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

Part Overview

The PSR-PIP-24DC/MXF2/4X1/2X2/B is a 24VDC relay manufactured by Phoenix Contact, configured as a 4PST-NO (4 Form A) switching device with 6A contact rating. This component is classified as obsolete, indicating that direct replacement with current production equivalents may be necessary for new designs or system maintenance. The part features a diode and lighted indicator, operates on spring terminals, and is mounted on DIN rail systems. Due to its obsolete status, identifying functionally compatible alternatives is essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PSR-PIP-24DC/MXF2/4X1/2X2/B is determined by the following critical parameters:

• Coil voltage matching (24VDC)
• DIN rail mounting compatibility
• Spring terminal termination style
• Diode and lighted indicator features
• RoHS and regulatory compliance (EAR99 classification)

The identified substitute part, Phoenix Contact 1104972, shares the same manufacturer, coil voltage, mounting type, termination style, and feature set. However, this substitute operates as a configurable safety module with reduced contact form (3PST-NO versus 4PST-NO) and lower current rating (1.6A versus 6A). This substitution is valid only for applications where the lower contact configuration and current capacity are acceptable within the system design.

Parameter Comparison

Engineering Selection Recommendations

The PSR-PIP-24DC/MXF2/4X1/2X2/B is obsolete and no longer in active production. The Phoenix Contact 1104972 is the manufacturer-recommended substitute and maintains active product status, ensuring long-term availability and supply chain continuity.

Both parts comply with RoHS regulations and carry EAR99 export classification. The substitute part (1104972) offers enhanced RoHS3 compliance and operates across a wider temperature range (-10°C to 55°C versus -20°C to 45°C).

Selection between these parts depends on application requirements:

• If the application requires four independent switching circuits at 6A capacity, the original part specification must be maintained or an alternative 4PST-NO relay must be sourced.
• If the application can operate with three switching circuits at 1.6A capacity, the 1104972 substitute is suitable and provides the advantage of active product status and improved compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the 1104972 directly replace the PSR-PIP-24DC/MXF2/4X1/2X2/B in all applications?

A: No. The substitute has reduced contact form (3PST-NO versus 4PST-NO) and lower current rating (1.6A versus 6A). Substitution is valid only if the application requirements align with these reduced specifications.

Q: What is the primary reason for seeking a substitute?

A: The original part is obsolete. The 1104972 is the manufacturer-recommended alternative with active production status.

Q: Are the coil voltage and mounting specifications identical?

A: Yes. Both parts operate on 24VDC and mount on DIN rail systems with spring terminal connections, ensuring mechanical and electrical interface compatibility at the coil and mounting level.

Q: How do the switching voltage ratings differ?

A: The original part switches up to 250VAC or 250VDC maximum. The substitute is rated for 24VDC nominal switching voltage, limiting its use to low-voltage DC applications.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant. The substitute meets the more recent ROHS3 Compliant standard, indicating improved environmental compliance.

Q: What is the packaging difference?

A: The original part is supplied with standard packaging. The substitute is supplied in a box. Verify packaging requirements for your procurement and storage procedures.
