HT06DW124KN Equivalent & Substitute Parts

Part Overview

The HT06DW124KN is a 0.12 µF ceramic capacitor rated at 200V with X7R temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring high-temperature operation from -55°C to 200°C. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT06DW124KN is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.12 µF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or greater than 200V
• Operating Temperature Range: May be equal to or narrower than -55°C ~ 200°C
• Physical dimensions: May vary within radial package constraints
• Product Status: Active parts preferred over obsolete

The substitute part C330C124KCR5TA meets all mandatory matching parameters while providing a higher voltage rating (500V) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The C330C124KCR5TA is a direct functional substitute for the HT06DW124KN based on the following engineering criteria:

Electrical Compatibility: Both parts share identical capacitance (0.12 µF), tolerance (±10%), and temperature coefficient (X7R). The substitute's 500V rating exceeds the original 200V requirement, providing additional voltage margin in the application circuit.

Mechanical Compatibility: Both components feature identical lead spacing (0.200" / 5.08mm) and radial through-hole mounting, ensuring direct PCB footprint compatibility. The substitute is slightly larger in body dimensions (0.300" x 0.200" versus 0.300" x 0.150") and seated height (0.360" versus 0.300"), requiring verification of available board space.

Product Status and Compliance: The C330C124KCR5TA is an active product with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment. The original HT06DW124KN is obsolete, making the substitute the appropriate selection for new procurement and system maintenance.

Temperature Consideration: The substitute operates from -55°C to 125°C, which is narrower than the original -55°C to 200°C range. Applications requiring operation above 125°C cannot use this substitute.

Frequently Asked Questions (FAQ)

Q: Can C330C124KCR5TA be used as a direct replacement for HT06DW124KN?

A: Yes, for applications operating at or below 125°C. The substitute matches all critical electrical parameters (capacitance, tolerance, temperature coefficient) and mechanical parameters (lead spacing, mounting type, package type). Physical dimensions are slightly larger; board layout space must be confirmed.

Q: What is the impact of the higher 500V rating on the substitute part?

A: The 500V rating of C330C124KCR5TA exceeds the original 200V requirement. This provides additional voltage margin and does not negatively affect circuit performance. The part will function correctly in circuits designed for 200V operation.

Q: Are there physical installation differences between these parts?

A: Both parts use identical 0.200" lead spacing and radial through-hole mounting. The substitute is slightly larger in body width (0.200" versus 0.150") and seated height (0.360" versus 0.300"). PCB layout must accommodate these dimensions.

Q: What is the temperature operating range limitation?

A: The substitute operates from -55°C to 125°C, compared to the original -55°C to 200°C. If the application requires sustained operation above 125°C, the C330C124KCR5TA is not suitable.

Q: Is the substitute RoHS compliant?

A: Yes, C330C124KCR5TA is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the original HT06DW124KN obsolete?

A: The HT06DW124KN is listed as obsolete by KEMET. The C330C124KCR5TA from the active GoldMax 300 series is the recommended replacement for new designs and ongoing system support.
