DC60D40 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The DC60D40 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) relay in a hockey puck form factor. This component is designed for DC switching applications with a 40A load capacity and operates with input control voltages between 4V and 32VDC. The device is currently in active production status with 1,056 units available in inventory. Alternative models may be required due to application-specific voltage requirements, supply chain considerations, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DC60D40 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPST-NO (1 Form A)
• Output Type: DC
• Load Current: 40 A
• Mounting Type: Chassis Mount
• Package / Case: Hockey Puck
• Termination Style: Screw Terminal

Allowable Parameter Variations:

• Input Voltage Range: The substitute must accommodate the 4 ~ 32VDC control input specification
• Load Voltage Range: The substitute load voltage range must encompass or exceed the 1 V ~ 48 V requirement of the main part
• On-State Resistance: Substitute values must not exceed the maximum specified for the application
• RoHS and REACH Compliance: Substitutes must maintain equivalent or superior compliance status

The substitute part 84137870N (Crouzet GND series) meets all mandatory matching criteria and maintains functional equivalence within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The DC60D40 and 84137870N are functionally equivalent for SPST-NO DC switching applications requiring 40A load capacity. Both components maintain active product status and comply with RoHS and REACH regulations. The 84137870N offers an extended load voltage range (5 V ~ 60 V versus 1 V ~ 48 V), which provides additional operational flexibility for applications requiring higher voltage switching. Both devices are classified under identical ECCN and HTSUS codes, indicating equivalent regulatory treatment. Selection between these parts should be based on application-specific load voltage requirements, supply chain availability, and design timeline considerations.

Frequently Asked Questions (FAQ)

Q: Can the 84137870N replace the DC60D40 in all applications? A: The 84137870N is functionally equivalent for applications within the DC60D40 specification envelope. The substitute's extended load voltage range (5 V ~ 60 V) accommodates all DC60D40 load voltage requirements (1 V ~ 48 V). Verify that your specific application does not depend on the lower voltage threshold of 1V, as the 84137870N minimum is 5V.

Q: Are the physical dimensions and mounting identical? A: Both components use hockey puck form factor packaging with chassis mount configuration and screw terminal termination. Physical compatibility is confirmed for direct substitution in existing designs.

Q: What is the difference in on-state resistance between these parts? A: The on-state resistance specification for the 84137870N is not provided in the available technical data. Verify this parameter against your application's thermal and power dissipation requirements before final selection.

Q: Do both parts meet the same compliance standards? A: Both the DC60D40 and 84137870N are RoHS compliant, REACH unaffected, and classified under EAR99 export control. They share identical HTSUS commodity codes (8536.41.0060).

Q: What is the input voltage control range for both relays? A: Both the DC60D40 and 84137870N accept control input voltages between 4VDC and 32VDC, ensuring identical control circuit compatibility.
