HT06CN682KC Equivalent & Substitute Parts

Part Overview

The HT06CN682KC is a 6800 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for high-temperature applications with an operating range of -55°C to 200°C. The part is classified as obsolete, making identification of equivalent substitutes necessary for ongoing design support and procurement continuity. The HT06CN682KC belongs to the HTHP LDD Industrial C0G series and is suitable for general-purpose applications requiring stable capacitance across temperature extremes.

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CN682KC is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 6800 pF (exact match required)
• Voltage rating: 100V (minimum requirement)
• Temperature coefficient: C0G/NP0 (mandatory for stability)
• Mounting type: Through Hole Radial (physical compatibility)
• Lead spacing: 0.200" (5.08mm) (PCB footprint compatibility)

Secondary Compatibility Factors:

• Tolerance: ±10% or tighter acceptable
• Operating temperature range: Must support application requirements
• Package dimensions: Physical fit within board constraints

The substitute part C330C682J1G5TA meets all primary matching criteria. It maintains identical capacitance, voltage rating, temperature coefficient, mounting configuration, and lead spacing. The substitute offers improved tolerance (±5% versus ±10%) and is currently in active production status, providing superior long-term availability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The C330C682J1G5TA serves as a direct functional substitute for the HT06CN682KC based on electrical and mechanical compatibility. Both components share identical capacitance, voltage rating, temperature coefficient, and lead spacing specifications. The substitute part is manufactured by the same supplier (KEMET) and maintains through-hole radial configuration for direct PCB footprint compatibility.

The C330C682J1G5TA offers the following advantages: active production status ensures long-term availability, improved tolerance specification (±5% versus ±10%) provides tighter capacitance control, ROHS3 compliance and REACH unaffected status satisfy modern regulatory requirements, and low ESL characteristics support high-frequency performance.

A design consideration exists regarding operating temperature range. The HT06CN682KC operates to 200°C, while the C330C682J1G5TA operates to 125°C. Applications requiring sustained operation above 125°C require thermal analysis to confirm the substitute part's suitability. For applications operating within the -55°C to 125°C range, the substitute part is fully compatible without thermal derating.

Frequently Asked Questions (FAQ)

Q: Can C330C682J1G5TA directly replace HT06CN682KC on existing PCBs?

A: Yes, for applications operating within -55°C to 125°C. Both parts share identical lead spacing (0.200"), radial package configuration, and through-hole mounting. The formed leads on the substitute part accommodate standard PCB hole patterns. Applications requiring operation above 125°C require thermal verification before substitution.

Q: What is the tolerance difference between these parts?

A: The HT06CN682KC specifies ±10% tolerance, while the C330C682J1G5TA specifies ±5% tolerance. The substitute part provides tighter capacitance control, which is beneficial for precision applications. Both tolerances are acceptable for general-purpose circuits where the original ±10% specification was adequate.

Q: Are there compliance differences between the main part and substitute?

A: The C330C682J1G5TA carries ROHS3 compliance and REACH unaffected status. The HT06CN682KC specifications do not include these compliance statements. For applications subject to ROHS3 or REACH requirements, the substitute part satisfies regulatory obligations.

Q: What does "Low ESL" mean for the substitute part?

A: Equivalent Series Inductance (ESL) is a parasitic characteristic of capacitors. The GoldMax 300 series (C330C682J1G5TA) is designed with low ESL characteristics, which improves high-frequency performance and reduces impedance at elevated frequencies. This is a performance enhancement compared to the main part specification.

Q: Why is the main part obsolete?

A: The HT06CN682KC belongs to the HTHP LDD Industrial series, which has been superseded by newer product lines. KEMET's GoldMax 300 series represents current production technology. Obsolescence does not indicate performance deficiency but reflects manufacturer product lifecycle management and transition to improved designs.

Q: Can the substitute part be used in high-temperature applications above 125°C?

A: The C330C682J1G5TA is rated to 125°C maximum. Applications requiring sustained operation above 125°C must use components rated for those temperatures. The original HT06CN682KC rated to 200°C may be necessary for extreme high-temperature designs, though procurement of obsolete parts presents supply chain challenges.
