Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5440910 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Positions per level: 2
• Pitch: 0.200" (5.08mm)
• Mounting type: Through hole
• Wire gauge range: 14-30 AWG
• Current rating: minimum 15 A
• Voltage rating: minimum 250 V
• Wire termination: Screw-based
• RoHS compliance status

Allowable Variation Parameters:

• Mating orientation angle (35° vs. 55°)
• Voltage rating (250 V vs. 300 V)
• Wire termination method (screw vs. screw with rising cage clamp)
• Series designation (COMBICON BCA vs. COMBICON SMKDSP)

The substitute part Phoenix Contact 1730764 meets all mandatory compatibility requirements while offering enhanced voltage rating and alternative termination mechanism.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1730764 serves as a direct functional substitute for the obsolete 5440910 within the constraints of PCB layout and connector orientation requirements. Both parts maintain identical electrical specifications for current (15 A) and wire gauge accommodation (14-30 AWG), with the substitute offering increased voltage headroom (300 V vs. 250 V). The primary design consideration is the mating angle difference: the 5440910 operates at 35° while the 1730764 operates at 55°. This angular variation requires PCB footprint verification before implementation.

Both parts carry RoHS compliance certification and identical screw torque specifications (0.5-0.6 Nm), ensuring consistent assembly procedures. The 1730764 is currently in active production status with documented inventory availability, whereas the 5440910 is obsolete. The rising cage clamp termination method on the 1730764 provides enhanced wire retention compared to standard screw termination.

Frequently Asked Questions (FAQ)

Q: Can the 1730764 directly replace the 5440910 without PCB modification?

A: Direct replacement depends on PCB layout compatibility. The mating angle differs (35° vs. 55°), requiring verification that the connector orientation aligns with the intended application space and wire routing. Pitch and mounting hole spacing are identical.

Q: Are the electrical ratings compatible for my application?

A: Yes. The 1730764 meets or exceeds all electrical requirements of the 5440910. Both support 15 A current and 14-30 AWG wire gauges. The 1730764 provides additional voltage margin (300 V vs. 250 V).

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

A: Both methods use M3 screw threads with identical torque specifications (0.5-0.6 Nm). The rising cage clamp on the 1730764 provides mechanical wire retention during screw engagement, reducing the risk of wire displacement during assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5440910 and 1730764 are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the inventory status for these parts?

A: The 5440910 (obsolete) has 1035 pieces in stock. The 1730764 (active production) has 845 pieces in stock.
