PSR-PIP-24DC/MXF1/4X1/2X2/B Equivalent & Substitute Parts

Part Overview

The PSR-PIP-24DC/MXF1/4X1/2X2/B is a 24VDC DIN rail-mounted 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, necessitating identification of functionally compatible alternatives for ongoing system maintenance and new designs requiring equivalent switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PSR-PIP-24DC/MXF1/4X1/2X2/B is determined by the following critical parameters:

• Coil voltage matching (24VDC)
• DIN rail mounting compatibility
• Contact form and switching capability (4PST-NO configuration)
• Contact current rating (6A minimum)
• Maximum switching voltage (250VAC/250VDC)
• Spring terminal termination
• Diode and lighted indicator features
• Operating temperature range compatibility

The identified substitute part 1104972 is a Phoenix Contact relay from the PSR series. However, this substitute exhibits significant parameter deviations that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1104972 shares the same manufacturer (Phoenix Contact), mounting platform (DIN rail), coil voltage (24VDC), and feature set (diode, lighted indicator) as the obsolete PSR-PIP-24DC/MXF1/4X1/2X2/B. Both components maintain RoHS and EAR99 compliance.

However, the substitute exhibits three material deviations:

1. Contact form reduced from 4PST-NO to 3PST-NO, resulting in one fewer switching pole
2. Contact current rating reduced from 6A to 1.6A
3. Maximum switching voltage limited to 24VDC nominal versus 250VAC/250VDC maximum

Selection of part 1104972 is appropriate only for applications where the reduced switching pole count, lower current capacity, and restricted voltage range are compatible with system requirements. Applications requiring the full 4-pole configuration, 6A switching capacity, or higher voltage switching must pursue alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can part 1104972 directly replace the PSR-PIP-24DC/MXF1/4X1/2X2/B in all applications?

A: No. The substitute part has reduced switching poles (3 versus 4), lower current rating (1.6A versus 6A), and limited switching voltage (24VDC nominal versus 250VAC/250VDC maximum). Substitution is valid only when application requirements align with these reduced specifications.

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

A: The PSR-PIP-24DC/MXF1/4X1/2X2/B is classified as obsolete. Part 1104972 is an active product from the same manufacturer's PSR series, providing continued availability for maintenance and new designs.

Q: Are the mounting and termination styles compatible?

A: Yes. Both components use DIN rail mounting and spring terminal termination, ensuring mechanical compatibility in existing installations.

Q: Do both parts meet current compliance requirements?

A: Yes. Both components are RoHS compliant and classified under ECCN EAR99, meeting current regulatory standards.

Q: What is the impact of the reduced coil current specification?

A: Part 1104972 requires 70mA coil current versus 125mA for the original part, resulting in lower power consumption (1.7W versus 3W). This may reduce control circuit loading but does not affect switching performance.
