Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S3483R-6R8M are qualified based on the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 6.8 µH (exact match required)
• Inductance tolerance: ±20% (matching tolerance band)
• Core type: Ferrite shielded drum core wirewound construction
• Mounting: Surface mount configuration
• DC resistance: 55 mOhm maximum specification
• Compliance: ROHS3 compliant, REACH unaffected status

Secondary Compatibility Factors:

• Current rating: Minimum 1.76 A (equal or higher acceptable)
• Operating temperature: Overlap with -20°C to 85°C range
• Package classification: Nonstandard surface mount
• Moisture sensitivity: MSL 1 (unlimited)

The identified substitutes meet these core electrical and mechanical requirements while maintaining functional equivalence for the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

B82472G4682M000 (EPCOS - TDK Electronics)

This substitute provides direct electrical equivalence with identical 6.8 µH inductance, ±20% tolerance, and 55 mOhm maximum DC resistance. The current rating of 2.05 A exceeds the S3483R-6R8M requirement of 1.76 A, providing operational margin. Extended operating temperature range (-55°C to 125°C) accommodates broader environmental conditions. ROHS3 compliance and MSL 1 rating match the original specification. Physical dimensions (7.30mm x 7.30mm x 3.50mm) are comparable to the original (7.20mm x 7.20mm x 3.50mm). This part is suitable for direct substitution in applications where the extended temperature range does not create thermal management conflicts.

SRR0604-6R8ML (Bourns Inc.)

This substitute maintains 6.8 µH inductance and ±20% tolerance with ferrite shielded drum core construction. Current rating of 1.6 A is marginally below the S3483R-6R8M specification of 1.76 A; applications operating near maximum current should be evaluated. DC resistance of 70 mOhm exceeds the 55 mOhm maximum of the original part, resulting in higher power dissipation. Operating temperature range (-40°C to 125°C) extends below the original minimum of -20°C. Physical dimensions (6.50mm x 6.50mm x 4.80mm) differ from the original, with reduced length and width but increased height. Corner terminal configuration requires PCB layout verification. ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for substitution in applications where the reduced current margin and increased DC resistance are acceptable, and PCB layout accommodates the corner terminal design and increased height.

Frequently Asked Questions (FAQ)

Q: Can B82472G4682M000 be used as a direct replacement for S3483R-6R8M?

A: Yes. Both parts share identical 6.8 µH inductance, ±20% tolerance, and 55 mOhm maximum DC resistance. The B82472G4682M000 provides higher current rating (2.05 A vs. 1.76 A) and extended temperature range (-55°C to 125°C vs. -20°C to 85°C). Physical dimensions are comparable. ROHS3 compliance and MSL 1 ratings match. Substitution is valid for applications within the original operating temperature range.

Q: What are the limitations of using SRR0604-6R8ML as a substitute?

A: The SRR0604-6R8ML has three key differences: (1) Current rating of 1.6 A is below the original 1.76 A specification, requiring evaluation for applications operating near maximum current; (2) DC resistance of 70 mOhm exceeds the 55 mOhm maximum, increasing power dissipation by approximately 27%; (3) Physical dimensions differ, with increased height (4.80mm vs. 3.50mm) and corner terminal configuration requiring PCB layout verification. Substitution is valid only when these parameters are acceptable for the application.

Q: Are all three parts ROHS3 compliant?

A: Yes. S3483R-6R8M, B82472G4682M000, and SRR0604-6R8ML are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level and REACH unaffected status.

Q: What is the primary difference in operating temperature ranges?

A: The S3483R-6R8M operates from -20°C to 85°C. The B82472G4682M000 extends to -55°C to 125°C, and the SRR0604-6R8ML operates from -40°C to 125°C. Both substitutes support the original temperature range and provide extended capability at lower and higher temperatures.

Q: Does the corner terminal configuration of SRR0604-6R8ML affect PCB compatibility?

A: Yes. The SRR0604-6R8ML features corner terminals, which differs from the standard terminal configuration of the S3483R-6R8M. PCB layout and footprint design must be verified to accommodate this terminal arrangement. Additionally, the increased height (4.80mm vs. 3.50mm) may affect component clearance in space-constrained applications.

Q: Which substitute is recommended for high-current applications?

A: The B82472G4682M000 is recommended for high-current applications, providing 2.05 A current rating compared to the original 1.76 A specification. This part maintains identical DC resistance and inductance specifications while offering operational margin for current-limited designs.
