Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT55CN102JC is based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value must be 1000 pF
• Temperature coefficient must be C0G or NP0
• Tolerance must be ±5%
• Voltage rating must be equal to or greater than 100V
• Mounting type must be through-hole radial configuration

Mechanical Compatibility Criteria:

• Lead spacing must be 0.200" (5.08mm)
• Package type must be radial
• Lead style must accommodate standard PCB through-hole mounting

The substitute part C330C102JDG5TA meets all electrical requirements with identical capacitance, tolerance, and temperature coefficient. The voltage rating of 1000V exceeds the original 100V specification, providing additional design margin. Lead spacing remains consistent at 0.200" (5.08mm), ensuring mechanical compatibility with existing PCB layouts.

Engineering Selection Recommendations

The C330C102JDG5TA serves as a direct electrical substitute for the HT55CN102JC with the following considerations:

Voltage Rating: The substitute part is rated at 1000V, which exceeds the original 100V specification. This higher voltage rating is compatible with applications designed for 100V operation and provides additional safety margin in the circuit design.

Temperature Range: The substitute part operates from -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 analysis.

Product Status: The substitute part is classified as active, ensuring continued availability and manufacturing support. The original part is obsolete, making the substitute the appropriate selection for new procurement.

Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Physical Dimensions: The substitute part has larger overall dimensions (0.300" L x 0.200" W versus 0.200" L x 0.100" W) but maintains identical lead spacing of 0.200" (5.08mm), allowing direct PCB mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the C330C102JDG5TA replace the HT55CN102JC in all applications?

A: The C330C102JDG5TA is electrically compatible for applications operating at or below 125°C. Applications requiring operation above 125°C require alternative solutions, as the substitute part's maximum operating temperature is 125°C compared to the original part's 200°C rating.

Q: What is the impact of the higher voltage rating on circuit performance?

A: The 1000V rating of the substitute part is compatible with 100V circuit designs. Higher voltage-rated capacitors do not negatively affect circuit operation at lower voltages; they simply provide additional design margin and safety factor.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: The lead spacing of 0.200" (5.08mm) is identical between both parts, ensuring direct compatibility with existing through-hole PCB layouts. The substitute part has larger overall body dimensions but will fit standard radial capacitor footprints designed for 0.200" lead spacing.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations refer to the same temperature coefficient specification. Both terms indicate negligible capacitance change across the operating temperature range. The substitute part uses this identical specification, ensuring stable capacitance performance.

Q: Why is the substitute part larger than the original?

A: The larger physical dimensions of the C330C102JDG5TA result from its higher voltage rating (1000V versus 100V). Higher voltage ratings require increased dielectric thickness and physical spacing between conductors, resulting in larger component size.

Q: Is the substitute part RoHS compliant?

A: Yes, the C330C102JDG5TA is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
