Substitute Part Grouping Explanation

Substitution of the HT14BN103JC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 10000 pF (exact match)
• Tolerance: ±5% (exact match)
• Voltage rating: 50V (exact match or higher)
• Temperature coefficient: C0G/NP0 (exact match for stability requirements)
• Operating temperature range: -55°C ~ 200°C (exact match)

Mechanical Equivalence Requirements:

• Mounting type: Through Hole (exact match)
• Package case: Axial (exact match)
• Lead style: Straight (exact match)

The substitute part ACA39B103JWS meets all electrical and mechanical equivalence criteria. The primary distinction is product status: HT14BN103JC is obsolete, while ACA39B103JWS is active production, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The ACA39B103JWS is the direct active equivalent for the obsolete HT14BN103JC. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts are identical in capacitance (10000 pF), tolerance (±5%), voltage rating (50V), and temperature coefficient (C0G/NP0). The operating temperature range of -55°C to 200°C is maintained, ensuring performance in high-temperature applications.

Mechanical Compatibility: Both components utilize through-hole axial mounting with straight leads. Physical dimensions are functionally equivalent for PCB layout purposes, with the substitute featuring a 0.150" square profile versus the original 0.155" diameter profile, both maintaining the 0.400" length and compatible lead spacing for standard through-hole assembly.

Supply Chain Status: The transition from obsolete HT14BN103JC to active ACA39B103JWS ensures long-term component availability, production continuity, and compliance with current manufacturing standards. Both parts carry identical ECCN (EAR99) classification.

Regulatory Compliance: Both components are manufactured by KEMET under equivalent industrial-grade specifications for high-temperature ceramic capacitor applications. The substitute maintains REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can ACA39B103JWS be used as a direct replacement for HT14BN103JC in existing designs?

A: Yes. The ACA39B103JWS is electrically and mechanically equivalent. All critical parameters—capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature range—are identical. The physical dimension difference (0.150" square versus 0.155" diameter) does not affect PCB compatibility for standard through-hole layouts.

Q: What is the primary reason for substitution?

A: The HT14BN103JC is obsolete. The ACA39B103JWS is the active production equivalent from KEMET, ensuring continued availability and supply chain reliability.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ECCN classification (EAR99). The substitute maintains equivalent regulatory status for industrial applications.

Q: Does the physical dimension difference affect circuit performance?

A: No. The dimension difference (profile shape and diameter) does not affect electrical performance or circuit function. Both maintain identical lead spacing and axial configuration suitable for through-hole assembly.

Q: Is the ACA39B103JWS suitable for high-temperature applications?

A: Yes. The substitute maintains the full -55°C to 200°C operating temperature range with C0G/NP0 temperature coefficient stability, identical to the original part.

Q: Can inventory of HT14BN103JC be replaced with ACA39B103JWS?

A: Yes. For new production and inventory replenishment, ACA39B103JWS is the recommended active equivalent. Existing HT14BN103JC stock can be transitioned to ACA39B103JWS without design or assembly modifications.
