SCONDAR SCT12580H‑2x – High‑Density Dual Row Housing, Fully Compatible with JST GHD Series (GHDR‑xxV‑S‑1)

Introduction

Modern flat‑panel TVs, AV equipment, and other consumer electronics demand increasingly high‑density board mounting while maintaining excellent operability and reliability. The 1.25mm pitch double‑row connector family has become a key solution for such applications, offering a compact footprint with secure locking and low insertion force. The SCONDAR SCT12580H‑2x is a dual row crimp housing designed to meet these exact needs. Fully compatible with the JST GHD series (specifically the GHDR‑xxV‑S‑1 receptacle housings), it provides a reliable, cost‑effective alternative for high‑density wire‑to‑board interconnections.

Direct Compatibility with JST GHDR‑xxV‑S‑1 Series

The SCT12580H‑2x is a form‑fit‑function compatible replacement for the JST GHDR‑xxV‑S‑1 dual row housings. It shares the same 1.25mm pitch, identical pin counts (10 to 40 contacts – 2×5 through 2×20), compatible mating interface, and PCB mounting footprint. When paired with standard 1.25mm pitch headers (such as SCONDAR SMT or through‑hole types) and appropriate crimp terminals (e.g., SCONDAR SCT1252T series, compatible with JST GHD terminals), the SCT12580H‑2x enables seamless integration into existing GHD‑based designs without requalification or tooling changes.

Key Specifications

All electrical and environmental ratings below are taken directly from the provided product specification:

The extended upper temperature rating of +105°C makes this housing suitable for applications with higher ambient heat, such as AV equipment and flat‑panel displays.

Designed for High‑Density Board Mounting

The SCT12580H‑2x adopts a double‑row configuration that maximizes contact density while minimizing board space usage. Compared to a single row 1.25mm pitch connector, the dual row design achieves approximately 30% higher mounting density on the PCB – a critical advantage in space‑constrained products like flat‑panel TVs, set‑top boxes, and portable AV devices.

The following dimensions (A and B) correspond to the overall housing length and width for each pin count. Exact PCB layout dimensions are available in the SCONDAR datasheet.

Robust Mechanical Features for Demanding Applications

Despite its miniature size, the SCT12580H‑2x incorporates several key features that ensure reliable operation and excellent user experience:

• Secure lock device – An integral locking mechanism provides a positive, tactile click when mated with a compatible header. This prevents accidental disengagement due to vibration or handling, ensuring a stable connection in portable and fixed equipment.

• Low insertion force – The housing geometry is optimized to reduce the force required to insert the crimp terminals and to mate with the header. This improves assembly efficiency and reduces operator fatigue in manual assembly lines.

• Prevention of contact deformation – The housing features a protective shroud and internal contact alignment ribs that prevent stubbing or bending of the mating header pins during blind mating. This is especially important in high‑pin‑count connectors where misalignment can cause damage.

• Suction area for pick‑up – The top surface of the housing is designed with a flat, unobstructed area compatible with vacuum pick‑and‑place nozzles. This allows the housing to be automatically picked and placed onto the PCB or into assemblies (when combined with headers that support SMT placement), facilitating high‑volume automated production.

Material Selection for Reliability and Safety

The SCT12580H‑2x housing is molded from PA66 (Nylon 66) , a widely used engineering thermoplastic known for its excellent mechanical strength, heat resistance, and chemical stability. The material is rated UL94V‑0 for flame retardancy, ensuring compliance with safety standards for electronic equipment. The white color provides high contrast for easy visual inspection and automated optical inspection (AOI) systems.

Application Areas

Thanks to its high density, secure locking, and wide operating temperature range, the SCONDAR SCT12580H‑2x is ideal for:

• Flat‑panel TVs and displays – Internal signal and power distribution between main boards, timing control boards, and source driver boards

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

• Computer peripherals – Printers, scanners, monitors

• Industrial controls – Compact PLCs, human‑machine interfaces, sensor hubs

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

• Automotive – Infotainment systems, navigation units (non‑safety critical)
