Is there a pin-compatible replacement for SLF6045T-100M1R6-3PF?

Yes, several parts like CR6045H-100M and VLS6045EX-100M-H use the same 6045 package and are considered pin-compatible. However, you must review their electrical differences, especially the DC Resistance (DCR), before dropping them in.

What risks should I check before replacing SLF6045T-100M1R6-3PF?

Key risks include: 1) Higher DC Resistance (DCR) causing lower efficiency and more heat. 2) Different inductance values altering circuit behavior. 3) Mismatched package sizes requiring a new PCB layout. 4) Lower current ratings which can lead to failure.

SLF6045T-100M1R6-3PF is a 10µH shielded power inductor in a 6045 package. When seeking replacements, focus on matching the 10µH inductance, 6045 package, and ensuring current ratings (Isat/Irise ≥ 1.6A) and DCR (≤ 39mΩ) meet or exceed original specs for optimal performance.

AI replacement insight

Electrical riskmedium

Most alternatives have higher DCR, impacting efficiency and thermals.

Package risklow

Several candidates match the 6045 package, but others require a redesign.

Sourcing risklow

Multiple vendors offer similar parts in this category.

Can it be replaced directly?

No perfect drop-in replacement is identified. VLS6045EX-100M-H is a strong candidate in the same package but has slightly higher DCR. CR6045H-100M is also a strong option with higher current ratings but also higher DCR.

Best replacement path

VLS6045EX-100M-H offers a significant upgrade in current handling and is AEC-Q200 qualified, with only a minor increase in DCR.

Main risk

The main risk is increased DC resistance (DCR) in most alternatives, which leads to lower efficiency and more heat. Alternatives with different packages or inductance require board redesign.

Recommended alternatives

A potential upgrade with higher current ratings (4.5A Isat) in the same 6045 package, but review the increased DCR for efficiency impact.
