HT08BN104GN Equivalent & Substitute Parts

Part Overview

The HT08BN104GN is a 0.1 µF ceramic capacitor rated at 50V with C0G/NP0 temperature coefficient, manufactured by KEMET. 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, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT08BN104GN is determined by strict alignment with the following critical parameters:

Mandatory Match Criteria:

• Capacitance value: 0.1 µF (no tolerance variation)
• Temperature coefficient: C0G/NP0 (ensures frequency and temperature stability)
• Mounting type: Through Hole Radial (PCB assembly compatibility)
• Lead spacing: 0.400" (10.16mm) (footprint compatibility)
• Voltage rating: 50V minimum (electrical safety requirement)
• Tolerance: ±2% or tighter (circuit performance specification)

Acceptable Variation:

• Operating temperature range: Substitute may have a narrower upper temperature limit if the application does not require the full -55°C to 200°C range
• Physical dimensions: Minor variations in body length and width are acceptable provided lead spacing and mounting type remain unchanged

The SR505A104GAR from KYOCERA AVX meets all mandatory criteria and qualifies as a direct substitute, with the exception of operating temperature range (-55°C to 125°C versus -55°C to 200°C).

Engineering Selection Recommendations

SR505A104GAR Selection Criteria:

The SR505A104GAR is suitable as a substitute for the HT08BN104GN in applications where the operating temperature does not exceed 125°C. This part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete HT08BN104GN.

Temperature Range Consideration:

Applications requiring sustained operation above 125°C cannot use the SR505A104GAR as a direct substitute. The HT08BN104GN's extended temperature range to 200°C is a distinguishing feature. In such cases, alternative high-temperature ceramic capacitors with matching electrical specifications must be evaluated separately.

Compliance Status:

The SR505A104GAR carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications.

Frequently Asked Questions (FAQ)

Q: Can SR505A104GAR replace HT08BN104GN in all applications?

A: The SR505A104GAR is electrically and mechanically compatible with the HT08BN104GN for applications operating at or below 125°C. Applications requiring operation above 125°C require alternative components.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G/NP0 designates a temperature coefficient of 0 ppm/°C, meaning capacitance remains stable across temperature variations. This specification must be matched exactly; substitutes with different temperature coefficients (such as X7R or Y5V) are not acceptable.

Q: Are the physical dimensions interchangeable?

A: The HT08BN104GN measures 0.500" L x 0.270" W, while the SR505A104GAR measures 0.500" L x 0.200" W. Both share identical lead spacing (0.400") and mounting type (Through Hole Radial), ensuring PCB footprint compatibility. The width difference does not affect circuit board layout.

Q: What does "obsolete" status mean for the HT08BN104GN?

A: Obsolete status indicates the manufacturer has discontinued production. The SR505A104GAR, with active production status, provides procurement continuity and ensures availability for future orders and replacements.

Q: Are there compliance differences between these parts?

A: Both parts share identical ECCN and HTSUS classifications. The SR505A104GAR includes ROHS3 compliance and REACH Unaffected status, meeting current regulatory standards.
