Key Compatibility Factors

1. Thread Standards

HYSF connectors use American Unified Thread (UNF) standards, which match Subconn and many Seacon products:

  • MCBH Series: 5/8″-18 UNF-2A (matches Subconn MCBH, Seacon Minilink)
  • Round Small Series: 3/8″-24 UNF-2A (compact alternatives)
  • Ultra Small Series: 5/16″-24 UNF-2A (miniature applications)

2. Pin Configuration

HYSF offers 2-12 pin configurations compatible with major brands:

  • 2-4 pins: Signal/communication (RS232, RS485, Ethernet)
  • 5-8 pins: Power + signal combinations
  • 9-12 pins: Multi-function systems

Real-World Replacement Examples

Example 1: ROV Tether Cable

Original: Seacon 5501-2008 x MINL-16-CCP/L, 5 meters

HYSF Replacement: MCBH Series 4-pin RS232 cable assembly

  • Same thread specification (5/8″-18 UNF)
  • Same pin configuration (4-pin RS232)
  • Same length (5 meters)
  • Cost savings: 42%
  • Delivery: 5 days vs. 6 weeks

Example 2: Subsea Sensor Cable

Original: Subconn CBH4M, 10 meters

HYSF Replacement: Round Small Series 4-pin cable assembly

  • Compatible thread (3/8″-24 UNF vs. Subconn proprietary)
  • Requires housing modification (one-time change)
  • Cost savings: 48% (including modification cost)
  • Long-term savings: 60%+ on replacement orders

Installation Considerations

Direct Replacement (No Modification)

For Subconn MCBH-compatible products:

  • HYSF MCBH Series uses same 5/8″-18 UNF thread
  • Direct bolt-on replacement
  • No housing modification required
  • Ideal for: Emergency replacements, existing inventory

Modification Required

For other brands or optimized designs:

  • May require threaded hole adjustment
  • One-time machining cost
  • Long-term benefits: Lower cost, lighter weight, faster delivery
  • Ideal for: New product development, large fleet upgrades

Quality Assurance

HYSF connectors and cables meet international standards:

  • ISO 9001: Quality management certified
  • IP68: Submersion protection (standard)
  • Depth ratings: Tested to 1000m, 2000m, 3000m, 6000m
  • 100% testing: Continuity, insulation resistance, hi-pot before shipment
