Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Electrical Parameters:

• Inductance value: 10 µH (exact match required)
• Current rating: minimum 4.3 A
• DC resistance: maximum 31 mOhm
• Saturation current: minimum 10 A
• Shielding configuration: Unshielded

Mechanical & Environmental Parameters:

• Mounting type: Surface Mount (nonstandard package)
• Operating temperature range: minimum -40°C ~ 125°C
• RoHS3 compliance: required
• Moisture sensitivity level: 1 (Unlimited)

All three substitute parts meet these criteria. The Würth Elektronik 74458010 and Bourns SDR1806-100ML and SDR2207-100ML maintain the core electrical specifications while offering variations in current capacity and DC resistance that support direct substitution in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are classified as Active product status with full RoHS3 compliance and REACH unaffected designation, matching the regulatory and compliance profile of the P0250.103NL.

Würth Elektronik 74458010: Maintains identical current rating (4.3 A) and DC resistance specification (31 mOhm Max) as the main part. Operating temperature range is -40°C ~ 125°C, which is 5°C lower than the main part's maximum. Suitable for applications where the main part specifications are critical.

Bourns SDR1806-100ML: Provides increased current capacity (5.3 A) with improved DC resistance (25 mOhm Max). Operating temperature range is -40°C ~ 125°C. Inductance tolerance is ±20% compared to the main part's ±15%. Suitable for applications requiring lower DC resistance or higher current margin.

Bourns SDR2207-100ML: Provides the highest current capacity (6.5 A) with the lowest DC resistance (17.2 mOhm Max). Operating temperature range is -40°C ~ 125°C. Inductance tolerance is ±20%. Suitable for applications requiring maximum current headroom or minimal resistive losses.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 74458010 be used as a direct replacement for the P0250.103NL?

A: Yes. The 74458010 maintains identical current rating (4.3 A) and DC resistance (31 mOhm Max) specifications. The operating temperature maximum is 5°C lower (-40°C ~ 125°C vs. -40°C ~ 130°C). Both parts are RoHS3 compliant with unlimited moisture sensitivity rating and 100 kHz test frequency.

Q: What is the difference between the Bourns SDR1806-100ML and SDR2207-100ML?

A: Both are 10 µH inductors with identical inductance and saturation current. The SDR2207-100ML provides higher current capacity (6.5 A vs. 5.3 A) and lower DC resistance (17.2 mOhm vs. 25 mOhm). The SDR2207-100ML is physically larger (22.00mm L x 15.00mm W x 7.80mm H vs. 18.30mm L x 14.00mm W x 6.90mm H).

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All substitute parts are surface mount with nonstandard packages. Physical dimensions vary slightly. The P0250.103NL measures 18.62mm L x 15.14mm W x 7.36mm H. The 74458010 measures 18.54mm L x 15.24mm W x 7.11mm H. The SDR1806-100ML measures 18.30mm L x 14.00mm W x 6.90mm H. The SDR2207-100ML measures 22.00mm L x 15.00mm W x 7.80mm H. Verify PCB layout and clearance requirements before substitution.

Q: What is the significance of the inductance tolerance difference?

A: The P0250.103NL has ±15% tolerance, while all substitute parts have ±20% tolerance. In applications where inductance accuracy is critical, the tighter tolerance of the main part may be required. For general applications, the ±20% tolerance of substitute parts is acceptable for 10 µH inductors tested at 100 kHz.

Q: Do all parts meet the same regulatory requirements?

A: Yes. All parts are RoHS3 compliant, REACH unaffected, and classified under HTSUS 8504.50.4000 with ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts.
