Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1210CC273MAT9A is determined by the following critical parameters:

• Capacitance Value: Must be 0.027 µF
• Voltage Rating: Must be 630V or higher
• Temperature Coefficient: Must be X7R
• Package: Must be 1210 (3225 metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.130" L × 0.098" W (3.30mm × 2.50mm)
• Compliance: Must maintain ROHS3 and REACH compliance status

The primary substitute identified is 1210CC273KAT1A, which maintains all critical electrical and mechanical parameters while offering improved tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 1210CC273MAT9A and 1210CC273KAT1A are active products from KYOCERA AVX with identical electrical ratings, temperature performance, and mechanical compatibility. The substitute part 1210CC273KAT1A offers tighter capacitance tolerance (±10% versus ±20%), which may provide improved circuit performance in applications requiring closer value accuracy. Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across manufacturing regions. Selection between these parts should be based on tolerance requirements and packaging format availability (the substitute is available in Tape & Reel format).

Frequently Asked Questions (FAQ)

Q: Can 1210CC273KAT1A directly replace 1210CC273MAT9A in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, temperature coefficient, package dimensions, and mounting type. The substitute offers improved tolerance specification without requiring circuit redesign.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the acceptable deviation from the nominal 0.027 µF value. The ±10% tolerance of 1210CC273KAT1A provides tighter capacitance accuracy, beneficial for applications with strict value requirements. The ±20% tolerance of 1210CC273MAT9A is acceptable for general-purpose applications with wider tolerance margins.

Q: Are there packaging differences between these parts?

A: The main part 1210CC273MAT9A is available in standard packaging, while the substitute 1210CC273KAT1A is supplied in Tape & Reel (TR) format. Both are surface-mount compatible with identical footprints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 1210CC273MAT9A and 1210CC273KAT1A are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly.
