Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252010ET-100M is determined by the following critical parameters:

• Inductance Value: Must be 10 µH (fixed requirement)
• Inductance Tolerance: ±20% or tighter acceptable
• Current Rating: Minimum 550 mA required; higher ratings provide design margin
• DC Resistance: Lower values preferred; maximum 854 mOhm acceptable for direct replacement
• Core Material: Ferrite or Iron acceptable (both provide shielding)
• Shielding: Required for EMI performance
• Package Compatibility: 1008 (2520 Metric) preferred; nonstandard packages acceptable if physical dimensions align
• Operating Temperature: Minimum -40°C to 105°C; extended ranges acceptable
• Mounting Type: Surface Mount required
• Compliance: ROHS3 and MSL 1 required

All four substitute parts meet the core inductance, current, and shielding requirements. Variations in DCR, saturation current, and package designation reflect manufacturing differences while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-100M-1 (TDK, Active Status): Direct TDK alternative with improved current rating (710 mA) and reduced DCR (580 mOhm). Maintains ferrite core and identical operating temperature range. Recommended for designs requiring TDK component continuity and enhanced performance margin.

PA4335.103NLT (Pulse Electronics, Active Status): Highest current rating (850 mA) and lowest DCR (480 mOhm) among substitutes. Iron core construction with extended temperature range (-40°C to 125°C) and 14 MHz self-resonant frequency. Suitable for applications requiring maximum current headroom and thermal performance. Physical dimensions slightly larger (2.70 x 2.20 mm, 1.20 mm height).

BWVF00252010100M00 (Pulse Electronics, Active Status): Ferrite core with 700 mA rating and 535 mOhm DCR. Extended operating temperature (-55°C to 125°C). Nonstandard package designation with identical footprint dimensions to original part. Suitable for temperature-critical applications.

BWVF00252010100T00 (Pulse Electronics, Active Status): Ferrite core with standard 1008 (2520 Metric) package designation. 630 mA rating with 535 mOhm DCR and extended temperature range (-55°C to 125°C). Inductance tolerance ±30% (wider than original). Recommended for applications where package standardization is prioritized and tolerance variance is acceptable.

All substitutes maintain ROHS3 compliance and MSL 1 rating. Selection should prioritize active product status and compliance requirements for new production.

Frequently Asked Questions (FAQ)

Q: Can PA4335.103NLT replace VLS252010ET-100M in existing designs?

A: Yes, functionally. The PA4335.103NLT meets all critical electrical parameters (10 µH inductance, 850 mA current rating, shielded). Physical dimensions are slightly larger (2.70 x 2.20 mm vs. 2.50 x 2.00 mm), requiring PCB layout verification. Iron core material differs from ferrite but maintains shielding performance.

Q: What is the difference between "1008 (2520 Metric)" and "Nonstandard" package designations?

A: "1008 (2520 Metric)" is the standardized EIA package designation. "Nonstandard" indicates manufacturer-specific packaging that may not follow standard naming conventions. Physical dimensions remain compatible when footprints match (2.50 x 2.00 mm). Verify with PCB design files before substitution.

Q: Why does BWVF00252010100T00 have ±30% tolerance instead of ±20%?

A: Inductance tolerance reflects manufacturing process specifications. ±30% tolerance is wider but remains within acceptable range for most applications. Verify circuit design margin before substitution if tolerance-sensitive filtering or resonant circuits are involved.

Q: Which substitute offers the best thermal performance?

A: PA4335.103NLT and both BWVF variants support -55°C to 125°C operating range, compared to the original -40°C to 105°C. PA4335.103NLT additionally provides 14 MHz self-resonant frequency specification for high-frequency applications.

Q: Are all substitutes available in production quantities?

A: Yes. VLS252010CX-100M-1 has 537,300 pcs in stock. PA4335.103NLT has 14,924 pcs. BWVF00252010100M00 has 2,652 pcs. BWVF00252010100T00 has 1,101 pcs. Verify current inventory with supplier before design commitment.

Q: What is the primary reason to substitute from VLS252010ET-100M?

A: The original part carries "Not For New Designs" status, indicating TDK has discontinued active support. All four substitutes are Active status components, ensuring long-term availability and manufacturing support for production designs.
