1808HA101MAT1A Equivalent & Substitute Parts

Part Overview

The 1808HA101MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 100 pF, rated voltage of 3000V (3kV), and C0G/NP0 temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is currently in active production status with 1154 units in stock. Equivalent and substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance, temperature coefficient) and mechanical specifications (package type, dimensions) align within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808HA101MAT1A is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance value must be 100 pF
• Voltage rating must be 3000V (3kV) or higher
• Temperature coefficient must be C0G/NP0 or X7R (both acceptable for general-purpose high-voltage applications)
• Operating temperature range must encompass -55°C to 125°C
• Tolerance must be ±20% or tighter (±10% is acceptable)

Mechanical Compatibility Requirements:

• Package designation must be 1808 (4520 Metric)
• Mounting type must be Surface Mount, MLCC
• Physical dimensions must be compatible with 1808 footprint specifications

Compliance Requirements:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited) required
• REACH Unaffected status required

Two substitute parts meet these criteria: the TDK Corporation C4520C0G3F101K200KA (upgrade substitute with improved tolerance) and the KEMET C1808C101KHRAC7800 (manufacturer-recommended substitute with alternative temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

C4520C0G3F101K200KA (TDK Corporation) - Upgrade Substitute: This part provides direct electrical and mechanical compatibility with improved tolerance specification (±10% versus ±20%). Both parts maintain identical C0G/NP0 temperature coefficient characteristics, ensuring equivalent frequency stability and temperature performance. Dimensional variations are within 1808 package tolerances. All compliance certifications (ROHS3, REACH Unaffected) are maintained. This substitute is suitable for applications where tighter capacitance tolerance is beneficial. Inventory availability is higher (3400 units).

C1808C101KHRAC7800 (KEMET) - Manufacturer-Recommended Substitute: This part meets all electrical requirements with 100 pF capacitance at 3000V rating and ±10% tolerance. The primary difference is the X7R temperature coefficient instead of C0G/NP0. X7R provides broader temperature stability characteristics suitable for general-purpose applications. The part features lower ESL (Equivalent Series Inductance) and reduced thickness (0.069" versus 0.087"), which may provide advantages in high-frequency or space-constrained designs. All compliance certifications are maintained. This substitute is designated as manufacturer-recommended and carries 2948 units in inventory.

Frequently Asked Questions (FAQ)

Q: Can I use the TDK C4520C0G3F101K200KA as a direct replacement for the KYOCERA AVX 1808HA101MAT1A?

A: Yes. Both parts share identical capacitance (100 pF), voltage rating (3000V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 1808 package designation. The TDK part offers improved tolerance (±10% versus ±20%), which is a performance upgrade. Dimensional variations are within package specifications.

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

A: C0G/NP0 provides near-zero capacitance change across the operating temperature range, ensuring stable performance in precision applications. X7R provides broader temperature stability with specified capacitance variation limits. Both are acceptable for general-purpose high-voltage applications. Selection depends on circuit requirements for capacitance stability.

Q: Are the physical dimensions of all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 1808 (4520 Metric) package designation. Length variations (4.50mm to 4.70mm) and thickness variations (1.75mm to 2.20mm) are within standard 1808 package tolerances and compatible with standard 1808 footprints. Verify specific PCB layout constraints for height-sensitive applications.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). All parts are in active production status with current inventory availability.

Q: Which substitute should I select for a new design?

A: Selection depends on specific application requirements. For direct replacement with improved tolerance, use the TDK C4520C0G3F101K200KA. For manufacturer-recommended substitution with lower ESL and reduced height, use the KEMET C1808C101KHRAC7800. Both are electrically and mechanically compatible with the original 1808HA101MAT1A specification.
