ELJ-PF5N6DFB Equivalent & Substitute Parts

Part Overview

The ELJ-PF5N6DFB is a 5.6 nH unshielded drum core wirewound inductor manufactured by Panasonic Electronic Components. This surface mount component is rated for 1.2 A maximum current with 120mOhm DC resistance in a 0402 (1005 Metric) package. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring this inductance value and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELJ-PF5N6DFB is determined by the following critical parameters:

• Inductance Value: Must be 5.6 nH to maintain circuit function
• Package / Case: Must be 0402 (1005 Metric) for PCB compatibility
• Mounting Type: Must be Surface Mount
• Core Type: Must be Drum Core, Wirewound
• Shielding: Must be Unshielded

The AISC-0402HP-5N6J-T from Abracon LLC meets all these core requirements. While this substitute exhibits improved electrical performance characteristics (higher current rating, lower DCR, higher Q factor), it maintains functional equivalence through identical inductance, package, and mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

The AISC-0402HP-5N6J-T is a direct functional substitute for the obsolete ELJ-PF5N6DFB. Both components share identical inductance values, package specifications, and mounting configurations required for PCB-level compatibility.

The Abracon part offers superior performance margins: increased current rating (1.5 A vs 1.2 A), reduced DC resistance (55mOhm vs 120mOhm), and extended operating temperature range (-40°C to 125°C vs -40°C to 85°C). The substitute maintains REACH compliance and provides ROHS3 certification with improved moisture sensitivity rating (MSL 1 vs MSL 2).

Selection of the AISC-0402HP-5N6J-T is appropriate for applications where the original Panasonic part is no longer available. The active product status and enhanced specifications support long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the AISC-0402HP-5N6J-T replace the ELJ-PF5N6DFB in existing designs?

A: Yes. Both inductors share the same 5.6 nH inductance value, 0402 (1005 Metric) package, and surface mount configuration. PCB layout and footprint compatibility are maintained.

Q: What is the significance of the different inductance tolerances?

A: The ELJ-PF5N6DFB specifies ±0.3nH tolerance, while the AISC-0402HP-5N6J-T specifies ±5% tolerance. For a 5.6 nH component, ±5% equals approximately ±0.28nH, making the tolerances functionally equivalent for most applications.

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

A: The AISC-0402HP-5N6J-T exhibits 55mOhm maximum DCR compared to 120mOhm for the original part. Lower DCR reduces resistive losses and heat generation, representing an improvement for the application. This change does not compromise compatibility.

Q: Are there packaging differences between these parts?

A: Both components are supplied in 0402 (1005 Metric) surface mount packages with identical footprints. The Abracon part is available in Tape & Reel (TR) packaging, while the Panasonic part packaging format is not specified in available data.

Q: What is the impact of the extended temperature range in the substitute?

A: The AISC-0402HP-5N6J-T operates from -40°C to 125°C, compared to -40°C to 85°C for the original. The extended upper temperature limit provides additional operational margin and is suitable for applications requiring higher temperature performance.
