HT55CN101JC Equivalent & Substitute Parts

Part Overview

The HT55CN101JC is a 100 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring high-temperature stability across the -55°C to 200°C operating range. The part is classified as obsolete, making identification of equivalent substitutes necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55CN101JC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 100 pF
• Tolerance: ±5%
• Voltage Rating: 100V
• Temperature Coefficient: C0G/NP0
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)

The substitute part 1C20C0G101J100B meets all mandatory electrical and mechanical parameters. Physical dimensions show minor variations in body width and seated height, which remain within acceptable through-hole PCB assembly tolerances. The substitute maintains identical lead spacing, ensuring direct PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 1C20C0G101J100B from Vishay Beyschlag/Draloric/BC Components is a direct electrical equivalent to the obsolete HT55CN101JC. Both components share identical capacitance, tolerance, voltage rating, temperature coefficient, and lead spacing specifications.

Compatibility Considerations:

The substitute part exhibits a slightly larger body width (0.125" versus 0.100") and greater seated height (0.250" versus 0.200"). These dimensional differences are within standard through-hole component tolerances and do not affect PCB footprint compatibility, as lead spacing remains constant at 0.200" (5.08mm).

Operating Temperature Limitation:

The substitute part operates across -55°C to 125°C, compared to the original part's -55°C to 200°C range. Applications requiring operation above 125°C cannot use this substitute without thermal performance verification.

Product Status and Compliance:

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

Frequently Asked Questions (FAQ)

Q: Can the 1C20C0G101J100B be used as a direct replacement for HT55CN101JC in existing PCB designs?

A: Yes, for applications operating within the -55°C to 125°C temperature range. The identical lead spacing (0.200" / 5.08mm) and matching electrical specifications ensure PCB footprint compatibility. The slightly larger body dimensions do not affect through-hole assembly.

Q: What is the primary limitation of using the Vishay substitute?

A: The operating temperature range is limited to -55°C to 125°C, compared to the original KEMET part's -55°C to 200°C range. Applications requiring sustained operation above 125°C require alternative solutions.

Q: Are the physical dimension differences significant for PCB layout?

A: No. The critical parameter for through-hole PCB compatibility is lead spacing, which is identical at 0.200" (5.08mm). Body width and seated height variations are within standard component tolerances and do not impact board assembly or spacing requirements.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The 1C20C0G101J100B carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: What is the inventory status of the substitute part?

A: The 1C20C0G101J100B is in active production with 1100 pieces available in new original stock, providing reliable supply chain access compared to the obsolete HT55CN101JC.
