Part Overview
The L177DFEG09SOL2RM5 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This panel-mount, through-hole solder connector features female sockets in a 2-row configuration with shell size 1 (DE, E) layout. The connector is actively produced and stocked with 873 units in inventory.
D-Sub receptacle connectors serve as mating interfaces for signal transmission in industrial, telecommunications, and computing applications. Equivalent and substitute parts become necessary when the primary part experiences supply constraints, when alternative packaging formats are required, or when design modifications necessitate different flange configurations or material specifications.

Substitute Part Grouping Explanation
Substitution of D-Sub receptacle connectors is determined by strict equivalence across the following critical parameters:
Mandatory Equivalence Parameters:
- Connector type (receptacle with female sockets)
- Number of positions (9)
- Number of rows (2)
- Shell size and layout (1 / DE, E)
- Termination method (solder)
- Material flammability rating (UL94 V-0)
- Moisture sensitivity level (MSL 1 / Unlimited)
Functional Compatibility Parameters:
- Current rating (minimum 7.5A required)
- Voltage rating (minimum 300V required)
- Operating temperature range (must encompass -55°C to 125°C)
- Contact material (copper alloy or phosphor bronze)
Substitution Constraints: Mounting type variations (panel mount vs. through-hole only) and flange feature differences (board-side vs. mating-side configurations) are permitted when the substitute part maintains electrical and mechanical interface compatibility. Contact finish specifications and shell material finishes may vary provided they maintain equivalent electrical performance and environmental protection.
The substitute parts listed below meet the mandatory equivalence parameters. Variations in mounting configuration, flange design, and material composition are noted to enable informed selection based on specific application requirements.

Engineering Selection Recommendations
Primary Substitute: 09641127235 (HARTING)
The HARTING 09641127235 provides the closest electrical and mechanical equivalence to the L177DFEG09SOL2RM5. This part maintains identical current rating (7.5A), matching position count, row configuration, and shell size. Both connectors feature board-side flange mounting with board lock functionality and UL94 V-0 flammability compliance. The primary difference is the reduced voltage rating (100V vs. 300V) and narrower operating temperature minimum (-20°C vs. -55°C). This substitute is suitable for applications where the 300V and -55°C specifications are not required. Inventory availability is high at 1,362 units.
Secondary Substitute: 09661556513 (HARTING)
The HARTING 09661556513 maintains full operating temperature equivalence (-55°C to 125°C) and includes gold contact finish matching the primary part. Current rating is reduced to 6.5A, and voltage rating is not specified. This connector features mating-side female screwlock flange configuration rather than board-side mounting. This substitute is applicable when mating-side screwlock retention is preferred and current requirements do not exceed 6.5A. Inventory is substantial at 1,873 units.
Tertiary Substitute: 1-5747150-4 (TE Connectivity AMP Connectors)
The TE Connectivity 1-5747150-4 from the AMPLIMITE HD-20 series provides gold contact finish and tin-plated steel shell matching the primary part specifications. Current rating is reduced to 6A, and maximum operating temperature is limited to 105°C. Voltage rating is specified at 125V. This connector features mating-side female screwlock configuration. This substitute is suitable for applications with reduced current and temperature requirements. Inventory availability is 1,757 units.
Alternative Substitute: 191-009-213L571 (NorComp Inc.)

Frequently Asked Questions (FAQ)
Q: Can the HARTING 09641127235 be used as a direct replacement for the L177DFEG09SOL2RM5?
A: The HARTING 09641127235 is electrically and mechanically compatible for applications where the voltage requirement does not exceed 100V and the minimum operating temperature does not go below -20°C. Both connectors share identical position count (9), row configuration (2), shell size (1 / DE, E), current rating (7.5A), and flammability compliance (UL94 V-0). The primary limitation is the reduced voltage and temperature specifications.
Q: What is the difference between board-side and mating-side flange configurations?
A: Board-side flange mounting (M3 or 4-40 threaded) secures the connector to the circuit board or panel from the component side. Mating-side female screwlock configuration secures the connector through the mating connector's screwlock mechanism. The choice depends on the mechanical assembly method and available mounting space in the application.
Q: Are all substitute parts RoHS compliant?
A: The HARTING parts (09641127235, 09661116503, 09661556513) and NorComp part (191-009-213L571) are ROHS3 compliant. The TE Connectivity 1-5747150-4 is RoHS compliant. Both compliance levels meet current regulatory requirements. Verify specific compliance requirements for your application jurisdiction.
Q: What is the significance of the current rating differences among substitute parts?
A: Current rating indicates the maximum continuous current the connector can safely carry without exceeding temperature limits. The L177DFEG09SOL2RM5 is rated for 7.5A. Substitute parts with lower ratings (6.5A, 6A, or 5A) must not be used in applications requiring higher current levels. Verify your application's current requirements before selecting a substitute.
Q: Does packaging format affect connector performance?
A: Packaging format (tray, tube, or bulk) does not affect electrical or mechanical performance. Packaging selection is based on inventory management, handling requirements, and assembly process compatibility. The L177DFEG09SOL2RM5 is supplied in tray packaging. Substitute parts are available in tube or bulk packaging, which may require process adjustments during assembly.
Q: Can I use a substitute with a lower voltage rating in a 300V application?
A: No. Voltage rating specifies the maximum voltage the connector can safely withstand without electrical breakdown or arcing. Using a connector with a lower voltage rating in a higher-voltage application creates a safety hazard and violates electrical design standards. Select a substitute with voltage rating equal to or greater than the application requirement.
Q: What does MSL 1 (Unlimited) moisture sensitivity level mean?
A: MSL 1 (Unlimited) indicates the connector has no moisture sensitivity restrictions. The part can be stored and handled under standard environmental conditions without special desiccant packaging or shelf-life limitations. All listed substitute parts share this specification with the primary part.
Q: Are the contact materials (copper alloy vs. phosphor bronze) interchangeable?
A: Both copper alloy and phosphor bronze are acceptable contact materials for D-Sub connectors. Phosphor bronze (used in TE Connectivity and NorComp parts) offers slightly different mechanical and electrical properties but maintains compatibility with standard D-Sub mating connectors. Material selection does not affect functional interchangeability.
Q: Which substitute offers the best inventory availability?
A: The NorComp 191-009-213L571 has the highest inventory at 8,799 units. The TE Connectivity 1-5747150-6 has 3,384 units, and the HARTING 09661556513 has 1,873 units. Inventory levels should be verified at the time of procurement, as availability changes continuously.
