Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3483-560M is determined by the following critical parameters:

• Inductance Value: 56 µH (exact match required)
• Current Rating: Minimum 550 mA to maintain design specifications
• DC Resistance: Maximum 480 mOhm to ensure acceptable power dissipation
• Core Type: Ferrite drum core, wirewound construction
• Shielding Configuration: Unshielded
• Mounting: Surface mount technology

The SDR0603-560KL from Bourns Inc. meets these substitution criteria with equivalent inductance and compatible electrical characteristics within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The SDR0603-560KL serves as a functional substitute for the obsolete 3483-560M based on matching inductance value, ferrite core construction, and unshielded configuration. The substitute part offers improved compliance status as an active product with ROHS3 certification, compared to the non-compliant obsolete original.

Design considerations for substitution include the reduced current rating (480 mA versus 550 mA) and increased DC resistance (620 mOhm versus 480 mOhm maximum). These differences require circuit-level evaluation to confirm acceptable performance within the intended application. The substitute provides a wider operating temperature range (-40°C to 125°C) and tighter inductance tolerance (±10% versus ±20%), which may offer design advantages in temperature-sensitive or precision-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the SDR0603-560KL directly replace the 3483-560M in all applications?

A: Direct substitution requires verification that the application tolerates the reduced current rating (480 mA) and increased DC resistance (620 mOhm). If the circuit operates at or near the original 550 mA specification, alternative parts or circuit redesign may be necessary.

Q: What is the significance of the different inductance test frequencies?

A: The 3483-560M is tested at 100 kHz while the SDR0603-560KL is tested at 1 kHz. Both parts are specified at 56 µH, but frequency-dependent behavior may differ slightly in high-frequency applications. Circuit validation is recommended for frequency-sensitive designs.

Q: Does the improved RoHS compliance of the substitute affect electrical performance?

A: RoHS compliance relates to material composition and environmental impact, not electrical performance. The ROHS3 compliance of the SDR0603-560KL indicates adherence to current regulatory standards without altering the core electrical characteristics of the inductor.

Q: Are there physical package differences between these parts?

A: Both parts use nonstandard surface mount packages. The 3483-560M measures 0.287" × 0.287" × 0.138" (7.30mm × 7.30mm × 4.60mm), while the SDR0603-560KL measures 0.228" × 0.228" × 0.154" (5.80mm × 5.80mm × 3.90mm). Physical layout verification is required before substitution.

Q: What is the moisture sensitivity level for these inductors?

A: Both the 3483-560M and SDR0603-560KL carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
