DF52-xxP-0.8C

SCONDAR SCT0802H – SignalBee™ Series Crimping Housing

0.8mm Pitch | Compact, Robust, High-Current Wire-to-Board Connector
*Functional Alternative to Hirose DF52-xxP-0.8C Series*

In the pursuit of ever-smaller electronic devices, engineers have long faced a difficult compromise: reduce connector size, and you often sacrifice current capacity, mechanical strength, or assembly reliability. The SCONDAR SCT0802H from the SignalBee™ family eliminates this compromise. This 0.8mm pitch compact board-to-wire crimping housing delivers a rare combination of miniaturization, rugged construction, and high-current performance – serving as a functionally compatible alternative to the Hirose DF52-xxP-0.8C series, built on SCONDAR’s own proprietary tooling and design architecture.

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 SCT0802H is designed for applications where space is at an absolute premium – without compromising on the qualities that matter in real-world manufacturing and field use.

Six Key Features of SignalBee™ SCT0802H

Electrical & Environmental Specifications

Material & Construction – Built for Reliability

• Insulator (Housing): PA4T (Polyamide 4T) – UL94V-0 rated

  • Exceptional heat resistance for reflow soldering processes (compatible with SMT headers)

  • Low moisture absorption – maintains dimensional stability in humid environments

  • High mechanical strength – supports lance retention and resists housing deformation

• Color: Black – standard industry identification

• Halogen-free compliant – meets modern environmental standards

Feature Deep Dive

1. Miniaturized Yet Robust – No Fragility Trade-Off

Unlike many ultra-fine-pitch connectors that become delicate and prone to damage, the SCT0802H incorporates reinforced side walls and strategically placed ribs. The result is a housing that withstands automated assembly handling, cable flexing, and repeated mating cycles without cracking or deforming.

2. BOX-Type Crimp Terminal Compatibility

The SCT0802H is designed to work with BOX-type (enclosed box contact) crimp terminals (SCONDAR SCT0802 series, sold separately). The BOX design:

• Surrounds the mating pin on multiple sides

• Prevents terminal deformation during crimping operations

• Maintains consistent contact normal force

• Provides excellent vibration and shock resistance

3. Partial-Mating Prevention – Assembly Confidence

A common failure mode in fine-pitch connectors is incomplete mating – the housing appears connected but has not fully engaged. The SCT0802H features a positive latch geometry that:

• Produces a distinct tactile click only when fully mated

• Prevents the housing from resting in a partially engaged position

• Allows visual or automated verification of complete connection

4. High Current in a 0.8mm Footprint

Achieving 2.5A (with 28 AWG wire, 2-position configuration) at 0.8mm pitch is a significant engineering achievement. This makes the SCT0802H suitable for power delivery in compact devices – not just signal interconnection.

Functional Compatibility with Hirose DF52 Series

The SCONDAR SCT0802H is engineered to match the key interface dimensions – including 0.8mm pitch, mating envelope, polarizing features, and PCB footprint – of the Hirose DF52-xxP-0.8C series. This allows seamless integration into existing designs originally laid out for DF52 connectors.

However, SCONDAR has developed:

• Proprietary housing and lance geometry (independent tooling)

• Unique terminal interface design and material selection (PA4T vs. specific grades)

• Independent quality and testing protocols

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