Substitute Part Grouping Explanation

Substitution for the ECJ-2VC1H820J is determined by strict equivalence across the following parameters:

Capacitance value: 82 pF (exact match required)
Tolerance: ±5% or tighter
Voltage rating: 50V minimum
Temperature coefficient: C0G or NP0 designation
Package: 0805 (2012 Metric) surface mount
Operating temperature range: -55°C to 125°C minimum
Mounting type: Surface mount MLCC

Direct substitutes maintain all electrical and mechanical specifications. Upgrade parts exceed the original specifications in voltage rating or tolerance while maintaining all other parameters. All substitute parts are RoHS3 compliant and MSL 1 rated.

Engineering Selection Recommendations

Direct substitutes with equivalent 50V rating and ±5% tolerance are preferred for drop-in replacement: 08055A820JAT2M (KYOCERA AVX), C0805C820J5GAC7800 (KEMET), CC0805JRNPO9BN820 (YAGEO), KGM21BCG1H820JT (KYOCERA AVX), and VJ0805A820JXACW1BC (Vishay Vitramon). All direct substitutes are active production parts with RoHS3 compliance and MSL 1 rating.

AC0805JRNPO9BN820 (YAGEO) is suitable for automotive applications, carrying AEC-Q200 qualification while maintaining equivalent electrical specifications.

Upgrade parts C0805C820F1GAC7800, C0805C820F2GAC7800, and C0805C820F5GAC7800 (KEMET) provide enhanced tolerance (±1%) and higher voltage ratings (100V or 200V) while maintaining the 82 pF capacitance and 0805 package. These are applicable where design margins permit higher voltage ratings or tighter tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 50V specification?

A: Yes. Higher voltage ratings are electrically compatible and provide additional design margin. Parts rated for 100V or 200V can replace the 50V original in applications where board space and height constraints permit.

Q: What is the significance of the ±1% tolerance upgrade parts?

A: Upgrade parts with ±1% tolerance provide tighter capacitance control compared to the original ±5% specification. This is beneficial in precision circuits where capacitance accuracy is critical, though not required for general-purpose applications.

Q: Are all substitute parts suitable for automotive applications?

A: Only AC0805JRNPO9BN820 carries AEC-Q200 automotive qualification. Other substitutes are suitable for general-purpose and industrial applications. Automotive designs should specify AC0805JRNPO9BN820 or verify alternative part qualifications with the manufacturer.

Q: What is the impact of thickness variation among substitute parts?

A: Thickness varies from 0.024" (0.60mm) to 0.037" (0.94mm). Verify PCB assembly equipment and design clearances accommodate the selected substitute. Thinner parts (YAGEO CC0805JRNPO9BN820 at 0.024") may offer advantages in space-constrained designs.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available?

A: Direct substitutes are available in Tape & Reel (TR) and Cut Tape (CT) formats. Verify packaging compatibility with procurement and assembly processes before selection.
