L77DAH15SOL2RM8 Equivalent & Substitute Parts
Part Overview
The L77DAH15SOL2RM8 is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products), featuring female socket contacts for signal applications. This vertically-mounted, through-hole solder termination connector is actively produced and held in inventory (963 pcs). The connector employs board-side and mating-side screwlock features with 4-40 mounting hardware.
Substitute parts are identified to provide design flexibility when the primary part becomes unavailable, when alternative compliance certifications are required, or when specific flange configurations better suit application requirements.

Substitute Part Grouping Explanation
Substitution eligibility for D-Sub receptacle connectors is determined by maintaining commonality in core electrical and mechanical parameters: 15-position configuration, 2-row layout (DA, A shell size), female socket receptacle type, through-hole or panel-mount solder termination, UL94 V-0 flammability rating, and operating temperature ranges that encompass the primary application envelope.
Key substitution parameters include:
- Connector position and row configuration (15 positions, 2 rows, DA/A shell size)
- Termination method (solder compatible)
- Contact material and finish (gold-plated precious metals or gold flash on brass/phosphor bronze)
- Voltage and current ratings (minimum 5A current, 250V or higher voltage)
- Flammability compliance (UL94 V-0)
- Operating temperature compatibility (-50°C to 125°C minimum range)
- Shell finish (tin or nickel plated steel)
Substitute parts are grouped by mounting configuration: through-hole vertical mount with board-lock and screwlock features. Parts with panel-mount or alternative flange configurations are included when electrical and thermal parameters align with through-hole specifications, allowing mechanical adaptation in circuit design.

Engineering Selection Recommendations
Primary Substitutes (Recommended)
The D15S24A4GV00LF (Amphenol FCI, Delta D series) is the most direct electrical equivalent, maintaining identical operating temperature range (-55°C to 125°C), voltage rating (300V), and RoHS compliance. This through-hole vertical-mount receptacle with board-lock and mating-side screwlock features provides maximum compatibility with the primary part's mechanical interface.
The 2-338314-2 (TE Connectivity AMPLIMITE HDP-20 series) operates within the -55°C to 105°C temperature envelope and delivers 6A current capacity, making it suitable for applications not demanding the full 125°C upper thermal limit. This active product carries RoHS compliance and features board-lock functionality with M3 housing/shell mounting hardware.
Secondary Substitutes (Panel-Mount Alternatives)
The NorComp 172-E series (172-E15-213R001, 172-E15-213R011, 172-E15-213R021, 172-E15-213R031, 172-E15-213R911) comprises active products with ROHS3 compliance. These parts operate at -50°C to 100°C and deliver 5A per contact, suitable for applications within reduced thermal limits. Panel-mount configurations with unthreaded housings or 4-40 board-side/mating-side flanges are available to accommodate alternative mechanical mounting schemes. Nickel-plated steel shells provide enhanced corrosion resistance compared to tin plating.
Obsolete Parts (Limited Use)
The NorComp 172-015 series (172-015-212R001, 172-015-212R911) are obsolete and held in large existing inventory (3730 and 3586 units). These parts deliver 5A current capacity and operate at -50°C to 100°C with ROHS3 compliance. Use is restricted to applications tolerating reduced thermal operating range and inventory drawdown schedules.
Lower-Rated Alternative (Constrained Applications)
The Assmann A-DF 15 PP/Z operates at 3A per contact with 250V voltage rating and -20°C to 105°C operating range, limiting its utility to low-current or moderate-temperature applications. This through-hole connector is provided as a last-resort alternative only.
Frequently Asked Questions (FAQ)
Q: Can the NorComp 172-E15 series directly replace the L77DAH15SOL2RM8 in high-temperature applications?
A: No. The L77DAH15SOL2RM8 operates to 125°C; the 172-E15 series operates to 100°C maximum. Applications requiring sustained operation above 100°C must retain the primary part or transition to the D15S24A4GV00LF, which matches the 125°C upper limit.
Q: What is the significance of the different flange features (board-side, mating-side, unthreaded housing)?
A: Flange features determine mechanical mounting geometry. The L77DAH15SOL2RM8 includes both board-side (4-40) and mating-side female screwlock (4-40), enabling two-point mechanical locking. Panel-mount variants with unthreaded housings or single flanges require mechanical adaptation in the PCB cutout or backplane design. Verify panel thickness and mounting hardware compatibility during substitution.
Q: Are the NorComp 172-015 obsolete series still acceptable for new designs?
A: The obsolete designation indicates discontinued production. While 3730+ units remain in current inventory, applications requiring long-term supply continuity or lifecycle support should select active products: D15S24A4GV00LF, 2-338314-2, or the 172-E15 series.
Q: What is the current capacity difference between 5A and 7.5A rated connectors?
A: The L77DAH15SOL2RM8 rates 7.5A per contact; most substitutes rate 5A per contact. For high-current designs (greater than 5A per line), the primary part is required. The D15S24A4GV00LF specifies 5A per contact. Verify actual application current per contact against connector ratings.
Q: How do different shell finishes (tin-plated vs. nickel-plated) affect substitution?
A: Tin plating (L77DAH15SOL2RM8, 2-338314-2, A-DF 15 PP/Z) provides standard EMI shielding and cost effectiveness. Nickel plating (172-E15 series, D15S24A4GV00LF) offers enhanced corrosion resistance in humid or corrosive environments. Shell finish is a secondary parameter not restricting substitution; select based on environmental exposure and cost requirements.
Q: Are there compatibility issues between gold contact finishes on different connector substrates?
A: All listed substitutes employ gold contact finishes (full gold or gold flash) compatible with standard mating plugs. Electrical continuity and contact resistance characteristics are maintained across all listed parts. No contact finish incompatibilities exist among these D-Sub receptacles.
Q: Can panel-mount NorComp 172-E15 variants physically fit a through-hole L77DAH15SOL2RM8 footprint?
A: Panel-mount and through-hole variants share identical pin configurations and hole positioning for solder termination. Mechanical panel mounting flanges on 172-E15 series require PCB cutout geometry accommodating flange dimensions. Verify flange size and mounting hole patterns against available panel space and cutout design.
Q: What RoHS certification level applies to substitute selection?
A: The L77DAH15SOL2RM8 carries RoHS Compliance (standard). NorComp substitutes carry ROHS3 Compliance, indicating updated hazardous substance restrictions. Both compliance levels are acceptable for new designs; ROHS3 represents the current regulatory standard. No RoHS level incompatibility restricts substitution.
