ECJ-2VB2A471K Equivalent & Substitute Parts

Part Overview

The ECJ-2VB2A471K is a 470 pF ±10% 100V ceramic capacitor with X7R temperature coefficient in 0805 (2012 Metric) surface mount package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain identical electrical specifications (470 pF capacitance, 100V rated voltage, X7R temperature coefficient) and mechanical compatibility (0805 package, surface mount MLCC mounting type) to ensure direct functional replacement without circuit redesign.

Primary Substitution Criteria (Must Match Exactly):

Capacitance: 470 pF
Tolerance: ±10%
Voltage - Rated: 100V
Temperature Coefficient: X7R
Package / Case: 0805 (2012 Metric)
Mounting Type: Surface Mount, MLCC
Operating Temperature Range: -55°C ~ 125°C
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

Physical dimensions must remain within 0805 specification envelope
Thickness variations within the 0805 standard are acceptable
RoHS compliance status and REACH classification do not affect electrical substitutability but may impact procurement and regulatory requirements

Parts are grouped into two categories: direct substitutes (matching all primary criteria) and upgrade options (enhanced specifications with compatible package and mounting).

Engineering Selection Recommendations

Direct Substitutes (Recommended Priority Order):

C0805C471K1RAC7800 (KEMET) — Active product status with ROHS3 compliance and REACH unaffected classification. Highest inventory availability (72,510 pcs). Suitable for new designs and production environments with RoHS requirements.
CC0805KRX7R0BB471 (YAGEO) — Active product with ROHS3 compliance and REACH unaffected status. Thinnest profile (0.028" / 0.70mm) within 0805 specification. Inventory: 41,538 pcs. Optimal for space-constrained applications.
KGM21NR72A471KT (KYOCERA AVX) — Active product with ROHS3 compliance and REACH unaffected status. Largest inventory (185,065 pcs). Highest availability for volume production. Thickness 0.039" (1.00mm) remains within 0805 envelope.
VJ0805Y471KXBCW1BC (Vishay Vitramon) — Active product with ROHS3 compliance. Inventory: 4,539 pcs. Suitable for applications requiring Vishay component qualification.
VJ0805Y471KXBPW1BC (Vishay Vitramon) — Active product with ROHS3 compliance. Inventory: 696 pcs. Limited availability; use when Vishay specification is mandatory.

Alternative Substitutes (Non-Compliant RoHS):

08051C471KA12A (KYOCERA AVX) — Active product, RoHS non-compliant. Inventory: 1,145 pcs. Acceptable only for applications without RoHS regulatory requirements.
08051C471KAJ2A (KYOCERA AVX) — Active product, RoHS non-compliant. Inventory: 695 pcs. Acceptable only for applications without RoHS regulatory requirements.

Upgrade Option (Enhanced Temperature Range):

Use only when higher temperature stability and tighter tolerance are circuit requirements. Not a direct substitute due to different temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different temperature coefficient?

A: No. The ECJ-2VB2A471K specifies X7R temperature coefficient. Substitutes must maintain X7R classification. The Knowles Novacap 0805D471J101KHT uses C0G/NP0 coefficient and is an upgrade option only when circuit design explicitly requires superior temperature stability and tighter tolerance.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a manufacturing and regulatory classification that does not alter electrical specifications. ROHS3 compliant parts (KEMET, YAGEO, KYOCERA AVX KGM series, Vishay) are preferred for new designs and regulated markets. RoHS non-compliant parts (KYOCERA AVX 08051C series) function identically but may not meet procurement or end-product regulatory requirements.

Q: Are thickness variations within the 0805 package acceptable?

A: Yes. All substitute parts listed maintain 0805 (2012 Metric) package classification. Thickness variations (0.028" to 0.039") remain within the 0805 specification envelope and do not affect PCB assembly, soldering, or electrical performance. Verify PCB design clearances if space constraints exist.

Q: What is the difference between the KYOCERA AVX 08051C and KGM series?

A: Both are 470 pF ±10% 100V X7R 0805 capacitors from KYOCERA AVX. The 08051C series (08051C471KA12A, 08051C471KAJ2A) is RoHS non-compliant with lower inventory. The KGM21NR72A471KT is ROHS3 compliant with significantly higher inventory (185,065 pcs) and is the preferred KYOCERA AVX option for new production.

Q: Can I substitute the ECJ-2VB2A471K with KGM21NR72D471KT?

A: No. The KGM21NR72D471KT is rated for 200V, not 100V. While it maintains the same capacitance, tolerance, temperature coefficient, and package, the higher voltage rating makes it unsuitable as a direct substitute. Use only if circuit design requires 200V rated voltage.

Q: What is MSL 1 (Unlimited) and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitutes maintain MSL 1 classification, ensuring identical moisture management requirements.

Q: Which substitute offers the best value for high-volume production?

A: KGM21NR72A471KT (KYOCERA AVX) offers the highest inventory availability (185,065 pcs), ROHS3 compliance, and REACH unaffected status, making it optimal for volume production with minimal supply chain risk.
