L77DAH15SOL2RM5 D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The L77DAH15SOL2RM5 is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets with vertical through-hole mounting, solder termination, and a 2-row shell layout (DA/A size). The part is currently active in production with 1,070 units in stock.

Finding equivalent and substitute parts is necessary when the original part becomes unavailable, when procurement lead times are extended, when cost optimization is required, or when design flexibility demands alternative mounting configurations or flange features while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Electrical and mechanical substitutability for D-Sub receptacle connectors is determined by the following critical parameters:

Connector Style, Type, and Position Count: All substitutes must be D-Sub receptacles with 15 positions and 2-row configuration to maintain mating compatibility with existing plug connectors.
Shell Size and Layout: All substitutes must use DA/A (Size 2) shell layout for physical interchangeability.
Mounting Type: The main part uses through-hole vertical mounting. Substitutes may use alternative flange features (board-side, panel-mount, mating-side) as long as the primary mounting method remains through-hole compatible.
Termination: Solder termination is required for all substitutes to ensure compatibility with existing PCB assembly processes.
Contact Material and Finish: Gold-plated contacts and brass base material ensure electrical performance and corrosion resistance. Substitutes must maintain these specifications or equivalent materials.
Temperature and Voltage Ratings: The main part operates at -55°C to 125°C and 300V. Substitutes with lower ratings may be used only if the application does not exceed the substitute's ratings.
Regulatory Compliance: RoHS compliance is required for modern designs. All listed substitutes meet RoHS3 or equivalent standards.

Engineering Selection Recommendations

Preferred Substitutes for Active Production Use:

D15S24A4GV00LF (Amphenol ICC / FCI) - Maintains identical voltage rating (300V) and operating temperature range (-55°C to 125°C) to the main part. RoHS compliant. The lower current rating (5A per contact vs. 7.5A) may be acceptable for applications not requiring maximum current capacity. This part is currently in active production with high inventory (35,497 units).
172-E15-213R001, 172-E15-213R011, 172-E15-213R021, 172-E15-213R031, and 172-E15-213R911 (NorComp Inc.) - All from the active 172-E series with ROHS3 compliance. These parts use nickel-plated steel shells and support alternative flange configurations (unthreaded housing, board-side, or mating-side mounting). The narrower operating temperature range (-50°C to 100°C) and lower current rating (5A) make these suitable for applications within these limits.

Conditional Substitutes:

2-338314-2 (TE Connectivity AMP Connectors) - Active production status with RoHS compliance. Current rating (6A) and temperature range (-55°C to 105°C) differ from the main part. Voltage rating is not specified.
A-DF 15 PP/Z (Assmann WSW Components) - Significantly lower current rating (3A) and voltage rating (250V), with narrower operating temperature range (-20°C to 105°C). This part is suitable only for lower-power applications.

Parts to Avoid:

172-015-212R001 and 172-015-212R911 (NorComp Inc.) - Marked as obsolete. Do not specify for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use D15S24A4GV00LF as a drop-in replacement for L77DAH15SOL2RM5?

A: Yes, for most applications. Both parts share identical electrical ratings (300V, -55°C to 125°C operating range) and the same 15-position DA/A shell layout. The primary difference is that D15S24A4GV00LF has a maximum contact current of 5A per contact versus 7.5A for the main part. Substitution is valid if your application does not exceed 5A per contact. Verify your circuit's current requirements before substituting.

Q: What are the differences between the Amphenol ICC main part and the NorComp 172-E series?

A: The NorComp 172-E series uses nickel-plated steel shells instead of tin-plated and has lower current and temperature ratings (5A, -50°C to 100°C versus 7.5A, -55°C to 125°C). The NorComp parts support panel-mount configurations in addition to board-mount options. Electrical compatibility is maintained for the connector form factor (15-position, DA/A size), but operational limits are more restrictive.

Q: Why should I avoid the obsolete NorComp 172-015 parts?

A: Obsolete parts have ended production and future availability cannot be guaranteed. Existing inventory may be depleted, and procurement difficulties may arise. For new designs and long-term reliability, specify only active-status components from the list provided.

Q: Are all these D-Sub receptacles compatible with the same D-Sub plugs?

A: Yes. All listed 15-position receptacles in DA/A shell size are mechanically and electrically compatible with standard 15-position D-Sub plugs of the same shell size. The connector form factor and pin layout are identical.

Q: How does the Assmann WSW A-DF 15 PP/Z differ in application scope?

A: The A-DF 15 PP/Z is suitable only for lower-power, lower-voltage applications due to its 3A current rating and 250V voltage specification. It also has a narrower operating temperature range (-20°C to 105°C). Specify this part only when application power requirements and temperature constraints align with these limits.

Q: What does shell material finish affect in these connectors?

A: Shell finish (tin plate versus nickel plate) affects corrosion resistance and environmental durability. Tin-plated shells provide standard corrosion protection suitable for most industrial environments. Nickel-plated shells offer enhanced corrosion resistance in harsh or high-humidity environments. Both finishes maintain mechanical shielding and contact continuity.
