Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3483R-102M is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Inductance value must equal 1 mH at 100 kHz test frequency
• Inductance tolerance must accommodate ±20% specification
• DC resistance must not exceed 5.6Ohm maximum
• Current rating must support minimum 150 mA operation

Mechanical Compatibility Criteria:

• Mounting type must be Surface Mount
• Package configuration must be compatible with 2-SMD footprint dimensions (7.20mm x 7.20mm maximum length/width, 3.50mm maximum height)
• Core material must be ferrite-based drum core wirewound construction

Environmental & Compliance Criteria:

• Operating temperature range must encompass -20°C to 85°C minimum
• RoHS3 compliance required
• MSL rating must be 1 (Unlimited)

The substitute part SLF7032T-102MR13-2PF meets all electrical parameters within tolerance. Mechanical dimensions remain within acceptable limits. However, this substitute introduces shielding (shielded vs. unshielded), operates across an extended temperature range (-40°C to 105°C), and carries a "Not For New Designs" product status from TDK Corporation.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (3483R-102M): The 3483R-102M maintains active product status from API Delevan Inc. and is recommended for new designs requiring unshielded inductor operation within the specified -20°C to 85°C temperature window. This component is suitable for applications where electromagnetic shielding is not required and where the 150 mA current rating satisfies circuit demands.

Substitute Component (SLF7032T-102MR13-2PF): The SLF7032T-102MR13-2PF from TDK Corporation carries "Not For New Designs" status, indicating the manufacturer has discontinued active development for this part. This substitute is electrically compatible within specified tolerances but operates at a reduced current rating of 130 mA. The shielded configuration provides electromagnetic containment not present in the primary component. The extended operating temperature range (-40°C to 105°C) exceeds primary component specifications. This substitute is suitable only for legacy design support or applications where current demand does not exceed 130 mA and shielding characteristics are acceptable.

Compliance Status: Both components maintain ROHS3 compliance, MSL 1 rating, and EAR99 export classification, ensuring regulatory compatibility across standard applications.

Frequently Asked Questions (FAQ)

Q: Can the SLF7032T-102MR13-2PF directly replace the 3483R-102M in existing designs?

A: Electrical substitution is possible within the specified parameter tolerances. The substitute maintains 1 mH inductance at ±20% tolerance and operates at 100 kHz test frequency. However, the current rating reduces from 150 mA to 130 mA, requiring circuit verification that maximum operating current does not exceed 130 mA. The shielded configuration differs from the unshielded primary component, which may affect electromagnetic coupling in sensitive applications. Mechanical dimensions are slightly smaller (7.00mm vs. 7.20mm), which is compatible with standard 2-SMD footprints.

Q: What are the key differences between these inductors?

A: The primary differences are: (1) Current Rating: 3483R-102M supports 150 mA versus 130 mA for SLF7032T-102MR13-2PF; (2) Shielding: 3483R-102M is unshielded while SLF7032T-102MR13-2PF is shielded; (3) Product Status: 3483R-102M is active while SLF7032T-102MR13-2PF is not for new designs; (4) Operating Temperature: 3483R-102M operates -20°C to 85°C while SLF7032T-102MR13-2PF operates -40°C to 105°C; (5) DC Resistance: 3483R-102M maximum 5.6Ohm versus 5.736Ohm for SLF7032T-102MR13-2PF.

Q: Are there packaging differences between these parts?

A: The 3483R-102M is supplied in Tape & Reel (TR) packaging, while the SLF7032T-102MR13-2PF is supplied in Cut Tape (CT) and Digi-Reel® packaging. Both are surface mount components with 2-SMD package configurations. Mechanical dimensions are comparable: 3483R-102M measures 7.20mm x 7.20mm x 3.50mm (max height) while SLF7032T-102MR13-2PF measures 7.00mm x 7.00mm x 3.40mm (max height). Both dimensions are compatible with standard SMD assembly equipment and PCB footprints designed for 2-SMD inductors.

Q: What compliance certifications apply to both components?

A: Both the 3483R-102M and SLF7032T-102MR13-2PF maintain ROHS3 compliance, indicating restriction of hazardous substances per EU Directive 2011/65/EU. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, permitting unlimited shelf life under controlled storage conditions. Both are classified as EAR99 for export purposes and fall under HTSUS code 8504.50 for electrical apparatus. REACH status is unaffected for both components.

Q: When should the substitute part be used?

A: The SLF7032T-102MR13-2PF substitute should be considered only when the primary 3483R-102M component is unavailable due to supply constraints or extended lead times. The substitute is suitable for applications where: (1) circuit maximum current does not exceed 130 mA; (2) shielded inductor operation is acceptable or beneficial; (3) extended temperature operation (-40°C to 105°C) is required; (4) legacy design support is necessary. The "Not For New Designs" status from TDK indicates this component should not be selected for new product development.
