ELJ-QF6N2DF Equivalent & Substitute Parts

Part Overview

The ELJ-QF6N2DF is a 6.2 nH unshielded multilayer ceramic inductor manufactured by Panasonic Electronic Components. This component is rated for 330 mA maximum current with a DC resistance of 250 mOhm maximum, housed in a 0402 (1005 Metric) surface mount package. The part is currently obsolete, necessitating identification of equivalent alternatives that maintain functional compatibility for new designs or production continuity.

Substitute Part Grouping Explanation

Substitution of the ELJ-QF6N2DF is determined by strict equivalence in the following parameters:

• Inductance Value: 6.2 nH (with tolerance ±0.3 nH)
• Package / Case: 0402 (1005 Metric) surface mount
• DC Resistance: 250 mOhm maximum
• Shielding Configuration: Unshielded
• Core Material: Ceramic

The substitute part MLG1005S6N2ST000 meets all these criteria. While the substitute offers a higher current rating (600 mA versus 330 mA) and an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C), these represent improvements that do not compromise compatibility. The identical inductance value, tolerance, package dimensions, and DC resistance ensure functional equivalence in circuit applications.

Engineering Selection Recommendations

The MLG1005S6N2ST000 (TDK Corporation) is the direct equivalent substitute for the obsolete ELJ-QF6N2DF. Selection of this substitute is supported by:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain REACH Unaffected status and equivalent MSL ratings, with the substitute additionally certified as ROHS3 Compliant.
• Functional Equivalence: Identical inductance, tolerance, DC resistance, and package specifications ensure drop-in compatibility without circuit redesign.
• Enhanced Performance Margin: The higher current rating and extended temperature range of the substitute provide additional operational headroom without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can MLG1005S6N2ST000 be used as a direct replacement for ELJ-QF6N2DF?

A: Yes. Both parts share identical inductance (6.2 nH), tolerance (±0.3 nH), DC resistance (250 mOhm max), and 0402 (1005 Metric) package dimensions. The substitute is functionally equivalent and compatible with existing PCB layouts and solder profiles.

Q: What are the differences between these two parts?

A: The primary differences are current rating (330 mA versus 600 mA), operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C), and product status (obsolete versus active). The substitute offers higher current capacity and broader temperature operation, both of which enhance design margins.

Q: Are there any compatibility concerns with the substitute?

A: No compatibility concerns exist. Identical package dimensions, inductance values, and DC resistance specifications ensure mechanical and electrical compatibility. The substitute's higher current rating and extended temperature range do not introduce any negative effects.

Q: Why is the original part obsolete?

A: The ELJ-QF6N2DF is listed as obsolete by Panasonic. The TDK MLG1005S6N2ST000 remains in active production and is the recommended alternative for new designs and production continuity.

Q: Are both parts RoHS compliant?

A: The substitute MLG1005S6N2ST000 is ROHS3 Compliant. Both parts maintain REACH Unaffected status and equivalent Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).
