ECJ-2VC2A470J Equivalent & Substitute Parts

Part Overview

The ECJ-2VC2A470J is a 47 pF ceramic capacitor rated at 100V with C0G/NP0 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 ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Capacitance Value: 47 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 100V minimum (equal or higher acceptable)
Temperature Coefficient: C0G/NP0 (exact match required)
Operating Temperature Range: -55°C ~ 125°C minimum (equal or wider acceptable)
Package / Case: 0805 (2012 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All listed substitute parts meet these core electrical and mechanical requirements. The 0805D470J101KHT from Knowles Novacap is classified as an upgrade option due to its extended operating temperature range (-55°C ~ 200°C), which exceeds the original specification while maintaining all other parameters.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for ECJ-2VC2A470J?

A: Yes, all listed direct substitute parts maintain identical capacitance (47 pF), tolerance (±5%), voltage rating (100V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), and 0805 package specifications. Physical dimensions vary slightly in thickness; verify PCB clearance if space constraints exist.

Q: What is the difference between the YAGEO CC0805JPNPO0BN470 and CC0805JRNPO0BN470?

A: Both parts are electrically and mechanically equivalent with identical specifications. The primary difference is inventory availability: CC0805JRNPO0BN470 has 12,872 pcs in stock versus 1,084 pcs for CC0805JPNPO0BN470.

Q: Why is the 0805D470J101KHT listed as an upgrade?

A: The 0805D470J101KHT extends the operating temperature range to -55°C ~ 200°C, exceeding the original -55°C ~ 125°C specification. This provides additional thermal margin for high-temperature applications. However, its increased thickness (0.054" vs. 0.037") requires verification of PCB layout clearance.

Q: Are all substitute parts RoHS3 compliant?

A: Most substitute parts are ROHS3 compliant. The exception is 08051A470JAJ2A (KYOCERA AVX), which is RoHS non-compliant. Select RoHS3 compliant alternatives if regulatory compliance is required.

Q: Does thickness variation affect circuit performance?

A: Thickness variation does not affect electrical performance. Verify PCB layout clearance, particularly for the 0805D470J101KHT at 0.054" thickness. Thinner alternatives (0.028" ~ 0.035") may provide design flexibility for space-constrained applications.

Q: Which substitute part has the highest inventory availability?

A: KGM21BCG2A470JT (KYOCERA AVX) has the highest inventory at 197,522 pcs, followed by CC0805JRNPO0BN470 (YAGEO) at 12,872 pcs.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications and 0805 package requirements. Mixing is acceptable from an electrical standpoint; however, verify manufacturing process compatibility and quality documentation if required by your assembly procedures.
