HT06CW105JC Equivalent & Substitute Parts

Part Overview

The HT06CW105JC is a 1 µF, 100V ceramic capacitor manufactured by KEMET, featuring an X7R temperature coefficient and radial through-hole mounting. This component is classified as Obsolete and is designed for general-purpose applications requiring high-temperature operation across the range of -55°C to 200°C.

Due to its obsolete product status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and temperature coefficient specifications while accommodating potential differences in physical dimensions and packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HT06CW105JC are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Equivalence Requirements:

• Capacitance value: 1 µF (exact match)
• Voltage rating: 100V (exact match or higher)
• Tolerance: ±5% (exact match)
• Temperature coefficient: X7R (exact match)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match)
• Package style: Radial (exact match)
• Lead spacing: 0.200" (5.08mm) (exact match)
• Lead style: Straight (exact match)

Compliance and Availability:

• Product status consideration for long-term supply chain reliability
• RoHS and REACH compliance status for regulatory adherence

The SR401C105JARTR1 manufactured by KYOCERA AVX meets all critical electrical parameters and mechanical mounting specifications. Physical dimensions differ in length and height, which may require PCB layout verification but does not affect electrical functionality or lead-to-lead spacing compatibility.

Engineering Selection Recommendations

SR401C105JARTR1 as Primary Substitute:

The SR401C105JARTR1 is the qualified substitute for the obsolete HT06CW105JC based on the following engineering criteria:

1. Electrical Equivalence: All critical electrical parameters match exactly—capacitance (1 µF), voltage rating (100V), tolerance (±5%), and temperature coefficient (X7R).

2. Mechanical Compatibility: Lead spacing (0.200" / 5.08mm), lead style (straight), mounting type (through-hole), and package style (radial) are identical, ensuring direct PCB footprint compatibility.

3. Product Status: The SR401C105JARTR1 carries Active product status, providing long-term supply chain availability and manufacturing continuity compared to the Obsolete HT06CW105JC.

4. Regulatory Compliance: The SR401C105JARTR1 is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

5. Physical Dimension Consideration: The SR401C105JARTR1 exhibits larger physical dimensions (0.400" L × 0.460" H versus 0.300" L × 0.300" H). PCB layout verification is required to confirm adequate clearance in the target application. The increased size does not affect electrical performance or lead spacing.

6. Operating Temperature Range: The SR401C105JARTR1 operates across -55°C to 125°C, which is narrower than the HT06CW105JC range of -55°C to 200°C. Applications requiring sustained operation above 125°C require alternative evaluation.

Frequently Asked Questions (FAQ)

Q: Can the SR401C105JARTR1 be used as a direct replacement for the HT06CW105JC on existing PCBs?

A: The SR401C105JARTR1 is electrically equivalent and maintains identical lead spacing (0.200" / 5.08mm), enabling direct PCB footprint compatibility. However, the substitute part is physically larger (0.400" L × 0.460" H versus 0.300" L × 0.300" H). PCB layout review is necessary to confirm adequate clearance around the component location. If space constraints exist, alternative substitutes must be evaluated.

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

A: The X7R temperature coefficient indicates that the capacitor maintains stable capacitance across a wide temperature range with minimal variation. Both the HT06CW105JC and SR401C105JARTR1 feature X7R characteristics, ensuring equivalent performance in temperature-sensitive applications. X7R is a standard specification for general-purpose ceramic capacitors.

Q: Why does the SR401C105JARTR1 have a narrower operating temperature range (-55°C to 125°C) compared to the HT06CW105JC (-55°C to 200°C)?

A: The operating temperature range reflects the maximum continuous operating temperature specification for each component design. The HT06CW105JC is rated for high-temperature operation up to 200°C, while the SR401C105JARTR1 is rated to 125°C. For applications requiring sustained operation above 125°C, the SR401C105JARTR1 is not suitable, and alternative high-temperature-rated substitutes must be sourced.

Q: What is the difference between bulk packaging and Tape & Reel (TR) packaging?

A: The HT06CW105JC is supplied in bulk packaging format, while the SR401C105JARTR1 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides better component protection during handling and storage. Bulk packaging is typically used for manual assembly or smaller production volumes. The packaging format does not affect component electrical or mechanical performance.

Q: Are there any compliance or certification differences between these parts?

A: The SR401C105JARTR1 is explicitly RoHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic component procurement in regulated markets. The HT06CW105JC, being obsolete, may not carry current compliance certifications. For applications subject to RoHS or REACH regulations, the SR401C105JARTR1 is the appropriate choice.

Q: Can the SR401C105JARTR1 be used in applications where the HT06CW105JC was originally specified?

A: The SR401C105JARTR1 is suitable for applications where the HT06CW105JC was originally specified, provided that: (1) the operating temperature does not exceed 125°C, (2) PCB layout accommodates the larger physical dimensions, and (3) regulatory compliance with RoHS3 and REACH is required or acceptable. If any of these conditions are not met, alternative substitutes must be evaluated.
