L177DE09SOL2 D-Sub 9-Position Receptacle Equivalent & Substitute Parts
Part Overview
The L177DE09SOL2 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 vertical orientation with a DE shell size (1 position layout). The part is currently active in production with 922 units in stock.
D-Sub connectors of this configuration are widely used in industrial, telecommunications, and legacy computing applications. Equivalent and substitute parts become necessary when the primary manufacturer part is unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives that meet the same electrical and mechanical requirements.

Engineering Selection Recommendations
Primary Substitutes (Highest Compatibility):
The HARTING parts 09641127230 and 09641127235 maintain full electrical and mechanical compatibility with the L177DE09SOL2. Both are active production parts with RoHS3 compliance and REACH unaffected status. The 09641127235 variant includes board lock features and tin-plated shell finish, providing enhanced mechanical retention. These parts are suitable for direct substitution in applications where the 300V rating of the original part is not a limiting requirement.
Secondary Substitutes (Functional Equivalence with Design Considerations):
The HARTING parts 09661116503, 09661117503, and 09661556513 provide functional equivalence with mating-side female screwlock features. These parts operate across the full -55°C to 125°C temperature range matching the original specification. The 6.5A current rating is slightly reduced from the 7.5A specification of the L177DE09SOL2. These parts are suitable for applications where mechanical locking at the mating interface is required.
NorComp 172-E Series (Panel Mount Variants):
The NorComp 172-E09 series (172-E09-213R001, 172-E09-213R011, 172-E09-213R021, 172-E09-213R911) are panel mount through-hole variants with active product status. These parts feature brass contacts with gold flash finish and nickel-plated steel shells. The 5A current rating and -50°C to 100°C operating temperature range represent reduced electrical and thermal specifications compared to the L177DE09SOL2. These parts are suitable for panel-mounted applications where the reduced ratings are acceptable.
Obsolete Part (Not Recommended):
The NorComp 172-009-212R021 is marked as obsolete and should not be selected for new designs or long-term supply assurance.
Regulatory Compliance:
All active substitute parts maintain RoHS3 compliance and REACH unaffected status, consistent with the original L177DE09SOL2 specification. All parts carry UL94 V-0 flammability ratings and EAR99 ECCN classification.
Frequently Asked Questions (FAQ)
Q: Can I substitute a HARTING 09641127230 for the Amphenol L177DE09SOL2?
A: Yes. Both parts are 9-position D-Sub receptacles with identical shell size, mounting type, and termination method. The HARTING part maintains the same 7.5A current rating and operating temperature range. The primary difference is the 100V voltage rating of the HARTING part versus the 300V rating of the Amphenol part. Substitution is appropriate for applications where 100V is sufficient.
Q: What is the difference between HARTING 09641127230 and 09641127235?
A: Both are 9-position D-Sub receptacles with identical electrical ratings. The 09641127235 includes board lock features and tin-plated shell finish, whereas the 09641127230 has an unthreaded housing/shell flange. The 09641127235 provides enhanced mechanical retention on the PCB.
Q: Why do the NorComp 172-E09 series parts have lower current ratings?
A: The NorComp 172-E09 series is rated for 5A continuous current, compared to 7.5A for the L177DE09SOL2. This is a design specification difference between manufacturers. The NorComp parts are suitable for applications where 5A is sufficient. The operating temperature range is also narrower (-50°C to 100°C versus -55°C to 125°C).
Q: Are the HARTING parts with female screwlock features (09661116503, 09661117503, 09661556513) direct substitutes?
A: These parts provide functional equivalence with the addition of mating-side female screwlock features for enhanced mechanical coupling. The 6.5A current rating is slightly lower than the 7.5A specification of the L177DE09SOL2. These parts are suitable for applications requiring mechanical locking at the mating interface.
Q: What is the difference between machined and stamped contact forms?
A: The L177DE09SOL2 uses machined contacts, which are individually formed for precision and durability. The HARTING parts 09661116503, 09661117503, and 09661556513 use stamped contacts, which are mass-produced from sheet material. Both contact forms meet the same electrical specifications and are functionally equivalent.
Q: Can I use a panel mount connector (NorComp 172-E09 series) in place of a through-hole connector (L177DE09SOL2)?
A: No. The NorComp 172-E09 series are panel mount through-hole connectors, meaning they are designed to be mounted on the edge of a panel with the connector body extending through the panel. The L177DE09SOL2 is a standard through-hole connector designed for PCB mounting. These are different mounting configurations and are not interchangeable.
Q: What packaging formats are available for these substitute parts?
A: The L177DE09SOL2 is supplied in tray packaging. HARTING substitute parts are supplied in bulk packaging. NorComp substitute parts are supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility; it only affects handling and storage considerations.
Q: Are all substitute parts RoHS compliant?
A: Yes. All active substitute parts listed carry RoHS3 compliance status, consistent with the RoHS compliance of the L177DE09SOL2. The obsolete NorComp 172-009-212R021 also carries RoHS3 compliance but should not be selected for new applications.
Q: What is the significance of the contact finish thickness specification?
A: The L177DE09SOL2 specifies 20.0µin (0.51µm) gold contact finish thickness. This specification ensures consistent electrical contact resistance and corrosion protection. Substitute parts with unspecified contact finish thickness may have different specifications; however, all parts meet the same functional requirements for signal transmission and environmental protection.
