Substitute Part Grouping Explanation

Substitution of the L717SDEG09POL2RM5 is evaluated against the following critical parameters:

Electrical Compatibility: Number of positions (9), number of rows (2), shell size (1/DE-E), connector type (Plug with Male Pins), contact material (Brass), and contact finish (Gold) must remain constant. Current and voltage ratings are application-dependent and may increase but not decrease from the main part specification.

Mechanical Compatibility: Mounting type (Through Hole), termination method (Solder), shell material (Steel), and flange configuration (Board Side) determine physical fit and installation method. Variations in flange feature design (e.g., M3 vs. 4-40 mounting holes vs. unthreaded) affect board integration and must be evaluated against specific PCB hole patterns.

Environmental & Regulatory: Operating temperature range, flammability rating (UL94 V-0), and RoHS/REACH compliance status are selection criteria for system-level requirements. Temperature operating ranges that exceed the main part specification provide flexibility, while compliance statuses must meet or exceed application requirements.

Packaging: Form factor (Tray, Tube, Bulk) affects logistics and inventory management but does not impact electrical or mechanical performance.

Substitute parts are valid when all electrical parameters match or exceed the main part, mechanical mounting configurations are equivalent or compatible, and environmental/regulatory status meets or exceeds requirements.

Engineering Selection Recommendations

Primary Substitutes (Equivalent Compliance & Status):

TE Connectivity AMPLIMITE HD-20 series parts (1-5747871-3, 1-5747871-4, 1-5747871-6, 2-5748003-0) and 1-747871-6 are active products with ROHS3 or RoHS compliance matching or exceeding the main part. These connectors share identical electrical topology (9-position, shell size 1, solder termination, male pins) and differ primarily in flange configuration and dielectric material. The AMPLIMITE HD-20 series offers higher current rating (6A vs. 3A) within the same voltage class and operating temperature envelope. Flange differences require PCB hole pattern evaluation: main part uses M3 board-side mounting, while TE Connectivity alternatives employ 4-40 screwlock features (mating-side or housing-mounted). The 2-5748003-0 variant includes board-lock features matching the main part topology.

Secondary Substitutes (Temperature/Compliance Considerations):

NorComp 172-E series (172-E09-113R011, 172-E09-113R021, 172-E09-113R911) provide active-status alternatives with ROHS3 compliance but operate at reduced maximum temperature (-50°C to 100°C vs. -55°C to 125°C). These connectors feature board-side or dual-flange 4-40 mounting and nickel-plated steel shells. The 172-E09-113R911 variant combines both board-side and mating-side flanges, providing dual-interface capability. Operating temperature and shell finish differences require application assessment.

Not Recommended:

1-747871-4 carries RoHS non-compliant status and is not recommended for new designs requiring regulatory compliance. NorComp 172-009-112R001 is obsolete and operates at reduced temperature range (-50°C to 100°C); its use should be avoided except for legacy equipment maintenance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different flange mounting holes?

A: No. Flange configuration directly impacts printed circuit board hole patterns and mounting compatibility. The main part uses M3 board-side mounting, while many substitutes employ 4-40 or unthreaded alternatives. Mechanical compatibility must be verified against your specific PCB design before selection.

Q: Are TE Connectivity AMPLIMITE HD-20 parts drop-in replacements?

A: Electrically yes, mechanically conditional. These parts share identical 9-position, shell-size-1 topology and solder termination. However, flange features differ: main part is M3 board-side, while AMPLIMITE variants use mating-side screwlock or housing-mounted 4-40 holes. Board design must accommodate the mounting configuration.

Q: Why is the main part rated at 3A while some substitutes are rated 6A?

A: Current rating reflects conductor cross-section and contact design. Higher-rated substitutes (6A) provide increased current capacity within the same connector envelope. Applications operating below the substitute part's rating benefit from increased margin.

Q: Can I use NorComp 172-E series if my application operates below -50°C?

A: No. The main part operates to -55°C while NorComp 172-E series minimum is -50°C. Applications requiring -55°C operation must use the main part or equivalent TE Connectivity alternatives rated to -55°C.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both indicate hazardous substance restriction compliance. RoHS (RoHS 1) and ROHS3 (RoHS 2 and RoHS 3) represent sequential regulatory updates. ROHS3 represents the current regulatory standard. Both statuses meet modern regulatory requirements; ROHS3 designation indicates compliance with latest criteria.

Q: Is packaging (Tray vs. Tube vs. Bulk) electrically significant?

A: No. Packaging format affects logistics and storage only. Electrical and mechanical performance remains identical across packaging types. Selection should prioritize connector specifications and flange compatibility.

Q: Which substitute offers the best thermal performance?

A: The main part (L717SDEG09POL2RM5) and TE Connectivity AMPLIMITE HD-20 variants (1-5747871-3, 1-5747871-4, 1-5747871-6) both operate to 125°C and 105°C respectively, with AMPLIMITE variants operating to 105°C maximum. For applications requiring maximum temperature operation, the main part is specified.
