Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCR63B-680 is determined by the following critical parameters:

• Inductance Value: Must be 68 µH with ±20% tolerance
• Shielding: Must be shielded to maintain electromagnetic compatibility
• Current Rating: Substitute must support minimum 570 mA continuous current
• DC Resistance: Lower DCR values are acceptable; higher values may impact circuit performance
• Operating Temperature: Must support -40°C to 125°C range
• Mounting Type: Surface mount configuration required
• Compliance: ROHS3 compliance mandatory

The ASPI-6045S-680M-T from Abracon LLC meets these substitution criteria with improved electrical characteristics, including higher current rating (1 A), lower DC resistance (289 mOhm), and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-6045S-680M-T is the qualified substitute for the obsolete SCR63B-680. Both components maintain identical inductance values and tolerance specifications, with matching operating temperature ranges and compliance certifications. The substitute part offers superior electrical performance through increased current rating (1 A versus 570 mA) and significantly reduced DC resistance (289 mOhm versus 820 mOhm maximum). Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Physical dimensions differ slightly: the substitute is marginally smaller in length and width (6.00mm x 6.00mm versus 6.50mm x 5.90mm) but taller (4.50mm versus 4.60mm seated height). PCB layout verification is required to confirm clearance compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-6045S-680M-T directly replace the SCR63B-680 in existing designs?

A: The substitute meets all critical electrical parameters: identical 68 µH inductance, matching ±20% tolerance, equivalent shielding, and identical operating temperature range. Physical dimensions require PCB layout verification due to increased seated height (4.50mm versus 4.60mm).

Q: What are the key advantages of the ASPI-6045S-680M-T substitute?

A: The substitute provides higher current rating (1 A versus 570 mA), lower DC resistance (289 mOhm versus 820 mOhm), and active product status ensuring long-term availability and supply chain continuity.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the SCR63B-680 and ASPI-6045S-680M-T are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.50.8000).

Q: What is the primary reason for substitution?

A: The SCR63B-680 is classified as obsolete. The ASPI-6045S-680M-T is an active product from a major manufacturer, providing design continuity and procurement reliability.

Q: Are there packaging differences between these parts?

A: The main part is supplied as nonstandard packaging. The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.
