Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252010T-100M is determined by the following critical parameters: inductance value (10 µH), tolerance (±20%), shielding requirement (shielded), surface mount configuration, and operating temperature range compatibility. Substitute parts must maintain the same inductance specification and tolerance band. Current rating, saturation current, and DC resistance are secondary parameters that define performance envelope compatibility. All substitute parts listed maintain ROHS3 compliance and surface mount packaging suitable for 1008 (2520 Metric) footprint applications.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-100M-1 (TDK Corporation) is the manufacturer-recommended substitute, maintaining TDK platform continuity with improved current rating (710 mA) and reduced DC resistance (580 mOhm). This part is active in production with ROHS3 compliance. Package designation is nonstandard but physical dimensions remain compatible with 2520 footprint applications.

74438323100 (Würth Elektronik) provides an alternative with AEC-Q200 automotive qualification, extended operating temperature range (-40°C ~ 125°C), and higher saturation current (1.35 A). This part maintains standard 1008 (2520 Metric) package designation with active production status and ROHS3 compliance.

PA4335.103NLT (Pulse Electronics) offers the highest current rating (850 mA) and lowest DC resistance (480 mOhm) with extended temperature range (-40°C ~ 125°C). Iron core construction differs from the ferrite core main part. This part is active in production with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-100M-1 be used as a direct replacement for VLS252010T-100M?

A: Yes. Both parts share identical inductance (10 µH), tolerance (±20%), shielding, and operating temperature range (-40°C ~ 105°C). VLS252010CX-100M-1 provides superior performance with higher current rating and lower DC resistance. Package designation differs (nonstandard vs. standard 1008), but physical dimensions are compatible.

Q: What are the physical dimension differences between substitute parts?

A: VLS252010T-100M and 74438323100 both use standard 1008 (2520 Metric) packaging at 2.50mm L × 2.00mm W × 1.00mm H. VLS252010CX-100M-1 uses nonstandard designation but maintains identical physical dimensions. PA4335.103NLT has slightly larger dimensions at 2.70mm L × 2.20mm W × 1.20mm H.

Q: Which substitute part has the lowest DC resistance?

A: PA4335.103NLT has the lowest DC resistance at 480 mOhm maximum, compared to 854 mOhm for the main part. This reduces power dissipation in current-limited applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (VLS252010CX-100M-1, PA4335.103NLT, and 74438323100) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the temperature range difference between substitute parts?

A: VLS252010T-100M and VLS252010CX-100M-1 operate from -40°C to 105°C. PA4335.103NLT and 74438323100 extend the upper limit to 125°C, providing additional thermal margin for high-temperature applications.
