Engineering Selection Recommendations

VLS3012CX-6R8M-1 (TDK Corporation)

This substitute maintains TDK Corporation manufacturing continuity with Active product status. It shares identical inductance, tolerance, operating temperature range, and physical dimensions with the main part. Current and DC resistance specifications are not provided; verification against application requirements is necessary before selection.

BWVF003030126R8M00 (Pulse Electronics)

This substitute offers higher current rating (1.17 A) and saturation current (1.18 A) compared to the main part, with extended operating temperature range (-55°C to 125°C). DC resistance is 250 mOhm, exceeding the main part specification by 22 mOhm. Active product status supports long-term availability. Inductance tolerance remains ±20%.

BWVF003030126R8T00 (Pulse Electronics)

This substitute provides identical electrical performance to BWVF003030126R8M00 with inductance tolerance of ±30%, representing a wider tolerance band. Current rating, saturation current, and operating temperature range match BWVF003030126R8M00. Active product status ensures continued supply.

NRH3012T6R8MN (Taiyo Yuden)

This substitute matches the main part in inductance, tolerance, DC resistance, and physical dimensions. Current rating is 890 mA, exceeding the main part by 80 mA. Operating temperature range is -25°C to 120°C, which covers the main part specification. Product status is "Not For New Designs," limiting suitability for new design implementations. Inductance test frequency is 100 kHz rather than 1 MHz.

Frequently Asked Questions (FAQ)

Q: Can VLS3012CX-6R8M-1 directly replace VLS3012ET-6R8M?

A: VLS3012CX-6R8M-1 shares the same inductance value, tolerance, operating temperature range, and physical footprint. However, current rating and DC resistance are not specified for this part. Electrical performance verification is required before substitution in current-sensitive applications.

Q: What is the difference between BWVF003030126R8M00 and BWVF003030126R8T00?

A: Both parts are electrically identical with 1.17 A current rating and 250 mOhm DC resistance. The primary difference is inductance tolerance: BWVF003030126R8M00 specifies ±20%, while BWVF003030126R8T00 specifies ±30%. Selection depends on tolerance requirements for the application.

Q: Why does NRH3012T6R8MN have a different inductance test frequency?

A: NRH3012T6R8MN is tested at 100 kHz, while VLS3012ET-6R8M is tested at 1 MHz. Inductance values can vary with frequency due to core material characteristics. This difference may affect performance in applications sensitive to frequency-dependent inductance behavior.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the main part specification.

Q: Which substitute has the best long-term availability?

A: BWVF003030126R8M00 and BWVF003030126R8T00 both carry Active product status, indicating ongoing manufacturing and supply. VLS3012CX-6R8M-1 and NRH3012T6R8MN are Active and Not For New Designs respectively, with VLS3012CX-6R8M-1 offering better long-term support.

Q: Can I use a substitute with higher DC resistance?

A: BWVF003030126R8M00 and BWVF003030126R8T00 specify 250 mOhm DC resistance, compared to 228 mOhm maximum for the main part. The 22 mOhm increase may impact thermal performance and power dissipation. Application-specific thermal analysis is required to determine acceptability.

Q: Do all substitutes fit the same PCB footprint?

A: Yes. All substitute parts maintain the 3.00mm x 3.00mm footprint with 1.20mm maximum seated height, ensuring mechanical compatibility with existing PCB layouts designed for VLS3012ET-6R8M.
