Engineering Selection Recommendations

All listed substitute parts are active KEMET products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection among substitutes depends on physical space constraints and tolerance requirements:

C901U series (Y5V, 7.00mm diameter): Smallest physical footprint. Suitable for space-constrained applications. Maintains ±20% tolerance matching the original part.

C911U series (Y5U, 8.00mm diameter): Intermediate size. Maintains ±20% tolerance. Offers broader temperature stability characteristics within the Y5U classification.

C941U series (Y5P, 11.00mm diameter): Largest physical footprint. Provides tighter ±10% tolerance, beneficial for applications requiring improved capacitance accuracy. Requires verification of available board space.

All substitutes maintain identical lead spacing (0.394" / 10.00mm) and straight lead configuration, ensuring mechanical compatibility with existing through-hole PCB layouts. The choice between temperature coefficient variants (Y5V, Y5U, Y5P) depends on circuit performance requirements and thermal environment specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical diameter than the original 61V102MCFCA?

A: Yes. All substitute parts maintain the same lead spacing (0.394" / 10.00mm) and straight lead style required for through-hole mounting. Physical diameter differences (7.00mm, 8.00mm, or 11.00mm) do not affect electrical compatibility. Verify available PCB space before selection.

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

A: These designations define capacitance stability across the operating temperature range. All three variants maintain the required -40°C ~ 125°C operating range and X1, Y1 safety ratings. Selection depends on circuit performance requirements and thermal environment specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All KEMET substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

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

A: Yes. The ±10% tolerance of the C941U series is tighter than the original ±20% specification, making it electrically compatible. This may provide improved circuit performance in applications sensitive to capacitance variation.

Q: Are the substitute parts available in the same packaging as the original?

A: All substitute parts are supplied in bulk packaging. The original 61V102MCFCA is obsolete. Verify packaging requirements with your supplier for specific order quantities and delivery formats.
