Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS252012ET-2R2M are qualified based on the following electrical and mechanical compatibility criteria:

Primary Matching Parameters:

• Inductance value: 2.2 µH (±20% tolerance acceptable)
• Core material: Ferrite shielded construction
• Mounting type: Surface Mount
• Physical footprint: 2.50mm × 2.00mm base dimensions
• Current rating: Equal to or greater than 1.3 A
• DC resistance: Lower or equal to 154 mOhm preferred for thermal performance
• Operating temperature range: Minimum -40°C to 105°C coverage
• Compliance: ROHS3 and REACH requirements maintained

The substitute parts listed below meet these criteria while offering improvements in current capacity, reduced DC resistance, or enhanced temperature range coverage. Packaging format variations (Tape & Reel vs. Cut Tape) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-2R2M-1 (TDK Corporation - Active Status)

This TDK substitute offers improved current capacity (1.58 A vs. 1.3 A) and reduced DC resistance (126 mOhm vs. 154 mOhm), resulting in lower thermal dissipation. It maintains identical inductance, tolerance, temperature range, and physical footprint compatibility. The Active product status ensures continued availability and manufacturing support. This part is the preferred direct replacement within the TDK product family.

BWVF002520122R2M00 (Pulse Electronics - Active Status)

This Pulse Electronics alternative provides the highest current capacity (1.8 A) and lowest DC resistance (80 mOhm) among all substitutes, enabling superior thermal performance in current-limited applications. The extended operating temperature range (-55°C to 125°C) exceeds the original specification. Physical height increases to 1.25mm; verify PCB clearance before implementation. Active product status guarantees supply continuity.

BWVF002520122R2T00 (Pulse Electronics - Active Status)

This Pulse Electronics option maintains the standard 1008 (2520 Metric) package designation and offers 1.62 A current rating with 80 mOhm DC resistance. The inductance tolerance widens to ±30%, and physical height increases to 1.25mm. Extended temperature range (-55°C to 125°C) is provided. This part balances performance improvements with package standardization.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-2R2M-1 be used as a direct replacement for VLS252012ET-2R2M?

A: Yes. Both parts share identical inductance (2.2 µH), tolerance (±20%), operating temperature range (-40°C to 105°C), and physical footprint (2.50mm × 2.00mm × 1.00mm). The substitute offers improved electrical performance with higher current capacity (1.58 A vs. 1.3 A) and lower DC resistance (126 mOhm vs. 154 mOhm). Packaging format differs (Tape & Reel vs. Cut Tape), but this does not affect electrical or mechanical compatibility.

Q: What are the physical height differences among substitute parts?

A: The original VLS252012ET-2R2M and substitute VLS252010CX-2R2M-1 both have a maximum seated height of 1.00mm. The Pulse Electronics substitutes (BWVF002520122R2M00 and BWVF002520122R2T00) have a maximum seated height of 1.25mm. Verify PCB layout and component clearance before selecting parts with increased height.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—VLS252010CX-2R2M-1, BWVF002520122R2M00, and BWVF002520122R2T00—are ROHS3 compliant with MSL Level 1 rating and REACH unaffected status, matching the original component's regulatory requirements.

Q: Which substitute offers the best thermal performance?

A: BWVF002520122R2M00 provides the lowest DC resistance at 80 mOhm (compared to 154 mOhm in the original), resulting in minimal resistive heating. This part also supports the highest continuous current rating (1.8 A) and extended temperature range (-55°C to 125°C).

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

A: BWVF002520122R2M00 uses a nonstandard package designation, while BWVF002520122R2T00 maintains the standard 1008 (2520 Metric) package format. Both offer identical DC resistance (80 mOhm) and similar current ratings (1.8 A vs. 1.62 A). BWVF002520122R2T00 is preferred if package standardization is required for procurement or assembly processes.

Q: Can these inductors be used in high-temperature applications?

A: The original VLS252012ET-2R2M operates to 105°C maximum. Both Pulse Electronics substitutes (BWVF002520122R2M00 and BWVF002520122R2T00) extend the upper operating limit to 125°C and lower limit to -55°C, providing enhanced thermal range coverage for demanding environments.

Q: Is inductance tolerance a consideration when selecting a substitute?

A: Yes. The original part and most substitutes specify ±20% inductance tolerance. BWVF002520122R2T00 specifies ±30% tolerance, which may affect circuit performance in applications with tight inductance requirements. Verify tolerance requirements against circuit design specifications before selection.
