08055U2R2CAT2A Equivalent & Substitute Parts

Part Overview

The 08055U2R2CAT2A is a 2.2 pF ceramic capacitor manufactured by KYOCERA AVX, designed for RF, microwave, and high-frequency applications. This surface-mount MLCC (multilayer ceramic capacitor) operates at 50V rated voltage with C0G/NP0 temperature coefficient, ensuring stable capacitance across the -55°C to 125°C operating range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options while maintaining functional equivalence within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the 08055U2R2CAT2A is determined by strict equivalence in the following critical parameters:

• Capacitance Value: Must be 2.2 pF
• Tolerance: Must be ±0.25pF
• Temperature Coefficient: Must be C0G/NP0
• Package / Case: Must be 0805 (2012 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.079" L x 0.049" W (2.01mm x 1.25mm) and 0.045" (1.15mm) maximum thickness

The substitute part KGQ21HCG2D2R2CT meets all mechanical and electrical compatibility requirements. The rated voltage of the substitute (200V) exceeds the main part specification (50V), which is permissible as a higher voltage rating does not compromise circuit functionality in applications designed for 50V operation.

Parameter Comparison

Engineering Selection Recommendations

Both the 08055U2R2CAT2A and KGQ21HCG2D2R2CT are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The KGQ21HCG2D2R2CT substitute provides equivalent electrical and mechanical performance with higher voltage rating capability. Selection between these parts should be based on availability, lead time, and inventory requirements, as both parts satisfy the specified application parameters for RF and microwave circuits operating at or below 50V.

Frequently Asked Questions (FAQ)

Q: Can KGQ21HCG2D2R2CT be used as a direct replacement for 08055U2R2CAT2A?

A: Yes. Both parts share identical capacitance (2.2 pF), tolerance (±0.25pF), temperature coefficient (C0G/NP0), package (0805), and physical dimensions. The substitute's higher voltage rating (200V vs. 50V) does not prevent direct substitution in circuits designed for 50V operation.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts use identical 0805 (2012 Metric) surface-mount packages with matching dimensions (0.079" L x 0.049" W, 0.045" maximum thickness) and mounting type. PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The KGQ21HCG2D2R2CT's 200V rating provides additional design margin in applications where voltage stress may vary. This does not affect performance in circuits specified for 50V operation and may extend component reliability in marginal voltage conditions.

Q: Are there any performance differences in RF and microwave applications?

A: Both parts feature ultra-low ESR and C0G/NP0 temperature stability across -55°C to 125°C, meeting RF and microwave application requirements identically. No performance differentiation exists for these application categories.
