L717HDB44PC309

Part Overview

The L717HDB44PC309 is a 44-position D-Sub High Density plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins with solder cup termination and is designed for free-hanging, in-line applications. The component is currently active and stocked at 688 pieces. Alternative models become necessary when application requirements differ in mounting configuration, contact rating capacity, or terminal technology specifications while maintaining core electrical and mechanical compatibility with the 44-position D-Sub HD standard.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717HDB44PC309 with NorComp 180-M series connectors is based on matching the following critical parameters:

• Electrical Compatibility: 44-position configuration, 3-row HD layout, signal contact type, and male pin orientation
• Mechanical Compatibility: D-Sub High Density shell size (3/DB/B), solder cup termination, and grounding indents
• Environmental & Compliance: UL94 V-0 flammability rating, RoHS compliance status, brass contact material with gold finish, and EAR99 ECCN classification

The substitute models differ in the following specified parameters:

• Mounting Configuration: The L717HDB44PC309 is free hanging (in-line); substitute models (180-M44-103L001 and 180-M44-103L011) are panel mount
• Current Rating: The main part is rated at 3A; substitutes are rated at 5A
• Operating Temperature Range: The main part operates from -55°C to 155°C; substitutes operate from -55°C to 105°C
• Shell Finish: The main part uses tin plating; substitutes use nickel plating
• Contact Form: The main part uses stamped contacts; substitutes use machined contacts
• Flange Feature: The main part has unthreaded housing/shell; 180-M44-103L011 features cable-side 4-40 mounting

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active product status and meet UL94 V-0 flammability requirements. Both the main part and substitute models are RoHS compliant (the Amphenol ICC part under RoHS; the NorComp substitutes under ROHS3). All components share EAR99 ECCN classification and are stocked as new original inventory.

Selection between these models depends on specific application mounting requirements:

• L717HDB44PC309 is appropriate for free-hanging, in-line cable assemblies with operating temperatures up to 155°C and 250V applications.
• 180-M44-103L001 is appropriate for panel-mount applications with unthreaded housing requiring standard grounding indents and shielding, rated for 5A continuous current.
• 180-M44-103L011 is appropriate for panel-mount applications with cable-side 4-40 screw mounting, shielding, and 5A current rating at operating temperatures up to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the L717HDB44PC309 be directly replaced with the 180-M44-103L001 or 180-M44-103L011 in all applications?

A: Direct replacement is not universal. While all three connectors share the 44-position D-Sub HD configuration and core electrical specifications, they differ in mounting type. The L717HDB44PC309 is designed for free-hanging (in-line) installations, whereas both NorComp substitutes are panel-mount connectors. Selection requires that your application's mechanical mounting configuration aligns with the chosen connector type.

Q: What are the differences in current rating between these connectors?

A: The L717HDB44PC309 is rated for 3A continuous current, while the 180-M44-103L001 and 180-M44-103L011 are both rated for 5A. If your circuit operates above 3A and up to 5A, the NorComp substitutes provide higher current capacity. If your design is constrained to 3A or below, either part is acceptable.

Q: Are there temperature limitations to consider?

A: The L717HDB44PC309 operates from -55°C to 155°C, providing the widest temperature range. The NorComp substitutes (180-M44-103L001 and 180-M44-103L011) operate from -55°C to 105°C. If your application requires sustained operation above 105°C, the Amphenol part is required. Below 105°C, all three parts are compatible.

Q: What is the difference between 180-M44-103L001 and 180-M44-103L011?

A: Both are NorComp D-Sub HD 44-position plugs with identical electrical and temperature specifications. The key difference is the flange feature: the 180-M44-103L001 has an unthreaded housing/shell flange, while the 180-M44-103L011 includes cable-side 4-40 screw mounting provisions. Select 180-M44-103L011 when your application requires mechanical fixation through cable-side mounting brackets.

Q: Do shell material and finish differences affect electrical performance?

A: Both the tin-plated steel shell (L717HDB44PC309) and nickel-plated steel shells (NorComp substitutes) provide equivalent electrical grounding and shielding performance in these D-Sub connectors. Material and finish selection is typically driven by environmental corrosion resistance requirements or specific design standards rather than baseline electrical function.

Q: What contact finish specifications are provided?

A: The L717HDB44PC309 specifies gold contact finish at 30.0µin (0.76µm) thickness. The NorComp substitutes specify flash gold finish without explicit thickness specification. Both provide gold plating for corrosion resistance and contact reliability. The Amphenol specification provides explicit thickness documentation.
