HCTC-5-8.9 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The HCTC-5-8.9 is a 5 mH common mode choke manufactured by Signal Transformer, designed for two-line power line filtering applications. This through-hole component operates at currents up to 8.9A with a maximum DC resistance of 22 mOhm and functions across the temperature range of -55°C to 105°C. The part is currently in active production status. Equivalent parts may be required due to supply chain considerations, inventory availability, or specific packaging requirements for manufacturing operations.

Key Parameters

Substitute Part Grouping Explanation

The HCTC-5-8.9 has one identified equivalent part: the Bourns 8113-RC. Substitution eligibility is determined by the following critical parameters:

• Inductance value: 5 mH @ 1 kHz (exact match required)
• Current rating: 8.9A maximum (exact match required)
• DC resistance: 22 mOhm maximum (exact match required)
• Number of lines: 2 (exact match required)
• Mounting type: Through Hole (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Package configuration: Vertical, 4 PC Pin (exact match required)

The Bourns 8113-RC meets all electrical and mechanical substitution criteria. Physical dimensions differ slightly in width (0.800" vs 0.600"), but both components maintain identical height and pin configuration, allowing functional interchangeability in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the HCTC-5-8.9 and 8113-RC are active production components with identical electrical specifications and regulatory compliance. Selection between these parts should be based on:

• Packaging format availability (Signal Transformer supplies in Tray; Bourns supplies in Bulk)
• Current inventory levels and lead times
• PCB layout constraints related to component width (0.600" vs 0.800")
• Supplier qualification requirements for your manufacturing process

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental regulations. The identical operating temperature range, current rating, and inductance characteristics ensure functional equivalence in power line filtering applications.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 8113-RC be used as a direct replacement for the HCTC-5-8.9?

A: Yes. Both components share identical electrical specifications (5 mH inductance, 8.9A current rating, 22 mOhm DCR) and mechanical mounting configuration (through-hole, vertical, 4-pin). The width difference (0.800" vs 0.600") does not affect electrical performance or pin compatibility.

Q: What is the primary difference between these two parts?

A: The main differences are manufacturer (Signal Transformer vs Bourns), packaging format (Tray vs Bulk), and physical width. Electrical performance and temperature operating range are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN and HTSUS codes.

Q: Does the width difference affect PCB layout?

A: The Bourns 8113-RC is 0.200" wider (0.800" vs 0.600"). PCB footprint spacing must accommodate this dimension. Both components maintain the same length (1.450") and height (1.500").

Q: Which part should I select for new designs?

A: Selection depends on supply chain factors, packaging preferences, and PCB layout constraints. Both parts are active production components with equivalent electrical performance for power line common mode filtering applications.
