L17TF0910115 D-Sub 9-Position Plug Connector Equivalent & Substitute Parts

Part Overview

The L17TF0910115 is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products). This through-hole mounted connector features male pins with press-fit termination, designed for signal applications requiring robust mechanical and electrical performance. The connector is currently in active product status with 865 pieces available in stock.

Substitute parts are identified when equivalent D-Sub 9-position plug connectors meet the core electrical and mechanical parameters: 9-position configuration, 2-row layout, shell size 1 (DE, E), through-hole mounting, press-fit termination, and compatible operating temperature range. Alternative sources become necessary for supply chain continuity, inventory management, or when specific manufacturing certifications are required.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The D09P91C4GV00LF and D09P91C6GV00LF connectors from Amphenol ICC (FCI) are functionally equivalent to the L17TF0910115. Both maintain active product status, RoHS compliance, and identical core mechanical and electrical specifications. These parts feature higher current ratings (5A per contact versus 3A) and phosphor bronze contacts with gold finish, providing enhanced performance margins. The Delta D series designation indicates compatibility with standard D-Sub mating interfaces. Both are available in tray packaging with substantial inventory levels.

Secondary Substitute (Obsolete Status):

The 09661646716 from HARTING meets all core substitution criteria but carries obsolete product status. This part features the highest current rating (6.5A) and ROHS3 compliance. Selection of this part should be limited to applications where long-term supply is not critical or where existing inventory must be consumed. The bulk packaging format differs from the main part's tray packaging.

Selection Basis:

For new designs: Select D09P91C4GV00LF or D09P91C6GV00LF to ensure long-term availability and active manufacturer support.
For existing designs: L17TF0910115 remains the primary choice with active status and established supply chain.
For inventory management: D09P91C4GV00LF and D09P91C6GV00LF offer higher current capacity with equivalent mechanical compatibility.

All substitute parts comply with UL94 V-0 flammability requirements, operate across the -55°C to 125°C temperature range, and support 300V rated applications.

Frequently Asked Questions (FAQ)

Q: Can D09P91C4GV00LF and D09P91C6GV00LF be used interchangeably with L17TF0910115?

A: Yes. Both parts are mechanically and electrically compatible. They share identical 9-position, 2-row D-Sub plug configuration, shell size 1 (DE, E), through-hole mounting, and press-fit termination. Operating temperature ranges, voltage ratings, and flammability classifications are identical. The primary differences are contact material (phosphor bronze versus brass) and current rating (5A versus 3A per contact).

Q: What is the difference between the two Amphenol ICC (FCI) substitutes?

A: D09P91C4GV00LF and D09P91C6GV00LF differ only in contact finish thickness. D09P91C4GV00LF specifies flash gold plating, while D09P91C6GV00LF specifies 30.0µin (0.76µm) gold plating. Both are functionally equivalent for standard signal applications. The thicker plating on D09P91C6GV00LF may provide extended contact life in high-cycle mating applications.

Q: Why is 09661646716 marked as obsolete?

A: The HARTING 09661646716 is classified as obsolete by the manufacturer. While it meets all core electrical and mechanical substitution criteria, new designs should not incorporate this part. Existing inventory may be used for legacy system maintenance or repair applications where supply continuity is not required.

Q: Are there packaging differences between substitute parts?

A: Yes. L17TF0910115 and both Amphenol ICC (FCI) substitutes are supplied in tray packaging. The HARTING 09661646716 is supplied in bulk packaging. Tray packaging is standard for automated assembly processes, while bulk packaging is suitable for manual assembly or inventory consolidation.

Q: Can I use a substitute part with higher current rating in place of the L17TF0910115?

A: Yes. All substitute parts have equal or higher current ratings (5A to 6.5A per contact) compared to the main part (3A). Higher current ratings provide additional performance margin and do not create compatibility issues. The connector will function correctly in applications designed for 3A operation.

Q: What compliance certifications apply to all parts?

A: All parts meet UL94 V-0 material flammability requirements. L17TF0910115 and both Amphenol ICC (FCI) substitutes are RoHS Compliant. The HARTING 09661646716 is ROHS3 Compliant. All parts are rated for -55°C to 125°C operating temperature and 300V voltage applications.

Q: Are the flange features interchangeable?

A: The flange features differ between parts. L17TF0910115 and the Amphenol ICC (FCI) substitutes feature mating-side female screwlock fastening (M3 or 4-40). The HARTING 09661646716 features housing/shell 4-40 fastening. These design variations do not affect electrical or mechanical compatibility with standard D-Sub receptacles, but mounting hardware specifications must be verified for the specific application.
