Equivalent & Substitute Parts for 08055C101MAT2A

Part Overview

The 08055C101MAT2A is a 100 pF ±20% 50V X7R ceramic capacitor in 0805 (2012 Metric) surface mount package manufactured by KYOCERA AVX. This multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant, REACH unaffected, and carries MSL 1 (unlimited moisture sensitivity level) rating. Substitute parts are identified to address applications requiring improved tolerance specifications, higher voltage ratings, or alternative temperature coefficient characteristics while maintaining the same physical package and core electrical parameters.

Substitute Part Grouping Explanation

Substitution eligibility is determined by three primary criteria: capacitance value (100 pF fixed), physical package (0805 / 2012 Metric fixed), and mounting type (surface mount MLCC fixed). Within these constraints, substitute parts are grouped by tolerance specification and voltage rating, which are the variable parameters that define application suitability.

The 08055C101MAT2A operates at 50V with ±20% tolerance. Substitute parts fall into the following categories:

Same Voltage (50V), Improved Tolerance: Parts with tighter tolerance specifications (±5% or ±10%) at the same 50V rating provide enhanced capacitance accuracy for circuits requiring stricter component specifications.

Higher Voltage Rating (100V or 200V), Same or Improved Tolerance: Parts rated for 100V or 200V maintain the same 100 pF capacitance and 0805 package while providing voltage derating margin for applications operating below their rated voltage.

Alternative Temperature Coefficient (C0G/NP0): Parts with C0G/NP0 temperature coefficient replace X7R variants when applications require superior temperature stability and lower capacitance drift across the operating range, though at higher voltage ratings (50V, 100V, or 630V).

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating consistent with the original 08055C101MAT2A. Selection between X7R and C0G/NP0 temperature coefficients depends on application requirements: X7R variants provide stable capacitance across the full -55°C to 125°C range with moderate temperature drift, while C0G/NP0 variants deliver superior temperature stability with minimal capacitance variation but are available at higher voltage ratings.

For applications operating at or below 50V with standard tolerance requirements, 08055C101KAT2A (±10% X7R) or 08055C101JAT2A (±5% X7R) provide direct substitution with improved tolerance specifications. For circuits requiring voltage derating margin or operating in higher voltage environments, 08051C101KAT2A (100V X7R) or 08052C101KAT2A (200V X7R) are suitable while maintaining the same capacitance and package footprint.

For precision applications demanding tight capacitance tolerance and superior temperature stability, KGM21BCG1H101FT (±1% C0G/NP0 at 50V) or KGM21BCG2A101FT (±1% C0G/NP0 at 100V) are appropriate selections. The 0805CA101KAT1A (630V C0G/NP0) addresses high-voltage applications where extreme voltage derating is required.

Frequently Asked Questions (FAQ)

Q: Can I substitute 08055C101MAT2A with a higher voltage-rated part?

A: Yes. Parts rated for 100V or 200V are direct substitutes for 50V applications. Higher voltage ratings provide derating margin and do not affect circuit operation when the applied voltage remains below the original 50V specification. Physical package dimensions and mounting characteristics remain identical.

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

A: X7R capacitors exhibit capacitance variation of ±15% across the -55°C to 125°C operating range, suitable for general-purpose applications. C0G/NP0 capacitors maintain capacitance within ±30 ppm/°C, delivering superior temperature stability for precision circuits. C0G/NP0 variants in this product line are available at 50V, 100V, and 630V ratings.

Q: Are tolerance specifications interchangeable?

A: Tolerance specifications define the acceptable capacitance deviation from the nominal 100 pF value. The original ±20% tolerance allows capacitance between 80 pF and 120 pF. Tighter tolerances (±10%, ±5%, ±1%) restrict the acceptable range and are suitable for circuits requiring precise capacitance values. Substituting a tighter tolerance part into a circuit designed for ±20% tolerance introduces no compatibility issues.

Q: Will substitute parts fit the same PCB footprint?

A: All listed substitute parts use the 0805 (2012 Metric) package with identical mounting pad layout. Physical dimensions are 2.01 mm length × 1.25 mm width × 0.94 mm thickness (with minor variations in length of ±0.09 mm across the product line). All parts are surface mount MLCCs with identical soldering characteristics and PCB footprint compatibility.

Q: What inventory status should I consider for procurement?

A: All substitute parts listed are active products with new original stock available. Inventory quantities range from 1,627 to 66,623 pieces, indicating consistent availability across the product line.
