Verified Engineering & Form Factor
Hardware design teams require absolute certainty when sourcing replacement components for existing molded enclosures. The JIATEL JT-BC-KS209 is rigorously validated as a direct footprint alternative to the Keystone 209. By precisely matching the 7.92 mm chassis width and the 11.82 mm vertical profile, this leaf spring contact guarantees seamless, tool-less insertion into your current AA battery compartments without prompting costly tooling modifications.
Target Cross-Reference Parameters
- ✔Replacement Status: 1:1 Match for Keystone 209
- ✔Cell Configuration: Standard AA Cylinder
- ✔Chassis Grip: 2-1.30 mm lateral retaining slots
- ✔Lower Angle Tab: 1.52 mm width support
9-Point Array & Fatigue Resistance
A critical feature of this battery contact is the 9-point stamped dimple array on the mating face. This geometry focuses the compression force to penetrate microscopic oxidation layers on the battery terminal, ensuring a low-resistance connection while actively absorbing longitudinal cell tolerances. To prevent structural yielding, the entire component is stamped from T=0.30 mm Spring Steel, delivering exceptional fatigue extremes and reliable tension recovery across thousands of battery replacement cycles.
Metallurgical Profile
The spring steel core is fully encased in a high-density Nickel Plating. This dual-layer approach provides the mechanical rigidity necessary for chassis retention while sealing the base metal against aggressive environmental corrosion and galvanic degradation.
NPI Compliance & Tolerance Warning
Mismatching slide-in contacts with unverified chassis ribs leads to terminal dislodgment. We strictly limit the distribution of 3D CAD mockups to prevent assembly failures.
