Key Parameters

Substitute Part Grouping Explanation

The ASPI-0628-220M-T1 from Abracon LLC qualifies as a direct substitute for the SCR63B-220 based on the following critical parameters:

Matching Parameters:

• Inductance: 22 µH (identical)
• Inductance Tolerance: ±20% (identical)
• Shielding: Shielded (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Superior Performance Characteristics:

• Current Rating: 1.4 A (exceeds 1.1 A requirement)
• Current - Saturation (Isat): 1.3 A (exceeds 760 mA requirement)
• DC Resistance (DCR): 135 mOhm (lower than 320 mOhm maximum)

The ASPI-0628-220M-T1 maintains electrical equivalence while providing improved current handling and reduced resistive losses. The substitute part is actively manufactured and available in standard tape and reel packaging.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0628-220M-T1 is the qualified substitute for the obsolete SCR63B-220. Both components meet ROHS3 compliance and carry identical moisture sensitivity ratings. The substitute part is currently in active production with confirmed inventory availability.

The ASPI-0628-220M-T1 provides enhanced electrical performance through lower DC resistance and higher saturation current, reducing thermal dissipation in the application circuit. The substitute maintains the required 22 µH inductance value and ±20% tolerance specification.

Physical dimensions differ slightly: the substitute is marginally smaller in length and width (6.00mm x 6.00mm versus 6.50mm x 5.90mm) and lower in height (2.80mm versus 4.60mm). These dimensional changes are compatible with standard surface mount assembly processes and PCB layouts designed for nonstandard inductor packages.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0628-220M-T1 directly replace the SCR63B-220 in existing designs?

A: Yes. Both components share identical inductance (22 µH), tolerance (±20%), shielding type, and mounting method. The substitute meets all compliance requirements of the original part.

Q: What are the key differences between these parts?

A: The primary differences are product status (active versus obsolete), DC resistance (135 mOhm versus 320 mOhm), current rating (1.4 A versus 1.1 A), and physical dimensions. The substitute offers improved electrical performance with lower resistive losses and higher current capacity.

Q: Are there packaging considerations for the substitute part?

A: The ASPI-0628-220M-T1 is supplied in tape and reel (TR) packaging, which is standard for automated assembly. The original SCR63B-220 packaging format is not specified in the available data. Verify that your assembly equipment is compatible with standard tape and reel formats.

Q: What is the operating temperature difference between these parts?

A: The SCR63B-220 operates from -40°C to 125°C, while the ASPI-0628-220M-T1 operates from -25°C to 120°C. If your application requires operation below -25°C or above 120°C, verify that the substitute meets your specific thermal requirements.

Q: How do the physical dimensions affect PCB layout?

A: The substitute part is slightly smaller in footprint (6.00mm x 6.00mm versus 6.50mm x 5.90mm) and lower in profile (2.80mm versus 4.60mm). These dimensional reductions are generally compatible with existing PCB designs, but verify clearance for any components or structures in close proximity to the inductor location.
