ELJ-NDR10KF Equivalent & Substitute Parts

Part Overview

The ELJ-NDR10KF is a 100 nH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 285 mA with a maximum DC resistance of 860mOhm in a 0805 (2012 Metric) surface mount package. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELJ-NDR10KF is determined by the following critical parameters:

• Inductance Value: 100 nH (exact match required)
• Current Rating: Minimum 285 mA (substitute must meet or exceed)
• DC Resistance: Maximum 860mOhm (substitute must not exceed)
• Package Compatibility: 0805 (2012 Metric) or equivalent footprint
• Mounting Type: Surface Mount
• Operating Temperature Range: Minimum -20°C ~ 85°C coverage
• Shielding: Unshielded configuration

The three substitute parts listed below satisfy these core electrical and mechanical requirements while offering improved specifications in certain parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing long-term availability compared to the obsolete ELJ-NDR10KF.

B82498F3101J000 (EPCOS - TDK Electronics) offers the lowest DC resistance at 280mOhm maximum, providing superior performance margin over the original 860mOhm specification. This part includes AEC-Q200 automotive qualification and supports the widest operating temperature range (-55°C ~ 125°C), making it suitable for demanding applications.

LRW0805WKR10GG001E (Johanson Technology Inc.) maintains the original 0805 (2012 Metric) package designation and matches the ±10% tolerance of the ELJ-NDR10KF. It provides the highest current rating at 500 mA with 430mOhm DC resistance and ROHS3 compliance.

7447602C (Würth Elektronik) delivers 400 mA current rating with 460mOhm DC resistance and extended operating temperature range (-40°C ~ 125°C). All three substitutes exceed the original current rating requirement of 285 mA and provide DC resistance values well within acceptable limits.

Frequently Asked Questions (FAQ)

Q: Can the ELJ-NDR10KF be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts meet the core electrical requirements: 100 nH inductance, minimum 285 mA current rating, and DC resistance not exceeding 860mOhm. All maintain unshielded configuration and surface mount compatibility.

Q: What is the difference between the package designations "0805 (2012 Metric)" and "Nonstandard"?

A: The 7447602C and B82498F3101J000 are listed with nonstandard package designations but use 0805 supplier device packages. The LRW0805WKR10GG001E and original ELJ-NDR10KF use standard 0805 (2012 Metric) designations. Physical footprint compatibility should be verified during PCB layout review.

Q: Which substitute offers the best performance improvement?

A: B82498F3101J000 provides the lowest DC resistance (280mOhm) and widest operating temperature range (-55°C ~ 125°C), with AEC-Q200 qualification for automotive applications.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original ELJ-NDR10KF does not specify RoHS status.

Q: What is the tolerance difference between substitutes?

A: The 7447602C and B82498F3101J000 offer ±5% tolerance, providing tighter inductance control compared to the ±10% tolerance of the ELJ-NDR10KF and LRW0805WKR10GG001E.

Q: Do all substitutes have unlimited moisture sensitivity?

A: Yes. All parts, including the original ELJ-NDR10KF, are classified as MSL 1 (Unlimited), requiring no special moisture handling during storage or assembly.
