• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Termination method: Solder Cup
• Contact type: Signal
• Shell material: Steel with tin plating
• Contact material: Brass or Copper Alloy
• Flammability rating: UL94 V-0

Secondary Compatibility Criteria:

• Current rating: Minimum 5A (main part rated 7.5A)
• Voltage rating: Minimum 300V
• Operating temperature range: Must encompass or overlap with -55°C ~ 155°C
• Contact finish: Gold plating

The substitute parts listed below satisfy these criteria within acceptable engineering tolerances for D-Sub connector applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: DEP09P065TXLF

The DEP09P065TXLF is the preferred substitute for the L717DFEG09P when supply of the primary part is constrained. Both parts are manufactured by Amphenol ICC and maintain Active product status. The DEP09P065TXLF provides equivalent current rating (7.5A per contact), superior voltage rating (1000V versus 300V), and enhanced contact finish thickness (30.0µin GXT™ plating versus 20.0µin standard gold). The primary difference is mounting configuration: DEP09P065TXLF is Free Hanging (In-Line) whereas L717DFEG09P is Panel Mount. This difference requires mechanical redesign of the mounting interface and is not a direct drop-in replacement. Both parts are RoHS Compliant and suitable for the same electrical applications.

Secondary Substitute: 172-009-102R031

The 172-009-102R031 manufactured by NorComp Inc. maintains compatibility with the core D-Sub 9-position, 2-row, shell size 1 (DE, E) specification. This part is Panel Mount, matching the L717DFEG09P mounting configuration. However, the 172-009-102R031 carries Obsolete product status and exhibits reduced current rating (5A versus 7.5A) and narrower operating temperature range (-50°C ~ 100°C versus -55°C ~ 155°C). The 172-009-102R031 is ROHS3 Compliant and suitable for legacy system maintenance or applications with reduced thermal and current requirements. Flange feature differs (Mating Side 4-40 versus Cable Side M3), requiring mechanical verification.

Selection Criteria:

• For direct mechanical replacement with equivalent electrical performance: DEP09P065TXLF requires mounting interface redesign but provides superior electrical ratings and Active product status.
• For panel mount applications with reduced electrical requirements: 172-009-102R031 maintains panel mount configuration but is Obsolete and exhibits lower current and temperature ratings.
• For new designs: Maintain L717DFEG09P as primary selection due to Active status and full temperature range support.

Frequently Asked Questions (FAQ)

Q1: Can DEP09P065TXLF be used as a direct drop-in replacement for L717DFEG09P?

A: DEP09P065TXLF is electrically compatible but not a mechanical drop-in replacement. The primary difference is mounting type: DEP09P065TXLF is Free Hanging (In-Line) while L717DFEG09P is Panel Mount. The connector interface (9-position, 2-row, shell size 1 DE/E) and termination method (solder cup) are identical. Mechanical redesign of the mounting interface is required.

Q2: What is the significance of the flange feature difference between L717DFEG09P and 172-009-102R031?

A: L717DFEG09P features Cable Side flange with M3 mounting, while 172-009-102R031 features Mating Side flange with 4-40 mounting. These differences affect the mechanical mounting interface and require verification against the application's mechanical design. The electrical connector interface remains compatible.

Q3: Why is 172-009-102R031 listed as Obsolete?

A: Obsolete product status indicates that NorComp Inc. has discontinued manufacturing and support for this part. While existing inventory may be available (3677 Pcs reported), long-term supply cannot be guaranteed. This part is suitable only for maintenance of existing systems or applications with extended procurement timelines.

Q4: What is the impact of current rating differences between the three parts?

A: L717DFEG09P and DEP09P065TXLF both support 7.5A current rating, suitable for high-current signal applications. The 172-009-102R031 is rated for 5A, limiting its use to lower-current applications. Current rating selection must match the application's maximum continuous current requirement.

Q5: How do operating temperature ranges affect part selection?

A: L717DFEG09P supports -55°C ~ 155°C, the widest range among the three parts. DEP09P065TXLF supports -55°C ~ 125°C, and 172-009-102R031 supports -50°C ~ 100°C. Applications requiring operation below -50°C or above 125°C must use L717DFEG09P. Applications with narrower temperature requirements may use substitute parts.

Q6: Are all three parts RoHS compliant?

A: Yes. L717DFEG09P and DEP09P065TXLF are RoHS Compliant. The 172-009-102R031 is ROHS3 Compliant. All three parts meet current RoHS requirements for new applications.

Q7: What is the difference between gold contact finish thicknesses?

A: L717DFEG09P has 20.0µin (0.51µm) gold plating, DEP09P065TXLF has 30.0µin (0.76µm) GXT™ gold plating, and 172-009-102R031 has flash gold plating. Thicker plating (DEP09P065TXLF) provides enhanced corrosion resistance and contact durability. Flash plating (172-009-102R031) provides basic corrosion protection with minimal thickness.

Q8: Can packaging differences affect part selection?

A: Packaging differences (Bag, Bulk, Tray) do not affect electrical or mechanical compatibility. Packaging selection depends on procurement volume, inventory management, and handling requirements. All three parts are available in their respective packaging formats.
