Do not select an LED strip connector by COB/SMD label alone. Confirm strip width, pin count, copper-pad layout, cut-point clearance, connection route and sample fit. Selected 2-pin formats can be shared by COB and SMD when these fields match; 3-pin and 4-pin formats need exact-model confirmation.
What changes between COB and SMD strips?
COB strips use a continuous light-emitting surface, while SMD strips expose individual LED packages. For connector selection, the most important difference is not the lighting effect; it is the geometry near the cut point. The connector must reach the copper pads without being blocked by coating, components or pad spacing.
| Selection field | COB question | SMD question |
|---|---|---|
| Cut point | Is the coating or phosphor layer clear enough for insertion? | Are LED packages close to the pad area? |
| Copper pads | Are the exposed pads long and aligned with the connector contacts? | Do pad spacing and printed polarity match the contact layout? |
| Mechanical clearance | Will the strip enter the channel without surface damage? | Will the housing avoid nearby components? |
| Sample approval | Test the actual COB strip and approved cut point. | Test the exact SMD strip, not only the nominal width. |
Why 2-pin is sometimes shared
In many single-color strips, 2-pin means positive and negative only. If the connector channel, copper pads and insertion depth match, selected ELIX 2-pin formats can serve both COB and SMD strips. This is a model-specific compatibility result, not a universal rule.
Why 3-pin and 4-pin need more care
Multi-channel strips introduce channel sequence, contact spacing and polarity risks. A 10 mm 3-pin COB strip and a 10 mm 3-pin SMD strip can still require different connector geometry. For quotations, separate COB and SMD unless the exact ELIX model has been confirmed for both.
Connector route matters after compatibility
Strip-to-strip
Best for straight extension and repair when no wire lead is required.
Strip-to-wire
Used when the strip needs power input or a cable connection.
L-shape / corner
For cabinet, shelf, channel and display turns where bending the strip is not ideal.
Protected option
Used only when the exact connector or assembly is suitable for the required environment.
What to send VEXIRA
- VEXIRA works as a connector supply-chain partner, helping buyers control selection, samples, documents, packing and logistics.
- COB and SMD compatibility is confirmed by exact model, stable quality and sample approval, not only by strip width.
- Selected in-stock models can be prepared for shipment in as fast as 5 working days after specification confirmation.
- DDP, forwarder and freight-route support can be discussed for the United States, Europe and selected Middle East destinations; timing depends on route and customs conditions.
Not sure if your strip is COB or SMD compatible?
Send the strip type, width, pin count, route and estimated quantity. A clear cut-point image can be added if available. VEXIRA can review the exact ELIX connector path before sampling.
Confirm the ELIX route
Send the strip fields above and VEXIRA can shortlist the compatible model family before sampling.
Frequently asked questions
Can the same 2-pin connector work for COB and SMD?
Yes, for selected models when strip width, copper pads and insertion geometry match. Always confirm with the actual strip.
Should COB and SMD use separate catalog sections?
For clarity, yes. A shared model can still be noted, but buyers should see which strip construction has been confirmed.
Is pin count enough for quotation?
No. Pin count must be combined with width, pad layout, route, electrical requirement and sample confirmation.
