HT06CW474JC Equivalent & Substitute Parts

Part Overview

The HT06CW474JC is a 0.47 µF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring high-temperature operation across -55°C to 200°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical equivalence in capacitance, voltage rating, and temperature coefficient while accommodating mechanical and packaging variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CW474JC is determined by strict electrical and mechanical parameter matching:

Electrical Equivalence Requirements:

• Capacitance value: 0.47 µF (exact match required)
• Voltage rating: 100V minimum (equal or higher acceptable)
• Temperature coefficient: X7R (required for temperature stability characteristics)

Mechanical Compatibility Requirements:

• Mounting type: Through-hole radial configuration
• Lead spacing: 0.200" (5.08mm) pitch for PCB footprint alignment
• Lead style: Straight leads for standard insertion

Tolerance Considerations: The original part specifies ±5% tolerance. Substitute parts with ±10% tolerance remain functionally equivalent in general-purpose applications where the circuit design accommodates the wider tolerance band.

Operating Temperature Range: The original part operates -55°C to 200°C. Substitutes with narrower ranges (-55°C to 125°C) are acceptable for applications not requiring the full upper temperature capability.

Engineering Selection Recommendations

Primary Substitute: SR301C474KAR (KYOCERA AVX)

The SR301C474KAR is the qualified equivalent for HT06CW474JC replacement based on the following engineering criteria:

1. Electrical Equivalence: Identical capacitance (0.47 µF), voltage rating (100V), and temperature coefficient (X7R) ensure direct functional replacement in circuit applications.

2. Mechanical Compatibility: Matching through-hole radial configuration with 0.200" lead spacing permits direct PCB footprint substitution without layout modifications.

3. Product Status: SR301C474KAR is active production status, ensuring long-term availability and supply chain continuity compared to the obsolete HT06CW474JC.

4. Compliance Standards: SR301C474KAR carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production.

5. Tolerance Accommodation: The ±10% tolerance of SR301C474KAR is acceptable in general-purpose applications where circuit design margins accommodate the wider tolerance band relative to the original ±5% specification.

Temperature Range Consideration: The SR301C474KAR operating range (-55°C to 125°C) is narrower than the original part (-55°C to 200°C). This substitute is suitable for applications operating within the -55°C to 125°C window. Applications requiring operation above 125°C require evaluation of alternative substitutes with extended upper temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can SR301C474KAR directly replace HT06CW474JC without PCB modifications?

A: Yes. Both parts share identical lead spacing (0.200"), radial through-hole configuration, and straight lead style. Direct footprint substitution is possible without PCB layout changes.

Q: Does the ±10% tolerance of SR301C474KAR affect circuit performance compared to the ±5% original?

A: Tolerance impact depends on circuit design margins. In general-purpose applications, ±10% tolerance is functionally equivalent. Critical circuits with tight tolerance requirements must be evaluated individually against circuit specifications.

Q: What is the temperature operating range limitation of SR301C474KAR?

A: SR301C474KAR operates -55°C to 125°C, compared to HT06CW474JC at -55°C to 200°C. The substitute is suitable for applications within this narrower range. Applications requiring sustained operation above 125°C require alternative parts with extended upper temperature ratings.

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

A: SR301C474KAR is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original HT06CW474JC compliance status is not specified in available documentation. The substitute meets modern manufacturing and environmental requirements.

Q: What is the inventory status for substitution?

A: HT06CW474JC has 789 pieces in stock (obsolete status). SR301C474KAR has 1469 pieces in stock with active production status, providing superior long-term availability for ongoing requirements.

Q: Can SR301C474KAR be used in high-temperature applications above 125°C?

A: No. SR301C474KAR maximum operating temperature is 125°C. Applications requiring sustained operation above 125°C require alternative substitutes with extended temperature ratings or the original HT06CW474JC if available inventory permits.
