Sensata-Crydom 84140901 SSR Relay SPST-NO 40A 24-280V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84140901 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 40A load current at 24V to 280V AC output. This component is classified as Active product status and is RoHS Compliant. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application requirements necessitate different electrical or mechanical specifications within the allowed parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 84140901 are identified based on functional equivalence within the GN2 series solid-state relay category. Substitution is valid when the following criteria are met:

• Circuit configuration remains SPST-NO (1 Form A) x 2
• Output type is AC
• Load voltage range encompasses or exceeds the original specification (24V ~ 280V minimum)
• Load current rating meets or exceeds 40A
• Input voltage range is compatible with control circuit requirements
• RoHS compliance status is maintained or upgraded
• Product status is Active

The substitute part 84140631N (Crouzet manufacturer) meets these criteria with enhanced electrical ratings: 50A load current capacity and extended load voltage range (24V ~ 510V), with expanded input voltage tolerance (4 ~ 32VDC). The primary difference is the termination style (Screw Terminal vs. Quick Connect) and package form factor (Module vs. Hockey Puck), which may require mechanical redesign consideration.

Parameter Comparison

Engineering Selection Recommendations

Both the 84140901 and 84140631N are Active product status components with full RoHS compliance. The 84140631N offers superior electrical specifications with higher load current capacity (50A vs. 40A) and extended load voltage range (24V ~ 510V vs. 24V ~ 280V), making it suitable for applications requiring higher power handling or wider voltage operation.

Selection between these parts depends on mechanical integration requirements. The 84140901 uses Quick Connect termination with Hockey Puck packaging, while the 84140631N uses Screw Terminal with Module packaging. The 84140631N also supports higher input voltage tolerance (4 ~ 32VDC vs. 4 ~ 15VDC), providing greater flexibility in control circuit design.

Both components maintain MSL Level 1 (Unlimited) moisture sensitivity classification and are classified under ECCN EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can the 84140631N directly replace the 84140901 in existing designs?

A: Electrical substitution is valid; however, mechanical redesign is required due to different termination styles (Screw Terminal vs. Quick Connect) and package form factors (Module vs. Hockey Puck). Mounting and wiring configurations must be adapted accordingly.

Q: What is the significance of the higher load current rating (50A vs. 40A) on the substitute part?

A: The 84140631N's 50A rating provides additional current capacity margin. Applications designed for 40A operation remain within safe operating limits on the substitute part, with improved thermal headroom.

Q: Are both parts suitable for the same load voltage applications?

A: The 84140901 operates at 24V ~ 280V load voltage. The 84140631N extends this range to 24V ~ 510V. Applications within the 24V ~ 280V range are compatible with both parts. Applications requiring operation above 280V require the 84140631N.

Q: What is the difference in input voltage tolerance between these parts?

A: The 84140901 accepts 4 ~ 15VDC input control voltage, while the 84140631N accepts 4 ~ 32VDC. The substitute part accommodates a wider range of control circuit designs without additional voltage regulation.

Q: Are both parts RoHS compliant?

A: Yes. The 84140901 is RoHS Compliant, and the 84140631N is ROHS3 Compliant, representing an upgraded compliance standard. Both meet current environmental and hazardous substance restrictions.

Q: What packaging considerations apply to substitution?

A: The 84140901 uses Hockey Puck chassis mount packaging with Quick Connect terminals. The 84140631N uses Module packaging with Screw Terminal connections. Physical mounting location, terminal access, and wiring harness compatibility must be evaluated during design integration.
