HT08BN104JN Equivalent & Substitute Parts

Part Overview

The HT08BN104JN is a 0.1 µF ±5% 50V ceramic capacitor manufactured by KEMET, featuring C0G/NP0 temperature coefficient and radial through-hole mounting. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing production and maintenance applications. The part operates across an extended temperature range of -55°C to 200°C, making it suitable for high-temperature industrial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT08BN104JN is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance: 0.1 µF (exact match)
• Tolerance: ±5% (exact match)
• Voltage Rating: 50V (exact match or higher)
• Temperature Coefficient: C0G/NP0 (exact match)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole Radial (exact match)
• Lead Style: Radial configuration (straight or formed leads acceptable)
• Package Classification: Radial ceramic capacitor

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected status

Two substitute parts meet these criteria: C052H104J5G5GA (KEMET, active status) and FK20C0G1H104JN000 (TDK Corporation, not for new designs status).

Parameter Comparison

Engineering Selection Recommendations

C052H104J5G5GA (KEMET) - Primary Substitute:

This part is the preferred substitute for new designs and ongoing production. It maintains identical electrical specifications (0.1 µF, ±5%, 50V, C0G/NP0) and operating temperature range (-55°C to 200°C). The part carries active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance and REACH unaffected status align with the original part's regulatory requirements. Physical dimensions are smaller (4.83mm x 2.29mm versus 12.70mm x 6.35mm), which may require PCB layout verification for through-hole spacing compatibility.

FK20C0G1H104JN000 (TDK Corporation) - Secondary Substitute:

This part provides electrical equivalence across all critical parameters but operates within a reduced temperature range (-55°C to 125°C). Selection of this substitute is appropriate only for applications where the maximum operating temperature does not exceed 125°C. The part is designated "Not For New Designs," limiting its suitability for new product development. However, it remains available in high inventory quantities (7602 units) for legacy system maintenance and repair applications. ROHS3 compliance and REACH unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can C052H104J5G5GA be used as a direct replacement for HT08BN104JN in all applications?

A: C052H104J5G5GA meets all electrical specifications and maintains the full operating temperature range. However, physical dimensions differ significantly. The substitute measures 4.83mm x 2.29mm with 5.08mm lead spacing, compared to the original 12.70mm x 6.35mm with 10.16mm lead spacing. PCB through-hole positioning and lead spacing must be verified before installation.

Q: What is the temperature limitation of the TDK FK20C0G1H104JN000 substitute?

A: The FK20C0G1H104JN000 operates from -55°C to 125°C, compared to the original part's -55°C to 200°C range. This 75°C reduction in maximum operating temperature restricts its use to applications where ambient or component temperatures remain below 125°C.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both C052H104J5G5GA and FK20C0G1H104JN000 carry ROHS3 compliance certification and REACH unaffected status, matching the original HT08BN104JN specifications.

Q: Why is the KEMET C052H104J5G5GA recommended over the TDK part?

A: The KEMET substitute maintains the full -55°C to 200°C operating temperature range and carries active product status, ensuring continued availability. The TDK part is designated "Not For New Designs" and operates only to 125°C, limiting its application scope.

Q: Can lead spacing differences affect circuit performance?

A: Lead spacing differences affect PCB layout compatibility only. Electrically, both substitutes are equivalent. However, physical board modifications may be required to accommodate the smaller lead spacing of the KEMET C052H104J5G5GA (5.08mm versus 10.16mm).
