HT06CW105JN Equivalent & Substitute Parts

Part Overview

The HT06CW105JN is a 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 from -55°C to 200°C. The part is classified as obsolete, making identification of functionally equivalent substitutes necessary for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CW105JN is determined by the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 1 µF
• Tolerance: ±5%
• Voltage Rating: 100V (minimum)
• Temperature Coefficient: X7R

Mechanical Parameters (Required for Board Compatibility):

• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)
• Lead Style: Straight

The SR401C105JARTR1 manufactured by KYOCERA AVX meets all electrical requirements. Physical dimensions differ (length and height), but lead spacing and mounting configuration remain compatible with the original design footprint.

Engineering Selection Recommendations

SR401C105JARTR1 Substitution Basis:

The SR401C105JARTR1 is a direct functional substitute for the HT06CW105JN based on matching electrical specifications (1 µF, ±5%, 100V, X7R) and compatible mechanical configuration (through-hole radial with 0.200" lead spacing).

Critical Consideration:

The operating temperature range differs. The HT06CW105JN operates to 200°C, while the SR401C105JARTR1 operates to 125°C. Applications requiring sustained operation above 125°C cannot use this substitute without thermal analysis and design verification.

Compliance Advantage:

The SR401C105JARTR1 carries active product status and ROHS3 compliance certification, providing supply chain continuity and regulatory alignment for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can SR401C105JARTR1 replace HT06CW105JN in all applications?

A: Electrical and mechanical compatibility is confirmed for standard operating conditions. However, applications requiring operation above 125°C must be evaluated separately, as the substitute has a maximum operating temperature of 125°C versus the original 200°C specification.

Q: Are the physical dimensions compatible with the PCB footprint?

A: Yes. Both components use identical lead spacing (0.200" / 5.08mm) and straight lead style. The SR401C105JARTR1 has slightly larger body dimensions (0.400" L vs. 0.300" L), but this does not affect electrical connection or standard PCB mounting patterns designed for radial through-hole components.

Q: What is the difference in packaging between these parts?

A: The HT06CW105JN is supplied in standard packaging. The SR401C105JARTR1 is supplied in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly. Both are through-hole radial components with identical lead configurations.

Q: Does the SR401C105JARTR1 meet current regulatory requirements?

A: Yes. The SR401C105JARTR1 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Are there any electrical performance differences between these capacitors?

A: Both components share identical electrical specifications: 1 µF capacitance, ±5% tolerance, 100V voltage rating, and X7R temperature coefficient. Performance in general-purpose applications is equivalent.
