Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS2010ET-4R7M are qualified based on the following electrical and mechanical parameters:

• Inductance value: 4.7 µH (exact match required)
• Inductance tolerance: ±20% (matching tolerance band)
• Shielding: Shielded construction
• Mounting type: Surface mount
• Operating temperature range: Minimum -40°C to 105°C coverage
• RoHS3 compliance
• Moisture sensitivity level: MSL 1

Current rating, DC resistance, and saturation current are allowed to vary within acceptable ranges for the application, provided the substitute meets or exceeds the minimum current handling requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

VLS201610CX-4R7M-1 is the primary recommended substitute. This TDK Corporation part maintains active product status and provides superior electrical performance with 1 A current rating and lower DC resistance of 365 mOhm compared to the original 408 mOhm specification. The part meets all compliance requirements including ROHS3 and MSL 1 ratings. The operating temperature range of -40°C to 105°C matches the original specification.

MDKK2020T4R7MM from Taiyo Yuden serves as a secondary alternative. This part carries "Not For New Designs" status similar to the original component but offers extended operating temperature coverage to 125°C and improved current saturation at 1.05 A. DC resistance of 435 mOhm remains within acceptable tolerance for most applications. ROHS3 and MSL 1 compliance are maintained.

Both substitutes are ROHS3 compliant and carry MSL 1 ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-4R7M-1 directly replace VLS2010ET-4R7M in existing designs?

A: Yes. Both parts share identical inductance (4.7 µH), tolerance (±20%), shielding, operating temperature range (-40°C to 105°C), and compliance certifications. The substitute provides higher current rating (1 A vs. 700 mA) and lower DC resistance (365 mOhm vs. 408 mOhm), making it electrically superior for the same application.

Q: What are the physical differences between these parts?

A: VLS2010ET-4R7M and MDKK2020T4R7MM both measure 2.00mm x 2.00mm with 1.00mm maximum seated height. VLS201610CX-4R7M-1 measures 2.00mm x 1.60mm with the same 1.00mm height, resulting in a slightly narrower footprint.

Q: Are there packaging differences to consider?

A: VLS2010ET-4R7M is supplied in Tape & Reel (TR) packaging. VLS201610CX-4R7M-1 is available in Cut Tape (CT) & Digi-Reel® format. MDKK2020T4R7MM uses Tape & Reel (TR) packaging. Packaging selection depends on production volume and handling requirements.

Q: Why is VLS201610CX-4R7M-1 recommended over MDKK2020T4R7MM?

A: VLS201610CX-4R7M-1 maintains active product status, ensuring long-term availability and supply chain stability. Both parts meet electrical requirements, but the TDK part offers better DC resistance performance and is the manufacturer-recommended upgrade path.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three inductors are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and operate within the required temperature specifications for standard industrial applications.
