SCONDAR SCT1501WV – 1.5 mm Pitch Through‑Hole Vertical Header, Compatible with JST ZH Series (BxxB‑ZR)

Введение

The 1.5 mm pitch wire‑to‑board connector family is a popular choice for compact electronic devices where board space and height are critical. JST’s ZH series, with its low mounting height, fully shrouded header, and housing lance system, has become an industry benchmark. The SCONDAR SCT1501WV is a through‑hole vertical header designed as a direct mechanical and electrical alternative to the JST BxxB‑ZR series. When paired with compatible housings (such as SCONDAR SCT1501H or JST ZHR‑xx) and crimp terminals, it delivers a low‑profile, reliable, and cost‑effective interconnection solution.

Direct Compatibility with JST BxxB‑ZR Series

The SCT1501WV is a form‑fit‑function compatible replacement for the JST BxxB‑ZR vertical header. It shares the same 1.5 mm pitch, identical pin counts (available from 2 to 15 positions or as required), PCB mounting footprint, and mating interface. When used with standard ZH‑series housings and terminals, the SCT1501WV enables seamless integration into existing designs without requalification or PCB layout changes.

Key Specifications

Low‑Profile and Space‑Saving Design

When mated with a compatible housing (e.g., SCT1501H or ZHR‑xx), the SCT1501WV achieves a low mounted height of approximately 5.9 mm from the PCB surface to the top of the housing. The depth after mating is about 3.5 mm. These compact dimensions make the SCT1501WV ideal for applications where vertical clearance is limited, such as portable electronics, LED lighting modules, and small sensors.

Fully Shrouded Header for Durability and Secure Connection

The SCT1501WV features a fully shrouded (box‑style) header design. The shroud surrounds and protects the pin terminals, providing several benefits:

• Долговечность – The shroud prevents the pins from being damaged during handling, shipping, or mating.

• Secure connection – The shroud guides the mating housing into correct alignment, reducing the risk of mis‑insertion.

• Stress reduction – The reinforced housing reduces stress on the solder joints when the connector is subjected to side loads or vibration.

Stable Contact Performance

The SCT1501WV uses round, solid pins with a tin‑plated brass finish. When mated with a housing that provides high contact force (such as the SCT1501H with its lance‑retained terminal), the combination ensures stable, low‑resistance connections. The maximum contact resistance is specified at 20 mΩ, guaranteeing reliable signal integrity in low‑voltage, low‑current circuits.

Compatibility with Housing Lance System

The SCT1501WV is designed to work seamlessly with housings that feature a housing lanceretention system (like the SCONDAR SCT1501H or JST ZHR series). The lance engages with the terminal inside the housing, improving contact insertion workability and providing secure terminal retention. The round pin geometry complements the lance system by allowing smooth insertion and withdrawal while maintaining high normal force.

Material Selection for Reliable Performance

The SCT1501WV is built with high‑quality materials:

• Housing: Nylon 46 (UL94V‑0) – Nylon 46 offers higher heat resistance and mechanical strength compared to standard Nylon 66. It maintains dimensional stability during wave soldering and provides excellent creep resistance in warm environments.

• Contacts: Brass with tin plating – Brass provides good conductivity and mechanical strength. The tin‑plated finish ensures reliable solderability to the PCB and offers good corrosion resistance.

• Color: Beige – The natural beige housing provides visual contrast on the PCB for easy assembly inspection.

Designed for Manual and Automated Assembly

The through‑hole vertical design of the SCT1501WV allows for easy insertion into PCBs, suitable for both hand soldering and wave soldering processes. The header can be supplied in bulk bag packaging (1,000 pcs per bag) for manual assembly, or custom tape‑and‑reel packaging may be available upon request for automated insertion.

Области применения

The SCONDAR SCT1501WV is ideal for applications that originally use the JST BxxB‑ZR series, including:

• Потребительская электроника – Portable audio devices, digital cameras, handheld game consoles

• Small appliances – Coffee makers, air purifiers, smart speakers

• Промышленные средства управления – Sensor interfaces, compact control boards

• Светодиодное освещение – Strip lighting, driver modules, backlighting

• Медицинские изделия – Portable diagnostic equipment (non‑critical)

• Battery management – Small consumer battery packs
