Substitute Part Grouping Explanation

Substitution eligibility for the SCRH105-8R2 is determined by the following critical parameters:

  • Inductance Value: Must match 8.2 µH with ±30% tolerance specification
  • Current Rating: Substitute must support minimum 2.9 A continuous current
  • DC Resistance: Must not exceed 56 mOhm to maintain circuit performance
  • Operating Temperature: Must cover -40°C to 125°C range
  • Mounting Type: Surface mount configuration required
  • Compliance: RoHS3 compliance mandatory for regulatory alignment

The SRN6045-8R2Y meets these substitution criteria with equivalent inductance, comparable current handling, and matching temperature specifications. Both parts share identical inductance values, tolerance ratings, and compliance certifications.

Engineering Selection Recommendations

Both the SCRH105-8R2 and SRN6045-8R2Y maintain Active product status with full RoHS3 compliance and REACH unaffected certifications. The SRN6045-8R2Y is available in higher inventory quantities (5280 pcs vs 683 pcs), supporting supply chain continuity. Both components carry MSL 1 (Unlimited) moisture sensitivity ratings, eliminating storage and handling restrictions. Selection between these parts should account for the saturation current differential (5.4 A vs 3.3 A) and shielding configuration (Shielded vs Semi-Shielded) based on specific circuit requirements and electromagnetic interference considerations.

Frequently Asked Questions (FAQ)

Q: Can the SRN6045-8R2Y directly replace the SCRH105-8R2 in all applications?

A: Direct replacement is possible when circuit design accommodates the lower saturation current (3.3 A vs 5.4 A) and semi-shielded configuration of the SRN6045-8R2Y. The 2.7 A continuous current rating of the substitute is acceptable for applications designed for 2.9 A operation with appropriate thermal margin analysis.

Q: What is the significance of the shielding difference between these parts?

A: The SCRH105-8R2 provides full shielding, while the SRN6045-8R2Y offers semi-shielded construction. Shielding reduces electromagnetic radiation and susceptibility to external fields. Applications requiring maximum EMI suppression should prioritize the fully shielded SCRH105-8R2.

Q: Are the DC resistance values compatible?

A: Yes. The SRN6045-8R2Y DC resistance of 55 mOhm Max is lower than the SCRH105-8R2 specification of 56 mOhm Max, resulting in reduced power dissipation and improved efficiency in the substitute part.

Q: Do both parts support the same temperature operating range?

A: Yes. Both components operate across -40°C to 125°C, ensuring thermal compatibility in industrial and commercial applications.

Q: What packaging considerations apply to these parts?

A: Both parts are surface mount components in nonstandard packages supplied on Tape & Reel (TR). Physical dimensions differ: SCRH105-8R2 measures 10.10mm x 9.20mm x 6.00mm (max height), while SRN6045-8R2Y measures 6.00mm x 6.00mm x 4.50mm (max height). PCB layout and thermal management designs must account for these dimensional variations.
