L717DFE09PT

Part Overview

The L717DFE09PT is a 9 Position D-Sub Plug connector manufactured by Amphenol ICC (Commercial Products), featuring male pins with panel mount, through-hole solder termination. This connector is actively manufactured and stocked (782 pcs available). The DF Series connector operates across the -55°C to 125°C temperature range with a 7.5A current rating and 300V voltage rating, supporting standard applications requiring D-Sub connectivity in industrial and commercial equipment.

Substitute parts become necessary when stock availability is limited, preferred packaging alternatives are required, or operational parameters allow for cross-compatibility with alternative manufacturers' offerings while maintaining electrical and mechanical compliance.

Shell Size: 1 (DE, E) D-Sub layout
Termination Method: Solder
Contact Material: Brass with Gold finish
Material Flammability Rating: UL94 V-0
Moisture Sensitivity Level: MSL 1 (Unlimited)

Allowable Parameter Variations:

Mounting Type: Panel Mount (primary) or Through Hole (alternative) — both support the same interface geometry
Shell Material Finish: Steel with Tin or Nickel plating (both provide equivalent protection)
Current Rating: 7.5A (primary) down to 5A-6A (allows applications with reduced current density)
Voltage Rating: 300V (primary) down to 125V (accommodates standard signal-level applications)
Operating Temperature Range: -55°C to 125°C (primary) or -55°C to 105°C or -50°C to 100°C (accommodates most industrial environments)
Packaging: Tray, Tube, or Bulk formats are electrically equivalent

Substitute parts must match the D-Sub 9-position, 2-row male plug configuration with solder termination, brass contacts with gold finish, and UL94 V-0 flammability rating.

Engineering Selection Recommendations

Tier 1 - Preferred Substitutes (Active, RoHS3 Compliant, Equivalent Electrical Parameters):

1-5747871-3, 1-5747871-4, 1-5747871-6 (TE Connectivity AMPLIMITE HD-20 Series): These connectors are actively manufactured with RoHS3 compliance. The primary difference is Through Hole mounting versus Panel Mount on the original, and reduced current rating (6A vs. 7.5A). These are suitable for applications where the 6A rating accommodates the circuit design and panel mounting is not a design constraint.
2-5748003-0 (TE Connectivity AMPLIMITE HD-20 Series): Active production with ROHS3 compliance. Includes Board Lock feature and Housing/Shell (4-40) flange for additional mechanical retention. Current rating of 6A and voltage rating of 125V are within acceptable parameters for standard signal-level applications.

Tier 2 - Secondary Substitutes (Active, RoHS3 Compliant, Panel Mount Available):

172-E09-113R011, 172-E09-113R021, 172-E09-113R911 (NorComp Inc. 172-E Series): These connectors maintain Panel Mount, Through Hole mounting compatibility with the original. All are actively produced with RoHS3 compliance. The 172-E09-113R911 includes Board Lock and dual flange features (Board Side and Mating Side screwlock). Current rating of 5A and unspecified voltage rating require confirmation for high-voltage applications exceeding 125V. Operating temperature range is -50°C to 100°C, which is narrower than the original -55°C to 125°C specification.

Tier 3 - Not Recommended:

1-747871-4 (TE Connectivity): RoHS non-compliant status disqualifies this part from applications subject to RoHS directives.
172-009-112R001 (NorComp Inc.): Obsolete product status and discontinued manufacturing support make this unsuitable for new designs.

Compliance Considerations: All recommended substitutes maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification, matching the original specification. The primary regulatory distinction is RoHS compliance status, with Tier 1 and Tier 2 parts meeting RoHS3 requirements suitable for global market applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute an L717DFE09PT with a TE Connectivity 1-5747871 series part? A: Yes, with electrical parameter consideration. The 1-5747871 series (variants -3, -4, -6) provide equivalent D-Sub 9-position, 2-row male plug connectivity with solder termination and brass gold-plated contacts. The primary difference is the mounting type change from Panel Mount to Through Hole, and a reduced current rating of 6A versus the original 7.5A. If your application requires maximum current above 6A or specifically requires panel mounting, verify these parameters before substitution.

Q: What is the difference between 1-5747871-3, 1-5747871-4, and 1-5747871-6? A: These are electrically equivalent parts differing only in packaging format and manufacturing lot/revision coding. All three variants feature identical connector specifications: 9-position D-Sub male plug, Through Hole mounting, 6A current rating, 125V voltage rating, and steel tin-plated shell with gold-plated brass contacts. Selection between variants should be based on available inventory and packaging preference (Tube packaging in this series).

Q: Can I use a NorComp 172-E09-113R011 in place of the L717DFE09PT? A: Yes, for applications within the specified operating parameters. The 172-E09-113R011 maintains Panel Mount, Through Hole compatibility, 9-position D-Sub male plug configuration, and solder termination with brass gold-plated contacts. Key differences are a reduced current rating (5A vs. 7.5A), narrower operating temperature range (-50°C to 100°C vs. -55°C to 125°C), and nickel-plated shell finish instead of tin-plated. Confirm your application does not require operation below -50°C or above 100°C, and verify current density is within 5A limits.

Q: What does the 172-E09-113R911 variant offer compared to other NorComp options? A: The 172-E09-113R911 includes additional mechanical retention features: Board Lock mechanism and dual flange design (both Board Side and Mating Side 4-40 screwlock). This provides enhanced vibration resistance and mechanical stability. All other electrical parameters (9-position D-Sub male plug, 5A current, solder termination, gold-plated contacts) remain consistent with the 172-E09-113R011 and 172-E09-113R021 variants.

Q: Are there packaging format differences among substitutes? A: Yes. The original L717DFE09PT is supplied in Tray packaging. Substitute parts are available in Tray (172 series, 2-5748003-0), Tube (1-5747871-3, 1-5747871-6, 1-747871-6), or Bulk (1-747871-4) formats. Packaging does not affect electrical or mechanical compatibility; selection depends on assembly process requirements and order quantity. Verify packaging format aligns with automated assembly or manual insertion equipment specifications.

Q: Which substitute has the broadest operating temperature range? A: The TE Connectivity AMPLIMITE HD-20 variants (1-5747871-3, 1-5747871-4, 1-5747871-6) and 2-5748003-0 all operate from -55°C to 105°C, matching the lower temperature limit of the original -55°C specification. The NorComp 172 series parts operate from -50°C to 100°C, which is more restrictive. The original L717DFE09PT operates to 125°C upper limit, which is higher than all active substitutes; this parameter should be verified for high-temperature applications.

Q: Should I avoid the 172-009-112R001 NorComp part? A: Yes. This part has Obsolete product status, indicating it has been discontinued by the manufacturer. Obsolete parts present supply chain risk and may lack technical support. New designs should utilize Active production parts from Tier 1 or Tier 2 recommendations.

Q: What is the significance of RoHS compliance differences? A: RoHS Compliant and ROHS3 Compliant parts are suitable for markets with environmental and hazardous substance restriction directives. The 1-747871-4 is marked RoHS non-compliant and should not be used in applications subject to RoHS regulatory requirements (EU, China, and other territories). All other substitutes meet RoHS3 standards, providing regulatory compliance across global markets.
