L717DEF09P D-Sub 9-Position Plug Connector - Equivalent & Substitute Parts

Part Overview

The L717DEF09P is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This connector features male pins with solder cup termination and is designed for free-hanging (in-line) mounting applications. The part is currently in active production status with 941 pieces available in inventory.

D-Sub connectors in this category are essential for applications requiring standardized signal transmission interfaces. When the primary part becomes unavailable, obsolete, or when design requirements necessitate alternative specifications, equivalent substitute parts must be selected based on strict electrical and mechanical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L717DEF09P are identified based on the following mandatory compatibility criteria:

Primary Compatibility Requirements:

• Connector Type: Plug, Male Pins (fixed)
• Number of Positions: 9 (fixed)
• Shell Size, Connector Layout: 1 (DE, E) (fixed)
• Termination: Solder Cup (fixed)
• Contact Type: Signal (fixed)

Secondary Compatibility Parameters:

• Current Rating: Minimum 5A (L717DEF09P rated at 7.5A)
• Voltage Rating: Minimum 300V (L717DEF09P rated at 300V)
• Operating Temperature Range: Must encompass or match -55°C ~ 125°C
• Contact Finish: Gold or equivalent corrosion-resistant finish
• RoHS Compliance: Required for regulatory alignment

Variable Parameters Allowing Substitution:

• Mounting Type: Free Hanging (In-Line) or Panel Mount (functional difference, not electrical incompatibility)
• Shell Material Finish: Steel with Tin or equivalent plating
• Dielectric Material: Thermoplastic or PBT variants acceptable
• Contact Material: Brass or Copper Alloy acceptable
• Packaging: Bag, Tray, or Bulk (does not affect connector function)
• Color: Cosmetic variation, does not affect electrical performance

Two substitute parts meet these criteria with documented compatibility.

Parameter Comparison

Engineering Selection Recommendations

DEP09P065TXLF (Amphenol ICC FCI Series DP)

This substitute is electrically and mechanically equivalent to the L717DEF09P with enhanced specifications. Both parts share identical mounting type (free hanging in-line), current rating (7.5A), operating temperature range (-55°C ~ 125°C), and shell configuration (1 DE/E). The DEP09P065TXLF features a higher voltage rating (1000V versus 300V) and thicker gold plating (30.0µin versus 8.00µin), providing superior performance margins. Both parts are RoHS compliant and currently in active production. This substitute is suitable for direct replacement in applications where the L717DEF09P is unavailable.

172-009-102R031 (NorComp Inc. 172 M Series)

This substitute meets core electrical compatibility requirements but with operational constraints. The part shares the same 9-position, DE/E shell configuration and solder cup termination. However, three parameters differ: (1) mounting type is panel mount rather than free hanging in-line, requiring mechanical redesign; (2) current rating is 5A versus 7.5A, limiting maximum current per contact; (3) operating temperature range is -50°C ~ 100°C, narrower than the main part's -55°C ~ 125°C specification. Additionally, this part is marked as obsolete, indicating discontinued production. Selection of this substitute requires design modification and is not recommended for new designs or direct replacement scenarios.

Frequently Asked Questions (FAQ)

Q1: Can DEP09P065TXLF be used as a direct replacement for L717DEF09P?

A: Yes. Both connectors are 9-position D-Sub plugs with identical shell size (1 DE/E), free-hanging in-line mounting, solder cup termination, and 7.5A current rating. Operating temperature ranges are identical (-55°C ~ 125°C). The DEP09P065TXLF features enhanced voltage rating (1000V) and thicker gold plating, making it functionally superior. No design modification is required.

Q2: Why is 172-009-102R031 listed as a substitute if it has different mounting type?

A: The 172-009-102R031 meets core electrical compatibility criteria (9-position, DE/E shell, solder cup termination, signal contact type). However, the panel mount configuration represents a mechanical difference requiring PCB or enclosure redesign. This part is included for reference in applications where mechanical redesign is feasible. For direct replacement without modification, DEP09P065TXLF is the appropriate choice.

Q3: What is the significance of the current rating difference between L717DEF09P (7.5A) and 172-009-102R031 (5A)?

A: Current rating defines the maximum continuous current each contact can safely carry. The L717DEF09P supports 7.5A per contact, while 172-009-102R031 supports only 5A per contact. If the application requires current levels between 5A and 7.5A, the 172-009-102R031 cannot be used. The DEP09P065TXLF maintains the 7.5A rating, ensuring full compatibility.

Q4: Does the operating temperature range difference affect substitution suitability?

A: Yes. The L717DEF09P operates from -55°C to 125°C. The 172-009-102R031 operates from -50°C to 100°C. If the application requires operation below -50°C or above 100°C, the 172-009-102R031 is unsuitable. The DEP09P065TXLF matches the full temperature range of the main part.

Q5: What does "obsolete" status mean for 172-009-102R031?

A: Obsolete status indicates the manufacturer has discontinued production. While 3677 pieces are currently in inventory, future availability cannot be guaranteed. For new designs or long-term production requirements, active status parts (L717DEF09P or DEP09P065TXLF) are recommended.

Q6: Are all three connectors RoHS compliant?

A: Yes. L717DEF09P and DEP09P065TXLF are RoHS Compliant. The 172-009-102R031 is ROHS3 Compliant. Both compliance levels meet current regulatory requirements for lead-free and restricted substance elimination.

Q7: How do contact finish specifications compare?

A: L717DEF09P has 8.00µin (0.203µm) gold plating. DEP09P065TXLF has 30.0µin (0.76µm) gold plating with GXT™ enhancement, providing superior corrosion resistance and contact longevity. The 172-009-102R031 has flash gold plating, the thinnest specification, suitable for lower-stress applications. For high-reliability applications, DEP09P065TXLF is preferred.

Q8: Can packaging differences (Bag, Tray, Bulk) affect connector performance?

A: No. Packaging is a logistics and handling specification only. It does not affect electrical performance, mechanical fit, or functional compatibility. Selection between bag, tray, or bulk packaging depends on inventory management and assembly process requirements, not technical compatibility.
