L177SDEG09SOL2RM8 D-Sub 9-Position Receptacle Equivalent & Substitute Parts

Part Overview

The L177SDEG09SOL2RM8 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC, featuring female sockets with vertical through-hole solder termination. This connector is classified as a D-shaped connector (Shell Size 1, DE/E layout) with board-side M3 mounting and mating-side female screwlock (M3). The part is active in production status with 915 units currently in stock.

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or specific design requirements that permit parameter variation within acceptable engineering tolerances for D-Sub receptacle connectors.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The TE Connectivity AMPLIMITE HD-20 series parts (1-5747150-3, 1-5747150-4, 1-5747150-6) provide the closest functional equivalence to the L177SDEG09SOL2RM8. These parts maintain the 9-position D-Sub receptacle configuration, through-hole solder termination, and operating temperature range of -55°C to 125°C. All three variants are ROHS3 Compliant or RoHS Compliant. The primary design difference is the mating-side female screwlock (4-40) configuration versus the original M3 specification. These parts are suitable for applications where mating-side locking is acceptable and where the 6A current rating meets or exceeds system requirements.

Secondary Substitutes (Conditional Compatibility):

HARTING 09661116503 and 09661117503 maintain the full operating temperature range (-55°C to 125°C) and provide 6.5A current capacity. Both feature mating-side female screwlock (4-40) mounting. ROHS3 Compliance status is confirmed. These parts are suitable for applications where the M3 board-side mounting is not critical and where mating-side locking is acceptable.

HARTING 09641127235 provides board-side (4-40) mounting with board lock feature, matching the board-side mounting philosophy of the original part. However, the operating temperature range is limited to -20°C to 125°C, which restricts use in applications requiring full -55°C operation. This part is suitable only for applications operating above -20°C.

Voltage Rating Considerations:

The original L177SDEG09SOL2RM8 specifies 250V rating. Substitute parts from HARTING (09641127230, 09641127235) specify 100V, and TE Connectivity parts do not specify voltage rating. For applications requiring 250V isolation or operating voltage, voltage rating compatibility must be verified against actual system requirements before substitution.

RoHS Compliance:

Part 1-747150-4 is RoHS non-compliant and should not be selected for applications requiring RoHS compliance certification.

Frequently Asked Questions (FAQ)

Q: Can I substitute a HARTING 09641127235 for the L177SDEG09SOL2RM8 in all applications?

A: The 09641127235 is functionally compatible for 9-position D-Sub receptacle solder termination applications. However, two limitations apply: (1) Operating temperature range is -20°C to 125°C, restricting use in applications requiring -55°C operation; (2) Voltage rating is 100V versus the original 250V specification. Verify that your application does not require these higher specifications before substitution.

Q: What is the difference between board-side and mating-side flange features?

A: Board-side flange features mount to the printed circuit board with M3 or 4-40 threaded holes, providing mechanical retention at the connector base. Mating-side female screwlock features mount at the connector mating interface, providing retention through the mating connector's locking mechanism. Selection depends on mechanical design requirements and available mounting locations on the PCB.

Q: Are all substitute parts RoHS compliant?

A: Most substitute parts are ROHS3 Compliant or RoHS Compliant. Exception: 1-747150-4 is RoHS non-compliant. Verify RoHS compliance requirements for your application before final part selection.

Q: Can I use a substitute part with higher current rating than the original?

A: Yes. The L177SDEG09SOL2RM8 specifies 3A current rating. Substitute parts with 6A, 6.5A, or 7.5A ratings provide equal or greater current capacity and are acceptable for applications where the original 3A rating is sufficient. Higher current rating does not create compatibility issues; it provides design margin.

Q: What packaging options are available?

A: The original L177SDEG09SOL2RM8 is supplied in Tray packaging. Substitute parts are available in Tray (1-338313-2), Tube (1-5747150-3, 1-5747150-4, 1-5747150-6), and Bulk (09641127230, 09641127235, 09661116503, 09661117503, 09661556513, 1-747150-4) packaging. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Which substitute part has the highest inventory availability?

A: TE Connectivity 1-5747150-3 has the highest inventory with 7581 units in stock, followed by 1-5747150-6 with 3384 units. HARTING 09641127235 has 1362 units available. Inventory levels support rapid procurement for high-volume applications.

Q: Are contact finish specifications critical for substitution?

A: Contact finish (gold plating thickness) affects long-term reliability in corrosive environments and contact resistance stability. The original part specifies gold 15.0µin (0.38µm). Substitute parts with gold finish (09661556513, 1-5747150-3, 1-5747150-4, 1-5747150-6) provide equivalent or superior contact protection. Parts without specified contact finish (HARTING 09641127230, 09641127235, 09661116503, 09661117503) may have different finish specifications; contact the manufacturer for detailed finish specifications if corrosion resistance is critical.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: Yes. All substitute parts maintain the 9-position D-Sub receptacle configuration and solder termination method. Mechanical and electrical compatibility is maintained across manufacturers. However, verify that flange mounting configurations are consistent across the assembly to avoid mechanical interference or mounting conflicts.
