Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS252012CX-1R5M must satisfy the following critical parameters:

• Inductance value of 1.5 µH
• Identical package footprint: 1008 (2520 Metric)
• Shielded construction
• Surface mount configuration
• RoHS3 compliance
• MSL 1 rating

The four Pulse Electronics BWVH series inductors listed below meet these core requirements. Substitution compatibility is determined by matching inductance, package dimensions, shielding type, and compliance certifications. Variations in current rating, DC resistance, and inductance tolerance are secondary parameters that must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

All four Pulse Electronics BWVH series inductors are active products with RoHS3 compliance and MSL 1 ratings, making them suitable replacements from a regulatory and environmental standpoint.

The primary differentiation among substitute options is current rating capacity:

BWVH002520121R5M00 and BWVH002520121R5T00 are rated for 1.6 A continuous current with 75 mOhm DC resistance. These parts are appropriate for applications where the circuit current does not exceed 1.6 A.

BWVH002520121R5MH1 and BWVH002520121R5TH1 are rated for 1.8 A continuous current with 88 mOhm DC resistance. These parts accommodate higher current demands within the 1.8 A range.

The original VLS252012CX-1R5M is rated for 2.3 A. Applications requiring the full 2.3 A rating cannot be directly substituted with any of the listed Pulse Electronics alternatives, as all substitute options have lower current ratings. Circuit redesign or alternative component selection may be necessary for applications with current requirements exceeding 1.8 A.

Inductance tolerance differences (±20% versus ±30%) should be evaluated against circuit specifications. The ±20% tolerance variants (BWVH002520121R5M00 and BWVH002520121R5MH1) provide tighter tolerance matching to the original part.

All substitute parts operate across an extended temperature range (-55°C to 125°C) compared to the original part (-40°C to 105°C), providing broader environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can BWVH002520121R5M00 or BWVH002520121R5T00 be used as direct replacements for VLS252012CX-1R5M?

A: These parts are mechanically and electrically compatible for applications where circuit current does not exceed 1.6 A. Both maintain the 1.5 µH inductance value, identical package footprint, shielded construction, and compliance certifications. The primary limitation is reduced current rating capacity.

Q: What is the difference between BWVH002520121R5M00 and BWVH002520121R5T00?

A: Both parts share identical electrical specifications (1.5 µH, 1.6 A, 75 mOhm). The distinction is inductance tolerance: BWVH002520121R5M00 has ±20% tolerance, while BWVH002520121R5T00 has ±30% tolerance. Select based on circuit tolerance requirements.

Q: What is the difference between BWVH002520121R5MH1 and BWVH002520121R5TH1?

A: Both parts share identical electrical specifications (1.5 µH, 1.8 A, 88 mOhm). The distinction is inductance tolerance: BWVH002520121R5MH1 has ±20% tolerance, while BWVH002520121R5TH1 has ±30% tolerance. Select based on circuit tolerance requirements.

Q: Why do the Pulse Electronics substitutes have lower current ratings than the original TDK part?

A: Current rating is determined by core material, wire gauge, and thermal design. The Pulse Electronics BWVH series inductors are designed with different specifications that result in lower saturation current limits. Applications requiring 2.3 A operation must either use the original TDK part or identify alternative components with matching current specifications.

Q: Are the height differences between the original and substitute parts significant?

A: The original VLS252012CX-1R5M has a maximum seated height of 0.047" (1.20mm), while all Pulse Electronics substitutes have a maximum seated height of 0.049" (1.25mm). This 0.002" (0.05mm) difference is minimal and typically does not impact PCB layout or assembly clearance in standard applications. Verify clearance in designs with tight vertical constraints.

Q: Do all substitute parts meet the same compliance requirements as the original?

A: All four Pulse Electronics BWVH series inductors are RoHS3 compliant with MSL 1 (Unlimited) ratings, matching the original part's compliance profile. All parts are suitable for applications with equivalent environmental and regulatory requirements.

Q: Which substitute part should be selected for new designs?

A: For new designs, select based on circuit current requirements. If current does not exceed 1.6 A, BWVH002520121R5M00 (±20% tolerance) or BWVH002520121R5T00 (±30% tolerance) are appropriate. If current reaches 1.8 A, select BWVH002520121R5MH1 (±20% tolerance) or BWVH002520121R5TH1 (±30% tolerance). Tighter tolerance variants (±20%) are recommended when circuit performance is sensitive to inductance variation.
