S3483R-680M

Part Overview

The S3483R-680M is a 68 µH shielded drum core, wirewound inductor manufactured by API Delevan Inc., rated for 500 mA continuous current with a maximum DC resistance of 520 mOhm. The component is currently active in production and ROHS3 compliant. Alternative components may be required due to inventory constraints, regional availability, or application-specific performance requirements that demand enhanced specifications such as tighter inductance tolerance, higher saturation current, or extended operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

The SRR0604-680KL from Bourns Inc. qualifies as a substitute for the S3483R-680M based on the following critical electrical and mechanical alignment:

Matching Parameters:

• Inductance: 68 µH (identical)
• Current Rating: 500 mA (identical)
• DC Resistance: 520 mOhm Max (identical)
• Core Material: Ferrite, Shielded Drum Core (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Packaging: Tape & Reel (identical)

Enhanced Specifications in Substitute: The SRR0604-680KL provides tighter inductance tolerance (±10% versus ±20%), higher saturation current (680 mA versus unspecified), wider operating temperature range (-40°C to 125°C versus -20°C to 85°C), and documented quality factor parameters. These enhancements do not affect backward compatibility with applications designed for the S3483R-680M.

Parameter Comparison

Engineering Selection Recommendations

Both components satisfy ROHS3 compliance and REACH unaffected status for regulatory applications. The S3483R-680M remains the primary selection for cost-optimized designs with standard operating conditions (-20°C to 85°C). The SRR0604-680KL serves as the qualified substitute for applications requiring enhanced performance margins, specifically tighter inductance tolerance and extended temperature operation, or when API Delevan components are unavailable. Both components maintain identical electrical core specifications (inductance, current rating, DC resistance) and ferrite shielded drum core construction, ensuring functional interchangeability in standard circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the SRR0604-680KL replace the S3483R-680M in existing designs? A: Yes. Both components share identical inductance (68 µH), current rating (500 mA), DC resistance (520 mOhm), core type (ferrite shielded drum core), and mounting type (surface mount). The SRR0604-680KL offers tighter tolerance and extended temperature range, making it a direct functional substitute.

Q: What is the primary difference between these two inductors? A: The SRR0604-680KL features ±10% inductance tolerance compared to ±20% for the S3483R-680M, operates across a wider temperature range (-40°C to 125°C versus -20°C to 85°C), includes documented saturation current (680 mA), and incorporates corner terminal design. Electrical performance at rated specifications remains equivalent.

Q: Are there physical dimension differences that affect PCB layout? A: Yes. The S3483R-680M measures 0.283" L × 0.283" W × 0.138" H (7.20mm × 7.20mm × 3.50mm), while the SRR0604-680KL measures 0.256" L × 0.256" W × 0.189" H (6.50mm × 6.50mm × 4.80mm). The substitute is smaller in footprint but taller in height. PCB layout verification is required for mechanical fit.

Q: Do both parts meet RoHS requirements? A: Yes. Both the S3483R-680M and SRR0604-680KL are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for restricted substance applications.

Q: Which component should I select for high-temperature applications? A: The SRR0604-680KL is rated for operation up to 125°C, compared to 85°C maximum for the S3483R-680M. Select the SRR0604-680KL for applications exceeding 85°C ambient or component temperature.
