Substitute Part Grouping Explanation

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

Capacitance value: 0.082 µF (exact match required)
Tolerance: ±10% (direct equivalents) or ±5% (upgrade option with improved tolerance)
Voltage rating: 50V minimum (63V represents an upgrade option)
Temperature coefficient: X7R (required for thermal stability matching)
Package: 0805 (2012 Metric) (physical and electrical compatibility)
Mounting type: Surface Mount, MLCC (assembly process compatibility)
Moisture sensitivity: MSL 1 (handling and storage equivalence)

Direct substitutes maintain all parameters identical to the main part. Upgrade options provide improved tolerance (±5%) or higher voltage rating (63V) while maintaining all other specifications.

Engineering Selection Recommendations

Direct substitutes (08055C823KAJ2A, 0805J0500823KXT, C0805C823K5RAC7800, CC0805KRX7R9BB823, CL21B823KBCNNNC, CL21B823KBFNNNE, CL21B823KBFNNNG, KGM21NR71H823KT) are electrically and mechanically equivalent to ECJ-2FB1H823K and support identical circuit performance.

For new designs requiring regulatory compliance, ROHS3-compliant options include 0805J0500823KXT, C0805C823K5RAC7800, CC0805KRX7R9BB823, CL21B823KBCNNNC, CL21B823KBFNNNE, CL21B823KBFNNNG, and KGM21NR71H823KT. The KYOCERA AVX part 08055C823KAJ2A is RoHS non-compliant and REACH-affected.

Upgrade options with improved tolerance (±5%) are available from Knowles Syfer: 0805J0500823JXT maintains 50V rating, while 0805J0630823JXT provides higher voltage rating (63V) with tighter tolerance. Both upgrade options are ROHS3 compliant and REACH unaffected.

All substitute parts maintain MSL 1 rating, supporting unlimited shelf life and standard handling procedures.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±5% tolerance instead of ±10%?

A: Yes. Parts 0805J0500823JXT and 0805J0630823JXT offer ±5% tolerance, which is a tighter specification than the original ±10% requirement. This represents an upgrade in tolerance performance while maintaining all other electrical parameters.

Q: What is the difference between the 50V and 63V rated parts?

A: The 0805J0630823JXT provides a higher voltage rating (63V) compared to the standard 50V specification. This allows operation in circuits with higher voltage stress margins. The 63V part is suitable for applications where the original 50V rating is insufficient, while maintaining identical capacitance and tolerance specifications.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Thickness variations exist among substitutes (ranging from 0.037" to 0.057" maximum), but these differences do not affect PCB assembly compatibility for standard surface mount processes.

Q: Which substitute parts are suitable for new product designs?

A: For new designs, prioritize active-status parts with ROHS3 compliance: 0805J0500823KXT, C0805C823K5RAC7800, CC0805KRX7R9BB823, CL21B823KBCNNNC, CL21B823KBFNNNE, CL21B823KBFNNNG, and KGM21NR71H823KT. These parts support current regulatory requirements and long-term supply availability.

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

A: All parts, including the original ECJ-2FB1H823K and all substitutes, carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

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

A: Yes. All substitute parts meet identical electrical specifications (0.082 µF ±10%, 50V, X7R, -55°C to 125°C) and physical package requirements (0805 2012 Metric, Surface Mount MLCC). Cross-manufacturer substitution is supported for equivalent parts.
