08055C151KAT4A Equivalent & Substitute Parts

Part Overview

The 08055C151KAT4A is a 150 pF ±10% 50V ceramic capacitor manufactured by KYOCERA AVX in 0805 (2012 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) with X7R temperature coefficient 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 and carries MSL 1 (Unlimited) moisture sensitivity rating. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, obsolescence, or when design requirements permit higher voltage ratings or alternative packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 08055C151KAT4A is determined by the following critical parameters: capacitance value (150 pF), tolerance (±10%), temperature coefficient (X7R), package format (0805/2012 Metric), and surface mount mounting type. The rated voltage may be equal or higher without affecting circuit compatibility, as a higher voltage rating provides additional safety margin. All substitute parts must maintain the same capacitance, tolerance, temperature coefficient, and physical package dimensions to ensure direct PCB compatibility and electrical performance equivalence.

Substitute parts are organized into three categories:

Upgrade Equivalent: Parts with identical capacitance and package but higher voltage rating (100V vs. 50V), suitable for designs requiring increased voltage headroom.

Parametric Equivalent: Parts from the same manufacturer with identical electrical and mechanical specifications, differing only in packaging format or inventory source.

Direct Equivalents: Parts from alternative manufacturers (KEMET, YAGEO, Samsung Electro-Mechanics) meeting all electrical and mechanical specifications with identical 0805 package format.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 08055C151KAT2A (KYOCERA AVX) is the recommended parametric equivalent, offering identical electrical specifications to the 08055C151KAT4A with significantly higher inventory availability (30282 Pcs vs. 602 Pcs). Both parts are Active status and ROHS3 compliant.

Upgrade Option: 08051C151KAT2A (KYOCERA AVX) provides a 100V rated alternative from the same manufacturer, suitable for applications where increased voltage margin is beneficial. This part maintains all other specifications and carries Active product status.

Cross-Manufacturer Alternatives: C0805C151K5RAC7800 (KEMET) and CC0805KRX7R9BB151 (YAGEO) are direct electrical and mechanical equivalents with Active product status and ROHS3 compliance. Both are suitable for direct substitution in designs where multi-source qualification is required.

Avoid: CL21B151KBANNNC (Samsung Electro-Mechanics) carries Obsolete product status and should not be selected for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute 08055C151KAT4A with 08051C151KAT2A? A: Yes. The 08051C151KAT2A is a direct upgrade equivalent with identical capacitance (150 pF), tolerance (±10%), temperature coefficient (X7R), and 0805 package. The higher voltage rating (100V vs. 50V) provides additional design margin and does not affect compatibility in circuits rated for 50V operation.

Q: Are KEMET and YAGEO parts electrically equivalent to KYOCERA AVX? A: Yes. C0805C151K5RAC7800 (KEMET) and CC0805KRX7R9BB151 (YAGEO) meet all electrical specifications: 150 pF capacitance, ±10% tolerance, 50V rating, X7R temperature coefficient, and 0805 package format. All three manufacturers' parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between 08055C151KAT4A and 08055C151KAT2A? A: Both parts are manufactured by KYOCERA AVX with identical electrical and mechanical specifications. The difference lies in packaging format or internal manufacturing revision. Both are suitable for direct substitution.

Q: Why is CL21B151KBANNNC listed as Obsolete? A: CL21B151KBANNNC carries Obsolete product status from Samsung Electro-Mechanics. While current inventory exists, this part should not be selected for new designs due to discontinued manufacturer support and potential future supply unavailability.

Q: Can these parts be used interchangeably on the same PCB? A: Yes, all Active status parts listed are mechanically and electrically interchangeable. All share the 0805 (2012 Metric) package format with identical footprint dimensions (0.079" L x 0.049" W). Physical thickness variations (0.028" to 0.037") are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: What compliance certifications apply to all substitute parts? A: All Active status parts are ROHS3 compliant, REACH Unaffected, and carry ECCN EAR99 classification. All maintain MSL 1 (Unlimited) moisture sensitivity rating, requiring no special storage or handling precautions.
