Sensata-Crydom 84140003 SSR Relay SPST-NO 25A 24-280V Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 84140003 is a solid-state relay (SSR) with SPST-NO (1 Form A) x 2 configuration in a hockey puck package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs. The relay is rated for 25A load current with input voltage range of 4-15VDC and load voltage range of 24-280V AC with zero-cross switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 84140003 are qualified based on the following critical electrical and mechanical parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Output type: AC with zero-cross switching
• Input voltage range: 4 ~ 15VDC
• Load voltage range: 24 V ~ 280 V
• Load current rating: 25 A
• Package type: Hockey Puck
• Mounting type: Chassis Mount

Two qualified substitutes meet these core requirements: the Sensata-Crydom 84140000 (active product status with quick-connect termination) and the Sensata Technologies CD2425D1V (active product status with screw terminal termination matching the original).

Parameter Comparison

Engineering Selection Recommendations

The 84140003 is obsolete and no longer in active production. Both substitute parts maintain electrical equivalence across all critical parameters: circuit configuration, voltage ratings, current capacity, and output switching characteristics.

84140000 (Sensata-Crydom): Active product status within the same GN2 series. Maintains identical electrical specifications. Termination differs from the original (quick-connect vs. screw terminal), requiring connector adaptation in existing installations. ROHS3 compliant and REACH affected.

CD2425D1V (Sensata Technologies): Active product status from the Evolution Dual series. Maintains identical electrical specifications and screw terminal termination matching the original part. Direct mechanical and electrical compatibility for replacement applications. RoHS compliant.

Frequently Asked Questions (FAQ)

Q: Can the 84140000 directly replace the 84140003 in existing installations?

A: Electrical functionality is equivalent. However, the 84140000 uses quick-connect termination (0.250" / 6.3mm) while the 84140003 uses screw terminals. Connector adaptation is required for installation.

Q: Is the CD2425D1V a direct drop-in replacement for the 84140003?

A: Yes. The CD2425D1V maintains identical electrical specifications and uses screw terminal termination matching the original part, enabling direct mechanical and electrical compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Circuit configuration (SPST-NO x 2), output type (AC zero-cross), input voltage (4-15VDC), load voltage (24-280V), load current (25A), package type (hockey puck), and mounting type (chassis mount) must remain constant across substitutes.

Q: Are there compliance differences between the substitutes?

A: The 84140000 is ROHS3 compliant and REACH affected. The CD2425D1V is RoHS compliant. Regulatory requirements for your application determine which substitute is appropriate.

Q: Does the hockey puck package remain the same across all three parts?

A: Yes. All three parts use the hockey puck package with chassis mount configuration, ensuring consistent mechanical fit and thermal characteristics.
