108R-823JS Equivalent & Substitute Parts Reference

Part Overview

The Delevan 108R-823JS is an 82 µH unshielded surface mount inductor rated for 30 mA with a maximum DC resistance (DCR) of 28 Ohm. It features an iron core, mounting dimensions of 2.54mm x 2.54mm, and a height of 1.91mm. The part is delivered in tape & reel (TR) packaging and is specified for operation from -55°C to 125°C. The 108R-823JS status is “Obsolete,” requiring identification of substitute or equivalent inductor models to ensure continued BOM support and manufacturability.

Substitute Part Grouping Explanation

Equivalent and substitute inductor models are matched strictly by:

Inductance value
Tolerance
Current rating
Maximum DC resistance
Shielding status
Mounting type
Package size/dimensions
Maximum seated height
Operating temperature range
RoHS and REACH environmental compliance
Moisture Sensitivity Level (MSL)

All substitute parts in this reference meet these primary criteria within the specified tolerances.

Engineering Selection Recommendations

The Delevan 108R-823JS is designated obsolete. Any substitute device must match or exceed the RoHS compliance and MSL 1 (Unlimited) solder profile, and meet relevant REACH regulations. Substitute component selection should confirm RoHS3 compliance. Variations in REACH status should be evaluated per application requirements, as the original is REACH Unaffected and the substitute NLV25T-820J-EF is REACH Affected. Product status of the substitute must be "Active" or equivalent, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: How are substitute inductors determined for obsolete models like the Delevan 108R-823JS?
A: Substitutes are selected by matching inductance, tolerance, current rating, DC resistance, shielding, mounting type, mechanical dimensions, seated height, operating temperature range, and compliance with RoHS and REACH regulations.

Q: Is the footprint of the TDK NLV25T-820J-EF compatible with 108R-823JS?
A: Both are surface-mount inductors with closely matching body sizes and height. The TDK part uses the 1008 (2520 Metric) package, with minor variations in dimensions.

Q: Do both parts offer the same environmental and soldering reliability?
A: Both the Delevan 108R-823JS and TDK NLV25T-820J-EF are rated MSL 1 (Unlimited) and ROHS3 Compliant. REACH status differs and may require specific review.

Q: Can substitute inductors be used directly in all applications where 108R-823JS was specified?
A: Substitute inductors listed adhere to the key electrical, mechanical, and environmental parameters. Application-specific assessment is required for PCB footprint and compliance documentation.
