Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELJ-QF36NJF is determined by the following critical parameters:

• Inductance Value: Must be 36 nH with ±5% tolerance to maintain circuit performance
• Package / Case: Must be 0402 (1005 Metric) for PCB footprint compatibility
• Shielding Type: Must be unshielded to match electromagnetic characteristics
• Core Material: Must be ceramic to ensure consistent performance across frequency ranges
• Current Rating: Must meet or exceed 160 mA to support circuit current requirements
• DC Resistance: Must not exceed 1.6 Ohm to maintain acceptable power dissipation limits

The MLG1005S36NJTD25 from TDK Corporation meets all substitution criteria, offering improved specifications in current rating and DC resistance while maintaining identical inductance, tolerance, package, and core material characteristics.

Engineering Selection Recommendations

The MLG1005S36NJTD25 is the qualified substitute for the obsolete ELJ-QF36NJF. This substitution is supported by:

• Identical inductance value and tolerance specification
• Identical package and physical dimensions for direct PCB compatibility
• Improved current rating (250 mA vs. 160 mA) providing design margin
• Lower DC resistance (1 Ohm Max vs. 1.6 Ohm Max) reducing power dissipation
• Active product status ensuring long-term availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C)
• AEC-Q200 automotive qualification and ROHS3 compliance

Frequently Asked Questions (FAQ)

Q: Can the MLG1005S36NJTD25 be used as a direct replacement for the ELJ-QF36NJF?

A: Yes. Both components share identical inductance (36 nH), tolerance (±5%), package (0402 / 1005 Metric), physical dimensions, and core material (ceramic). The substitute meets or exceeds all electrical requirements of the original part.

Q: What are the advantages of using the MLG1005S36NJTD25 over the obsolete ELJ-QF36NJF?

A: The TDK substitute offers higher current rating (250 mA vs. 160 mA), lower DC resistance (1 Ohm Max vs. 1.6 Ohm Max), extended temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), active product status, and AEC-Q200 qualification.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts are unshielded multilayer ceramic inductors in identical 0402 packages with matching physical dimensions and mounting requirements.

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

A: The ELJ-QF36NJF has a maximum DC resistance of 1.6 Ohm, while the MLG1005S36NJTD25 has a maximum of 1 Ohm. The lower resistance of the substitute reduces power dissipation in the circuit.

Q: Does the substitute part have better temperature performance?

A: Yes. The MLG1005S36NJTD25 operates from -55°C to 125°C, compared to the original part's -40°C to 85°C range, providing extended thermal operating margins.
