D-Sub 9 Position Receptacle Connector D09S91C4GL00LF Equivalent & Substitute Parts

Part Overview

The D09S91C4GL00LF is a 9 position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole mounted connector features female sockets with press-fit termination, designed for signal applications requiring robust electrical connectivity. The part is currently active in production with 1029 units in stock. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or when specific performance parameters align with application needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 9 position receptacle connectors is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Shell size and layout: 1 (DE, E)
• Mounting type: Through Hole
• Termination method: Press-Fit
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold
• Flammability rating: UL94 V-0

Secondary Compatibility Considerations:

• Operating temperature range (minimum -55°C, maximum ≥105°C)
• Current and voltage ratings (equal or greater than application requirements)
• RoHS and regulatory compliance status

The three substitute parts identified (5747090-2, 747089-2, and L17TF0902100) meet all primary compatibility criteria. Variations in flange feature design (M3 threaded, 4-40 threaded, or unthreaded), contact material composition (Phosphor Bronze vs. Copper Alloy), and dielectric material specifications do not prevent functional substitution when electrical and mechanical envelope requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

5747090-2 (TE Connectivity AMPLIMITE HD-20): This substitute is recommended for applications where extended inventory availability is required. The part maintains all primary mechanical and electrical compatibility parameters. Operating temperature range is limited to -55°C ~ 105°C compared to the main part's -55°C ~ 125°C specification; applications requiring operation above 105°C must use the main part or L17TF0902100. ROHS3 compliance status provides enhanced regulatory coverage for current and future environmental directives.

747089-2 (TE Connectivity AMPLIMITE HD-20): This substitute provides functional equivalence with unthreaded flange design. Limited inventory (746 units) restricts its use to applications where immediate availability is not critical. RoHS status is not applicable; verify compliance requirements for your application before selection. Operating temperature maximum of 105°C applies the same constraint as 5747090-2.

L17TF0902100 (Amphenol ICC TF Series): This substitute maintains full operating temperature range compatibility (-55°C ~ 125°C) and RoHS compliance status matching the main part. Current rating is specified at 3A, which is lower than the main part's 5A rating; applications requiring sustained current above 3A must use the main part or verify load profile compatibility. Contact finish thickness is explicitly specified at 30.0µin (0.76µm), providing defined wear characteristics for high-cycle mating applications.

All substitute parts are active products with confirmed inventory availability and maintain the required UL94 V-0 flammability rating and gold contact finish for signal-level applications.

Frequently Asked Questions (FAQ)

Q: Can 5747090-2 be used in applications operating above 105°C? A: No. The 5747090-2 operating temperature range is -55°C ~ 105°C. Applications requiring operation above 105°C must use D09S91C4GL00LF or L17TF0902100, both rated to 125°C.

Q: What is the difference between the flange features (M3, 4-40, and Unthreaded)? A: Flange features define the mounting interface. M3 uses metric threads, 4-40 uses imperial threads, and unthreaded flanges rely on friction or adhesive mounting. Selection depends on PCB design and mechanical assembly requirements. All three designs maintain electrical compatibility.

Q: Is 747089-2 suitable for new designs requiring RoHS compliance? A: The 747089-2 RoHS status is listed as "Not applicable." Verify with TE Connectivity whether this part meets your specific RoHS compliance requirements before design implementation.

Q: Can L17TF0902100 be used in applications requiring 5A current? A: The L17TF0902100 is rated for 3A maximum current. Applications requiring sustained 5A operation must use D09S91C4GL00LF or verify that actual load current does not exceed 3A in your application profile.

Q: Are all substitute parts compatible with the same mating connectors? A: Yes. All parts are 9 position D-Sub receptacles with shell size 1 (DE, E) and through-hole mounting. They are mechanically and electrically compatible with standard D-Sub 9 position plugs and cable assemblies designed for this connector family.

Q: What is the significance of contact finish thickness specifications? A: Contact finish thickness affects wear resistance and service life in high-cycle mating applications. L17TF0902100 specifies 30.0µin (0.76µm) thickness; D09S91C4GL00LF and 747089-2 specify "Flash" thickness (typically <0.5µm). For applications exceeding 500 mating cycles, verify finish thickness requirements with your connector supplier.

Q: Can these parts be used interchangeably in existing assemblies? A: Mechanical and electrical interchangeability is confirmed for all four parts. However, verify flange design compatibility with existing PCB mounting holes and mechanical fixtures before substitution in production assemblies.
