HT06CN333FN Equivalent & Substitute Parts Reference

Part Overview

The HT06CN333FN is a 0.033 µF ceramic capacitor rated at 100V with C0G/NP0 temperature coefficient, manufactured by KEMET. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 200°C). The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT06CN333FN is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-negotiable):

• Capacitance value: 0.033 µF
• Voltage rating: 100V minimum
• Tolerance: ±1% or tighter
• Temperature coefficient: C0G/NP0 only

Mechanical Parameters (Non-negotiable):

• Mounting type: Through-hole radial configuration
• Lead spacing: 0.200" (5.08mm) pitch for PCB hole alignment
• Lead style: Straight or formed leads acceptable if spacing maintained

Environmental Parameters:

• Operating temperature range: -55°C to 200°C minimum
• Moisture sensitivity: Not applicable for both parts

The substitute part C052H333F1G5GA meets all mandatory electrical and mechanical criteria while offering improved product status (active vs. obsolete) and additional performance features (low ESL).

Engineering Selection Recommendations

Primary Recommendation: C052H333F1G5GA

The C052H333F1G5GA is the direct functional equivalent for HT06CN333FN replacement. Selection rationale:

1. Electrical Equivalence: Identical capacitance (0.033 µF), voltage rating (100V), tolerance (±1%), and temperature coefficient (C0G/NP0) ensure drop-in electrical compatibility.

2. Mechanical Compatibility: Matching lead spacing (0.200" / 5.08mm) and through-hole radial configuration permit direct PCB footprint substitution without layout modification.

3. Product Status: Active manufacturing status ensures long-term availability and supply chain continuity, addressing the obsolescence of the original part.

4. Compliance: ROHS3 compliance and REACH unaffected status satisfy current regulatory requirements for new production and repair applications.

5. Physical Characteristics: The substitute features a smaller footprint (0.190" x 0.090" vs. 0.300" x 0.150") and lower seated height (0.245" vs. 0.300"), providing design flexibility for space-constrained applications while maintaining all electrical specifications.

6. Additional Features: Low ESL characteristic of the C052H333F1G5GA provides performance enhancement without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can C052H333F1G5GA be used as a direct replacement for HT06CN333FN on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.200" / 5.08mm), capacitance (0.033 µF), voltage rating (100V), and temperature coefficient (C0G/NP0). The substitute will function identically in the circuit. The smaller physical dimensions of the substitute may require verification of clearance in confined board areas, but electrical performance is equivalent.

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

A: Straight leads on the HT06CN333FN require manual bending before insertion into PCB holes. Formed leads on the C052H333F1G5GA are pre-shaped for standard 0.200" spacing, reducing assembly labor. Both configurations achieve the same 0.200" pitch and are mechanically compatible with standard PCB hole patterns.

Q: Why is the substitute part physically smaller?

A: The C052H333F1G5GA uses optimized dielectric and construction techniques while maintaining identical electrical specifications. Smaller size does not affect electrical performance; it reflects manufacturing advances in ceramic capacitor design.

Q: Are there any temperature or voltage derating considerations?

A: No. Both parts operate identically across the -55°C to 200°C range at 100V rating. No derating adjustments are required when substituting.

Q: What does ROHS3 compliance mean for this part?

A: ROHS3 compliance indicates the C052H333F1G5GA meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This is a regulatory requirement for products sold in the European Union and many other markets.

Q: Is the substitute part available in the same quantities as the original?

A: Availability varies by distributor and time. The C052H333F1G5GA is an active product with ongoing production, providing better long-term availability than the obsolete HT06CN333FN. Current inventory should be verified with authorized distributors.
