S3483R-101M Equivalent & Substitute Parts

Part Overview

The S3483R-101M is a 100 µH shielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 450 mA continuous current with a maximum DC resistance of 790 mOhm. This surface mount component operates across the temperature range of -20°C to 85°C and is classified as Active product status with ROHS3 compliance.

Substitute parts are identified when equivalent inductance values, compatible current ratings, and matching shielding characteristics are maintained within acceptable tolerance and performance parameters. The S3483R-101M has been identified with one qualified substitute in the Bourns Inc. SRR0604 series.

Substitute Part Grouping Explanation

Substitution eligibility for the S3483R-101M is determined by the following critical parameters:

Primary Matching Criteria:

Inductance value: 100 µH (exact match required)
Core type: Ferrite drum core, wirewound construction
Shielding: Shielded configuration
Mounting: Surface mount, nonstandard package
Current handling capability: Minimum 400 mA (substitute must support primary part's 450 mA rating or operate within acceptable derating)
DC resistance: Maximum 790 mOhm (substitute DCR of 650 mOhm is acceptable as lower resistance)

Compliance Requirements:

RoHS3 compliance mandatory
REACH unaffected status required
ECCN EAR99 classification

The SRR0604-101KL from Bourns Inc. satisfies all primary matching criteria with equivalent inductance, ferrite core construction, shielded configuration, and surface mount design. The substitute exhibits lower DC resistance (650 mOhm vs. 790 mOhm maximum) and tighter tolerance (±10% vs. ±20%), representing improved electrical performance characteristics.

Engineering Selection Recommendations

S3483R-101M Selection Criteria:

Applications requiring continuous current operation at or above 450 mA
Designs constrained by maximum height of 3.50mm
Operating temperature range limited to -20°C to 85°C
Existing inventory availability (847 pcs in stock)

SRR0604-101KL Selection Criteria:

Applications with continuous current requirements at or below 400 mA
Designs benefiting from extended operating temperature range (-40°C to 125°C)
Circuits where lower DC resistance (650 mOhm) reduces power dissipation
PCB layouts accommodating increased height of 4.80mm
Designs requiring tighter inductance tolerance (±10%)
Higher inventory availability (15,835 pcs in stock)

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Selection between these components depends on application current requirements, thermal environment, and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can the SRR0604-101KL replace the S3483R-101M in all applications?

A: Substitution is valid only when application current does not exceed 400 mA continuous. The S3483R-101M is rated for 450 mA; the SRR0604-101KL is rated for 400 mA. If your circuit draws current between 400 mA and 450 mA, the substitute is not appropriate without thermal derating analysis.

Q: What are the physical differences between these inductors?

A: The S3483R-101M measures 7.20mm × 7.20mm with 3.50mm maximum height. The SRR0604-101KL measures 6.50mm × 6.50mm with 4.80mm maximum height. The substitute is smaller in footprint but taller. Verify PCB layout compatibility before substitution.

Q: Do both parts have identical electrical performance?

A: Both parts provide 100 µH inductance with ferrite shielded drum core construction. The SRR0604-101KL exhibits lower DC resistance (650 mOhm vs. 790 mOhm maximum) and tighter tolerance (±10% vs. ±20%), representing improved performance. The S3483R-101M supports higher continuous current (450 mA vs. 400 mA).

Q: Are there temperature range considerations for substitution?

A: The S3483R-101M operates from -20°C to 85°C. The SRR0604-101KL operates from -40°C to 125°C. If your application requires operation below -20°C or above 85°C, only the SRR0604-101KL is suitable.

Q: What is the tolerance difference impact?

A: The S3483R-101M has ±20% inductance tolerance; the SRR0604-101KL has ±10% tolerance. For circuits requiring tighter inductance control, the substitute provides superior specification compliance.

Q: Are both parts RoHS compliant?

A: Yes. Both the S3483R-101M and SRR0604-101KL are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.
