Pre-Tinned CuNi3Si SUS301 Stamping Terminal for 0.25-0.35mm² Wire
JDE-1187-B composite stamping terminal — CuNi3Si copper strip body with SUS301 steel strip, pre-tinned 2-6 μm.
Product Summary
JDE-1187-B is a composite stamping terminal built from a copper strip CuNi3Si body and a SUS301 steel strip, both pre-tinned to a 2-6 μm thickness. It is specified for 0.25-0.35 mm² automotive wire, with male and female mating insertion and extraction force controlled at 0.5-4 N so the terminal seats smoothly and still retains securely. All manufacturing processes comply with RoHS, and parts ship 5,000 pcs per reel for automated crimping and assembly lines.
Key Features
Bimetal CuNi3Si + SUS301 construction — the copper strip balances strength with conductivity for signal transmission and resists stress relaxation, while the steel strip supplies the spring force that keeps contact reliable after repeated mating cycles.
Pre-tinned 2-6 μm, no oxidation or missing plating — supports solderability and corrosion resistance, and keeps the contact surface consistent between incoming inspection and the crimping station.
Wire range 0.25-0.35 mm² — matches common low-voltage automotive signal harnesses, so one part number covers a defined range of sensor and control circuits.
Mating force 0.5-4 N — insertion stays easy for operators and automated equipment, while retention is high enough to avoid looseness in vibration-loaded harnesses.
Precision stamping quality and RoHS compliance — no deformation, burrs or cracks, unspecified fillets at R0.3, critical dimensions marked * on the drawing, and 5,000 pcs per reel in an outer black plastic bag for line-side handling.

Models and Options
JDE-1187-B is the documented model for this bimetal terminal, released with a drawing in which critical dimensions are marked with an asterisk, with unspecified fillets at R0.3. Beyond this released configuration, the supplier runs in-house tooling, precision stamping and injection moulding, and supports drawing- or sample-based development of plating selection (gold, tin or silver), pin layout, housing shape, wire gauge and harness assembly. Configurations outside the released JDE-1187-B drawing are quoted as project-specific items rather than catalogue variants.
Materials and Structure
The terminal is a two-metal assembly. Copper strip CuNi3Si forms the conductive body: the alloy is chosen for a balance of strength and conductivity and for good stress relaxation resistance, which keeps contact pressure stable in signal circuits. Steel strip SUS301 supplies high elasticity and structural support, holding the contact geometry after repeated mating cycles. Both strips are pre-tinned to 2-6 μm, which improves solderability and corrosion resistance and prevents oxidation or missing plating at the contact zone. Stamping is controlled to a surface free of deformation, burrs and cracks, and the unspecified fillet radius is R0.3.
Applications
JDE-1187-B is intended for low-voltage signal connections in vehicles, where the copper alloy carries the signal and the stainless strip keeps the contact loaded. Typical fits are body electronics, sensor harnesses, ECU and control-unit connections and BMS signal acquisition lines within the 0.25-0.35 mm² wire range. Reel packaging at 5,000 pcs supports automated crimping and assembly of these harnesses.

Customization
Custom plating options — gold, tin or silver — are available to adjust conductivity and corrosion resistance. The supplier also accepts custom pin layout, housing shape, wire gauge and harness assembly built to drawings or samples, and can support sealing and high-current design requirements on other programs. Every request is reviewed against the released JDE-1187-B drawing so that critical dimensions, plating thickness and packaging remain defined before production.
Case Study
Automotive OEM terminal program, Australia — application: automobile terminal connector; volume: 1,000,000 pcs; program duration: 10 years. Precision-stamped terminals with tin plating maintained stable low contact resistance, supporting steady power supply and signal transmission without abnormal temperature rise, signal flicker or intermittent disconnection in low-voltage body electronics, sensor and BMS signal acquisition circuits.
