Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Direct Equivalents maintain identical capacitance (1000 pF), tolerance (±20%), voltage rating (2000V), temperature coefficient (X7R), package (1808), and operating temperature range (-55°C ~ 125°C). These parts are functionally interchangeable with the main part.

Upgrade Equivalents improve upon the main part by offering tighter tolerance (±10% instead of ±20%), enhanced RoHS3 compliance, or REACH unaffected status, while maintaining all other core electrical parameters. These parts provide superior performance characteristics within the same package footprint.

Voltage-Upgraded Equivalents maintain all parameters except voltage rating, which is increased to 2500V or 3000V. These parts are suitable for applications requiring higher voltage margins while preserving capacitance and temperature characteristics.

Parametric Equivalents from alternative manufacturers (TDK, YAGEO, KEMET) match the electrical specifications and package requirements, offering supply chain diversity and alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Improved Compliance: Select 1808GC102MAT1A (KYOCERA AVX). This part maintains identical electrical specifications (1000 pF, ±20%, 2000V, X7R) and physical package as the main part while providing ROHS3 compliance and REACH unaffected status. Inventory availability is 6100 units.

For Tighter Tolerance Requirements: Select 1808GC102KAT1A (KYOCERA AVX) or C4520X7R3D102K130KA (TDK Corporation). Both offer ±10% tolerance instead of ±20%, with ROHS3 compliance. The TDK part has significantly higher inventory (95140 units) and active product status.

For Higher Voltage Margin Applications: Select 1808HC102KAT1A (3000V) or 1808WC102KAT1A (2500V), both from KYOCERA AVX with ±10% tolerance and ROHS3 compliance. These provide voltage headroom while maintaining the same capacitance and package.

For Multi-Source Supply Chain Diversification: Select CC1808MKX7RDBB102 (YAGEO) or C1808C102KGRAC7800 (KEMET). Both are active products with ROHS3 compliance, offering alternative manufacturer sourcing for the same electrical specifications.

Avoid: C4520X7R3D102M130KA (TDK Corporation) is marked "Not For New Designs" and should not be selected for new applications despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can I use 1808GC102MAT1A as a direct replacement for 1808GC102MAJ1A?

A: Yes. Both parts have identical electrical specifications (1000 pF, ±20%, 2000V, X7R) and package dimensions (1808). The primary difference is that 1808GC102MAT1A provides ROHS3 compliance and REACH unaffected status, making it suitable for regulated applications.

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

A: Tolerance defines the acceptable capacitance variation from the nominal value. ±20% allows variation from 800 pF to 1200 pF, while ±10% restricts variation to 900 pF to 1100 pF. Applications requiring tighter capacitance control should specify ±10% tolerance parts.

Q: Can I substitute a 3000V rated part (1808HC102KAT1A) for a 2000V rated part (1808GC102MAJ1A)?

A: Yes, from an electrical standpoint. Higher voltage rating provides additional safety margin. However, verify that the increased thickness (2.20mm vs 1.80mm) does not conflict with PCB layout constraints or assembly specifications.

Q: Why is C4520X7R3D102M130KA marked "Not For New Designs"?

A: This designation indicates the manufacturer (TDK) is phasing out this part number. While existing inventory may be available, new designs should select active product status alternatives to ensure long-term supply continuity.

Q: Are all substitute parts in the same 1808 package?

A: Yes. All listed substitutes use the 1808 (4520 Metric) surface mount package. However, verify specific dimensions (length, width, thickness) as minor variations exist between manufacturers. Thickness ranges from 1.50mm to 2.20mm depending on voltage rating and manufacturer.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This applies to all listed parts.
