L717DFEH09POL2VF2 Equivalent & Substitute Parts

Part Overview

The L717DFEH09POL2VF2 is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This panel mount, through-hole solder connector features male pins with a 2-row configuration in shell size 1 (DE, E). The connector is designed for signal applications with a current rating of 7.5A and voltage rating of 300V, operating across a temperature range of -55°C to 155°C. The product is currently active and RoHS compliant with UL94 V-0 flammability rating.

Equivalent and substitute parts are necessary when the original component becomes unavailable, when alternative sourcing is required for cost optimization, or when design flexibility permits the use of functionally compatible alternatives that meet application requirements.

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict alignment of core electrical and mechanical parameters. The following parameters must match or be compatible for a part to function as a substitute:

Critical Matching Parameters:

Connector style (D-Sub)
Connector type (Plug, Male Pins)
Number of positions (9)
Number of rows (2)
Shell size and layout (1 / DE, E)
Termination method (Solder)
Contact material (Brass)
Material flammability rating (UL94 V-0)

Compatibility Considerations:

Current rating must equal or exceed the application requirement (7.5A minimum)
Voltage rating must equal or exceed the application requirement (300V minimum)
Operating temperature range must encompass the application environment (-55°C to 155°C)
Mounting type variations (panel mount vs. through-hole) affect physical installation but do not prevent functional substitution if the connector footprint is compatible

Substitute parts are grouped based on mounting configuration and flange feature differences, which affect board-level integration but maintain electrical compatibility within the D-Sub 9-position plug category.

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS Compliant):

The TE Connectivity AMPLIMITE HD-20 series connectors (1-5747871-3, 1-5747871-4, 1-5747871-6, and 2-5748003-0) are functionally compatible alternatives. These parts maintain the same D-Sub 9-position plug configuration, shell size, and solder termination. However, these substitutes operate at a maximum voltage of 125V and current rating of 6A, which are lower than the main part's 300V and 7.5A ratings. These substitutes are suitable for applications where the electrical requirements do not exceed 125V and 6A. All listed TE Connectivity parts maintain active product status and RoHS compliance.

Secondary Substitutes (Active Status, Panel Mount Configuration):

The NorComp 172-E series connectors (172-E09-113R011, 172-E09-113R021, and 172-E09-113R911) provide panel mount configuration matching the main part. These connectors are active products with ROHS3 compliance. The 172-E09-113R911 variant includes both board-side and mating-side flange features with board lock capability. Current rating is 5A and voltage rating is not specified. Operating temperature range is -50°C to 100°C, which is narrower than the main part.

Not Recommended:

The NorComp 172-009-112R001 has obsolete product status and should not be selected for new designs. The TE Connectivity 1-747871-4 is RoHS non-compliant and should not be used in applications requiring RoHS compliance. The 1-747871-6 is ROHS3 compliant but carries REACH Affected status, requiring additional regulatory assessment.

Selection Criteria Summary:

For applications requiring 300V and 7.5A ratings: No direct substitute exists; the main part L717DFEH09POL2VF2 is required.
For applications with maximum 125V and 6A requirements: TE Connectivity AMPLIMITE HD-20 series (1-5747871-3, 1-5747871-4, 1-5747871-6, 2-5748003-0) are suitable.
For panel mount applications with lower electrical requirements: NorComp 172-E series (172-E09-113R011, 172-E09-113R021, 172-E09-113R911) are suitable.
All recommended substitutes maintain UL94 V-0 flammability rating and brass contact material.

Frequently Asked Questions (FAQ)

Q: Can I use a TE Connectivity AMPLIMITE HD-20 connector as a direct replacement for the L717DFEH09POL2VF2?

A: The TE Connectivity AMPLIMITE HD-20 series (1-5747871-3, 1-5747871-4, 1-5747871-6) shares the same D-Sub 9-position plug configuration, shell size, and solder termination. However, these parts have a maximum voltage rating of 125V and current rating of 6A, compared to the main part's 300V and 7.5A. Substitution is only valid if your application operates within these lower electrical limits.

Q: What is the difference between the TE Connectivity parts 1-5747871-3, 1-5747871-4, and 1-5747871-6?

A: These three parts are variants within the AMPLIMITE HD-20 series with identical electrical and mechanical specifications. The differences are in packaging (all are tube packaged) and internal part numbering. All three are active products with RoHS compliance and are functionally equivalent for substitution purposes.

Q: Why does the NorComp 172-009-112R001 appear in the substitute list if it is obsolete?

A: The 172-009-112R001 is listed for reference purposes only and is not recommended for new designs. Its obsolete status indicates that the manufacturer has discontinued production. For new applications, select from active product alternatives such as the NorComp 172-E series or TE Connectivity AMPLIMITE HD-20 series.

Q: Are the NorComp 172-E series connectors suitable for high-temperature applications?

A: The NorComp 172-E series has an operating temperature range of -50°C to 100°C, which is narrower than the main part's -55°C to 155°C range. These connectors are not suitable for applications requiring operation above 100°C or below -50°C.

Q: What is the significance of the flange feature differences between substitute parts?

A: Flange features determine how the connector mounts to the circuit board or panel. The main part L717DFEH09POL2VF2 has board-side flange (4-40) and mating-side female screwlock (4-40). The TE Connectivity through-hole variants have different flange configurations (housing/shell or mating-side only), which affects mechanical mounting but does not impact electrical compatibility. The NorComp 172-E series maintains board-side flange (4-40) configuration, providing closer mechanical compatibility.

Q: Can I substitute a connector with a lower current rating if my application uses less current?

A: Yes, a connector with a lower current rating can be used if the actual application current does not exceed the substitute part's rating. For example, if your application draws 5A, the NorComp 172-E series (5A rating) is suitable, even though the main part is rated for 7.5A. However, the substitute must still meet or exceed all other electrical requirements, including voltage rating.

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. If your application or market requires RoHS compliance, select only from parts with RoHS Compliant or ROHS3 Compliant status. Avoid parts marked as RoHS non-compliant or with undefined RoHS status.

Q: Are there any packaging differences between the substitute parts?

A: Yes, substitute parts are available in different packaging formats: Tube, Tray, and Bulk. Packaging affects order quantities and handling but does not impact electrical or mechanical performance. Select packaging based on your procurement requirements and inventory management practices.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: Both tin-plated and nickel-plated finishes provide corrosion resistance for the steel shell. Tin plating is more common and provides good solderability. Nickel plating offers enhanced corrosion resistance in harsh environments. The choice between them depends on environmental exposure and application requirements. The main part uses tin plating; NorComp 172-E series uses nickel plating.
