SMxxB-SRSS-TB

SCONDAR SCT1001WRS – SignalBee™ Series SMD Right-Angle Header

1.0mm Pitch | Compact, Low-Profile, High-Reliability | Functional Alternative to JST SH SMxxB-SRSS-TB Series

The 1.0mm pitch crimp-style connector has long been the gold standard for compact wire-to-board connections in portable electronics. The SCONDAR SCT1001WRS is a 1.0mm pitch SMD right-angle header designed to complete the wire-to-board connection system with a low-profile, edge-mounted orientation. Serving as a functionally compatible alternative to the JST SH SMxxB-SRSS-TB series, this header delivers the same core engineering principles – compact low-profile design, high-pressure contact interface, and assured connection reliability – while incorporating SCONDAR’s own proprietary tooling, material formulation, and contact geometry.

The SH Legacy – Refined for Edge-Mount Applications

The original SH series earned its place as the world’s first 1.0mm pitch crimp-style connector by delivering:

• Compact, low-profile design – Enabling dense PCB layouts in portable electronics

• Housing lance engagement – Excellent performance with small-diameter wires

• High-pressure contact design – Superior contact reliability and assured connection

The SCONDAR SCT1001WRS carries forward these engineering principles in a right-angle SMD package – ideal for edge-board connections, cable exits parallel to the PCB, and space-constrained enclosures.

Right-Angle SMD Header – Key Design Features

High-Pressure Contact Interface – Assured Connection

When mated with a wire-side housing containing crimped terminals (such as SCONDAR SCT1001T), the SCT1001WRS header pins engage with the high-pressure contact design of the mating terminal:

This high-pressure interface is particularly important for small-diameter wires and low-voltage applications where contact resistance must remain consistently low.

Right-Angle vs. Vertical – Choosing the Right Orientation

Solder Reflow Compatibility

The SCT1001WRS is designed for standard surface mount assembly processes:

Functional Compatibility with JST SH SMxxB-SRSS-TB Series

The SCONDAR SCT1001WRS is engineered to match the key interface dimensions – including 1.0mm pitch, mating envelope, polarizing features, and PCB footprint – of the JST SH SMxxB-SRSS-TB series. This allows:

• Seamless integration into existing PCB layouts originally designed for SH series right-angle headers

• Mating compatibility with SCONDAR SCT1001H / SCT1001HA housings (which offer dimensional compatibility with JST SHR series housings)

• Direct footprint compatibility – no PCB redesign required for most applications

However, SCONDAR has developed:

• Proprietary housing and contact geometry (independent tooling)

• Unique PA9T material formulation

• Independent contact forming and plating processes

• Independent dimensional and performance specifications

This ensures functional compatibility without patent or design infringement. Engineers should always perform application-specific validation.
