DC100D20C Equivalent & Substitute Parts

Part Overview

The DC100D20C is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) device in a hockey puck form factor. This component is designed for DC load switching applications requiring 20A capacity with input control voltage ranging from 4 to 32VDC. The part is currently active in production and maintains full RoHS3 compliance. Equivalent and substitute parts are identified when they satisfy the core electrical and mechanical requirements for the intended application, particularly when the original part faces supply constraints or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC100D20C is determined by alignment of the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: DC switching capability
• Input Voltage Range: 4 ~ 32VDC control signal compatibility
• Load Current Rating: 20 A minimum capacity
• Package Form Factor: Hockey puck chassis mount configuration
• Termination Interface: Screw terminal connection
• Compliance Standards: RoHS and REACH regulatory alignment

The substitute part 84137660N (Crouzet GNAD series) satisfies these core substitution criteria. While the load voltage range differs (5 V ~ 100 V versus 1 V ~ 72 V), this represents an extended operational envelope that encompasses the original part's specification and does not restrict substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the DC100D20C and 84137660N are active production components with current regulatory compliance. The DC100D20C maintains RoHS3 certification, while the 84137660N holds RoHS compliance. Both parts are REACH unaffected and share identical electrical control specifications (4 ~ 32VDC input) and load current capacity (20 A).

The primary distinction lies in load voltage operating range. The DC100D20C operates from 1 V to 72 V, while the 84137660N extends this range to 5 V to 100 V. For applications operating within the 5 V to 72 V window, both parts are functionally equivalent. Applications requiring operation below 5 V load voltage are restricted to the DC100D20C.

Selection between these parts should be based on specific load voltage requirements and supply availability. Both maintain identical mechanical interfaces (hockey puck chassis mount with screw terminals) and control signal specifications.

Frequently Asked Questions (FAQ)

Q: Can the 84137660N replace the DC100D20C in all applications?

A: The 84137660N is suitable for applications where the load voltage remains at or above 5VDC. Applications requiring operation below 5VDC load voltage must use the DC100D20C, as the substitute part's minimum load voltage specification is 5V.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both parts utilize the hockey puck form factor with chassis mount configuration and screw terminal termination. Physical compatibility is maintained for direct substitution in existing designs.

Q: What is the significance of the different RoHS compliance levels?

A: The DC100D20C carries RoHS3 certification, while the 84137660N carries RoHS compliance. Both meet current regulatory requirements. RoHS3 represents the most current directive version and may be preferred in applications with strict compliance documentation requirements.

Q: Do the input control voltage specifications differ between these parts?

A: No. Both the DC100D20C and 84137660N accept identical input control voltage of 4 ~ 32VDC, ensuring compatibility with existing control circuitry.

Q: Is the load current capacity the same for both parts?

A: Yes. Both parts are rated for 20A load current, maintaining identical switching capacity for DC loads.

Q: What is the on-state resistance specification for the 84137660N?

A: The on-state resistance specification for the 84137660N is not provided in the available technical parameters.
