IDC5 DC Input Module - Equivalent & Substitute Parts

Part Overview

The IDC5 is a DC input module manufactured by Sensata-Crydom, designed to convert 24VDC input signals to 5VDC output at 16mA capacity. This module is classified as Active product status and is ROHS3 compliant. Substitute parts become necessary when the original IDC5 is unavailable, when alternative voltage input ranges are required, or when different packaging configurations are needed for specific application requirements.

Substitute Part Grouping Explanation

Two substitute parts are identified for the IDC5: the 70M-IDC5 and 70-IDC5, both manufactured by Grayhill Inc. These substitutes are qualified based on the following electrical and mechanical parameters:

Common Functional Parameters:

• Output voltage: 5VDC (identical across all parts)
• Output current: 10mA (meets or exceeds minimum requirements)
• Input/output isolation and module type classification
• Color specification: White

Substitution Logic: The 70M-IDC5 and 70-IDC5 accept a wider input voltage range (3–32VDC) compared to the IDC5 (24VDC fixed). This expanded input range allows these parts to function in the IDC5's 24VDC application while providing flexibility for systems with variable supply voltages. Both substitute parts maintain 5VDC output and are packaged as DC input modules with hold-down screw features (70-IDC5) or standard mini configuration (70M-IDC5).

Parameter Comparison

Engineering Selection Recommendations

IDC5 (Sensata-Crydom): Select this part when ROHS3 compliance is mandatory and the application operates exclusively at 24VDC input. This part is Active status with full inventory availability.

70-IDC5 (Grayhill Inc.): This part is the preferred substitute when the application can tolerate RoHS non-compliance and requires a standard form factor with hold-down screw mounting. The wider input voltage range (3–32VDC) accommodates variable supply conditions while maintaining 5VDC output. Active product status with 1010 units in stock.

70M-IDC5 (Grayhill Inc.): Select this part when space constraints require a mini-style form factor and RoHS non-compliance is acceptable. The 3–32VDC input range provides the same voltage flexibility as the 70-IDC5. Active product status with 2100 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 70M-IDC5 or 70-IDC5 directly replace the IDC5 in a 24VDC application?

A: Yes. Both Grayhill substitutes accept 24VDC input within their 3–32VDC operating range and produce 5VDC output, meeting the functional requirements of the IDC5 application.

Q: What is the impact of the lower output current rating on the substitutes?

A: The 70M-IDC5 and 70-IDC5 provide 10mA output current compared to the IDC5's 16mA. Applications requiring more than 10mA output current cannot use these substitutes.

Q: How do packaging differences affect part selection?

A: The IDC5 ships in Tray packaging, while both Grayhill substitutes ship in Bulk packaging. The 70-IDC5 maintains the Standard style with hold-down screw, matching the IDC5 form factor. The 70M-IDC5 uses a Mini style, requiring verification of mechanical fit in the target application.

Q: Are there RoHS compliance implications when substituting?

A: The IDC5 is ROHS3 compliant. Both Grayhill substitutes are RoHS non-compliant. Applications subject to RoHS regulations must retain the IDC5 or identify alternative compliant parts.

Q: What are the timing differences between the main part and substitutes?

A: The IDC5 has 1ms turn-on and turn-off times. Both Grayhill substitutes have faster response times (0.20ms turn-on, 0.40ms turn-off). Applications with strict timing requirements must account for these differences.
