Key Parameters

Substitute Part Grouping Explanation

Substitution of the HT16CW105KN is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 1 µF
• Tolerance: ±10%
• Voltage rating: 100V
• Temperature coefficient: X7R
• Operating temperature range: -55°C ~ 200°C

Mechanical Equivalence Criteria:

• Mounting type: Through Hole
• Package configuration: Axial
• Lead style: Straight

The substitute part ARA50D105KWS meets all electrical equivalence requirements and maintains through-hole axial mounting with straight leads. The primary distinction is physical size and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The ARA50D105KWS serves as the direct electrical equivalent to the obsolete HT16CW105KN. Both components share identical electrical specifications: 1 µF capacitance, ±10% tolerance, 100V rating, X7R temperature coefficient, and -55°C to 200°C operating range. Both maintain through-hole axial mounting configuration with straight leads suitable for general-purpose applications.

The transition from HT16CW105KN to ARA50D105KWS reflects a product line evolution within KEMET's industrial ceramic capacitor portfolio. The ARA50D series represents the active product line, ensuring ongoing availability and manufacturing support. Both components carry identical ECCN classification (EAR99), confirming equivalent export compliance status.

Physical dimensions differ between the two parts. The HT16CW105KN measures 0.375" diameter by 0.750" length, while the ARA50D105KWS measures 0.265" width by 0.160" thickness by 0.520" length. PCB layout and mechanical clearance requirements must be evaluated during component substitution to ensure physical fit within existing designs.

Frequently Asked Questions (FAQ)

Q: Can ARA50D105KWS directly replace HT16CW105KN in existing designs?

A: Electrical substitution is valid. Both components meet identical electrical specifications for capacitance, voltage rating, temperature coefficient, and operating temperature range. Physical dimensions differ; PCB layout compatibility must be confirmed before implementation.

Q: What is the primary reason for substituting HT16CW105KN?

A: The HT16CW105KN is classified as obsolete. The ARA50D105KWS is the active equivalent from KEMET's current product portfolio, ensuring continued availability and manufacturing support.

Q: Are there any compliance or certification differences?

A: Both components carry identical ECCN classification (EAR99). No compliance or certification differences exist between the two parts.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (1 µF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), and operating temperature range (-55°C to 200°C) must remain identical for valid substitution.

Q: How do the physical dimensions affect substitution?

A: The HT16CW105KN is larger (0.375" Dia x 0.750" L) compared to the ARA50D105KWS (0.265" W x 0.160" T x 0.520" L). Designs with space constraints may benefit from the smaller ARA50D105KWS footprint. Existing PCB layouts designed for the larger HT16CW105KN may require modification to accommodate the ARA50D105KWS.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components feature X7R temperature coefficient and operate across -55°C to 200°C, qualifying them for high-temperature industrial applications.
