Substitute Part Grouping Explanation

Substitution of the 26120C with the Bourns SDR1006-120ML is based on the following critical parameters:

• Inductance Value: Both parts are rated at 12 µH, meeting the primary functional requirement
• Current Rating: The substitute provides 2.45 A, which exceeds the 2.42 A requirement of the main part
• DC Resistance: The substitute DCR of 70mOhm is within acceptable tolerance relative to the 68mOhm specification
• Shielding Configuration: Both parts are unshielded, maintaining electromagnetic compatibility characteristics
• Surface Mount Compatibility: Both components use surface mount technology with nonstandard package formats
• Operating Temperature Range: The substitute operates from -40°C to 125°C, which encompasses the main part's -40°C to 85°C range
• Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected

Parameter Comparison

Engineering Selection Recommendations

Both the 26120C and SDR1006-120ML are active production components with full ROHS3 compliance and REACH unaffected status. The Bourns SDR1006-120ML provides equivalent electrical performance with a higher current saturation rating of 4.5 A and an extended operating temperature range to 125°C. Selection between these parts should be based on application-specific requirements regarding temperature operating envelope, inventory availability, and mechanical fit within the assembly. The SDR1006-120ML is currently available in higher inventory quantity (2722 units) compared to the 26120C (756 units).

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-120ML be used as a direct replacement for the 26120C?

A: The SDR1006-120ML meets the electrical specifications of the 26120C with equivalent inductance, current rating, and DC resistance within acceptable parameters. Both components are surface mount, unshielded inductors with identical moisture sensitivity levels and regulatory compliance status.

Q: What are the dimensional differences between these parts?

A: The 26120C measures 0.394" L x 0.354" W (10.00mm x 9.00mm), while the SDR1006-120ML measures 0.386" L x 0.386" W (9.80mm x 9.80mm). Both have a maximum seated height of 0.228" (5.80mm). Dimensional compatibility must be verified for the specific PCB layout and assembly constraints.

Q: How do the self-resonant frequencies compare?

A: The 26120C has a self-resonant frequency of 24 MHz, while the SDR1006-120ML is rated at 20 MHz. This difference should be evaluated for applications where high-frequency performance is critical.

Q: Are both parts suitable for the same temperature range?

A: The 26120C operates from -40°C to 85°C, while the SDR1006-120ML operates from -40°C to 125°C. The substitute part provides extended high-temperature capability, making it suitable for applications requiring operation above 85°C.

Q: What is the difference in DC resistance between these inductors?

A: The 26120C has a maximum DCR of 68mOhm, while the SDR1006-120ML has a maximum DCR of 70mOhm. This 2mOhm difference is negligible for most applications and falls within normal manufacturing tolerances for wirewound inductors.
