HSMT Spring Contact: 1:1 Replacement for 0987 Layouts
Low-profile, parallel board-to-board architectures require interconnects that lie flat against the PCB. The Jiatel 0987-compatible series delivers a precise Horizontal Surface Mount (HSMT) solution, engineered as a direct drop-in replacement for legacy 0987 footprints. Featuring a substantial 0.391″ (9.931mm) initial length and a deep 0.118″ (2.997mm) working stroke, this side-actuated plunger absorbs significant mechanical tolerances in edge-mating scenarios. To ensure zero-defect conductivity under severe mechanical shock (50G) and high-frequency vibration, the brass alloy shell is heavily plated with 20μ” gold over a nickel barrier.

NPI Validation & Footprint Coplanarity
Horizontal mounting structures are highly susceptible to reflow floating if the barrel geometry is not perfectly machined. We mitigate SMT assembly risks by enforcing strict coplanarity audits at the manufacturing level. Our engineering methodology relies entirely on extracting precise parameters from official [Technical Datasheets] and validating against [2D Footprint Specs], bypassing the inherent inaccuracies of generic digital models.
To confirm that our HSMT barrel dimensions and resting flats align perfectly with your existing PCB pads, engage our Senior NPI Engineering Team. We execute a strict 12-hour fast response SLA for all technical drawing requests and footprint cross-references. Route your layout parameters here: NPI Engineering Queue
Disclaimer: While our HSMT spring pins perfectly mirror the required mounting geometry and resting flats of legacy 0987 components, specific parameters such as internal force dynamics and specialized plating thicknesses can be customized per project requirements, diverging from original OEM standard defaults.
