Engineering Selection Recommendations

TE Connectivity AMPLIMITE HD-20 Series (1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, 1-747871-6)

The TE Connectivity AMP Connectors from the AMPLIMITE HD-20 series provide the closest functional equivalence to the L717DEG09POL2RM8. These parts match all primary mechanical and electrical parameters including 9-position configuration, shell size 1 (DE, E), through-hole solder termination, and brass contacts with gold finish. All variants maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level.

Deviations from the main part include reduced current rating (6A versus 7.5A) and lower voltage rating (125V versus 300V). Operating temperature range extends to -55°C but terminates at 105°C compared to 125°C for the main part. Parts 1-5747871-3, 1-5747871-4, and 1-5747871-6 are ROHS3 compliant or RoHS compliant. Part 1-747871-4 is RoHS non-compliant with REACH affected status and should be avoided in applications requiring RoHS compliance. Part 1-747871-6 is ROHS3 compliant with REACH unaffected status.

NorComp 172-E Series (172-E09-113R011, 172-E09-113R021, 172-E09-113R911)

NorComp 172-E series connectors provide functional alternatives with matching 9-position, shell size 1 (DE, E), through-hole solder termination, and brass contacts with gold finish. All three variants are ROHS3 compliant with REACH unaffected status and UL94 V-0 flammability rating.

These parts feature panel mount capability in addition to through-hole mounting, providing design flexibility. Current rating is reduced to 5A and voltage rating is not specified. Operating temperature range is -50°C to 100°C, narrower than the main part. Shell finish is nickel plated rather than tin plated. Part 172-E09-113R911 includes board lock and mating side female screwlock features (4-40), providing additional mechanical retention compared to the main part's board-side M3 flange.

Compliance and Availability Considerations

For applications requiring RoHS compliance, select from TE Connectivity parts 1-5747871-3, 1-5747871-6, 1-747871-6, or NorComp parts 172-E09-113R011, 172-E09-113R021, 172-E09-113R911. Avoid TE Connectivity part 1-747871-4 in RoHS-regulated applications.

For applications requiring REACH compliance, select from TE Connectivity parts 1-5747871-3, 1-5747871-6, 1-747871-6, or NorComp parts 172-E09-113R011, 172-E09-113R021, 172-E09-113R911. Avoid TE Connectivity part 1-747871-4 which is REACH affected.

Inventory availability is highest for TE Connectivity parts, with 4832 units for 1-5747871-3, 3029 units for 1-5747871-4, and 3035 units for 1-5747871-6. NorComp 172-E09-113R011 has 2415 units available.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-5747871-3 directly replace the L717DEG09POL2RM8 in all applications?

A: The 1-5747871-3 matches all primary mechanical parameters and connector configuration. However, the current rating is reduced from 7.5A to 6A, and voltage rating is reduced from 300V to 125V. Applications operating at currents above 6A or voltages above 125V require evaluation of circuit requirements. Operating temperature maximum is 105°C versus 125°C for the main part.

Q: What is the difference between the NorComp 172-E09-113R011 and 172-E09-113R911?

A: Both parts are 9-position D-Sub plugs with matching shell size, termination, and contact specifications. The primary difference is that 172-E09-113R911 includes board lock and mating side female screwlock features (4-40), providing mechanical retention at both board-side and mating-side interfaces. The 172-E09-113R011 has board-side 4-40 flange only. Selection depends on whether dual-side mechanical locking is required in the application.

Q: Are the TE Connectivity AMPLIMITE HD-20 series parts suitable for high-temperature applications?

A: The AMPLIMITE HD-20 series operates to 105°C maximum, which is 20°C lower than the L717DEG09POL2RM8 specification of 125°C. Applications requiring sustained operation above 105°C should not use these substitutes. The NorComp 172-E series also operates to 100°C maximum and is similarly limited for high-temperature applications.

Q: What packaging formats are available for substitute parts?

A: TE Connectivity parts are supplied in tube packaging (1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-6) or bulk packaging (1-747871-4). NorComp parts are supplied in tray packaging. The main part L717DEG09POL2RM8 packaging format is not specified in the provided data. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Do all substitute parts maintain the same flange mounting configuration?

A: The L717DEG09POL2RM8 features board-side M3 flange mounting. TE Connectivity AMPLIMITE HD-20 series parts feature mating-side female screwlock (4-40) flange configuration, which differs from the main part. NorComp 172-E series parts feature board-side 4-40 flange (172-E09-113R011, 172-E09-113R021) or dual board-side and mating-side 4-40 flanges (172-E09-113R911). PCB layout and mechanical mounting design must accommodate these flange configuration differences.

Q: Which substitute part has the highest current rating?

A: The TE Connectivity AMPLIMITE HD-20 series parts (1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, 1-747871-6) have the highest current rating among substitutes at 6A, compared to 5A for NorComp 172-E series. The main part L717DEG09POL2RM8 has 7.5A rating, which exceeds all listed substitutes.

Q: Are there compliance differences between substitute parts?

A: Yes. TE Connectivity part 1-747871-4 is RoHS non-compliant and REACH affected, making it unsuitable for regulated applications. All other substitute parts are ROHS3 compliant or RoHS compliant. NorComp parts have REACH unaffected status. TE Connectivity parts 1-5747871-3, 1-5747871-6, and 1-747871-6 are ROHS3 compliant with REACH unaffected status, providing the highest compliance alignment.
