Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5450971 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Number of positions: 3
• Pitch: 0.200" (5.08mm)
• Plug wire entry orientation: 90°
• Mounting type: Free Hanging (In-Line)
• Screw size: M3
• Wire gauge range: 12-30 AWG (0.2-2.5mm²)

Electrical Compatibility:

• Current rating (IEC): 12A minimum
• Voltage rating (IEC): 630V minimum
• Current rating (UL): 12A minimum
• Voltage rating (UL): 300V minimum

Material & Safety Compliance:

• Housing material: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0
• Contact mating finish: Tin
• RoHS compliance required

The substitute part must maintain identical mechanical interfaces, electrical performance specifications, and regulatory compliance status to ensure direct interchangeability in existing applications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1792252 is the direct substitute for the obsolete 5450971 terminal block plug. The substitute maintains full mechanical and electrical compatibility across all critical parameters, including pitch, position count, wire entry angle, screw termination, and electrical ratings.

The 1792252 features an enhanced termination mechanism (Rising Cage Clamp) compared to the standard screw termination of the 5450971, providing improved wire retention characteristics while maintaining the same M3 screw interface and torque specification. The UL current rating of the substitute (15A) exceeds the original specification (12A), ensuring adequate performance margin in UL-regulated applications.

Compliance status is enhanced in the substitute: the 1792252 carries ROHS3 Compliant and REACH Unaffected certifications, compared to the RoHS Compliant status of the original part. Both parts maintain UL94 V-0 flammability rating and identical moisture sensitivity classification.

The 1792252 is currently in active production status with substantial inventory availability (2206 pcs), whereas the 5450971 is obsolete. For new designs and ongoing maintenance applications, the 1792252 provides direct functional replacement with improved regulatory compliance and production continuity.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1792252 be used as a direct replacement for 5450971 in existing applications?

A: Yes. The 1792252 maintains identical mechanical interfaces (3 positions, 5.08mm pitch, 90° wire entry, M3 screw, free-hanging mounting) and meets or exceeds all electrical specifications (12A IEC, 630V IEC, 12A UL, 300V UL). The enhanced termination mechanism and higher UL current rating (15A) provide improved performance characteristics.

Q: What is the difference between the screw termination styles?

A: The 5450971 uses standard screw termination. The 1792252 uses Screw - Rising Cage Clamp termination, which provides enhanced wire retention and strain relief while maintaining the same M3 screw interface and 0.5-0.6 Nm torque specification.

Q: Are there packaging differences between these parts?

A: The 5450971 packaging specification is not provided. The 1792252 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The 1792252 carries ROHS3 Compliant and REACH Unaffected certifications, providing enhanced regulatory compliance compared to the RoHS Compliant status of the obsolete 5450971. Both parts maintain UL94 V-0 flammability rating.

Q: What wire gauges are compatible with both parts?

A: Both the 5450971 and 1792252 accept wire gauges of 12-30 AWG (0.2-2.5mm²) with 7mm strip length and M3 screw termination.

Q: Is the 1792252 available in inventory?

A: Yes. The 1792252 is in active production status with 2206 pcs new original in stock, providing reliable supply for replacement and new design applications.
