Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLF14CB6830R2K1 is determined by the following critical parameters:

Core Functional Parameters:

• Inductance value: 68 mH (primary filtering characteristic)
• Number of lines: 2 (common mode choke configuration)
• Filter type: Power line (application category)
• Mounting type: Through hole (mechanical compatibility)
• Package configuration: Vertical, 4 PC pin (physical and electrical interface)

Operating Parameters:

• AC voltage rating: 250V (electrical safety requirement)
• Current rating: Must meet or exceed 200 mA application requirement
• DC resistance: Lower values indicate improved efficiency; higher values remain acceptable if current rating is sufficient
• Operating temperature range: Must encompass or exceed -25°C to 105°C

The B82731M2401A033 from EPCOS - TDK Electronics qualifies as a substitute based on matching inductance value, line configuration, filter type, mounting type, and package style. The substitute demonstrates enhanced electrical performance through higher current rating (400 mA) and lower DC resistance (3 Ohm typical), while maintaining the same AC voltage rating and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The B82731M2401A033 is a direct functional substitute for the obsolete TLF14CB6830R2K1 based on the following engineering criteria:

Functional Equivalence: Both components provide 68 mH inductance in a 2-line common mode choke configuration for power line filtering. The substitute maintains the same AC voltage rating (250V) and through-hole mounting interface with vertical, 4-pin package configuration.

Performance Enhancement: The B82731M2401A033 offers superior electrical characteristics: 400 mA current rating (double the original 200 mA specification) and 3 Ohm typical DC resistance (compared to 6.5 Ohm maximum). These improvements provide design margin and reduced power dissipation in the filtering circuit.

Compliance and Availability: The substitute carries active product status with established supply availability (12,518 pieces in stock). It holds multiple approval certifications (ENEC, UR, VDE) and complies with ROHS3 and REACH regulatory requirements, supporting modern procurement and environmental compliance standards.

Physical Compatibility: The substitute exhibits slightly reduced physical dimensions (21.00mm L x 15.00mm W x 20.50mm H versus 22.00mm L x 17.00mm W x 23.00mm H), which may require PCB layout verification but generally presents no integration obstacles for through-hole mounting applications.

Temperature Range: The substitute operates across -40°C to 125°C, exceeding the original -25°C to 105°C range and providing enhanced thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the B82731M2401A033 directly replace the TLF14CB6830R2K1 in existing designs?

A: Yes. Both components share identical inductance values (68 mH), line configuration (2-line), filter type (power line), mounting method (through hole), and package style (vertical, 4-pin). The substitute is electrically and mechanically compatible for direct substitution.

Q: What are the key differences between these two components?

A: The primary differences are product status (obsolete versus active), current rating (200 mA versus 400 mA), DC resistance (6.5 Ohm maximum versus 3 Ohm typical), operating temperature range (-25°C to 105°C versus -40°C to 125°C), physical dimensions (slightly smaller for the substitute), and regulatory certifications (ENEC, UR, VDE for the substitute).

Q: Does the lower DC resistance of the substitute affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation in the component. This represents an improvement over the original specification and does not negatively affect circuit performance. The filtering characteristics remain equivalent due to matching inductance values.

Q: Are there PCB layout considerations when switching to the B82731M2401A033?

A: The substitute has slightly reduced dimensions. Verify that the smaller footprint (21.00mm L x 15.00mm W) and height (20.50mm) accommodate existing PCB hole spacing and clearance requirements. Through-hole pin configuration remains identical, simplifying mechanical integration.

Q: What regulatory compliance does the substitute provide?

A: The B82731M2401A033 holds ENEC, UR, and VDE certifications, complies with ROHS3 requirements, and is REACH-affected. These certifications support compliance with modern electrical safety and environmental standards applicable to power line filtering components.

Q: Is the higher current rating of the substitute a concern for existing applications?

A: No. The 400 mA rating of the substitute exceeds the 200 mA requirement of the original design, providing design margin without adverse effects. Applications operating at or below 200 mA experience no negative impact from the higher-rated component.

Q: What is the inductance measurement frequency difference between these parts?

A: The original part specifies 68 mH @ 1 kHz, while the substitute specifies 68 mH @ 10 kHz. Both deliver the same inductance value at their respective measurement frequencies. The inductance value remains functionally equivalent for power line filtering applications.
