SCONDAR SCT12580WRS‑2x – High‑Density Dual Row SMD Right‑Angle Header, Fully Compatible with JST GHD Series (SMxxB‑GHDS‑A‑TF)

Introduction

Flat‑panel TVs, AV equipment, and other consumer electronics require high‑density board mounting in ever‑shrinking enclosures. The 1.25 mm pitch double‑row connector family has become a standard solution, offering compactness with excellent operability despite its small size. The SCONDAR SCT12580WRS‑2x is a dual row surface‑mount (SMD) right‑angle header engineered for such high‑density applications. Fully compatible with the JST GHD series(specifically the SMxxB‑GHDS‑A‑TF SMT right‑angle receptacle headers), it provides a reliable, cost‑effective alternative for wire‑to‑board interconnections requiring secure locking, low insertion force, and automated assembly.

Direct Compatibility with JST SMxxB‑GHDS‑A‑TF Series

The SCT12580WRS‑2x is a form‑fit‑function compatible replacement for the JST SMxxB‑GHDS‑A‑TF dual row SMD right‑angle headers. It shares the same 1.25 mm pitch, identical pin counts (dual row from 2×05 to 2×20 – 10 to 40 contacts), mating interface, and PCB mounting footprint. When paired with standard GHD‑compatible crimp housings (such as SCONDAR SCT12580H‑2x series or JST GHDR‑xxV‑S‑1) and appropriate crimp terminals (e.g., SCONDAR SCT12580T or JST SGHD terminal), the SCT12580WRS‑2x enables seamless integration into existing GHD‑based designs without requalification or PCB layout changes.

Key Specifications

The extended upper temperature rating of +105°C and the LCP housing make this header suitable for reflow soldering and reliable operation in warm environments such as flat‑panel displays and AV equipment.

Space‑Saving Right‑Angle SMD Design

The SCT12580WRS‑2x adopts a right‑angle (horizontal) SMD configuration. Unlike vertical headers that stand upright, the right‑angle orientation allows cables to be routed parallel to the PCB surface, significantly reducing the overall height of the mated connector assembly. This is particularly valuable in slim product designs where vertical clearance is limited, such as flat‑panel TV edge connections, set‑top boxes, and portable AV devices.

The double‑row arrangement maximizes contact density while minimizing board space usage. Compared to a single row 1.25 mm pitch header, the dual row design achieves a significantly higher number of contacts per unit area – a critical advantage in space‑constrained applications.

Robust Mechanical Features Despite Miniature Size

Despite its compact dimensions, the SCT12580WRS‑2x incorporates several key features that ensure reliable operation and excellent user experience:

• Secure lock device – An integral locking mechanism engages with the mating housing’s lock, providing a positive, tactile click when fully mated. This prevents accidental disengagement due to vibration or handling.

• Low insertion force – Optimized pin geometry and housing design reduce the force required to mate with the socket housing, improving assembly efficiency and reducing operator fatigue.

• Prevention of contact deformation – A protective shroud and precise pin alignment prevent stubbing or bending of contacts during mating, especially important in high‑pin‑count connectors.

• Suction area for picking up – The flat top surface of the header provides a reliable area for vacuum pick‑and‑place nozzles, enabling automated SMT assembly.

Material Selection for SMT Reliability

The SCT12580WRS‑2x is built with materials selected for surface‑mount assembly and long‑term reliability:

• Housing: LCP (UL94V‑0) – Liquid Crystal Polymer withstands peak reflow temperatures up to 260°C without deformation, offers low moisture absorption, and provides excellent dimensional stability. The beige color aids automated optical inspection.

• Contacts: Brass with gold plating – Gold‑plated contacts ensure low and stable contact resistance (30 mΩ max), excellent corrosion resistance, and reliable signal integrity, while supporting multiple mating cycles.

• Solder tabs: Brass with tin plating – Tin‑plated solder tabs (retention fittings) provide good solder wetting and strong mechanical retention to the PCB, helping to prevent solder peeling under mechanical stress or thermal cycling.

Designed for Automated Assembly

The SCT12580WRS‑2x is engineered for seamless integration into high‑volume SMT production lines:

• Vacuum pick‑and‑place compatible, thanks to the flat suction area on the header body.

• Supplied in tape‑and‑reel format (standard for SMT components) for use with high‑speed automatic mounters. (Tube packaging may also be available upon request.)

• LCP housing and tin‑plated solder tabs are optimized for lead‑free reflow soldering, ensuring consistent solder joint quality.

Application Areas

Thanks to its low‑profile right‑angle orientation, high density, secure locking, wide temperature range, and automated assembly readiness, the SCT12580WRS‑2x is ideal for:

• Flat‑panel TVs and displays – Edge connections, timing control board interfaces, source driver connections where vertical space is limited

• AV equipment – DVD/Blu‑ray players, home theater systems, soundbars, set‑top boxes

• Computer peripherals – Printers, scanners, monitors (edge‑board connections)

• Industrial controls – Compact PLCs, HMIs, sensor hubs

• Medical equipment – Portable diagnostic devices, patient monitors (non‑critical)

• Automotive infotainment – Navigation units, audio systems (non‑safety critical)
