SCONDAR SCT1252T – Precision Crimp Terminal for 1.25mm Pitch Micro Connectors, Fully Compatible with Hirose DF13‑2630SCF

Введение

In miniature wire‑to‑board and board‑to‑board connections, the reliability of each crimp terminal is critical. The 1.25mm pitch connector family, popularized by the Hirose DF13 series, is widely used in compact consumer electronics, industrial controls, and portable devices. The SCONDAR SCT1252T is a precision‑engineered crimp terminal that serves as a direct, form‑fit‑function replacement for the Hirose DF13‑2630SCF contact. It offers identical mechanical dimensions, comparable electrical performance, and flexible plating options – ensuring seamless integration into existing harness assemblies and automated crimping processes.

Key Features at a Glance

• Direct compatibility with all DF13‑series socket housings (e.g., DF13‑xxDS‑1.25C) and headers

• Miniature design supporting high‑density, low‑profile connections (down to 5.3‑5.8mm mounted height)

• Secure crimp termination for wire sizes 26–30 AWG

• High contact reliability with 1A current rating and 125V voltage rating

• Double‑row capable – enables multi‑contact configurations up to 40 pins

• Available plating options – tin or gold, to suit environmental and cost requirements

Full Compatibility with Hirose DF13 Series

The SCT1252T is mechanically and electrically equivalent to the DF13‑2630SCF. It mates perfectly with DF13‑series receptacle housings (both single‑row and dual‑row types) and headers (SMT or DIP, straight or right‑angle). Engineers can directly substitute SCONDAR terminals in existing DF13‑based cable assemblies without any tooling or housing modification. This provides a reliable second source, reducing supply chain risk and offering competitive pricing.

Electrical and Mechanical Specifications

These ratings make the SCT1252T ideal for signal and low‑power connections in space‑constrained, moderate‑environment applications.

High‑Reliability Crimp Design

The SCT1252T features a precision‑stamped contact with two distinct functional zones:

• Crimp barrel – Designed to securely grip both the conductor (wire core) and insulation. The conductor crimp provides low‑resistance electrical contact, while the insulation crimp offers strain relief, preventing wire pull‑out under vibration or handling.

• Mating interface – A spring‑beam receptacle that ensures stable normal force when mated with a header pin. The design guarantees low contact resistance and maintains performance over multiple insertion/withdrawal cycles.

The terminal’s 0.15mm thick phosphor bronze base provides excellent spring properties and fatigue resistance, while the plating (tin or gold) protects against corrosion and ensures solderability/crimpability.

Optimized for High‑Volume Automatic Crimping

The SCT1252T is supplied in tape‑and‑reel packaging, compatible with standard automatic crimping machines used for DF13‑2630SCF. This allows seamless integration into existing production lines without changing applicators or crimp tooling. The terminal’s consistent strip pitch, carrier alignment, and dimensional accuracy guarantee smooth feeding and high‑yield crimping.

Low‑Profile & High‑Density Applications

Because the SCT1252T is designed for the DF13 connector system, it inherits the system’s key advantages:

• Low mounted height – When assembled into headers, the overall profile can be as low as 5.3mm (DIP straight) or 3.6mm (right‑angle), perfect for slim devices.

• High contact density – Dual‑row housings can accommodate up to 40 contacts, achieving 30% higher density than single‑row 1.25mm pitch connectors.

• Scoop‑proof housing – The box‑style housing prevents mis‑insertion, protecting the terminal from damage.

Plating Options for Different Environments

• Tin‑plated (standard) – Cost‑effective for general indoor applications with mild environmental conditions.

• Gold‑plated (optional) – Recommended for applications requiring superior corrosion resistance, low contact resistance over extended shelf life, or frequent mating cycles (e.g., portable medical devices, industrial sensors).

Both finishes are fully compatible with the mating header pins (tin or gold versions), though gold‑to‑gold mating offers the lowest and most stable contact resistance.

Compatible Applications

The SCT1252T terminal is suitable for a wide range of miniature electronic devices, including:

• Smartphones and tablets (internal battery connections)

• Wearable devices and smartwatches

• Laptop battery packs and LCD assemblies

• Portable medical monitors (e.g., glucometers, pulse oximeters)

• Small home appliances (electronic controls)

• Security systems and IoT sensors

• Drone flight controllers and camera gimbals

Quality Assurance

SCONDAR implements strict quality control measures:

• Dimensional inspection using vision systems and go/no‑go gauges

• Crimp pull‑force testing per EIA/IS‑38 guidelines

• Electrical testing – contact resistance and insulation resistance sampling

• Plating thickness verification (X‑ray fluorescence)

All terminals are RoHS compliant and free from prohibited substances.
