HT06CW474KN Equivalent & Substitute Parts

Part Overview

The HT06CW474KN is a 0.47 µF 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 functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	0.47 µF	Must match exactly
Voltage Rating	100V	Must match or exceed
Tolerance	±10%	Must match or be tighter
Temperature Coefficient	X7R	Must match for temperature stability
Operating Temperature Range	-55°C ~ 200°C	Substitute must support minimum range
Mounting Type	Through Hole	Must match for PCB compatibility
Package Type	Radial	Must match for mechanical fit
Lead Spacing	0.200" (5.08mm)	Must match for board layout

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CW474KN is determined by strict alignment with the following electrical and mechanical parameters:

Electrical Criteria:

Capacitance value: 0.47 µF (exact match required)
Voltage rating: 100V minimum
Tolerance: ±10% or tighter
Temperature coefficient: X7R (mandatory for temperature stability characteristics)

Mechanical Criteria:

Mounting type: Through Hole
Package configuration: Radial
Lead spacing: 0.200" (5.08mm)
Lead style: Straight

Environmental Criteria:

Operating temperature range must support at least -55°C to 125°C minimum; higher temperature capability is acceptable

The identified substitute SR301C474KAR meets all mandatory electrical and mechanical parameters. Substitution is valid where the operating temperature requirement does not exceed 125°C, as this represents the upper limit of the substitute's rated range compared to the original part's 200°C capability.

*Partial Match: SR301C474KAR supports -55°C to 125°C. Applications requiring operation above 125°C require alternative solutions.

**Compatible: Dimensional difference in width (0.150" vs 0.125") is within typical PCB layout tolerances for radial through-hole components with 0.200" lead spacing.

Engineering Selection Recommendations

For applications operating within -55°C to 125°C: SR301C474KAR is a direct functional substitute. The part is currently in active production status with 1469 units in stock, ensuring supply continuity. KYOCERA AVX certification includes ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

For applications requiring operation above 125°C: The SR301C474KAR does not meet the extended temperature requirement of the original HT06CW474KN (-55°C to 200°C). Alternative high-temperature ceramic capacitors with identical electrical specifications must be evaluated from manufacturers specializing in extended-temperature components.

Supply and Obsolescence Considerations: The HT06CW474KN is obsolete with limited remaining inventory (1060 units). The SR301C474KAR provides immediate supply security with active production status and higher current inventory levels (1469 units).

Frequently Asked Questions (FAQ)

Q: Can SR301C474KAR be used as a direct replacement for HT06CW474KN in all applications?

A: SR301C474KAR is a direct electrical and mechanical substitute for applications with operating temperatures not exceeding 125°C. The original part supports operation to 200°C; applications requiring this extended temperature range require alternative component selection.

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

A: X7R designates a ceramic capacitor with a temperature coefficient of ±15% across the operating range. This specification ensures predictable capacitance stability across temperature variations. Both parts carry identical X7R ratings, maintaining equivalent performance characteristics.

Q: Are there dimensional compatibility concerns with the width difference (0.150" vs 0.125")?

A: No. The width difference is within standard tolerances for radial through-hole capacitors. Both parts maintain identical lead spacing (0.200") and length (0.300"), ensuring PCB footprint compatibility without layout modifications.

Q: What compliance certifications apply to the substitute part?

A: SR301C474KAR carries ROHS3 compliance and REACH unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications.

Q: Is the ±10% tolerance specification critical for substitution?

A: Yes. Tolerance directly affects circuit performance in precision applications. SR301C474KAR matches the ±10% specification exactly. Substitutes with looser tolerances (e.g., ±20%) are not equivalent.

Q: What inventory considerations should guide component selection?

A: The HT06CW474KN is obsolete with 1060 units remaining. SR301C474KAR is in active production with 1469 units currently available, providing superior supply security for ongoing production and future requirements.
