43045-0400 Rectangular Connectors - Contacts by Molex

Defines the contact gender and style, such as pin (male) or socket (female). This determines how the connector mates with its counterpart. Ensure the contact type matches your cable or board connector to avoid mismating. Refer to the datasheet for contact material and plating.

Lists the product categories or classifications assigned to this component, such as connectors, capacitors, or modules. This helps in filtering and comparing similar parts. Review the categories to ensure the component fits your application and to find alternative parts in the same class.

Identifies the company that designed and produced the component. Buyers often filter by manufacturer to ensure brand reliability, quality standards, and supply chain consistency. Verify the manufacturer against the datasheet and official packaging to avoid counterfeit parts.

Indicates the specific product subcategories or classifications within the broader component family. Helps narrow down search results and identify the exact type of component needed for your design. Review the subcategory to ensure compatibility with your application.

Physical package or case type of the component, defining its dimensions, mounting style, and thermal characteristics. Common types include SMD, through-hole, BGA, and QFN. Choose the package that fits your PCB layout and assembly process. Verify the exact package code in the datasheet for footprint compatibility.

The unique part number assigned by the original component manufacturer. Use this to cross-reference datasheets, verify specifications, and ensure the exact component matches your design requirements. Always confirm the number against the manufacturer's official documentation.

The center-to-center distance between adjacent contacts in a connector. Pitch determines the connector's size and PCB footprint requirements. Smaller pitch allows higher density but may require more precise manufacturing. Verify pitch matches your board layout and mating connector to ensure reliable connections.

Specifies the connector series or family, such as USB, RJ45, or D-Sub. This determines mechanical compatibility, pin layout, and mating standards. Verify against the datasheet to ensure the connector matches your board design and mating counterpart.

Specifies the center-to-center distance between rows of contacts in a multi-row connector. This dimension is critical for PCB layout and mating with standard headers. Verify against the datasheet to ensure compatibility with your board design and connector housing.
