Substitute Part Grouping Explanation

Substitution of the 1808WA101MAT9A is permissible with components meeting the following criteria:

• Capacitance value of 100 pF
• Voltage rating equal to or greater than 2500V
• Temperature coefficient of C0G or NP0
• Operating temperature range of -55°C to 125°C or wider
• Package / Case designation of 1808 (4520 Metric)
• Surface-mount MLCC mounting type
• ROHS3 compliance and MSL 1 rating

The substitute part C4520C0G3F101K200KA from TDK Corporation satisfies all substitution criteria with an upgraded voltage rating of 3000V (3kV) and improved tolerance of ±10%.

Parameter Comparison

Engineering Selection Recommendations

The C4520C0G3F101K200KA from TDK Corporation is a direct substitute for the 1808WA101MAT9A. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The substitute part provides enhanced performance characteristics with a higher voltage rating of 3000V compared to the original 2500V specification, and improved capacitance tolerance of ±10% versus ±20%. Both components maintain identical operating temperature ranges and moisture sensitivity ratings. The physical dimensions are compatible within the 1808 (4520 Metric) package specification, with negligible differences in length (0.4mm) that do not impact PCB layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the C4520C0G3F101K200KA replace the 1808WA101MAT9A in all applications?

A: Yes. The substitute part meets or exceeds all electrical and mechanical parameters of the original component. The higher voltage rating and tighter tolerance provide equal or improved performance in applications designed for the original part.

Q: Are there physical compatibility concerns between these two parts?

A: No. Both components use the 1808 (4520 Metric) package designation with identical thickness of 0.087" (2.20mm). Length differences of 0.4mm and width differences of 0.02mm are within standard PCB layout tolerances and do not require design modifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 1808WA101MAT9A and C4520C0G3F101K200KA are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the significance of the improved tolerance specification?

A: The C4520C0G3F101K200KA offers ±10% tolerance compared to the original ±20%. This tighter tolerance reduces capacitance variation across the production range, which may improve circuit performance in applications with strict capacitance requirements.

Q: Are moisture sensitivity levels identical?

A: Yes. Both components have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
