Engineering Selection Recommendations

KYOCERA AVX KGM21NR72D102MT: Direct functional equivalent to 08052C102MA12A with identical electrical specifications (1000 pF, ±20%, 200V, X7R). Offers ROHS3 compliance and reduced thickness (0.039" vs 0.037"), improving PCB assembly compatibility. Recommended for new designs requiring regulatory compliance.

KYOCERA AVX KGM21NR72D102KT: Suitable where ±10% tolerance is acceptable. Maintains 200V rating and X7R temperature coefficient with ROHS3 compliance. Provides tighter tolerance specification with no performance compromise.

KYOCERA AVX KGM21NR72E102KT: Specified for applications requiring 250V rated voltage with ±10% tolerance. ROHS3 compliant. Provides enhanced voltage margin for designs operating near maximum rated voltage of 08052C102MA12A.

KEMET C0805C102M2RAC7800: Cross-manufacturer equivalent with identical electrical specifications and ROHS3 compliance. Thickness of 0.035" is thinner than original part, beneficial for space-constrained designs. Suitable for direct substitution in production.

Knowles 0805B102K501NT and 0805J5000102KJT/KXT: Specified for applications requiring 500V rated voltage. Both manufacturers offer ROHS3 compliance. Increased thickness (0.051" to 0.054") must be verified against PCB assembly constraints. Recommended only when higher voltage margin is required.

Frequently Asked Questions (FAQ)

Q: Can KGM21NR72D102MT be used as a direct replacement for 08052C102MA12A?

A: Yes. Both parts have identical capacitance (1000 pF), tolerance (±20%), voltage rating (200V), and temperature coefficient (X7R). The KGM part offers improved regulatory compliance (ROHS3) and reduced thickness, making it suitable for direct substitution in new designs.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides near-zero temperature coefficient, maintaining stable capacitance across temperature extremes. C0G/NP0 is specified for precision applications where temperature stability is critical.

Q: Can I use a 250V or 500V rated part in place of the 200V rated 08052C102MA12A?

A: Yes, provided all other electrical parameters match. Higher voltage ratings provide additional design margin and are electrically compatible. However, verify that increased thickness (0.051" to 0.054" for 500V parts) does not conflict with PCB assembly constraints or board layout requirements.

Q: Are all substitute parts ROHS3 compliant?

A: No. The original 08052C102MA12A is RoHS non-compliant. All KYOCERA AVX KGM series, KEMET C0805C series, and Knowles parts listed are ROHS3 compliant. Verify compliance requirements for your application before selection.

Q: What is the impact of tolerance differences (±5%, ±10%, ±20%)?

A: Tighter tolerance (±5%, ±10%) provides more precise capacitance values within specified range. For general-purpose applications, ±20% tolerance is acceptable. Specify tighter tolerance only when circuit design requires capacitance precision.

Q: Can thickness variation affect PCB assembly?

A: Yes. Original part thickness is 0.037" (0.94mm). Substitute parts range from 0.035" to 0.054". Verify that selected part thickness is compatible with PCB assembly equipment, solder reflow profiles, and board layout constraints before implementation.

Q: Are Knowles Novacap and Knowles Syfer parts interchangeable?

A: Both manufacturers produce equivalent 1000 pF 500V X7R 0805 capacitors. Electrical specifications are identical. Thickness differs slightly (0.054" vs 0.051"). Verify with assembly documentation that selected part meets mechanical constraints.
