HT08BW103KN Equivalent & Substitute Parts

Part Overview

The HT08BW103KN is a 10000 pF ceramic capacitor manufactured by KEMET, rated for 50V operation with X7R temperature coefficient characteristics. This component is designed for general-purpose applications requiring high-temperature stability across the -55°C to 200°C operating range. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the HT08BW103KN is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 10000 pF (exact match)
• Tolerance: ±10% (exact match)
• Voltage rating: 50V (exact match or higher)
• Temperature coefficient: X7R (exact match)
• Operating temperature range: -55°C to 200°C (exact match or wider)

Mechanical Equivalence Requirements:

• Mounting type: Through Hole (exact match)
• Package configuration: Radial (exact match)
• Lead style: Straight (exact match)

The ARR05B103KGS meets all electrical equivalence criteria and maintains mechanical compatibility as a radial through-hole component with straight leads. The primary distinction between the main part and its substitute is physical size and product status transition from obsolete to active manufacturing.

Parameter Comparison

Engineering Selection Recommendations

The ARR05B103KGS is the direct electrical equivalent for the obsolete HT08BW103KN, providing identical capacitance, voltage rating, tolerance, and temperature coefficient specifications. Both components are manufactured by KEMET and classified under the same HTSUS code (8532.24.0060) with matching ECCN designation (EAR99).

The transition from HT08BW103KN to ARR05B103KGS represents a product line consolidation within KEMET's industrial X7R ceramic capacitor portfolio. The ARR05B103KGS maintains active production status with confirmed inventory availability (960 pcs), ensuring supply chain continuity for new designs and replacement applications.

Physical dimensions differ between the two parts, with ARR05B103KGS providing a more compact footprint (5.08mm x 2.54mm versus 12.70mm x 6.85mm). Lead spacing is reduced from 0.400" to 0.200", requiring PCB layout modification for direct substitution. Electrical performance and thermal characteristics remain functionally equivalent across all specified operating conditions.

RoHS compliance status differs: HT08BW103KN compliance is not specified in available documentation, while ARR05B103KGS is explicitly RoHS non-compliant. REACH status applies to ARR05B103KGS. These regulatory considerations must be evaluated against specific application requirements and regional compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can ARR05B103KGS be used as a direct replacement for HT08BW103KN without circuit modification?

A: Electrical substitution is valid. The components share identical capacitance (10000 pF), voltage rating (50V), tolerance (±10%), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C). However, physical dimensions and lead spacing differ significantly, requiring PCB layout redesign for mechanical compatibility.

Q: What are the key differences between HT08BW103KN and ARR05B103KGS?

A: Electrical specifications are equivalent. Physical differences include: HT08BW103KN measures 12.70mm x 6.85mm with 0.400" lead spacing; ARR05B103KGS measures 5.08mm x 2.54mm with 0.200" lead spacing. Product status transitions from obsolete to active manufacturing. RoHS and REACH compliance status differs between the two parts.

Q: Is the smaller size of ARR05B103KGS suitable for high-temperature applications?

A: Yes. Both components operate across the identical temperature range (-55°C to 200°C) with X7R temperature coefficient characteristics. Physical size reduction does not affect thermal performance or electrical stability within specified operating conditions.

Q: What is the lead spacing difference and why does it matter?

A: HT08BW103KN has 0.400" (10.16mm) lead spacing; ARR05B103KGS has 0.200" (5.08mm) lead spacing. This difference requires modification of PCB hole patterns and trace routing. Existing PCB designs cannot accommodate ARR05B103KGS without layout revision.

Q: Are there compliance considerations for substitution?

A: Both parts share EAR99 ECCN classification and 8532.24.0060 HTSUS code. ARR05B103KGS is RoHS non-compliant and REACH-affected. Verify compliance requirements against your specific application and regional regulations before implementation.

Q: What inventory status should influence substitution decisions?

A: HT08BW103KN is obsolete with 845 pcs available. ARR05B103KGS is active production with 960 pcs in stock. For new designs, ARR05B103KGS ensures long-term supply availability. For legacy system maintenance, existing HT08BW103KN stock may be preferred if PCB compatibility is maintained.
