Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS201612ET-2R2M is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (exact match required)
• Inductance tolerance: ±20% or tighter
• Core material: Ferrite shielded construction
• Mounting type: Surface Mount
• Package footprint: 2.00mm x 1.60mm (0806/2016 metric equivalent)
• RoHS3 compliance and MSL 1 rating

Secondary Compatibility Factors:

• Current rating must meet or exceed 1.05 A minimum requirement
• DC resistance should not significantly exceed 195 mOhm to avoid thermal performance degradation
• Operating temperature range must encompass -40°C ~ 105°C or broader
• Saturation current (Isat) should support the application's peak current demands

The three substitute parts listed below satisfy these criteria with variations in current handling capability, DC resistance, and product status.

Engineering Selection Recommendations

VLS201610CX-2R2M-1 (TDK Corporation - Recommended Primary Substitute)

This part is the manufacturer-recommended substitute from TDK's active product line. It maintains identical inductance (2.2 µH), tolerance (±20%), core material (ferrite), and operating temperature range. The VLS201610CX-2R2M-1 offers improved performance with higher current rating (1.53 A vs. 1.05 A), lower DC resistance (163 mOhm vs. 195 mOhm), and reduced height (1.00mm vs. 1.20mm). Product status is Active, ensuring long-term availability and supply continuity. This part is optimal for new designs and direct replacements where TDK ecosystem preference exists.

BWVC002016122R2M00 and BWVC002016122R2T00 (Pulse Electronics - Alternative Substitutes)

Both Pulse Electronics parts provide cross-manufacturer alternatives with identical inductance and package footprint. They deliver lower DC resistance (159 mOhm), higher current rating (1.2 A), and extended operating temperature range (-55°C ~ 125°C). Both parts are Active status. The primary difference between these two is inductance tolerance: BWVC002016122R2M00 maintains ±20% tolerance matching the original specification, while BWVC002016122R2T00 has ±30% tolerance. For applications requiring tighter inductance control, BWVC002016122R2M00 is the preferred Pulse Electronics option. Both parts are ROHS3 compliant and MSL 1 rated, meeting all regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-2R2M-1 be used as a direct replacement for VLS201612ET-2R2M?

A: Yes. Both parts share identical inductance (2.2 µH), tolerance (±20%), ferrite core material, shielding, operating temperature range, and package footprint (2.00mm x 1.60mm). The VLS201610CX-2R2M-1 offers superior electrical performance with higher current rating and lower DC resistance. The reduced height (1.00mm vs. 1.20mm) must be verified for PCB assembly clearance in existing designs.

Q: What are the key differences between the Pulse Electronics substitutes?

A: BWVC002016122R2M00 and BWVC002016122R2T00 are electrically identical with the same inductance, current rating, DC resistance, and operating temperature range. The sole difference is inductance tolerance: BWVC002016122R2M00 specifies ±20% tolerance, while BWVC002016122R2T00 specifies ±30% tolerance. For circuits requiring tighter inductance control, BWVC002016122R2M00 is the appropriate selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. VLS201610CX-2R2M-1, BWVC002016122R2M00, and BWVC002016122R2T00 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original VLS201612ET-2R2M specification.

Q: Will the substitute parts fit in the same PCB footprint?

A: All substitute parts maintain the identical package footprint of 0.079" L x 0.063" W (2.00mm x 1.60mm). However, seated heights vary: VLS201610CX-2R2M-1 is 1.00mm, while BWVC parts are 1.25mm compared to the original 1.20mm. PCB assembly clearance must be verified for applications with height-constrained layouts.

Q: Which substitute should be selected for new designs?

A: VLS201610CX-2R2M-1 is the recommended choice for new designs as it is the active TDK manufacturer substitute with improved electrical performance and confirmed long-term availability. The Pulse Electronics alternatives (BWVC002016122R2M00 and BWVC002016122R2T00) are viable cross-manufacturer options when TDK supply is unavailable or when extended temperature range (-55°C ~ 125°C) is required.

Q: How do DC resistance values affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation. The substitute parts offer 159-163 mOhm compared to the original 195 mOhm, resulting in approximately 18-23% reduction in resistive losses. This improvement enhances thermal performance and efficiency, particularly in high-frequency switching applications.
