HT14BN392JN Equivalent & Substitute Parts Reference

Part Overview

The HT14BN392JN is a 3900 pF ceramic capacitor manufactured by KEMET, rated for 50V with C0G/NP0 temperature coefficient and axial through-hole mounting. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives from current production lines. The part operates across an extended temperature range of -55°C to 200°C, making it suitable for high-temperature industrial applications. Locating substitute components with identical electrical specifications and compatible physical dimensions is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HT14BN392JN are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Non-negotiable):

• Capacitance value: 3900 pF
• Voltage rating: 50V minimum
• Tolerance: ±5% or tighter
• Temperature coefficient: C0G/NP0 only
• Operating temperature range: -55°C to 200°C minimum

Mechanical Parameters (Required for PCB Integration):

• Mounting type: Through-hole axial configuration
• Lead style: Straight leads
• Package case: Axial ceramic capacitor

Compliance Considerations:

• RoHS and REACH status alignment
• ECCN and HTSUS classifications

The ACA25B392JWS qualifies as a direct substitute because it maintains all critical electrical specifications while offering active product status and improved physical dimensions for space-constrained applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: ACA25B392JWS

The ACA25B392JWS is the direct electrical equivalent of the HT14BN392JN. Both components share identical capacitance, voltage rating, tolerance, temperature coefficient, and operating temperature specifications. The substitute part is manufactured by the same supplier (KEMET) and maintains equivalent regulatory compliance status under REACH and ECCN classifications.

The ACA25B392JWS holds active product status, ensuring continued availability and supply chain reliability compared to the obsolete HT14BN392JN. This transition eliminates long-term procurement risk associated with end-of-life components.

Physical Dimension Consideration:

The ACA25B392JWS features reduced physical dimensions (0.100" square x 0.270" length versus 0.155" diameter x 0.400" length). This dimensional difference represents a space optimization benefit. PCB layout verification is necessary to confirm that the smaller footprint accommodates existing through-hole pad spacing and lead hole positioning. If the original PCB design requires the larger form factor, dimensional compatibility must be assessed during integration.

Compliance Alignment:

Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications. The RoHS non-compliant status of the main part is preserved in the substitute, ensuring regulatory consistency within the application context.

Frequently Asked Questions (FAQ)

Q: Can the ACA25B392JWS be used as a direct replacement for the HT14BN392JN?

A: Yes, from an electrical standpoint. Both components have identical capacitance (3900 pF), voltage rating (50V), tolerance (±5%), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 200°C). Both are through-hole axial components with straight leads. Physical dimension differences require PCB layout verification to confirm lead hole spacing compatibility.

Q: What is the primary reason for substitution?

A: The HT14BN392JN is classified as obsolete. The ACA25B392JWS is an active product from the same manufacturer, providing assured long-term availability and supply chain continuity.

Q: Are there any compliance differences between the two parts?

A: No. Both components share identical REACH Unaffected status, EAR99 ECCN classification, and HTSUS code (8532.24.0040). RoHS non-compliant status is consistent across both parts.

Q: How do the physical dimensions differ?

A: The HT14BN392JN measures 0.155" diameter x 0.400" length (3.94mm x 10.16mm). The ACA25B392JWS measures 0.100" square x 0.270" length (2.52mm x 6.86mm). The substitute is significantly smaller. PCB through-hole pad spacing must be verified for compatibility.

Q: What parameters must remain identical for substitution to be valid?

A: Capacitance value, voltage rating, tolerance, temperature coefficient (C0G/NP0), operating temperature range, mounting type (through-hole axial), and lead style (straight) must all match or exceed the original specification.

Q: Is moisture sensitivity a consideration?

A: The HT14BN392JN specifies MSL 1 (Unlimited). The ACA25B392JWS lists MSL as Not Applicable. Both designations indicate minimal moisture sensitivity for standard handling and storage conditions.
