Engineering Datasheet: Panel/Screw-Mount Battery Clip, Direct Replacement for Keystone 89
Securing heavy D cylindrical cells on FR4 boards demands massive retention force. Retaining heavy cells requires absolute control of clip spring temper and contact pressure. The Jiatel JT-BC-D-KS89 is a direct footprint replacement for Keystone 89. This clip features a heavy-duty U-channel gripping architecture. It utilizes dual downward solder tails. You can execute seamless board-level power integration. You do not need to alter existing PCB drill hole coordinates.
Verified Board-Level Parameters
| Target Cross-Reference | Direct Footprint Replacement for Keystone 89 |

Target Deployments
- Industrial Equipment: Heavy-duty PCB-mounted power backup modules.
- Security Systems: Large standalone alarm enclosures requiring D cell power.
- Consumer Electronics: High-drain devices needing robust clip stability.
Metallurgical Rigidity & Spring Retention
We stamp the JT-BC-D-KS89 from thick T=0.50mm Spring Steel. This specific formulation guarantees absolute structural rigidity for heavy cells. The 29.87mm high gripping arms prevent cell dislodgement during mechanical shock. The clip will not yield under repeated D cell insertion cycles. We finish the assembly with high-density Nickel Plating. This keeps contact resistance stable and resists corrosion across repeated cell changes.
NPI PCB Footprint Audit & SLA Directive
Board-level integration of heavy clips demands strict adherence to mounting-hole dimensions. Layout errors cause clip misalignment and retention failures. Our engineering rules strictly prohibit the distribution of unverified digital mockups. We execute structural footprint validation exclusively through official [Technical Datasheets]. We rely on dimensionally controlled [2D Footprint Specs].
Confirm that our clip matches your existing mounting pattern. Submit your board constraints directly to our technical desk: NPI Engineering Queue. We will dispatch matched, production-ready PDF drawings within 12 working hours.
