Key Parameters

Substitute Part Grouping Explanation

Substitution of the L717HDBH44PC309 is based on strict electrical and mechanical compatibility criteria. The substitute parts identified must maintain the following core parameters:

• Connector Type & Position Count: Both substitute parts are 44-position D-Sub high density plugs with male pins, matching the electrical interface requirements
• Row Configuration: All parts maintain 3 rows, ensuring pin layout compatibility
• Shell Size (DB, B) High Density: Identical shell classification across all parts
• Termination Method: Solder cup termination is consistent across main and substitute parts
• Flammability & Compliance: All parts meet UL94 V-0 material flammability rating and RoHS/ROHS3 compliance requirements
• Contact Material & Finish: All parts use brass contacts with gold finish, maintaining electrical performance and corrosion resistance

Differences in mounting type (free hanging vs. panel mount), current rating (3A vs. 5A), operating temperature limits, shell material finish, and contact form do not prevent substitution when the application's specific requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution - L717HDBH44PC309 to 180-M44-103L001 or 180-M44-103L011:

All three parts maintain active product status and full compliance with RoHS/ROHS3 and UL94 V-0 standards. The substitute NorComp parts (180-M44-103L001 and 180-M44-103L011) meet the core electrical and mechanical specifications required for D-Sub 44-position high density connectors.

Key compatibility observations:

1. Both NorComp substitutes provide a higher current rating (5A vs. 3A), making them suitable for applications currently utilizing the 3A rated Amphenol part
2. The operating temperature range of the NorComp parts (-55°C to 105°C) is lower than the Amphenol part (-55°C to 155°C); selection depends on application temperature requirements
3. The Amphenol part is tin plated; NorComp substitutes are nickel plated. Both provide corrosion resistance with identical contact finish specifications
4. Mounting differences (free hanging vs. panel mount) must align with the application's mechanical installation requirements

Selection between the two NorComp alternatives depends on flange feature requirements: 180-M44-103L001 features housing/shell unthreaded flange, while 180-M44-103L011 features cable side (4-40) flange similar to the Amphenol part.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 180-M44-103L001 and 180-M44-103L011 be used interchangeably with the L717HDBH44PC309?

A: Both NorComp parts are electrically and mechanically compatible as substitutes. The primary distinction is the flange feature: 180-M44-103L001 has an unthreaded housing flange, while 180-M44-103L011 has a cable side (4-40) flange. The L717HDBH44PC309 features a cable side (4-40) flange, making 180-M44-103L011 the more direct substitute from a mounting perspective.

Q: What are the implications of the lower operating temperature range for the NorComp substitutes?

A: The NorComp parts operate from -55°C to 105°C, compared to the Amphenol part's -55°C to 155°C range. Applications operating below 105°C fall within both specifications. Applications requiring sustained operation above 105°C require the Amphenol L717HDBH44PC309.

Q: How do the different shell finish materials affect compatibility?

A: The Amphenol part features tin plated steel; the NorComp substitutes feature nickel plated steel. Both finishes provide corrosion resistance. Nickel plating offers superior corrosion resistance in harsh environments and has lower magnetic permeability. Material selection depends on environmental exposure and electromagnetic requirements.

Q: Are there compliance or supply chain advantages to using the NorComp substitutes?

A: Both substitutes maintain ROHS3 compliance, REACH unaffected status (for NorComp), and identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. Supply availability differs: 180-M44-103L001 maintains 1,092 pieces in inventory, while 180-M44-103L011 maintains 771 pieces, compared to 746 pieces for the Amphenol part.

Q: Does the contact form difference (stamped vs. machined) affect electrical performance?

A: The L717HDBH44PC309 uses stamped contacts; the NorComp substitutes use machined contacts. Machined contacts typically provide tighter tolerances and potentially better contact consistency. Both forms are suitable for solder cup termination applications and maintain gold finish specifications for electrical conductivity and corrosion resistance.
