Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06AB224JC is determined by the following criteria:

Mandatory Match Parameters:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±5% or tighter
• Temperature Coefficient: X7R (ensures equivalent thermal performance)
• Mounting Type: Through Hole Radial (PCB assembly compatibility)
• Lead Spacing: 0.200" (5.08mm) (footprint compatibility)
• Package / Case: Radial (mechanical and electrical interface)

Allowable Variation Parameters:

• Voltage Rating: Substitute must be rated equal to or greater than 25V
• Operating Temperature Range: Substitute may differ; minimum requirement is coverage of application-specific temperature needs
• Physical Dimensions: Minor variations in height and seated height are acceptable provided lead spacing and radial configuration remain unchanged
• Product Status: Active or obsolete status does not affect electrical substitutability

The SR301C224JAR from KYOCERA AVX meets all mandatory match parameters and exceeds the voltage rating requirement, qualifying it as a direct electrical and mechanical substitute.

Engineering Selection Recommendations

SR301C224JAR as Primary Substitute:

The SR301C224JAR is electrically and mechanically compatible with the HT06AB224JC for direct substitution in general-purpose applications. The substitute part meets all mandatory electrical parameters: identical capacitance (0.22 µF), tolerance (±5%), temperature coefficient (X7R), and lead spacing (0.200").

The SR301C224JAR provides a higher voltage rating (100V versus 25V), which is advantageous for circuit reliability and does not create incompatibility. The substitute operates across -55°C to 125°C, which covers the lower portion of the original part's temperature range. Applications requiring operation above 125°C must be evaluated against specific circuit requirements.

The SR301C224JAR is manufactured by KYOCERA AVX and maintains active product status, ensuring ongoing availability and supply chain stability. The part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Physical height difference: The SR301C224JAR seated height is 0.360" (9.14mm) compared to the HT06AB224JC at 0.300" (7.62mm). This 0.060" difference must be verified against PCB clearance constraints, particularly in applications with height-restricted enclosures or dense component layouts.

Substitution Conditions:

• Voltage rating of 100V is acceptable for circuits designed for 25V operation
• Operating temperature range of -55°C to 125°C is acceptable for applications not requiring sustained operation above 125°C
• PCB clearance must accommodate the increased seated height of 0.360"
• Lead spacing and radial configuration ensure direct footprint compatibility

Frequently Asked Questions (FAQ)

Q: Can the SR301C224JAR replace the HT06AB224JC in any application?

A: The SR301C224JAR is electrically compatible with the HT06AB224JC for general-purpose applications. Substitution is valid when: (1) the circuit operates at or below 125°C, (2) PCB clearance accommodates the 0.360" seated height, and (3) the higher 100V rating does not conflict with circuit design specifications.

Q: Why is the voltage rating higher on the substitute part?

A: The SR301C224JAR is rated for 100V while the HT06AB224JC is rated for 25V. A higher voltage rating does not create incompatibility; it provides additional safety margin. The substitute part will function correctly in circuits designed for 25V operation.

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

A: X7R indicates that capacitance variation remains within ±15% across the operating temperature range. Both the HT06AB224JC and SR301C224JAR use X7R dielectric, ensuring equivalent thermal stability and predictable performance across temperature extremes.

Q: Does the height difference affect PCB assembly?

A: The SR301C224JAR is 0.060" (1.52mm) taller than the HT06AB224JC when seated. This difference must be verified against PCB layout constraints, including component clearance to adjacent parts, enclosure height limitations, and wave soldering or reflow process parameters.

Q: Are there compliance or regulatory differences between these parts?

A: The SR301C224JAR is ROHS3 compliant and REACH unaffected. The HT06AB224JC specifications do not include explicit compliance documentation. For applications requiring specific regulatory certifications, the SR301C224JAR meets current environmental and safety standards.

Q: Can the SR301C224JAR be used in high-temperature applications above 125°C?

A: The SR301C224JAR is rated for operation only to 125°C maximum. The original HT06AB224JC operates to 200°C. Applications requiring sustained operation above 125°C cannot use the SR301C224JAR as a substitute and require alternative component selection.

Q: Is the ±5% tolerance maintained on the substitute part?

A: Yes. Both the HT06AB224JC and SR301C224JAR maintain ±5% capacitance tolerance, ensuring equivalent precision for circuit design calculations and performance specifications.
