08055AR82CAT2A Equivalent & Substitute Parts

Part Overview

The 08055AR82CAT2A is a 0.82 pF ceramic capacitor manufactured by KYOCERA AVX, designed for general-purpose applications requiring stable capacitance across temperature ranges. This surface-mount multilayer ceramic capacitor (MLCC) operates at 50V with C0G/NP0 temperature coefficient characteristics, ensuring minimal capacitance drift from -55°C to 125°C. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies. Equivalent substitutes are identified when manufacturers discontinue production lines, supply constraints occur, or design flexibility is required while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 08055AR82CAT2A is determined by strict equivalence across the following parameters:

• Capacitance value: 0.82 pF (exact match required)
• Capacitance tolerance: ±0.25pF (exact match required)
• Voltage rating: 50V (minimum; higher ratings acceptable)
• Temperature coefficient: C0G/NP0 (required for stability)
• Operating temperature range: -55°C ~ 125°C (minimum coverage required)
• Package: 0805 (2012 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Moisture sensitivity: MSL 1 or better (exact match required)
• Compliance: ROHS3 and REACH Unaffected status (required for regulated applications)

The CC0805CRNPO9BNR82 from YAGEO meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CC0805CRNPO9BNR82 (YAGEO) is a direct functional equivalent to the 08055AR82CAT2A (KYOCERA AVX). Both parts are active products with identical electrical specifications, package geometry, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the CC0805CRNPO9BNR82 be used as a direct replacement for the 08055AR82CAT2A?

A: Yes. Both parts share identical capacitance (0.82 pF), tolerance (±0.25pF), voltage rating (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package (0805), and compliance certifications. No circuit redesign or board layout modification is required.

Q: Are there physical dimension differences between these parts?

A: Both parts use the 0805 (2012 Metric) package. The main part specifies maximum thickness of 0.037" (0.94mm), while the substitute specifies 0.028" (0.70mm). The substitute's reduced thickness is compatible with standard 0805 footprints and does not affect assembly or performance.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G/NP0 designation indicates minimal capacitance variation across the operating temperature range (-55°C ~ 125°C). This stability is critical for precision circuits where capacitance drift must be controlled. Both parts meet this requirement identically.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and ROHS3 compliance, indicating suitability for standard commercial and industrial applications. Specific reliability requirements should be evaluated against application-level standards and qualification protocols.

Q: Can a higher voltage-rated capacitor substitute for the 50V rating?

A: Substitution with higher voltage ratings is electrically acceptable, as voltage derating improves reliability margins. However, only parts meeting all other specified parameters (capacitance, tolerance, temperature coefficient, package, and compliance) qualify as direct equivalents.
