L717DEG09POL2 Equivalent & Substitute Parts Reference
Part Overview
The L717DEG09POL2 is a 9-position D-Sub plug connector manufactured by Amphenol ICC with vertical through-hole solder termination. This connector features male pins, board-side M3 flange, tin-plated steel shell, and gold-plated contacts. The part is currently active in production with 914 units in stock.
Equivalent and substitute parts are identified when design requirements permit component interchange based on matching electrical and mechanical parameters. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required for supply chain optimization.

Engineering Selection Recommendations
Tier 1 Direct Substitutes (Highest Compatibility):
The TE Connectivity AMPLIMITE HD-20 series parts (1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, 1-747871-6) provide the closest functional equivalence to the L717DEG09POL2. These parts match all primary substitution criteria with the following considerations:
- Current rating of 6A is acceptable for applications rated at or below 6A; applications requiring the full 7.5A rating of the main part require thermal analysis
- Voltage rating of 125V is suitable for standard signal applications; applications exceeding 125V require the main part
- Operating temperature range of -55°C to 105°C covers most industrial applications; thermal derating applies above 105°C
- All parts carry RoHS3 compliance or RoHS compliance status
- Mating-side female screwlock flange differs from board-side M3 flange; mechanical integration must be verified
Tier 2 Substitutes (Conditional Compatibility):
The TE Connectivity AMPLIMITE HDP-20 part (1-338309-2) is suitable for applications where voltage rating specification is not critical and current requirements do not exceed 6A. This part features board-side 4-40 flange mounting, which may require mechanical redesign compared to the M3 flange of the main part.
Tier 3 Substitutes (Limited Compatibility):
NorComp Inc. 172-E series parts (172-E09-113R001, 172-E09-113R011) are suitable only for panel-mount applications. The 5A current rating and -50°C to 100°C operating range restrict use to lower-power signal applications. These parts are not recommended for direct replacement in through-hole board-mount applications.
Not Recommended:
The HARTING 09642217230 (15-position) and NorComp 172-009-112R001 (obsolete status) do not meet primary substitution criteria and are not suitable replacements.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 1-5747871-3 replace the L717DEG09POL2 in all applications?
A: The 1-5747871-3 matches all primary electrical and mechanical parameters except current rating (6A vs. 7.5A) and operating temperature upper limit (105°C vs. 125°C). Substitution is valid for applications operating at or below 6A and 105°C. Applications requiring the full 7.5A rating or operation above 105°C require the original part or thermal analysis to confirm derating is acceptable.
Q: What is the difference between board-side and mating-side flange configurations?
A: Board-side flange (M3) on the L717DEG09POL2 mounts directly to the PCB with M3 fasteners. Mating-side female screwlock flange on TE Connectivity parts mounts to the mating connector shell. Mechanical integration differs; connector orientation and mounting hole patterns must be verified before substitution.
Q: Are NorComp 172-E series parts suitable for through-hole board mounting?
A: NorComp 172-E series parts feature panel-mount configuration with through-hole capability. These parts are designed for panel cutout mounting rather than direct PCB board-side mounting. Substitution requires mechanical redesign of the mounting interface and is not recommended for direct replacement.
Q: What compliance certifications must be maintained during substitution?
A: The L717DEG09POL2 is RoHS Compliant with UL94 V-0 flammability rating. All substitute parts must maintain RoHS Compliant or ROHS3 Compliant status and UL94 V-0 material flammability rating. Compliance status is provided in the parameter comparison table.
Q: Can I use a substitute part with lower voltage rating in a 300V application?
A: No. The L717DEG09POL2 is rated for 300V operation. Substitute parts with 125V or unspecified voltage ratings are not suitable for applications exceeding their rated voltage. The original part or equivalent 300V-rated connector must be used.
Q: What is the significance of contact finish thickness specifications?
A: The L717DEG09POL2 specifies 8.00µin (0.203µm) gold contact finish thickness. TE Connectivity parts specify "Flash" or no thickness value. Flash plating provides minimal corrosion protection suitable for signal-level applications. For high-reliability or corrosive environment applications, contact finish thickness should be verified with the manufacturer.
Q: Are there packaging differences between substitute parts?
A: Yes. The L717DEG09POL2 is supplied in Tray packaging. TE Connectivity substitutes are available in Tube or Bulk packaging. Packaging affects handling, storage, and automated assembly compatibility. Verify packaging requirements for your manufacturing process before ordering.
