Key Parameters

Substitute Part Grouping Explanation

Substitution of the C1005X5R1H331M050BA is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 330 pF
• Voltage Rating: 50V minimum
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)

Allowable Variations:

• Temperature Coefficient: X5R or C0G/NP0 (both acceptable for general purpose applications)
• Tolerance: ±1%, ±2%, ±5%, ±10%, or ±20% (tighter tolerances are acceptable substitutes)
• Operating Temperature Range: -55°C ~ 85°C (X5R) or -55°C ~ 125°C (C0G/NP0)

Substitute parts are grouped by temperature coefficient type and tolerance specification. Parts with C0G/NP0 temperature coefficient offer superior stability and wider operating temperature range compared to the original X5R specification, making them suitable upgrades for applications requiring enhanced performance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Temperature Coefficient):

The KGM05AR51H331KH from KYOCERA AVX provides direct X5R substitution with active product status and ROHS3 compliance. This part maintains identical temperature coefficient and operating temperature range characteristics while offering current manufacturing availability.

For Enhanced Performance (Upgraded Temperature Coefficient):

KEMET C0402C331J5GAC7867 and C0402C331K5GAC7867 are active production alternatives with C0G/NP0 temperature coefficient, providing superior temperature stability and extended operating range (-55°C ~ 125°C). These parts are ROHS3 compliant and available in high volume. The ±5% tolerance variant (C0402C331J5GAC7867) matches the tolerance class of common X5R applications while the ±10% variant (C0402C331K5GAC7867) provides cost optimization.

TDK Corporation C1005C0G1H331J050BA offers C0G/NP0 performance with ±5% tolerance in 0402 package, though marked as not for new designs. KEMET C0402C331G5GAC7867 provides ±2% tolerance for applications requiring tighter capacitance control.

Compliance Considerations:

All substitute parts listed maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level remains at MSL 1 (unlimited) across all alternatives, ensuring consistent handling requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a C0G/NP0 temperature coefficient part as a substitute for the X5R original?

A: Yes. C0G/NP0 parts with matching 330 pF capacitance, 50V voltage rating, and 0402 package are electrically compatible. C0G/NP0 offers superior temperature stability and wider operating range (-55°C ~ 125°C versus -55°C ~ 85°C for X5R), making it suitable for applications where the original X5R specification is not a critical design requirement.

Q: What tolerance variations are acceptable?

A: The original part specifies ±20% tolerance. Substitute parts with ±1%, ±2%, ±5%, or ±10% tolerance are acceptable as these represent tighter tolerance classes. Selection depends on circuit requirements for capacitance accuracy. Applications tolerant of ±20% variation can use any listed substitute; applications requiring tighter control should select parts with ±5% or better tolerance.

Q: Are all substitute parts available in the same packaging format?

A: All listed substitutes are 0402 (1005 Metric) surface mount packages with identical physical dimensions (0.039" L x 0.020" W). Packaging format (Tape & Reel or Cut Tape) varies by manufacturer and distributor but does not affect electrical or mechanical compatibility.

Q: Which substitute offers the best current availability?

A: KEMET C0402C331J5GAC7867 shows the highest inventory level (227,580 pcs) with active product status. This part combines C0G/NP0 performance, ±5% tolerance, 50V rating, and 0402 package in a currently manufactured component.

Q: Can I substitute the C0402C331JAGAC7867 (250V rated) for the 50V original?

A: The C0402C331JAGAC7867 is rated for 250V operation, which exceeds the 50V requirement. While electrically compatible for 50V circuits, this part has increased thickness (0.024" versus 0.022" maximum), which may affect PCB assembly clearances. Use only if mechanical space permits the additional thickness.
