Renault truck 3P: door and parking switches are not one product
SAP-R201, R202 and R203 all have 3P notes in the catalog, but R203 is a parking switch rather than a door switch.
A search filter for Renault and 3P can return different functions. SAP-R201 and SAP-R202 are door-switch records with their own OE references. SAP-R203 is in the parking-switch category and lists 7422107790, 7423126244 and 7423126236. A pin count is a useful description of the plug, not a product category.
Write the control function first
State whether the buyer needs a door/window control or a parking control. Include a photo of the original icon and the full marking. A supplier should not infer function from the 3P note.
Compare only relevant candidates
Once the function is known, compare the candidate OE and connector with that function’s catalog records. Do not put R203 into a door-switch quotation merely because it passes a brand-and-pin search.
Separate inventory families
Use distinct receiving labels and stock bins for door and parking switches. If the original part is unidentified, obtain a qualified identification before issuing a bulk PO.
Purchasing guidance, not installation or diagnostic instructions. Confirm compatibility and specifications with the supplier and a qualified technician.
