FCE17C37SN400 Equivalent & Substitute Parts

Part Overview

The FCE17C37SN400 is a 37-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features female sockets with a vertical mounting orientation and board-side flange. The connector is classified as Active product status with 791 units currently in stock. D-Sub receptacle connectors serve as mating interfaces in data transmission, industrial control, and legacy equipment applications. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within established parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FCE17C37SN400 is determined by strict alignment of the following critical parameters:

Core Electrical and Mechanical Criteria:

• Connector type: Receptacle, Female Sockets
• Position count: 37 positions
• Row configuration: 2 rows
• Shell size and layout: 4 (DC, C)
• Termination method: Solder
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold
• Flammability rating: UL94 V-0
• Moisture sensitivity: MSL 1 (Unlimited)

Allowable Parameter Variations:

• Current rating: Substitute parts rated at 6A exceed the 5A requirement and remain compatible
• Operating temperature range: Substitute parts with extended ranges (-55°C ~ 105°C) provide broader operational capability
• Voltage rating: Substitute parts with 125V rating are compatible with unspecified voltage applications
• Contact finish thickness: Flash finish on substitute parts is acceptable for gold-plated contacts
• Flange feature: Housing/Shell (Unthreaded) on substitute parts differs from board-side flange but maintains mechanical compatibility for through-hole mounting

The four identified substitute parts meet all core criteria while demonstrating acceptable variations in secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5745189-1 (AMPLIMITE HDP-20 Series)

This substitute part is recommended for applications requiring extended operating temperature range and higher current capacity. The part maintains Active product status with ROHS3 compliance. The 6A current rating and -55°C ~ 105°C operating range exceed the original specification. Through-hole mounting orientation aligns with the FCE17C37SN400 design. Voltage rating of 125V provides additional operational margin. Inventory availability of 1164 units supports supply chain continuity.

TE Connectivity 745189-7 (AMPLIMITE HD-20 Series)

This substitute part offers identical electrical and mechanical specifications to the 5745189-1, with the highest inventory availability at 2246 units. The part maintains Active product status. Note that this part is RoHS non-compliant; selection of this substitute requires confirmation that RoHS compliance is not mandated by application requirements or regulatory constraints.

NorComp 172-037-282-011 and 172-037-282-021

These substitute parts are functionally equivalent 37-position D-Sub receptacles with panel-mount configuration. The mounting type differs from the through-hole orientation of the FCE17C37SN400. These parts are suitable for applications where panel-mount installation is acceptable or preferred. Detailed electrical specifications (current rating, operating temperature, voltage rating) are not provided in available documentation. Selection of NorComp substitutes requires confirmation of mounting compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 745189-7 be used as a direct replacement for the FCE17C37SN400?

A: The 745189-7 meets all core electrical and mechanical specifications for D-Sub 37-position receptacle connectors. However, this part is RoHS non-compliant. Direct substitution is permissible only in applications where RoHS compliance is not required. Verify regulatory and customer requirements before selection.

Q: What is the difference between through-hole and panel-mount configurations?

A: Through-hole mounting (FCE17C37SN400, 5745189-1, 745189-7) installs connectors with leads inserted into printed circuit board holes for solder termination. Panel-mount configuration (172-037-282-011, 172-037-282-021) secures connectors to equipment enclosure panels. These mounting types are not interchangeable without design modification.

Q: Are the NorComp parts suitable substitutes for the Amphenol connector?

A: The NorComp 172-037-282-011 and 172-037-282-021 are 37-position D-Sub receptacles with identical shell size and layout. However, they feature panel-mount configuration rather than through-hole mounting. Substitution is valid only if the application design accommodates panel-mount installation. Additionally, detailed electrical specifications for NorComp parts are not provided; confirmation of current rating and operating temperature compatibility is required.

Q: What does MSL 1 (Unlimited) moisture sensitivity level indicate?

A: MSL 1 (Unlimited) indicates that the connector has no moisture sensitivity restrictions. The component does not require special handling, storage, or baking procedures prior to soldering. All identified substitute parts share this MSL classification.

Q: Why do the TE Connectivity substitutes have higher current ratings (6A vs. 5A)?

A: The 6A current rating on TE Connectivity parts exceeds the 5A specification of the FCE17C37SN400. Higher current ratings indicate greater current-carrying capacity and represent an acceptable parameter variation for substitution purposes. Applications designed for 5A operation remain fully compatible with 6A-rated connectors.

Q: Is the extended operating temperature range of TE Connectivity parts (-55°C ~ 105°C) compatible with the original specification (-40°C ~ 85°C)?

A: Yes. The extended temperature range on TE Connectivity substitutes encompasses the original operating range. Applications designed for -40°C ~ 85°C operation are fully compatible with components rated for -55°C ~ 105°C. The broader range provides additional operational margin without introducing compatibility issues.

Q: What does the 125V voltage rating on TE Connectivity parts indicate?

A: The 125V voltage rating specifies the maximum voltage the connector can safely withstand. The FCE17C37SN400 does not specify a voltage rating. The 125V rating on substitute parts ensures compatibility with standard industrial and commercial voltage applications. This parameter does not restrict substitution eligibility.

Q: How does contact finish thickness (15.0µin vs. Flash) affect connector performance?

A: Both contact finish specifications (15.0µin on the FCE17C37SN400 and Flash on TE Connectivity parts) provide gold plating for corrosion resistance and electrical conductivity. Flash finish represents a thinner gold layer applied to the contact surface. Both finishes are acceptable for D-Sub connector applications and do not affect substitution compatibility.
