Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

• Capacitance value: 0.018 µF (exact match required)
• Voltage rating: 100V (exact match required)
• Temperature coefficient: X7R (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Tolerance variations (±20%, ±10%, ±5%) are permitted within the allowed electrical parameter range for this product category. Physical dimensions including thickness may vary within standard manufacturing tolerances for the 0805 package.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection between the main part and substitutes is based on tolerance requirements and physical space constraints:

C0805C183K1RAC7800 (KEMET) offers the smallest maximum thickness at 0.035" (0.88mm), suitable for applications with vertical space limitations.

KGM21AR72A183JU (KYOCERA AVX) provides the tightest tolerance at ±5%, appropriate for circuits requiring higher capacitance accuracy.

KGM21AR72A183KU (KYOCERA AVX) offers the highest inventory availability at 28,575 pieces and maintains ±10% tolerance with standard thickness specifications.

0805J1000183MXT (Knowles Syfer) remains the original specification with ±20% tolerance and standard thickness of 0.051" (1.30mm).

Frequently Asked Questions (FAQ)

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, provided the circuit design accommodates the tolerance range. All parts share identical capacitance value (0.018 µF), voltage rating (100V), temperature coefficient (X7R), package (0805), and operating temperature range (-55°C ~ 125°C).

Q: What is the significance of tolerance differences?

A: Tolerance indicates the acceptable deviation from the nominal capacitance value. ±20% allows ±0.0036 µF deviation, ±10% allows ±0.0018 µF deviation, and ±5% allows ±0.0009 µF deviation. Select based on circuit sensitivity to capacitance variation.

Q: Are there physical space considerations?

A: Yes. The KEMET C0805C183K1RAC7800 has a maximum thickness of 0.035" (0.88mm), while Knowles Syfer and KYOCERA AVX parts reach 0.051" (1.30mm) and 0.057" (1.45mm) respectively. Verify PCB layout clearance before substitution.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 with identical HTSUS code 8532.24.0020. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: Which part should be selected for general purpose applications?

A: KGM21AR72A183KU (KYOCERA AVX) is suitable for general purpose applications with the highest inventory availability and ±10% tolerance. KGM21AR72A183JU (KYOCERA AVX) is appropriate when ±5% tolerance is required.
