Crouzet 85102031 Safety Relay - Equivalent & Substitute Parts

Part Overview

The Crouzet 85102031 is a 3PST safety relay rated for 5A at 24VDC with DIN Rail mounting. This relay is classified as obsolete, making equivalent substitute parts necessary for system maintenance and new installations where the original component is no longer available. The relay features a lighted indicator, screw terminal connections, and operates across a temperature range of -15°C to 55°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Crouzet 85102031 is based on the following critical parameters:

• Coil Voltage: 24VDC (mandatory match)
• Contact Form: 3PST-NO (3 Form A) configuration (mandatory match)
• Mounting Type: DIN Rail (mandatory match)
• Termination Style: Screw Terminal (mandatory match)
• Contact Rating: Minimum 5A (equal or higher acceptable)
• Switching Voltage: 250VAC or higher (equal or higher acceptable)
• Features: Lighted Indicator (maintained)

The Phoenix Contact 2700569 meets all mandatory parameters and exceeds the current rating (6A vs. 5A) and switching voltage specification (250VAC/250VDC vs. 250VAC), making it a valid substitute for the obsolete Crouzet 85102031.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2700569 is the qualified substitute for the obsolete Crouzet 85102031. Both relays share identical coil voltage, contact configuration, mounting type, and termination style. The Phoenix Contact part is currently in active production status, ensuring long-term availability and supply chain continuity.

The Phoenix Contact 2700569 provides enhanced specifications: higher current rating (6A vs. 5A), dual voltage switching capability (250VAC and 250VDC vs. 250VAC only), and extended operating temperature range (-40°C to 55°C vs. -15°C to 55°C). Both parts maintain RoHS compliance and carry the same ECCN and HTSUS classifications.

Timing differences exist between the two relays. The Phoenix Contact part has a longer operate time (250 ms vs. 70 ms) and shorter release time (20 ms vs. 40 ms). These timing characteristics must be evaluated against specific application requirements before final selection.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2700569 directly replace the Crouzet 85102031 in existing installations?

A: Yes, the Phoenix Contact 2700569 is a direct substitute. Both relays feature identical coil voltage (24VDC), contact configuration (3PST-NO), DIN Rail mounting, and screw terminal termination. Physical dimensions and electrical interface compatibility are maintained.

Q: What are the key differences between these two relays?

A: The primary differences are product status (obsolete vs. active), current rating (5A vs. 6A), switching voltage capability (250VAC only vs. 250VAC/250VDC), operating temperature range (-15°C to 55°C vs. -40°C to 55°C), and timing characteristics (operate/release times). The Phoenix Contact part offers higher performance specifications.

Q: Are there timing considerations when substituting the Phoenix Contact 2700569?

A: Yes. The Phoenix Contact relay has a longer operate time (250 ms vs. 70 ms) and shorter release time (20 ms vs. 40 ms). Applications with strict timing requirements must verify that these differences do not impact system performance or safety functions.

Q: Do both relays meet current compliance standards?

A: Both relays are RoHS compliant. The Phoenix Contact 2700569 carries ROHS3 certification and is REACH Affected, indicating compliance with current regulatory requirements. The Crouzet part, being obsolete, may not receive ongoing compliance updates.

Q: What packaging options are available?

A: The Crouzet 85102031 is available in standard packaging. The Phoenix Contact 2700569 is supplied in bulk packaging, which may affect procurement quantities and logistics considerations.
