A charging-port assembly may look like a small, familiar replacement part. On a purchase order, however, “iPhone charging port” is not a sufficiently precise description. Buyers need to know which device variant, which assembly, and which source of compatibility evidence are behind the supplier’s offer. This matters especially when a repair shop orders in quantities rather than one part for a single diagnosed repair.
This worksheet is designed to help a shop send a complete inquiry. It is not a fitment catalog, a list of compatible models, or a claim that any inventory is available.
Begin with the device, not a connector photo
Record the customer-facing model name, the exact model identifier where available, and the market or region variant where that distinction matters. Keep the device intake record separate from the parts inquiry so that private customer details do not leave the shop unnecessarily. If the phone is not accessible, mark an identifier unconfirmed rather than guessing from appearance.
Next, use the relevant manufacturer’s repair documentation to understand how the charging interface is represented. For example, Apple’s iPhone 15 and iPhone 16 repair manuals contain model-specific parts views and a USB-C connector procedure. The existence of those procedures does not mean one model’s component can be installed in another. The procedure, part description and orderable-parts information must be checked for the precise device. Apple iPhone 15 manual · Apple iPhone 16 manual.
A connector’s shared external shape is especially weak evidence of compatibility. USB-C is an interface family; it is not a universal manufacturer replacement-part number. The USB-IF’s cable and connector information discusses cable and connector standards, but does not certify that a particular aftermarket charging-port flex assembly fits a particular phone model.
Determine what the quoted item actually includes
The terms port, connector, charging flex, dock assembly, and replacement kit may describe different product scopes. Ask for a description of the delivered assembly, not just a generic photograph. Depending on a device design, a supplier’s item may include or exclude a flex cable, brackets, microphones, seals or other small parts. Do not assume those items are included merely because another vendor uses a similar name.
For a useful inquiry, request a current image of both sides of the supplied assembly, a readable label or supplier stock number, and a written statement of the device identifiers the supplier supports. If a supplier offers alternative grades or conditions, request their actual definitions and evidence. “Premium” is not a substitute for the seller’s part-identity record.

Make the decision explicit
Use three labels: Confirmed (supported by a document matching the exact offered item), Pending (awaiting the supplier), and Not a match (evidence conflicts). A buyer should not convert “pending” into “confirmed” because a device name appears in a search result.
One practical rule is to pause an order when the device version, assembly contents or supplier item number remains unresolved. That pause is cheaper than a batch of parts a technician cannot responsibly install. Attach the finished sheet to the purchase order so that receiving staff can compare the shipment to the originally approved item.

Next action: Send the completed sheet to the supplier and request a written compatibility confirmation for the exact SKU and device variant before approving a bulk order.
