C1005X8R2A331M050BA Equivalent & Substitute Parts

Part Overview

The C1005X8R2A331M050BA is a 330 pF ceramic capacitor manufactured by TDK Corporation in 0402 (1005 Metric) surface mount package. This component features X8R temperature coefficient, 100V rated voltage, and ±20% capacitance tolerance. The part is classified as "Not For New Designs," indicating it has been superseded in TDK's product portfolio. Finding equivalent or substitute parts is necessary for ongoing production support, legacy system maintenance, and design flexibility when the original part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C1005X8R2A331M050BA is determined by the following critical parameters: capacitance value (330 pF), rated voltage (100V), package type (0402), mounting method (Surface Mount MLCC), and compliance certifications (ROHS3, MSL 1). Temperature coefficient and tolerance are secondary parameters that may vary within acceptable ranges depending on application requirements.

The substitute parts identified maintain the primary electrical specifications (capacitance, voltage, package) and environmental compliance. Variations in tolerance and temperature coefficient represent trade-offs between cost, availability, and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

C1005NP02A331J050BA (TDK Corporation): This part offers the tightest tolerance specification (±5%) with C0G/NP0 temperature coefficient, providing superior stability across temperature extremes. Product status is Active, ensuring long-term availability. Select this substitute when tolerance precision and temperature stability are critical design requirements.

C1005X8R2A331K050BA (TDK Corporation): This part maintains X8R temperature coefficient matching the original specification with improved tolerance (±10% versus ±20%). Product status is "Not For New Designs," but inventory availability is significantly higher (10,442 pcs). Packaging is Cut Tape (CT) rather than Tape & Reel (TR). Select this substitute for cost-sensitive applications where tolerance relaxation from ±20% to ±10% is acceptable.

VJ0402H331KXBAC (Vishay Vitramon): This part provides X8R temperature coefficient with ±10% tolerance and Active product status. Manufactured by Vishay Vitramon, it represents a cross-manufacturer alternative with established long-term availability. Physical thickness is 0.024" (0.60mm) compared to 0.022" (0.55mm) for TDK parts. Select this substitute when multi-source qualification is required or when Vishay components are preferred in the supply chain.

Frequently Asked Questions (FAQ)

Q: Can C1005NP02A331J050BA replace C1005X8R2A331M050BA directly?

A: Yes, with design consideration. Both parts share identical capacitance (330 pF), voltage rating (100V), package (0402), and operating temperature range (-55°C ~ 150°C). The C1005NP02A331J050BA features C0G/NP0 temperature coefficient instead of X8R, providing superior temperature stability. Tolerance improves from ±20% to ±5%. This substitution is suitable when temperature coefficient stability is beneficial or required.

Q: What is the difference between X8R and C0G/NP0 temperature coefficients?

A: X8R temperature coefficient allows ±15% capacitance change over the operating temperature range. C0G/NP0 temperature coefficient allows ±30 ppm/°C, resulting in minimal capacitance variation across temperature. C0G/NP0 is preferred for precision applications; X8R is acceptable for general-purpose filtering and coupling applications.

Q: Is the thickness difference between TDK and Vishay parts significant?

A: The VJ0402H331KXBAC has maximum thickness of 0.024" (0.60mm) compared to 0.022" (0.55mm) for TDK parts. This 0.002" difference is within typical PCB assembly tolerances and should not cause placement or clearance issues in standard 0402 footprints. Verify clearance in designs with height-constrained applications.

Q: Why does C1005X8R2A331K050BA show higher inventory despite "Not For New Designs" status?

A: Inventory levels reflect current stock availability and do not indicate product lifecycle status. Higher inventory (10,442 pcs) may result from prior production runs or distributor stock levels. "Not For New Designs" status indicates TDK has superseded this part in their active portfolio, but existing stock remains available for legacy support.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging provides components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on cut segments of carrier tape, suitable for lower-volume or manual assembly. Both formats are compatible with standard pick-and-place equipment; CT may require manual feeding or special handling in some assembly environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed (C1005X8R2A331M050BA, C1005NP02A331J050BA, C1005X8R2A331K050BA, and VJ0402H331KXBAC) are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). All parts meet the same environmental and compliance requirements.
