Bourns 7114-RC Common Mode Choke Equivalent & Substitute Parts

Part Overview

The Bourns 7114-RC is a 2.55 mH common mode choke designed for two-line filtering applications in through-hole configurations. This component is rated for 2A maximum current with 85 mOhm DC resistance and operates across the temperature range of -55°C to 105°C. The part maintains Active product status and is ROHS3 compliant, making it suitable for modern electronic applications requiring electromagnetic interference suppression.

Substitute parts are identified when they maintain identical electrical performance specifications while potentially offering alternative physical dimensions or improved component characteristics within the same product series.

Key Parameters

Substitute Part Grouping Explanation

The Bourns 7109-RC qualifies as a parametric equivalent to the 7114-RC based on the following critical electrical specifications:

• Inductance value: 2.55 mH @ 1 kHz (identical)
• Number of lines: 2 (identical)
• Current rating: 2A (identical)
• Operating temperature range: -55°C ~ 105°C (identical)
• Mounting type: Through Hole (identical)
• Package configuration: Vertical, No Base, 4 PC Pin (identical)
• Compliance certifications: ROHS3 Compliant, REACH Unaffected (identical)

The primary distinction between these parts is the DC resistance specification and physical dimensions. The 7109-RC features a lower maximum DC resistance of 75 mOhm compared to the 7114-RC at 85 mOhm, with correspondingly reduced physical dimensions (0.700" diameter vs. 0.900" diameter).

Parameter Comparison

Engineering Selection Recommendations

Both the 7114-RC and 7109-RC maintain Active product status within the Bourns 7100 series, ensuring continued availability and support. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for modern electronics manufacturing.

The 7109-RC presents improved electrical performance through lower DC resistance (75 mOhm vs. 85 mOhm) while maintaining identical inductance and current rating specifications. The reduced physical footprint of the 7109-RC (0.700" diameter vs. 0.900" diameter) may provide advantages in space-constrained applications, provided PCB layout accommodates the alternative dimensions.

Selection between these parts should be based on available PCB space and DC resistance requirements specific to the application circuit. Both parts are electrically interchangeable for two-line common mode filtering at 2A current levels.

Frequently Asked Questions (FAQ)

Q: Can the 7109-RC directly replace the 7114-RC in existing designs?

A: Electrical substitution is valid based on identical inductance (2.55 mH @ 1 kHz), current rating (2A), and operating temperature range. Physical dimensions differ; verify PCB layout accommodates the 7109-RC's smaller footprint (0.700" diameter vs. 0.900" diameter) before implementation.

Q: What is the significance of the DC resistance difference between these parts?

A: The 7109-RC features 75 mOhm maximum DC resistance compared to the 7114-RC at 85 mOhm. Lower DC resistance reduces power dissipation in the component. Applications sensitive to heat generation may benefit from the 7109-RC specification.

Q: Are both parts suitable for the same current and temperature operating conditions?

A: Yes. Both parts are rated for 2A maximum current and operate across -55°C to 105°C. Electrical performance remains equivalent across this temperature range.

Q: Do compliance certifications differ between these parts?

A: No. Both the 7114-RC and 7109-RC maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What packaging considerations apply to these through-hole components?

A: Both parts use identical package configuration: Vertical, No Base, 4 PC Pin. Pin spacing and lead configuration are compatible with standard through-hole PCB designs. Physical diameter and height differences require layout verification.
