1808SC101MAT1A Equivalent & Substitute Parts

Part Overview

The 1808SC101MAT1A is a 100 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) operation with X7R temperature coefficient characteristics. This surface mount multilayer ceramic capacitor (MLCC) in 1808 (4520 Metric) package is designed for general purpose high voltage applications. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance is required, inventory availability is a consideration, or when design specifications allow for enhanced voltage ratings or improved tolerance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC101MAT1A is determined by the following mandatory parameters:

• Capacitance Value: Must be 100 pF (exact match required)
• Package / Case: Must be 1808 (4520 Metric) form factor
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Voltage Rating: Must meet or exceed 1500V (1.5kV)
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Two substitute parts meet these criteria with enhanced electrical characteristics:

C1808C101KHRAC7800 (KEMET): Maintains identical capacitance, package, and mounting specifications while providing doubled voltage rating (3000V) and improved tolerance (±10% vs ±20%). Temperature coefficient remains X7R with equivalent operating range.

C4520C0G3F101K200KA (TDK Corporation): Maintains identical capacitance, package, and mounting specifications with doubled voltage rating (3000V) and improved tolerance (±10%). Temperature coefficient differs to C0G/NP0, providing superior temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity ratings, ensuring regulatory and environmental compatibility across applications.

C1808C101KHRAC7800 (KEMET) provides direct functional upgrade with maintained X7R temperature coefficient performance, doubled voltage margin, and tighter tolerance specification. Dimensional variance is minimal (0.185" vs 0.181" length, 0.069" vs 0.071" thickness), suitable for most PCB layouts with standard 1808 footprints.

C4520C0G3F101K200KA (TDK Corporation) offers superior temperature stability through C0G/NP0 temperature coefficient with equivalent voltage upgrade and tolerance improvement. Thickness increases to 0.087" (2.20mm maximum), requiring verification against available PCB assembly clearance. This variant is appropriate for applications requiring minimal capacitance drift across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can C1808C101KHRAC7800 or C4520C0G3F101K200KA be used as direct replacements for 1808SC101MAT1A?

A: Both parts are electrically compatible substitutes. The 1808 (4520 Metric) package footprint is identical across all three parts. Dimensional tolerances on length and thickness are within typical PCB assembly specifications. Verify available clearance for the TDK part, which has maximum thickness of 0.087" compared to 0.071" for the original.

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

A: X7R provides ±15% capacitance variation across -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance drift across temperature. Selection depends on circuit requirements for capacitance tolerance over temperature.

Q: Why do the substitute parts have higher voltage ratings?

A: The substitute parts (3000V) provide doubled voltage margin compared to the original (1500V). This allows use in higher voltage applications or provides additional safety margin in existing 1500V designs. Capacitance and tolerance values remain identical.

Q: Are there packaging differences between these parts?

A: The original is supplied in standard packaging. KEMET C1808C101KHRAC7800 is supplied in Tape & Reel (TR). TDK C4520C0G3F101K200KA is supplied in Cut Tape (CT) & Digi-Reel®. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Do all three parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. All maintain MSL 1 (unlimited) moisture sensitivity rating, eliminating bake-out requirements for storage and handling.
