PSR-SCP-24DC/MXF2/4X1/2X2/B Equivalent & Substitute Parts

Part Overview

The PSR-SCP-24DC/MXF2/4X1/2X2/B is a DIN rail-mounted relay manufactured by Phoenix Contact, classified as an obsolete product. This 24VDC coil relay features 4PST-NO (4 Form A) contact configuration with 6A contact rating and integrated diode and lighted indicator features. Due to its obsolete product status, identifying functionally compatible substitute components is necessary for system maintenance, redesign, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the PSR-SCP-24DC/MXF2/4X1/2X2/B is based on the following critical parameters:

• Coil Voltage: 24VDC (primary control signal requirement)
• Mounting Type: DIN Rail (form factor and installation compatibility)
• Termination Style: Screw Terminal (connection interface)
• Features: Diode and Lighted Indicator (functional requirements)
• Manufacturer: Phoenix Contact (product line continuity)
• Contact Form and Rating: Electrical switching capability
• RoHS Compliance: Environmental and regulatory compliance

The identified substitute part 1104981 shares the same manufacturer (Phoenix Contact), coil voltage (24VDC), mounting type (DIN Rail), termination style (Screw Terminal), and integrated features (Diode, Lighted Indicator). However, this substitute operates within different contact configuration and current rating parameters, requiring engineering evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1104981 is an active product from Phoenix Contact with current RoHS3 compliance status, providing procurement and supply chain advantages over the obsolete PSR-SCP-24DC/MXF2/4X1/2X2/B. Both components share identical coil voltage (24VDC), mounting configuration (DIN Rail), termination interface (Screw Terminal), and integrated features (Diode, Lighted Indicator).

Critical differences exist in contact configuration and current rating. The main part provides 4PST-NO contact form with 6A rating, while the substitute provides 3PST-NO contact form with 1.6A rating. The substitute operates at reduced coil current (70 mA versus 125 mA) and coil power (1.7W versus 3W), with an expanded operating temperature range (-10°C to 55°C versus -20°C to 45°C).

Selection between these components must be based on specific application requirements regarding contact count, current-switching capacity, and operating temperature boundaries. The substitute's active product status and ROHS3 compliance support long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 1104981 directly replace the PSR-SCP-24DC/MXF2/4X1/2X2/B in all applications?

A: Direct replacement is not universal. The substitute has different contact configuration (3PST-NO versus 4PST-NO) and lower current rating (1.6A versus 6A). Applications requiring four independent switching circuits or currents exceeding 1.6A require alternative solutions.

Q: What are the key compatibility factors for substitution?

A: Coil voltage (24VDC), mounting type (DIN Rail), termination style (Screw Terminal), and feature set (Diode, Lighted Indicator) are compatible. Contact form, current rating, and switching voltage specifications must be evaluated against application requirements.

Q: Does the substitute have better environmental compliance?

A: The substitute carries ROHS3 compliance versus RoHS compliance on the main part. Both have MSL rating of 1 (Unlimited). The substitute supports a wider operating temperature range (-10°C to 55°C versus -20°C to 45°C).

Q: What is the significance of the product status difference?

A: The main part is obsolete, indicating discontinued manufacturing and potential supply constraints. The substitute is active, ensuring current availability, ongoing support, and compliance with current regulatory standards.

Q: Are there packaging differences between these components?

A: The main part uses standard packaging (-), while the substitute is packaged in boxes. Verify packaging requirements for your procurement and storage specifications.
