9 Position D-Sub Receptacle Connector 5747090-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5747090-2 is a 9 Position D-Sub Receptacle connector featuring female sockets in a vertical press-fit configuration. This connector belongs to the AMPLIMITE HD-20 series and is classified as an active product with full availability. The connector utilizes a DE/E shell size (Size 1) with through-hole mounting and is designed for signal-level applications. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives from different manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5747090-2 connector is permissible when the following core parameters remain constant across all candidate parts:

Critical Matching Parameters:

• Connector Style: D-Sub
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 9
• Number of Rows: 2
• Shell Size, Connector Layout: 1 (DE, E)
• Mounting Type: Through Hole
• Termination: Press-Fit
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0

Allowable Variations: Substitute parts may differ in the following parameters while maintaining functional compatibility:

• Manufacturer and series designation
• Packaging format (Bulk vs. Tray)
• Shell material finish composition (Tin Plated vs. Tin-Nickel Plated)
• Contact finish thickness specifications
• Dielectric material composition
• Operating temperature upper limit (provided minimum -55°C is maintained)
• Current rating per contact (provided application requirements are satisfied)
• Voltage rating (provided application requirements are satisfied)
• Flange feature design (4-40 threaded vs. Unthreaded)
• Contact material composition (Copper Alloy vs. Phosphor Bronze)

The three substitute parts listed—D09S90C4PA00LF, D09S91C6PX00LF, and L17TF0902100—satisfy all critical matching parameters and are therefore electrically and mechanically compatible with the primary part 5747090-2.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and full RoHS compliance, ensuring regulatory alignment with the primary part 5747090-2. The selection among substitute parts depends on specific application requirements and design constraints:

D09S91C6PX00LF provides the closest mechanical alignment to the primary part, featuring identical 4-40 threaded flange configuration. This part is manufactured by Amphenol ICC (FCI) within the Delta D series and offers 5A per contact current rating with 300V voltage rating. The operating temperature range extends to 125°C, exceeding the primary part specification. REACH status is unaffected, which may be advantageous in certain supply chain contexts. This part is supplied in Tray packaging.

D09S90C4PA00LF offers an alternative from the same manufacturer and series (Delta D) with identical electrical specifications (5A per contact, 300V). The primary distinction is the unthreaded flange feature, which requires evaluation against mounting requirements. This part is also supplied in Tray packaging and maintains REACH affected status.

L17TF0902100 represents an alternative from Amphenol ICC Commercial Products within the TF series. This part features unthreaded flange configuration and a reduced current rating of 3A per contact. The operating temperature range matches the extended specification at 125°C. This part is supplied in Tray packaging and is suitable for applications where the 3A current rating satisfies design requirements.

Selection should prioritize matching the flange feature (4-40 threaded vs. unthreaded) to the existing PCB or mounting structure, and confirming that the current rating of the selected substitute meets or exceeds application demands.

Frequently Asked Questions (FAQ)

Q: Can D09S91C6PX00LF directly replace 5747090-2 in existing designs?

A: Yes. D09S91C6PX00LF maintains all critical parameters including 9-position configuration, DE/E shell size, through-hole mounting, press-fit termination, and UL94 V-0 flammability rating. The 4-40 threaded flange matches the primary part, enabling direct mechanical substitution. The extended operating temperature range (125°C vs. 105°C) and higher current rating (5A vs. unspecified) provide additional design margin.

Q: What is the difference between the flange features on these connectors?

A: The primary part 5747090-2 and substitute D09S91C6PX00LF feature 4-40 threaded flanges, which allow screw-based mechanical fastening to the PCB or enclosure. Substitutes D09S90C4PA00LF and L17TF0902100 feature unthreaded flanges, which require alternative mounting methods such as snap-fit or adhesive attachment. Flange selection must align with the existing mechanical design.

Q: Are there current rating differences that affect substitution?

A: The primary part 5747090-2 does not specify a current rating. Substitutes D09S91C6PX00LF and D09S90C4PA00LF are rated at 5A per contact, while L17TF0902100 is rated at 3A per contact. For applications requiring current levels above 3A per contact, L17TF0902100 is not suitable. For applications requiring current levels between 3A and 5A, all three substitutes are acceptable.

Q: What packaging differences exist among these parts?

A: The primary part 5747090-2 is supplied in Bulk packaging. All three substitutes are supplied in Tray packaging. Tray packaging typically provides better component protection during storage and handling but may require different receiving and inventory procedures. Bulk packaging is generally used for high-volume applications with integrated assembly processes.

Q: Do all substitutes meet the same environmental compliance standards?

A: All parts are RoHS compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating. The primary part is ROHS3 compliant and REACH affected. Substitutes D09S90C4PA00LF and L17TF0902100 are REACH affected, while D09S91C6PX00LF is REACH unaffected. For applications subject to REACH restrictions, D09S91C6PX00LF may provide supply chain advantages.

Q: Can the operating temperature range differences affect part selection?

A: The primary part operates from -55°C to 105°C. All three substitutes extend the upper limit to 125°C. This difference is not a limiting factor for substitution; the extended range of substitute parts provides additional thermal margin. Selection should be based on actual application temperature requirements rather than specification differences.

Q: What contact material differences exist, and do they affect compatibility?

A: The primary part uses Copper Alloy contacts, while all three substitutes use Phosphor Bronze contacts. Both materials are suitable for signal-level D-Sub applications and maintain gold plating for corrosion resistance and electrical performance. Material composition differences do not prevent substitution in standard signal applications.
