Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter compatibility:

Direct Substitutes maintain all electrical specifications identical to the main part: 0.082 µF capacitance, ±10% tolerance, 16V voltage rating, and X7R temperature coefficient. These parts are mechanically and electrically interchangeable within the same 0805 package footprint. Direct substitutes include C0805C823K4RAC7800 (KEMET), KGM21NR71C823KM and KGM21NR71C823KT (KYOCERA AVX), VJ0805Y823KXJCW1BC, and VJ0805Y823KXJPW1BC (Vishay Vitramon).

Upgrade Substitutes increase either voltage rating or tolerance specification while maintaining the same capacitance value and package. These parts are suitable for applications where enhanced performance margins are acceptable or beneficial. Upgrade options include C0805C823J4RAC7800 (16V, ±5%), C0805C823J3RAC7800 (25V, ±5%), C0805C823J5RAC7800 (50V, ±5%), and C0805C823J1RAC7800 (100V, ±5%), all manufactured by KEMET.

Engineering Selection Recommendations

Direct Substitutes for Pin-Compatible Replacement:

C0805C823K4RAC7800 (KEMET) and KGM21NR71C823KT (KYOCERA AVX) are recommended as primary direct substitutes. Both maintain identical electrical specifications and are ROHS3 compliant with active product status. KEMET C0805C823K4RAC7800 offers 955 units in stock with Tape & Reel packaging. KYOCERA AVX KGM21NR71C823KT provides 876 units with equivalent specifications and REACH compliance.

VJ0805Y823KXJPW1BC (Vishay Vitramon) offers the highest inventory availability at 1000 units and features the thinnest profile at 0.035" (0.90mm), beneficial for space-constrained applications. All direct substitutes are ROHS3 compliant and MSL 1 rated.

Upgrade Substitutes for Enhanced Performance Margins:

C0805C823J5RAC7800 (KEMET, 50V, ±5%) provides the highest inventory availability at 4580 units with improved tolerance specification.

Frequently Asked Questions (FAQ)

Q: Can I use C0805C823K4RAC7800 as a direct replacement for ECJ-2VB1C823K?

A: Yes. C0805C823K4RAC7800 maintains identical electrical specifications: 0.082 µF capacitance, ±10% tolerance, 16V voltage rating, and X7R temperature coefficient in the same 0805 package. The 0.004" (0.05mm) thickness difference is within standard PCB assembly tolerances.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (C0805C823K4RAC7800, KGM21NR71C823KT, VJ0805Y823KXJPW1BC) match all electrical parameters of the original part. Upgrade substitutes increase voltage rating or tolerance specification while maintaining 0.082 µF capacitance. Upgrades are suitable only when application design permits higher voltage or tighter tolerance specifications.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original Panasonic ECJ-2VB1C823K does not specify ROHS status due to obsolete product classification.

Q: Which substitute offers the best availability?

A: C0805C823K1RAC7800 (KEMET, 100V upgrade) provides the highest inventory at 162,033 units. For direct electrical equivalents, VJ0805Y823KXJPW1BC (Vishay Vitramon) offers 1000 units.

Q: Does package thickness affect PCB assembly compatibility?

A: All parts use the 0805 (2012 Metric) package with thickness variations between 0.035" and 0.043". These differences are within standard reflow oven and pick-and-place equipment tolerances. Verify with your assembly partner if height-constrained applications exist.

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

A: Yes. All direct substitutes maintain identical electrical specifications and package footprint. Mixing manufacturers is acceptable provided all parts meet the same MSL 1 and ROHS3 compliance requirements.
