ECJ-2VB2D332K Equivalent & Substitute Parts

Part Overview

The ECJ-2VB2D332K is a 3300 pF ceramic capacitor rated at 200V with X7R temperature coefficient in 0805 (2012 Metric) surface mount package, manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The capacitor is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Direct substitutes maintain identical electrical specifications, while upgrade options provide enhanced voltage ratings, improved tolerance, or alternative temperature coefficients for applications requiring higher performance margins.

Substitute Part Grouping Explanation

Substitution for ECJ-2VB2D332K is determined by strict equivalence in the following parameters:

Capacitance: 3300 pF (exact match required)
Voltage Rating: 200V minimum (equal or higher acceptable)
Temperature Coefficient: X7R (maintains capacitance stability across operating range)
Package: 0805 (2012 Metric) surface mount
Tolerance: ±10% or tighter (±5% acceptable as upgrade)
Operating Temperature: -55°C to 125°C (minimum requirement)
Mounting: Surface Mount, MLCC

Direct substitutes maintain all specifications at 200V with ±10% tolerance. Upgrade options provide higher voltage ratings (250V, 500V, 630V), improved tolerance (±5%), or alternative temperature coefficients (C0G/NP0) while preserving the 3300 pF capacitance and 0805 package form factor.

Engineering Selection Recommendations

Direct Substitutes (200V, ±10%, X7R): C0805C332K2RAC7800 (KEMET), CC0805KRX7RABB332 (YAGEO), and KGM21AR72D332KU (KYOCERA AVX) provide electrical equivalence to ECJ-2VB2D332K. All three are active products with ROHS3 compliance. KEMET C0805C332K2RAC7800 offers the smallest thickness profile (0.88mm) for space-constrained layouts. YAGEO and KYOCERA AVX options provide higher inventory availability.

Tolerance Upgrade (200V, ±5%, X7R): C0805C332J2RAC7800 (KEMET) maintains 200V rating with improved ±5% tolerance, suitable for applications requiring tighter capacitance control without voltage derating.

Voltage Upgrades (250V, X7R): C0805C332KARAC7800 (KEMET) provides 250V rating with ±10% tolerance. C0805C332JARAC7800 (KEMET) offers 250V with improved ±5% tolerance. Both maintain X7R temperature coefficient and 0805 package.

Temperature Coefficient Alternative (250V, C0G/NP0): C0805C332JAGAC7800 (KEMET) provides 250V rating with C0G/NP0 temperature coefficient and ±5% tolerance. C0G/NP0 offers superior capacitance stability across temperature compared to X7R, suitable for precision applications.

Frequently Asked Questions (FAQ)

Q: Can C0805C332K2RAC7800 directly replace ECJ-2VB2D332K? A: Yes. C0805C332K2RAC7800 matches all critical parameters: 3300 pF capacitance, ±10% tolerance, 200V rating, X7R temperature coefficient, and 0805 package. It is an active product with ROHS3 compliance.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R maintains capacitance within ±15% across -55°C to 125°C operating range. C0G/NP0 maintains capacitance within ±30 ppm/°C, providing superior stability for precision applications. C0G/NP0 is suitable when tighter capacitance tolerance across temperature is required.

Q: Can I use a 250V or 500V rated capacitor in place of the 200V original? A: Yes. Higher voltage ratings are acceptable substitutes. A 250V, 500V, or 630V rated capacitor will function in a 200V application. However, physical dimensions may differ; verify thickness and footprint compatibility with your PCB layout before substitution.

Q: What is the significance of the thickness difference between KEMET and YAGEO/KYOCERA AVX options? A: KEMET C0805C332K2RAC7800 has 0.88mm maximum thickness, while YAGEO CC0805KRX7RABB332 and KYOCERA AVX KGM21AR72D332KU have 1.45mm maximum thickness. Verify PCB clearance and component stacking height requirements before selecting. Thinner options are preferred for space-constrained designs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All active substitute and upgrade options listed are ROHS3 compliant. The original ECJ-2VB2D332K (obsolete) does not specify RoHS status.

Q: What does MSL 1 (Unlimited) mean? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry this rating.

Q: Which substitute offers the best balance of availability and performance? A: KYOCERA AVX KGM21AR72D332KU provides the highest inventory (22,635 pcs) with full electrical equivalence. KEMET C0805C332K2RAC7800 offers the smallest form factor (0.88mm thickness) with 1,736 pcs available. Selection depends on priority: availability, space constraints, or specific application requirements.
