HT06CW104KN Equivalent & Substitute Parts Reference

Part Overview

The HT06CW104KN is a 0.1 µF ±10% 100V ceramic capacitor with X7R temperature coefficient manufactured by KEMET. This radial through-hole component is designed for general-purpose applications in high-temperature environments, with an operating range of -55°C to 200°C. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute components maintain the same capacitance, voltage rating, and mounting type while offering improved availability and compliance status.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	0.1 µF	Must match exactly
Voltage Rating	100V	Minimum requirement; higher ratings acceptable
Tolerance	±10%	Tighter tolerances acceptable
Temperature Coefficient	X7R	Defines temperature stability; C0G/NP0 acceptable as upgrade
Operating Temperature	-55°C ~ 200°C	Application-dependent; lower range acceptable if within circuit requirements
Mounting Type	Through Hole Radial	Must match for PCB compatibility
Lead Spacing	0.200" (5.08mm)	Critical for PCB footprint compatibility
RoHS Status	Non-compliant	Compliance requirement varies by application

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on substitution type and electrical characteristics:

Direct Substitutes (Same Electrical Characteristics):

ARR06D104KGS: Active product with identical capacitance, voltage, and tolerance specifications
C062H104K1R5GA: Active product with identical electrical specifications; features low ESL design

Upgrade Substitutes (Enhanced Specifications):

C330C series parts: Active products with improved tolerance (±1% or ±2% vs. ±10%), C0G/NP0 temperature coefficient (superior stability vs. X7R), and RoHS3 compliance
Available in multiple voltage ratings: 100V, 200V, and 250V
Available in multiple tolerances: ±1%, ±2%, and ±5%

Substitution Logic: All substitute parts maintain the 0.1 µF capacitance value and 0.200" (5.08mm) lead spacing. Direct substitutes preserve the X7R temperature coefficient and ±10% tolerance. Upgrade substitutes offer tighter tolerances and C0G/NP0 temperature coefficient, which provides superior temperature stability and lower capacitance drift. Voltage ratings equal to or exceeding 100V are acceptable. Operating temperature ranges may differ; C0G/NP0 parts operate to -55°C ~ 125°C, which is acceptable for applications not requiring the full 200°C upper limit of the original part.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

ARR06D104KGS is the primary direct substitute for HT06CW104KN. Both parts maintain X7R temperature coefficient, ±10% tolerance, 100V rating, and -55°C to 200°C operating range. ARR06D104KGS is an active product with current manufacturing status and equivalent inventory availability. This part is suitable for applications requiring exact electrical and thermal characteristics of the original component.

C062H104K1R5GA provides an alternative direct substitute with identical electrical specifications and the additional benefit of RoHS3 compliance. This part includes low ESL design features and is actively manufactured. Selection of C062H104K1R5GA is appropriate for applications subject to RoHS regulations or where low ESL characteristics provide circuit performance benefits.

For Upgraded Performance:

The C330C series represents upgrade substitutes with enhanced specifications. These parts are all RoHS3 compliant and actively produced. Selection criteria depend on application requirements:

Tolerance Upgrade: C330C parts with ±1%, ±2%, or ±5% tolerance provide tighter capacitance control compared to the original ±10% specification. Applications requiring precise capacitance values benefit from these options.
Voltage Upgrade: C330C parts rated at 200V or 250V provide increased voltage margin beyond the original 100V specification. Applications with voltage transients or design margin requirements benefit from higher-rated parts.
Temperature Coefficient Upgrade: C330C parts with C0G/NP0 temperature coefficient provide superior temperature stability compared to X7R. However, operating temperature range is limited to -55°C to 125°C. This substitution is valid only for applications not requiring operation above 125°C.

Compliance Considerations:

The original HT06CW104KN is RoHS non-compliant. For applications subject to RoHS regulations, C062H104K1R5GA or any C330C variant must be selected. All C330C series parts are RoHS3 compliant and REACH unaffected.

Product Status:

ARR06D104KGS and all C330C variants are active products with current manufacturing and distribution. These parts are suitable for new designs and ongoing production. The original HT06CW104KN is obsolete and should not be specified for new applications.

Frequently Asked Questions (FAQ)

Q: Can ARR06D104KGS directly replace HT06CW104KN without circuit modification?

A: Yes. ARR06D104KGS maintains identical capacitance (0.1 µF), voltage rating (100V), tolerance (±10%), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C). The 0.200" lead spacing and through-hole radial package are identical. No circuit modification is required.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R temperature coefficient specifies capacitance change of ±15% across the -55°C to 200°C operating range. C0G/NP0 temperature coefficient specifies capacitance change of 0±30 ppm/°C across the -55°C to 125°C operating range. C0G/NP0 provides superior temperature stability but operates only to 125°C maximum. For applications not exceeding 125°C, C0G/NP0 parts provide tighter capacitance control.

Q: Can C330C parts rated at 200V or 250V be used in a 100V circuit?

A: Yes. Voltage rating specifies the maximum voltage the capacitor can withstand. A 200V or 250V rated capacitor operates safely at 100V. Higher voltage ratings provide increased design margin and are acceptable substitutes.

Q: What does RoHS3 compliance mean for this capacitor?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. RoHS3 compliant parts are required for applications subject to European Union regulations or customer specifications requiring RoHS compliance.

Q: Are the physical dimensions of C330C parts compatible with the original HT06CW104KN footprint?

A: Lead spacing is identical at 0.200" (5.08mm) for all parts listed. However, body dimensions differ. HT06CW104KN has dimensions of 0.300" L x 0.150" W. C330C parts have dimensions of 0.280" L x 0.160" W. Height-seated dimensions also vary. Verify PCB layout clearances before substitution. Lead spacing compatibility ensures electrical connection; physical clearance must be confirmed for mechanical fit.

Q: Which substitute part should be selected for a new design?

A: For new designs, select from active products: ARR06D104KGS, C062H104K1R5GA, or C330C series. If RoHS compliance is required, select C062H104K1R5GA or any C330C variant. If operating temperature exceeds 125°C, select ARR06D104KGS or C062H104K1R5GA to maintain the full -55°C to 200°C range. If tighter tolerance or higher voltage rating is beneficial, select the appropriate C330C variant.
