Who uses “USCAR” Specifications & Why?
WHO: Anyone can use a USCAR design or spec but they were established for Ford, GM, and FCA US to share common parts and test methods.
Connector and Terminal Suppliers will often choose to make parts compliant to USCAR specifications, knowing that there is a good chance of selling the part to more than a single OEM. Also, device and electronic module suppliers may choose to use a USCAR, to assure their connection is a recognized design.
WHY: The most often given reasons for using USCAR designs are:
Can I order parts directly from EWCAP?
No. EWCAP is not a manufacturer. We do not sell any parts or give quotes on parts. In some cases, we will list which suppliers make a connector that mates to a USCAR footprint to allow you to get a quote.
What USCAR specifications are offered and how do I order them?
EWCAP manages specifications related to our charter for electrical wiring. Connectors, wire, and related parts are controlled by EWCAP.
EWCAP uses SAE to publish and distribute specifications. Go to the SAE store website to purchase a specification (http://store.sae.org/) and searh for the pec you are interested in. Specifications are available for a nominal price. Connector drawings are available on the EWCAP webpage (http://www.uscar.org/guest/teams/10/Electrical-Wiring-Component-Applications-Partnership) at no cost.
What if I see an error in a USCAR/EWCAP document... or have a suggestion to improve?
Contact us at ewcap at uscar.org and we will direct you to the right expert for your topic.
How does USCAR/EWCAP differ from SAE or ISO?
SAE and ISO develop specifications that have a wide range of input from industry experts at many companies. USCAR differs in that they are owned by the Detroit-based vehicle manufacturers (GM, Ford, and FCA US). Therefore, USCAR specifications reflect what those companies specifically are willing to purchase.
What does it mean to have a connector that is "USCAR compliant?"
There are many USCAR specifications. Find out specifically what specification or drawing is compliant and to what level... For example, learning that a connector passed USCAR-2 testing at temperature level 3 (125C), vibration level V4, and water sealing class 2 gives the needed detail to understand what testing has been done.
What is the benefit of USCAR common connector designs?
Connector Design Complexity – Pre-USCAR had a lot of similar but different parts. Tooling and validation costs were high. In the picture below, an example is shown of many designs for a part that has a similar function.
Connector design complexity was reduced with the coordinated effort of the EWCAP group of USCAR. Each red X simulates a part that was eliminated by OEM agreement.

What are other benefits of using USCAR connector designs"
What are the different sub-classifications of connectors (families)?
Families are used to group connectors within a single terminal size. The numbers listed are the 7 USCAR terminal sizes. The number refers to the nominal blade (pin) width for that design. The U or S designation is a sub-category that groups the sealed (S) from the unsealed (U) designs.
How is the USCAR Connector Part Number System Structured?
How do I get the drawing once I have a USCAR Part Number?
Look the part number up on the EWCAP website(http://www.uscar.org/guest/teams/10/Electrical-Wiring-Component-Applications-Partnership ). The "Footprint drawings" are categorized by family. In addition to drawings, we also offer the design electronically in "STEP" format. Downloads are Free! However, the drawing cannot be changed in any way and must be identified as the USCAR drawing. (Make sure you do not copy our drawing onto your format without identifying it as a USCAR drawing... you will not get updates that way.
