1928498057 BDK 2.8 / Terminal Sn / 1.5 - 2.5 mm²

 The Component: Genuine Bosch 1928498057 (1 928 498 057) BDK 2.8 series female receptacle crimp terminal socket contact pin.

Series Taxonomy: Bosch BDK 2.8mm Terminal Series. A premium-grade, heavy-duty damping terminal ecosystem engineered specifically by Robert Bosch GmbH to maintain steady low-to-medium voltage electrical continuity under intense thermal stress and violent powertrain vibration fields.

Terminal Interface: Female flat receptacle socket configuration engineered to establish a tight, multi-point mechanical and electrical surface interface over 2.8mm wide male blade tabs.

Wire Gauge and Plating: Performance-optimized to accept heavy-gauge automotive wiring with a cross-sectional area ranging from 1.50mm2 to 2.50mm2 (equivalent to 14–16 AWG conductors). Stamped from a premium copper alloy substrate finished in a high-grade, corrosion-resistant tin plating.

Locking and Sealing Security: Utilizes a high-retention lance-locking design featuring a robust primary metal locking tang that snaps audibly into the housing cavity to prevent terminal pin back-out under axial tensile pull. Engineered as a sealed-system terminal, working in complete uniformity with a single-wire silicone seal (such as the white 1928300600 seal) to preserve environmental security inside the assembly.

Common Applications: Extensively specified across prominent European passenger car networks, commercial truck platforms (including DAF fleets), and high-performance motorsport wiring harnesses. Most frequently deployed inside high-current and high-exposure engine bay connection plugs, including fuel injector blocks, heavy-duty sensors, ignition coil packs, headlight assemblies, and ABS control modules. Highly vulnerable to terminal throat distortion or loss of contact tension if probed aggressively with non-standard diagnostic test pins.

Bosch 1928498057 BDK 2.8 Series Female Receptacle 1.5 - 2.5mm2 Crimp Terminal Pin

Restore flawless circuit communication, clear persistent diagnostic fault codes, and complete factory-correct wire harness overhauls with the genuine Bosch 1928498057 BDK 2.8 series female crimp terminal contact pin. Precision-manufactured to rigid original equipment Tier-1 automotive engineering standards by Robert Bosch GmbH, this 2.8mm damping receptacle is an industry staple for resolving high-vibration engine bay and chassis harness issues. The contact's smooth insert architecture ensures a seamless glide into the specialized connector cavity block, clicking perfectly past the internal primary retention window to block accidental backing out during heavy vehicle operations.

The 1928498057 terminal contact is stamped from a high-conductivity copper alloy substrate and finished in a highly durable tin plating, mitigating the risks of oxidative tracking and ensuring low electrical contact resistance across extended usage cycles. Engineered specifically to host larger-gauge automotive power and signal lines carrying wire cross-sections from 1.50mm2 to 2.50mm2, it provides a firm, secure crimp root that easily manages continuous current distribution. When paired with a matching individual single-wire silicone seal compressed into the connector housing, it locks out road moisture, engine oil vapor, grime, and debris. This authentic replacement component allows auto-electrical specialists, commercial fleet mechanics, and custom harness builders to deliver zero-resistance, professional factory restorations.
