Amphenol ICC L77DA15SOL2 D-Sub Receptacle 15-Position Vertical Solder Connector

Part Overview

The L77DA15SOL2 is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products) with vertical through-hole mounting and solder termination. The connector features female sockets configured in a 2-row DA-size shell layout with gold-plated contacts and tin-plated steel housing. This part is currently active in production with 824 units in stock.

Substitute parts become necessary when the original specification requires alternative mounting configurations (panel mount versus through hole), different contact finishing specifications, modified flange features for board-side or mating-side fastening, alternative housing materials, or when component lead times or availability constraints require qualified alternatives from different manufacturers while maintaining connector compatibility and electrical performance.

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC D15S24A4GV00LF (Delta D Series)

The D15S24A4GV00LF is the preferred direct substitute from the same manufacturer. It maintains identical connector specifications (15-position, 2-row DA layout, through-hole solder termination), achieves the full operating temperature range (-55°C to 125°C), matches the 300V voltage rating, and carries RoHS Compliant certification. The connector features female screwlock mating-side fastening and phosphor bronze contacts. Current availability exceeds 35,000 units.

Active High-Inventory Alternatives:

The NorComp 172-E-series (172-E15-213R001, 172-E15-213R011, 172-E15-213R021, 172-E15-213R031, 172-E15-213R911) offers panel-mount configurations with nickel-plated steel shells and active production status. These parts meet UL94 V-0 flammability and ROHS3 compliance requirements. Selection within this series depends on specific flange feature requirements: unthreaded housing (172-E15-213R001), board-side fastening (172-E15-213R011, 172-E15-213R021), mating-side fastening (172-E15-213R031), or dual-side board lock (172-E15-213R911). Operating temperature range is -50°C to 100°C. Current inventory ranges from 1,211 to 6,223 units per variant.

Obsolete Parts to Avoid:

The NorComp 172-015 series (172-015-212R001 and 172-015-212R911) carries obsolete product status and should not be selected for new designs despite available inventory of 3,730 and 3,586 units respectively.

Alternative Through-Hole Options:

TE Connectivity 2-338314-2 (AMPLIMITE HDP-20 series) maintains through-hole mounting with board lock feature, phosphor bronze contacts, and operating range -55°C to 105°C. A-DF 15 PP/Z from Assmann WSW provides through-hole mounting with lower 3A current rating and restricted operating range (-20°C to 105°C) and should be selected only when thermal or current constraints differ from the primary specification.

Frequently Asked Questions (FAQ)

Q: Can NorComp 172-E-series panel-mount connectors substitute for the L77DA15SOL2 through-hole configuration?

A: Panel-mount and through-hole configurations are not directly interchangeable without PCB redesign. NorComp 172-E-series connectors feature panel-mount geometry suitable for front-panel installation with backplate access, while the L77DA15SOL2 is designed for vertical through-hole PCB mounting. Flange feature variations (unthreaded, board-side, mating-side) further differentiate installation methods. Select NorComp substitutes only if your design accommodates panel-mount installation.

Q: What is the impact of current rating differences between the L77DA15SOL2 (7.5A) and most substitute parts (5A or 3A)?

A: Current rating specifies maximum continuous current per contact. The L77DA15SOL2 at 7.5A supports higher per-contact current density. Substitute parts with 5A ratings remain suitable for applications distributing currents across multiple contacts or requiring lower individual contact current. The Assmann A-DF 15 PP/Z at 3A is restricted to low-current signal applications. Verify application current distribution before substituting.

Q: Are nickel-plated shell substitutes (NorComp 172-E series) compatible with tin-plated original part (L77DA15SOL2)?

A: Shell plating differences do not affect mating compatibility. Both tin-plated and nickel-plated steel shells provide electromagnetic shielding and structural integrity. Nickel plating offers enhanced corrosion resistance in certain environments. Contact finish (gold in both cases) determines mating surface compatibility. Shell material finish is a secondary specification and substitution is valid.

Q: What are the implications of the -50°C to 100°C operating range for NorComp substitutes versus the L77DA15SOL2's -55°C to 125°C range?

A: Operating temperature range defines connector performance envelope. NorComp parts are rated 5°C higher on the cold end (-50°C versus -55°C) and 25°C lower on the warm end (100°C versus 125°C). If your application operates within -50°C to 100°C, these substitutes are fully qualified. Applications requiring operation below -50°C or above 100°C require the L77DA15SOL2 or D15S24A4GV00LF (which matches the full range).

Q: Why is the Amphenol D15S24A4GV00LF preferred over other active alternatives?

A: The D15S24A4GV00LF maintains manufacturer continuity (Amphenol ICC), matches all critical performance parameters (15-position, DA layout, 300V, full -55°C to 125°C temperature range, 7.5A per-contact capability), carries identical RoHS Compliant certification, and provides the largest inventory (35,497 units). This combination minimizes design revision and qualification risk.

Q: Are phosphor bronze contact materials (D15S24A4GV00LF, 2-338314-2) interchangeable with brass contacts (L77DA15SOL2)?

A: Contact material does not affect mating compatibility. Both brass and phosphor bronze provide conductive paths and are gold-plated for surface contact. Phosphor bronze offers higher tensile strength and contact pressure consistency. Mating performance with complementary connectors (plugs, male contacts) remains identical. This is a material substitution without functional compatibility impact.
