Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS3010ET-2R2M are qualified based on the following criteria:

Electrical Parameters (Primary):

• Inductance value: 2.2 µH (±20% tolerance acceptable)
• Shielding requirement: Shielded construction mandatory
• Operating temperature range: Minimum -40°C ~ 105°C coverage required
• Inductance test frequency: 1 MHz

Mechanical Parameters (Secondary):

• Mounting type: Surface Mount only
• Package footprint: 3.00mm x 3.00mm (0.118" x 0.118")
• Height constraint: Maximum seated height ≤ 1.20mm for PCB clearance compatibility

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited) acceptable

Current rating, DC resistance, and saturation current are application-dependent and may vary between substitutes while maintaining electrical functionality. Substitute parts meeting all primary and mechanical parameters are considered compatible alternatives.

Parameter Comparison

Engineering Selection Recommendations

VLS3012CX-2R2M-1 (TDK Corporation): This substitute maintains TDK manufacturer continuity and is classified as Active product status, ensuring long-term availability. It provides superior current rating (2.83 A vs. 1.2 A) and lower DC resistance (74mOhm vs. 116mOhm), offering improved thermal performance. Operating temperature range matches the original specification. Height increases to 1.20mm maximum, requiring PCB layout verification for clearance compatibility. Recommended for applications prioritizing thermal efficiency and extended current headroom.

BWVF003030102R2M00 (Pulse Electronics): This substitute offers Active product status with extended operating temperature range (-55°C ~ 125°C), providing broader environmental coverage than the original part. Current rating (1.4 A) and DC resistance (100mOhm) closely align with the VLS3010ET-2R2M specifications. Height (1.02mm) remains within tight PCB constraints. Recommended for applications requiring temperature extremes or cross-manufacturer qualification.

BWVF003030102R2T00 (Pulse Electronics): This substitute provides Active product status with extended temperature range (-55°C ~ 125°C). Current rating (1.26 A) and DC resistance (100mOhm) are comparable to the original part. Inductance tolerance widens to ±30%, which may impact circuit performance in precision applications. Height (1.02mm) maintains PCB compatibility. Recommended only when BWVF003030102R2M00 is unavailable and tolerance relaxation is acceptable.

Frequently Asked Questions (FAQ)

Q: Can VLS3012CX-2R2M-1 directly replace VLS3010ET-2R2M in all applications?

A: VLS3012CX-2R2M-1 meets all electrical and mechanical substitution criteria. However, the increased height (1.20mm vs. 1.00mm) requires verification of PCB clearance. The superior current rating and lower DC resistance may alter circuit thermal characteristics; thermal analysis is recommended for power-sensitive applications.

Q: What is the difference between the two Pulse Electronics substitutes?

A: Both BWVF003030102R2M00 and BWVF003030102R2T00 share identical footprint and height specifications. The primary difference is inductance tolerance: BWVF003030102R2M00 maintains ±20% tolerance matching the original part, while BWVF003030102R2T00 relaxes to ±30%. Select BWVF003030102R2M00 for precision circuits; BWVF003030102R2T00 is acceptable only when tolerance relaxation does not impact circuit performance.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes—VLS3012CX-2R2M-1, BWVF003030102R2M00, and BWVF003030102R2T00—are ROHS3 Compliant with MSL rating 1 (Unlimited), matching the original part's compliance profile.

Q: Does the extended temperature range of Pulse Electronics parts affect compatibility?

A: The extended operating temperature range (-55°C ~ 125°C) of Pulse Electronics substitutes is a superset of the original specification (-40°C ~ 105°C). This provides additional environmental margin and does not negatively impact compatibility. Applications operating within the original temperature range experience no functional change.

Q: Which substitute should I select for new designs?

A: All three substitutes carry Active product status, ensuring long-term supply. VLS3012CX-2R2M-1 maintains TDK manufacturer continuity. BWVF003030102R2M00 offers the closest electrical match with extended temperature coverage. Selection depends on supply chain preference, thermal requirements, and PCB layout constraints.
