Engineering Selection Recommendations

Direct Substitutes (Preferred):

B82476A1224M000 and B82476B1224M100 (EPCOS - TDK Electronics) are the primary direct substitutes. Both feature ferrite drum core construction matching the UP2C-221-R, with superior DCR specifications (530 mOhm max versus 545 mOhm). B82476B1224M100 provides higher current rating (880 mA) with extended temperature range (-55°C to 150°C) and AEC-Q200 automotive qualification. Both are ROHS3 compliant with unlimited MSL rating. Dimensional compatibility is confirmed within tolerance.

Compatible Alternatives:

P0752.224NLT and P0752.224NL (Pulse Electronics) provide 220 µH inductance with 800 mA current rating and extended operating temperature to 130°C. DCR specification is 840 mOhm max, representing acceptable performance variation. These parts are wirewound construction without specified core material. Both are ROHS3 compliant with unlimited MSL. Dimensional compatibility is confirmed.

Limited Substitution:

SDR1005-221KL (Bourns Inc.) meets core electrical specifications with ferrite drum core construction and superior ±10% tolerance. However, the 700 mA current rating is below the UP2C-221-R 820 mA specification. This part is suitable only for applications where continuous current does not exceed 700 mA. DCR is 780 mOhm max. Operating temperature extends to 125°C. ROHS3 compliant with unlimited MSL. Dimensional variation in width (10.00 mm versus 9.40 mm) requires PCB layout verification.

Compliance Status:

All substitute parts maintain RoHS3 compliance and MSL 1 rating. EPCOS B82476B1224M100 includes AEC-Q200 automotive qualification for applications requiring automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can P0752.224NLT replace UP2C-221-R in all applications?

A: P0752.224NLT is electrically compatible for applications where continuous current does not exceed 800 mA and operating temperature remains within -40°C to 130°C. The 840 mOhm max DCR is higher than the UP2C-221-R 545 mOhm specification, resulting in increased power dissipation. Thermal analysis is required for high-current applications.

Q: What is the difference between B82476A1224M000 and B82476B1224M100?

A: Both are EPCOS ferrite drum core inductors with identical 220 µH inductance and 530 mOhm max DCR. B82476B1224M100 provides higher current rating (880 mA versus 800 mA) and includes AEC-Q200 automotive qualification. Both support -55°C to 150°C operating temperature. Selection depends on application current requirements and automotive compliance needs.

Q: Is SDR1005-221KL suitable as a direct replacement?

A: SDR1005-221KL meets inductance and core type specifications but has 700 mA current rating, which is 120 mA below the UP2C-221-R 820 mA rating. This part is suitable only for applications with maximum continuous current of 700 mA. Width dimension is 10.00 mm versus 9.40 mm, requiring PCB layout verification.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts and the UP2C-221-R carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging formats are available for these substitutes?

A: P0752.224NLT, SDR1005-221KL, B82476A1224M000, B82476B1224M100, and P0752.224NL are supplied in Tape & Reel (TR) format. The original UP2C-221-R packaging is listed as nonstandard. Verify packaging compatibility with assembly equipment requirements.

Q: Are there temperature range considerations for substitute selection?

A: The UP2C-221-R operates -40°C to 85°C. All substitute parts extend the upper temperature limit to 125°C or higher. For applications operating above 85°C, EPCOS parts (150°C max) or Pulse/Bourns parts (125°C to 130°C max) are required. For applications below -40°C, EPCOS parts support -55°C minimum.

Q: How does DCR variation affect circuit performance?

A: DCR directly impacts power dissipation and voltage drop across the inductor. The UP2C-221-R 545 mOhm baseline should be compared against substitute DCR values. EPCOS parts (530 mOhm) provide lower dissipation. Pulse parts (840 mOhm) result in higher dissipation. Calculate power loss as P = I²R using maximum continuous current to determine thermal impact.
