Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252012ET-1R0N is determined by the following criteria:

Primary Substitution Parameters:

• Inductance value: 1 µH (exact match required)
• Core material: Ferrite shielded construction
• Mounting type: Surface Mount
• Physical footprint: 2520 Metric dimensions (0.098" L x 0.079" W)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Performance Compatibility Parameters:

• Current rating must equal or exceed 1.7 A
• DC resistance must not exceed 87 mOhm
• Operating temperature range must encompass -40°C ~ 105°C
• Saturation current (Isat) must support application requirements

The three substitute parts listed below meet these criteria with varying performance enhancements and packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-1R0M-1 (TDK Corporation - Active)

This substitute offers improved current rating (2.29 A vs. 1.7 A) and reduced DC resistance (65 mOhm vs. 87 mOhm). Active product status supports long-term availability. Tighter tolerance (±20%) provides better inductance consistency. Height reduction to 1.00 mm accommodates space-constrained layouts. Packaging as Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume applications.

BWVF002520121R0M00 (Pulse Electronics - Active)

This substitute delivers the highest current rating (2.4 A) and lowest DC resistance (50 mOhm) among alternatives. Extended operating temperature range (-55°C ~ 125°C) supports broader environmental applications. Active product status ensures supply continuity. Nonstandard package designation requires verification of mechanical compatibility with existing PCB layouts.

BWVF002520121R0T00 (Pulse Electronics - Active)

This substitute maintains standard 1008 (2520 Metric) package compatibility with the main part, simplifying PCB redesign requirements. Current rating of 2.16 A and DC resistance of 50 mOhm provide performance improvement. Extended operating temperature range (-55°C ~ 125°C) supports demanding thermal environments. Active product status ensures long-term supply availability. Tape & Reel (TR) packaging matches the main part format.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-1R0M-1 be used as a direct replacement for VLS252012ET-1R0N?

A: VLS252010CX-1R0M-1 meets all electrical substitution criteria with superior current rating and lower DC resistance. However, the nonstandard package designation and reduced height (1.00 mm vs. 1.20 mm) require PCB layout verification. Mechanical fit must be confirmed before implementation.

Q: What is the primary advantage of BWVF002520121R0T00 over other substitutes?

A: BWVF002520121R0T00 maintains the standard 1008 (2520 Metric) package format identical to the main part, minimizing PCB redesign effort. It provides improved electrical performance (2.16 A current rating, 50 mOhm DCR) and extended temperature range (-55°C ~ 125°C).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed—VLS252010CX-1R0M-1, BWVF002520121R0M00, and BWVF002520121R0T00—are ROHS3 Compliant with MSL 1 (Unlimited) rating and REACH Unaffected status.

Q: How do DC resistance differences affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation. BWVF substitutes (50 mOhm) dissipate less power than the main part (87 mOhm) at equivalent current levels. VLS252010CX-1R0M-1 (65 mOhm) provides intermediate performance. Selection depends on thermal budget and efficiency requirements.

Q: What packaging considerations apply to nonstandard package parts?

A: VLS252010CX-1R0M-1 and BWVF002520121R0M00 carry nonstandard package designations. Physical dimensions remain within 2520 Metric footprint (0.098" L x 0.079" W), but height variations (1.00 mm and 1.25 mm respectively) may affect PCB clearance and automated assembly processes. Mechanical verification is required.

Q: Why is the main part marked "Not For New Designs"?

A: VLS252012ET-1R0N carries this designation indicating it is a legacy product. All listed substitutes are Active products, supporting new design implementations and ensuring long-term supply availability.
