L177DFE09SOL2RM8 D-Sub Receptacle Equivalent & Substitute Parts
Part Overview
The L177DFE09SOL2RM8 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 maintains 719 units in current inventory stock.
D-Sub receptacle connectors serve as mating interfaces for signal transmission in industrial, telecommunications, and data acquisition applications. Equivalent and substitute parts become necessary when original inventory is depleted, when alternative packaging formats are required, or when design modifications necessitate different mounting configurations or electrical characteristics within acceptable operating parameters.

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, Female Sockets)
- Number of positions (9)
- Number of rows (2)
- Shell size and layout (1 / DE, E)
- Termination method (Solder)
- Mounting classification (Through Hole)
Electrical Compatibility Parameters:
- Current rating must equal or exceed 7.5A
- Voltage rating must equal or exceed 300V
- Operating temperature range must encompass -55°C to 125°C
Material and Compliance Parameters:
- Material flammability rating UL94 V-0
- RoHS compliance status (RoHS Compliant or ROHS3 Compliant acceptable)

Substitute parts are grouped into two categories based on mounting configuration differences:
Category A: Panel Mount Configuration – Parts with panel-mount flange features that directly replace the L177DFE09SOL2RM8 in applications requiring front-panel installation.
Category B: Through-Hole Board-Mount Configuration – Parts with board-side or mating-side flange features that require circuit board layout modifications but maintain electrical and mechanical compatibility within the 9-position, 2-row, shell size 1 D-Sub standard.

Engineering Selection Recommendations
Direct Panel-Mount Replacement (Electrical and Mechanical Equivalence):
The NorComp Inc. part number 191-009-213L571 maintains panel-mount, through-hole configuration identical to the L177DFE09SOL2RM8. This part is actively produced, ROHS3 compliant, and carries UL94 V-0 flammability rating. However, the current rating of 5A is below the 7.5A specification of the original part. This part is suitable only for applications where the actual circuit current requirement does not exceed 5A.
Through-Hole Board-Mount Alternatives (Electrical Compatibility with Configuration Change):
HARTING part numbers 09641127230 and 09641127235 maintain the 7.5A current rating and UL94 V-0 compliance. Both are ROHS3 compliant and actively produced. Part 09641127235 includes board-lock features and tin-plated shell finish. However, both parts specify 100V voltage rating, which is below the 300V specification of the original part. These parts are suitable for applications where the actual circuit voltage requirement does not exceed 100V.
HARTING part numbers 09661116503, 09661117503, and 09661556513 maintain the full -55°C to 125°C operating temperature range and UL94 V-0 compliance. All three are ROHS3 compliant and actively produced. However, all three specify 6.5A current rating, below the 7.5A specification, and voltage rating is not specified. Part 09661556513 includes gold contact finish and board-lock features.
TE Connectivity AMP Connectors parts 1-5747150-3, 1-5747150-4, 1-5747150-6, and 1-747150-4 are actively produced with gold contact finish and tin-plated steel shells. Parts 1-5747150-4 and 1-5747150-6 are RoHS Compliant. However, all four parts specify 6A current rating and 125V voltage rating, both below the original part specifications. Part 1-747150-4 is RoHS non-compliant and should not be selected for new designs requiring RoHS compliance.
Compliance Considerations:
All substitute parts except 1-747150-4 maintain RoHS compliance status (either RoHS Compliant or ROHS3 Compliant). All substitute parts maintain UL94 V-0 flammability rating and moisture sensitivity level 1 (Unlimited). All substitute parts are actively produced with current inventory availability.
Frequently Asked Questions (FAQ)
Q: Can the HARTING 09641127235 directly replace the L177DFE09SOL2RM8 in all applications?
A: The HARTING 09641127235 maintains 9-position, 2-row, shell size 1 (DE, E) configuration with 7.5A current rating and UL94 V-0 compliance. However, it specifies 100V voltage rating compared to the original 300V specification. Direct replacement is limited to applications where circuit voltage does not exceed 100V. The mounting configuration differs (board-side flange versus panel-mount), requiring circuit board layout modification.
Q: What is the significance of the current rating difference between the L177DFE09SOL2RM8 (7.5A) and the TE Connectivity parts (6A)?
A: Current rating represents the maximum continuous current the connector contacts can safely conduct without exceeding temperature limits. The TE Connectivity parts with 6A rating are suitable for applications where actual circuit current does not exceed 6A. Applications requiring the full 7.5A capacity must use parts with equal or higher current rating specifications.
Q: Why do some substitute parts not specify voltage rating?
A: Voltage rating specification is provided by manufacturers based on dielectric breakdown testing and design validation. Parts without specified voltage rating in the provided data cannot be confirmed for operation at the original 300V specification. Selection of such parts requires verification against the manufacturer's complete technical documentation.
Q: Are all substitute parts suitable for the full -55°C to 125°C operating temperature range?
A: No. HARTING parts 09641127230 and 09641127235 specify -20°C to 125°C operating range, which does not encompass the -55°C lower limit of the original part. TE Connectivity parts specify -55°C to 105°C, which does not encompass the 125°C upper limit. Selection must match the actual application temperature requirements.
Q: What is the difference between panel-mount and through-hole board-mount configurations?
A: Panel-mount connectors (L177DFE09SOL2RM8 and 191-009-213L571) feature flanges designed for installation through a front panel with fastening from the rear. Through-hole board-mount connectors feature flanges designed for installation directly on circuit boards with fastening to the board structure. These configurations require different mechanical mounting approaches and cannot be interchanged without circuit board redesign.
Q: Is the NorComp 191-009-213L571 a suitable replacement despite the 5A current rating?
A: The NorComp part maintains panel-mount configuration and -55°C to 125°C operating range with ROHS3 compliance and UL94 V-0 rating. However, the 5A current rating is below the 7.5A specification. This part is suitable only for applications where actual circuit current does not exceed 5A. Applications requiring higher current capacity must select parts with 7.5A or higher rating.
Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?
A: Both statuses indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant typically refers to the original RoHS Directive compliance. ROHS3 Compliant refers to compliance with the updated RoHS Directive 2011/65/EU. Both are acceptable for new designs; ROHS3 Compliant represents the current regulatory standard.
Q: Can parts with different contact finish materials (gold versus unspecified) be interchanged?
A: Contact finish affects electrical conductivity, corrosion resistance, and mating force characteristics. The L177DFE09SOL2RM8 specifies gold contact finish at 30.0µin thickness. Parts with unspecified contact finish cannot be confirmed for equivalent electrical performance. Parts with specified gold finish (HARTING 09661556513, TE Connectivity 1-5747150 series) maintain contact finish equivalence.
Q: What packaging format differences exist among the substitute parts?
A: The L177DFE09SOL2RM8 is supplied in Tray packaging. Substitute parts are supplied in Bulk (HARTING parts, TE Connectivity 1-747150-4) or Tube (TE Connectivity 1-5747150 series) packaging. Packaging format affects handling, storage, and component counting procedures but does not affect electrical or mechanical performance.
