Engineering Selection Recommendations

Primary Recommendation: VLS201610CX-4R7M-1

The VLS201610CX-4R7M-1 is the direct functional equivalent for the obsolete VLS201610CX-4R7M. Selection of this substitute is based on the following engineering criteria:

1. Product Status Alignment: The substitute part carries Active product status, ensuring long-term availability and continued manufacturing support from TDK Corporation, eliminating supply chain risk associated with the obsolete main part.

2. Electrical Equivalence: All critical electrical parameters—inductance, tolerance, current rating, saturation current, and DC resistance—are identical to the main part, ensuring drop-in compatibility in circuit applications.

3. Compliance Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, satisfying regulatory and environmental requirements without modification to assembly or storage procedures.

4. Mechanical Compatibility: Identical physical dimensions (2.00mm x 1.60mm x 1.00mm) and surface mount configuration ensure compatibility with existing PCB layouts and automated assembly equipment.

5. Packaging Consideration: The substitute is supplied in Cut Tape (CT) and Digi-Reel® formats. Design teams must confirm that existing tape-and-reel handling equipment accommodates these packaging formats. If standard 2-SMD packaging is required, consult TDK Corporation for alternative packaging availability.

Frequently Asked Questions (FAQ)

Q1: Can VLS201610CX-4R7M-1 be used as a direct replacement for VLS201610CX-4R7M in existing designs?

A: Yes. The VLS201610CX-4R7M-1 is electrically and mechanically equivalent across all critical parameters: inductance (4.7 µH), current rating (1 A), DC resistance (365mOhm max), operating temperature (-40°C ~ 105°C), and physical dimensions (2.00mm x 1.60mm x 1.00mm). No circuit modifications are required.

Q2: What is the difference between the main part and the substitute?

A: The primary differences are product status and packaging format. The main part (VLS201610CX-4R7M) is obsolete and supplied in standard 2-SMD packaging. The substitute (VLS201610CX-4R7M-1) is active and supplied in Cut Tape (CT) and Digi-Reel® formats. All electrical and mechanical specifications are identical.

Q3: Are there any temperature or environmental limitations when using the substitute?

A: No. Both parts operate across the identical temperature range (-40°C ~ 105°C) and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Environmental performance is equivalent.

Q4: Does the substitute part meet RoHS compliance requirements?

A: Yes. The VLS201610CX-4R7M-1 is ROHS3 compliant, matching the compliance status of the main part.

Q5: What packaging formats are available for the substitute part?

A: The VLS201610CX-4R7M-1 is supplied in Cut Tape (CT) and Digi-Reel® formats. If alternative packaging is required, contact TDK Corporation directly for availability and lead time information.

Q6: Is the saturation current specification identical between the main part and substitute?

A: Yes. Both parts have a saturation current (Isat) of 820mA, ensuring identical current handling characteristics under saturation conditions.

Q7: Can the substitute part be used in high-frequency applications?

A: Both parts are tested at 1 MHz inductance frequency. Applications requiring operation at frequencies significantly different from 1 MHz should reference the self-resonant frequency specification if available from the manufacturer.
