1808SA101MAT1A Equivalent & Substitute Parts

Part Overview

The 1808SA101MAT1A is a 100 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V (1.5kV) with C0G/NP0 temperature coefficient in 1808 (4520 Metric) surface mount package. This component is classified as Active and maintains 1037 units in current inventory stock. The part is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

Substitute parts are identified when equivalent electrical performance can be maintained or enhanced while preserving mechanical compatibility and compliance requirements. Alternative sources become necessary for supply chain optimization, extended lead times, or design flexibility across manufacturing partners.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SA101MAT1A is determined by the following mandatory parameters:

• Capacitance Value: Must be 100 pF
• Package / Case: Must be 1808 (4520 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• 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 or equivalent electrical specifications:

C4520C0G3F101K200KA (TDK Corporation) provides voltage rating upgrade to 3000V (3kV) while maintaining identical capacitance, package, and temperature range. Temperature coefficient remains C0G/NP0 with improved tolerance (±10%).

C1808C101KHRAC7800 (KEMET) provides voltage rating upgrade to 3000V (3kV) with alternative temperature coefficient (X7R) and improved tolerance (±10%). This part introduces Low ESL characteristics while maintaining package and temperature range compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as Active products with full ROHS3 compliance and MSL 1 rating, matching the regulatory and environmental requirements of the original 1808SA101MAT1A.

C4520C0G3F101K200KA (TDK Corporation) maintains identical temperature coefficient classification (C0G/NP0) with doubled voltage rating capability. This part is suitable for applications where temperature coefficient stability is a primary design requirement and voltage margin enhancement is beneficial. Tolerance improvement from ±20% to ±10% provides tighter capacitance control.

C1808C101KHRAC7800 (KEMET Corporation) offers voltage rating upgrade with X7R temperature coefficient and Low ESL characteristics. This part is suitable for applications where ESL performance is advantageous and X7R temperature stability meets design specifications. Tolerance improvement to ±10% and reduced thickness (1.75mm vs. 1.45mm original) should be evaluated against PCB layout constraints.

All three parts maintain identical capacitance value, package footprint compatibility, and operating temperature range. Selection between substitutes depends on specific application requirements regarding temperature coefficient type and ESL performance.

Frequently Asked Questions (FAQ)

Q: Can C4520C0G3F101K200KA replace 1808SA101MAT1A in all applications?

A: C4520C0G3F101K200KA is mechanically and electrically compatible as a direct substitute. Both parts share identical capacitance (100 pF), package (1808/4520 Metric), temperature range (-55°C ~ 125°C), and temperature coefficient (C0G/NP0). The substitute provides enhanced voltage rating (3000V vs. 1500V) and improved tolerance (±10% vs. ±20%). Dimensional variations are minimal (length 4.50mm vs. 4.60mm; thickness 2.20mm vs. 1.45mm) and should be evaluated against PCB layout requirements.

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

A: C0G/NP0 provides superior temperature stability with minimal capacitance variation across the operating range. X7R allows greater capacitance variation with temperature but offers higher volumetric efficiency. Selection depends on application sensitivity to capacitance drift. The KEMET substitute (C1808C101KHRAC7800) uses X7R; the TDK substitute (C4520C0G3F101K200KA) maintains C0G/NP0 matching the original part.

Q: Are there physical size constraints when substituting these parts?

A: All three parts use the 1808 (4520 Metric) package with compatible footprints. Length variations range from 4.50mm to 4.70mm and width is uniform at 2.00mm. Thickness varies from 1.45mm (original) to 2.20mm (TDK substitute). PCB layout clearance and component height restrictions should be evaluated before selection, particularly for the TDK part with maximum thickness of 2.20mm.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. Both C4520C0G3F101K200KA and C1808C101KHRAC7800 are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original 1808SA101MAT1A. All parts are classified as Active products with current manufacturing support.

Q: What is the inventory status of substitute parts?

A: C4520C0G3F101K200KA (TDK) has 3400 units in stock. C1808C101KHRAC7800 (KEMET) has 2948 units in stock. Both substitutes maintain higher inventory levels than the original part (1037 units).
