Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1206J0250183KXT is determined by the following mandatory parameters:

• Capacitance value must equal 0.018 µF
• Temperature coefficient must be X7R
• Package must be 1206 (3216 Metric)
• Mounting type must be Surface Mount, MLCC
• Operating temperature range must span -55°C to 125°C
• Voltage rating may be equal to or greater than 25V
• Tolerance may be equal to or tighter than ±10%
• RoHS3 compliance and MSL 1 rating must be maintained

Three substitute parts meet these criteria. Two parts offer higher voltage ratings (50V and 100V) with maintained or improved tolerance specifications. One part provides a 100V rated alternative from a different manufacturer.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage processes.

C1206C183J5RAC7800 provides a 50V rated option with improved ±5% tolerance, suitable for applications requiring higher voltage margin while maintaining tighter capacitance specification.

C1206C183K1RAC7800 and KGM31BR72A183KT both provide 100V rated alternatives with ±10% tolerance matching the original specification. C1206C183K1RAC7800 offers significantly higher inventory availability (6029 units) compared to the main part. KGM31BR72A183KT provides an alternative from KYOCERA AVX with comparable specifications and substantial stock (7283 units).

Selection between 50V and 100V rated substitutes depends on circuit voltage requirements. Both voltage options are electrically interchangeable with the 25V rated main part in applications operating at or below 25V.

Frequently Asked Questions (FAQ)

Can C1206C183J5RAC7800 replace 1206J0250183KXT directly?

Yes. The 50V rating exceeds the original 25V specification, and the ±5% tolerance is tighter than the original ±10%. All other parameters including capacitance, temperature coefficient, package, and operating range are identical.

What is the difference between the two KEMET substitutes?

C1206C183J5RAC7800 is rated 50V with ±5% tolerance. C1206C183K1RAC7800 is rated 100V with ±10% tolerance. Both are electrically interchangeable with the original part. The 100V option provides greater voltage margin.

Can KGM31BR72A183KT be used instead of the KEMET parts?

Yes. KGM31BR72A183KT from KYOCERA AVX meets all substitution criteria with identical capacitance, temperature coefficient, package, and operating temperature range. The 100V rating and ±10% tolerance match the electrical requirements.

Are there packaging differences between these parts?

The main part is supplied in Tape & Reel (TR) packaging. C1206C183J5RAC7800 is supplied in Cut Tape (CT) packaging. C1206C183K1RAC7800 and KGM31BR72A183KT are supplied in Tape & Reel (TR) packaging. Packaging format does not affect electrical performance or component compatibility.

Which substitute offers the best availability?

KGM31BR72A183KT has the highest inventory at 7283 units, followed by C1206C183K1RAC7800 at 6029 units. Both significantly exceed the main part inventory of 1088 units.
