Precision 8-Pin Female Housing for Secure Wire-to-Board Integration

The TS30256-08P-21 is specifically designed for applications where electronic modules connect to wiring harnesses—such as engine control units (ECUs), infotainment systems, sensor arrays, and power distribution boards. Its female configuration mates seamlessly with the male TS30256-08P-11 plug, creating a stable, polarized interface that prevents reverse insertion and ensures consistent Electrical Contact. The three-row, 4.0mm pitch layout maximizes space efficiency while maintaining high signal integrity across all eight circuits.

Two-Stage Terminal Retention for Maximum Vibration Resistance

This connector features a two-piece housing system that includes a primary cavity and a secondary locking wedge. After terminals are inserted into the housing, the wedge is slid into place, applying uniform pressure to lock all contacts simultaneously. This secondary retention mechanism is critical in automotive and off-road environments where constant vibration can lead to terminal loosening and intermittent failures. The result is a secure, long-lasting connection that maintains performance under demanding operating conditions.

Advanced Mat Seal Technology for IP-Level Environmental Protection

Each cavity in the TS30256-08P-21 is equipped with a built-in sealing diaphragm within the mat seal. When a terminal is inserted, the diaphragm breaks to form a watertight seal around the conductor. If a terminal is later removed, a dedicated sealing plug must be installed to reseal the cavity and maintain the connector’s moisture and dust resistance. This intelligent sealing system ensures that the entire assembly remains protected—even when not all positions are used—making it ideal for outdoor, marine, and industrial applications.

High-Strength Thermoplastic Construction for Harsh Conditions

Manufactured from either PBT+GF15% or PA66+GF30%, the housing delivers superior mechanical strength, thermal stability, and chemical resistance. These glass-filled materials prevent warping, cracking, or degradation when exposed to engine heat, UV radiation, salt spray, or cleaning solvents. The sleek black finish not only provides a professional appearance but also enhances durability in high-exposure environments such as under-hood installations or marine decks.

Direct Fit for 1-776286-1 Replacement and Custom Harness Builds

The TS30256-08P-21 serves as a cost-effective, high-quality replacement for the TE Connectivity 1-776286-1 connector. It’s widely used in:

• Repairing or upgrading factory-installed ECU and audio harnesses

• Building custom wire-to-board assemblies for aftermarket electronics

• Integrating control modules in yachts, UTVs, and agricultural equipment

• Replacing obsolete connectors in industrial automation systems

• Supplying bulk connectors for OEM production and service centers

Its compatibility with standard crimp tools and widely available terminals makes it a practical solution for both large-scale manufacturing and field repairs.
