Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24S6R8C is determined by the following critical parameters:

Inductance Value: Must be 6.8 µH to maintain circuit performance and impedance matching.

Shielding Requirement: Must be shielded to prevent electromagnetic interference in the target application.

Mounting Configuration: Must support surface mount technology for PCB integration compatibility.

Current Handling Capability: The substitute must support the application's current requirements. The 24S6R8C is rated for 2 A; substitutes with equal or higher current ratings are acceptable.

DC Resistance: Lower or equal DCR values are preferred to minimize power dissipation. The 24S6R8C specifies 45mOhm maximum; substitutes with 45mOhm or lower DCR maintain or improve thermal performance.

Environmental Compliance: Must maintain ROHS3 compliance and REACH unaffected status for regulatory alignment.

The SRR7045-6R8M from Bourns Inc. meets all substitution criteria with matching inductance, shielding, and surface mount configuration, while offering improved current rating (3.1 A vs. 2 A) and lower DCR (36mOhm vs. 45mOhm).

Parameter Comparison

Engineering Selection Recommendations

Both the 24S6R8C and SRR7045-6R8M are active production components with full regulatory compliance (ROHS3 and REACH unaffected status). Selection between these parts should be based on application-specific requirements:

The 24S6R8C remains the primary choice when the original design specifications and thermal characteristics are critical to system performance.

The SRR7045-6R8M serves as a qualified substitute when supply availability of the primary part is constrained. This substitute provides electrical performance improvements through lower DC resistance (36mOhm vs. 45mOhm) and higher current rating capability (3.1 A vs. 2 A), resulting in reduced power dissipation and improved thermal margin. The extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C) provides additional environmental flexibility.

Physical dimensions differ slightly between the two parts. The 24S6R8C measures 0.303" L x 0.280" W x 0.177" H (7.70mm x 7.10mm x 4.50mm), while the SRR7045-6R8M measures 0.276" L x 0.276" W x 0.189" H (7.00mm x 7.00mm x 4.80mm). PCB layout verification is necessary to confirm mechanical fit within the available footprint space.

Frequently Asked Questions (FAQ)

Q: Can the SRR7045-6R8M directly replace the 24S6R8C without circuit modification?

A: The SRR7045-6R8M is electrically compatible as a substitute, matching the critical inductance value of 6.8 µH and shielding configuration. However, physical dimensions differ slightly. PCB layout must be verified to confirm the substitute component fits within the allocated space. No circuit modifications are required if mechanical fit is confirmed.

Q: What is the significance of the lower DC resistance in the SRR7045-6R8M?

A: The SRR7045-6R8M specifies 36mOhm maximum DCR compared to 45mOhm maximum for the 24S6R8C. Lower DC resistance reduces resistive power dissipation (P = I²R), resulting in lower operating temperature and improved thermal performance under the same current conditions.

Q: Are both parts suitable for high-temperature applications?

A: The 24S6R8C operates within -40°C to 85°C. The SRR7045-6R8M extends this range to -40°C to 125°C. For applications requiring operation above 85°C, the SRR7045-6R8M provides the necessary thermal rating. For applications within the 24S6R8C's specified range, both parts are suitable.

Q: What does the difference in self-resonant frequency mean for circuit design?

A: The 24S6R8C has a self-resonant frequency of 39 MHz, while the SRR7045-6R8M is 28 MHz. Self-resonant frequency defines the upper frequency limit where the inductor behaves as intended. Applications operating near or above these frequencies require careful evaluation to ensure the selected part maintains proper inductive behavior.

Q: Are both parts available in the same packaging format?

A: Both the 24S6R8C and SRR7045-6R8M are supplied in Tape & Reel (TR) packaging for automated assembly. Both use nonstandard package cases. Verify that your assembly equipment and processes are compatible with the specific physical dimensions of the selected part.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the 24S6R8C and SRR7045-6R8M are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8504.50.4000.
