Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC200A40C is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: DC
• Load current rating: 40 A
• Load voltage range: 1 V – 150 V
• On-state resistance: 16 mOhms maximum
• Package type: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal

The DC200D40C qualifies as a manufacturer-recommended substitute. While the input voltage specification differs (4–32VDC versus 90–140VAC), all load-side parameters, mechanical form factor, and electrical performance characteristics remain identical. The DC200D40C represents an active product within the same PowerPlus DC series, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The DC200D40C is the manufacturer-recommended substitute for the obsolete DC200A40C. Both components share identical load-side electrical specifications, mechanical packaging, and thermal performance characteristics. The primary distinction is input voltage: the DC200A40C accepts 90–140VAC input, while the DC200D40C accepts 4–32VDC input. Selection between these parts depends solely on the available control voltage in the target application.

The DC200D40C carries active product status and ROHS3 compliance certification, providing assurance of continued manufacturing support and regulatory alignment with current environmental standards. The DC200A40C, being obsolete, should be replaced with the DC200D40C in new designs or system upgrades where the input voltage specification is compatible.

Frequently Asked Questions (FAQ)

Q: Can the DC200D40C directly replace the DC200A40C in all applications?

A: Direct replacement is possible only if the control circuit provides 4–32VDC input voltage. The DC200A40C requires 90–140VAC input. If your system uses AC input voltage, the DC200D40C is not compatible without control circuit modification.

Q: Are the load-side electrical characteristics identical between these parts?

A: Yes. Both the DC200A40C and DC200D40C deliver 40A load current, support 1V–150V load voltage range, and exhibit 16 mOhms maximum on-state resistance. Load-side performance is equivalent.

Q: Does the hockey puck package remain the same for both parts?

A: Yes. Both components use identical hockey puck form factor with chassis mount configuration and screw terminal connections. Physical and mechanical compatibility is maintained.

Q: Why is the DC200A40C listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The DC200D40C represents the active equivalent within the PowerPlus DC series and should be used for new designs and system replacements.

Q: Is the DC200D40C RoHS compliant?

A: Yes. The DC200D40C carries ROHS3 compliance certification. RoHS status for the DC200A40C is not specified in available documentation.
