L717TSEG09POL2RM8 D-Sub 9-Position Plug Connector: Equivalent & Substitute Parts

Part Overview

The L717TSEG09POL2RM8 is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features male pins, a 1 (DE, E) shell size layout, and mating-side female screwlock (M3) flange. The connector is rated for 5A current at 600V with an operating temperature range of -55°C to 125°C. Product status is Active with 780 units in current inventory.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift between through-hole and panel-mount configurations, or when alternative termination methods (press-fit versus solder) are preferred while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended for Primary Substitution):

The following parts maintain full electrical and mechanical compatibility with the L717TSEG09POL2RM8 within the specified operating envelope:

D09P24A4GX00LF (Amphenol ICC, FCI) and D09P24A4PL00LF (Amphenol ICC, FCI) are the closest electrical equivalents. Both are solder-terminated, through-hole 9-position D-Sub plugs with identical operating temperature range (-55°C to 125°C), matching current rating (5A per contact), and UL94 V-0 flammability rating. D09P24A4PL00LF features M3 mating-side flange matching the original part. Both maintain RoHS compliance and gold contact finish. The primary difference is flange configuration: D09P24A4GX00LF uses 4-40 housing/shell flange, while D09P24A4PL00LF uses M3 housing/shell flange.

09651616713 (HARTING) is electrically compatible with higher current capacity (6.5A versus 5A) and identical operating temperature range. Solder termination and through-hole mounting match the original. Flange feature differs (4-40 mating-side screwlock versus M3). RoHS3 compliance exceeds RoHS compliance requirement. Steel shell without specified finish differs from tin-plated original.

Compatible Alternatives (Acceptable for Secondary Substitution):

172-E09-113R911 (NorComp Inc.) provides dual flange functionality (board side and mating side 4-40 screwlock) with board lock feature matching the original. Solder termination and 5A current rating align with primary part. Operating temperature range (-50°C to 100°C) is narrower than original specification. Panel mount capability adds design flexibility. RoHS3 compliance and gold contact finish are maintained. Nickel-plated steel shell and brass contacts differ from original materials.

172-E09-113R011 (NorComp Inc.) and 172-E09-113R031 (NorComp Inc.) offer panel mount flexibility with solder termination and 5A rating. Both feature board-side or mating-side 4-40 flanges. Operating temperature range (-50°C to 100°C) is narrower. RoHS3 compliance and gold finish are maintained.

5786830-1 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 Series) provides press-fit termination as an alternative to solder. Through-hole mounting and 9-position configuration match original. Operating temperature range (-55°C to 105°C) is slightly narrower at upper limit. RoHS compliance maintained. Press-fit termination eliminates soldering process but requires different PCB pad design. REACH Affected status differs from original.

Compatibility Constraints:

Parts with operating temperature ranges narrower than -55°C to 125°C (specifically the NorComp 172-E series with -50°C to 100°C) are acceptable only when application requirements do not exceed -50°C minimum or 100°C maximum operating conditions.

D09P24A4GX00LF and D09P24A4PL00LF specify 300V voltage rating versus 600V original specification. These parts are acceptable only when application voltage requirements do not exceed 300V.

Frequently Asked Questions (FAQ)

Q: Can I substitute the L717TSEG09POL2RM8 with a part that has a different flange configuration?

A: Yes. The flange feature determines the mechanical mounting interface (mating side, board side, or housing/shell) and screw size (M3 or 4-40). Substitution is acceptable provided the alternative flange configuration is compatible with your PCB layout and mating connector. The electrical function remains unchanged. Verify mechanical clearance and mounting hole alignment before implementation.

Q: What is the difference between solder and press-fit termination?

A: Solder termination requires thermal reflow or wave soldering to attach the connector to PCB pads. Press-fit termination uses mechanical compression to insert contact tails into PCB holes without solder. Both methods provide electrical connection. Press-fit termination (5786830-1) eliminates soldering process but requires different PCB pad hole sizing and design. Solder-terminated parts are standard for most applications.

Q: Are NorComp 172-E series parts fully compatible with the original L717TSEG09POL2RM8?

A: NorComp 172-E series parts (172-E09-113R011, 172-E09-113R031, 172-E09-113R911) are electrically compatible for 9-position D-Sub plug applications. All maintain UL94 V-0 flammability, 5A current rating, solder termination, and RoHS3 compliance. The primary limitation is operating temperature range: -50°C to 100°C versus -55°C to 125°C original. These parts are suitable only when your application operates within -50°C to 100°C limits. Panel mount capability provides additional design flexibility not present in the original through-hole-only configuration.

Q: Why does D09P24A4GX00LF specify 300V while the original part specifies 600V?

A: Voltage rating reflects the maximum voltage the connector can safely withstand without electrical breakdown. D09P24A4GX00LF is rated for 300V maximum. This part is suitable only for applications operating at 300V or below. If your application requires 600V operation, use D09P24A4PL00LF (also 300V) or select 09651616713 (HARTING) which does not specify voltage limitation, or the original L717TSEG09POL2RM8.

Q: Can I use 5786830-1 (press-fit) as a direct replacement for the solder-terminated original?

A: 5786830-1 provides electrical equivalence but requires PCB design changes. Press-fit connectors require different pad hole sizing and plating specifications compared to solder pads. Mechanical insertion force and retention characteristics differ. If your PCB is designed for solder termination, press-fit substitution requires PCB redesign. Press-fit termination is acceptable only when PCB design supports this termination method.

Q: What does RoHS3 compliance mean compared to RoHS compliance?

A: RoHS (Restriction of Hazardous Substances) compliance restricts lead, cadmium, mercury, and other hazardous materials. RoHS3 is the current EU directive (2011/65/EU as amended) with additional restricted substances. RoHS3 compliance exceeds and supersedes RoHS compliance. Parts marked RoHS3 Compliant (NorComp 172-E series, HARTING 09651616713) meet current regulatory requirements and are acceptable substitutes for RoHS Compliant parts.

Q: Is inventory availability a factor in selecting substitute parts?

A: Inventory availability is a practical consideration but not an electrical or mechanical compatibility factor. Current inventory levels are: L717TSEG09POL2RM8 (780 units), 09651616713 (1371 units), 172-E09-113R911 (1938 units), 5786830-1 (1718 units), D09P24A4GX00LF (949 units), D09P24A4PL00LF (1095 units). Higher inventory levels may reduce lead time but do not affect technical suitability.

Q: Can I mix and match different substitute parts in the same assembly?

A: Yes, provided each part meets the electrical and mechanical requirements of its specific connector location. However, maintaining consistent connector series and manufacturer within a single assembly simplifies inventory management, documentation, and future maintenance. Mixed manufacturers are acceptable from a technical standpoint but may complicate supply chain logistics.
