HT55CN221JC Equivalent & Substitute Parts

Part Overview

The HT55CN221JC is a 220 pF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for high-temperature applications with an operating range of -55°C to 200°C. The part is currently obsolete, making identification of equivalent substitutes necessary for ongoing design support, maintenance, and production continuity. Equivalent parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT55CN221JC is based on strict electrical and mechanical parameter matching. The following parameters must be identical or compatible:

Critical Matching Parameters:

• Capacitance value: 220 pF (exact match required)
• Voltage rating: 100V (minimum; higher ratings acceptable)
• Tolerance: ±5% (exact match required for circuit performance)
• Temperature coefficient: C0G/NP0 (exact match required for stability)
• Mounting type: Through-hole radial configuration
• Lead spacing: 0.200" (5.08mm) for PCB compatibility
• Lead style: Straight leads for standard through-hole insertion

Application-Dependent Parameters:

• Operating temperature range: The main part operates to 200°C. Substitutes with lower maximum operating temperatures may be acceptable depending on actual circuit thermal requirements.

The substitute part 1C20C0G221J100B meets all critical electrical parameters and mechanical dimensions required for direct replacement in standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

The 1C20C0G221J100B from Vishay Beyschlag/Draloric/BC Components is a direct electrical equivalent to the obsolete HT55CN221JC. Both parts share identical capacitance, voltage rating, tolerance, and temperature coefficient specifications. Mechanical compatibility is confirmed through matching lead spacing (0.200" / 5.08mm), lead style (straight), and radial through-hole package configuration.

Product Status Consideration: The substitute part maintains active product status with current manufacturing and availability (1019 pcs in stock), providing supply chain continuity for the obsolete KEMET component.

Temperature Range Consideration: The substitute part operates to 125°C maximum, compared to the original part's 200°C rating. For applications requiring sustained operation above 125°C, the substitute is not suitable. For general-purpose and standard industrial applications operating within the -55°C to 125°C range, the substitute provides full functional equivalence.

Compliance Status: The substitute part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 1C20C0G221J100B be used as a direct replacement for the HT55CN221JC?

A: Yes, for applications operating within -55°C to 125°C. All electrical parameters (capacitance, voltage, tolerance, temperature coefficient) are identical. Physical dimensions and lead spacing are compatible with standard through-hole PCB layouts
