Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC330MAT1A is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance value: 33 pF (exact match required)
• Package format: 1808 (4520 Metric) surface-mount configuration
• Operating temperature range: -55°C ~ 125°C minimum
• Voltage rating: Equal to or greater than 1500V
• Mounting type: Surface Mount, MLCC
• RoHS3 compliance status
• Moisture sensitivity level: MSL 1 or better

Allowable Parameter Variations:

• Temperature coefficient: C0G/NP0 or X7R (both acceptable for general-purpose applications)
• Tolerance: ±10% or ±20% (tighter tolerance acceptable)
• Physical dimensions: Minor variations within 1808 package specification allowed

The substitute part C4520C0G3F330K160KA from TDK Corporation meets all mandatory criteria while offering enhanced voltage rating (3000V vs. 1500V) and improved tolerance specification (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1808SC330MAT1A and C4520C0G3F330K160KA are active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific voltage requirements and tolerance specifications.

The original 1808SC330MAT1A (KYOCERA AVX) is suitable for applications operating at or below 1500V with X7R temperature coefficient performance. The substitute C4520C0G3F330K160KA (TDK Corporation) provides enhanced voltage margin (3000V rating) and tighter capacitance tolerance (±10%), making it appropriate for designs requiring higher voltage headroom or improved capacitance stability. Both components share identical package geometry, operating temperature range, and moisture sensitivity classification, ensuring mechanical and thermal compatibility in surface-mount PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can C4520C0G3F330K160KA replace 1808SC330MAT1A in all applications?

A: Yes, provided the application voltage does not exceed 3000V. The substitute part meets or exceeds all mandatory compatibility parameters including capacitance value, package format, operating temperature range, and compliance certifications. The higher voltage rating and improved tolerance are backward-compatible with designs specified for the original part.

Q: What is the difference between X7R and C0G temperature coefficients?

A: X7R and C0G (NP0) are both acceptable temperature coefficient classifications for general-purpose applications. X7R provides moderate capacitance stability across the -55°C to 125°C range. C0G/NP0 offers superior temperature stability with minimal capacitance drift. Both maintain the required -55°C ~ 125°C operating temperature range.

Q: Are there physical compatibility concerns between these parts?

A: Both components use the 1808 (4520 Metric) package format with identical thickness (0.071" / 1.80mm). Minor length variations (4.60mm vs. 4.50mm) and width consistency (2.00mm) present no PCB layout or assembly compatibility issues.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity rating, requiring identical moisture control, storage, and handling protocols during manufacturing and assembly.

Q: What compliance certifications apply to both parts?

A: Both the 1808SC330MAT1A and C4520C0G3F330K160KA are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0020.
