Engineering Selection Recommendations

L17TF0900102 (Primary Selection) Select this part when through-hole mounting with mating-side female screwlock (4-40) flange is required. The tin-plated steel shell and thermoplastic glass-filled dielectric provide standard environmental protection. This part maintains active production status with 1061 units in stock.

191-009-223R001 (Panel Mount Alternative) Select this NorComp part when panel-mount configuration is required instead of through-hole mounting. The higher current rating of 5A and shielded design provide enhanced performance characteristics. ROHS3 compliance and nickel-plated steel shell offer alternative corrosion resistance. Use when panel integration is the primary mechanical constraint. 2047 units in stock.

D09S91C4PL00LF (Delta D Series, M3 Flange) Select this Amphenol ICC (FCI) Delta D series part for through-hole mounting with M3 housing/shell flange configuration. The 5A per contact rating and tin-nickel plated steel shell provide enhanced current capacity and corrosion resistance compared to the main part. Polybutylene terephthalate (PBT) dielectric offers alternative material properties. 1156 units in stock.

D09S91C4PX00LF (Delta D Series, 4-40 Flange) Select this part when through-hole mounting with 4-40 housing/shell flange is required, matching the main part's flange specification. The Delta D series construction with 5A per contact rating and tin-nickel plated finish provides enhanced performance. PBT dielectric material is suitable for applications requiring different thermal or mechanical properties. 3667 units in stock.

D09S91C6PX00LF (Delta D Series, Enhanced Gold Finish) Select this part for applications requiring specified gold contact finish thickness of 30.0µin (0.76µm) rather than flash plating. Through-hole mounting with 4-40 flange matches the main part configuration. The 5A per contact rating and tin-nickel plated steel shell provide performance enhancement. 1245 units in stock.

All substitute parts maintain UL94 V-0 flammability rating, -55°C to 125°C operating temperature range, and RoHS compliance, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can D09S91C4PX00LF be used as a direct replacement for L17TF0900102?

A: Yes. Both parts share identical connector style (D-Sub), type (receptacle, female sockets), position count (9), row configuration (2), shell size (1 DE/E), mounting type (through-hole), termination method (press-fit), voltage rating (300V), operating temperature range (-55°C to 125°C), contact material (phosphor bronze), and flammability rating (UL94 V-0). The D09S91C4PX00LF provides higher current capacity (5A per contact versus 3A) and alternative shell finish (tin-nickel versus tin), both of which are compatible with the original application.

Q: What is the key difference between the main part L17TF0900102 and the Delta D series substitutes?

A: The primary differences are manufacturer (Amphenol ICC Commercial Products versus Amphenol ICC FCI), series designation (TF versus Delta D), shell finish (tin plated versus tin-nickel plated), dielectric material (thermoplastic glass-filled versus polybutylene terephthalate), and current rating (3A versus 5A per contact). All other critical parameters including connector configuration, mounting type, voltage rating, and operating temperature remain identical.

Q: When should 191-009-223R001 be selected instead of through-hole alternatives?

A: Select the NorComp 191-009-223R001 when the application requires panel-mount configuration rather than through-hole mounting. This part features housing/shell flange design for panel integration and includes shielding for enhanced electromagnetic compatibility. The 5A current rating and nickel-plated steel shell provide additional performance benefits for panel-mounted applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part L17TF0900102 is RoHS compliant. Substitute parts 191-009-223R001, D09S91C4PL00LF, D09S91C4PX00LF, and D09S91C6PX00LF are either RoHS compliant or ROHS3 compliant, ensuring regulatory compatibility across all options.

Q: What is the difference between D09S91C4PX00LF and D09S91C6PX00LF?

A: Both parts are identical except for contact finish thickness. D09S91C4PX00LF has flash gold plating, while D09S91C6PX00LF specifies 30.0µin (0.76µm) gold contact finish thickness. Select D09S91C6PX00LF when applications require defined gold plating thickness for wear resistance or contact reliability specifications.

Q: Can the higher current rating of substitute parts affect circuit design?

A: The substitute parts with 5A per contact rating are compatible with applications designed for the 3A rating of L17TF0900102. Higher current capacity does not negatively impact lower-current applications. However, applications requiring the full 5A capacity should use substitute parts rather than the main part.

Q: What packaging format is used for all parts?

A: All parts are supplied in tray packaging, maintaining consistent handling and storage requirements across the main part and all substitutes.

Q: Are there differences in dielectric material between parts?

A: Yes. L17TF0900102 uses thermoplastic glass-filled dielectric, while D09S91C4PL00LF, D09S91C4PX00LF, and D09S91C6PX00LF use polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range. The NorComp 191-009-223R001 uses polyamide (PA6T) nylon 6T dielectric. Material selection depends on specific application thermal and mechanical requirements.

Q: What is the significance of the flange feature differences?

A: L17TF0900102 features mating-side female screwlock (4-40) flange. D09S91C4PL00LF features M3 housing/shell flange, while D09S91C4PX00LF and D09S91C6PX00LF feature 4-40 housing/shell flange. The 191-009-223R001 features unthreaded housing/shell flange for panel mounting. Flange selection depends on mechanical mounting requirements and mating connector specifications.
