Sensata Technologies 84140110 SSR Relay - Equivalent & Substitute Parts

Part Overview

The Sensata Technologies 84140110 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 25A load current at 24-280V AC output. This active product features a hockey puck package with quick connect termination and is designed for chassis mount applications. The part is RoHS compliant and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, while maintaining functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 84140631N (Crouzet) is identified based on the following substitution criteria:

Electrical Compatibility Parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2 (identical)
• Output type: AC (identical)
• Input voltage range: 4 ~ 32VDC (encompasses the main part's 17 ~ 32VDC range)
• Load voltage range: 24 V ~ 510 V (encompasses the main part's 24 ~ 280 V range)
• Load current rating: 50 A (exceeds the main part's 25 A requirement)

Mechanical and Compliance Parameters:

• Series: GN2 (identical)
• Product status: Active (identical)
• RoHS compliance: ROHS3 Compliant (meets or exceeds main part requirement)
• Moisture sensitivity: MSL 1 (identical)

The substitute part provides equal or superior electrical performance within the specified parameter ranges, with enhanced current capacity and expanded voltage operating window.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and meet or exceed RoHS compliance requirements. The 84140631N substitute provides superior electrical performance with 50A current capacity versus the 25A rating of the primary part, and extends the load voltage operating range to 510V. Both parts are MSL 1 rated with unlimited moisture sensitivity tolerance.

Selection between these parts should be based on application-specific requirements for current capacity and load voltage range. The substitute part's enhanced specifications do not introduce incompatibility with applications designed for the primary part's parameters.

Frequently Asked Questions (FAQ)

Q: Can the 84140631N substitute for the 84140110 in all applications?

A: The 84140631N meets or exceeds all key electrical parameters of the 84140110. The substitute's 50A current rating and 510V load voltage range encompass the primary part's 25A and 280V specifications. Both parts share identical circuit configuration (SPST-NO x 2), output type (AC), and series designation (GN2).

Q: What are the differences in package and termination?

A: The 84140110 uses quick connect termination (0.250" / 6.3mm) in a hockey puck package. The 84140631N uses screw terminal termination in a module package. These mechanical differences require evaluation for physical installation compatibility in the target application.

Q: Are both parts RoHS compliant?

A: Yes. The 84140110 is RoHS Compliant. The 84140631N is ROHS3 Compliant, which meets current regulatory requirements.

Q: What input voltage ranges do these parts support?

A: The 84140110 operates at 17 ~ 32VDC input. The 84140631N operates at 4 ~ 32VDC input, providing a wider input voltage window that encompasses the primary part's range.

Q: Are both parts currently available?

A: Both parts maintain active product status. Inventory availability should be confirmed through the supplier for current stock levels.
