Choosing an electronic connector is not only a price comparison. For OEM projects, the connector affects signal stability, assembly yield, mechanical reliability and long-term supply. A clear RFQ helps the supplier check the right series quickly and reduces back-and-forth communication.
1. Define connector type and application environment
Before asking for price, the buyer should identify whether the project needs a board-to-board connector, LVDS connector, floating connector, USB Type-C connector, push-locking connector or another custom interface. The application environment also matters because automotive, consumer electronics and industrial devices may have different vibration, assembly and reliability requirements.
For compact electronic devices, start with Weicheng's Board-to-Board Connectors. For display and signal cable applications, review Low Voltage Differential Signaling Connectors.

Connector selection should match board space, signal requirement, mating method and production volume.
2. Confirm pitch, pin count and mechanical structure
Pitch, pin count, stack height, mating direction and locking structure are often the first technical filters. If the buyer only provides a connector photo, the supplier may not know whether the project requires the same dimension, the same electrical rating or only a similar function. Attach drawings, 3D files or a sample if available.
| RFQ item | What to confirm |
| Connector specification | Pitch, pin count, stack height, mating height, orientation and locking method. |
| Electrical requirement | Current, voltage, signal type, impedance or high-speed transmission requirement. |
| Production need | Sample quantity, annual forecast, packing, SMT process and qualification requirement. |
3. Check signal, reliability and qualification requirements
For OEM electronics, the connector must pass more than dimensional matching. Buyers should confirm current rating, insulation resistance, contact resistance, durability, operating temperature, vibration requirement and any environmental compliance needs. If the connector is used in high-speed or automotive applications, the qualification scope should be discussed early.
For automotive and high-speed signal projects, buyers can compare Automotive HighSpeed Ethernet Connectors and Floating Board-to-Board Connectors.

Board-to-board connector RFQs should include pitch, pin count, mating height and reliability requirements.
4. Compare suppliers by engineering response and supply stability
For connector projects, response speed and technical matching can be more important than a small price difference. Ask whether the supplier can review drawings, provide samples, support cross-reference checks and explain lead time for mass production. For OEMs, stable supply and consistent quality reduce the risk of production interruption.

FAQ
Can Weicheng quote from a connector photo?
A photo can help identify the general type, but drawings, dimensions, pitch, pin count and application requirements are needed for reliable model selection.
What information is most important for board-to-board connectors?
Pitch, pin count, mating height, board space, current rating and production quantity are the most important starting points.
Should annual forecast be included?
