Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN114-1.5-02 is determined by the following critical parameters: inductance value (6.8 mH), number of lines (2-line configuration), mounting type (through-hole), and pin configuration (4 PC Pin). Current rating and DC resistance must meet or exceed the original specifications to ensure thermal and electrical performance compatibility.

Two substitute parts are identified:

Direct Manufacturer Substitute (RN114-1.5-02-6M8): Same manufacturer (Schaffner EMC Inc.), identical inductance and line configuration, same mounting and package type. This part represents an active product variant with improved specifications.

Similar Manufacturer Substitute (LF2823NP-682): Alternative manufacturer (Sumida America Components Inc.) with matching inductance value and 2-line configuration. Physical dimensions and pin orientation differ, requiring mechanical compatibility verification.

Parameter Comparison

Engineering Selection Recommendations

RN114-1.5-02-6M8 (Recommended Primary Substitute): This part is the preferred substitute. It maintains identical electrical specifications (6.8 mH inductance, 2-line configuration, through-hole mounting, horizontal 4 PC Pin package) while offering improved performance characteristics: lower DC resistance (123mOhm vs. 130mOhm), higher AC voltage rating (300V vs. 250V), and active product status with ROHS3 compliance and expanded approval certifications (ENEC, UR, VDE). The part is currently in stock with 1604 units available.

LF2823NP-682 (Alternative Substitute): This part provides electrical compatibility with matching 6.8 mH inductance and 2-line configuration. However, it introduces mechanical and thermal differences: vertical pin orientation (vs. horizontal), larger physical dimensions (28.50mm x 28.50mm vs. 22.50mm x 21.50mm), higher DC resistance (230mOhm vs. 130mOhm), and higher current rating (1.6A vs. 1.5A). Missing specifications for voltage rating and operating temperature limit its suitability. This substitute is appropriate only when mechanical constraints permit the larger footprint and higher resistance is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can RN114-1.5-02-6M8 be used as a direct replacement for RN114-1.5-02?

A: Yes. Both parts share identical inductance (6.8 mH @ 10 kHz), current rating (1.5A), number of lines (2), mounting type (through-hole), and package configuration (horizontal, 4 PC Pin). The RN114-1.5-02-6M8 offers superior specifications with lower DC resistance and higher voltage rating, making it a direct upgrade.

Q: What are the mechanical differences between RN114-1.5-02 and LF2823NP-682?

A: The LF2823NP-682 differs in package orientation (vertical vs. horizontal) and physical dimensions (28.50mm x 28.50mm x 24.00mm vs. 22.50mm x 21.50mm x 14.60mm). PCB layout modifications are required for this substitute.

Q: Is LF2823NP-682 suitable for applications requiring 250V AC operation?

A: The LF2823NP-682 does not specify an AC voltage rating in the provided data. Verification with the manufacturer is necessary before selection for applications with defined voltage requirements.

Q: How does DC resistance affect component selection?

A: DC resistance determines power dissipation and thermal performance. The RN114-1.5-02-6M8 (123mOhm) dissipates less heat than the original (130mOhm) and significantly less than LF2823NP-682 (230mOhm). Higher resistance increases thermal load and may require thermal management considerations in space-constrained designs.

Q: What compliance certifications should be verified for safety-critical applications?

A: The RN114-1.5-02-6M8 carries ENEC, UR, and VDE approvals with ROHS3 compliance. The LF2823NP-682 specifies ROHS3 compliance only, with no approval agency certifications provided. For applications requiring specific safety standards, the RN114-1.5-02-6M8 is the appropriate choice.
