Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0201B151K500CT ceramic capacitor is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 150 pF
• Tolerance: ±10%
• Voltage rating: 50V
• Temperature coefficient: X7R

Physical Parameters:

• Package type: 0201 (0603 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Maximum thickness: 0.013" (0.33mm)

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1

All substitute parts listed maintain identical electrical specifications and physical dimensions, ensuring direct functional and mechanical compatibility. Variations in product status, manufacturer ratings, and packaging format (Tape & Reel versus Cut Tape) do not affect electrical performance or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The CGA1A2X7R1H151K030BA (TDK Corporation), CC0201KRX7R9BB151 (YAGEO), and KGM03AR71H151KH (KYOCERA AVX) are direct electrical and mechanical equivalents to the 0201B151K500CT. All three maintain Active product status, ensuring long-term availability and supply chain stability. The CGA1A2X7R1H151K030BA carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade components. All primary substitutes are supplied in Tape & Reel packaging format, consistent with the original part.

Secondary Substitute (Obsolete Status):

The C0603X7R1H151K (TDK Corporation) is electrically and mechanically equivalent but carries Obsolete product status. This part is available in limited inventory (735 pcs) and is supplied in Cut Tape and Digi-Reel® packaging format rather than standard Tape & Reel. Selection of this part should be limited to applications where existing inventory must be consumed or where alternative packaging formats are acceptable.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 classification, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CGA1A2X7R1H151K030BA be used as a direct replacement for 0201B151K500CT?

A: Yes. The CGA1A2X7R1H151K030BA is electrically and mechanically identical to the 0201B151K500CT. Both components share identical capacitance (150 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (0201/0603 Metric), and physical dimensions. The CGA1A2X7R1H151K030BA additionally carries AEC-Q200 automotive qualification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape and Digi-Reel® packaging supplies components on shorter tape segments or alternative reel formats. Both packaging formats contain identical components; the difference is in supply format and handling during assembly operations.

Q: Why is C0603X7R1H151K marked as Obsolete?

A: Obsolete product status indicates that the manufacturer has discontinued active production and support for this part number. While limited inventory may remain available, long-term supply cannot be guaranteed. Active alternatives such as CGA1A2X7R1H151K030BA, CC0201KRX7R9BB151, or KGM03AR71H151KH are recommended for new designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (CGA1A2X7R1H151K030BA, C0603X7R1H151K, CC0201KRX7R9BB151, and KGM03AR71H151KH) are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original 0201B151K500CT.

Q: Can these capacitors be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), maximum thickness (0.013" / 0.33mm), and surface mount mounting type. They are mechanically and electrically interchangeable on PCB assemblies designed for 0201 (0603 Metric) ceramic capacitors.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control requirements. Components with MSL 1 do not require desiccant packaging or controlled storage environments, simplifying inventory management and reducing handling costs.

Q: Which substitute offers the best long-term availability?

A: CGA1A2X7R1H151K030BA (TDK Corporation) and KGM03AR71H151KH (KYOCERA AVX) both carry Active product status with substantial inventory levels (42,955 pcs and 42,498 pcs respectively), indicating strong manufacturer commitment to continued production and supply.
