Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S3483R-470M is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value of 47 µH
• Current rating of 600 mA or greater
• DC resistance within acceptable operating limits (≤360 mOhm maximum for functional compatibility)
• Ferrite core material with shielding configuration

Mechanical Compatibility Requirements:

• Surface mount package type
• Nonstandard form factor suitable for equivalent PCB footprint integration
• Physical dimensions permitting board-level placement

Compliance Requirements:

• ROHS3 compliance certification
• REACH unaffected status
• EAR99 export classification

The SRR0604-470KL from Bourns Inc. meets these substitution criteria through matching inductance, current rating, core material, shielding, and compliance certifications. Dimensional and resistance variations remain within acceptable engineering tolerances for this component category.

Engineering Selection Recommendations

Primary Part: S3483R-470M

The S3483R-470M is the specified component and remains the first choice when available. It provides the lowest profile height (3.50 mm seated) and meets all electrical and compliance requirements. Current inventory of 828 pieces supports immediate procurement.

Substitute Part: SRR0604-470KL

The SRR0604-470KL from Bourns Inc. is a qualified substitute when S3483R-470M availability is constrained. Selection of this alternative is based on:

• Matching 47 µH inductance value
• Identical 600 mA current rating
• DC resistance of 360 mOhm, within 10 mOhm of the primary part specification
• Ferrite core with shielding configuration
• ROHS3 compliance and REACH unaffected status
• Active product status with 2400 pieces in stock

Dimensional Considerations:

The SRR0604-470KL has a smaller lateral footprint (6.50mm vs 7.20mm) but greater seated height (4.80mm vs 3.50mm). PCB layout verification is required to confirm clearance compatibility in height-constrained applications. The smaller lateral dimensions may provide layout advantages in space-restricted designs.

Compliance and Regulatory:

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. No regulatory barriers exist for substitution in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the SRR0604-470KL directly replace the S3483R-470M on an existing PCB?

A: Electrical substitution is valid based on matching inductance, current rating, and DC resistance specifications. However, physical footprint differences require PCB layout verification. The SRR0604-470KL has a smaller lateral footprint (6.50mm vs 7.20mm) but greater height (4.80mm vs 3.50mm). Pad pattern compatibility and clearance to adjacent components must be confirmed before board-level implementation.

Q: What is the significance of the ±20% tolerance on the S3483R-470M versus ±10% on the SRR0604-470KL?

A: The SRR0604-470KL provides tighter inductance tolerance control. For applications requiring strict inductance accuracy, the Bourns part offers superior performance. For applications with ±20% tolerance acceptance, both parts are functionally equivalent.

Q: Are there temperature range differences between these parts?

A: The S3483R-470M operates from -20°C to 85°C, while the SRR0604-470KL operates from -40°C to 125°C. For applications requiring extended low-temperature operation below -20°C or sustained operation above 85°C, the Bourns substitute provides broader environmental capability.

Q: What is the DC resistance difference between these inductors?

A: The S3483R-470M specifies 350 mOhm maximum DCR, while the SRR0604-470KL specifies 360 mOhm maximum. This 10 mOhm difference represents approximately 2.9% variance and remains within acceptable engineering tolerance for this inductor category. Both values support equivalent power dissipation performance at 600 mA rated current.

Q: Does the SRR0604-470KL saturation current specification affect substitution?

A: The SRR0604-470KL specifies 800 mA saturation current, providing additional margin above the 600 mA rated current. This specification is not provided for the S3483R-470M. The saturation current specification on the Bourns part indicates additional design margin but does not affect substitution validity for applications operating at or below 600 mA.

Q: Are both parts suitable for high-frequency applications?

A: The S3483R-470M inductance is tested at 100 kHz. The SRR0604-470KL provides additional frequency characterization with Q of 15 at 2.52 MHz and self-resonant frequency of 18 MHz. For applications requiring frequency response data above 100 kHz, the Bourns part provides more complete specifications.

Q: What packaging format is used for both parts?

A: Both the S3483R-470M and SRR0604-470KL are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage or handling.
