Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24S680C is determined by the following critical parameters:

• Inductance Value: Must be 68 µH to maintain circuit performance
• Shielding Type: Must be shielded to prevent electromagnetic interference
• Current Rating: Substitute must support minimum 630 mA; higher ratings provide design margin
• DC Resistance: Lower DCR values reduce power dissipation and heat generation
• Operating Temperature Range: Must encompass or exceed -40°C ~ 85°C
• Mounting Type: Must be Surface Mount compatible
• Compliance: RoHS3 compliance required for regulatory alignment

The SRR7045-680M from Bourns Inc. meets these substitution criteria with matching inductance, shielding, and compliance certifications while providing enhanced current handling and lower DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The SRR7045-680M qualifies as a direct substitute for the 24S680C based on matching inductance specification, identical shielding configuration, and equivalent compliance certifications. Both components maintain RoHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

The SRR7045-680M provides design advantages through higher current rating capacity (1.2 A versus 630 mA) and reduced DC resistance (210mOhm versus 370mOhm), resulting in lower thermal dissipation. The extended operating temperature range (-40°C ~ 125°C) accommodates broader application environments compared to the 24S680C specification.

Selection between these components should be based on current budget requirements, thermal management constraints, and available inventory. Both components are Active status products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can the SRR7045-680M replace the 24S680C in existing designs?

A: Yes. Both components share identical 68 µH inductance values, shielded configuration, and surface mount packaging. The SRR7045-680M provides higher current capacity and lower DC resistance, making it suitable for direct substitution without circuit redesign.

Q: What are the key differences between these inductors?

A: The primary differences are current rating (SRR7045-680M: 1.2 A versus 24S680C: 630 mA), DC resistance (SRR7045-680M: 210mOhm versus 24S680C: 370mOhm), and operating temperature range (SRR7045-680M: -40°C ~ 125°C versus 24S680C: -40°C ~ 85°C). Inductance and shielding characteristics are identical.

Q: Are both components RoHS compliant?

A: Yes. Both the 24S680C and SRR7045-680M are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting current regulatory requirements.

Q: What is the physical size difference?

A: The 24S680C measures 0.303" L x 0.280" W x 0.177" H (7.70mm x 7.10mm x 4.50mm). The SRR7045-680M measures 0.276" L x 0.276" W x 0.189" H (7.00mm x 7.00mm x 4.80mm). Both are nonstandard package sizes suitable for surface mount assembly.

Q: Which component should be selected for thermal-constrained applications?

A: The SRR7045-680M is preferred for applications with thermal constraints due to its lower DC resistance (210mOhm), which reduces power dissipation compared to the 24S680C (370mOhm).
