Substitute Part Grouping Explanation

The DC100D60C qualifies as a direct substitute for the DC100A60C based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: DC
• Load current rating: 60 A
• Load voltage range: 1 V – 72 V
• On-state resistance (max): 6 mOhms
• Package / case: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Moisture sensitivity level: 1 (Unlimited)
• REACH compliance status: REACH Unaffected

Distinguishing Characteristics: The DC100D60C operates with a DC input voltage range of 4 V – 32 VDC, whereas the DC100A60C requires an AC input range of 90 V – 140 VAC. This difference reflects the control signal requirements and does not affect load-side compatibility. The DC100D60C carries an active product status and is RoHS3 compliant, providing superior long-term availability and regulatory alignment compared to the obsolete DC100A60C.

Parameter Comparison

Engineering Selection Recommendations

The DC100D60C is the manufacturer-recommended substitute for the obsolete DC100A60C. Both components maintain identical load-side electrical and mechanical specifications, ensuring functional equivalence in DC switching applications. The primary consideration for component selection is the control signal voltage requirement: the DC100A60C accepts AC input (90 – 140 VAC), while the DC100D60C requires DC input (4 – 32 VDC). System designs must provide the appropriate control signal voltage for the selected component.

The DC100D60C offers superior long-term viability due to its active product status and RoHS3 compliance certification. For new designs and ongoing production support, the DC100D60C is the preferred selection. For legacy system maintenance where AC control signals are already established, the DC100D60C requires control circuit modification to supply DC input voltage within the specified range.

Frequently Asked Questions (FAQ)

Q: Can the DC100D60C directly replace the DC100A60C in existing applications?

A: The DC100D60C provides electrical and mechanical equivalence on the load side (60 A at 1 V – 72 V DC). However, the control signal input differs: DC100A60C requires 90 – 140 VAC, while DC100D60C requires 4 – 32 VDC. Direct physical replacement is possible only if the control circuit can supply the appropriate DC voltage.

Q: Are there any package or mounting differences between these parts?

A: No. Both components use the hockey puck package with chassis mount configuration and screw terminal termination. Physical installation is identical.

Q: What is the significance of the product status difference?

A: The DC100A60C is obsolete, indicating discontinued manufacturing and limited future availability. The DC100D60C is active, ensuring ongoing supply and support. For new designs and long-term system maintenance, the active part is the appropriate choice.

Q: Do both parts meet the same regulatory requirements?

A: Both components are REACH Unaffected and carry EAR99 ECCN classification. The DC100D60C additionally carries RoHS3 compliance certification, providing enhanced regulatory alignment for applications subject to RoHS requirements.

Q: What is the on-state resistance specification, and why is it important?

A: Both parts specify a maximum on-state resistance of 6 mOhms. This parameter determines the voltage drop across the relay during load current conduction and directly affects power dissipation and thermal performance in the application circuit.
