Replacing a Discontinued Shade Component: Requalification Planning
Plan physical, electrical, control and documentation requalification before replacing a discontinued motorized-shade component.
Direct answer
What should the buyer do?
A possible alternative is not an approved replacement. First identify the installed component and interfaces. Then compare physical fit, mounting, shaft/tube, voltage, current/power, connector, protocol, controller/gateway, limits, remotes, feedback, firmware, service access and documentation. Test the selected assembly before approval.
Why this matters
Matching a model number fragment or voltage can miss mechanical, connector, programming or feedback differences. Requalification records what changed and who accepted the result.
Replacement Requalification Matrix
| Stage | Question | Allowed result |
|---|---|---|
| Identification | What exact component/version is installed? | CONFIRMED / UNKNOWN |
| Possible alternative | Which current item is being considered and why? | CANDIDATE only |
| Physical review | Fit, mounting, shaft/tube/interface and access | MATCH / DEVIATION |
| Electrical review | Voltage, current/power, connector and supply | Qualified review required |
| Control review | Protocol, controller/gateway, remote, feedback, firmware | Selected documents required |
| Test | Representative assembly and applicable functions | NOT_TESTED / PASS / FAIL |
| Approval | Named configuration, revision and authority | PENDING / APPROVED |
Information to collect
- Original order/opening/model
- Installed label and safe photos
- Candidate alternative documentation
- Mechanical/electrical/control deltas
- Test scope and result
- Approval owner and updated references
What Saiwenna can review
Saiwenna can help identify supplied components and compare documented candidate information. Availability and approval remain separate from identification.
No specific substitute is recommended here. Catalog presence, equal voltage or visual similarity does not prove compatibility or current availability.
