C320C511G3G5TA Equivalent & Substitute Parts

Part Overview

The C320C511G3G5TA is a 510 pF ceramic capacitor manufactured by KEMET, part of the GoldMax 300 Comm C0G series. This through-hole radial capacitor operates at 25V rated voltage with ±2% tolerance and C0G/NP0 temperature coefficient, suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The component is ROHS3 compliant and currently in active production status with 864 units in stock. Equivalent and substitute parts are identified when identical or higher electrical ratings can accommodate the original application requirements while maintaining mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C320C511G3G5TA is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 510 pF (exact match required)
• Tolerance: ±2% (equal or tighter acceptable)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Lead Spacing: 0.100" (2.54mm) (exact match required for PCB footprint compatibility)
• Operating Temperature Range: -55°C to 125°C (equal or wider acceptable)

Allowable Variation:

• Voltage Rating: Equal or higher than 25V (higher voltage ratings provide additional design margin and are electrically compatible in lower-voltage applications)

Compliance Requirements:

• RoHS3 compliance must be maintained
• REACH unaffected status must be maintained

The C315C511G1G5TA qualifies as a substitute because it maintains all mandatory parameters while providing an elevated voltage rating of 100V, which is compatible with the original 25V application. The physical dimensions are smaller, but lead spacing remains identical at 0.100" (2.54mm), ensuring PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (C320C511G3G5TA): Select the C320C511G3G5TA when the original design specifications explicitly require a 25V rated component and the larger physical dimensions are acceptable for the PCB layout. This part is in active production with 864 units in current inventory.

Substitute Selection (C315C511G1G5TA): The C315C511G1G5TA is electrically and mechanically compatible as a substitute. The 100V voltage rating provides additional design margin for applications where voltage stress is a consideration. The reduced physical dimensions (0.150" L x 0.100" W versus 0.200" L x 0.125" W) and lower seated height (0.183" versus 0.290") make this substitute suitable for space-constrained PCB layouts. Both parts maintain identical lead spacing (0.100" / 2.54mm), ensuring direct PCB footprint compatibility. The substitute is available in higher quantity (8168 units in stock). Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the C315C511G1G5TA replace the C320C511G3G5TA in all applications?

A: Yes, the C315C511G1G5TA is electrically compatible as a substitute. The 100V rating accommodates the original 25V application requirement. The identical lead spacing (0.100" / 2.54mm) ensures PCB footprint compatibility. The smaller physical dimensions may provide layout advantages in space-constrained designs.

Q: What is the difference between the two parts?

A: The primary differences are voltage rating (25V versus 100V) and physical dimensions. The C315C511G1G5TA is smaller in length, width, and seated height. All other electrical parameters—capacitance (510 pF), tolerance (±2%), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C)—are identical.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing of 0.100" (2.54mm), which determines PCB hole pattern compatibility. The substitute's smaller body dimensions do not affect footprint compatibility and may provide additional clearance in the PCB layout.

Q: Are both parts RoHS compliant?

A: Yes. Both the C320C511G3G5TA and C315C511G1G5TA are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent applications.

Q: Why would I choose the substitute over the main part?

A: The C315C511G1G5TA offers higher voltage rating (100V), smaller physical dimensions, lower profile height, and greater inventory availability (8168 units versus 864 units). These factors may provide design flexibility, improved PCB layout efficiency, and supply chain advantages.

Q: Can I use the main part where the substitute is specified?

A: No. The main part (C320C511G3G5TA) has a lower voltage rating (25V) than the substitute (100V). Using a lower-rated component in place of a higher-rated specification violates design requirements and may compromise circuit reliability.
