1808SA101MAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1808SA101MAT3A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 100 pF with 1500V (1.5kV) voltage rating and C0G/NP0 temperature coefficient. This component is classified as Active and maintains full RoHS3 compliance with MSL Level 1 (Unlimited moisture sensitivity). The part is available in Surface Mount MLCC configuration with 1808 (4520 Metric) package dimensions.

Equivalent and substitute parts are identified when they maintain the same capacitance value, package form factor, and operating temperature range while meeting or exceeding the voltage rating and tolerance specifications of the original component.

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SA101MAT3A is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 100 pF (exact match required)
• Package / Case: 1808 (4520 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Voltage Rating: Equal to or greater than 1500V (1.5kV)
• Tolerance: Equal to or better than ±20%
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) preferred

Temperature Coefficient Consideration: The original part specifies C0G/NP0 temperature coefficient. Substitute parts with alternative temperature coefficients (such as X7R) may be considered functionally equivalent if all other electrical and mechanical parameters are met, provided the application does not require the specific stability characteristics of C0G/NP0.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical and mechanical requirements for direct replacement of the 1808SA101MAT3A:

C4520C0G3F101K200KA (TDK Corporation): This part provides a voltage rating of 3000V (3kV), exceeding the original 1500V specification by 100%. The tolerance is improved to ±10% compared to the original ±20%. The temperature coefficient remains C0G, maintaining identical thermal stability characteristics. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are matched. Dimensional variation in thickness (2.20mm vs. 1.45mm) must be evaluated for PCB layout constraints.

C1808C101KHRAC7800 (KEMET): This part also provides a voltage rating of 3000V (3kV) with improved tolerance of ±10%. The temperature coefficient is specified as X7R rather than C0G/NP0, which represents a different thermal stability profile. All compliance certifications are matched. Dimensional variation in thickness (1.75mm vs. 1.45mm) is less pronounced than the TDK alternative. The Low ESL feature is noted in the product specifications.

Both parts are Active status components with unlimited MSL ratings and full regulatory compliance. Selection between these substitutes should be based on specific application requirements regarding temperature coefficient stability and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can C4520C0G3F101K200KA or C1808C101KHRAC7800 be used as direct replacements for 1808SA101MAT3A?

A: Yes. Both substitute parts maintain the same capacitance value (100 pF), package form factor (1808 / 4520 Metric), mounting type (Surface Mount MLCC), and operating temperature range (-55°C ~ 125°C). Both exceed the original voltage rating (3000V vs. 1500V) and improve tolerance specifications (±10% vs. ±20%). All three parts are ROHS3 compliant with MSL Level 1 ratings.

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

A: C0G/NP0 and X7R are distinct temperature coefficient classifications. The original 1808SA101MAT3A and TDK substitute C4520C0G3F101K200KA both use C0G/NP0, which provides superior temperature stability with minimal capacitance variation across the operating range. The KEMET substitute C1808C101KHRAC7800 uses X7R, which has a different thermal response. Selection depends on whether the application requires the specific stability characteristics of C0G/NP0.

Q: Are there physical size differences between these parts?

A: Yes. All three parts use the 1808 (4520 Metric) package, but thickness specifications vary: the original is 0.057" (1.45mm), the TDK substitute is 0.087" (2.20mm), and the KEMET substitute is 0.069" (1.75mm). Length and width dimensions also show minor variations. PCB layout and component stacking requirements must be evaluated before selection.

Q: Do all three parts have the same compliance certifications?

A: Yes. The original 1808SA101MAT3A and both substitute parts (C4520C0G3F101K200KA and C1808C101KHRAC7800) are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. All three carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What is the advantage of the higher voltage rating in the substitute parts?

A: The substitute parts are rated at 3000V (3kV), double the original 1500V (1.5kV) specification. This provides additional safety margin and allows use in higher voltage applications. However, the higher voltage rating does not affect performance in circuits designed for 1500V operation.
