Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C0402X7R0J331M020BC is determined by the following critical parameters:

• Capacitance Value: Must be 330 pF
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 01005 (0402 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.40mm x 0.20mm footprint and 0.22mm maximum thickness
• Operating Temperature Range: Must support -55°C ~ 125°C
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

Voltage rating may be equal to or greater than the original 6.3V specification, as higher-rated components are electrically compatible in lower-voltage applications. Tolerance variations (±20% or ±10%) are acceptable provided the application permits the specified tolerance range.

Parameter Comparison

Engineering Selection Recommendations

LMK042B7331MC-W (Taiyo Yuden) is a direct functional equivalent with identical capacitance, tolerance, temperature coefficient, and package specifications. The 10V voltage rating provides margin above the original 6.3V specification. However, this part carries a "Not For New Designs" status, limiting its suitability for new product development. Existing inventory of 41,001 units supports legacy system maintenance and repair applications.

CL02B331KP2NNNC (Samsung Electro-Mechanics) is the preferred substitute for new designs. This part maintains all critical electrical and mechanical parameters while offering an improved ±10% tolerance compared to the original ±20% specification. The 10V voltage rating exceeds the original requirement. Active product status and ROHS3 compliance ensure long-term availability and regulatory alignment. Current inventory of 993 units supports immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can LMK042B7331MC-W and CL02B331KP2NNNC be used interchangeably with C0402X7R0J331M020BC?

A: Both parts are electrically and mechanically compatible substitutes. They share identical capacitance (330 pF), temperature coefficient (X7R), package (01005), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (10V vs. 6.3V) are compatible with applications designed for the original part.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the acceptable capacitance variation from the nominal value. The original part permits ±20% deviation (264 pF to 396 pF), while CL02B331KP2NNNC permits ±10% deviation (297 pF to 363 pF). Applications requiring tighter capacitance control benefit from the improved tolerance of the Samsung part.

Q: Why is LMK042B7331MC-W marked "Not For New Designs"?

A: This designation indicates the manufacturer is phasing out the product line. While suitable for legacy system support and repair, new product development should prioritize CL02B331KP2NNNC, which carries Active status and ensures long-term supply continuity.

Q: Are there any compliance or regulatory differences between these parts?

A: CL02B331KP2NNNC and LMK042B7331MC-W are both ROHS3 compliant. The original C0402X7R0J331M020BC is REACH unaffected. All three parts carry ECCN EAR99 classification and HTSUS code 8532.24.0020.

Q: Can these parts be used in SMPS filtering applications?

A: LMK042B7331MC-W is specified for SMPS filtering applications. CL02B331KP2NNNC and the original part are specified for general purpose applications. Application-specific performance validation is required for SMPS environments.
