HT13CW104KN Equivalent & Substitute Parts

Part Overview

The HT13CW104KN is a 0.1 µF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KEMET. This axial through-hole component is designed for high-temperature applications with an operating range of -55°C to 200°C. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and procurement planning. Equivalent parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT13CW104KN is based on strict electrical and mechanical parameter matching. The following criteria determine valid equivalents:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 0.1 µF
• Tolerance: ±10%
• Voltage rating: 100V minimum
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 200°C minimum

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through hole
• Package case: Axial configuration
• Lead style: Straight leads

The substitute part ARA39D104KGS meets all electrical requirements and maintains the same axial through-hole mounting configuration. Both parts are manufactured by KEMET and share identical electrical specifications. The primary difference is physical dimension and product status, with ARA39D104KGS being an active product line offering improved availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ARA39D104KGS

The ARA39D104KGS is the direct electrical equivalent for the obsolete HT13CW104KN. Both components share identical capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature specifications. The substitute part is manufactured by the same supplier (KEMET) and maintains full compatibility with the original circuit design from an electrical standpoint.

Product Status Consideration: The HT13CW104KN is classified as obsolete, while ARA39D104KGS is an active product. This status difference makes ARA39D104KGS the preferred choice for new procurement and long-term supply chain continuity.

Compliance Advantage: ARA39D104KGS carries ROHS3 compliance certification and REACH affected status documentation, providing enhanced regulatory compliance for applications subject to environmental standards.

Physical Dimension Consideration: The substitute part features a larger physical envelope (0.150" Square x 0.400" L versus 0.135" Dia x 0.260" L). PCB layout verification is required to confirm adequate board space for the larger axial package. The increased size does not affect electrical performance but requires mechanical fit validation during integration.

Frequently Asked Questions (FAQ)

Q: Can ARA39D104KGS be used as a direct replacement for HT13CW104KN in existing circuits?

A: Yes, from an electrical standpoint. Both parts have identical capacitance (0.1 µF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C). Physical board space must be verified due to the larger package dimensions of the substitute.

Q: What is the primary reason for substitution?

A: The HT13CW104KN is obsolete. ARA39D104KGS is an active product from the same manufacturer, ensuring reliable long-term availability and supply chain stability.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are 0.1 µF ±10% 100V X7R ceramic capacitors with identical electrical specifications and operating characteristics.

Q: How do the physical dimensions differ?

A: HT13CW104KN measures 0.135" diameter by 0.260" length (3.43mm x 6.60mm). ARA39D104KGS measures 0.150" square by 0.400" length (3.81mm x 10.16mm). The substitute is larger in both diameter and length. PCB layout must accommodate this size increase.

Q: Will the larger package affect circuit performance?

A: No. The larger physical size does not impact electrical performance, capacitance value, or circuit behavior. Only mechanical fit on the PCB requires verification.

Q: What compliance certifications does the substitute offer?

A: ARA39D104KGS is ROHS3 compliant and REACH affected. The original part's compliance status is not specified in available documentation.

Q: Can both parts be used interchangeably in the same design?

A: Electrically yes, mechanically no. The different package sizes mean both parts cannot occupy the same PCB footprint. Design must be adapted to accommodate the substitute's larger dimensions, or inventory of the original part must be secured before obsolescence.

Q: What is the lead spacing for these axial components?

A: Lead spacing information is not provided in the available technical documentation for either part.
