ECJ-2VC2A150J Equivalent & Substitute Parts

Part Overview

The ECJ-2VC2A150J is a 15 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 and substitute parts necessary for ongoing design support and procurement. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering active product status from alternative manufacturers.

Substitute Part Grouping Explanation

Substitute parts are qualified based on strict electrical and mechanical parameter matching:

Electrical Equivalence Criteria:

Capacitance: 15 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 100V (exact match required)
Temperature Coefficient: C0G/NP0 (exact match required)
Operating Temperature: -55°C to 125°C (exact match required)

Mechanical Compatibility Criteria:

Package: 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 criteria. The upgrade part (08051A150GA12A) offers improved tolerance (±2% versus ±5%) and is included for applications requiring tighter capacitance control.

Engineering Selection Recommendations

Standard Substitutes (Direct Replacement): All parts listed as direct substitutes maintain full electrical and mechanical compatibility with the ECJ-2VC2A150J. Selection among these parts should be based on:

Availability and lead time from authorized distributors
ROHS3 compliance requirement (all direct substitutes except the upgrade part are ROHS3 compliant)
Packaging format preference (Tape & Reel available for all active parts)
Inventory levels and procurement cost

Upgrade Option: The 08051A150GA12A offers improved tolerance specification (±2% versus ±5%) for applications requiring tighter capacitance control. This part is RoHS non-compliant and REACH affected, limiting its use to applications without regulatory restrictions on hazardous substances.

Thickness Considerations: Substitute parts exhibit thickness variation from 0.70mm to 1.15mm. The original ECJ-2VC2A150J specifies 0.95mm maximum thickness. Parts with reduced thickness (0.70mm to 0.88mm) provide design flexibility for space-constrained applications. The KGQ21HCG2A150JT (1.15mm) is suitable only where additional height is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for ECJ-2VC2A150J?

A: Yes. All listed direct substitute parts maintain identical electrical specifications (15 pF ±5% 100V C0G/NP0) and mechanical compatibility (0805 package, surface mount MLCC, MSL 1). Physical dimensions are within acceptable tolerance for PCB footprints designed for 0805 components.

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

A: C0G and NP0 designate the same temperature coefficient characteristic. C0G is the EIA designation; NP0 is the IEC designation. Both terms describe zero temperature coefficient performance across the -55°C to 125°C operating range.

Q: Why do substitute parts have different thickness specifications?

A: Thickness variation results from different manufacturing processes and internal construction methods among manufacturers. All parts meet the 0805 package specification. Verify PCB clearance requirements for your specific application, particularly if using parts thinner than the original 0.95mm specification.

Q: Is the 08051A150GA12A upgrade part a suitable replacement?

A: The 08051A150GA12A is electrically compatible and mechanically compatible. The ±2% tolerance provides improved capacitance accuracy compared to the ±5% original specification. However, this part is RoHS non-compliant and REACH affected. Use only in applications without regulatory restrictions on hazardous substances.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 2011/65/EU as amended. All direct substitute parts except the upgrade option are ROHS3 compliant, suitable for applications with regulatory requirements for hazardous substance restriction.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All active substitute parts are available in Tape & Reel (TR) packaging format suitable for automated assembly processes.
