SCB63C-560 Equivalent & Substitute Parts

Part Overview

The SCB63C-560 is a 56 µH shielded inductor rated for 900 mA continuous current with a maximum DC resistance of 401 mOhm, designed for surface mount applications in nonstandard packaging. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across the industrial temperature range of -40°C to 125°C and meets ROHS3 compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCB63C-560 is based on the following critical parameters that must remain compatible:

• Inductance Value: 56 µH (primary functional requirement)
• Shielding Type: Shielded (electromagnetic containment specification)
• Mounting Type: Surface Mount (assembly process compatibility)
• Physical Footprint: 6.20mm x 6.20mm (PCB layout constraint)
• Operating Temperature Range: -40°C to 125°C (environmental specification)
• Compliance Standards: ROHS3 Compliant (regulatory requirement)

The SCRH5D18-560 qualifies as a substitute based on matching inductance value, shielding, mounting type, footprint dimensions, temperature range, and compliance status. Variations in current rating, DC resistance, and saturation current are acceptable within the constraints of the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

The SCRH5D18-560 is available as an active product from Signal Transformer, providing supply continuity for the obsolete SCB63C-560. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Selection of the SCRH5D18-560 requires circuit-level validation where the substitute exhibits lower current rating (650 mA versus 900 mA) and higher DC resistance (665 mOhm versus 401 mOhm). The substitute's reduced height (2.00mm versus 3.00mm) may provide PCB layout advantages. The inductance tolerance specification widens from ±20% to ±30%, which must be evaluated against circuit performance margins.

Frequently Asked Questions (FAQ)

Q: Can the SCRH5D18-560 directly replace the SCB63C-560 in all applications?

A: Direct replacement is possible only when the application circuit operates at or below 650 mA continuous current and tolerates the increased DC resistance of 665 mOhm. The wider inductance tolerance of ±30% must be compatible with circuit design specifications.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The SCRH5D18-560 exhibits 264 mOhm additional DC resistance compared to the SCB63C-560. This increases resistive losses and heat dissipation in the inductor. Circuit thermal analysis is required to confirm acceptable operating conditions.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts share identical lateral dimensions of 6.20mm x 6.20mm, ensuring footprint compatibility. The SCRH5D18-560 is 1.00mm shorter in seated height, which may eliminate clearance constraints in compact designs.

Q: What packaging format is available for the substitute part?

A: The SCRH5D18-560 is supplied in Tape & Reel (TR) format, providing standard automated assembly compatibility. The original SCB63C-560 used nonstandard packaging.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SCB63C-560 and SCRH5D18-560 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.8000.
