Substitute Part Grouping Explanation

Substitution of the SCB63C-820 is determined by the following critical parameters:

• Inductance Value: Must be 82 µH to maintain circuit functionality
• Shielding Type: Must be shielded to preserve electromagnetic isolation characteristics
• Mounting Type: Must be surface mount to ensure PCB compatibility
• Physical Footprint: Must maintain 6.20mm x 6.20mm base dimensions for board layout compatibility
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Regulatory Compliance: Must maintain ROHS3 and REACH compliance status

The SCRH5D18-820 meets all substitution criteria. While it exhibits higher DC resistance (978 mOhm vs. 572 mOhm) and lower current rating (550 mA vs. 700 mA), these parameters remain within acceptable tolerance for equivalent functionality in applications where the SCB63C-820 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The SCRH5D18-820 is the designated manufacturer substitute for the obsolete SCB63C-820. Both components are manufactured by Signal Transformer and maintain identical inductance values, shielding characteristics, and physical footprints. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The SCRH5D18-820 features improved saturation current performance (410 mA vs. 250 mA) and a reduced seated height (2.00mm vs. 3.00mm), providing potential advantages in space-constrained designs.

Selection of the SCRH5D18-820 is appropriate for applications where the SCB63C-820 was originally specified, provided that the circuit design accommodates the higher DC resistance and lower continuous current rating of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the SCRH5D18-820 be used as a direct replacement for the SCB63C-820?

A: Yes. Both parts share identical inductance values (82 µH), shielding type (shielded), mounting configuration (surface mount), and physical footprint (6.20mm x 6.20mm). The SCRH5D18-820 is the manufacturer-designated substitute.

Q: What are the key differences between these parts?

A: The primary differences are DC resistance (572 mOhm vs. 978 mOhm), continuous current rating (700 mA vs. 550 mA), inductance tolerance (±20% vs. ±30%), and seated height (3.00mm vs. 2.00mm). The SCRH5D18-820 also features higher saturation current (410 mA vs. 250 mA).

Q: Will the higher DC resistance of the SCRH5D18-820 affect circuit performance?

A: DC resistance affects power dissipation and voltage drop across the inductor. Applications operating at or near the 700 mA rating of the original part require evaluation to confirm the 550 mA rating and higher resistance of the substitute are acceptable.

Q: Are there packaging differences between these parts?

A: The SCB63C-820 uses nonstandard packaging, while the SCRH5D18-820 is supplied in Tape & Reel (TR) format. Both maintain identical physical dimensions and surface mount compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SCB63C-820 and SCRH5D18-820 are ROHS3 compliant, REACH unaffected, and rated for -40°C to 125°C operation.
