Key Parameters

Substitute Part Grouping Explanation

Substitution of the C323C104F3G5TA is permissible when the following conditions are met:

Mandatory Matching Parameters:

• Capacitance value: 0.1 µF (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required)
• Tolerance: ±1% or tighter
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Through hole radial configuration
• Lead spacing: 0.200" (5.08mm)
• RoHS compliance status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage rating: May be equal to or higher than 25V
• Physical dimensions: May vary if PCB layout permits
• Lead style: May differ (formed vs. kinked leads) if footprint accommodates

The C333C104F5G5TA qualifies as a substitute because it maintains all mandatory parameters while providing an elevated 50V voltage rating, enabling use in higher-voltage circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (C323C104F3G5TA): Use when circuit voltage requirements are 25V or lower and PCB space constraints require the smaller 0.300" seated height. This part maintains the most compact footprint within the GoldMax 300 Comm C0G series.

Substitute Selection (C333C104F5G5TA): Use when circuit design operates at voltages between 25V and 50V, or when higher voltage margin is required for system reliability. The substitute part accommodates the larger physical envelope (0.400" seated height) and kinked lead configuration. Both parts maintain identical electrical performance at 0.1 µF capacitance with C0G/NP0 stability across the -55°C to 125°C operating range.

Both parts carry active product status and full ROHS3 compliance, ensuring regulatory conformance and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can C333C104F5G5TA replace C323C104F3G5TA in all applications?

A: Electrical substitution is valid when PCB layout accommodates the larger physical dimensions (0.280" L x 0.160" W vs. 0.200" L x 0.125" W) and increased seated height (0.400" vs. 0.300"). Lead spacing remains identical at 0.200" (5.08mm), maintaining footprint compatibility. Verify available board space before substitution.

Q: What is the significance of the kinked lead style on the substitute part?

A: The kinked lead configuration on C333C104F5G5TA provides mechanical support during insertion into through-hole PCB positions. This variation does not affect electrical performance or functional compatibility when the PCB footprint is designed for radial through-hole mounting with 0.200" lead spacing.

Q: Why would a 50V-rated capacitor be used in a 25V circuit?

A: Higher voltage ratings provide operational margin and extended component life under transient voltage conditions. The 50V-rated C333C104F5G5TA operates identically to the 25V-rated C323C104F3G5TA at 25V and below, with no performance degradation. This substitution is valid when circuit design permits the larger physical envelope.

Q: Are both parts suitable for high-reliability applications?

A: Both C323C104F3G5TA and C333C104F5G5TA are ROHS3 compliant, active-status products from the GoldMax 300 Comm C0G series with identical operating temperature ranges (-55°C to 125°C) and C0G/NP0 temperature coefficient stability. Component selection should be based on voltage requirements and available PCB space rather than reliability classification.

Q: What is the impact of different physical sizes on circuit design?

A: The substitute part (C333C104F5G5TA) is larger in length, width, and height. PCB layout must accommodate these dimensions: 0.280" L x 0.160" W with 0.400" maximum seated height versus 0.200" L x 0.125" W with 0.300" maximum seated height for the main part. Lead spacing (0.200") remains constant, so existing footprints may require verification for clearance with adjacent components.
