Substitute Part Grouping Explanation

Substitution of the PSR-PIP-24DC/MXF4/4X1/2X2/B is constrained by the following critical parameters:

• Coil Voltage: 24VDC operation is mandatory for direct circuit compatibility
• Mounting Type: DIN Rail mounting is required for panel integration
• Contact Form & Rating: The 4PST-NO configuration with 6A switching capacity defines the electrical load capacity
• Switching Voltage: Maximum 250VAC/250VDC capability establishes the voltage isolation class
• Termination Style: Spring Terminal connection is specified for this application
• Manufacturer Continuity: Phoenix Contact PSR series maintains design and performance consistency

The identified substitute part (1104972) is from the same Phoenix Contact PSR series and shares the same coil voltage, mounting type, termination style, and manufacturer lineage. However, this substitute exhibits reduced contact capacity (1.6A vs. 6A) and different contact form (3PST-NO vs. 4PST-NO), indicating it is suitable only for applications with lower current requirements and fewer switching poles.

Parameter Comparison

Engineering Selection Recommendations

The PSR-PIP-24DC/MXF4/4X1/2X2/B is obsolete and no longer in active production. The identified substitute, part number 1104972, is an active Phoenix Contact PSR series component with identical coil voltage, mounting type, and termination style.

Substitution is valid only when:

• Application current requirements do not exceed 1.6A per contact
• System design can accommodate reduction from 4 switching poles to 3 switching poles
• Operating voltage is limited to 24VDC nominal (vs. the original 250VAC/250VDC capability)

Compliance Status:

Both components maintain RoHS compliance. The substitute (1104972) carries ROHS3 certification, representing current regulatory alignment. Both components are rated MSL 1 (Unlimited moisture sensitivity), ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1104972 directly replace the PSR-PIP-24DC/MXF4/4X1/2X2/B in all applications?

A: No. The substitute has lower current capacity (1.6A vs. 6A) and fewer switching poles (3 vs. 4). Substitution is valid only when the application current does not exceed 1.6A per contact and the system requires no more than 3 switching poles.

Q: What is the primary difference in switching capability?

A: The original part supports 250VAC and 250VDC maximum switching voltage with 6A contact rating. The substitute is rated for 24VDC nominal operation with 1.6A contact rating, representing a significant reduction in both voltage isolation and current capacity.

Q: Are the mounting and termination styles identical?

A: Yes. Both components use DIN Rail mounting and Spring Terminal termination, ensuring mechanical and electrical interface compatibility at the panel level.

Q: Does the substitute have the same coil power consumption?

A: No. The substitute draws 1.7W (70mA at 24VDC) compared to the original 3W (125mA at 24VDC), resulting in lower power consumption and reduced thermal load on the control circuit.

Q: Are there any temperature range differences?

A: Yes. The original operates from -20°C to 45°C, while the substitute operates from -10°C to 55°C. The substitute has a narrower low-temperature range but extends the upper operating limit by 10°C.

Q: What is the inventory status for each part?

A: The original PSR-PIP-24DC/MXF4/4X1/2X2/B has 1049 pieces in stock (obsolete status). The substitute 1104972 has 694 pieces in stock (active status).
