Substitute Part Grouping Explanation

Substitution of the SCB63C-220 is determined by the following critical parameters:

Inductance value must remain 22 µH to maintain circuit functionality. The substitute part SCRH5D28-220 matches this specification exactly.

Current rating requirements establish the minimum acceptable performance threshold. The SCB63C-220 is rated for 1.3 A continuous current. The substitute SCRH5D28-220 provides 1.7 A continuous current, exceeding the original specification and ensuring adequate thermal margin.

DC resistance (DCR) directly impacts power dissipation and thermal performance. The original part specifies 191 mOhm maximum; the substitute provides 122 mOhm maximum, representing improved efficiency characteristics.

Physical dimensions and mounting type must remain compatible with existing PCB layouts. Both parts share identical footprints (6.20 mm × 6.20 mm) and surface mount configuration.

Shielding characteristics must be preserved to maintain electromagnetic compatibility in the target application. Both parts are shielded inductors.

Operating temperature range and compliance certifications must meet or exceed the original specifications. Both parts operate across -40°C to 125°C and maintain ROHS3 compliance.

Engineering Selection Recommendations

The SCRH5D28-220 is the qualified substitute for the obsolete SCB63C-220. This recommendation is based on the following factors:

The substitute maintains identical inductance value (22 µH) and physical footprint, ensuring direct PCB compatibility without layout modifications.

The substitute provides superior electrical performance with 1.7 A continuous current rating versus 1.3 A, and reduced DC resistance of 122 mOhm maximum versus 191 mOhm maximum. These improvements result in lower power dissipation and enhanced thermal performance.

Both parts maintain identical operating temperature range (-40°C to 125°C) and ROHS3 compliance certification, satisfying regulatory and environmental requirements.

The substitute is classified as active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

The substitute is available in standard Tape & Reel packaging, supporting automated assembly processes and volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can SCRH5D28-220 be used as a direct replacement for SCB63C-220?

A: Yes. Both parts share identical inductance value (22 µH), physical dimensions (6.20 mm × 6.20 mm), and mounting type (surface mount). The substitute provides improved current rating and reduced DC resistance, making it functionally superior for the same application space.

Q: What are the key differences between these parts?

A: The primary differences are current rating (1.7 A versus 1.3 A), DC resistance (122 mOhm versus 191 mOhm), inductance tolerance (±30% versus ±20%), and product status (active versus obsolete). The substitute offers better thermal performance and supply availability.

Q: Does the inductance tolerance difference affect substitution?

A: The SCRH5D28-220 has ±30% tolerance compared to ±20% for the original part. Circuit designs must accommodate this wider tolerance band. If the original ±20% tolerance is a critical requirement, this difference must be evaluated against specific application constraints.

Q: Are there any packaging considerations?

A: The SCB63C-220 is supplied in bulk packaging, while the SCRH5D28-220 is supplied in Tape & Reel format. This difference supports automated assembly processes but does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8504.50.8000.
