Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Inductance Value: Must be 10 µH (exact match required)
Shielding: Must be shielded (electromagnetic containment requirement)
Mounting Type: Must be surface mount (PCB assembly compatibility)
Package Footprint: Must accommodate 0.079" L x 0.063" W (2.00mm x 1.60mm) dimensions
Current Rating: Must meet or exceed 400 mA application requirement
DC Resistance: Lower DCR values improve efficiency; higher values acceptable if current rating is sufficient
Operating Temperature Range: Must cover -40°C ~ 105°C minimum
Compliance: Must maintain ROHS3 compliance

All identified substitute parts meet these core substitution criteria. Variations in tolerance, saturation current, and height are secondary parameters that do not prevent functional substitution when primary parameters align.

Engineering Selection Recommendations

Primary Recommendation: VLS201610CX-100M-1

This TDK Corporation part maintains manufacturer continuity while offering active product status. It provides superior electrical performance with 710 mA current rating and reduced DCR of 0.732 Ohm, delivering lower power dissipation than the original VLS201610ET-100M. Operating temperature range remains -40°C ~ 105°C, and ROHS3 compliance is maintained.

Secondary Recommendations: Pulse Electronics BWVC Series

The BWVC00201610100M00 and BWVC00201610100T00 parts provide cross-manufacturer alternatives with 500 mA current rating, exceeding the 400 mA requirement. These parts offer extended operating temperature range (-55°C ~ 125°C) and active product status. The BWVC00201610100M00 maintains ±20% tolerance matching the original specification.

Alternative: Pulse Electronics BWVH Series

The BWVH00201610100MH1 and BWVH00201610100TH1 parts are suitable for applications where the 380 mA current rating is sufficient. These parts feature active product status, extended temperature range, and ROHS3 compliance. The BWVH00201610100MH1 maintains ±20% tolerance.

All substitute parts maintain ROHS3 compliance and are available in active product status, ensuring long-term supply chain viability.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-100M-1 directly replace VLS201610ET-100M?

A: Yes. Both parts share identical inductance (10 µH), shielding, mounting type, and package footprint. The VLS201610CX-100M-1 offers higher current rating (710 mA vs. 400 mA) and lower DCR (0.732 Ohm vs. 1.38 Ohm), making it a direct functional upgrade.

Q: What is the difference between BWVC and BWVH series inductors?

A: Both series are manufactured by Pulse Electronics and meet the 10 µH, shielded, surface mount requirements. The BWVC series supports 500 mA current rating with 1.0 Ohm DCR. The BWVH series supports 380 mA current rating with 1.1 Ohm DCR. Selection depends on application current requirements.

Q: Are tolerance differences between ±20% and ±30% significant for substitution?

A: Tolerance differences affect inductance accuracy but do not prevent substitution. Parts marked ±20% (VLS201610ET-100M, VLS201610CX-100M-1, BWVC00201610100M00, BWVH00201610100MH1) provide tighter inductance control. Parts marked ±30% (BWVC00201610100T00, BWVH00201610100TH1) are acceptable where inductance variation within this range is tolerable.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All parts maintain the 0.079" L x 0.063" W (2.00mm x 1.60mm) footprint. Height variations (0.037" to 0.040") are within typical PCB assembly tolerances and do not affect placement compatibility.

Q: Why is VLS201610ET-100M marked "Not For New Designs"?

A: This designation indicates TDK has superseded this part in favor of newer alternatives. The VLS201610CX-100M-1 is the recommended TDK replacement, offering improved performance and active product status for ongoing production.

Q: Are extended temperature ranges (-55°C ~ 125°C) compatible with -40°C ~ 105°C applications?

A: Yes. Extended temperature range parts (Pulse Electronics BWVC and BWVH series) are fully compatible with applications requiring -40°C ~ 105°C operation, as they exceed this specification.
