Substitute Part Grouping Explanation

Substitution eligibility for the 1808HC150MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 15 pF
• Voltage Rating: Must be 3000V (3kV) or higher
• Package / Case: Must be 1808 (4520 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• RoHS Compliance: Must maintain ROHS3 Compliant status
• Moisture Sensitivity Level: Must be MSL 1 (Unlimited)

The TDK Corporation part C4520C0G3F150K110KA meets all substitution criteria. While the temperature coefficient differs (C0G/NP0 versus X7R), both coefficients are acceptable for general-purpose high-voltage applications and maintain the same operating temperature range. The substitute part offers improved tolerance (±10% versus ±20%) and is available in higher inventory quantities.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808HC150MAT1A and C4520C0G3F150K110KA are active production parts with full RoHS3 compliance and REACH unaffected status. The TDK substitute part offers dimensional advantages with reduced thickness (1.30mm versus 2.20mm), which may provide benefits for space-constrained PCB layouts. The improved capacitance tolerance of ±10% in the TDK part provides tighter specification control compared to the ±20% tolerance of the KYOCERA AVX original. Both parts maintain identical voltage ratings, operating temperature ranges, and moisture sensitivity classifications, ensuring functional equivalence in general-purpose high-voltage applications. Selection between these parts should be based on inventory availability, procurement lead times, and specific tolerance requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can C4520C0G3F150K110KA be used as a direct replacement for 1808HC150MAT1A?

A: Yes. Both parts share identical capacitance (15 pF), voltage rating (3000V), operating temperature range (-55°C ~ 125°C), package designation (1808/4520 Metric), and moisture sensitivity classification (MSL 1). The parts are mechanically and electrically compatible for general-purpose applications.

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

A: X7R and C0G (NP0) are both temperature coefficient classifications for ceramic capacitors. X7R provides ±15% capacitance change across the operating temperature range, while C0G provides ±30 ppm/°C (approximately ±0.3% across the full range). Both maintain the same -55°C ~ 125°C operating temperature range and are suitable for general-purpose high-voltage applications.

Q: Are there dimensional compatibility concerns between these parts?

A: The parts have minor dimensional variations. The TDK part (C4520C0G3F150K110KA) is slightly smaller in length (4.50mm versus 4.60mm) and significantly thinner (1.30mm versus 2.20mm). These differences are within the 1808 (4520 Metric) package specification and do not affect PCB footprint compatibility. The reduced thickness of the TDK part may provide layout advantages in space-constrained designs.

Q: What is the tolerance difference between these parts?

A: The KYOCERA AVX part (1808HC150MAT1A) has ±20% tolerance, while the TDK substitute (C4520C0G3F150K110KA) has ±10% tolerance. The tighter tolerance of the TDK part provides more precise capacitance values and may be preferred in applications requiring strict component specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1808HC150MAT1A and C4520C0G3F150K110KA are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
