Engineering Selection Recommendations

Würth Elektronik 744760068C (Primary Part): Active product status with established supply chain. ROHS3 compliant and MSL 1 rated. Suitable for standard applications requiring 6.8 nH inductance at 600 mA.

Bourns Inc. CW201212-6N8J (Direct Substitute): Active product status. ROHS3 compliant with MSL 1 rating. Offers lower DC resistance (60mOhm versus 110mOhm maximum), resulting in reduced power dissipation. Slightly higher Q factor (60 versus 50 at 1GHz) and self resonant frequency (5.8 GHz versus 5.5 GHz). Dimensional footprint is slightly smaller (2.10mm x 1.50mm). Suitable for applications where lower losses are beneficial.

TE Connectivity 36502A6N8JTDG (Manufacturer Recommended Substitute): Active product status with AEC-Q200 automotive qualification. ROHS3 compliant and MSL 1 rated. Electrical parameters match the primary part identically, including 110mOhm maximum DCR and 50 Q at 1GHz. Dimensional specifications are equivalent to the primary part. Recommended for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can the Bourns CW201212-6N8J be used as a direct replacement for the Würth Elektronik 744760068C?

A: Yes. Both parts maintain 6.8 nH inductance at ±5% tolerance, 600 mA current rating, ceramic core construction, and unshielded configuration. The Bourns part features lower DC resistance (60mOhm versus 110mOhm maximum), which reduces power dissipation. Dimensional differences within the 0805 package specification are acceptable for standard PCB layouts.

Q: What is the difference between the TE Connectivity 36502A6N8JTDG and the primary Würth part?

A: The TE Connectivity part is electrically and mechanically equivalent to the Würth Elektronik 744760068C. The primary distinction is AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. All critical electrical parameters, including inductance, current rating, DCR, and operating temperature range, are identical.

Q: Are all three parts compatible with the same PCB footprint?

A: All three parts use the 0805 package designation (Surface Mount). Dimensional variations are minor and within standard PCB design tolerances. The Bourns part has a slightly smaller footprint (2.10mm x 1.50mm) compared to the Würth (2.29mm x 1.70mm) and TE Connectivity (2.29mm x 1.73mm) parts. Standard 0805 pads accommodate all three variants.

Q: Which substitute part should be selected for lowest power dissipation?

A: The Bourns CW201212-6N8J offers the lowest DC resistance at 60mOhm, compared to 110mOhm maximum for both the Würth and TE Connectivity parts. This results in reduced I²R losses in applications operating at or near the 600 mA current rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The Würth Elektronik 744760068C, Bourns CW201212-6N8J, and TE Connectivity 36502A6N8JTDG are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.
