L77SDEG09SOL2RM8 D-Sub Receptacle Equivalent & Substitute Parts
Part Overview
The L77SDEG09SOL2RM8 is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features female sockets in a DE/E shell size configuration with board-side M3 mounting and mating-side female screwlock. The connector is actively produced and maintains 853 units in current inventory.
Substitute parts are identified when equivalent D-Sub receptacle connectors share the same core functional specifications: 9-position configuration, 2-row layout, DE/E shell size, through-hole mounting, solder termination, and female socket contact type. Alternative models become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements permit variations in secondary parameters such as contact finish, current rating, or flange configuration.

Engineering Selection Recommendations
All identified substitute parts maintain active product status and meet the core functional requirements of the L77SDEG09SOL2RM8. Selection criteria are based on compliance certifications and manufacturing status.
RoHS Compliance Tier: Parts 09641127230, 09641127235, 09661116503, 09661117503, 09661556513, and 1-338313-2 carry ROHS3 Compliant certification, representing the most current regulatory compliance standard. Parts 1-5747150-3, 1-5747150-4, 1-5747150-6, and 1-747150-4 carry RoHS Compliant or RoHS non-compliant status. The L77SDEG09SOL2RM8 itself is RoHS Compliant.
Operating Temperature Range: The L77SDEG09SOL2RM8 operates across -55°C to 125°C. Parts 09641127230 and 09641127235 operate across -20°C to 125°C, representing a narrower low-temperature range. Parts 09661116503, 09661117503, 09661556513, and all TE Connectivity variants maintain the full -55°C to 125°C range or -55°C to 105°C range. Applications requiring full -55°C operation should prioritize parts with matching or superior low-temperature specifications.
Current Rating: The L77SDEG09SOL2RM8 is rated for 3A. All substitute parts exceed this rating (6A to 7.5A), providing design margin for higher-current applications. No substitution limitation exists based on current capacity.
Voltage Rating: The L77SDEG09SOL2RM8 is rated for 250V. Parts 09641127230 and 09641127235 are rated for 100V. Parts 1-5747150-3, 1-5747150-4, 1-5747150-6, and 1-747150-4 are rated for 125V. Applications requiring 250V operation should prioritize the original part or verify that lower-voltage substitutes meet system requirements.
Contact Finish: The L77SDEG09SOL2RM8 features gold-plated contacts. Parts 09641127230, 09641127235, 09661116503, and 09661117503 do not specify contact finish. Parts 09661556513, 1-338313-2, 1-5747150-3, 1-5747150-4, 1-5747150-6, and 1-747150-4 feature gold contact finish, matching the original specification.
Flange Configuration: The L77SDEG09SOL2RM8 features board-side M3 mounting with mating-side female screwlock. Substitute parts offer varied flange configurations: board-side 4-40, housing/shell unthreaded, or mating-side female screwlock 4-40. PCB mounting hole patterns must be verified for compatibility with the selected substitute.
Frequently Asked Questions (FAQ)
Q: Can I substitute a HARTING 09641127235 for the L77SDEG09SOL2RM8?
A: The 09641127235 meets all core functional requirements: 9-position D-Sub receptacle, 2-row configuration, DE/E shell size, through-hole solder termination, and UL94 V-0 flammability rating. However, three parameters differ: the 09641127235 operates at -20°C to 125°C (versus -55°C to 125°C), is rated for 100V (versus 250V), and does not specify contact finish. Substitution is valid only if your application does not require -55°C operation or 250V rating.
Q: What is the difference between the TE Connectivity 1-5747150-3, 1-5747150-4, and 1-5747150-6?
A: All three parts are TE Connectivity AMPLIMITE HD-20 series 9-position D-Sub receptacles with identical core specifications. The primary difference is contact finish thickness: 1-5747150-3 specifies flash thickness, while 1-5747150-4 and 1-5747150-6 specify 30.0µin (0.76µm) thickness. RoHS status also differs: 1-5747150-3 and 1-5747150-4 are ROHS3 Compliant, while 1-5747150-6 is RoHS Compliant. All three are functionally equivalent for standard applications.
Q: Why does the 1-747150-4 show RoHS non-compliant status?
A: The 1-747150-4 is an older TE Connectivity AMPLIMITE HD-20 variant that predates current RoHS regulations. It remains functionally equivalent to the L77SDEG09SOL2RM8 in all core parameters but may not be suitable for applications requiring RoHS compliance certification. Use only in legacy systems or where regulatory exemptions apply.
Q: Can I use a substitute with a lower current rating?
A: No. All identified substitutes are rated for 6A to 7.5A, which exceeds the L77SDEG09SOL2RM8 rating of 3A. No substitute with a lower current rating is provided. Current rating is a non-negotiable parameter for electrical safety.
Q: What is the significance of the flange feature differences?
A: The L77SDEG09SOL2RM8 uses M3 board-side mounting with M3 mating-side female screwlock. Substitutes offer board-side 4-40, housing/shell unthreaded, or mating-side female screwlock 4-40 configurations. These differences affect PCB hole pattern, mounting hardware, and mechanical interface. Verify that your PCB design accommodates the flange configuration of the selected substitute before implementation.
Q: Are HARTING and TE Connectivity substitutes electrically interchangeable?
A: Yes. Both manufacturers' parts meet the same core electrical specifications: 9-position D-Sub receptacle, 2-row configuration, DE/E shell size, through-hole solder termination, UL94 V-0 rating, and MSL 1. Electrical interchangeability is confirmed. Mechanical interchangeability depends on flange configuration and PCB hole pattern compatibility.
Q: Which substitute offers the best compliance profile?
A: Parts 09641127230, 09641127235, 09661116503, 09661117503, 09661556513, and 1-338313-2 carry ROHS3 Compliant certification, representing the most current regulatory standard. These parts are recommended for new designs requiring the highest compliance certification level.
Q: Can I use the 09641127230 in a -55°C environment?
A: No. The 09641127230 is rated for -20°C to 125°C operation. For applications requiring -55°C operation, select parts with matching or superior low-temperature specifications: 09661116503, 09661117503, 09661556513, or the TE Connectivity variants (1-338313-2, 1-5747150-3, 1-5747150-4, 1-5747150-6, 1-747150-4).
Q: What packaging options are available?
A: The L77SDEG09SOL2RM8 is supplied in Tray packaging. Substitutes 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 inventory management and component handling but does not affect electrical or mechanical function.
