Engineering Selection Recommendations

Primary Substitute (Equivalent Mounting Configuration):

The 10090769-P444ALF from Amphenol ICC (FCI) maintains the free hanging in-line mounting type identical to the 17EHD044PAM000. Both connectors share the same core D-Sub high density 44-position plug configuration with solder cup termination. The 10090769-P444ALF is actively produced and RoHS compliant. The primary electrical difference is a reduced current rating of 2.5A per contact compared to 3A for the main part, and an elevated voltage rating of 250V versus 125V. The operating temperature range remains -55°C to 105°C. This part is suitable for applications where the in-line mounting geometry is critical to the system design.

Secondary Substitutes (Panel Mount Configuration):

Parts 180-044-103L001 and 180-044-103L021 from NorComp Inc. are actively produced alternatives with panel mount configurations. Both feature nickel-plated steel shells matching the main part's finish specification. These connectors support higher current ratings of 5A and incorporate shielding features. The 180-044-103L001 has an unthreaded housing/shell flange, while the 180-044-103L021 features a cable-side 4-40 flange. Operating temperature range is -50°C to 100°C, representing a narrower specification than the main part. Panel mount geometry requires different PCB or enclosure layout considerations compared to the free hanging configuration.

Obsolete Alternatives (Not Recommended for New Designs):

Parts 180-044-102L001 and 180-044-102L021 from NorComp Inc. carry obsolete product status. While both maintain the 44-position high density D-Sub plug configuration with 5A current rating and tin-plated steel shells, their obsolete classification indicates discontinued production. These parts are listed for reference only in legacy system maintenance scenarios.

Compliance and Regulatory Status:

All active substitute parts maintain RoHS compliance. The 10090769-P444ALF carries RoHS Compliant status with REACH Affected designation. NorComp parts 180-044-103L001 and 180-044-103L021 are ROHS3 Compliant with REACH Unaffected status. All parts carry UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels, indicating suitability for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the 10090769-P444ALF directly replace the 17EHD044PAM000 in existing designs?

A: The 10090769-P444ALF maintains identical mounting type (free hanging in-line), connector configuration (44-position D-Sub high density plug), and termination method (solder cup). Both operate across -55°C to 105°C. The 10090769-P444ALF supports 250V versus the main part's 125V, providing higher voltage margin. However, the current rating is 2.5A per contact compared to 3A for the 17EHD044PAM000. Applications requiring the full 3A per contact specification must evaluate whether 2.5A meets circuit requirements.

Q: What is the primary difference between the NorComp 180-044-103L001 and 180-044-103L021?

A: Both parts are active NorComp products with identical electrical specifications (5A current rating, nickel-plated steel shells, gold contact finish). The functional difference is the flange feature: the 180-044-103L001 has an unthreaded housing/shell flange, while the 180-044-103L021 features a cable-side 4-40 threaded flange. Selection depends on the mechanical mounting requirements of the application.

Q: Why do the NorComp parts have higher current ratings (5A) than the main part (3A)?

A: Current rating is determined by contact geometry, material composition, and thermal design. The NorComp parts use brass contacts versus the copper alloy contacts in the Amphenol parts, and employ different internal construction. Higher current ratings reflect these design differences. Applications should select parts based on actual circuit current requirements rather than assuming higher ratings provide automatic compatibility.

Q: Are the NorComp 180-044-102L001 and 180-044-102L021 suitable for new product designs?

A: Both parts carry obsolete product status, indicating discontinued production. While inventory is available, these parts are not recommended for new designs. Active alternatives include the 180-044-103L001 and 180-044-103L021, which provide equivalent functionality with current production support.

Q: What is the impact of the narrower operating temperature range in NorComp parts (-50°C to 100°C versus -55°C to 105°C)?

A: The NorComp parts operate across a 150°C span compared to the 160°C span of the Amphenol parts. Applications requiring operation below -50°C or above 100°C must use the 17EHD044PAM000 or 10090769-P444ALF. Applications within the -50°C to 100°C window can use either specification.

Q: How does the mounting type difference (free hanging versus panel mount) affect substitution?

A: Mounting type determines physical installation method. Free hanging in-line connectors (17EHD044PAM000 and 10090769-P444ALF) attach directly to cable assemblies without PCB or enclosure mounting. Panel mount connectors (NorComp 180 series) require through-hole or surface mounting on a panel or PCB. These are not interchangeable without redesigning the mechanical interface. Select based on the application's physical layout requirements.

Q: What packaging formats are available for these connectors?

A: The 17EHD044PAM000 is supplied in standard packaging (format not specified in documentation). The 10090769-P444ALF is supplied in trays. NorComp parts (180-044-102L001, 180-044-102L021, 180-044-103L001, 180-044-103L021) are supplied in trays. Tray packaging is standard for high-volume production environments and automated assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 17EHD044PAM000 is RoHS Compliant. The 10090769-P444ALF is RoHS Compliant with REACH Affected status. All NorComp parts are ROHS3 Compliant with REACH Unaffected status. All parts meet current environmental compliance requirements for commercial and industrial applications.
