part.

Q: What is the difference between the two parts?

A: The primary differences are voltage rating (25V vs. 50V) and tolerance (±20% vs. ±10%). The 05085C102KAT2A provides higher voltage margin and improved capacitance accuracy. Physical dimensions and mounting characteristics are identical.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging and are Surface Mount, MLCC components in the 0508 (1220 Metric) package.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: Which part should I select for a new design?

A: Selection depends on circuit voltage requirements and tolerance specifications. If your design operates below 25V and ±20% tolerance is acceptable, either part is suitable. If higher voltage margin or tighter tolerance is beneficial, the 05085C102KAT2A is the appropriate choice.
