HT06CW103KN Equivalent & Substitute Parts

Part Overview

The HT06CW103KN is a 10000 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KEMET. This component is designed for general-purpose applications requiring high-temperature operation across the range of -55°C to 200°C. The part is classified as obsolete, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility while offering active product status and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06CW103KN is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 10000 pF
• Voltage rating: 100V minimum
• Tolerance: ±10% or tighter
• Temperature coefficient: X7R (ensures stable capacitance across temperature range)

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole Radial
• Lead spacing: 0.200" (5.08mm) for PCB hole alignment
• Lead style: Straight

Operational Parameters:

• Operating temperature range must support the application requirements

The substitute part 1C20X7R103K100B meets all electrical and mechanical criteria for direct substitution. However, the operating temperature range differs: the substitute operates from -55°C to 125°C, which is narrower than the original part's -55°C to 200°C range. This difference must be evaluated against actual application requirements.

Engineering Selection Recommendations

Primary Substitute: 1C20X7R103K100B

The 1C20X7R103K100B from Vishay Beyschlag/Draloric/BC Components is the qualified equivalent for the obsolete HT06CW103KN. This substitute maintains electrical equivalence across all critical parameters: capacitance, voltage rating, tolerance, and temperature coefficient.

Compliance Status:

• The substitute is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements
• Both parts share identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications

Critical Consideration: The operating temperature range of the substitute (-55°C to 125°C) is narrower than the original part (-55°C to 200°C). Selection of this substitute is appropriate only for applications where the maximum operating temperature does not exceed 125°C. For applications requiring operation above 125°C, alternative high-temperature ceramic capacitors must be sourced.

Availability: The substitute part is in active production with 8274 units in stock, ensuring supply continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 1C20X7R103K100B be used as a direct replacement for HT06CW103KN on existing PCBs?

A: Yes, for applications operating at or below 125°C. Both parts have identical lead spacing (0.200"), straight lead style, and radial package configuration. Physical board layout compatibility is confirmed. However, if your application requires operation above 125°C, this substitute is not suitable.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates that the capacitance change over the operating temperature range is limited to ±15% of the nominal value at 25°C. This specification ensures stable capacitance performance across temperature variations, making X7R suitable for general-purpose applications where temperature stability is required.

Q: Why does the substitute have a narrower operating temperature range?

A: The HT06CW103KN is part of KEMET's HTHP LDD Industrial X7R series specifically designed for high-temperature applications up to 200°C. The 1C20X7R103K100B is from Vishay's standard Monolythic series with a maximum rating of 125°C. These represent different product lines with different thermal specifications.

Q: Are there any compliance differences between the original and substitute?

A: Both parts share the same ECCN and HTSUS classifications. The substitute is RoHS3 Compliant and REACH Unaffected, meeting current environmental regulations. The original part's compliance status is not specified in the provided data.

Q: What should I verify before implementing this substitute?

A: Confirm that your application's maximum operating temperature does not exceed 125°C. Verify that the circuit design does not depend on the extended high-temperature capability of the original part. Confirm PCB layout compatibility with the 0.200" lead spacing.

Q: Is the ±10% tolerance suitable for my application?

A: The tolerance specification indicates that the actual capacitance value will fall within ±10% of the nominal 10000 pF value (9000 pF to 11000 pF). If your circuit requires tighter tolerance, consult the manufacturer for alternative specifications.
