L17TF0901112 D-Sub Receptacle 9-Position Equivalent & Substitute Parts

Part Overview

The L17TF0901112 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets with press-fit termination, through-hole mounting, and a mating-side female screwlock flange. The part is currently in active product status with 780 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits the use of compatible connector types within the same D-Sub family. Substitute parts must maintain electrical and mechanical compatibility with the original design specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub connectors is determined by strict compatibility across the following parameters:

Critical Compatibility Parameters:

• Connector Style: D-Sub (all candidates must be D-Sub)
• Shell Size and Connector Layout: 1 (DE, E) (physical mating interface)
• Number of Positions: 9 (pin count)
• Number of Rows: 2 (pin arrangement)
• Mounting Type: Through Hole (PCB interface)
• Termination: Press-Fit (connection method)
• Operating Temperature Range: -55°C ~ 125°C (environmental tolerance)
• Voltage Rating: 300V (electrical safety)
• Material Flammability Rating: UL94 V-0 (safety compliance)

Note on Connector Type Substitution: The provided substitute parts include both receptacle (female socket) and plug (male pin) connector types. While these are mechanically and electrically compatible within a mated pair assembly, direct one-to-one substitution of a receptacle with a plug requires design-level consideration of the overall connector interface architecture.

Parameter Comparison

Engineering Selection Recommendations

D09P91C4GV00LF and D09P91C6GV00LF (Amphenol ICC FCI Series)

Both D09P91C4GV00LF and D09P91C6GV00LF are active-status plug connectors from Amphenol ICC (FCI division). These parts meet all critical compatibility parameters with the L17TF0901112 receptacle, including shell size, position count, mounting type, termination method, operating temperature range, voltage rating, and flammability compliance. Both parts are RoHS Compliant with MSL 1 rating. The primary difference between these two variants is contact finish thickness (Flash versus 30.0µin). Both support higher current ratings (5A per contact) than the main part (3A), providing design margin. These parts are suitable for applications requiring plug-side connectivity within the same D-Sub assembly.

09661646716 (HARTING)

The HARTING 09661646716 is a 9-position D-Sub plug connector with through-hole press-fit termination and matching shell size. This part meets the critical compatibility parameters for shell size, position count, mounting type, and termination. However, this part carries an obsolete product status, indicating it is no longer in active production or support. The contact finish and voltage rating are not specified in the provided data. ROHS3 compliance is documented. This part is not recommended for new designs due to its obsolete status, though it may be considered only for legacy system maintenance where existing inventory is available.

Recommendation Summary:

For new designs or active production requiring D-Sub 9-position plug connectivity, select either D09P91C4GV00LF or D09P91C6GV00LF. Both are active-status Amphenol ICC products with full electrical and mechanical compatibility. The HARTING 09661646716 is not recommended for new applications due to obsolete product status.

Frequently Asked Questions (FAQ)

Q: Can D09P91C4GV00LF or D09P91C6GV00LF be used as direct replacements for L17TF0901112?

A: These parts are plug (male pin) connectors, while L17TF0901112 is a receptacle (female socket) connector. They are not direct one-to-one replacements. However, they are mechanically and electrically compatible for mating with the L17TF0901112 receptacle in a complete connector assembly. Selection depends on whether your application requires a receptacle or plug connector.

Q: What is the difference between D09P91C4GV00LF and D09P91C6GV00LF?

A: Both parts are functionally equivalent 9-position D-Sub plugs with identical electrical and mechanical specifications. The primary difference is contact finish thickness: D09P91C4GV00LF has flash gold plating, while D09P91C6GV00LF has 30.0µin (0.76µm) gold plating. Both meet the 300V voltage rating and -55°C to 125°C operating temperature range.

Q: Why is 09661646716 listed as obsolete?

A: The HARTING 09661646716 carries an obsolete product status, indicating it is no longer manufactured or supported by the supplier. While the part may still be available from inventory, it is not recommended for new designs. Amphenol ICC FCI alternatives (D09P91C4GV00LF or D09P91C6GV00LF) are preferred for active production.

Q: Are all substitute parts RoHS compliant?

A: D09P91C4GV00LF and D09P91C6GV00LF are RoHS Compliant. The HARTING 09661646716 is ROHS3 Compliant. All three parts meet RoHS requirements, though the specific RoHS version differs.

Q: What is the current rating difference between the main part and substitutes?

A: The L17TF0901112 receptacle is rated for 3A. The D09P91C4GV00LF and D09P91C6GV00LF plugs are rated for 5A per contact. The HARTING 09661646716 is rated for 6.5A. Higher current ratings in substitute parts provide design margin and do not prevent substitution in applications requiring 3A or less.

Q: Can I use these connectors in applications outside the -55°C to 125°C temperature range?

A: No. All listed parts, including the main part and substitutes, are specified for operation within -55°C to 125°C. Use outside this range is not supported by the provided specifications.

Q: What packaging is available for each part?

A: L17TF0901112 is supplied in Tray packaging. D09P91C4GV00LF and D09P91C6GV00LF are supplied in Tray packaging. HARTING 09661646716 is supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.
