Key Parameters

Substitute Part Grouping Explanation

Substitute parts for 08055U100JAT2A are qualified based on the following fixed parameters:

• Capacitance: 10 pF (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Allowable variations in substitute parts:

• Voltage Rating: May be equal to or higher than 50V
• Tolerance: May be tighter (±1%, ±2%) or equal (±5%) to the original specification

All substitute parts are manufactured by KYOCERA AVX and maintain identical physical dimensions, electrical characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full compliance with ROHS3, REACH Unaffected, and EAR99 classifications. Selection among substitute parts depends on circuit voltage requirements and tolerance specifications:

KGQ21HCG2A100FT provides 100V rating with ±1% tolerance, suitable for applications requiring tighter capacitance tolerance at moderate voltage levels.

KGQ21HCG2D100FT and KGQ21HCG2D100JT both provide 200V rating, with KGQ21HCG2D100FT offering ±1% tolerance for precision applications and KGQ21HCG2D100JT offering ±5% tolerance matching the original specification.

KGQ21HCG2D100GT provides 200V rating with ±2% tolerance as an intermediate option.

All substitute parts are electrically and mechanically interchangeable with 08055U100JAT2A in applications where the higher voltage rating does not create design constraints.

Frequently Asked Questions (FAQ)

Q: Can KGQ21HCG2D100FT replace 08055U100JAT2A directly?

A: Yes. KGQ21HCG2D100FT is electrically and mechanically compatible. It maintains identical capacitance (10 pF), temperature coefficient (C0G/NP0), package (0805), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (200V vs. 50V) and tighter tolerance (±1% vs. ±5%) do not prevent direct substitution.

Q: What is the difference between the substitute parts?

A: Substitute parts differ in voltage rating and tolerance. KGQ21HCG2A100FT is rated 100V with ±1% tolerance. KGQ21HCG2D100FT and KGQ21HCG2D100JT are both rated 200V, with the former offering ±1% tolerance and the latter ±5% tolerance. KGQ21HCG2D100GT is rated 200V with ±2% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the 0805 (2012 Metric) surface mount package with identical dimensions (0.079" L x 0.049" W, 2.01mm x 1.25mm) and maximum thickness (0.045", 1.15mm).

Q: Do substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including 08055U100JAT2A and all substitute parts, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Can I use a substitute part with higher voltage rating in a 50V circuit?

A: Yes. Using a higher voltage-rated capacitor in a lower voltage application is standard practice. The 100V and 200V rated substitutes are fully compatible with 50V circuits.
