C318C302K2G5TA Equivalent & Substitute Parts

Part Overview

The C318C302K2G5TA is a 3000 pF ceramic capacitor manufactured by KEMET, rated for 200V operation with C0G/NP0 temperature coefficient characteristics. This radial through-hole component is part of the GoldMax 300 Comm C0G series and is currently in active production status. The component features low ESL (Equivalent Series Inductance) and is designed for general-purpose applications requiring stable capacitance across temperature variations.

Substitute parts are identified when equivalent electrical performance can be achieved through alternative KEMET components that maintain the same capacitance value and temperature coefficient while potentially offering different voltage ratings, tolerances, or physical dimensions suited to specific circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the C318C302K2G5TA is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value must remain 3000 pF
• Temperature coefficient must be C0G/NP0 to maintain frequency and temperature stability
• Operating temperature range must encompass -55°C to 125°C
• Voltage rating must be equal to or greater than 200V

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Lead spacing must be 0.200" (5.08mm) to ensure PCB footprint compatibility

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required

The C323C302JAG5TA qualifies as a substitute part because it maintains identical capacitance, temperature coefficient, operating temperature range, mounting type, package configuration, and lead spacing. The substitute part offers enhanced voltage rating (250V versus 200V) and improved tolerance (±5% versus ±10%), providing greater design margin while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the C318C302K2G5TA and C323C302JAG5TA are active production components manufactured by KEMET and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by circuit voltage requirements and tolerance specifications.

The C318C302K2G5TA is appropriate for applications with 200V maximum operating voltage and where ±10% capacitance tolerance is acceptable.

The C323C302JAG5TA is appropriate for applications requiring higher voltage margin (250V rating) or improved capacitance accuracy (±5% tolerance). The substitute part provides enhanced performance specifications while maintaining identical electrical behavior and mechanical compatibility. Both components are suitable for general-purpose applications requiring stable capacitance across the full -55°C to 125°C temperature range.

Physical dimensions differ between the two parts. The C323C302JAG5TA has larger body dimensions (0.200" L x 0.125" W versus 0.150" L x 0.100" W) and greater seated height (0.300" versus 0.235"), which must be verified against available PCB space before substitution.

Frequently Asked Questions (FAQ)

Q: Can the C323C302JAG5TA be used as a direct replacement for the C318C302K2G5TA?

A: The C323C302JAG5TA is electrically compatible and maintains the same lead spacing (0.200"), but physical dimensions are larger. PCB layout space must accommodate the increased body size (0.200" L x 0.125" W) and seated height (0.300") before substitution.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G and NP0 designations indicate zero temperature coefficient, meaning capacitance remains stable across the -55°C to 125°C operating range. This characteristic is maintained in both the main part and substitute part.

Q: Why does the C323C302JAG5TA have a higher voltage rating?

A: The substitute part is rated for 250V operation compared to 200V for the main part. This higher rating provides additional design margin and allows use in higher voltage applications while maintaining identical capacitance and temperature stability.

Q: Is the ±5% tolerance of the C323C302JAG5TA better than the ±10% tolerance of the C318C302K2G5TA?

A: The ±5% tolerance specification represents tighter capacitance accuracy. Applications requiring precise capacitance values benefit from this improved tolerance, though both tolerances are within the C0G/NP0 ceramic capacitor standard range.

Q: Are both parts RoHS3 compliant?

A: Both the C318C302K2G5TA and C323C302JAG5TA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the lead spacing specification and why is it important?

A: Both parts feature 0.200" (5.08mm) lead spacing, which determines PCB footprint compatibility. This identical spacing ensures both components fit the same through-hole pad pattern.

Q: Can these parts be used interchangeably in all applications?

A: Electrical interchangeability is confirmed for applications operating at or below 200V. Physical dimensions must be verified for PCB layout compatibility. The substitute part's larger body size may require layout modifications in space-constrained designs.
