Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5440774 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions per level: 3
• Pitch: 0.197" (5.00mm)
• Mounting type: Through hole
• Wire gauge compatibility: 14-30 AWG
• Screw thread specification: M3
• Housing material: Polyamide (PA), Nylon

Allowable Variation Parameters:

• Mating orientation: 35° (145°) to 55° (125°) angle variation
• Voltage rating: 250V minimum to 300V maximum
• Wire termination method: Screw or screw with rising cage clamp
• Color: Gray to green
• Series designation: COMBICON BCA to COMBICON SMKDSP
• Product status: Obsolete to active

The substitute part 1733428 maintains all mandatory matching parameters while offering enhanced voltage rating and active product status, making it suitable for direct substitution in applications where the increased mating angle and voltage tolerance are acceptable.

Engineering Selection Recommendations

The Phoenix Contact 1733428 is the designated substitute for the obsolete 5440774 based on the following engineering criteria:

Product Status Alignment: The 1733428 maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 5440774.

Compliance Enhancement: The 1733428 carries ROHS3 compliance with REACH unaffected status, providing superior regulatory alignment for current manufacturing standards.

Electrical Performance: The 1733428 offers increased voltage rating (300V versus 250V), providing additional safety margin in applications operating at or near the original 250V specification.

Mechanical Compatibility: Both parts maintain identical pitch (5.00mm), position count (3), mounting type (through hole), wire gauge range (14-30 AWG), and screw specification (M3), ensuring direct PCB footprint compatibility.

Termination Enhancement: The rising cage clamp termination in the 1733428 provides improved wire retention compared to standard screw termination, while maintaining the same torque specification (0.5-0.6 Nm).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1733428 be used as a direct replacement for the 5440774 on existing PCBs?

A: Yes. Both parts share identical pitch (5.00mm), position count (3), mounting type (through hole), and screw thread specification (M3). PCB footprints are compatible. The mating angle difference (35° versus 55°) affects connector approach angle but does not prevent physical mounting.

Q: What is the significance of the mating orientation difference between these parts?

A: The 5440774 features 35° mating orientation (145° angle with board), while the 1733428 features 55° mating orientation (125° angle with board). This 20° difference affects the approach angle for mating connectors but does not impact electrical performance or PCB mounting compatibility.

Q: Does the voltage rating increase from 250V to 300V affect circuit design?

A: The increased voltage rating in the 1733428 provides additional safety margin and is suitable for all applications rated at or below 250V. No circuit redesign is required for substitution.

Q: What is the difference between screw termination and screw with rising cage clamp?

A: The 1733428 incorporates a rising cage clamp mechanism that provides enhanced wire retention during screw tightening. Both termination methods maintain identical torque specifications (0.5-0.6 Nm) and wire gauge compatibility (14-30 AWG).

Q: Are there any packaging differences between these parts?

A: The 5440774 is supplied in standard packaging, while the 1733428 is supplied in bulk packaging. This affects procurement and handling but does not impact component performance or compatibility.

Q: What compliance certifications should be verified for new designs?

A: The 1733428 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The obsolete 5440774 carries RoHS compliance. For new designs, the 1733428 is the appropriate selection.
