Fengming
Strong electrical match with same voltage and SPL, but is 1mm taller and produces a different tone.
Find and compare replacements for the Fengming YS-MBZ12085C05R42, a 5V passive magnetic buzzer. This guide analyzes alternatives based on electrical and mechanical compatibility.
Voltage, current, and resistance are well-matched.
The best alternative is 1mm taller, requiring a mechanical clearance check.
There are no perfect drop-in replacements available. The closest match, YS-MBZ12095C05R42K2700, has a different audible tone and is slightly taller.
YS-MBZ12095C05R42K2700 is the best available option, offering a strong electrical match.
The primary risk is the change in audible frequency (tone) from 2048Hz to 2700Hz, which may not be acceptable for the end application.
