alarm output can not be ordered for LA ICK 15 x 15 used fans: 

5 volt = Sepa MFB 40 D 05 H 12 volt = Sepa MFB 40 D 12 H 

– integrated retaining spring fixes the fan cooler safely on the IC – good heat transition ensured by inserted adherent thermalling conductive foil – easy assembly and exchange of fan by insertion into integrated retaining device

About Novapart

Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
