Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 1948255 is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility and quality standards)
• Category: Terminal Blocks (same functional category)
• Number of Positions: 8 positions (maintains circuit connectivity requirements)
• Pitch: 0.200" (5.08mm) (ensures mechanical and electrical compatibility with existing PCB layouts and mating connectors)
• Mounting Type: Through Hole (preserves assembly process compatibility)
• RoHS Compliance: RoHS Compliant (maintains regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (ensures storage and handling compatibility)

The identified substitute part 1954537 meets all primary substitution criteria and represents an active product within the Phoenix Contact COMBICON CC series, providing long-term supply availability and design continuity.
