L717SDEG09POL2 Equivalent & Substitute Parts
Part Overview
The L717SDEG09POL2 is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products) in the SD series. This through-hole solder-terminated connector features male pins, a board-side M3 flange, and is designed for signal applications in industrial and commercial equipment. The connector is RoHS compliant and rated for 3A at 250V across an operating temperature range of -55°C to 125°C.
Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives that meet or exceed the electrical and mechanical requirements of the original component.

Electrical Parameters (Must Meet or Exceed):
- Current rating must be ≥ 3A
- Voltage rating must be ≥ 250V
- Operating temperature range must encompass -55°C to 125°C or be compatible with application requirements
Compliance Parameters:
- RoHS status and REACH compliance are documented for regulatory traceability
- UL94 V-0 flammability rating is maintained across all substitutes
Mechanical Parameters:

Engineering Selection Recommendations
Primary Substitutes (Recommended for New Designs):
The following parts are recommended as direct substitutes based on active product status, RoHS compliance, and electrical specifications that meet or exceed the original component:
5208006-1 and 5208006-2 (TE Connectivity AMPLIMITE HD-20 series) are the preferred substitutes. Both parts are RoHS compliant, active products with 6A current rating and -55°C to 105°C operating temperature range. These parts provide higher current capacity than the original 3A rating. The 5208006-2 variant offers the highest inventory availability (1,000,200 units) and is suitable for high-volume applications.
1-747871-6 (TE Connectivity AMPLIMITE HD-20 series, Tube packaging) is an active, ROHS3-compliant alternative with 6A current rating. This part is suitable for applications where tube packaging is preferred over bulk or tray formats.
Secondary Substitutes (Conditional Use):
172-E09-113R011, 172-E09-113R021, and 172-E09-113R911 (NorComp 172-E series) are active, ROHS3-compliant products with 5A current rating. These panel-mount variants are suitable for applications requiring panel-mounted configurations. Operating temperature range (-50°C to 100°C) is narrower than the original specification and must be evaluated for compatibility with application requirements.
Not Recommended:
1-747871-4 (TE Connectivity, Bulk packaging) is RoHS non-compliant and not recommended for new designs requiring RoHS compliance.
2-748003-0 (TE Connectivity) is RoHS non-compliant and not recommended for new designs requiring RoHS compliance.
208006-1 (TE Connectivity) is RoHS non-compliant and not recommended for new designs requiring RoHS compliance.
172-009-112R001 (NorComp) is obsolete and not recommended for new designs.
Frequently Asked Questions (FAQ)
Q: Can I substitute a 5208006-1 for an L717SDEG09POL2 in my application?
A: Yes, the 5208006-1 is a functional substitute. Both connectors share the same 9-position D-Sub configuration, shell size (1/DE,E), through-hole solder termination, and male pin design. The 5208006-1 provides higher current capacity (6A vs. 3A) and is RoHS compliant. However, the voltage rating is 125V compared to the original 250V, and the maximum operating temperature is 105°C versus 125°C. Verify that your application does not require the higher voltage or temperature ratings of the original part.
Q: What is the difference between the NorComp 172-E series and the TE Connectivity AMPLIMITE HD-20 series?
A: Both series provide 9-position D-Sub plug connectors with solder termination and UL94 V-0 flammability ratings. The primary differences are: (1) NorComp parts feature panel-mount configurations with board-side flanges, while TE Connectivity parts are standard through-hole with housing-shell or mating-side flanges; (2) NorComp parts use nickel-plated steel shells, while TE Connectivity uses tin-plated steel; (3) NorComp parts have a narrower operating temperature range (-50°C to 100°C) compared to TE Connectivity (-55°C to 105°C); (4) NorComp parts are rated for 5A, while TE Connectivity parts are rated for 6A.
Q: Why do some substitute parts have lower voltage ratings than the original L717SDEG09POL2?
A: The L717SDEG09POL2 is rated for 250V, while most substitute parts (TE Connectivity AMPLIMITE HD-20 series) are rated for 125V. This difference reflects different design specifications and dielectric material selections. For applications operating at voltages below 125V, the substitute parts are fully compatible. For applications requiring 250V operation, only the original part or equivalent 250V-rated alternatives should be used.
Q: Is packaging format (tray, tube, bulk) important for connector compatibility?
A: Packaging format does not affect electrical or mechanical compatibility. Tray, tube, and bulk packaging are logistics and handling considerations only. The connector itself functions identically regardless of packaging. Select packaging based on your procurement, storage, and assembly process requirements.
Q: Can I use a NorComp 172-E09-113R911 with board lock features in place of the L717SDEG09POL2?
A: Yes, the 172-E09-113R911 is mechanically and electrically compatible. The board lock feature (in addition to the standard grounding indents) provides additional mechanical retention and does not prevent substitution. However, this part is configured for panel mounting, whereas the L717SDEG09POL2 is board-side mounted. Verify that your PCB layout and mechanical assembly accommodate the panel-mount flange configuration.
Q: What does RoHS compliance mean for connector selection?
A: RoHS (Restriction of Hazardous Substances) compliance indicates that the connector does not contain restricted materials such as lead, mercury, cadmium, or hexavalent chromium above specified thresholds. For new designs and applications subject to RoHS regulations (particularly in EU markets), select RoHS-compliant parts such as 5208006-1, 5208006-2, 1-747871-6, or the NorComp 172-E series. Non-compliant parts (1-747871-4, 2-748003-0, 208006-1) may be restricted from use in regulated applications.
Q: What is the significance of contact finish thickness (Flash vs. unspecified)?
A: Flash gold plating is a thin layer of gold applied over a nickel or copper underplate, typically 0.05 to 0.25 micrometers thick. This provides corrosion resistance and low contact resistance for signal applications. The L717SDEG09POL2 specifies flash gold finish. Most substitute parts either specify flash gold or do not specify thickness. For signal-level applications, both are acceptable. For high-reliability or high-frequency applications, verify contact finish specifications with the manufacturer.
