VLS201612ET-3R3M Equivalent & Substitute Parts

Part Overview

The VLS201612ET-3R3M is a 3.3 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 790 mA with a maximum DC resistance of 357 mOhm. This surface mount component operates across -40°C to 105°C and is packaged in a nonstandard 2.00mm × 1.60mm form factor. The part is classified as "Not For New Designs," indicating it has been superseded in TDK's product portfolio. Identifying equivalent and substitute parts is necessary for ongoing production support, legacy system maintenance, and design flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS201612ET-3R3M is determined by the following critical parameters:

• Inductance Value: Must be 3.3 µH with tolerance of ±20% or tighter
• Current Rating: Must support minimum 790 mA continuous current
• DC Resistance: Must not exceed 357 mOhm to maintain equivalent power dissipation characteristics
• Core Material: Must be ferrite to ensure electromagnetic performance
• Shielding: Must be shielded to prevent EMI coupling
• Package Footprint: Must accommodate 2.00mm × 1.60mm mounting area
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status
• Operating Temperature: Must support at least -40°C to 105°C range

All four substitute parts meet these core substitution criteria. Variations in current saturation ratings, height profiles, and extended temperature ranges represent design improvements or alternative configurations within the same functional class.

Parameter Comparison

Engineering Selection Recommendations

VLS201610CX-3R3M-1 (TDK Corporation, Active Status): This is the manufacturer-recommended successor from TDK's active product line. It provides superior current handling (1.2 A vs. 790 mA) and lower DC resistance (253 mOhm vs. 357 mOhm), resulting in reduced power dissipation. Height is reduced to 1.00mm, offering improved PCB density. Maintains identical operating temperature range and inductance specifications. Recommended for new designs and direct replacement in existing applications.

ASPI-2010-3R3M-T (Abracon LLC, Active Status): Provides current rating of 980 mA with DC resistance of 335 mOhm, closely matching the original part's electrical performance. Extends operating temperature range to -40°C to 125°C, offering improved thermal margin. Height is 1.00mm. Suitable for applications requiring alternative sourcing or where Abracon supply chain is preferred.

BWVC002016123R3M00 and BWVC002016123R3T00 (Pulse Electronics, Active Status): Both variants deliver 950 mA current rating with significantly lower DC resistance of 220 mOhm, providing superior thermal performance. Extended operating temperature range of -55°C to 125°C accommodates wider environmental conditions. Height is 1.25mm. BWVC002016123R3T00 features ±30% inductance tolerance versus ±20% for the M variant. Suitable for applications prioritizing low power dissipation and extended temperature operation.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-3R3M-1 be used as a direct replacement for VLS201612ET-3R3M?

A: Yes. Both parts share identical inductance (3.3 µH), tolerance (±20%), footprint (2.00mm × 1.60mm), operating temperature range (-40°C to 105°C), and compliance certifications. VLS201610CX-3R3M-1 exceeds the original part's current rating and provides lower DC resistance, making it functionally superior for direct substitution.

Q: What is the impact of different DC resistance values on circuit performance?

A: DC resistance directly affects power dissipation and thermal behavior. Lower DC resistance (220-253 mOhm in substitutes vs. 357 mOhm in original) reduces I²R losses, lowering operating temperature and improving efficiency. This is beneficial in power-sensitive applications but does not affect inductance value or frequency response.

Q: Are there height constraints that would prevent substitution?

A: The original part is 1.20mm tall. VLS201610CX-3R3M-1 and ASPI-2010-3R3M-T are 1.00mm (lower profile), while BWVC variants are 1.25mm (higher profile). Verify PCB clearance and component stacking requirements before selection. Lower-profile substitutes offer improved density; higher-profile variants require clearance verification.

Q: Does inductance tolerance affect substitution suitability?

A: All substitutes maintain ±20% tolerance except BWVC002016123R3T00 (±30%). For applications with tight inductance requirements, ±20% tolerance variants are preferred. The ±30% variant is suitable for applications with broader inductance tolerance specifications.

Q: What is the significance of extended temperature ranges in substitute parts?

A: Substitute parts rated to -55°C to 125°C or -40°C to 125°C provide thermal margin beyond the original -40°C to 105°C specification. This is advantageous in automotive, industrial, or high-altitude applications experiencing wider temperature extremes, but not required for standard commercial temperature environments.

Q: Are all substitute parts available in tape and reel packaging?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, maintaining supply chain compatibility with the original part's packaging format.
