HT06AN751JC Equivalent & Substitute Parts Reference

Part Overview

The HT06AN751JC is a 750 pF ceramic capacitor manufactured by KEMET, rated for 25V operation with C0G/NP0 temperature coefficient and radial through-hole mounting. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part operates across an extended temperature range of -55°C to 200°C, making it suitable for high-temperature applications requiring stable capacitance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06AN751JC is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Capacitance value: 750 pF (exact match required)
• Temperature coefficient: C0G/NP0 (no alternatives acceptable)
• Mounting type: Through-hole radial configuration
• Lead spacing: 0.200" (5.08mm) for PCB compatibility
• Tolerance: ±5% or tighter

Acceptable Variation Criteria:

• Voltage rating: Equal to or greater than 25V
• Operating temperature range: Must accommodate the application's thermal requirements
• Physical dimensions: Minor variations acceptable if lead spacing and mounting type remain constant
• Product status: Active or obsolete status does not disqualify a substitute if electrical and mechanical parameters align

The substitute part C330C751JAG5TA meets all mandatory criteria while providing enhanced voltage rating (250V) and active product status, making it a direct functional equivalent.

Engineering Selection Recommendations

Primary Substitute: C330C751JAG5TA

The C330C751JAG5TA is the qualified equivalent for HT06AN751JC applications based on the following engineering factors:

1. Electrical Equivalence: Identical capacitance (750 pF), tolerance (±5%), and temperature coefficient (C0G/NP0) ensure circuit performance parity.

2. Voltage Margin: The 250V rating provides a 10× safety margin over the 25V requirement, enhancing reliability in applications subject to transient overvoltage conditions.

3. PCB Compatibility: Matching lead spacing (0.200") and through-hole radial configuration enable direct board-level substitution without layout modification.

4. Product Status: Active manufacturing status ensures long-term availability and supply chain stability compared to the obsolete HT06AN751JC.

5. Regulatory Compliance: ROHS3 compliance and REACH unaffected status satisfy modern procurement and environmental requirements.

Temperature Range Consideration: The substitute operates to 125°C maximum, compared to the main part's 200°C upper limit. Selection of C330C751JAG5TA is appropriate for applications with operating temperatures not exceeding 125°C. Applications requiring sustained operation above 125°C require alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can C330C751JAG5TA be used as a direct replacement for HT06AN751JC on existing PCBs?

A: Yes, for applications operating at temperatures not exceeding 125°C. The matching lead spacing (0.200"), radial through-hole configuration, and identical capacitance/tolerance specifications enable direct substitution without PCB redesign. The formed leads of the substitute may require minor insertion force adjustment compared to straight leads.

Q: What is the significance of the voltage rating difference (25V vs. 250V)?

A: The substitute's higher voltage rating does not affect circuit operation at 25V or below. The 250V rating provides additional safety margin and is acceptable in all applications where the original 25V part was specified. No circuit modification is required.

Q: Are the C0G and NP0 temperature coefficients equivalent?

A: Yes. C0G and NP0 designations are equivalent specifications for ceramic capacitors, both indicating near-zero temperature coefficient performance. Both the main part and substitute meet this specification.

Q: Does the operating temperature range difference affect substitution suitability?

A: The substitute's maximum operating temperature of 125°C is lower than the main part's 200°C. Substitution is appropriate only for applications where the capacitor operates within the -55°C to 125°C range. Applications requiring sustained operation above 125°C cannot use this substitute.

Q: What is the difference between straight leads and formed leads?

A: Straight leads (main part) are pre-cut to standard length. Formed leads (substitute) are pre-bent for insertion into standard 0.200" spaced holes. Both configurations are compatible with standard through-hole PCB mounting. Formed leads may require slightly different insertion technique but provide equivalent electrical and mechanical performance.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and procurement requirement, not a functional electrical specification. The substitute's ROHS3 compliance satisfies modern environmental and supply chain requirements. The main part's compliance status is not specified in available documentation.

Q: Can multiple substitutes be used interchangeably in the same design?

A: Only C330C751JAG5TA is identified as a qualified substitute based on the provided parameter specifications. No other alternatives meet the mandatory matching criteria for capacitance, tolerance, temperature coefficient, and lead spacing.
