Engineering Selection Recommendations

VLS201610CX-6R8M-1 is the manufacturer-recommended primary substitute from TDK Corporation. This part maintains design continuity within the same manufacturer ecosystem while offering improved current rating (790 mA versus 580 mA) and reduced DC resistance (582 mOhm versus 708 mOhm). The part carries Active product status and maintains identical inductance, tolerance, shielding, and core material specifications. Height is reduced to 1.00mm, providing potential PCB layout advantages.

BWVF002016126R8M00 and BWVF002016126R8T00 from Pulse Electronics provide cross-manufacturer alternatives with significantly lower DC resistance (465 mOhm), higher current ratings (700 mA), and extended operating temperature range (-55°C to 125°C). Both parts maintain Active product status and full RoHS3 compliance. The primary distinction between these two Pulse Electronics options is inductance tolerance: BWVF002016126R8M00 specifies ±20% tolerance matching the original part, while BWVF002016126R8T00 specifies ±30% tolerance.

All three substitute parts are electrically and mechanically compatible with the original VLS201612ET-6R8M within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-6R8M-1 be used as a direct replacement for VLS201612ET-6R8M?

A: Yes. Both parts share identical inductance (6.8 µH), tolerance (±20%), shielding, core material, package footprint (2.00mm x 1.60mm), and operating temperature range. VLS201610CX-6R8M-1 exceeds the current rating requirement and provides lower DC resistance, making it a compatible upgrade.

Q: What is the primary advantage of Pulse Electronics BWVF parts over the TDK VLS201610CX-6R8M-1?

A: The BWVF series offers significantly reduced DC resistance (465 mOhm versus 582 mOhm), resulting in lower power dissipation and heat generation. Additionally, the extended operating temperature range (-55°C to 125°C versus -40°C to 105°C) provides broader environmental compatibility.

Q: Should I select BWVF002016126R8M00 or BWVF002016126R8T00?

A: Both parts are electrically and mechanically equivalent. BWVF002016126R8M00 maintains ±20% inductance tolerance matching the original specification. BWVF002016126R8T00 specifies ±30% tolerance. Select based on your circuit's inductance tolerance requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. VLS201610CX-6R8M-1, BWVF002016126R8M00, and BWVF002016126R8T00 are all ROHS3 Compliant with MSL rating of 1 (Unlimited).

Q: What is the height difference between the original part and substitutes?

A: VLS201612ET-6R8M has a seated height of 1.20mm. VLS201610CX-6R8M-1 is reduced to 1.00mm. BWVF parts are 1.25mm. Verify PCB clearance requirements before selection.

Q: Can I use these substitutes in new designs?

A: Yes. All three substitute parts carry Active product status, making them suitable for new design implementations. The original VLS201612ET-6R8M is marked Not For New Designs.
