ECJ-2VC2A151J Equivalent & Substitute Parts

Part Overview

The ECJ-2VC2A151J is a 150 pF ±5% 100V ceramic capacitor 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 substitute parts 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: 150 pF
Tolerance: ±5%
Voltage rating: 100V minimum
Temperature coefficient: C0G or NP0 designation
Operating temperature range: -55°C to 125°C minimum
Package: 0805 (2012 Metric) surface mount
Moisture sensitivity: MSL 1 or better

All listed substitute parts meet these core electrical and mechanical requirements. Variations in thickness, RoHS compliance status, and product lifecycle status are noted but do not affect functional substitutability for the specified application parameters.

Engineering Selection Recommendations

For new production designs, select from parts with Active product status and ROHS3 compliance. KEMET C0805C151J1GAC7800, YAGEO CC0805JPNPO0BN151 and CC0805JRNPO0BN151, KYOCERA AVX KGM21BCG2A151JT, and Vishay Vitramon VJ0805A151JXBCW1BC and VJ0805A151JXBPW1BC are all suitable for long-term supply chain stability.

For existing inventory replacement or maintenance applications, KYOCERA AVX 08051A151JA12A and 08051U151JAT2A provide direct electrical equivalence. The 08051U151JAT2A variant includes Ultra Low ESR characteristics and is ROHS3 compliant.

Murata GRM2165C2A151JA01D is marked "Not For New Designs" and should be used only for legacy system maintenance where original part sourcing is exhausted.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECJ-2VC2A151J?

A: Yes. All listed parts meet the core electrical specifications: 150 pF capacitance, ±5% tolerance, 100V rating, C0G/NP0 temperature coefficient, and 0805 package. Mechanical fit is confirmed across all variants.

Q: What is the significance of thickness variations (0.028" to 0.045")?

A: Thickness differences fall within acceptable PCB assembly tolerances for 0805 components. Verify your PCB design clearance specifications if space constraints exist. Most applications accommodate the full range without modification.

Q: Why is GRM2165C2A151JA01D marked "Not For New Designs"?

A: This designation indicates the manufacturer recommends against using this part for new product development. It remains functionally equivalent and suitable for maintenance or legacy system repairs where supply continuity is the priority.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant parts?

A: ROHS3 compliant parts meet current regulatory requirements for hazardous substance restrictions. RoHS non-compliant parts may contain restricted materials. For applications subject to regulatory compliance requirements, select ROHS3 compliant alternatives.

Q: Are there differences in ESR or frequency characteristics between these parts?

A: The 08051U151JAT2A is specified with Ultra Low ESR characteristics. Standard variants are not differentiated by ESR in the provided specifications. For RF, microwave, or high-frequency applications requiring specific ESR performance, the 08051U151JAT2A is designated for these uses.

Q: What packaging format should I specify for procurement?

A: All substitute parts are available in Tape & Reel (TR) format for automated assembly. Confirm your procurement system accepts this standard packaging format.
