Is there a pin-compatible replacement for CYA1265-6.8UH?

No pin-to-pin verified replacement has been identified. Candidates in similar packages, like MWSA1206S-6R8MT, have different dimensions and significantly lower current ratings, requiring careful layout and electrical validation.

What risks should I check before replacing CYA1265-6.8UH?

Key risks include package size mismatch requiring a new layout, lower saturation current (Isat) causing saturation in high-current applications, and higher DC resistance (DCR) leading to increased power loss and heat.

CYA1265-6.8UH Alternatives, Datasheet & Cross Reference | SHOU HAN

CYA1265-6.8UH is a 6.8µH shielded power inductor in a 1265 package, rated for 28A saturation current. While no direct drop-in replacements have been verified, several functional and parametric alternatives exist that require engineering review.

AI replacement insight

Electrical riskhigh

Alternatives in a similar package have much lower current ratings.

Package riskhigh

Electrically comparable parts are in different, larger packages.

Firmware risklow

Inductors are passive components and do not have firmware.

Can it be replaced directly?

No direct, drop-in replacement for CYA1265-6.8UH is available. All known alternatives require either PCB layout changes or accepting significant electrical performance downgrades.

Best replacement path

For new designs, consider the electrically superior but larger SMMS1770-6R8M. For existing boards, MWSA1206S-6R8MT is a high-risk downgrade that requires thorough testing.

Main risk

The primary risk is finding a part that matches both the 1265 package footprint and the high 28A saturation current of the original.

Recommended alternatives

A functional alternative with higher current ratings and lower resistance, but in a larger 1770 package that is not form-fit compatible.
