Substitute Part Grouping Explanation

Substitution for the 12103C274MAT2A is determined by the following criteria:

• Capacitance value must remain 0.27 µF
• Package must be 1210 (3225 Metric) surface mount
• Temperature coefficient must be X7R
• Operating temperature range must be -55°C ~ 125°C
• Rated voltage may be equal to or greater than 25V
• Tolerance may vary (±5%, ±10%, ±20%)
• Manufacturer may differ
• RoHS3 compliance and MSL 1 rating must be maintained

Substitute parts identified meet all mandatory criteria while offering higher voltage ratings or improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance. Selection between substitutes depends on application voltage requirements and tolerance specifications:

12105C274JAT2A offers the tightest tolerance at ±5% with 50V rating, suitable for applications requiring improved capacitance accuracy.

12105C274KAT2A provides ±10% tolerance with 50V rating, balancing tolerance performance with cost considerations.

C1210C274K5RAC7800 from KEMET offers ±10% tolerance with 50V rating and represents a cross-manufacturer alternative. Maximum thickness is 0.039" (1.00mm) compared to 0.037" (0.94mm) for KYOCERA AVX parts; verify PCB assembly clearance requirements.

All substitutes are electrically compatible with the original 12103C274MAT2A in applications where 25V minimum rating is required.

Frequently Asked Questions (FAQ)

Can 12105C274JAT2A replace 12103C274MAT2A directly?

Yes. Both parts share identical capacitance (0.27 µF), package (1210), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). The 12105C274JAT2A provides higher voltage rating (50V vs 25V) and tighter tolerance (±5% vs ±20%), making it a direct upgrade.

What is the difference between 12105C274JAT2A and 12105C274KAT2A?

Both are KYOCERA AVX 0.27 µF 50V X7R 1210 capacitors. The primary difference is tolerance: 12105C274JAT2A is ±5% while 12105C274KAT2A is ±10%. Select based on application tolerance requirements.

Can KEMET C1210C274K5RAC7800 be used instead of KYOCERA AVX parts?

Yes, with one consideration. The C1210C274K5RAC7800 has maximum thickness of 0.039" (1.00mm) versus 0.037" (0.94mm) for KYOCERA AVX parts. Verify PCB assembly height clearance before substitution.

Are all substitute parts ROHS3 compliant?

Yes. All identified substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specifications.

What voltage rating should I select?

The original 12103C274MAT2A is rated 25V. All substitutes are rated 50V, providing higher voltage margin. Select based on your circuit's maximum operating voltage. Higher voltage rating does not negatively affect performance in lower voltage applications.
