Key Parameters

Substitute Part Grouping Explanation

Substitution of the RLY70000 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: 3PST-NO (3 Form A)
• Output type: AC, Zero Cross
• Input voltage range: 4 ~ 32VDC
• Load current rating: 25 A
• Mounting type: DIN Rail
• Termination style: Screw Terminal
• Package type: SSR with Integrated Heat Sink
• Series family: RLY7

Allowable Variation:

• Load voltage range may differ provided the substitute operates within the application's specified load voltage requirements

The RLY70100 is identified as the manufacturer-recommended substitute. This part maintains identical input control voltage, circuit topology, current rating, mounting configuration, and termination method. The load voltage range differs (48 V ~ 600 V versus 24 V ~ 660 V), which represents a narrower upper limit but remains suitable for applications operating within the 48–600V window.

Parameter Comparison

Engineering Selection Recommendations

The RLY70100 is the designated manufacturer-recommended substitute for the obsolete RLY70000. Both components share identical electrical specifications for input control voltage (4–32VDC), circuit topology (3PST-NO), output switching characteristics (AC, Zero Cross), and load current capacity (25A). Physical mounting and termination are equivalent, ensuring direct mechanical compatibility in DIN Rail installations.

The RLY70100 carries Active product status, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards. The RLY70100 is RoHS3 Compliant and REACH Unaffected, providing assurance for applications subject to environmental and hazardous substance restrictions.

The load voltage specification difference (48–600V for RLY70100 versus 24–660V for RLY70000) requires verification against the application's actual load voltage requirements. Applications operating loads within the 48–600V range experience full compatibility. Applications requiring operation below 48V or above 600V must be evaluated against alternative component options.

Frequently Asked Questions (FAQ)

Q: Can RLY70100 directly replace RLY70000 in existing installations?
