Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055E473MAT4A is determined by strict electrical and mechanical parameter alignment:

Mandatory Matching Parameters:

• Capacitance: 0.047 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 50V minimum (equal or higher acceptable)
• Temperature Coefficient: Z5U (exact match required)
• Operating Temperature Range: 10°C ~ 85°C (must support this range)
• Package: 0805 (2012 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

The KEMET C0805C473M5UAC7800 meets all mandatory parameters and is functionally interchangeable with the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the 08055E473MAT4A and C0805C473M5UAC7800 are Active product status components with ROHS3 compliance and REACH Unaffected certification. Selection between these parts may be based on inventory availability, supplier preference, or lead time requirements. The KEMET C0805C473M5UAC7800 features a reduced maximum thickness (0.88mm versus 1.30mm), which may provide design advantages in space-constrained applications. Both parts are functionally equivalent and suitable for general-purpose ceramic capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can the C0805C473M5UAC7800 directly replace the 08055E473MAT4A? A: Yes. Both components share identical electrical specifications (0.047 µF ±20% 50V Z5U), identical package designation (0805 / 2012 Metric), and identical operating temperature range (10°C ~ 85°C). No circuit redesign or board layout modification is required for direct substitution.

Q: Are there any physical dimension differences between these parts? A: The length and width dimensions are functionally equivalent (0.079" x 0.049"). The KEMET C0805C473M5UAC7800 has a reduced maximum thickness of 0.88mm compared to 1.30mm for the KYOCERA AVX part. This difference is within the tolerance stack for 0805 package design and does not affect PCB assembly, solder joint reliability, or electrical performance.

Q: Do both parts have the same moisture sensitivity requirements? A: Yes. Both components are classified as MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: Are there compliance differences between the substitutes? A: No. Both parts carry ROHS3 compliance and REACH Unaffected status. No additional documentation or certification is required for regulatory compliance when substituting between these parts.

Q: Which part should be selected for a new design? A: Selection is based on procurement factors including supplier availability, pricing, and lead time. From an engineering standpoint, both parts are functionally and mechanically equivalent for this application.
