Engineering Selection Recommendations

The MA0805XR103J500 manufactured by Meritek qualifies as a direct substitute for the 08055C103JAT4H based on complete electrical parameter equivalence and compliance alignment. Both components share identical capacitance, tolerance, voltage rating, and temperature coefficient specifications. Both maintain RoHS3 compliance and MSL 1 classification, ensuring regulatory and environmental compatibility.

Physical dimension variance (2.01mm vs 2.10mm length) remains within standard 0805 package tolerances and does not affect PCB footprint compatibility or assembly processes. Both components are classified as Active product status with unlimited moisture sensitivity level, indicating equivalent handling and storage requirements.

Selection between these components should be based on availability, lead time, and procurement cost, as all technical and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the MA0805XR103J500 be used as a direct replacement for the 08055C103JAT4H in existing designs?

A: Yes. Both components meet identical electrical specifications (10000 pF, ±5%, 50V, X7R) and share the same 0805 package classification. Physical dimensions fall within standard package tolerances. No circuit redesign or PCB layout modification is required.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8532.24.0020) codes. Moisture sensitivity level and operating temperature ranges are identical.

Q: What is the significance of the X7R temperature coefficient?

A: X7R designation indicates the capacitor maintains stable capacitance across the -55°C to 125°C operating temperature range with minimal drift. Both substitute parts share this specification, ensuring equivalent thermal performance in circuit applications.

Q: Does the slight dimensional difference (2.01mm vs 2.10mm) affect PCB assembly?

A: No. Both components conform to the 0805 (2012 Metric) package standard. The 0.09mm length variation is within standard manufacturing tolerances and does not impact solder pad spacing, pick-and-place equipment compatibility, or reflow soldering processes.

Q: What is MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 classification indicates the component has unlimited shelf life under normal storage conditions without requiring desiccant packaging or baking procedures prior to assembly. Both parts share this classification.

Q: Can these capacitors be used interchangeably in high-frequency applications?

A: Both components are rated for general-purpose applications with identical electrical parameters. Application suitability depends on circuit-specific frequency requirements, which are not specified in the component data provided.
