Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 08055U470JAT2A are qualified based on the following fixed parameters:

• Capacitance: 47 pF (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowed Variations:

• Voltage Rating: Substitute parts rated at 200V are acceptable as they exceed the 50V requirement of the main part
• Tolerance: Substitute parts with ±1% or ±2% tolerance are acceptable as they meet or exceed the ±5% tolerance of the main part

All three substitute parts (KGQ21HCG2D470JT, KGQ21HCG2D470FT, KGQ21HCG2D470GT) meet these criteria and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active production components from KYOCERA AVX with ROHS3 compliance and identical MSL ratings. Selection between substitutes depends on application-specific tolerance and voltage requirements:

KGQ21HCG2D470JT provides ±5% tolerance matching the original part specification with elevated 200V rating, suitable for applications requiring higher voltage margin without tolerance improvement.

KGQ21HCG2D470FT offers ±1% tolerance with 200V rating, appropriate for precision RF and microwave circuits where tighter capacitance tolerance improves frequency stability and performance predictability.

KGQ21HCG2D470GT provides ±2% tolerance with 200V rating, balancing tolerance improvement and cost considerations for applications requiring better accuracy than ±5% but not requiring ±1% specification.

All substitute parts maintain identical physical dimensions, thermal characteristics, and ultra-low ESR performance required for RF, microwave, and high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can KGQ21HCG2D470JT, KGQ21HCG2D470FT, or KGQ21HCG2D470GT be used as direct replacements for 08055U470JAT2A?

A: Yes. All three parts share identical capacitance (47 pF), temperature coefficient (C0G/NP0), package (0805), operating temperature range (-55°C ~ 125°C), and compliance certifications. The 200V rating exceeds the 50V requirement, and improved or matching tolerance specifications ensure functional compatibility.

Q: What is the difference between the three substitute parts?

A: The primary differences are tolerance and voltage rating. KGQ21HCG2D470JT matches the ±5% tolerance of the original part. KGQ21HCG2D470FT provides ±1% tolerance for precision applications. KGQ21HCG2D470GT offers ±2% tolerance as a middle option. All three are rated for 200V compared to the original 50V rating.

Q: Are there any physical or mechanical differences between these parts?

A: No. All parts share identical dimensions (0.079" L x 0.049" W / 2.01mm x 1.25mm), maximum thickness (0.045" / 1.15mm), and 0805 (2012 Metric) package specification. They are mechanically interchangeable on PCBs designed for the original part.

Q: Do these substitute parts have the same MSL rating?

A: Yes. All parts, including the original 08055U470JAT2A, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.

Q: Are all parts ROHS3 compliant?

A: Yes. The original part and all three substitutes are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: Which substitute should I select for RF and microwave applications?

A: All three substitutes are suitable for RF, microwave, and high-frequency applications due to ultra-low ESR performance. Selection depends on tolerance requirements: use KGQ21HCG2D470FT (±1%) for precision frequency-critical circuits, KGQ21HCG2D470GT (±2%) for general RF applications, or KGQ21HCG2D470JT (±5%) when tolerance matching the original specification is acceptable.
