Key Parameters

Substitute Part Grouping Explanation

The PT-IQ-2X2-48DC-PT has one identified substitute part: the Phoenix Contact PT-IQ-2X2+F-48DC-PT (manufacturer part number 2801266). This substitution is valid based on the following matching electrical and mechanical parameters:

• Voltage - Continuous Operating (Max): 37VAC, 53VDC (identical)
• Current - Discharge (Nom) (8/20µS): 10 kA (identical)
• Current - Discharge (Max) (8/20µS): 20 kA (identical)
• Operating Temperature Range: -40°C ~ 70°C (identical)
• Number of Poles: 1 (identical)
• Form Factor: Base + Module (identical)
• Mounting Type: DIN Rail (identical)
• Series: PT (identical)
• RoHS Status: RoHS Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The substitute part differs in product status (Active vs. Obsolete) and includes additional regulatory approvals (cCSAus, CSA, UL). The protection level voltage differs (1.3 kV vs. 800 V), representing an enhanced specification in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The PT-IQ-2X2+F-48DC-PT (2801266) is the direct substitute for the obsolete PT-IQ-2X2-48DC-PT (2801265). The substitute part maintains all critical electrical parameters including continuous operating voltage, discharge current ratings, and operating temperature range. The substitute part carries Active product status and includes additional regulatory certifications (cCSAus, CSA, UL), providing enhanced compliance documentation for applications requiring third-party approvals. The increased protection level voltage (1.3 kV vs. 800 V) in the substitute part represents an improved specification that does not compromise backward compatibility in applications designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can the PT-IQ-2X2+F-48DC-PT directly replace the PT-IQ-2X2-48DC-PT in existing installations?

A: Yes. Both parts share identical electrical ratings for continuous operating voltage (37VAC, 53VDC), discharge current (10 kA nominal, 20 kA maximum), operating temperature range (-40°C to 70°C), and mechanical form factor (DIN rail-mounted, single-pole, Base + Module configuration). The substitute part's higher protection level voltage (1.3 kV) does not create compatibility issues in applications designed for the original 800 V specification.

Q: What is the significance of the "+F" designation in the substitute part number?

A: The "+F" designation indicates a design variant within the PT series. The specific functional or feature differences associated with this designation are not detailed in the provided specifications. Consult Phoenix Contact technical documentation for detailed variant information.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, design lifecycle, and production decisions. The availability of the active substitute part (2801266) ensures continued access to equivalent protection functionality.

Q: Are there packaging differences between these parts?

A: The original part (2801265) packaging is not specified in the provided data. The substitute part (2801266) is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What regulatory approvals apply to each part?

A: The original part (2801265) has no specified approval agencies listed. The substitute part (2801266) carries approvals from cCSAus, CSA, and UL. If your application requires specific regulatory certifications, the substitute part's additional approvals may provide compliance advantages.
