PD104R-823K Equivalent & Substitute Parts Reference

Part Overview

The Delevan PD104R-823K is an active, surface-mount, unshielded drum core, wirewound inductor featuring 82 µH inductance, a maximum current rating of 850 mA, and a maximum DC resistance of 250 mOhm. Its nonstandard SMD package measures 9.80 mm × 8.79 mm with a maximum seated height of 4.00 mm. This inductor is ROHS3 compliant and classified under MSL 1 with REACH unaffected status. When current market conditions or supply limitations require, sourcing compatible alternative inductors with closely matching electrical and mechanical properties is essential for maintaining assembly continuity.

• Shielding: Unshielded
• Core Material: Ferrite
• Type: Drum Core, Wirewound
• Mounting: Surface Mount
• Package: Nonstandard SMD, with closely matching dimensions
• Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

Selection between PD104R-823K and SDR1006-820KL can be performed based on active part status and equivalent compliance certifications. Both inductors are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited), meeting current regulatory and handling requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the PD104R-823K?
A1: Key parameters include inductance (82 µH), tolerance (±10%), current rating (≥850 mA), DC resistance (≤250 mOhm), package/size compatibility, mounting type (SMD), core material (ferrite), shielding (unshielded), and compliance with ROHS3/REACH.

Q2: Is the SDR1006-820KL an exact match for size and height requirements?
A2: Both inductors share the same length (9.80 mm), but SDR1006-820KL is wider (9.80 mm vs. 8.79 mm) and taller (5.80 mm vs. 4.00 mm). Mechanical fit should be verified against board layout tolerances.

Q3: Are both PD104R-823K and SDR1006-820KL compliant with lead-free and environmental standards?
A3: Both parts are ROHS3 compliant and REACH unaffected.

Q4: Are the mounting types and construction equivalent?
A4: Both parts are surface mount, unshielded drum core, wirewound inductors using ferrite material.

Q5: Do both inductors offer the same tolerance and maximum DCR?
A5: Yes, both are rated at ±10% tolerance with a maximum DC resistance of 250 mOhm.
