Engineering Selection Recommendations
Direct Equivalents (Preferred Substitutes):
B82476A1223M000 (EPCOS - TDK Electronics) is the primary direct equivalent. This part maintains the 22 µH inductance, ±20% tolerance, ferrite drum core construction, and unshielded configuration. The current rating of 2.7 A exceeds the original 2.61 A requirement. DC resistance of 50 mOhm maximum is lower than the original 54 mOhm, providing improved efficiency. Operating temperature range extends to -55°C to 150°C, encompassing the original -40°C to 85°C specification. ROHS3 compliance and active product status ensure long-term availability. Tape & Reel packaging is standard for production environments.
B82476B1223M100 (EPCOS - TDK Electronics) provides enhanced current capability at 2.95 A with identical DC resistance of 50 mOhm maximum and ferrite drum core construction. This part includes AEC-Q200 automotive qualification, extending application scope. Operating temperature range of -55°C to 150°C and ROHS3 compliance match B82476A1223M000. Physical dimensions are nearly identical to the original part.
Compatible Substitutes (Application-Dependent):
P0751.223NLT (Pulse Electronics) matches the 22 µH inductance and ±20% tolerance with 2.6 A current rating. DC resistance of 114 mOhm maximum is significantly higher than the original 54 mOhm specification. This part is suitable for applications where power dissipation from increased resistance is acceptable. Operating temperature range of -40°C to 130°C encompasses the original specification. ROHS3 compliance and active status are confirmed.
P0751.223NL (Pulse Electronics) is functionally identical to P0751.223NLT with equivalent electrical and thermal specifications. Packaging format differs (bulk versus Tape & Reel), with no impact on electrical performance.
SDR1005-220ML (Bourns Inc.) maintains 22 µH inductance and ±20% tolerance with ferrite drum core construction. Current rating of 2.0 A is below the original 2.61 A specification, limiting this part to lower-current applications. DC resistance of 100 mOhm maximum is higher than the original. Operating temperature range of -40°C to 125°C encompasses the original specification. ROHS3 compliance and active status are confirmed. Inductance test frequency of 1 kHz differs from the original 100 kHz specification.
Selection Criteria Summary:
For direct replacement in existing designs with no current derating, B82476A1223M000 or B82476B1223M100 are recommended. Both parts are active, ROHS3 compliant, and provide equivalent or superior electrical performance. B82476B1223M100 is preferred for automotive or high-reliability applications due to AEC-Q200 qualification.
For applications tolerating increased DC resistance and lower current ratings, P0751.223NLT or SDR1005-220ML are acceptable alternatives. These parts remain active and ROHS3 compliant but require thermal and current-handling verification.
Frequently Asked Questions (FAQ)
Q: Can B82476A1223M000 be used as a direct replacement for UP2C-220-R?
A: Yes. Both parts share identical inductance (22 µH), tolerance (±20%), core type (ferrite drum core), shielding (unshielded), and mounting configuration (surface mount). The B82476A1223M000 provides equal or superior electrical performance with higher current rating (2.7 A versus 2.61 A) and lower DC resistance (50 mOhm maximum versus 54 mOhm). Operating temperature range extends beyond the original specification.
Q: What is the impact of higher DC resistance in P0751.223NLT compared to the original part?
A: The P0751.223NLT exhibits 114 mOhm maximum DC resistance versus 54 mOhm in the UP2C-220-R. This doubles the resistive losses, resulting in increased power dissipation and heat generation at rated current. Applications must accommodate this additional thermal load. Substitution is valid only when thermal margins permit the increased dissipation.
Q: Are all substitute parts ROHS3 compliant?
A: All active substitute parts listed (B82476A1223M000, P0751.223NLT, B82476B1223M100, P0751.223NL, and SDR1005-220ML) are ROHS3 compliant. The original UP2C-220-R compliance status is not specified in available documentation.
Q: Does the difference in inductance test frequency between SDR1005-220ML (1 kHz) and the original part (100 kHz) affect substitution?
A: Inductance values are frequency-dependent in ferrite-core inductors. Testing at different frequencies may yield slightly different measured inductance values. For applications requiring inductance measurement at 100 kHz, SDR1005-220ML should be characterized at the application frequency to confirm performance. The ±20% tolerance specification applies to the test frequency used by each manufacturer.
Q: Can B82476B1223M100 be used in non-automotive applications?
A: Yes. AEC-Q200 qualification indicates automotive-grade reliability and is not restrictive for non-automotive use. B82476B1223M100 is suitable for any application requiring 22 µH inductance with 2.95 A current capability and ferrite drum core construction.
Q: What are the physical dimension constraints for PCB layout?
A: The original UP2C-220-R measures 12.90 mm L × 9.40 mm W × 5.20 mm H. Substitute parts vary slightly: B82476A1223M000 and B82476B1223M100 measure 12.95 mm × 9.40 mm × 5.08 mm; P0751.223NLT and P0751.223NL measure 12.95 mm × 9.40 mm × 5.46 mm; SDR1005-220ML measures 12.70 mm × 10.00 mm × 5.00 mm. PCB footprints must accommodate these dimensional variations, particularly the width difference in SDR1005-220ML (10.00 mm versus 9.40 mm).
Q: Which substitute part offers the best long-term availability?
A: All listed substitute parts carry active product status from established manufacturers (EPCOS - TDK Electronics, Pulse Electronics, and Bourns Inc.). Active status indicates ongoing production and distribution support. B82476A1223M000 and B82476B1223M100 from EPCOS - TDK are part of established industrial inductor series with broad market adoption, supporting extended availability.
Q: Is Tape & Reel packaging required for production use?
A: Tape & Reel packaging is standard for automated assembly processes. B82476A1223M000, B82476B1223M100, P0751.223NLT, and SDR1005-220ML are available in Tape & Reel format. P0751.223NL packaging format is not specified but does not affect electrical performance. Packaging selection depends on assembly process requirements, not component functionality.
