1808SC102MAT1A Equivalent & Substitute Parts

Part Overview

The 1808SC102MAT1A is a 1000 pF ±20% 1500V (1.5kV) ceramic capacitor manufactured by KYOCERA AVX in the 1808 (4520 Metric) package. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) operates across -55°C to 125°C with X7R temperature coefficient characteristics. The part is active and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance, temperature coefficient) and mechanical specifications (package, dimensions, mounting type) align with design requirements. Alternative sources and upgraded voltage ratings provide flexibility for circuit optimization and supply chain management.

Substitute Part Grouping Explanation

Substitution is determined by strict alignment of electrical and mechanical parameters. The primary criteria are:

Electrical Parameters: Capacitance value (1000 pF), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C) must remain constant. Voltage rating may be upgraded to higher values when circuit design permits. Tolerance may vary between ±10% and ±20%.

Mechanical Parameters: Package type (1808 / 4520 Metric), mounting method (Surface Mount, MLCC), and physical dimensions must be compatible with PCB layout and assembly processes.

Compliance: All substitute parts maintain ROHS3 compliance and MSL 1 rating.

Substitute parts are grouped into two categories:

Same Voltage Rating (1500V): Direct replacements with identical voltage specification but potentially different tolerance or packaging format.
Upgraded Voltage Ratings (2000V, 2500V, 3000V): Higher voltage-rated alternatives that maintain all other electrical and mechanical specifications. These are suitable when circuit design allows for increased voltage margin.

Engineering Selection Recommendations

Direct Replacement (Same Voltage): The 1808SC102KAT1A provides direct substitution with identical 1500V rating and improved ±10% tolerance specification. Both parts are KYOCERA AVX products with ROHS3 compliance and MSL 1 rating.

Upgraded Voltage Options: Parts rated at 2000V, 2500V, and 3000V are suitable when circuit design accommodates higher voltage margins. KYOCERA AVX 1808GC102 series (2000V) and 1808HC102KAT1A (3000V) maintain standard thickness. The KGM series (KGM42CR73D102KY, KGM42CR73U102KY) offers increased thickness (0.087" / 2.21mm) with 2000V and 3000V ratings respectively.

Cross-Manufacturer Options: KEMET C1808C102KGRAC7800 (2000V) and TDK C4520X7R3D102K130KA (2000V) provide alternative sources. TDK part features reduced thickness (0.059" / 1.50mm). KEMET part specifies low ESL characteristics.

Packaging Considerations: Original part uses Tape & Reel format. Cut Tape & Digi-Reel alternatives (1808GC series, 1808HC102KAT1A, KEMET) may require different handling in automated assembly. Verify packaging compatibility with procurement and assembly processes.

Compliance: All listed substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. ECCN classification is EAR99 for all parts except KGM42CR73U102KY (HTSUS 8532.23.0020 vs. 8532.24.0020).

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct replacement?

A: Yes. A capacitor rated at 2000V, 2500V, or 3000V can replace the 1500V part when the circuit design permits. Higher voltage ratings do not affect capacitance value or temperature coefficient. Verify PCB layout accommodates any thickness variations (upgraded parts may be thicker).

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

A: Tolerance specifies the allowable deviation from the nominal 1000 pF value. ±10% tolerance (900–1100 pF) is tighter than ±20% (800–1200 pF). Select based on circuit requirements for capacitance accuracy.

Q: Are KYOCERA AVX, KEMET, and TDK parts electrically interchangeable?

A: Yes, when capacitance, voltage rating, temperature coefficient, and package specifications match. All listed parts are 1000 pF, X7R, 1808 package, and ROHS3 compliant. Physical dimensions vary slightly; verify PCB footprint compatibility.

Q: Does packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affect electrical performance?

A: No. Packaging format affects handling and assembly logistics only. Electrical specifications remain identical. Confirm your assembly equipment supports the selected packaging format.

Q: What does MSL 1 rating mean?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. The part can be stored and used without special moisture control procedures.

Q: Can I substitute the 1808SC102MAT1A with the KGM42CR73D102KY?

A: Yes, with thickness consideration. Both are 1000 pF, X7R, 1808 package, ROHS3 compliant. KGM42CR73D102KY is rated 2000V (higher margin) with ±10% tolerance and increased thickness (0.087" vs. 0.071"). Verify PCB assembly clearance.
