Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT55CN272JC is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 2700 pF (exact match required)
• Temperature coefficient: C0G/NP0 (exact match required for circuit stability)
• Mounting type: Through-hole radial (exact match required for PCB compatibility)
• Lead spacing: 0.200" (5.08mm) (exact match required for footprint compatibility)
• Tolerance: ±5% or tighter (substitute tolerance must not exceed ±5%)

Allowable Variation Parameters:

• Voltage rating: Substitute must equal or exceed 100V
• Operating temperature range: Substitute must support the application's required temperature range; extended range capability is acceptable
• Physical dimensions: Larger package sizes are acceptable if lead spacing remains constant
• Product status: Active status is preferred for long-term availability

The identified substitute C330C272JAG5TA meets all mandatory matching criteria while offering enhanced voltage rating (250V) and active product status.

Engineering Selection Recommendations

Primary Substitute: C330C272JAG5TA

The C330C272JAG5TA is the direct electrical and mechanical equivalent of the HT55CN272JC for applications operating within -55°C to 125°C. This substitute provides:

• Identical capacitance (2700 pF) and tolerance (±5%)
• Identical temperature coefficient (C0G/NP0) ensuring equivalent circuit performance
• Identical lead spacing (0.200") and through-hole radial mounting for direct PCB footprint compatibility
• Enhanced voltage rating (250V vs. 100V), providing additional design margin
• Active product status ensuring long-term procurement availability
• ROHS3 compliance and REACH unaffected status for regulatory requirements

Application Constraint: The C330C272JAG5TA operating temperature range (-55°C to 125°C) is narrower than the original part (-55°C to 200°C). This substitute is suitable only for applications where the maximum operating temperature does not exceed 125°C. For applications requiring operation above 125°C, alternative sources must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can C330C272JAG5TA be used as a direct replacement for HT55CN272JC in all applications?

A: The C330C272JAG5TA is a direct replacement for applications operating at or below 125°C. If your application requires operation above 125°C, this substitute is not suitable. Verify your circuit's maximum operating temperature before selection.

Q: Why does the substitute have a higher voltage rating (250V vs. 100V)?

A: Higher voltage ratings do not negatively affect circuit performance. A 250V-rated capacitor functions identically to a 100V-rated capacitor in a 100V circuit, with the benefit of additional safety margin and reduced stress on the component.

Q: Are the physical dimensions compatible with the original PCB layout?

A: Yes. Both parts have identical lead spacing (0.200" / 5.08mm) and radial through-hole mounting. The substitute has a slightly larger body (0.280" L x 0.160" W vs. 0.200" L x 0.100" W), but this does not affect PCB footprint compatibility. Verify available board space for the larger package height (0.360" vs. 0.200").

Q: What does C0G/NP0 temperature coefficient mean for substitution?

A: C0G and NP0 are equivalent designations for the same temperature coefficient specification, indicating minimal capacitance change across the operating temperature range. Both the main part and substitute use this specification, ensuring identical frequency and temperature stability characteristics.

Q: Is the substitute RoHS compliant?

A: Yes. The C330C272JAG5TA is ROHS3 compliant and REACH unaffected. If regulatory compliance is required for your application, this substitute meets current environmental standards.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The identified substitute from the same manufacturer provides equivalent functionality with active product status, ensuring continued availability.

Q: Can I use the substitute in high-temperature applications above 125°C?

A: No. The substitute's maximum operating temperature is 125°C. For applications requiring 200°C operation, you must source alternative components rated for extended temperature ranges.
