DF52-xxS-0.8H(21)

SCONDAR SCT0802WRS – SignalBee™ Series SMD Right-Angle Header

0.8mm Pitch | Compact, Robust, High-Current | Functional Alternative to Hirose DF52-xxS-0.8H(21) Series

The modern electronics landscape demands connectors that are simultaneously small, strong, and powerful. The SCONDAR SCT0802WRS from the SignalBee™ family is a 0.8mm pitch SMD right-angle header engineered for board-to-wire applications where space is at a premium but reliability cannot be compromised. Serving as a functionally compatible alternative to the Hirose DF52-xxS-0.8H(21) series, this header integrates seamlessly into existing PCB layouts while incorporating SCONDAR’s own proprietary tooling and contact design.

SignalBee™ – Engineered for the Demands of Miniaturized Electronics

The SignalBee™ series represents SCONDAR’s commitment to pushing the boundaries of fine-pitch connector technology. At 0.8mm pitch, the SCT0802WRS delivers exceptional current handling, mechanical robustness, and assembly reliability – qualities rarely found together in ultra-compact connectors.

Six Key Features of SignalBee™ (SCT0802WRS)

Electrical & Environmental Specifications

Material & Construction – Built for Surface Mount Assembly

Why LCP for Right-Angle SMD Headers?

• Exceptional heat resistance – withstands reflow soldering temperatures without deformation

• Low moisture absorption – maintains dimensional stability; prevents warpage during storage and soldering

• High mechanical strength – supports the stresses of automated board handling and cable insertion

• UL94V-0 flame rating – meets safety requirements for consumer and industrial electronics

Why Tin Plating?

• Cost-effective for high-volume applications

• Solderable – compatible with standard reflow processes

• Adequate corrosion protection for indoor/consumer environments

• Suitable for applications requiring 1A continuous current

Right-Angle SMD Header – Key Design Advantages

BOX-Type Terminal Interface – Reliability by Design

The SCT0802WRS is specifically designed to interface with BOX-type crimp terminals (such as SCONDAR SCT0802TPS164). The header pins are shaped to work with enclosed box contacts to provide:

• Multi-point contact – Multiple spring-action touch points for stable electrical connection

• Consistent normal force – Reliable contact resistance across temperature and vibration cycles

• Protection against deformation – The box contact surround protects the mating interface

• High mating cycle durability – Suitable for applications requiring frequent connection/disconnection

Partial-Mating Prevention – Assembly Confidence

A common failure mode in fine-pitch connectors is incomplete mating – the header and housing appear connected but have not fully engaged. The SCT0802WRS features a positive latch engagement geometry that:

• Produces a distinct tactile click only when fully mated with the wire housing

• Prevents the housing from resting in a partially engaged position

• Allows visual or automated verification of complete connection

• Works in conjunction with the housing’s anti-semi-mating structure

Functional Compatibility with Hirose DF52-xxS-0.8H(21) Series

The SCONDAR SCT0802WRS is engineered to match the key interface dimensions – including 0.8mm pitch, mating envelope, polarizing features, and PCB footprint – of the Hirose DF52-xxS-0.8H(21) series right-angle SMD headers. This allows:

• Seamless integration into existing PCB layouts originally designed for DF52 series headers

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

• Mating compatibility with SCONDAR SCT0802H housing (which offers dimensional compatibility with DF52 series wire housings)

However, SCONDAR has developed:

• Proprietary housing and contact geometry (independent tooling)

• Unique LCP material formulation and molding parameters

• Independent contact forming and plating processes

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