HT06CW332JN Equivalent & Substitute Parts

Part Overview

The HT06CW332JN is a 3300 pF ceramic capacitor manufactured by KEMET, rated for 100V with X7R temperature coefficient and radial through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production support and design continuity. The X7R dielectric and high-temperature operating range (-55°C to 200°C) define its primary application domain in industrial and high-temperature environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CW332JN is determined by the following mandatory parameters:

Electrical Compatibility:

• Capacitance value must equal 3300 pF
• Voltage rating must be ≥100V
• Tolerance must be ≤±5%
• Temperature coefficient must be X7R

Mechanical Compatibility:

• Mounting type must be through-hole radial
• Lead spacing must accommodate 0.200" (5.08mm) PCB hole pattern
• Package case must be radial configuration

Environmental Compliance:

• Operating temperature range must support application requirements
• Moisture sensitivity level classification must be compatible with assembly process

The SR207C332JAR from KYOCERA AVX meets all mandatory electrical and mechanical substitution criteria. While the substitute exhibits a higher voltage rating (500V) and different operating temperature maximum (125°C vs. 200°C), these parameters represent acceptable deviations for general-purpose applications where the original 100V specification is not a limiting constraint.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Lead Spacing Incompatibility

The SR207C332JAR substitute exhibits a lead spacing of 0.100" (2.54mm) compared to the original HT06CW332JN specification of 0.200" (5.08mm). This dimensional difference represents a critical mechanical constraint that prevents direct PCB footprint compatibility without design modification. Substitution of this part requires either PCB redesign to accommodate the narrower lead spacing or manual lead bending/spacing adjustment during assembly.

Voltage Rating Elevation

The substitute part's 500V rating exceeds the original 100V specification. This parameter elevation does not compromise circuit functionality in applications where 100V operation is specified, as higher-rated components operate safely at lower voltages. No circuit redesign is required based on this parameter difference.

Operating Temperature Range Limitation

The substitute's maximum operating temperature of 125°C is lower than the original specification of 200°C. Applications requiring sustained operation above 125°C cannot use this substitute without thermal performance verification. For general-purpose applications operating within standard industrial temperature ranges (-55°C to 125°C), this limitation is not restrictive.

Product Status and Compliance

The SR207C332JAR is actively manufactured and ROHS3 compliant, providing supply chain continuity and regulatory compliance advantages over the obsolete HT06CW332JN. Long-term availability and manufacturing consistency favor selection of the active substitute where mechanical constraints can be resolved.

Frequently Asked Questions (FAQ)

Q: Can the SR207C332JAR be used as a direct replacement without PCB modification?

A: No. The lead spacing difference (0.100" vs. 0.200") requires either PCB redesign or manual lead adjustment. Direct socket substitution is not possible without mechanical modification.

Q: Does the higher 500V rating of the substitute create any circuit compatibility issues?

A: No. Higher voltage-rated capacitors operate safely at lower voltages. The 500V rating of the substitute is compatible with 100V circuit applications.

Q: Is the SR207C332JAR suitable for applications requiring 200°C operation?

A: No. The substitute's maximum operating temperature is 125°C. Applications requiring sustained operation above 125°C require alternative parts with higher temperature ratings.

Q: What is the significance of the ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates the substitute meets current environmental and regulatory standards for electronic component manufacturing. This supports long-term supply chain viability and regulatory compliance in modern manufacturing environments.

Q: Are there any electrical performance differences between the two parts?

A: Both parts share identical capacitance (3300 pF), tolerance (±5%), and temperature coefficient (X7R). Electrical performance in circuit operation is equivalent within specified operating parameters.

Q: What inventory considerations apply to this substitution?

A: The SR207C332JAR is actively manufactured with 1116 units in stock, compared to the obsolete HT06CW332JN with 943 units remaining. The substitute provides superior long-term supply availability.
