Engineering Selection Recommendations

For Direct Substitution (No Circuit Redesign Required):

Use KGM42CCG3A102KY when the original 1808AA102MATRE is unavailable. This part maintains identical electrical specifications (1000 pF, 1000V, C0G/NP0) with improved tolerance (±10% vs ±20%), same package footprint, and equivalent thickness. All compliance certifications match: ROHS3, MSL 1, REACH Unaffected.

For Voltage Margin Enhancement:

When circuit design permits higher voltage ratings, select from the X7R temperature coefficient series:

1808AC102KAT1A for 1000V requirement with X7R stability
1808SC102KAT1A for 1500V margin
1808GC102KAT1A or C4520X7R3D102K130KA for 2000V margin
1808HC102KAT1A for 3000V margin

All X7R variants maintain ±10% tolerance, -55°C to 125°C operating range, and ROHS3 compliance. Note: X7R temperature coefficient exhibits wider capacitance variation across temperature range compared to C0G/NP0.

For Cross-Manufacturer Sourcing:

KEMET C1808C102KGRAC7800 and TDK C4520X7R3A102K130KA / C4520X7R3D102K130KA provide alternative supply sources with identical package and electrical specifications. All parts maintain Active product status and full compliance certifications.

Thickness Considerations:

Original part thickness is 0.087" (2.20mm). X7R variants at 1000V and 1500V ratings are thinner at 0.071" (1.80mm), enabling tighter PCB layouts. Higher voltage X7R parts (2500V, 3000V) return to 0.087" (2.20mm) thickness. TDK parts offer minimum thickness at 0.059" (1.50mm) for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can I use KGM42CCG3A102KY as a direct replacement for 1808AA102MATRE?

A: Yes. Both parts are 1000 pF, 1000V, C0G/NP0 ceramic capacitors in 1808 package with identical dimensions and operating temperature range. KGM42CCG3A102KY offers tighter tolerance (±10% vs ±20%), which is a functional improvement. Packaging differs (Tape & Reel vs standard), but this does not affect circuit performance.

Q: What is the difference between C0G/NP0 and X7R temperature coefficients?

A: C0G/NP0 provides stable capacitance across the -55°C to 125°C operating range with minimal variation. X7R exhibits wider capacitance variation across temperature but maintains acceptable performance for general purpose applications. Both temperature coefficients are supported in this product family and maintain -55°C to 125°C operating range.

Q: Can I substitute a 2000V rated part for the 1000V original?

A: Yes, when circuit design permits. Higher voltage ratings provide additional safety margin. Parts such as 1808GC102KAT1A (2000V, X7R) or C4520X7R3D102K130KA (2000V, X7R) are electrically compatible and will function in circuits designed for 1000V operation. Verify PCB layout accommodates the package thickness variation if applicable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, matching the original 1808AA102MATRE certification profile.

Q: What is the inventory advantage of substitute parts?

A: C4520X7R3D102K130KA (TDK) offers the highest inventory at 95,140 pieces, followed by 1808GC102MAT1A (KYOCERA AVX) at 6,100 pieces. These parts provide reliable supply for high-volume production requirements.

Q: Does package thickness affect circuit performance?

A: Package thickness does not affect electrical performance. Thickness variation (0.059" to 0.087") impacts PCB layout density and component clearance. Verify mechanical fit in your specific PCB assembly before selecting thinner alternatives.
