Substitute Part Grouping Explanation

Substitute components are grouped based on the following critical electrical and mechanical parameters that define functional equivalence:

Primary Matching Criteria:

• Inductance: 100 µH ±10%
• Current Rating: Minimum 970 mA or above
• DC Resistance: Maximum 350 mOhm or below
• Mounting Type: Surface Mount
• Shielding: Unshielded
• Frequency Test Standard: 1 kHz

The substitute parts SDR1006-101KL and 22R104MC satisfy these primary criteria with the following distinctions based on provided specifications.

Parameter Comparison

Engineering Selection Recommendations

SDR1006-101KL (Bourns Inc.) is the primary electrical substitute for PD105R-104K. Both components share identical inductance, current rating, and DC resistance specifications. The SDR1006-101KL maintains the same ferrite drum core construction and operating temperature range of -40°C ~ 125°C, overlapping the original component's upper operating limit. Both components are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring environmental compliance and reliability in storage and manufacturing processes.

22R104MC (Murata Power Solutions Inc.) is a secondary electrical substitute that meets the primary inductance specification of 100 µH ±10% and shielding requirements. However, the current rating of 800 mA is below the original 970 mA specification, and the DC resistance of 390 mOhm Max exceeds the 350 mOhm maximum of the original component. The operating temperature range of -40°C ~ 85°C is restricted compared to the original part. The 22R104MC is ROHS3 compliant with MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can SDR1006-101KL directly replace PD105R-104K in all applications? A: The SDR1006-101KL matches all critical electrical parameters—inductance, current rating, and DC resistance—and maintains equivalent operating temperature coverage from -40°C ~ 125°C. Physical dimensions differ slightly (width 9.80mm vs 8.79mm for the original), requiring PCB layout verification for pin-to-component clearances. Both components share ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental performance.

Q: Is 22R104MC suitable as a replacement? A: The 22R104MC satisfies the inductance and shielding requirements; however, the 800 mA current rating is 170 mA below the original specification, and the 390 mOhm maximum DCR exceeds the 350 mOhm limit by 40 mOhm. Application suitability depends on actual circuit current demands. If the circuit requires the full 970 mA rating or lower resistance, 22R104MC is not an equivalent substitute.

Q: What are the primary differences in physical dimensions? A: SDR1006-101KL measures 9.80mm x 9.80mm length and width with 5.80mm seated height, compared to PD105R-104K at 9.80mm x 8.79mm with 5.40mm seated height. The 22R104MC is significantly smaller at 7.80mm x 7.00mm with 7.90mm seated height. These dimensional differences necessitate PCB layout review to confirm component placement compatibility and spacing with adjacent circuitry.

Q: Are all substitute parts actively manufactured? A: Both SDR1006-101KL and 22R104MC carry active product status from Bourns Inc. and Murata Power Solutions Inc., respectively, with published inventory availability. The original PD105R-104K is obsolete, making active substitutes necessary for new production and design revisions.

Q: What compliance certifications apply to these components? A: All listed components—PD105R-104K, SDR1006-101KL, and 22R104MC—are ROHS3 compliant and REACH unaffected. All components carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and manufacturing. ECCN classification is EAR99 for all parts.
