HT11BN100KN Equivalent & Substitute Parts

Part Overview

The HT11BN100KN is a 10 pF ceramic capacitor manufactured by KEMET, rated for 50V operation with C0G/NP0 temperature coefficient characteristics. This 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 equivalent substitute components that maintain functional compatibility while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT11BN100KN is determined by the following critical parameters that must remain constant or be exceeded:

Mandatory Matching Parameters:

• Capacitance value: 10 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Axial (exact match required)
• Lead Style: Straight (exact match required)

Allowable Parameter Variations:

• Voltage Rating: Substitute parts may have equal or higher voltage ratings. The HT11BN100KN operates at 50V; substitutes rated at 100V or higher are electrically compatible.
• Operating Temperature Range: Substitute parts may have equal or narrower temperature ranges, provided the minimum operating temperature does not exceed -55°C and the maximum does not fall below the application requirement.
• Physical Dimensions: Minor variations in diameter and length are acceptable provided the component fits within the designated board space and lead spacing remains compatible.

The C410C100K1G5TA7200 qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The C410C100K1G5TA7200 is a qualified substitute for the HT11BN100KN based on the following engineering criteria:

Electrical Compatibility: The substitute maintains identical capacitance (10 pF), tolerance (±10%), and temperature coefficient (C0G/NP0) specifications. The increased voltage rating (100V versus 50V) provides additional design margin and does not compromise circuit performance in applications rated for 50V operation.

Mechanical Compatibility: Both components utilize identical axial through-hole mounting with straight leads. The substitute exhibits a marginally reduced body diameter (0.095" versus 0.100"), which presents no installation or spacing conflicts in standard PCB layouts designed for the original component.

Product Status and Compliance: The substitute is classified as active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment. The original HT11BN100KN, classified as obsolete, presents supply chain risk and potential future unavailability.

Temperature Range Consideration: The substitute operates across -55°C to 125°C, which is narrower than the original specification of -55°C to 200°C. Component selection should confirm that the application does not require sustained operation above 125°C.

Frequently Asked Questions (FAQ)

Q: Can the C410C100K1G5TA7200 be used as a direct replacement for the HT11BN100KN?

A: Yes, the C410C100K1G5TA7200 is electrically and mechanically compatible for applications operating within -55°C to 125°C. The substitute maintains identical capacitance, tolerance, and temperature coefficient specifications while providing higher voltage rating and active product status.

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

A: The C410C100K1G5TA7200 is rated for 100V operation compared to the original 50V rating. In circuit applications, a higher voltage rating provides additional safety margin and does not negatively impact performance. The component will function correctly in circuits designed for 50V operation.

Q: Are there physical dimension differences between these parts?

A: The substitute exhibits a slightly reduced body diameter (0.095" versus 0.100"), while maintaining identical length (0.170"). This minor variation is compatible with standard PCB layouts and does not affect lead spacing or mounting compatibility.

Q: What is the impact of the narrower operating temperature range on the substitute?

A: The C410C100K1G5TA7200 operates from -55°C to 125°C, compared to the original -55°C to 200°C range. Applications requiring sustained operation above 125°C must evaluate alternative solutions. For standard industrial and commercial applications operating within -55°C to 125°C, this specification is sufficient.

Q: Why is product status relevant to component selection?

A: The original HT11BN100KN is classified as obsolete, indicating discontinued production and potential supply constraints. The substitute C410C100K1G5TA7200 maintains active product status, ensuring reliable long-term availability and continued manufacturing support.

Q: Are there packaging differences between the main part and substitute?

A: The main part is supplied in standard packaging, while the substitute is available in Cut Tape (CT) format. Both utilize identical axial through-hole package types. Packaging format does not affect component electrical or mechanical performance.
