Key Parameters

Substitute Part Grouping Explanation

Substitution of ceramic capacitors is determined by strict equivalence across the following parameters: capacitance value, tolerance, rated voltage, temperature coefficient, package format, and mounting type. All substitute parts listed maintain identical capacitance (150 pF), tolerance (±10%), temperature coefficient (X7R), package (0805/2012 Metric), and mounting type (Surface Mount, MLCC). Substitutes are grouped into two categories:

Direct Equivalents (Same Voltage Rating - 50V): Parts with identical electrical specifications including 50V rated voltage. These provide one-to-one functional replacement without circuit redesign.

Upgraded Equivalents (Higher Voltage Rating - 100V): Parts with 100V rated voltage maintain all other electrical parameters while providing enhanced voltage margin. These are suitable for applications where increased voltage headroom is beneficial.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and -55°C to 125°C operating temperature range as specified for the primary part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (50V Rating): The KEMET C0805C151K5RAC7800 is the preferred direct equivalent, offering identical electrical specifications with significantly higher inventory availability (13,990 units) and active product status. This part is suitable for immediate procurement and integration into production environments.

For Voltage-Upgraded Applications: The KYOCERA AVX 08051C151KAT2A provides a 100V rated equivalent while maintaining all other electrical parameters. This upgrade is applicable when circuit design permits higher voltage margin or when component standardization across voltage-rated variants is required. This part is active in production with 765 units available.

Obsolete Part Consideration: The Samsung Electro-Mechanics CL21B151KBANNNC is marked as obsolete and should not be selected for new designs or long-term production planning, despite current inventory availability.

All recommended substitutes maintain full ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the 08051C151KAT2A (100V) be used in place of the 08055C151KAT9A (50V)? A: Yes. The 100V-rated part maintains identical capacitance (150 pF), tolerance (±10%), temperature coefficient (X7R), and package format (0805). Higher voltage rating does not affect circuit functionality in applications designed for 50V operation.

Q: What is the difference between the KYOCERA AVX and KEMET 150 pF 50V parts? A: Both parts are electrically identical with 150 pF capacitance, ±10% tolerance, 50V rating, and X7R temperature coefficient in 0805 package. The primary differences are manufacturer, packaging format (KYOCERA AVX uses standard packaging; KEMET uses Tape & Reel), and inventory availability.

Q: Why is the Samsung CL21B151KBANNNC marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued production. While current inventory exists, this part should not be specified for new designs or applications requiring long-term component availability.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 rating, meeting standard environmental and manufacturing requirements.

Q: Does package format affect substitution compatibility? A: No. All parts use the 0805 (2012 Metric) package format with identical physical dimensions and mounting characteristics. Packaging format (Tape & Reel, Cut Tape, or standard) refers to supply method only and does not affect component performance or PCB compatibility.
