Amphenol ICC 865637PLTX D-Sub 37-Position Plug Connector

Part Overview

The 865637PLTX is an active D-Sub connector housing designed for male contact termination in 37-position configurations. This plug connector is manufactured by Amphenol ICC (FCI) and serves as a standard interface component in applications requiring D-shaped connector assemblies. The connector operates across an industrial temperature range and supports panel mount installation with unthreaded shell housing.

Equivalent and substitute parts are identified based on matching electrical and mechanical specifications, including connector style, position count, shell size, contact type, and mounting configuration. Alternative sources and packaging options are available to support procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the 865637PLTX are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Connector Style: D-Sub
Connector Type: Plug for Male Contacts
Number of Positions: 37
Number of Rows: 2
Shell Size, Connector Layout: 4 (DC, C)
Contact Type: Signal
Flange Feature: Housing/Shell (Unthreaded)
Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these core compatibility criteria: 865637PLTXLF (Amphenol ICC, direct variant) and 205210-3 (TE Connectivity AMP Connectors, cross-manufacturer equivalent). Both maintain the 37-position D-Sub plug configuration with identical shell sizing and contact architecture.

Engineering Selection Recommendations

The 865637PLTXLF serves as the direct equivalent to the 865637PLTX within the Amphenol ICC product line. Both parts share identical electrical and mechanical specifications. The primary distinction is packaging format (Tray versus Bulk) and RoHS compliance status. The 865637PLTXLF is RoHS Compliant and includes REACH Affected designation, making it suitable for applications with environmental regulatory requirements.

The 205210-3 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 series) qualifies as a cross-manufacturer substitute based on matching connector geometry, position count, and shell configuration. This part is ROHS3 Compliant. The mounting type differs (Free Hanging In-Line versus Panel Mount), which may affect installation methodology depending on application requirements. The dielectric material composition also differs (Polyamide with glass fill versus standard Thermoplastic).

Selection between these substitutes depends on supply availability, compliance certifications required by the end application, and mounting configuration compatibility with the target assembly.

Frequently Asked Questions (FAQ)

Q: Can 865637PLTXLF directly replace 865637PLTX in existing designs?

A: Yes. Both parts maintain identical connector style, position count, shell size, contact type, and flange configuration. The primary differences are packaging format and RoHS compliance status. Electrical and mechanical compatibility is maintained.

Q: What are the key differences between 865637PLTX and 205210-3?

A: Both parts share the same 37-position D-Sub plug configuration and shell sizing. The 205210-3 differs in mounting type (Free Hanging In-Line versus Panel Mount), dielectric material composition (glass-filled polyamide versus thermoplastic), and shell finish (Tin Plated versus Tin/Zinc Plated). These differences may affect installation and environmental performance depending on application requirements.

Q: Are there RoHS compliance considerations when selecting a substitute?

A: Yes. The 865637PLTX is RoHS non-compliant, while 865637PLTXLF is RoHS Compliant and 205210-3 is ROHS3 Compliant. Applications subject to RoHS directives should specify the compliant variants.

Q: Does packaging format affect part compatibility?

A: No. Packaging format (Bulk, Tray) does not affect electrical or mechanical compatibility. Packaging selection is driven by procurement volume, handling requirements, and inventory management practices.

Q: Can 205210-3 be used in panel mount applications?

A: The 205210-3 is specified as Free Hanging (In-Line) mounting type, whereas the 865637PLTX and 865637PLTXLF are Panel Mount. Mounting type compatibility must be verified against specific application installation requirements before substitution.
