Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P0250.102NLT is determined by the following critical parameters:

• Inductance Value: Must be 1 µH (±20% tolerance acceptable for substitute parts)
• Current Rating: Substitute must support minimum 8.6 A continuous current
• DC Resistance: Lower DCR values are acceptable; higher values require application verification
• Saturation Current: Must meet or exceed 20 A minimum threshold
• Mounting Type: Surface mount configuration required
• Shielding Configuration: Unshielded topology maintained
• Compliance: ROHS3 and REACH compliance required

The SDR1806-1R0ML meets these substitution criteria with equivalent inductance, superior current handling (10 A vs 8.6 A), and improved DC resistance characteristics (4mOhm vs 9mOhm).

Parameter Comparison

Engineering Selection Recommendations

Both the P0250.102NLT and SDR1806-1R0ML are Active status components with full ROHS3 and REACH compliance. The SDR1806-1R0ML provides performance advantages including higher current rating (10 A vs 8.6 A), superior saturation current (30 A vs 20 A), and significantly lower DC resistance (4mOhm vs 9mOhm). The substitute part operates within the required temperature range with a 5°C lower maximum specification. Both components maintain unshielded wirewound construction and surface mount packaging. Selection between these parts should be based on current application requirements, thermal dissipation considerations related to DCR differences, and physical space constraints given the minor dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can the SDR1806-1R0ML directly replace the P0250.102NLT in all applications?

A: Direct substitution is valid when the application current requirement does not exceed 8.6 A continuous operation. The SDR1806-1R0ML's superior current rating and lower DC resistance provide additional design margin. Verify that the 5°C lower maximum operating temperature (125°C vs 130°C) is acceptable for your thermal environment.

Q: What is the significance of the different tolerance specifications (±15% vs ±20%)?

A: The P0250.102NLT maintains tighter inductance tolerance at ±15%, while the SDR1806-1R0ML allows ±20%. For applications requiring strict inductance accuracy, the main part specification is preferred. For general-purpose filtering and energy storage applications, the ±20% tolerance is typically acceptable.

Q: How does the lower DC resistance of the SDR1806-1R0ML affect circuit performance?

A: Lower DC resistance (4mOhm vs 9mOhm) reduces resistive losses and heat generation during operation. This is advantageous in high-current applications and reduces thermal stress on the component and surrounding circuitry.

Q: Are there physical mounting differences between these parts?

A: Both components use surface mount technology with nonstandard package dimensions. The SDR1806-1R0ML is slightly smaller (18.30mm x 14.00mm x 6.90mm vs 18.62mm x 15.14mm x 7.36mm). Verify PCB footprint compatibility before substitution.

Q: What packaging formats are available for these inductors?

A: The P0250.102NLT is available in standard packaging. The SDR1806-1R0ML is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.
