Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1740628 qualifies as a direct substitute for the 5452730 based on the following critical parameters:

Matching Parameters:

• 4-position configuration with 0.197" (5.00mm) pitch spacing
• Female socket plug type with 90° wire entry orientation
• Free-hanging inline mounting configuration
• Screw-based termination method with M3 screw size and identical torque specification (0.5-0.6 Nm)
• Wire gauge compatibility: 0.2-2.5mm² (equivalent to 12-30 AWG range)
• 7mm wire strip length
• 1.024" (26.01mm) insulation height
• Tin contact mating finish
• Retention latches on wire side
• Black color
• Identical ECCN and HTSUS classifications

Operational Differences: The 1740628 operates at 250V (IEC) compared to the 5452730's 320V (IEC), representing a reduced voltage rating. Both maintain 12A current capacity. The 1740628 employs a rising cage clamp termination mechanism within its screw-based system, whereas the 5452730 uses standard screw termination. The 1740628 is classified as active product status with ROHS3 compliance and REACH unaffected designation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1740628 is the designated substitute for the obsolete 5452730 based on functional equivalence across all critical mechanical and electrical parameters. The 1740628 is currently in active production status with ROHS3 compliance certification, providing supply chain continuity for applications previously using the 5452730.

Selection of the 1740628 is appropriate for applications operating at or below 250V (IEC). Applications requiring the full 320V (IEC) rating of the original 5452730 must evaluate whether the reduced voltage specification of the 1740628 meets system requirements. Both components maintain identical current capacity (12A), wire gauge compatibility (0.2-2.5mm²), and mechanical mounting characteristics.

The rising cage clamp termination mechanism in the 1740628 provides enhanced wire retention compared to standard screw termination, offering improved reliability in vibration-prone environments while maintaining the same torque specification and M3 screw interface.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1740628 directly replace the 5452730 in all applications?

A: The 1740628 is mechanically and functionally compatible with the 5452730 across all mounting, wire gauge, and termination torque specifications. However, the voltage rating difference (250V versus 320V IEC) must be evaluated against your system's operating voltage. If your application operates at 250V or below, direct substitution is appropriate.

Q: What is the primary difference between these two parts?

A: The main operational difference is the voltage rating: the 5452730 is rated for 320V (IEC), while the 1740628 is rated for 250V (IEC). Both maintain 12A current capacity and identical mechanical specifications. The 1740628 also incorporates a rising cage clamp termination mechanism for enhanced wire retention.

Q: Are the wire termination torque specifications identical?

A: Yes. Both the 5452730 and 1740628 require M3 screw termination with a torque specification of 0.5-0.6 Nm (4.4-5.3 Lb-In). Installation procedures and torque tools remain consistent between the two parts.

Q: Does the 1740628 support the same wire gauge range?

A: Yes. Both components accept wire gauges from 0.2-2.5mm² (equivalent to 12-30 AWG for the 5452730). Wire strip length is identical at 7mm for both parts.

Q: What is the product status difference, and why does it matter?

A: The 5452730 is classified as obsolete, indicating it is no longer manufactured. The 1740628 is active production status, ensuring ongoing availability and supply chain reliability. For new designs or replacement applications, the 1740628 is the recommended choice.

Q: Are there any compliance or certification differences?

A: The 5452730 carries RoHS Compliant certification. The 1740628 carries ROHS3 Compliant certification with REACH Unaffected designation, representing current regulatory compliance standards. Both components share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.
