component identification code 428WP

Gabor1 · ‎2024-02-07

Hi,

Can anyone help me identify the component(s)? What kind of components these and what is the type of package (SSOP8 or TSSOP8)?

Please see the the pictures.

Thank you.

Welcome @Gabor1, to the community!

the marking 428WP stands for the M24128-BWDW6TP in TSSOP8 (169mil), which is already on NRND (Not Recommended for New Design) because of the limited operating voltage range 2.5-5.5V.

The recommended replacement offer identical behaviour and a wider operating voltage range of

1.8-5.5V (M24128-BRDW6TP)
1.7-5.5V (M24128-BFDW6TP)

Does it answer your question?

Regards
