Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252012ET-100M is determined by the following critical parameters:

• Inductance Value: Must be 10 µH with tolerance of ±20% or tighter
• Current Rating: Must support minimum 590 mA continuous current
• DC Resistance (DCR): Must not exceed 756 mOhm to maintain equivalent power dissipation characteristics
• Core Material: Must be ferrite to ensure electromagnetic performance
• Shielding: Must be shielded to maintain EMI containment
• Operating Temperature Range: Must encompass or exceed -40°C to 105°C
• Mounting Type: Must be surface mount compatible
• Physical Dimensions: Must fit within or match the 2.50mm x 2.00mm footprint
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute parts listed below meet these criteria with variations in current saturation ratings, DCR values, and package designations that do not compromise functional equivalence in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain ROHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility with the original VLS252012ET-100M.

VLS252010CX-100M-1 (TDK Corporation, Active): This TDK substitute offers improved current handling at 710 mA with reduced DCR of 580 mOhm, providing lower power dissipation. The part maintains identical operating temperature range and inductance specifications. Height is reduced to 0.039" (1.00mm), which may provide board layout advantages. Product status is Active, ensuring long-term availability.

BWVF00252012100M00 (Pulse Electronics, Active): This Pulse Electronics alternative delivers the lowest DCR at 385 mOhm with 700 mA current rating and extended temperature range (-55°C to 125°C). The nonstandard package designation requires verification of mechanical compatibility despite matching footprint dimensions. Product status is Active.

BWVF00252012100T00 (Pulse Electronics, Active): This Pulse Electronics option maintains the standard 1008 (2520 Metric) package designation, ensuring direct mechanical compatibility. It provides 630 mA current rating with 385 mOhm DCR and extended temperature range (-55°C to 125°C). Inductance tolerance is ±30%, which is wider than the original ±20%. Product status is Active.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-100M-1 directly replace VLS252012ET-100M in all applications?

A: VLS252010CX-100M-1 meets all critical substitution parameters: identical 10 µH inductance, higher current rating (710 mA vs. 590 mA), lower DCR (580 mOhm vs. 756 mOhm), and matching operating temperature range. The reduced height (0.039" vs. 0.047") is compatible with standard PCB assembly processes. Verify that the nonstandard package designation does not conflict with your procurement or assembly specifications.

Q: What is the difference between the Pulse Electronics BWVF parts?

A: BWVF00252012100M00 and BWVF00252012100T00 differ in package designation and inductance tolerance. BWVF00252012100T00 carries the standard 1008 (2520 Metric) package designation, matching the original part's mechanical specification. BWVF00252012100M00 uses a nonstandard package designation but offers identical electrical performance. Both provide extended temperature range (-55°C to 125°C) and low DCR (385 mOhm).

Q: Are there height clearance concerns with substitute parts?

A: VLS252010CX-100M-1 has reduced height (0.039" vs. 0.047"), which is advantageous for compact designs. Both Pulse Electronics parts have increased height (0.049" vs. 0.047"), a 0.002" (0.05mm) difference that is negligible for standard PCB assembly. Verify clearance requirements for your specific application.

Q: Do all substitute parts maintain the same inductance tolerance?

A: VLS252010CX-100M-1 and BWVF00252012100M00 maintain ±20% tolerance matching the original. BWVF00252012100T00 has ±30% tolerance, which is wider. For applications requiring tighter inductance control, VLS252010CX-100M-1 or BWVF00252012100M00 are preferred.

Q: Which substitute offers the best thermal performance?

A: BWVF00252012100M00 and BWVF00252012100T00 provide extended operating temperature range (-55°C to 125°C vs. -40°C to 105°C) and lower DCR (385 mOhm vs. 756 mOhm), resulting in reduced power dissipation and improved thermal characteristics. VLS252010CX-100M-1 offers intermediate DCR (580 mOhm) with standard temperature range.

Q: Are all substitute parts in active production?

A: Yes. VLS252010CX-100M-1, BWVF00252012100M00, and BWVF00252012100T00 all have Active product status, ensuring ongoing availability and supply chain stability. The original VLS252012ET-100M is classified as Not For New Designs.
