HT06CN393JN Equivalent & Substitute Parts

Part Overview

The HT06CN393JN is a 0.039 µF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 200°C). The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06CN393JN is based on strict electrical and mechanical parameter matching:

Electrical Equivalence Requirements:

• Capacitance value: 0.039 µF (exact match)
• Voltage rating: 100V minimum
• Tolerance: ±5% or tighter
• Temperature coefficient: C0G/NP0 (mandatory for stability)

Mechanical Compatibility Requirements:

• Mounting type: Through-hole radial configuration
• Lead spacing: 0.200" (5.08mm) pitch
• Lead style: Straight or formed leads compatible with standard PCB holes
• Package case: Radial ceramic capacitor

The substitute part C330C393J1G5TA meets all electrical requirements and maintains mechanical compatibility through identical lead spacing and radial through-hole mounting. The primary distinction is the operating temperature range and product status (active vs. obsolete).

Engineering Selection Recommendations

Primary Substitute: C330C393J1G5TA

The C330C393J1G5TA is the direct electrical equivalent of the HT06CN393JN with the following considerations:

1. Electrical Compatibility: All critical electrical parameters match exactly (capacitance, voltage, tolerance, temperature coefficient). The substitute maintains C0G/NP0 stability required for precision applications.

2. Mechanical Compatibility: Lead spacing (0.200" / 5.08mm) and radial through-hole mounting are identical. Formed leads on the substitute are compatible with standard PCB hole patterns.

3. Temperature Range Limitation: The substitute operates to 125°C maximum versus the original 200°C maximum. Applications requiring operation above 125°C cannot use this substitute.

4. Product Status: The substitute is active production, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

5. Compliance: The substitute is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Selection Criteria: Use C330C393J1G5TA for applications operating within -55°C to 125°C. For applications requiring the full -55°C to 200°C range, alternative high-temperature ceramic capacitors with matching electrical specifications must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can C330C393J1G5TA replace HT06CN393JN in all applications?

A: C330C393J1G5TA is electrically and mechanically compatible for applications operating within -55°C to 125°C. Applications requiring operation above 125°C require alternative components.

Q: What is the difference between straight leads and formed leads?

A: Straight leads are pre-cut perpendicular to the capacitor body. Formed leads are pre-bent for insertion into PCB holes. Both are compatible with standard through-hole PCB designs; formed leads may require less manual bending during assembly.

Q: Are the physical dimensions compatible?

A: Lead spacing is identical at 0.200" (5.08mm). Body dimensions differ slightly (HT06CN393JN: 0.300" L x 0.150" W; C330C393J1G5TA: 0.280" L x 0.160" W), but both fit standard radial capacitor footprints. Height differences (0.300" vs. 0.360" seated) are within typical PCB clearance tolerances.

Q: Why is the operating temperature range different?

A: The HT06CN393JN is from the HTHP LDD Industrial series designed for high-temperature applications. The C330C393J1G5TA is from the GoldMax 300 Commercial series optimized for standard commercial temperature ranges. Different design objectives result in different maximum ratings.

Q: Is RoHS compliance required for my application?

A: The substitute C330C393J1G5TA is ROHS3 compliant. If RoHS compliance is mandatory, the substitute meets this requirement. The original part's RoHS status is not specified in available documentation.

Q: Can I use a higher voltage rating capacitor as a substitute?

A: Yes. A capacitor with voltage rating equal to or greater than 100V is acceptable. However, only C330C393J1G5TA at 100V is listed as the direct equivalent. Higher voltage alternatives would require separate evaluation.

Q: What does C0G/NP0 mean for substitution purposes?

A: C0G and NP0 are equivalent designations for temperature coefficient indicating minimal capacitance change across temperature. Both terms refer to the same performance characteristic. Substitutes must use C0G or NP0 to maintain circuit stability.
