VLS252010T-R47N Equivalent & Substitute Parts

Part Overview

The VLS252010T-R47N is a 470 nH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 2.3 A continuous current with a maximum DC resistance of 48 mOhm. This surface mount component in 1008 (2520 Metric) package is designed for high-frequency filtering and impedance matching applications. The part is classified as Obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, core shielding characteristics, and surface mount compatibility while meeting or exceeding electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252010T-R47N is determined by the following critical parameters:

• Inductance Value: Must be 470 nH (±20% to ±30% tolerance acceptable)
• Core Type & Shielding: Must be shielded drum core wirewound construction to maintain electromagnetic isolation
• Current Rating: Must meet or exceed 2.3 A continuous current requirement
• DC Resistance: Lower DCR values indicate improved performance and are acceptable substitutes
• Package Compatibility: Surface mount 1008 (2520 Metric) or equivalent footprint
• Operating Temperature: Must support -40°C ~ 105°C minimum range
• Compliance: ROHS3 compliance required; REACH status preferred

Three substitute parts meet these criteria with varying performance enhancements and availability status.

Parameter Comparison

Engineering Selection Recommendations

VLS252010ET-R47N (TDK Corporation, Not For New Designs): This direct TDK equivalent provides marginal performance improvement with 2.5 A current rating and 46 mOhm DCR. Identical package dimensions and temperature range ensure mechanical and thermal compatibility. Product status designation limits suitability to legacy system maintenance only.

VLS252010CX-R47M-1 (TDK Corporation, Active): This manufacturer-recommended substitute offers superior electrical performance with 3.22 A current rating, 38 mOhm DCR, and tighter ±20% inductance tolerance. Active product status ensures long-term availability. Nonstandard package designation requires footprint verification despite matching 2520 metric dimensions. Recommended for new designs and production transitions.

PA4335.471NLT (Pulse Electronics, Active): This alternative provides the highest current rating (3.45 A) and lowest DCR (35 mOhm) with extended operating temperature range to 125°C. Iron core construction differs from ferrite alternatives. Slightly larger footprint (0.106" L x 0.087" W, 1.20mm height) requires PCB layout verification. Active status and REACH compliance support long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can VLS252010ET-R47N directly replace VLS252010T-R47N in existing designs?

A: Yes, for legacy system maintenance. Both parts share identical package dimensions (1008/2520 Metric), inductance value (470 nH), operating temperature range (-40°C ~ 105°C), and compliance certifications. The ET variant provides slightly improved current rating (2.5 A vs 2.3 A) and lower DCR (46 mOhm vs 48 mOhm). However, the Not For New Designs status limits this option to repair and replacement applications only.

Q: What are the key differences between ferrite and iron core substitutes?

A: VLS252010T-R47N, VLS252010ET-R47N, and VLS252010CX-R47M-1 use ferrite cores, while PA4335.471NLT uses an iron core. Iron core construction in the PA4335.471NLT delivers superior current handling (3.45 A vs 2.3 A) and lower DC resistance (35 mOhm vs 48 mOhm), with a documented self-resonant frequency of 89 MHz. Core material selection affects electromagnetic characteristics and should be evaluated against specific circuit requirements.

Q: Are there footprint compatibility concerns with substitute parts?

A: VLS252010ET-R47N and VLS252010CX-R47M-1 maintain identical footprints to the original (2.50mm L x 2.00mm W x 1.00mm height). PA4335.471NLT has a slightly larger footprint (2.70mm L x 2.20mm W x 1.20mm height) and requires PCB layout verification before implementation. All three maintain surface mount compatibility.

Q: Which substitute is recommended for new product designs?

A: VLS252010CX-R47M-1 is the manufacturer-recommended substitute with Active product status, ensuring long-term availability and supply chain stability. It provides superior electrical performance (3.22 A current rating, 38 mOhm DCR, ±20% tolerance) while maintaining compatibility with the original package footprint.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original VLS252010T-R47N specifications. VLS252010CX-R47M-1 and PA4335.471NLT include REACH Unaffected status, providing additional regulatory assurance for international applications.
