Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055U101GAT2A is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance: 100 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 Variation Parameters:

• Voltage Rating: Equal to or greater than 50V
• Tolerance: ±2% or tighter (±1% acceptable)
• RoHS Status: ROHS3 Compliant (maintained across all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained across all substitutes)

All identified substitute parts maintain identical capacitance, temperature coefficient, package dimensions, and operating temperature specifications. Variations in voltage rating and tolerance represent upgrades or alternative specifications within the same product family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between the main part and substitutes depends on application voltage requirements and tolerance specifications:

08055U101FAT2A provides identical voltage rating (50V) with improved tolerance (±1% versus ±2%), suitable for applications requiring tighter capacitance accuracy within the same voltage envelope.

KGQ21HCG2A101FT offers increased voltage rating (100V) with ±1% tolerance, applicable to circuits operating at higher voltage levels while maintaining the same capacitance value and temperature stability.

KGQ21HCG2D101GT provides maximum voltage rating (200V) with ±2% tolerance, designated for high-voltage circuit applications requiring the same 100 pF capacitance and C0G/NP0 stability.

All parts are manufactured by KYOCERA AVX and share identical physical dimensions, mounting characteristics, and thermal performance specifications.

Frequently Asked Questions (FAQ)

Q: Can 08055U101FAT2A replace 08055U101GAT2A in my circuit?

A: Yes. Both parts are identical in capacitance (100 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and package (0805). The 08055U101FAT2A offers tighter tolerance (±1% versus ±2%), making it a direct substitute with improved specification.

Q: What is the difference between the KGQ21HCG2A101FT and KGQ21HCG2D101GT substitutes?

A: Both maintain 100 pF capacitance and C0G/NP0 temperature coefficient in 0805 package. The KGQ21HCG2A101FT is rated for 100V with ±1% tolerance, while KGQ21HCG2D101GT is rated for 200V with ±2% tolerance. Selection depends on the maximum voltage present in your circuit.

Q: Can I use a higher voltage-rated substitute in a 50V circuit?

A: Yes. Higher voltage ratings are backward compatible. A 100V or 200V rated capacitor operates safely in a 50V circuit. Voltage rating indicates the maximum voltage the component can withstand; operating below this rating does not degrade performance.

Q: Are all substitute parts in the same 0805 package?

A: Yes. All parts listed—08055U101GAT2A, 08055U101FAT2A, KGQ21HCG2A101FT, and KGQ21HCG2D101GT—are packaged in 0805 (2012 Metric) with identical physical dimensions (0.079" L x 0.049" W, 2.01mm x 1.25mm) and maximum thickness (0.045", 1.15mm). They are mechanically interchangeable on PCBs designed for 0805 components.

Q: Do all substitutes maintain the same operating temperature range?

A: Yes. All parts operate across -55°C to 125°C, ensuring thermal performance consistency across the entire substitute family.

Q: Are all parts RoHS compliant?

A: Yes. All parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory requirements.
