IDC-5F DC Input Module Equivalent & Substitute Parts

Part Overview

The IDC-5F is a DC input module manufactured by TE Connectivity Potter & Brumfield Relays, designed to convert a 4–32VDC supply input into a regulated 5VDC output at 18mA. This module features hold-down screw mounting and is classified as a standard-style DC input module with white coloring. The IDC-5F is currently listed as obsolete, making identification of functionally equivalent substitute parts necessary for ongoing system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IDC-5F is determined by electrical and mechanical parameter alignment within the DC input module category. The critical substitution criteria are:

Electrical Parameters:

• Input voltage range: 4 ~ 32VDC (must match)
• Input current: 68 mA (must match)
• Output voltage: 5VDC (must match)
• Output current: 18mA or greater (equal or higher capacity acceptable)
• Switching response times: Turn On 0.05ms and Turn Off 0.10ms (must match)

Mechanical Parameters:

• Module type: DC Input Module (must match)
• Style: Standard (must match)
• Mounting feature: Hold Down Screw (must match)
• Color: White (must match)

The IDC5F from Sensata-Crydom meets all electrical and mechanical substitution criteria, with the exception of output current specification (16mA versus 18mA). This variance represents a 2mA reduction in output current capacity and must be evaluated against system load requirements.

Parameter Comparison

Engineering Selection Recommendations

The IDC5F from Sensata-Crydom is an active-status substitute for the obsolete IDC-5F. Both modules share identical input voltage range (4–32VDC), input current (68 mA), output voltage (5VDC), and switching response times (0.05ms turn-on, 0.10ms turn-off). Both feature standard-style construction with hold-down screw mounting and white coloring.

The primary distinction between these parts is output current capacity: the IDC-5F delivers 18mA, while the IDC5F delivers 16mA. This 2mA difference must be evaluated against the actual load current requirements of the application. If system loads do not exceed 16mA at 5VDC output, the IDC5F is electrically compatible.

The Sensata-Crydom IDC5F offers additional compliance advantages: it is RoHS Compliant (versus RoHS non-compliant for the original IDC-5F) and carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics. Both parts share identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications.

Frequently Asked Questions (FAQ)

Q: Can the IDC5F (Sensata-Crydom) directly replace the IDC-5F (TE Connectivity)?

A: The IDC5F is electrically and mechanically compatible with the IDC-5F for applications where output current requirements do not exceed 16mA. The 2mA reduction in output current capacity (from 18mA to 16mA) must be verified against system load specifications. All other electrical parameters, switching times, input voltage range, and mechanical features are identical.

Q: What is the significance of the output current difference between these parts?

A: The IDC-5F provides 18mA output current, while the IDC5F provides 16mA. This represents a 2mA reduction in available output current capacity. If the application load draws less than or equal to 16mA at 5VDC, this difference is not functionally significant. If the application requires the full 18mA capacity, the IDC5F is not suitable.

Q: Does the RoHS compliance difference affect substitution?

A: The IDC5F is RoHS Compliant, while the IDC-5F is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the IDC5F provides superior regulatory alignment. This is an advantage of the substitute part, not a limitation.

Q: Are the packaging formats compatible?

A: The IDC-5F is specified with packaging listed as "-" (not specified). The IDC5F is supplied in Bulk packaging. Both modules feature identical mechanical construction with hold-down screw mounting, ensuring physical compatibility in standard mounting applications.

Q: What is the MSL rating difference, and does it matter?

A: The IDC-5F has MSL listed as Not Applicable, while the IDC5F carries an MSL rating of 1 (Unlimited). MSL 1 indicates the component can be stored indefinitely without moisture-related degradation. This represents an improvement in the substitute part's environmental tolerance characteristics.

Q: Are the switching response times identical?

A: Yes. Both the IDC-5F and IDC5F have identical turn-on time (0.05ms) and turn-off time (0.10ms). Switching performance is equivalent between these parts.

Q: Can I use the IDC5F in a new design application?

A: Yes. The IDC5F is an active-status product from Sensata-Crydom, making it suitable for new design implementations. It provides the same electrical functionality as the obsolete IDC-5F, with the exception of the 2mA output current reduction. Verify that your application load does not exceed 16mA at 5VDC output.
