Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT55CN561JC is determined by the following critical parameters that must remain constant or be compatible with the original design:

Mandatory Matching Parameters:

• Capacitance value: 560 pF
• Tolerance: ±5%
• Temperature Coefficient: C0G/NP0
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)

Compatible Variation Parameters:

• Voltage Rating: Substitute parts may have equal or higher voltage ratings than the original 100V specification
• Operating Temperature Range: Substitute parts must support the minimum temperature range of the original part or broader
• Physical dimensions: Substitute parts may have different body dimensions provided lead spacing remains constant

The C330C561JAG5TA qualifies as a substitute based on matching capacitance, tolerance, temperature coefficient, mounting type, package configuration, and lead spacing. The substitute part features a higher voltage rating (250V) and different operating temperature range, both of which are compatible with applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The C330C561JAG5TA is an active product from KEMET that provides functional equivalence to the obsolete HT55CN561JC. Both components share identical capacitance, tolerance, temperature coefficient, and lead spacing specifications, ensuring direct mechanical and electrical compatibility in through-hole applications.

The substitute part features a higher voltage rating (250V versus 100V), which provides additional design margin and is compatible with circuits designed for the original 100V specification. The C330C561JAG5TA is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

The operating temperature range of the substitute part (-55°C to 125°C) is narrower than the original part (-55°C to 200°C). Applications requiring operation above 125°C must retain the original HT55CN561JC or identify alternative components with extended high-temperature ratings.

The C330C561JAG5TA is classified as active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete HT55CN561JC.

Frequently Asked Questions (FAQ)

Q: Can the C330C561JAG5TA be used as a direct replacement for the HT55CN561JC in all applications?

A: The C330C561JAG5TA is mechanically and electrically compatible for applications operating within -55°C to 125°C. Applications requiring operation above 125°C must use the original HT55CN561JC or identify components with extended temperature ratings.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The 250V rating on the C330C561JAG5TA provides additional voltage margin compared to the 100V original specification. This higher rating is compatible with 100V circuit designs and does not introduce incompatibility.

Q: Are the physical dimensions of the substitute part identical to the original?

A: The substitute part has different body dimensions (0.280" L x 0.160" W versus 0.200" L x 0.100" W) but maintains the same lead spacing of 0.200" (5.08mm). PCB layout compatibility depends on available board space for the larger body size.

Q: What compliance certifications apply to the substitute part?

A: The C330C561JAG5TA is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement in regulated industries.

Q: Why is the original HT55CN561JC classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The C330C561JAG5TA from the active GoldMax 300 series provides equivalent functionality with current manufacturing support and regulatory compliance.
