Engineering Datasheet: THM Coin Cell Retainer, Direct Footprint Replacement for Keystone 3009
Securing heavy, high-capacity Ø24.0mm coin cells in high-vibration environments requires robust through-hole integration. The JIATEL JT-BC-2450-KS3009 is a direct footprint replacement for the Keystone 3009. Unlike the SMT 3008 variant, this retainer deploys a dual-pin THM architecture. It provides extreme resistance against lateral shear forces. You can execute seamless board-level integration for 5.0mm thick CR2450 backup cells without altering existing PCB drill hole coordinates.
Verified Board-Level Parameters

Target Deployments
- Smart Grid Infrastructure: High-capacity primary power for utility meters and remote data loggers.
- Telematics: Heavy-duty vehicle tracking nodes requiring wave-soldered RTC backup.
- Industrial Automation: Motor control units exposed to constant mechanical shock.
Metallurgical Rigidity & Wave Soldering Integrity
We stamp the JT-BC-2450-KS3009 from rigid T=0.25mm Phosphor Bronze. The top clamping arms maintain continuous pressure on the heavy CR2450 cells, preventing voltage drop during mechanical impact. We finish the THM tails with high-density Nickel Plating. This maximizes wave solder wettability across the 25.40mm pin layout. It eliminates the risk of cold solder joints and physical detachment.
NPI PCB Footprint Audit & SLA Directive
Through-hole integration demands strict adherence to pin pitch dimensions and drill tolerances. Layout errors cause pin bending and wave soldering 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 THM retainer matches your FR4 drill pattern. We must deploy our Senior NPI Engineering Team to ensure a 1:1 footprint replacement. Submit your board constraints directly to our technical desk: NPI Engineering Queue. We will dispatch matched, production-ready PDF drawings within 12 working hours.
