08051C151KAT2A Equivalent & Substitute Parts

Part Overview

The 08051C151KAT2A is a 150 pF ±10% 100V ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient in 0805 (2012 Metric) surface mount package. This part is Active status and widely used in general purpose applications. Substitute parts are identified based on matching capacitance, voltage rating, package dimensions, and compliance certifications. Alternative models may be required due to inventory availability, specific tolerance requirements, or temperature coefficient performance needs in circuit design.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

Capacitance: 150 pF (exact match required)
Package / Case: 0805 (2012 Metric) (exact match required)
Voltage Rating: 100V or higher (equal or greater voltage acceptable)
Mounting Type: Surface Mount, MLCC (exact match required)
RoHS Status: ROHS3 Compliant (compliance requirement)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Consideration:

Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)
Tolerance: ±1%, ±2%, ±5%, or ±10% (tighter tolerances are acceptable substitutes)

Substitute parts are grouped into two categories: KYOCERA AVX KGM series (C0G/NP0 temperature coefficient) and KEMET C0805C series (C0G/NP0 temperature coefficient with Low ESL feature). TDK C2012C0G2W151J060AA is listed as manufacturer recommended with higher voltage rating (450V).

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage conditions. Selection between substitutes depends on application-specific tolerance and voltage requirements:

Direct Replacement (Same Tolerance & Voltage): KGM21BCG2A151KT and C0805C151K1GAC7800 provide direct functional equivalence with ±10% tolerance and 100V rating. Both are Active status products with full inventory availability.

Improved Tolerance Options: KGM21BCG2A151FT (±1%) and C0805C151F1GAC7800 (±1%) offer tighter tolerance performance for precision-critical circuits while maintaining 100V voltage rating and Active product status.

Higher Voltage Capability: C0805C151J2GAC7800 (200V), C0805C151JAGAC7800 (250V), C0805C151K2GAC7800 (200V), and C2012C0G2W151J060AA (450V) provide elevated voltage ratings for applications requiring overvoltage margin. C2012C0G2W151J060AA is manufacturer recommended with 450V rating and reduced thickness (0.030").

Temperature Coefficient Consideration: All KEMET and KYOCERA AVX substitute parts use C0G/NP0 temperature coefficient, which provides superior stability compared to the original X7R specification across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 08051C151KAT2A? A: Yes. Higher voltage ratings are acceptable substitutes. Parts rated 200V, 250V, or 450V will function in circuits designed for 100V operation. Voltage derating provides additional safety margin and reliability.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across -55°C to 125°C. C0G/NP0 provides ±30 ppm/°C (approximately ±0.3% across the same range). C0G/NP0 offers superior temperature stability for precision applications.

Q: Are KEMET C0805C series parts with Low ESL feature compatible with the original design? A: Yes. Low ESL (Equivalent Series Inductance) is a beneficial feature that reduces high-frequency impedance. This does not affect DC or low-frequency circuit operation and is fully compatible with designs using the original part.

Q: Can I substitute a ±1% tolerance part for the original ±10% part? A: Yes. Tighter tolerance is a direct upgrade. A ±1% part will meet all circuit requirements that accept ±10% tolerance, with improved capacitance accuracy.

Q: Is the thickness difference between 0.037" (0.94mm) and 0.035" (0.88mm) significant? A: No. Both thicknesses are within standard 0805 (2012 Metric) package specifications. The 0.002" difference does not affect PCB layout, assembly, or electrical performance.

Q: Are all substitute parts in Active product status? A: Yes. All listed substitute parts are Active status products with current manufacturing and full inventory availability.
