HCTC-4-14.5 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The HCTC-4-14.5 is a 4 mH common mode choke manufactured by Signal Transformer, designed for two-line power line filtering applications. This through-hole component operates at a maximum current rating of 14.5A with a DC resistance of 12 mOhm and functions across an operating temperature range of -55°C to 105°C. The component is currently in active production status and maintains ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The 8119-RC manufactured by Bourns Inc. qualifies as a direct substitute for the HCTC-4-14.5 based on the following critical parameters:

• Inductance value: 4 mH @ 1 kHz (identical)
• Current rating: 14.5A maximum (identical)
• DC resistance: 12 mOhm maximum (identical)
• Number of lines: 2 (identical)
• Mounting type: Through Hole (identical)
• Operating temperature range: -55°C ~ 105°C (identical)
• Package configuration: Vertical, 4 PC Pin (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Physical dimensions vary slightly between the main part and substitute, with the 8119-RC measuring 1.700" L x 0.900" W compared to the HCTC-4-14.5 at 1.700" L x 0.700" W. Both components maintain identical height specifications of 1.650" maximum.

Parameter Comparison

Engineering Selection Recommendations

Both the HCTC-4-14.5 and 8119-RC are active production components with identical electrical specifications and regulatory compliance status. Selection between these parts should be based on availability, packaging format (Tray versus Bulk), and physical space constraints within the application. The 8119-RC presents a slightly wider footprint (0.900" versus 0.700"), which must be evaluated against available PCB layout space. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the 8119-RC replace the HCTC-4-14.5 in existing designs?

A: Yes. The 8119-RC provides identical electrical performance with matching inductance (4 mH @ 1 kHz), current rating (14.5A), and DC resistance (12 mOhm). The primary consideration is the increased width dimension (0.900" versus 0.700"), which must be accommodated within the PCB layout.

Q: What are the key electrical parameters that define substitution eligibility?

A: Inductance value, current rating, DC resistance, number of lines, operating temperature range, and mounting type are the critical parameters. The 8119-RC matches all of these specifications with the HCTC-4-14.5.

Q: Are there packaging differences between these parts?

A: Yes. The HCTC-4-14.5 is supplied in Tray packaging, while the 8119-RC is supplied in Bulk packaging. This affects handling and storage but does not impact electrical performance.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the impact of the dimensional difference?

A: The 8119-RC is 0.200" wider than the HCTC-4-14.5. PCB layout must accommodate this increased width. All other dimensions, including length and height, are identical.
