Equivalent & Substitute Parts for D2450T

Part Overview

The D2450T is a Solid State Relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) in a Hockey Puck package. This component is designed for AC load switching applications with zero-cross detection, operating with a 24V to 140V load voltage range and a maximum load current of 50A. The part is currently Active in product status and RoHS Compliant.

Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or application-specific requirements while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D2450T is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with Zero Cross detection for compatible load switching behavior
• Load Current Rating: Must be rated for 50A to ensure adequate current handling capacity
• Input Voltage Range: Must accommodate 3 ~ 32VDC control signal input
• Load Voltage Range: Must support operation within or exceed the 24V ~ 140V range
• Package / Case: Must be Hockey Puck form factor for mechanical compatibility
• Termination Style: Must use Screw Terminal for connection compatibility
• Mounting Type: Must be Chassis Mount for installation compatibility

The substitute part 84137460N (Crouzet, GNA Series) meets all critical substitution criteria. While the load voltage range extends to 660V (exceeding the D2450T specification), this represents an expanded capability that does not compromise compatibility with the original 24V ~ 140V operating range.

Parameter Comparison

Engineering Selection Recommendations

Both the D2450T and 84137460N are Active products with RoHS Compliance certification, ensuring regulatory alignment and ongoing manufacturer support. The D2450T remains the primary selection for applications operating within the 24V ~ 140V load voltage specification. The 84137460N (Crouzet GNA Series) is a qualified substitute when the D2450T is unavailable, provided the application load voltage does not exceed 660V. The extended load voltage range of the 84137460N does not introduce incompatibility with lower voltage applications within the 24V ~ 140V band.

Frequently Asked Questions (FAQ)

Q: Can the 84137460N be used as a direct replacement for the D2450T?

A: Yes, the 84137460N meets all critical substitution parameters: identical circuit configuration (SPST-NO), matching output type (AC, Zero Cross), equivalent load current rating (50A), compatible input voltage range (4 ~ 32VDC), and identical package form factor (Hockey Puck). The extended load voltage range (48V ~ 660V) does not prevent operation within the original 24V ~ 140V specification.

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

A: The D2450T operates with input voltage from 3VDC, while the 84137460N operates from 4VDC. For applications requiring control signals below 4VDC, the D2450T is the required selection. For applications operating at 4VDC and above, both parts are compatible.

Q: Are there any mechanical compatibility concerns when substituting?

A: No. Both parts use identical Hockey Puck packaging, Chassis Mount configuration, and Screw Terminal termination. Physical installation and electrical connection methods are identical.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the D2450T and 84137460N are RoHS Compliant and maintain Active product status, ensuring compliance with current environmental and regulatory requirements.
