Engineering Selection Recommendations

All listed KEMET substitutes are active products with ROHS3 compliance, providing superior availability and regulatory alignment compared to the obsolete KYOCERA AVX 61V102MCFIA. Selection among substitute options depends on specific application requirements:

C901U Series (Y5V Temperature Coefficient): C901U102MUVDAAWL20 and C901U102MUVDAAWL45 offer the smallest physical diameter (7.00mm) with Y5V stability. C901U102MVVDAAWL20 and C901U102MVVDAAWL45 provide identical electrical performance with Y5V coefficient. These are suitable for space-constrained applications.

C911U Series (Y5U Temperature Coefficient): C911U102MUWDAAWL20, C911U102MUWDAAWL45, C911U102MVWDAAWL20, and C911U102MVWDAAWL45 feature 8.00mm diameter with Y5U stability. These represent a mid-range option between compact and larger packages.

C941U Series (Y5P Temperature Coefficient, ±10% Tolerance): C941U102KUYDAAWL20 and C941U102KUYDAAWL45 provide tighter ±10% tolerance with Y5P coefficient and 11.00mm diameter. These are appropriate for applications requiring enhanced tolerance specifications.

All substitutes maintain identical 400VAC rating, X1/Y1 safety certifications, 10.00mm lead spacing, and -40°C to 125°C operating range. Physical diameter variations (7.00mm, 8.00mm, 11.00mm) require PCB layout verification to ensure mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can I use any of these KEMET substitutes interchangeably with the KYOCERA AVX 61V102MCFIA?

A: All listed KEMET parts meet the critical electrical specifications (1000 pF, ±20% or tighter tolerance, 400VAC, X1/Y1 ratings, -40°C to 125°C operation). However, physical diameter differences (7.00mm, 8.00mm, or 11.00mm versus the original 9.00mm) require PCB layout verification. Lead spacing remains constant at 10.00mm across all options.

Q: What is the difference between Y5V, Y5U, and Y5P temperature coefficients?

A: These designations define capacitance stability across the operating temperature range. Y5V (F) provides ±15% maximum variation, Y5U (E) provides ±22% maximum variation, and Y5P (B) provides ±10% maximum variation. All are acceptable for the specified -40°C to 125°C range in safety applications.

Q: Why do some substitutes have different lead spacing designations (20 versus 45)?

A: The "20" and "45" suffixes in part numbers indicate different lead forming specifications. Both maintain the required 0.394" (10.00mm) lead spacing for PCB compatibility. Verify with your assembly process requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All KEMET C900AH series substitutes listed are ROHS3 compliant, providing regulatory alignment for current manufacturing standards. The original KYOCERA AVX part does not specify RoHS status.

Q: What inventory levels are available for these substitutes?

A: Inventory varies by part number, ranging from 665 to 1143 pieces in stock across the substitute options. C901U102MVVDAAWL20, C901U102MVVDAAWL45, and C911U102MVWDAAWL20 show the highest availability.

Q: Can I substitute a part with ±10% tolerance (C941U series) for the original ±20% specification?

A: Yes. Tighter tolerance is a valid substitution. The C941U series with ±10% tolerance exceeds the original ±20% requirement and is suitable for applications where enhanced tolerance control is beneficial or required.
