KYOCERA AVX 1808GC102MATBE Equivalent & Substitute Parts

Part Overview

The 1808GC102MATBE is a 1000 pF ±20% 2000V (2kV) ceramic capacitor with X7R temperature coefficient in 1808 (4520 Metric) surface mount package. This high-voltage MLCC is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Finding equivalent and substitute parts is necessary to address inventory availability, packaging requirements, tolerance specifications, and voltage rating options across multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the 1808GC102MATBE is determined by the following critical parameters: capacitance value (1000 pF), temperature coefficient (X7R), package size (1808/4520 Metric), mounting type (surface mount MLCC), and operating temperature range (-55°C to 125°C). Parts are grouped into three categories based on functional compatibility:

Direct Equivalents (Same Tolerance & Voltage): Parts with identical ±20% tolerance and 2000V rating maintain full electrical and mechanical compatibility with the original specification.

Upgrade Options (Improved Tolerance): Parts with ±10% tolerance provide tighter capacitance control while maintaining the same 2000V rating and package footprint. These are direct functional upgrades.

Voltage Upgrades: Parts rated at 2500V or 3000V provide higher voltage margins while maintaining 1000 pF capacitance and X7R characteristics. These are suitable for applications requiring enhanced voltage headroom.

Cross-Manufacturer Equivalents: Parts from TDK, YAGEO, and KEMET with identical electrical specifications and 1808 package size provide alternative sourcing options.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): Select 1808GC102MAT1A (KYOCERA AVX) or CC1808MKX7RDBB102 (YAGEO) when ±20% tolerance and 2000V rating are required. Both parts are active products with ROHS3 compliance and MSL 1 rating. The KYOCERA AVX option provides higher inventory availability (6100 Pcs).

For Improved Tolerance Performance: Select 1808GC102KAT1A or KGM42CR73D102KY (both KYOCERA AVX) when ±10% tolerance is required at 2000V. KGM42CR73D102KY offers the highest inventory (9025 Pcs) and is suitable for applications requiring tighter capacitance control.

For Enhanced Voltage Margin: Select 1808HC102KAT1A (3000V) or 1808WC102KAT1A (2500V) when higher voltage headroom is necessary. Both maintain 1000 pF capacitance and ±10% tolerance with active product status.

Cross-Manufacturer Selection: C1808C102KGRAC7800 (KEMET) provides an alternative source with ±10% tolerance, 2000V rating, and active product status. This part is suitable for multi-source supply chain strategies.

Avoid: C4520X7R3D102M130KA (TDK) 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 substitute 1808GC102MATBE with a ±10% tolerance part? A: Yes. Parts such as 1808GC102KAT1A, KGM42CR73D102KY, and C1808C102KGRAC7800 provide ±10% tolerance while maintaining identical 1000 pF capacitance, 2000V rating, X7R temperature coefficient, and 1808 package size. These are functional upgrades with tighter capacitance control.

Q: What is the difference between KGM42CR73D102MY and KGM42CR73D102KY? A: Both are KYOCERA AVX KGM series parts with 1000 pF, 2000V, and X7R specifications. KGM42CR73D102MY has ±20% tolerance (direct equivalent), while KGM42CR73D102KY has ±10% tolerance (upgrade). The KY variant provides improved tolerance performance.

Q: Can I use a 3000V rated part instead of 2000V? A: Yes. Parts rated at 3000V (1808HC102KAT1A, KGM42CR73U102KY) are suitable replacements as they maintain the same 1000 pF capacitance, X7R temperature coefficient, and 1808 package. Higher voltage rating provides additional safety margin without affecting electrical performance at 2000V operation.

Q: Are there thickness differences between substitute parts? A: Yes. The original 1808GC102MATBE has 0.071" thickness. Some substitutes such as KGM42CR73D102MY, 1808HC102KAT1A, and CC1808MKX7RDBB102 have 0.087" thickness. Verify PCB layout clearance before selection. KEMET C1808C102KGRAC7800 offers 0.069" thickness for space-constrained applications.

Q: Which substitute offers the best inventory availability? A: KGM42CR73D102KY (KYOCERA AVX) provides the highest inventory at 9025 Pcs with ±10% tolerance and 2000V rating. For ±20% tolerance equivalents, 1808GC102MAT1A offers 6100 Pcs.

Q: Is the TDK C4520X7R3D102M130KA suitable for new designs? A: No. This part is marked "Not For New Designs" and should not be selected for new applications. Use active alternatives such as KYOCERA AVX or YAGEO equivalents instead.

Q: Do all substitute parts have the same RoHS and MSL compliance? A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating, matching the original 1808GC102MATBE specifications.
