DC200A10 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The DC200A10 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) relay in a hockey puck package. This component is designed for DC load switching applications with a rated load current of 10 A and load voltage range of 1 V to 150 V. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC200A10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be DC to ensure compatibility with DC load switching applications
• Load Current Rating: Must be rated for 10 A minimum
• Load Voltage Range: Must encompass or exceed the 1 V – 150 V operating window
• Package Type: Must be hockey puck to ensure mechanical fit in existing mounting locations
• Mounting Type: Must be chassis mount for installation compatibility
• Termination Style: Must be screw terminal for electrical connection compatibility

The substitute part 84137850N (Crouzet GND series) meets all these criteria, with the exception of input voltage specification, which differs due to the substitute's DC input design versus the original's AC input design. This difference does not affect load-side compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 84137850N (Crouzet GND series) is the qualified substitute for the obsolete DC200A10. Selection is based on the following engineering factors:

• Functional Equivalence: Both relays provide identical SPST-NO switching functionality with matching load current and package specifications
• Mechanical Compatibility: Hockey puck package and chassis mount configuration ensure direct physical replacement
• Electrical Load Compatibility: The 84137850N load voltage range (5 V – 200 V) encompasses the DC200A10 operating range (1 V – 150 V), providing full compatibility for existing DC load circuits
• Product Status: The 84137850N is active and currently available, ensuring supply continuity for replacement applications
• Compliance: Both components carry identical REACH and ECCN classifications, maintaining regulatory compliance in system applications
• Control Circuit Consideration: The input voltage difference (AC versus DC) applies only to the control circuit and does not affect load-side compatibility. System designers must verify that the control signal source can supply 4 – 32 VDC to the 84137850N

Frequently Asked Questions (FAQ)

Q: Can the 84137850N directly replace the DC200A10 in existing installations?

A: Yes, for load-side applications. The 84137850N provides identical SPST-NO switching, 10 A load current rating, hockey puck package, and screw terminal configuration. However, the control input differs: the DC200A10 requires 90 – 140 VAC, while the 84137850N requires 4 – 32 VDC. Verify that your control signal source can supply the appropriate voltage before installation.

Q: What is the significance of the load voltage range difference?

A: The DC200A10 operates with loads from 1 V to 150 V. The 84137850N operates from 5 V to 200 V. The 84137850N range fully encompasses the DC200A10 range, making it compatible for all DC load applications within the original specification. Applications using loads below 5 V require additional evaluation.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The 84137850N carries RoHS Compliant status, which is an additional compliance advantage. Both are classified as MSL 1 (Unlimited moisture sensitivity).

Q: What does "hockey puck" package mean for installation?

A: The hockey puck package is a cylindrical form factor designed for chassis mount applications using screw terminals. Both the DC200A10 and 84137850N use this identical package type, ensuring mechanical fit in existing mounting locations without modification.

Q: Is the 84137850N currently available?

A: Yes. The 84137850N is classified as Active product status with 906 pieces in stock, ensuring availability for replacement applications. The DC200A10 is obsolete and no longer manufactured.
