ECJ-2VC2A101J Equivalent & Substitute Parts

Part Overview

The ECJ-2VC2A101J is a 100 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by Panasonic Electronic Components in 0805 (2012 Metric) surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and design requirements. 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: 100 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 100V (exact match required)
Temperature Coefficient: C0G/NP0 (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria. Variations in physical dimensions (length, width, thickness) within standard tolerances, RoHS compliance status, and REACH classification do not affect electrical substitutability but may impact assembly and regulatory requirements.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the ECJ-2VC2A101J. Selection should be based on product availability, compliance requirements, and assembly constraints:

For RoHS3 Compliant Applications: KYOCERA AVX 08051A101JAT2M, 08051A101JAT4P; Venkel C0805C0G101-101JNE, C0805C0G101-101JNP; KEMET C0805C101J1GAC7800; YAGEO CC0805JPNPO0BN101, CC0805JRNPO0BN101.

For Non-RoHS Applications: KYOCERA AVX 08051A101JA12A, 08051A101JAJ2A; KEMET C0805C101J1GAL7800.

For Space-Constrained Designs: YAGEO CC0805JPNPO0BN101 and CC0805JRNPO0BN101 offer minimum thickness at 0.70mm. KEMET C0805C101J1GAC7800 and C0805C101J1GAL7800 provide 0.88mm thickness.

For Standard Thickness Applications: Venkel parts provide 1.40mm thickness; KYOCERA AVX parts provide 0.94mm thickness.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ECJ-2VC2A101J with any of the listed parts?

A: Yes. All listed parts meet the electrical and mechanical specifications required for direct substitution: 100 pF capacitance, ±5% tolerance, 100V rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, 0805 package, and MSL 1 rating.

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

A: C0G and NP0 designations are equivalent specifications from different manufacturers. Both indicate zero temperature coefficient performance across the operating temperature range.

Q: Does thickness variation affect substitutability?

A: Thickness variations within the listed range (0.70mm to 1.40mm) do not affect electrical performance. Selection depends on available PCB clearance and assembly equipment capabilities. Verify clearance for parts with maximum thickness of 1.40mm (Venkel).

Q: What is the significance of RoHS compliance status?

A: RoHS3 compliance is a regulatory requirement for products sold in certain markets. Non-compliant parts may be restricted depending on end-use application and regional regulations. Select ROHS3 Compliant parts for regulated applications.

Q: Are REACH-affected and REACH-unaffected parts interchangeable?

A: Yes, from an electrical and mechanical standpoint. REACH status indicates regulatory classification but does not affect component performance or substitutability. Selection depends on supply chain and regulatory requirements.

Q: What packaging options are available?

A: Substitute parts are available in Tape & Reel (TR) and standard packaging. Verify packaging compatibility with your assembly process requirements.
