Use the complete Shark model code from the machine label when checking replacement parts.
Step-by-step check
- Read the label
Check the rating label on the vacuum body or handheld unit. Copy suffix letters as printed; IX140 and a different IX-series code should not be silently merged.
- Check the part
If you have the old filter or attachment, record its part number too. Shark’s 616FJ140 product page lists individual compatible codes.
- Batteries need another check
For BU3120, Shark warns that generations differ. Read the existing battery pack model and voltage rating before choosing XBTR625KSLN.
A real fit-check example
Shark's 616FJ140 filter page names IX140 and several related codes individually. Its 630FJ140 mini brush has a different list. Copying just IX140 as a rough series guess can hide a suffix that changes the answer. For a BU3120 battery, the machine code is only the start: the existing pack model and voltage rating also matter.
Common question
Can a product photo confirm my Shark model?
No. Similar bodies and attachments appear across several models. Use the rating label and manufacturer part page, especially before choosing an electrical component.
