1808GC152MAT1A Equivalent & Substitute Parts

Part Overview

The 1808GC152MAT1A is a 1500 pF ceramic capacitor rated for 2000V (2kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and carries MSL 1 rating, indicating unlimited moisture sensitivity protection. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or design flexibility needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808GC152MAT1A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1500 pF (exact match required)
• Voltage Rating: 2000V (2kV) minimum (equal or higher acceptable)
• Temperature Coefficient: X7R (required for temperature stability)
• Package / Case: 1808 (4520 Metric) (required for mechanical fit)
• Mounting Type: Surface Mount, MLCC (required for assembly compatibility)
• Operating Temperature Range: -55°C ~ 125°C (required for application environment)

Flexible Parameters:

• Tolerance: ±20% or tighter (±10%) acceptable
• Thickness: Variations within mechanical constraints acceptable
• Manufacturer: Different manufacturers acceptable if all mandatory parameters match

The substitute parts listed below meet all mandatory matching parameters and are therefore electrically and mechanically compatible with the 1808GC152MAT1A.

Parameter Comparison

Engineering Selection Recommendations

1808GC152KAT1A (KYOCERA AVX Upgrade): This part offers improved tolerance specification (±10% versus ±20%), providing tighter capacitance control while maintaining identical electrical ratings and mechanical dimensions. Both parts are manufactured by KYOCERA AVX and carry identical compliance certifications (ROHS3, MSL 1). Selection of this upgrade part is appropriate when tighter capacitance tolerance is required for circuit performance without any design modifications.

CHV1808N2K0152MXT (Cal-Chip Electronics Direct Substitute): This part maintains identical electrical specifications and package dimensions as the main part, with matching ±20% tolerance. The thickness specification is 0.087" (2.20mm) compared to 0.071" (1.80mm) for the main part. This thickness difference must be evaluated against available PCB assembly clearance. The part carries identical compliance certifications (ROHS3, MSL 1) and is manufactured by Cal-Chip Electronics, Inc. This substitute is appropriate when inventory availability or lead time considerations are primary factors, provided mechanical clearance accommodates the increased thickness.

All three parts are active products with current manufacturing status and full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can 1808GC152KAT1A be used as a direct replacement for 1808GC152MAT1A?

A: Yes. Both parts share identical capacitance (1500 pF), voltage rating (2000V), temperature coefficient (X7R), package (1808), and operating temperature range (-55°C to 125°C). The 1808GC152KAT1A offers tighter tolerance (±10% versus ±20%), which is a performance improvement. No circuit modifications are required.

Q: What is the significance of the thickness difference between 1808GC152MAT1A (1.80mm) and CHV1808N2K0152MXT (2.20mm)?

A: The thickness difference of 0.40mm must be verified against available PCB assembly clearance. If the design includes height-constrained areas or proximity to other components, the increased thickness of CHV1808N2K0152MXT may create mechanical conflicts. Verify clearance before selection.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts carry ROHS3 compliance certification and are suitable for applications requiring RoHS compliance.

Q: What does MSL 1 rating mean for these capacitors?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited moisture sensitivity protection. These parts do not require special moisture control during storage or handling and can be stored under standard conditions without desiccant packaging.

Q: Can CHV1808N2K0152MXT replace 1808GC152MAT1A in all applications?

A: Electrical compatibility is confirmed. Mechanical compatibility requires verification of PCB clearance due to the 0.40mm thickness increase. Once clearance is confirmed, CHV1808N2K0152MXT is a valid substitute.

Q: Which substitute part offers the best availability?

A: CHV1808N2K0152MXT has the highest inventory level (10922 Pcs) compared to 1808GC152KAT1A (1688 Pcs) and the main part 1808GC152MAT1A (638 Pcs). Selection based on availability should be balanced against mechanical clearance requirements.
