ECJ-2VB2D102K Equivalent & Substitute Parts

Part Overview

The ECJ-2VB2D102K is a 1000 pF ±10% 200V ceramic capacitor in X7R temperature coefficient, 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 production and design requirements. The ECJ series has been discontinued, requiring engineers to source functionally equivalent alternatives from active manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the ECJ-2VB2D102K are grouped into two categories based on electrical parameters:

Direct Equivalents (200V Rating): Parts maintaining identical voltage rating, capacitance, tolerance, temperature coefficient, and package dimensions. These parts are pin-compatible and electrically interchangeable without circuit modification. Key parameters for direct substitution are: 1000 pF capacitance, ±10% tolerance, 200V voltage rating, X7R temperature coefficient, and 0805 package.

Upgrade Options (500V Rating): Parts with elevated voltage rating (500V) while maintaining all other electrical specifications. These provide enhanced voltage margin and are mechanically compatible with the 0805 footprint, though thickness may vary slightly. Upgrade parts are suitable when circuit design permits higher voltage components.

Engineering Selection Recommendations

For Direct Replacement (200V Equivalents):

KEMET C0805C102K2RAC7800 is the preferred direct equivalent. It maintains all electrical specifications, offers ROHS3 compliance, and has the lowest thickness profile (0.035" / 0.88mm), providing maximum PCB design flexibility. This part has the highest inventory availability (59,492 pcs) and is actively manufactured.

YAGEO CC0805KRX7RABB102 is an alternative direct equivalent with ROHS3 compliance and active product status. Thickness matches the original specification at 0.037" (0.95mm).

KYOCERA AVX KGM21NR72D102KT offers direct electrical equivalence with ROHS3 compliance and substantial inventory (10,723 pcs). Thickness is 0.039" (1.00mm), which remains within acceptable PCB assembly tolerances for 0805 packages.

KYOCERA AVX 08052C102KAJ2A and 08052C102KAJ4A are direct electrical equivalents with active status but are RoHS non-compliant. These are suitable for applications where RoHS compliance is not required.

For Voltage Upgrade (500V Options):

Knowles Syfer 0805J5000102KJT and 0805J5000102KXT provide 500V rating with ROHS3 compliance and active status. These are suitable for designs requiring enhanced voltage margin. Thickness increases to 0.051" (1.30mm), requiring PCB assembly process verification.

Knowles Novacap 0805B102K501NT offers 500V rating with ROHS3 compliance but has the highest thickness at 0.054" (1.37mm), requiring clearance verification in high-density layouts.

Frequently Asked Questions (FAQ)

Q: Can I use a 500V rated capacitor in place of the 200V ECJ-2VB2D102K?

A: Yes. A 500V rated capacitor is electrically compatible and provides additional voltage margin. However, verify PCB assembly clearance, as 500V variants have increased thickness (1.30mm to 1.37mm) compared to the original 0.95mm specification.

Q: What is the difference between direct equivalents and upgrade options?

A: Direct equivalents maintain the 200V rating and are pin-compatible with identical thickness profiles. Upgrade options provide 500V rating with increased thickness, suitable when circuit design permits higher voltage components and PCB layout allows additional height.

Q: Are all substitute parts compatible with the original 0805 footprint?

A: Yes. All listed substitutes use the 0805 (2012 Metric) package with identical length (0.079" / 2.00-2.01mm) and width (0.049" / 1.25mm). Thickness varies between 0.035" and 0.054", which is within standard PCB assembly tolerances for this package class.

Q: Which substitute offers the best RoHS compliance?

A: KEMET C0805C102K2RAC7800, YAGEO CC0805KRX7RABB102, KYOCERA AVX KGM21NR72D102KT, and all 500V upgrade options are ROHS3 compliant. KYOCERA AVX 08052C102KAJ2A, 08052C102KAJ4A, and LD052C102KAB4A are RoHS non-compliant.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited), identical to the original ECJ-2VB2D102K, requiring no special moisture handling or baking procedures.

Q: Can I mix different manufacturers' parts in the same production run?

A: Yes. All listed substitutes meet identical electrical specifications (1000 pF, ±10%, 200V or 500V, X7R, -55°C to 125°C). Verify PCB assembly process compatibility for thickness variations if mixing 200V and 500V variants.
