Substitute Part Grouping Explanation

Substitution eligibility for the CL31B155KBHVPNE is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Capacitance value: 1.5 µF (exact match)
• Tolerance: ±10% (exact match)
• Voltage rating: 50V (exact match or higher)
• Temperature coefficient: X7R (exact match)
• Operating temperature range: -55°C to 125°C (exact match or wider)

Mechanical Equivalence Requirements:

• Package format: 1206 (3216 Metric) (exact match)
• Mounting type: Surface Mount, MLCC (exact match)
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) (exact match)
• Maximum thickness: 0.071" (1.80mm) (exact match or less)

Compliance & Certification Requirements:

• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for environmental standards)
• MSL rating: 1 (Unlimited) (exact match)
• REACH status: REACH Unaffected (exact match)

The substitute part C1206C155K5RACAUTO meets all specified criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

The MSL 1 (Unlimited) rating on both parts indicates no moisture sensitivity restrictions during handling and storage.

The C1206C155K5RACAUTO is available in Tape & Reel packaging with 6493 pieces in inventory, compared to 820 pieces for the CL31B155KBHVPNE. Component selection between these two parts depends on procurement availability, lead time requirements, and packaging format preferences for assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the C1206C155K5RACAUTO replace the CL31B155KBHVPNE in automotive circuits?

A: Yes. Both parts are AEC-Q200 qualified and share identical electrical specifications (1.5 µF, ±10%, 50V, X7R), operating temperature range (-55°C to 125°C), and mechanical dimensions (1206 package). Direct substitution is supported for automotive applications.

Q: Are there differences in packaging between these two parts?

A: The CL31B155KBHVPNE is supplied in standard packaging format, while the C1206C155K5RACAUTO is supplied in Tape & Reel (TR) format. Both are Surface Mount MLCCs with identical physical dimensions and mounting characteristics. Packaging format selection depends on assembly line requirements and volume handling procedures.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both the CL31B155KBHVPNE and C1206C155K5RACAUTO are ROHS3 compliant and REACH Unaffected. Both carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions.

Q: What is the significance of the X7R temperature coefficient?

A: X7R designates a temperature coefficient class that maintains capacitance stability across the -55°C to 125°C operating range with minimal variation. Both parts meet this specification, ensuring consistent performance across automotive temperature extremes.

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

A: Yes. The identical 1206 (3216 Metric) package dimensions, Surface Mount mounting type, and electrical specifications enable direct PCB footprint compatibility. No circuit design modifications are required for substitution.

Q: What inventory considerations apply to these parts?

A: The CL31B155KBHVPNE has 820 pieces in stock, while the C1206C155K5RACAUTO has 6493 pieces available. Procurement decisions should account for lead time requirements and volume availability from each manufacturer.
