Key Parameters

Substitute Part Grouping Explanation

The C1210C824K5RAC7800 manufactured by KEMET qualifies as a substitute part based on the following alignment of critical parameters:

• Capacitance value: 0.82 µF (identical)
• Tolerance: ±10% (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 1210 (3225 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The substitute part carries a higher voltage rating (50V versus 25V), which represents an upgrade capability and does not restrict substitution in applications designed for the original 25V specification.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active production status and carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification). The C1210C824K5RAC7800 substitute provides equivalent electrical performance with a reduced maximum thickness (0.047" versus 0.060"), which may offer design flexibility in space-constrained applications. The elevated voltage rating of the substitute part does not introduce incompatibility and provides additional safety margin in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the C1210C824K5RAC7800 be used as a direct replacement for the 12103C824KAT2A?

A: Yes. Both parts share identical capacitance (0.82 µF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (1210 / 3225 Metric), and physical footprint dimensions (0.126" L x 0.098" W). The substitute carries a higher voltage rating (50V versus 25V), which does not restrict its use in 25V-rated applications.

Q: Are there any physical compatibility concerns?

A: The substitute part has a reduced maximum thickness (0.047" versus 0.060"), which is compatible with standard 1210 package footprints. No PCB layout modifications are required.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 ECCN. Moisture sensitivity level is identical (MSL 1 / Unlimited) for both parts.

Q: What is the primary difference between these parts?

A: The C1210C824K5RAC7800 is rated for 50V operation compared to the 25V rating of the 12103C824KAT2A. All other electrical and mechanical specifications are equivalent.
