CL31B274KBFNNNE Equivalent & Substitute Parts

Part Overview

The CL31B274KBFNNNE is a 0.27 µF ceramic capacitor manufactured by Samsung Electro-Mechanics, rated for 50V with X7R temperature coefficient in 1206 (3216 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) is designed for general-purpose applications and is currently in active production status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to supply constraints, inventory availability, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on the following criteria:

Direct Equivalents maintain all electrical and mechanical parameters identical to the main part:

• Capacitance: 0.27 µF (exact match)
• Voltage Rating: 50V (exact match)
• Tolerance: ±10% (exact match)
• Temperature Coefficient: X7R (exact match)
• Package: 1206 (3216 Metric) (exact match)
• Operating Temperature: -55°C ~ 125°C (exact match)

Upgraded Substitutes provide enhanced specifications while maintaining core compatibility:

• Tighter tolerance (±5% instead of ±10%) improves circuit precision
• Higher voltage rating (100V instead of 50V) provides additional safety margin
• All other parameters remain equivalent

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and surface mount MLCC mounting type. Physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) are consistent across all options.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Equivalent Performance):

Use 12065C274KAT2A (KYOCERA AVX) or C1206C274K5RAC7800 (KEMET) when direct electrical and mechanical equivalence is required. Both parts are in active production status, ROHS3 compliant, and maintain identical capacitance, voltage rating, tolerance, and temperature coefficient specifications. These parts are suitable for new designs and production applications.

For Enhanced Tolerance Requirements:

Use 12065C274JAT2A (KYOCERA AVX) when circuit design requires tighter capacitance tolerance (±5% instead of ±10%). This part maintains all other specifications and is in active production status.

For Higher Voltage Margin Applications:

Use C1206C274K1RAC7800 (KEMET) when design specifications allow or require 100V rating instead of 50V. This part provides additional voltage safety margin while maintaining all other electrical parameters and is in active production status.

Not Recommended for New Designs:

GRM319R71H274KA01D (Murata Electronics) carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where original part compatibility is mandatory.

Frequently Asked Questions (FAQ)

Q: Can I use a 100V rated capacitor in place of a 50V rated capacitor?

A: Yes. C1206C274K1RAC7800 (100V rating) is electrically compatible with CL31B274KBFNNNE (50V rating) in applications designed for 50V operation. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance at lower operating voltages.

Q: What is the difference between ±10% and ±5% tolerance?

A: Tolerance specifies the allowable deviation from the nominal capacitance value. ±10% tolerance allows deviation from 0.243 µF to 0.297 µF, while ±5% tolerance allows deviation from 0.257 µF to 0.283 µF. Tighter tolerance (±5%) is suitable for precision circuits requiring more accurate capacitance values.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm) dimensions. Thickness variations (0.037" to 0.055") do not affect PCB footprint compatibility but may impact board-level clearance in space-constrained designs.

Q: What does "Not For New Designs" mean for GRM319R71H274KA01D?

A: This designation indicates the part is in mature or end-of-life status. While functionally equivalent and currently in stock, it is not recommended for new product development. Use this part only for replacement or repair of existing systems using this specific component.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the main part CL31B274KBFNNNE and all substitutes, are ROHS3 compliant and suitable for applications requiring regulatory compliance with hazardous substance restrictions.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life under normal storage conditions and do not require special moisture-controlled packaging or baking procedures prior to soldering.
