D09S91C6GL00 9-Position D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The D09S91C6GL00 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the Delta D series. This connector features female sockets, through-hole mounting, and press-fit termination with a 5A current rating per contact. The part is currently obsolete, with 937 units available in new original stock. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for ongoing system support and new designs requiring compatible D-Sub receptacle functionality.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Connector Type & Position Count: All substitutes must be 9-position D-Sub receptacles with female sockets
Shell Size & Layout: Shell size 1 (DE, E) is mandatory for mechanical compatibility
Mounting & Termination: Through-hole mounting with press-fit termination required
Electrical Ratings: Voltage rating of 300V and operating temperature range of -55°C ~ 125°C must be maintained
Contact Material & Finish: Phosphor bronze contacts with gold finish ensure signal integrity
Flange Configuration: Substitutes are grouped by flange type (unthreaded, M3 threaded, 4-40 threaded, or screwlock variants)

The primary distinction between substitutes is the current rating (5A vs. 3A) and shell finish (tin plated vs. tin-nickel plated). Current rating reduction from 5A to 3A is acceptable only when system design does not require the higher amperage per contact. RoHS compliance status differs between the obsolete original and active substitutes.

Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility)

D09S91C6GL00LF is the direct successor to D09S91C6GL00 within the Delta D series. Both maintain 5A current rating, M3 flange configuration, and identical electrical specifications. The primary difference is shell finish (tin-nickel vs. tin plated) and RoHS compliance status. This part is active and recommended for new designs requiring the original 5A rating with modern compliance certifications.

Primary Substitutes (Amphenol TF Series)

L17TF0900104 and L17TF0900114 are functionally equivalent alternatives from the active Amphenol TF series. Both feature M3 flange configuration matching the original part's mounting interface. The trade-off is reduced current rating (3A vs. 5A), which is acceptable for applications not requiring the full 5A per-contact capacity. These parts are RoHS compliant and offer superior long-term availability.

Alternative Flange Configurations (TF Series)

L17TF0900100, L17TF0900102, L17TF0900105, L17TF0900111, and L17TF0900115 provide substitution options with different flange types (unthreaded, 4-40 threaded, or M3 screwlock). Selection depends on mechanical mounting requirements. All maintain 9-position, 300V, -55°C to 125°C specifications with 3A current rating and RoHS compliance.

Cross-Manufacturer Option

2-338210-2 (TE Connectivity AMPLIMITE HDP-20 series) is a manufacturer-recommended alternative. Electrical and mechanical specifications align with the original part. This option provides supply chain diversification and is suitable when multi-source qualification is required.

Dielectric Material Consideration

The original D09S91C6GL00 uses PBT dielectric material. Amphenol TF series substitutes employ thermoplastic glass-filled dielectric. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range. Material substitution does not affect electrical performance for standard D-Sub applications.

Frequently Asked Questions (FAQ)

Q: Can L17TF0900104 directly replace D09S91C6GL00 in existing designs?

A: Mechanical and electrical compatibility is confirmed for shell size 1 (DE, E), 9-position receptacle, through-hole mounting, and press-fit termination. The M3 flange configuration matches the original part. Current rating reduction from 5A to 3A per contact is the primary design consideration. If circuit design operates within 3A per-contact limits, substitution is valid. If higher current capacity is required, D09S91C6GL00LF maintains the 5A rating.

Q: What is the difference between tin-plated and tin-nickel plated shell finishes?

A: Both finishes provide corrosion resistance and are suitable for standard industrial environments. Tin-nickel plating offers enhanced durability in harsh or marine environments. For typical applications, either finish is acceptable. The choice depends on environmental exposure and long-term reliability requirements.

Q: Are the TF series parts (L17TF09 base number) fully compatible with Delta D series mounting?

A: Yes. Both series use identical shell size 1 (DE, E) geometry and through-hole press-fit termination. Mechanical interchangeability is confirmed. Flange type (M3, unthreaded, 4-40, or screwlock) must match the application's mounting interface.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition (lead-free solder, restricted substances) and does not alter electrical characteristics, current rating, voltage rating, or operating temperature range. All RoHS-compliant substitutes maintain identical electrical performance.

Q: What is the significance of contact finish thickness (30.0µin vs. Flash)?

A: Contact finish thickness affects durability and mating cycle life. 30.0µin (0.76µm) provides thicker gold plating for extended contact life and superior wear resistance. Flash plating (minimal thickness) is suitable for applications with limited mating cycles. For high-cycle applications, parts with 30.0µin finish are preferred.

Q: Can I use L17TF0902100 as a substitute?

A: L17TF0902100 is compatible with all core electrical and mechanical parameters. It features unthreaded flange configuration (vs. M3 on the original). Substitution is valid only if the application does not require threaded flange mounting. Verify mechanical mounting interface before selection.

Q: Is 2-338210-2 from TE Connectivity a viable long-term alternative?

A: Yes. TE Connectivity AMPLIMITE HDP-20 series part 2-338210-2 meets all electrical and mechanical requirements. Cross-manufacturer qualification provides supply chain resilience. Verify connector mating compatibility with existing plug connectors before implementation.
