CL10B331KB8NNND Equivalent & Substitute Parts

Part Overview

The CL10B331KB8NNND is a 330 pF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0603 (1608 Metric) surface mount package. This multilayer ceramic capacitor (MLCC) with X7R temperature coefficient is classified as Active product status and is ROHS3 compliant. The part operates across -55°C to 125°C and features MSL 1 (Unlimited) moisture sensitivity rating, suitable for general purpose applications including bypass and decoupling circuits.

Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, temperature coefficient) and mechanical compatibility (package size, mounting type, physical dimensions). Alternative sources provide equivalent performance with identical or enhanced ratings.

Substitute Part Grouping Explanation

Substitute parts are classified into three categories based on electrical and mechanical compatibility with the main part CL10B331KB8NNND:

Parametric Equivalent: Parts with identical electrical specifications (330 pF, ±10%, 50V, X7R) and mechanical compatibility. These parts are direct functional replacements with no performance trade-offs.

Direct Manufacturer Equivalents: Parts from alternative manufacturers (KEMET, KYOCERA AVX) that match all critical electrical parameters and package specifications. These parts satisfy identical circuit requirements.

Upgrade Parts: Parts with enhanced specifications including higher voltage ratings (100V, 200V, 250V) or tighter tolerance (±5%) while maintaining the same capacitance value, package size, and temperature coefficient. These parts provide superior performance margins and are backward compatible in applications where the original 50V rating is not a limiting constraint.

Substitution is determined by the following key parameters:

Capacitance value (330 pF)
Temperature coefficient (X7R)
Package size (0603 / 1608 Metric)
Mounting type (Surface Mount, MLCC)
Operating temperature range (-55°C to 125°C)
RoHS and REACH compliance status

Frequently Asked Questions (FAQ)

Q: Can CL10B331KB8NNNC be used as a direct replacement for CL10B331KB8NNND?

A: Yes. CL10B331KB8NNNC is a parametric equivalent with identical electrical specifications (330 pF ±10% 50V X7R) and mechanical compatibility (0603 package, surface mount MLCC). The only difference is packaging format. Both parts are Active status with ROHS3 compliance.

Q: What is the difference between the Samsung and KEMET versions?

A: Both CL10B331KB8NNND (Samsung) and C0603C331K5RAC7867 (KEMET) meet identical electrical requirements: 330 pF ±10% 50V X7R in 0603 package. Physical thickness differs marginally (0.035" vs. 0.034"), which is within standard PCB assembly tolerances. KEMET part offers higher inventory availability.

Q: Can I use a 100V rated part instead of the 50V original?

A: Yes. Parts such as C0603C331K1RAC7867 (100V) or KGM15AR72A331JT (100V) are backward compatible. Higher voltage rating provides additional safety margin in the circuit. All other specifications (330 pF, ±10%, X7R, 0603 package) remain identical. This substitution is valid when circuit design permits higher voltage components.

Q: What does ±5% tolerance mean compared to ±10%?

A: ±5% tolerance (C0603C331J5RAC7867, KGM15AR71H331JT, KGM15AR72A331JT) provides tighter capacitance accuracy than ±10%. For a 330 pF part, ±5% tolerance allows 313.5 pF to 346.5 pF variation, while ±10% allows 297 pF to 363 pF. Use ±5% parts in applications requiring precise capacitance values.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original CL10B331KB8NNND specifications.

Q: Why are some parts marked "Not For New Designs"?

A: GRM188R72A331KA01D and GRM188R72E331KW07D carry this designation due to manufacturer lifecycle decisions. While electrically and mechanically compatible, these parts should not be selected for new circuit designs. Use Active status alternatives instead.

Q: Does package format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Package format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical. CL10B331KB8NNNC (Cut Tape & Digi-Reel) and CL10B331KB8NNND (standard packaging) are functionally equivalent.

Q: Can I mix different manufacturers in the same circuit?

A: Yes. All substitute parts meet identical electrical specifications and mechanical compatibility. Mixing Samsung, KEMET, KYOCERA AVX, and Murata parts in the same circuit is acceptable from an engineering standpoint. Verify procurement and supply chain requirements with your organization.

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

A: MSL 1 indicates the lowest moisture sensitivity level. These parts require no special moisture control during storage or handling, simplifying logistics and assembly processes compared to higher MSL ratings.
