Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the M15G330K2 is based on strict electrical and mechanical parameter matching. All substitute parts maintain the core electrical specifications: 33 pF capacitance, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. The critical substitution parameters are:

Electrical Compatibility:

• Capacitance value must be 33 pF
• Temperature coefficient must be C0G/NP0
• Voltage rating must be 200V or higher
• Tolerance must be ±10% or tighter

Mechanical Compatibility:

• Mounting type must be through-hole radial
• Lead spacing must be 0.100" (2.54mm)
• Lead style must be straight

Compliance Enhancement:

• All KEMET substitutes are ROHS3 compliant, addressing the non-compliant status of the original M15G330K2
• All substitutes maintain EAR99 ECCN and 8532.24.0060 HTSUS classifications

Substitutes are grouped into two physical size categories based on body dimensions: C315C series (0.150" L x 0.100" W) and C320C series (0.200" L x 0.125" W). Within each size category, substitutes are available with voltage ratings of 200V or 250V and tolerance grades ranging from ±1% to ±10%.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent (Same Voltage Rating):

For applications requiring exact voltage matching at 200V, select C315C330J2G5TA or C320C330J2G5TA. Both parts maintain the 200V rating with ±5% tolerance, which is tighter than the original ±10% specification. The C315C330J2G5TA offers a more compact footprint (0.150" x 0.100" body, 0.183" height) compared to the original M15G330K2 (0.150" x 0.130" body, 0.270" height), providing space savings on PCB layouts. The C320C330J2G5TA provides a larger body format (0.200" x 0.125") with 0.290" height for applications where additional thermal mass or mechanical robustness is required.

Voltage-Upgraded Substitutes (250V Rating):

All C315C and C320C series parts with 250V ratings provide enhanced voltage margin over the original 200V specification. These include C315C330FAG5TA, C315C330GAG5TA, C315C330JAG5TA, and C315C330KAG5TA in the compact size, and C320C330FAG5TA, C320C330GAG5TA, C320C330JAG5TA, and C320C330KAG5TA in the larger size. Selection among these should be based on tolerance requirements: ±1% (FAG5TA), ±2% (GAG5TA), ±5% (JAG5TA), or ±10% (KAG5TA).

Compliance Advantage:

All KEMET substitutes are ROHS3 compliant, addressing regulatory requirements that the obsolete M15G330K2 does not meet. This compliance status is essential for new designs and products subject to RoHS directives.

Physical Footprint Considerations:

The C315C series maintains approximate dimensional compatibility with the original part while reducing height from 0.270" to 0.183", enabling denser PCB layouts. The C320C series provides larger body dimensions (0.200" x 0.125" vs. 0.150" x 0.130") and increased height (0.290"), suitable for applications requiring enhanced thermal performance or mechanical stability. Lead spacing remains constant at 0.100" (2.54mm) across all substitutes, ensuring PCB hole pattern compatibility.

Frequently Asked Questions (FAQ)

Q: Can C315C330J2G5TA directly replace M15G330K2 in existing PCB designs?

A: Yes, with physical layout verification. Both parts share 0.100" (2.54mm) lead spacing and radial through-hole mounting. The C315C330J2G5TA has a smaller body (0.150" x 0.100" vs. 0.150" x 0.130") and reduced height (0.183" vs. 0.270"), which may require PCB footprint adjustment if the original design has tight component spacing constraints. Electrical specifications are compatible: 33 pF capacitance, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range match exactly.

Q: What is the difference between C315C and C320C series substitutes?

A: The primary difference is physical size. C315C series parts measure 0.150" L x 0.100" W with 0.183" maximum seated height, providing a compact footprint. C320C series parts measure 0.200" L x 0.125" W with 0.290" maximum seated height, offering a larger body format. Both series maintain identical electrical specifications (33 pF, C0G/NP0, -55°C to 125°C) and 0.100" lead spacing. Selection depends on available PCB space and thermal requirements.

Q: Why do substitute parts have higher voltage ratings (250V vs. 200V)?

A: The 250V-rated substitutes provide enhanced voltage margin and design safety. Since all parts maintain identical capacitance, temperature coefficient, and operating temperature range, the higher voltage rating does not affect circuit performance but improves reliability margin. Applications requiring exactly 200V can use C315C330J2G5TA or C320C330J2G5TA, which match the original voltage specification.

Q: Are tolerance differences between ±1%, ±2%, ±5%, and ±10% significant for general-purpose applications?

A: Tolerance selection depends on circuit requirements. The original M15G330K2 specifies ±10% tolerance. Substitutes with tighter tolerances (±1%, ±2%, ±5%) provide improved capacitance accuracy, beneficial for precision timing circuits, filters, or impedance-critical applications. For general-purpose applications where ±10% tolerance is acceptable, C315C330KAG5TA or C320C330KAG5TA provide direct tolerance matching.

Q: Is the M15G330K2 obsolete status a concern for new designs?

A: Yes. The obsolete status indicates the part is no longer manufactured by Cornell Dubilier Electronics. New designs should specify active KEMET substitutes from the GoldMax 300 Comm C0G series (C315C or C320C base part numbers). All active substitutes are ROHS3 compliant and have confirmed long-term availability, supporting production continuity and regulatory compliance.

Q: Can C320C330KAG5TA be used in place of C315C330KAG5TA?

A: Electrically, yes. Both parts are 33 pF, ±10%, 250V, C0G/NP0 ceramic capacitors with identical electrical performance. However, the C320C series has a larger body (0.200" x 0.125" vs. 0.150" x 0.100") and greater height (0.290" vs. 0.183"). Physical substitution requires PCB layout verification to ensure the larger component fits within available space and does not interfere with adjacent components or assembly processes.

Q: What is the significance of the "Low ESL" feature listed for KEMET substitutes?

A: Low ESL (Equivalent Series Inductance) is a performance characteristic of the KEMET GoldMax 300 Comm C0G series. While this feature is not a substitution requirement for the M15G330K2, it indicates improved high-frequency performance. For general-purpose applications, this feature provides additional performance margin without affecting basic electrical compatibility.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in bulk packaging, consistent with the original M15G330K2. Lead spacing (0.100" / 2.54mm) and lead style (straight) are identical across all substitutes, ensuring compatibility with standard through-hole PCB assembly processes.
