L717SDEG09POL2RM8 D-Sub 9-Position Plug Connector - Equivalent & Substitute Parts
Part Overview
The L717SDEG09POL2RM8 is a 9-position D-Sub plug connector manufactured by Amphenol ICC, designed for through-hole solder termination applications. This connector features male pins, vertical orientation, and board-side M3 mounting with mating-side female screwlock (M3). The part is currently active in production with 800 units in stock.
Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required, or when design flexibility permits selection from qualified equivalent connectors that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution eligibility for the L717SDEG09POL2RM8 is determined by the following critical parameters:
- Connector Type & Position Count: Must be D-Sub plug with 9 positions, 2 rows, male pins
- Shell Size & Layout: Must be Size 1 (DE, E) configuration
- Mounting Type: Must support through-hole solder termination
- Electrical Ratings: Current rating must be equal to or greater than 3A; voltage rating must be equal to or greater than 250V
- Operating Temperature Range: Must encompass or exceed -55°C to 125°C
- Flammability & Compliance: Must meet UL94 V-0 rating; RoHS compliance status is noted but does not preclude substitution
- Mechanical Interface: Flange features and mating-side configurations must be compatible with the application
Substitute parts are grouped into two categories:
Category A - Direct Electrical Equivalents (Higher Current Rating): TE Connectivity AMPLIMITE HD-20 series (1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, 1-747871-6) and TE Connectivity 2-5748003-0. These parts exceed the 3A current requirement (rated 6A) but operate at lower voltage (125V) and reduced temperature range (-55°C to 105°C).
Category B - Mechanical Variants (Panel Mount Options): NorComp 172 series (172-009-112R001, 172-E09-113R011, 172-E09-113R021, 172-E09-113R911). These parts support panel mount in addition to through-hole mounting, with 5A current rating and reduced operating temperature range (-50°C to 100°C).

Engineering Selection Recommendations
TE Connectivity AMPLIMITE HD-20 Series (1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, 1-747871-6)
These connectors are electrically superior to the L717SDEG09POL2RM8, with 6A current rating versus 3A. All variants maintain UL94 V-0 flammability compliance and active product status. The primary trade-off is reduced voltage rating (125V versus 250V) and narrower operating temperature range (-55°C to 105°C versus -55°C to 125°C). Parts 1-5747871-3, 1-5747871-4, and 1-5747871-6 are ROHS3 or RoHS compliant. Part 1-747871-4 is RoHS non-compliant and REACH affected; part 1-747871-6 is ROHS3 compliant and REACH unaffected. Selection among these variants depends on regulatory requirements and packaging preference (tube or bulk).
TE Connectivity 2-5748003-0
This part offers 6A current rating with board lock and grounding indents matching the original design. It is ROHS3 compliant and active in production. Voltage and temperature specifications match the AMPLIMITE HD-20 series. Packaging is tray format, consistent with the original part.
NorComp 172 Series (172-009-112R001, 172-E09-113R011, 172-E09-113R021, 172-E09-113R911)
These connectors support both panel mount and through-hole configurations, offering design flexibility. Current rating is 5A, meeting the 3A requirement. All maintain UL94 V-0 compliance. Operating temperature range is -50°C to 100°C, which does not extend to the original -55°C lower limit. Part 172-009-112R001 is obsolete; the 172-E series variants are active. Parts 172-E09-113R011, 172-E09-113R021, and 172-E09-113R911 are ROHS3 compliant. Selection among NorComp variants depends on flange configuration requirements (board side, mating side, or dual-side locking).
Frequently Asked Questions (FAQ)
Q: Can I substitute a TE Connectivity AMPLIMITE HD-20 connector for the L717SDEG09POL2RM8?
A: Yes, with electrical and thermal considerations. The AMPLIMITE HD-20 series provides higher current capacity (6A versus 3A) and maintains the same 9-position, Size 1 D-Sub configuration with through-hole solder termination. However, the voltage rating is reduced to 125V (from 250V), and the maximum operating temperature is 105°C (from 125°C). Substitution is valid only if your application does not require the full 250V rating or operation above 105°C.
Q: What is the difference between the NorComp 172-E09-113R011 and 172-E09-113R911?
A: Both are 9-position D-Sub plugs with identical electrical and thermal specifications. The primary difference is the flange feature: 172-E09-113R011 has board-side (4-40) mounting only, while 172-E09-113R911 includes both board-side (4-40) and mating-side female screwlock (4-40), providing board lock capability. Select 172-E09-113R911 if your design requires mechanical locking between mating connectors.
Q: Why does the L717SDEG09POL2RM8 have a higher voltage rating than the TE Connectivity substitutes?
A: The L717SDEG09POL2RM8 is rated for 250V, while TE Connectivity AMPLIMITE HD-20 and 2-5748003-0 are rated for 125V. This reflects different design specifications and dielectric material properties. The original part is suitable for higher-voltage applications; substitutes are appropriate only for applications operating at 125V or below.
Q: Are all substitute parts RoHS compliant?
A: Most substitute parts are RoHS or ROHS3 compliant. Exception: TE Connectivity 1-747871-4 is RoHS non-compliant and REACH affected. If RoHS compliance is mandatory, select from 1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-6, 2-5748003-0, or any NorComp 172-E variant.
Q: What is the difference between tube and tray packaging?
A: Tube packaging is a continuous reel format suitable for automated assembly processes. Tray packaging is a flat format suitable for manual handling and smaller production runs. The connector specifications are identical; packaging choice depends on assembly method and volume requirements.
Q: Can I use the NorComp 172-009-112R001 as a substitute?
A: The 172-009-112R001 meets the mechanical and electrical requirements but is marked as obsolete. While it may be available in inventory, it is not recommended for new designs. Active alternatives within the NorComp 172-E series are preferred.
Q: What is the operating temperature limitation of the substitute parts?
A: TE Connectivity AMPLIMITE HD-20 and 2-5748003-0 are rated -55°C to 105°C. NorComp 172 series is rated -50°C to 100°C. The original L717SDEG09POL2RM8 extends to 125°C. If your application requires operation above 105°C, the original part or a higher-temperature alternative must be selected.
