Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08052A820KAJ2A is determined by the following critical parameters:

• Capacitance Value: Must be 82 pF (exact match required)
• Temperature Coefficient: Must be C0G or NP0 (equivalent specifications)
• Package / Case: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Voltage Rating: Must be equal to or greater than 200V
• Tolerance: ±5% or tighter tolerance is acceptable as an upgrade
• Moisture Sensitivity Level: Must be 1 (Unlimited) or equivalent

The identified substitute parts meet these criteria while offering improved regulatory compliance and tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

KGM21BCG2D820JT (KYOCERA AVX): This substitute maintains identical voltage rating (200V) and operating temperature range while providing improved tolerance (±5% versus ±10%). The part achieves ROHS3 compliance and REACH Unaffected status, addressing regulatory requirements of the original part. Same manufacturer ensures consistent electrical and mechanical characteristics.

C0805C820JAGAC7800 (KEMET): This substitute provides elevated voltage rating (250V versus 200V), offering additional design margin. Tolerance is improved to ±5%, and the part is ROHS3 compliant with REACH Unaffected status. The Low ESL feature is provided as an additional specification. Mechanical dimensions remain compatible with 0805 package requirements.

Both substitutes are electrically and mechanically compatible with the 08052A820KAJ2A and support identical operating temperature ranges and package specifications.

Frequently Asked Questions (FAQ)

Q: Can KGM21BCG2D820JT replace 08052A820KAJ2A in all applications?

A: Yes. Both parts share identical capacitance (82 pF), voltage rating (200V), temperature coefficient (C0G/NP0), package (0805), and operating temperature range (-55°C ~ 125°C). The substitute offers tighter tolerance (±5% versus ±10%) and improved regulatory compliance.

Q: What is the advantage of C0805C820JAGAC7800 over the main part?

A: The KEMET substitute provides higher voltage rating (250V versus 200V), tighter tolerance (±5% versus ±10%), and ROHS3/REACH compliance. The elevated voltage rating provides additional safety margin in circuit design.

Q: Are the physical dimensions identical across all three parts?

A: All three parts conform to 0805 (2012 Metric) package specification. Dimensional variations within tolerance (length 0.079" ± tolerance, width 0.049" ± tolerance) are acceptable for PCB assembly and do not affect interchangeability.

Q: Does tolerance difference affect circuit performance?

A: Tolerance affects capacitance accuracy. The ±10% tolerance of 08052A820KAJ2A allows capacitance range of 73.8 pF to 90.2 pF. The ±5% tolerance of substitutes narrows this to 77.9 pF to 86.1 pF. Select based on circuit requirements for capacitance accuracy.

Q: What is the significance of RoHS and REACH compliance?

A: ROHS3 compliance indicates the part contains no restricted substances (lead, cadmium, mercury, etc.). REACH Unaffected status indicates the part is not subject to REACH chemical restrictions. These certifications are required for many industrial and consumer applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the tolerance specifications. If the original design requires ±10% tolerance, both substitutes with ±5% tolerance are acceptable. If higher voltage margin is beneficial, C0805C820JAGAC7800 (250V) is suitable for 200V-rated circuits.
