Key Parameters

Substitute Part Grouping Explanation

The 70G-ODC5A from Grayhill Inc. is identified as a manufacturer-recommended substitute for the C4ODCA. Substitution eligibility is determined by the following critical parameters:

• Module Type: Both are DC output modules with identical functional classification
• Output Features: Both include hold-down screw mounting, internal fusing, and status LED indication
• Moisture Sensitivity: Both rated MSL 1 (Unlimited), indicating equivalent environmental tolerance
• Regulatory Compliance: Both carry REACH Unaffected and EAR99 ECCN designations
• Input/Output Voltage Overlap: The 70G-ODC5A output range (4–200VDC) is contained within the C4ODCA range (3–250VDC), supporting applications within the overlapping voltage window
• Output Current Capability: The 70G-ODC5A provides 4.6A output current, exceeding the C4ODCA 1A requirement, ensuring adequate capacity for equivalent load conditions

Parameter Comparison

Engineering Selection Recommendations

The 70G-ODC5A is suitable as a substitute for the C4ODCA based on the following factors:

• Product Status: The 70G-ODC5A maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete C4ODCA
• Regulatory Alignment: Both components share identical REACH and ECCN classifications, supporting equivalent compliance requirements
• Functional Equivalence: Identical feature set (hold-down screw, fusing, status LED) and MSL rating ensure mechanical and environmental compatibility
• Performance Margin: The 70G-ODC5A output current rating (4.6A) provides operational margin above the C4ODCA requirement (1A)
• Voltage Operating Window: Output voltage range overlap (4–200VDC) covers standard DC output applications within the specified band

Selection of the 70G-ODC5A requires verification that the application operates within the 4–200VDC output range and 5VDC input supply specification.

Frequently Asked Questions (FAQ)

Q: Can the 70G-ODC5A directly replace the C4ODCA in all applications?

A: The 70G-ODC5A is suitable for applications where the output voltage requirement falls within 4–200VDC and the input supply is 5VDC. Applications requiring output voltages below 4VDC or above 200VDC, or input voltages outside 5VDC, require additional evaluation.

Q: What is the significance of the higher output current rating on the 70G-ODC5A?

A: The 70G-ODC5A 4.6A output current capability exceeds the C4ODCA 1A specification. This provides operational margin for load current and does not create compatibility issues in applications designed for 1A output.

Q: Are there packaging differences between these modules?

A: The C4ODCA is specified with hold-down screw mounting. The 70G-ODC5A maintains identical mechanical mounting features, supporting direct physical substitution in existing assemblies.

Q: How do the switching times compare?

A: The C4ODCA turn-on time is 0.05 ms versus 0.075 ms for the 70G-ODC5A. The C4ODCA turn-off time is 0.05 ms versus 0.75 ms for the 70G-ODC5A. Applications with strict switching time requirements should confirm compatibility with the 70G-ODC5A timing specifications.

Q: What regulatory certifications apply to both modules?

A: Both the C4ODCA and 70G-ODC5A carry REACH Unaffected status and EAR99 ECCN classification, indicating equivalent regulatory standing for export and environmental compliance purposes.
