HT06CW104JC Equivalent & Substitute Parts

Part Overview

The HT06CW104JC is a 0.1 µF ±5% 100V ceramic capacitor 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 identification of functionally equivalent substitutes necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CW104JC is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Capacitance: 0.1 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 100V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Lead Spacing: 0.200" (5.08mm) (exact match required)
• Lead Style: Straight (exact match required)

Allowable Variations:

• Physical dimensions (length, width, height) may vary within industry standards for radial packages
• Operating temperature range may extend beyond the original specification
• Packaging format (bulk vs. tape & reel) does not affect electrical equivalence
• Product status (active vs. obsolete) does not affect functional equivalence

The substitute part SR891C104JARTR1 meets all critical matching parameters and is therefore classified as a direct electrical and mechanical equivalent.

Engineering Selection Recommendations

SR891C104JARTR1 (KYOCERA AVX SkyCap® SR Series)

This part is the direct equivalent for HT06CW104JC replacement. Selection is based on the following factors:

• Electrical Equivalence: All critical electrical parameters match exactly (capacitance, tolerance, voltage rating, temperature coefficient).
• Mechanical Compatibility: Lead spacing (0.200" / 5.08mm) and lead style (straight) are identical, ensuring direct PCB footprint compatibility.
• Physical Accommodation: The substitute is physically smaller (0.215" L x 0.125" W vs. 0.300" L x 0.150" W), which provides layout flexibility without requiring PCB redesign.
• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain stability.
• Compliance: ROHS3 compliance and REACH unaffected status meet current regulatory requirements.

Operating Temperature Consideration: The substitute operates to 125°C maximum, compared to the original 200°C maximum. Applications requiring sustained operation above 125°C require alternative sourcing.

Frequently Asked Questions (FAQ)

Q: Can SR891C104JARTR1 be used as a direct replacement for HT06CW104JC on existing PCBs?

A: Yes. The parts share identical lead spacing (0.200" / 5.08mm), lead style (straight), and radial package configuration. No PCB modification is required. The substitute is physically smaller, which does not affect electrical performance or mechanical fit.

Q: What is the significance of the operating temperature range difference (-55°C ~ 200°C vs. -55°C ~ 125°C)?

A: The original HT06CW104JC supports continuous operation to 200°C, while SR891C104JARTR1 is rated to 125°C. For applications operating above 125°C, the substitute is not suitable. For applications within -55°C to 125°C, the substitute is fully equivalent.

Q: Does the packaging format difference (bulk vs. tape & reel) affect electrical performance?

A: No. Packaging format affects procurement and assembly logistics only. Electrical and mechanical properties are identical regardless of packaging format.

Q: Are there compliance or certification differences between the two parts?

A: SR891C104JARTR1 carries ROHS3 compliance and REACH unaffected status. The original part's compliance status is not specified in available documentation. For applications requiring specific regulatory compliance, verify against project requirements.

Q: What is the lead spacing tolerance, and does it affect interchangeability?

A: Both parts specify 0.200" (5.08mm) lead spacing. This dimension is the primary determinant of PCB footprint compatibility. Identical lead spacing ensures direct interchangeability without layout modification.

Q: Can the smaller physical dimensions of SR891C104JARTR1 cause any issues?

A: No. Smaller dimensions provide layout flexibility. The critical parameters for PCB mounting (lead spacing and lead style) are identical. Verify clearance to adjacent components if space is constrained.
