SCONDAR SCT1501WVS – 1.5 mm Pitch SMD Vertical Header, Compatible with JST ZH Series (BxxB‑ZR‑SM4‑TF)

Введение

The 1.5 mm pitch wire‑to‑board connector family has become a go‑to solution for compact electronic devices where board space is limited and reliability is essential. JST’s ZH series offers a surface‑mount vertical header – the BxxB‑ZR‑SM4‑TF – widely used in portable electronics, sensors, and LED lighting. The SCONDAR SCT1501WVS is a direct form‑fit‑function alternative to this SMT vertical header, delivering the same low profile, fully shrouded design, and stable contact performance. When paired with compatible housings (such as SCONDAR SCT1501H or JST ZHR‑xx) and crimp terminals, it provides a cost‑effective, reliable solution for high‑density wire‑to‑board connections without PCB redesign.

Direct Compatibility with JST BxxB‑ZR‑SM4‑TF Series

The SCT1501WVS is a drop‑in replacement for the JST BxxB‑ZR‑SM4‑TF surface‑mount vertical header. It shares the same 1.5 mm pitch, identical pin counts (available from 2 to 11 positions), PCB mounting footprint, and mating interface. When used with standard ZH‑series housings and terminals, it enables seamless integration into existing designs without requalification or layout changes.

Key Specifications

Low‑Profile and Space‑Saving Design

When mated with a compatible housing, the SCT1501WVS achieves a low mounting height of approximately 5.9 mm from the PCB surface to the top of the header. The depth after mating is about 3.5 mm. These compact dimensions make the SCT1501WVS ideal for applications where vertical clearance is at a premium – such as portable consumer electronics, wearables, and LED modules.

Fully Shrouded Header for Durability and Secure Connection

The SCT1501WVS features a fully shrouded (box‑style) header design. The shroud surrounds and protects the pin terminals, providing:

• Долговечность – Prevents pins from being bent or damaged during handling, shipping, or mating.

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

• Stress reduction – Reinforced housing minimizes stress on SMT solder joints when the connector is subjected to side loads or vibration.

Stable Contact Performance

The SCT1501WVS 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 SCT1501WVS 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 SMT Reliability

The SCT1501WVS is built with materials specifically chosen for surface‑mount assembly:

• Housing: Nylon 9T (PA9T) with UL94V‑0 – PA9T is a high‑temperature thermoplastic designed for reflow soldering. It withstands peak 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 tin plating – Tin‑plated brass provides reliable solderability to the PCB, good conductivity, and corrosion resistance for standard environments.

Designed for Automated Assembly

The SCT1501WVS is engineered for high‑volume SMT production:

• Vacuum pick‑and‑place compatible – The flat top surface of the header provides a stable area for vacuum nozzles.

• Embossed tape packaging – Supplied in tape‑and‑reel format (Package Code 1) for use with automatic mounters. Tube packaging (Code 2) is also available upon request.

• Reflow solder compatible – The PA9T housing is optimized for lead‑free reflow soldering processes, ensuring consistent solder joint quality.

Ordering Information & Pin Counts

The SCT1501WVS is available in pin counts from 2 to 11 positions. The ordering code follows the pattern: SCT1501WVS-xxE1BE (tape & reel) or SCT1501WVS-xxE2BE (tube), where xx = number of pins.

PCB layout dimensions (overall header length, pin placement, etc.) vary with pin count. Please refer to the SCONDAR SCT1501WVS datasheet for exact dimensional drawings.
