Frequently Asked Questions (FAQ)

Q: Can P0752.104NLT be used as a direct replacement for UP2C-101-R?

A: P0752.104NLT qualifies as a direct substitute. Both parts maintain 100 µH inductance at ±20% tolerance, unshielded configuration, and surface mount design. Current rating of 1.2 A is marginally below the main part specification of 1.26 A. DC resistance of 380 mOhm Max is higher than the main part value of 233.1 mOhm. Extended operating temperature range to 130°C provides additional thermal margin. Substitution is appropriate when application current requirements do not exceed 1.2 A and higher DC resistance is acceptable.

Q: What is the difference between B82476A1104M000 and B82476B1104M100?

A: Both parts are EPCOS - TDK Electronics products with 100 µH inductance at ±20% tolerance and identical DC resistance of 230 mOhm Max. The primary difference is current rating: B82476A1104M000 is rated for 1.3 A, while B82476B1104M100 is rated for 1.4 A. B82476B1104M100 includes AEC-Q200 automotive qualification rating, making it suitable for automotive applications. Both parts maintain identical operating temperature range of -55°C to 150°C and ROHS3 compliance.

Q: Why does SDR1005-101KL have a different inductance test frequency?

A: SDR1005-101KL specifies inductance test frequency of 1 kHz, while the main part UP2C-101-R and most substitute parts specify 100 kHz. Inductance values are frequency-dependent due to core material characteristics. The 100 µH specification is valid at the stated test frequency. When selecting SDR1005-101KL as a substitute, confirm that the inductance value measured at 1 kHz meets application requirements, as inductance may vary at different measurement frequencies.

Q: Can I use B82476B1104M100 in place of UP2C-101-R in a high-temperature application?

A: B82476B1104M100 is suitable for high-temperature applications. This part maintains operating temperature range of -55°C to 150°C, compared to the main part range of -40°C to 85°C. Current rating of 1.4 A exceeds the main part specification of 1.26 A. DC resistance of 230 mOhm Max is lower than the main part value of 233.1 mOhm. AEC-Q200 automotive qualification provides additional reliability assurance. Substitution is appropriate when extended temperature operation is required.

Q: What is the impact of higher DC resistance in substitute parts?

A: DC resistance directly affects power dissipation in the inductor. Higher DC resistance results in increased I²R losses during current flow. P0752.104NLT and P0752.104NL specify 380 mOhm Max compared to the main part value of 233.1 mOhm, representing approximately 63% higher resistance. SDR1005-101KL specifies 330 mOhm Max, representing approximately 42% higher resistance. B82476A1104M000 and B82476B1104M100 specify 230 mOhm Max, representing lower resistance than the main part. Substitution with higher DC resistance is appropriate when application thermal design accommodates increased power dissipation.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts maintain ROHS3 compliance status, meeting current regulatory requirements. The main part UP2C-101-R is listed as RoHS Compliant. All parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging formats are available for substitute parts?

A: P0752.104NLT is supplied in Tape & Reel (TR) format with 3163 units in inventory. P0752.104NL packaging format is not specified in available data with 2000 units in inventory. SDR1005-101KL, B82476A1104M000, and B82476B1104M100 are all supplied in Tape & Reel (TR) format. Confirm packaging requirements with procurement specifications before component selection.

Q: Can SDR1005-101KL be used in applications requiring 1.26 A continuous current?

A: SDR1005-101KL is rated for 1 A continuous current, which is below the main part specification of 1.26 A. This part is not suitable for applications requiring continuous current operation at 1.26 A. Saturation current is specified at 1.2 A. Substitution with SDR1005-101KL is appropriate only when application current requirements do not exceed 1 A continuous operation.
