Engineering Datasheet: THM Coin Cell Retainer, Direct Footprint Replacement for Keystone 3003
Securing Ø20.0mm coin cells in high-vibration environments requires robust through-hole integration. The JIATEL JT-BC-2032-KS3003 is a direct footprint replacement for the Keystone 3003. Unlike the SMT 3002 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 heavy CR2032 and CR2025 backup cells without altering existing PCB drill hole coordinates.
Verified Board-Level Parameters
| Target Cross-Reference | Direct Footprint Replacement for Keystone 3003 |
| Mounting Architecture | Through-Hole Mount (THM) Dual Pin |
| Axial Pin Pitch | 21.11mm Spread (Requires 2-Ø1.85mm Drills) |
| Negative Pad Constraint | 4.00mm Square Minimum (Center Pad) |
| Base Metallurgy | T=0.25mm Phosphor Bronze | Nickel Plated |
Target Deployments
- Industrial Controllers: Heavy-duty PLC modules requiring wave-soldered RTC backup.
- IT Infrastructure: Server motherboards exposed to constant cooling fan vibration.
- Medical Equipment: Stationary diagnostic hardware demanding maximum terminal retention.
Metallurgical Rigidity & Wave Soldering Integrity
We stamp the JT-BC-2032-KS3003 from rigid T=0.25mm Phosphor Bronze. The top clamping arms maintain continuous pressure on the CR2032/CR2025 cells, preventing voltage drop during mechanical impact. We finish the THM tails with high-density Nickel Plating. This maximizes wave solder wettability across the 21.11mm 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.
