C4IDCG DC Input Module Equivalent & Substitute Parts

Part Overview

The C4IDCG is a DC input module manufactured by Sensata-Crydom, designed to accept 35–60VDC supply voltage and provide isolated 4.5–30VDC output at 25mA. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The module features hold-down screw mounting, status LED indication, and 10ms switching response times for both activation and deactivation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the C4IDCG is determined by compatibility across the following critical parameters:

• Input voltage range acceptance (35–60V nominal)
• Output voltage capability (4.5–30VDC range or fixed output within system tolerance)
• Output current capacity (minimum 25mA)
• Switching response time (10ms turn-on and turn-off)
• Physical mounting interface (hold-down screw compatibility)
• Status indication capability (LED feedback)
• Moisture sensitivity classification (MSL 1)

The 70G-IDC5G from Grayhill Inc. qualifies as a substitute based on overlapping input voltage range (35–60VAC/DC), equivalent switching times, matching physical features, and identical MSL rating. However, the output specification differs: the 70G-IDC5G provides fixed 5VDC output at 10mA, which represents a constrained output profile compared to the C4IDCG's variable 4.5–30VDC range at 25mA. This substitution is valid only where the fixed 5VDC output and reduced 10mA current capacity satisfy system requirements.

Parameter Comparison

Engineering Selection Recommendations

The 70G-IDC5G represents an active product alternative to the obsolete C4IDCG. Both components share identical switching response characteristics, mounting provisions, and environmental compliance ratings. The primary distinction lies in output specification: the 70G-IDC5G delivers fixed 5VDC at 10mA, whereas the C4IDCG provides variable output from 4.5–30VDC at 25mA.

Selection of the 70G-IDC5G is appropriate for applications where the fixed 5VDC output voltage and 10mA current capacity align with system design requirements. The 70G-IDC5G's active product status ensures ongoing availability and manufacturing support, contrasting with the C4IDCG's obsolete classification.

Both components maintain identical REACH and ECCN compliance profiles, supporting equivalent regulatory deployment across jurisdictions.

Frequently Asked Questions (FAQ)

Q: Can the 70G-IDC5G directly replace the C4IDCG in all applications?

A: Direct replacement is valid only where the system design accommodates fixed 5VDC output and 10mA maximum current. Applications requiring variable output voltage (4.5–30VDC range) or current exceeding 10mA require circuit redesign or alternative component selection.

Q: What is the significance of the AC/DC input capability on the 70G-IDC5G?

A: The 70G-IDC5G accepts both AC and DC input across the 35–60V range, providing broader input source compatibility compared to the C4IDCG's DC-only specification. This expanded input flexibility does not affect substitution validity when DC supply is the operational condition.

Q: Are the packaging formats compatible?

A: The C4IDCG packaging specification is not provided in the technical data. The 70G-IDC5G is supplied in bulk packaging. Physical form factor compatibility must be confirmed through mechanical drawing comparison and mounting interface verification.

Q: Do both components share identical switching performance?

A: Yes. Both the C4IDCG and 70G-IDC5G exhibit 10ms turn-on and turn-off response times, ensuring equivalent temporal behavior in control circuit applications.

Q: What compliance considerations apply to both components?

A: Both components are classified as REACH Unaffected and carry EAR99 ECCN designation, supporting equivalent regulatory compliance for export and domestic deployment. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.
