Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 47101SC is determined by the following critical parameters:

• Inductance Value: Must be 100 µH
• Current Rating: Must support minimum 1.3 A
• DC Resistance: Must not exceed 267 mOhm to maintain equivalent power loss characteristics
• Shielding: Must be shielded to preserve EMI performance
• Mounting Type: Must be surface mount compatible
• Operating Temperature Range: Must encompass or exceed -40°C to 85°C
• Package Compatibility: Must accommodate nonstandard 4-lead surface mount footprint

The three substitute parts listed below meet these core electrical and mechanical requirements while offering active product status and enhanced temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

7447715101 (Würth Elektronik WE-PD Series)

This substitute offers the closest electrical match to the 47101SC. The DCR specification of 270 mOhm is within 1.1% of the original part, ensuring equivalent power dissipation characteristics. The part carries AEC-Q200 automotive qualification and extends the operating temperature range to 125°C. Footprint dimensions are slightly smaller (12.00mm vs 12.20mm), which may require PCB layout verification. This part is actively manufactured and widely available.

BPSC00131345101M00 (Pulse Electronics BPSC Series)

This substitute maintains the 100 µH inductance and ±20% tolerance specification. The DCR of 308 mOhm represents a 15.4% increase over the original part, which may impact thermal performance in current-limited applications. The saturation current of 1.2 A is below the 1.3 A rating of the original part. Extended temperature range to 125°C and ROHS3 compliance are provided. Footprint is slightly larger (12.50mm vs 12.20mm).

BPSC00131345101T00 (Pulse Electronics BPSC Series)

This variant shares electrical specifications with BPSC00131345101M00 but specifies a wider inductance tolerance of ±30%, which may not be acceptable for precision applications. The same DCR and saturation current limitations apply. This part is suitable only where inductance tolerance relaxation is permissible.

Frequently Asked Questions (FAQ)

Q: Can the 7447715101 be used as a direct replacement for the 47101SC?

A: The 7447715101 meets all critical electrical parameters: 100 µH inductance, 1.3 A current rating, and DCR within specification. Footprint dimensions are slightly smaller, requiring PCB layout verification. The part is actively manufactured and recommended for new designs.

Q: What is the impact of higher DCR in the Pulse Electronics substitutes?

A: The BPSC series parts specify 308 mOhm DCR compared to 267 mOhm for the 47101SC. This 15.4% increase results in proportionally higher resistive losses. In applications where thermal performance is critical, this may require thermal analysis or design adjustment.

Q: Are the Pulse Electronics parts suitable for applications requiring 1.3 A continuous current?

A: The BPSC series specifies saturation current (Isat) of 1.2 A, which is below the 1.3 A rating of the original part. These parts are suitable only for applications where the actual operating current remains below 1.2 A.

Q: What are the footprint considerations for substitution?

A: The 47101SC measures 12.20mm x 12.20mm with 5.00mm height. The Würth 7447715101 is slightly smaller at 12.00mm x 12.00mm with 4.50mm height. The Pulse Electronics parts are slightly larger at 12.50mm x 12.50mm with 4.50mm height. PCB layout verification is required for any substitution.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The 47101SC is RoHS Compliant, and all three substitute parts are ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the difference between BPSC00131345101M00 and BPSC00131345101T00?

A: Both parts share identical electrical and thermal specifications. The primary difference is inductance tolerance: BPSC00131345101M00 specifies ±20%, while BPSC00131345101T00 specifies ±30%. Selection depends on tolerance requirements for the application.
