Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1780480 is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Number of positions: 4
• Pitch: 0.098" (2.50mm)
• Plug wire entry orientation: 180°
• Mounting type: Free Hanging (In-Line)
• Type: Plug with female sockets
• Color: Black
• Contact mating finish: Tin

Allowable Variation Parameters:

• Termination style: IDC substitutes may be replaced with Screwless - Spring Cage, Tension Clamp termination
• Current rating: Substitute may exceed minimum requirement (2A minimum)
• Voltage rating: Substitute may exceed minimum requirement (160V minimum)
• Wire gauge range: Substitute may support broader gauge compatibility (26 AWG minimum)

The substitute part 1778858 maintains all mandatory matching parameters while offering enhanced electrical ratings and termination flexibility, making it a direct functional equivalent for the obsolete 1780480.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778858 is the qualified substitute for the obsolete 1780480 based on the following engineering criteria:

Functional Equivalence: Both components maintain identical mechanical and electrical interface specifications: 4-position configuration, 2.50mm pitch, 180° wire entry, and free-hanging in-line mounting. Physical and electrical compatibility is assured for direct replacement in existing applications.

Compliance Status: The 1778858 is an active product with current ROHS3 compliance certification, whereas the 1780480 is obsolete. Selection of the active substitute ensures continued availability, supply chain stability, and compliance with current regulatory requirements.

Enhanced Electrical Performance: The substitute provides superior electrical ratings (6A at 320V IEC) compared to the original specification (2A at 160V IEC). This enhancement ensures the substitute operates safely within or below the electrical demands of any circuit originally designed for the 1780480.

Termination Compatibility: The transition from IDC to Screwless - Spring Cage, Tension Clamp termination represents a modernization that maintains functional compatibility while offering improved reliability and ease of installation. Both termination methods achieve equivalent electrical and mechanical connection integrity.

Wire Gauge Flexibility: The substitute supports an expanded wire gauge range (20-26 AWG / 0.14-0.5mm²) that encompasses the original specification (26 AWG / 0.14mm²), ensuring compatibility with existing wiring while permitting design flexibility for future applications.

Frequently Asked Questions (FAQ)

Q: Can the 1778858 be used as a direct replacement for the 1780480 in existing assemblies?

A: Yes. The 1778858 maintains identical mechanical dimensions, pitch, wire entry orientation, and mounting configuration. Physical fit and electrical interface compatibility are assured. The enhanced electrical ratings and improved termination method present no compatibility issues for applications originally specified with the 1780480.

Q: What is the primary difference between the IDC termination of the 1780480 and the Screwless - Spring Cage termination of the 1778858?

A: IDC (Insulation Displacement Contact) termination pierces wire insulation during insertion. Screwless - Spring Cage termination uses a tension clamp mechanism that secures stripped wire without piercing. Both methods achieve equivalent electrical connection and mechanical retention. The spring cage design of the 1778858 eliminates the need for wire stripping tools and reduces installation time.

Q: Are there any voltage or current limitations when substituting the 1778858 for the 1780480?

A: No. The 1778858 is rated for 6A at 320V (IEC), which exceeds the original 1780480 specification of 2A at 160V. Any circuit designed for the original part will operate safely with the substitute, as the substitute's ratings encompass and exceed the original requirements.

Q: Does the expanded wire gauge range of the 1778858 (20-26 AWG) affect compatibility with existing 26 AWG wiring?

A: No. The 1778858 fully supports 26 AWG wire, which matches the original 1780480 specification. The expanded range simply permits use of heavier gauge wire (20-24 AWG) if required by future design modifications, without affecting existing installations.

Q: What is the inventory status of these parts?

A: The 1780480 is obsolete with 849 units in stock. The 1778858 is an active product with 2705 units in stock, ensuring reliable long-term availability for new designs and ongoing system support.

Q: Are both parts RoHS compliant?

A: Yes. The 1780480 carries RoHS compliance certification. The 1778858 carries ROHS3 compliance certification, representing the current regulatory standard. Both parts meet environmental and hazardous substance restrictions for industrial applications.
