Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055U6R8CAT2A is determined by strict alignment of the following parameters:

• Capacitance Value: Must be 6.8 pF
• Tolerance: Must be ±0.25pF
• Temperature Coefficient: Must be C0G/NP0
• Operating Temperature Range: Must be -55°C ~ 125°C
• Package / Case: Must be 0805 (2012 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Features: Must include Ultra Low ESR
• RoHS & Compliance: Must maintain ROHS3 Compliant status

The voltage rating may vary upward from the original 50V specification, as higher-rated components remain functionally compatible in lower-voltage applications. The substitute part KGQ21HCG2D6R8CT meets all mandatory electrical and mechanical parameters while offering an elevated 200V voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Both the 08055U6R8CAT2A and KGQ21HCG2D6R8CT are Active production components manufactured by KYOCERA AVX with identical ROHS3 compliance and REACH unaffected status. The primary distinction is the voltage rating: the original part is rated 50V, while the substitute is rated 200V. Selection between these parts depends on circuit voltage requirements. The substitute part offers significantly higher inventory availability (14781 units versus 908 units), making it advantageous for supply chain continuity when voltage headroom permits its use. Both parts maintain identical physical dimensions, thermal characteristics, and ESR performance, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can KGQ21HCG2D6R8CT replace 08055U6R8CAT2A in a 50V circuit?

A: Yes. The KGQ21HCG2D6R8CT is rated for 200V and maintains all electrical parameters (capacitance, tolerance, temperature coefficient) identical to the original part. Higher voltage-rated capacitors operate safely in lower-voltage applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical length (0.079"), width (0.049"), and maximum thickness (0.045"). PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, with identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the primary advantage of the substitute part?

A: The KGQ21HCG2D6R8CT offers substantially higher inventory availability (14781 units in stock compared to 908 units) while maintaining identical electrical and mechanical specifications for RF and microwave applications.

Q: Are there any thermal or frequency performance differences?

A: No. Both parts operate across -55°C to 125°C with C0G/NP0 temperature stability and Ultra Low ESR characteristics, ensuring equivalent performance in RF and microwave circuits.
