08055A8R2CAT2M Equivalent & Substitute Parts

Part Overview

The 08055A8R2CAT2M is an 8.2 pF ceramic capacitor manufactured by KYOCERA AVX with a rated voltage of 50V, C0G/NP0 temperature coefficient, and 0805 (2012 Metric) surface mount package. This component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, manufacturing discontinuation, or design flexibility needs.

Substitute Part Grouping Explanation

Substitute parts for the 08055A8R2CAT2M are classified into two categories based on electrical parameter alignment:

Parametric Equivalent Parts maintain identical electrical specifications: 8.2 pF capacitance, ±0.25pF tolerance, 50V rated voltage, C0G/NP0 temperature coefficient, and -55°C to 125°C operating temperature range. These parts differ only in manufacturer or internal construction while meeting all functional requirements.

Upgrade Parts provide higher voltage ratings (100V) while maintaining all other electrical parameters. These parts are suitable for applications where increased voltage margin is acceptable or beneficial.

Direct Equivalent Parts from alternative manufacturers (KEMET, YAGEO, Viking Tech, Vishay Vitramon) meet all electrical and mechanical specifications of the original part, with variations only in physical dimensions (thickness) and internal construction characteristics.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the original 08055A8R2CAT2M component.

Direct Equivalent Selection: Parts C0805C829C5GAC7800 (KEMET), CC0805CRNPO9BN8R2 (YAGEO), MC05CTN5008R2 (Viking Tech), and VJ0805A8R2CXACW1BC (Vishay Vitramon) provide identical electrical specifications at 50V rated voltage with ±0.25pF tolerance. These are suitable for one-to-one replacement in existing designs.

Parametric Equivalent Selection: KGM21BCG1H8R2CT (KYOCERA AVX) from the same manufacturer series provides identical electrical performance and is recommended when maintaining manufacturer consistency is a design requirement.

Upgrade Selection: KGM21BCG2A8R2CT (KYOCERA AVX), C0805C829C1GAC7800 (KEMET), and CC0805CRNPO0BN8R2 (YAGEO) provide 100V rated voltage while maintaining all other electrical parameters. These parts are suitable for applications where increased voltage derating margin is required or preferred.

Tolerance Upgrade: CC0805BRNPO9BN8R2 (YAGEO) offers tighter tolerance of ±0.1pF compared to the standard ±0.25pF, providing enhanced capacitance stability for precision applications while maintaining 50V rating.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated substitute in place of the 50V original part? A: Yes. The 100V rated parts (KGM21BCG2A8R2CT, C0805C829C1GAC7800, CC0805CRNPO0BN8R2) are electrically compatible and provide additional voltage margin. All other parameters including capacitance, tolerance, temperature coefficient, and package remain identical.

Q: Are there physical dimension differences between substitute parts? A: Yes. While all parts use the 0805 (2012 Metric) package, thickness varies: original part is 0.037" (0.94mm), KEMET parts are 0.035" (0.88mm), and YAGEO/Vishay parts are 0.028" (0.70mm). Verify PCB layout clearance if height-constrained applications are involved.

Q: What is the difference between C0G and NP0 temperature coefficients? A: C0G and NP0 designations are equivalent specifications from different standards organizations. Both indicate zero temperature coefficient performance across the -55°C to 125°C operating range. All substitute parts meet this specification.

Q: Can I substitute parts from different manufacturers? A: Yes. All listed substitute parts from KEMET, YAGEO, Viking Tech, and Vishay Vitramon meet the electrical and mechanical specifications of the original KYOCERA AVX part. Verify compatibility with your procurement and supply chain requirements.

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.
