Substitute Part Grouping Explanation

Substitution of the 06033C391MAT2A is determined by the following criteria:

Fixed Parameters (Must Match):

Capacitance: 390 pF
Package / Case: 0603 (1608 Metric)
Mounting Type: Surface Mount, MLCC
Operating Temperature Range: -55°C ~ 125°C

Variable Parameters (Allowed to Differ):

Voltage Rating: May be equal to or higher than 25V
Tolerance: May be tighter (lower) than ±20%
Temperature Coefficient: X7R or C0G/NP0 acceptable
Manufacturer: KYOCERA AVX or KEMET

Substitute parts are grouped into two categories: (1) KYOCERA AVX X7R variants with higher voltage ratings and improved tolerance, and (2) KYOCERA AVX and KEMET C0G/NP0 variants offering superior temperature stability and tighter tolerance specifications.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance.

X7R Dielectric Substitutes (06031C391JAT2A, 06031C391KAT2A, 06035C391JAT2A, C0603C391J5RAC7867): These parts preserve the X7R temperature coefficient of the original 06033C391MAT2A while offering higher voltage ratings (50V or 100V) and improved tolerance specifications (±5% to ±10%). Selection depends on circuit voltage requirements and tolerance budget.

C0G/NP0 Dielectric Substitutes (KGM15ACG1E391FT, KGM15ACG1H391FT, KGM15ACG1H391GT, C0603C391F5GAC7867, C0603C391G5GAC7867, C0603C391J1GAC7867): These parts provide superior temperature stability through C0G/NP0 dielectric with tolerance specifications of ±1% to ±2%, suitable for precision applications requiring minimal capacitance drift across the operating temperature range. Voltage ratings range from 25V to 100V.

Manufacturer Considerations: KYOCERA AVX and KEMET parts are functionally equivalent within specified parameters. KEMET C0603C series includes Low ESL feature designation.

Frequently Asked Questions (FAQ)

Q: Can I substitute 06033C391MAT2A with a higher voltage rated part? A: Yes. Higher voltage ratings (50V or 100V) are acceptable substitutes provided capacitance (390 pF), package (0603), and operating temperature range (-55°C to 125°C) remain unchanged. Circuit voltage requirements determine the minimum acceptable voltage rating.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R dielectric exhibits capacitance variation of ±15% across the -55°C to 125°C operating range. C0G/NP0 dielectric provides superior stability with minimal capacitance drift. C0G/NP0 substitutes are appropriate for precision circuits requiring stable capacitance values across temperature extremes.

Q: Are tolerance differences significant for this 390 pF capacitor? A: The original part specifies ±20% tolerance. Tighter tolerances (±1%, ±2%, ±5%, ±10%) available in substitute parts reduce capacitance variation and improve circuit predictability. Selection depends on circuit design requirements and tolerance budget.

Q: Can KEMET parts directly replace KYOCERA AVX parts? A: Yes. KEMET C0603C series parts with matching capacitance, voltage, package, and temperature coefficient are direct functional equivalents. Both manufacturers provide ROHS3 compliance and MSL 1 rating.

Q: Does package size differ between manufacturers? A: All listed parts use 0603 (1608 Metric) package. Physical dimensions are equivalent: 0.063" L x 0.031-0.032" W with maximum thickness of 0.034-0.035". Parts are mechanically interchangeable on PCB layouts designed for 0603 components.

Q: What inventory considerations apply to these substitutes? A: Substitute parts show varying inventory levels. 06031C391KAT2A (21,281 pcs), KGM15ACG1H391GT (22,986 pcs), and C0603C391F5GAC7867 (101,744 pcs) demonstrate high availability. Selection may consider supply chain continuity and lead time requirements.
