Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HT14BN103KN is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 10000 pF
• Tolerance: ±10%
• Voltage rating: 50V (minimum)
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C ~ 200°C (minimum)
• Mounting type: Through Hole
• Package type: Axial
• Lead style: Straight

The ACA39B103KWS meets all mandatory substitution criteria. Both components are manufactured by KEMET and share identical electrical specifications. The primary difference is physical dimension: the HT14BN103KN features a 0.155" diameter cylindrical body, while the ACA39B103KWS uses a 0.150" square cross-section. Both maintain the same 0.400" axial length. This dimensional variation is within acceptable tolerance for through-hole axial component substitution in standard PCB layouts.

Engineering Selection Recommendations

The ACA39B103KWS is the direct functional equivalent for the obsolete HT14BN103KN. Selection of the ACA39B103KWS is supported by the following engineering factors:

Product Status: The ACA39B103KWS is classified as Active production status, ensuring long-term availability and supply chain continuity. The HT14BN103KN obsolete status necessitates transition to an alternative.

Electrical Equivalence: Both components share identical electrical specifications across all critical parameters: 10000 pF capacitance, ±10% tolerance, 50V rating, C0G/NP0 temperature coefficient, and -55°C to 200°C operating range.

Compliance: Both parts carry identical ECCN classification (EAR99) and are manufactured by the same supplier, ensuring regulatory consistency.

Physical Compatibility: The dimensional difference (cylindrical 0.155" diameter versus square 0.150" cross-section) does not affect electrical performance or standard through-hole PCB mounting. Both components maintain 0.400" axial length and straight lead configuration.

Frequently Asked Questions (FAQ)

Q: Can the ACA39B103KWS directly replace the HT14BN103KN in existing designs?

A: Yes. The ACA39B103KWS is electrically and functionally equivalent. Both components have identical capacitance, voltage rating, temperature coefficient, and operating temperature range. The physical dimension difference (body shape) does not affect electrical performance or standard through-hole mounting compatibility.

Q: What is the primary reason for substitution?

A: The HT14BN103KN is classified as obsolete. The ACA39B103KWS is the active production equivalent from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there any compliance or certification differences?

A: No. Both components carry identical ECCN classification (EAR99) and are manufactured by KEMET under equivalent quality standards.

Q: Does the body dimension difference affect PCB layout?

A: The ACA39B103KWS uses a 0.150" square cross-section compared to the HT14BN103KN's 0.155" circular cross-section. Both fit standard through-hole axial component footprints. Verify PCB hole spacing accommodates the square geometry if tight layout constraints exist.

Q: What is the inventory status of the substitute part?

A: The ACA39B103KWS has 1116 pieces in stock as new original inventory, providing immediate availability for production requirements.
