DF3-4S-2C from Hirose Electric Co Ltd is a 4-position rectangular receptacle designed for wire-to-wire or cable interconnect applications where compact size and dependable signal connection are important. As a free-hanging, inline female socket connector with crimp termination and 2.00 mm pitch, it fits well in harness assemblies, compact control units, consumer electronics, industrial equipment, and embedded subsystems that require organized low-profile connections. Engineers typically select this type of connector for its practical balance of density, serviceability, and integration flexibility in single-row cable designs. The supplied status indicates Active, which is favorable for ongoing procurement, although formal lifecycle confirmation should still be checked against current manufacturer documentation. RoHS compliance information is not explicitly provided in the supplied specifications, so compliance status should be treated as information not available pending official datasheet, declaration, or manufacturer confirmation. For regulated designs, buyers should also confirm REACH status and request current compliance documents before release to production.
