IDC5N DC Input Module - Equivalent & Substitute Parts

Part Overview

The IDC5N is a DC input module manufactured by Sensata-Crydom, designed to convert a 10–48VDC supply into a regulated 5VDC output with 16mA capacity. This module features a hold-down screw for secure mounting and operates with 34mA input current, 8ms turn-on time, and 7ms turn-off time. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IDC5N is determined by the following critical parameters:

• Output voltage specification (5VDC)
• Output current capacity (16mA minimum)
• Input voltage range compatibility
• Physical form factor and mounting features (hold-down screw)
• Switching response times (turn-on and turn-off)

Two substitute parts are identified based on these criteria:

IDC5F (Sensata-Crydom): Operates within a narrower input voltage range (4–32VDC) but maintains identical output specifications (5VDC, 16mA). This part is active and RoHS compliant, offering improved switching performance (0.05ms turn-on, 0.10ms turn-off).

70-IDC5NP (Grayhill Inc.): Provides dual AC/DC input capability (15–32VAC or 10–32VDC) with 5VDC output. Output current is reduced to 10mA, and switching times are 5ms for both turn-on and turn-off. This part is active but RoHS non-compliant.

Engineering Selection Recommendations

IDC5F Selection Criteria:

The IDC5F is suitable for applications where the input voltage range does not exceed 32VDC. This part maintains full output current capacity (16mA) and offers significantly faster switching response. As an active product with RoHS compliance, it is the preferred choice for new designs and systems requiring regulatory adherence. The higher input current specification (68mA vs. 34mA) reflects improved efficiency in the narrower voltage range.

70-IDC5NP Selection Criteria:

The 70-IDC5NP provides flexibility for systems requiring AC input capability in addition to DC operation. However, the reduced output current (10mA vs. 16mA) limits its use to applications with lower current demands. The RoHS non-compliant status may restrict deployment in regulated environments. This part is appropriate only when AC/DC dual-input functionality is a system requirement and output current demand does not exceed 10mA.

Voltage Range Considerations:

Applications requiring input voltages above 32VDC cannot use either substitute without circuit redesign. The IDC5N's 10–48VDC range is not fully replicated by available alternatives.

Frequently Asked Questions (FAQ)

Q: Can IDC5F directly replace IDC5N in all applications?

A: IDC5F is compatible only if the input voltage supply does not exceed 32VDC. The IDC5N supports up to 48VDC input. Verify your system's supply voltage before substitution.

Q: What is the difference in output current between IDC5F and 70-IDC5NP?

A: IDC5F provides 16mA output current, matching the IDC5N specification. The 70-IDC5NP provides only 10mA output current. Select based on your circuit's current requirements.

Q: Why is switching time different between these parts?

A: IDC5F exhibits significantly faster switching (0.05ms turn-on, 0.10ms turn-off) compared to IDC5N (8ms turn-on, 7ms turn-off). This reflects design improvements in the active product line. Verify that faster switching does not introduce timing conflicts in your application.

Q: Can 70-IDC5NP be used in a DC-only application?

A: Yes. The 70-IDC5NP accepts 10–32VDC input and produces 5VDC output. However, its reduced output current (10mA) and RoHS non-compliant status should be evaluated against system requirements.

Q: What is the packaging difference between these parts?

A: IDC5N packaging is not specified in available data. IDC5F and 70-IDC5NP are supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Are there any compliance differences I should consider?

A: IDC5F is RoHS compliant, suitable for regulated markets. The 70-IDC5NP is RoHS non-compliant. All three parts carry ECCN EAR99 classification and HTSUS 8536.41.0030 tariff code.
