SCONDAR SCT1252H‑2x – A Robust, Cost‑Effective Dual Row Housing Compatible with Hirose DF13‑1.25mm Pitch Socket Series

Introduction

As electronic devices continue to shrink, the demand for high‑density, low‑profile, and reliable interconnection solutions grows. The 1.25mm pitch connector family has become an industry standard for miniature wire‑to‑board and board‑to‑board connections in consumer electronics, industrial equipment, and portable devices. The SCONDAR SCT1252H‑2x Dual Row Housing is engineered to meet these exacting requirements, offering a drop‑in alternative to the widely used Hirose DF13‑xxDS‑1.25C series. With identical mechanical dimensions, comparable electrical ratings, and robust material selection, the SCT1252H‑2x provides design engineers with a reliable second source without requalification or board layout changes.

Direct Compatibility with Hirose DF13‑xxDS‑1.25C Series

The SCT1252H‑2x is a form‑fit‑function replacement for the DF13‑xxDS‑1.25C dual row receptacle housing. It mates seamlessly with all standard 1.25mm pitch headers that comply with the DF13 interface, including both SMT and DIP types. This compatibility allows existing DF13‑based cable assemblies and PCB headers to be used directly with SCONDAR housings, simplifying supply chain diversification and cost reduction.

Space‑Efficient Dual Row Design for Maximum Density

Like its industry counterpart, the SCONDAR SCT1252H‑2x adopts a dual row configuration that achieves up to 40 contacts (20 positions per row, with 2 to 40 pins available). Compared to single row 1.25mm pitch connectors, the dual row design reduces the required board mounting area by approximately 30%, enabling higher circuit density in space‑constrained applications. The housing’s compact dimensions support a low mounted profile – perfectly matching the low‑height requirements of modern portable electronics.

Key Performance Specifications

The SCT1252H‑2x is rated for demanding environments and provides robust electrical performance:

These specifications make the SCT1252H‑2x suitable for signal and low‑power connections in a wide range of applications, from battery packs and sensors to control interfaces and communication modules.

Robust Material and Mechanical Features

The housing is molded from Nylon 66, a thermoplastic known for excellent mechanical strength, heat resistance, and dimensional stability. The material is rated UL94V‑0 for flame retardancy, ensuring safety in critical applications. The natural brown color (custom colors available upon request) provides visual contrast for assembly identification.

Key mechanical design features include:

• Scoop‑proof box structure – The housing’s recessed cavity prevents mis‑insertion of the mating header, protecting terminals and ensuring correct polarization.

• Positive locking mechanism – Integrated latches provide a secure, tactile connection with corresponding headers, preventing accidental disengagement under vibration or shock.

• Crimp contact compatibility – Designed for use with standard 1.25mm pitch crimp terminals (e.g., SCONDAR SCT1251T series, compatible with DF13‑2630SCF or similar), the housing accepts wires from AWG #28 to #32.

Automatic Assembly Ready

The SCT1252H‑2x housing is fully compatible with high‑volume automated assembly processes. It can be supplied in embossed tape‑and‑reel packaging for use with automatic wire crimping and insertion machines, as well as tube packaging for hand assembly. This ensures seamless integration into existing production lines originally set up for DF13 series connectors.

Application Fields

Thanks to its miniature size, high contact density, and reliable performance, the SCONDAR SCT1252H‑2x is ideal for:

• Portable medical devices (glucometers, patient monitors)

• Battery management systems (BMS) for consumer electronics

• Small home appliances (smart speakers, air purifiers)

• Industrial sensors and control panels

• LED lighting modules and signage

• Automotive interior electronics (non‑safety critical)

• Robotics and drones

Why Choose SCONDAR SCT1252H‑2x?

• Form‑fit‑function compatibility with Hirose DF13‑xxDS‑1.25C – no PCB or cable redesign needed.

• Competitive pricing with shorter lead times and flexible MOQ.

• RoHS compliant and committed to conflict‑free material sourcing.

• Strict quality control ensures consistent contact retention and insertion/withdrawal force.

• Global technical support and sample availability.

Conclusion

The SCONDAR SCT1252H‑2x dual row housing offers a dependable, cost‑optimized alternative to the Hirose DF13‑xxDS‑1.25C series. It delivers the same miniature footprint, high contact density (up to 40 pins), robust Nylon 66 construction, and reliable electrical performance required by today’s compact electronic designs. Whether you are looking to secure a second source, reduce bill‑of‑material costs, or simplify logistics, the SCT1252H‑2x is a smart, safe choice.
