Is there a pin-compatible replacement for XL1507-5.0E1?

Currently, no pin-compatible replacement in the same TO-252-5L package has been verified. All reviewed candidates require a PCB layout change due to different package footprints.

What risks should I check before replacing XL1507-5.0E1?

The main risks are package incompatibility, requiring a board redesign, and differences in switching frequency. A lower frequency (e.g., 52kHz vs 150kHz) requires recalculating and replacing the inductor and capacitors to ensure stability and performance.

XL1507-5.0E1 Alternatives, Datasheet & Cross Reference | XLSEMI

XL1507-5.0E1 is a 5V, 3A step-down DC-DC converter in a TO-252-5L package. While no direct pin-compatible replacements are available, several functional alternatives like the LM2596S-5.0 exist but require a board redesign.

AI replacement insight

Package riskhigh

TO-252 and TO-263 packages have different footprints and are not interchangeable.

Electrical riskmedium

Some alternatives have a different switching frequency, which impacts external component selection.

Sourcing risklow

The LM2596 and LM2576 families are widely available from multiple vendors.

Can it be replaced directly?

No direct, pin-compatible replacement has been identified. All suitable alternatives require board layout changes.

Best replacement path

Use LM2596S-5.0, but plan for a PCB respin to accommodate the larger TO-263 package.

Main risk

Package mismatch is the primary risk, making all candidates non-drop-in replacements.

Recommended alternatives

High-voltage version with wider input range and matching frequency, but in a different TO-263 package.
