HT06CW224JN Equivalent & Substitute Parts Reference

Part Overview

The HT06CW224JN is a 0.22 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 stable capacitance across a wide temperature range (-55°C to 200°C). The part is classified as obsolete, making identification of functionally equivalent substitutes necessary for ongoing design support and procurement continuity. The high-temperature operating range and industrial-grade specifications position this component for demanding applications in industrial and automotive environments.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	0.22 µF	Critical - must match exactly
Voltage Rating	100V	Critical - must match or exceed
Temperature Coefficient	X7R	Critical - determines capacitance stability
Tolerance	±5%	Critical - defines acceptable capacitance variation
Mounting Type	Through Hole Radial	Critical - determines PCB compatibility
Lead Spacing	0.200" (5.08mm)	Critical - PCB footprint requirement
Package Dimensions	0.300" L x 0.150" W (7.62mm x 3.81mm)	Important - physical space constraints
Operating Temperature Range	-55°C ~ 200°C	Important - application environment compatibility

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CW224JN is determined by strict alignment with the following electrical and mechanical parameters:

Mandatory Matching Parameters:

Capacitance value: 0.22 µF
Voltage rating: 100V (minimum)
Temperature coefficient: X7R
Tolerance: ±5%
Mounting configuration: Through-hole radial
Lead spacing: 0.200" (5.08mm)
Package footprint: 0.300" L x 0.150" W

Acceptable Variation Parameters:

Operating temperature range: Substitute must support minimum -55°C to 125°C; higher upper limits are acceptable
Physical height: Seated height up to 0.360" is acceptable within standard radial package constraints
Product status: Active or obsolete status does not affect electrical equivalence
Packaging format: Bulk or tape/reel packaging does not affect component function

The SR301C224JAR from KYOCERA AVX meets all mandatory parameters and qualifies as a direct electrical and mechanical substitute.

Engineering Selection Recommendations

SR301C224JAR as Direct Substitute:

The SR301C224JAR qualifies as a direct electrical and mechanical substitute for the HT06CW224JN based on identical capacitance, voltage rating, temperature coefficient, tolerance, and physical footprint specifications. Both components are radial through-hole packages with 0.200" lead spacing and matching body dimensions.

Operational Considerations:

The SR301C224JAR operates across -55°C to 125°C, which represents a narrower upper temperature limit compared to the HT06CW224JN (-55°C to 200°C). Applications requiring sustained operation above 125°C must evaluate whether the substitute's temperature range is sufficient for the intended use case.

Compliance Status:

The SR301C224JAR carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components. The HT06CW224JN's compliance status is not specified in the provided data.

Availability:

The SR301C224JAR is classified as active production status with 744 units in stock, providing supply continuity for the obsolete HT06CW224JN (807 units currently available).

Frequently Asked Questions (FAQ)

Q: Can SR301C224JAR be used as a direct replacement for HT06CW224JN in existing designs?

A: Yes, the SR301C224JAR is electrically and mechanically equivalent. Both components share identical capacitance (0.22 µF), voltage rating (100V), temperature coefficient (X7R), tolerance (±5%), and physical footprint (0.300" x 0.150" with 0.200" lead spacing). No PCB modifications are required.

Q: What is the difference in operating temperature range between these parts?

A: The HT06CW224JN operates from -55°C to 200°C, while the SR301C224JAR operates from -55°C to 125°C. The substitute has a lower maximum operating temperature. Designs operating above 125°C must confirm the substitute is suitable for the application environment.

Q: Are the physical dimensions compatible?

A: Yes. Both components have identical body dimensions (0.300" L x 0.150" W / 7.62mm x 3.81mm) and lead spacing (0.200" / 5.08mm). The SR301C224JAR seated height is 0.360" compared to 0.300" for the HT06CW224JN, which remains within acceptable radial package tolerances and does not affect PCB compatibility.

Q: Does the substitute meet modern compliance standards?

A: The SR301C224JAR is ROHS3 compliant and REACH unaffected. The HT06CW224JN compliance status is not specified in available documentation.

Q: Why is the HT06CW224JN classified as obsolete?

A: Obsolescence status indicates the part is no longer in active production by KEMET. The SR301C224JAR, classified as active production, provides ongoing supply availability for equivalent functionality.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Only if the application maximum operating temperature does not exceed 125°C. Applications requiring sustained operation above 125°C must use the HT06CW224JN or identify alternative components rated for higher temperatures.
