Amphenol ICC L77DAH15ST D-Sub 15-Position Receptacle Connector

Part Overview

The L77DAH15ST is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products) for through-hole solder termination applications. This connector features female socket contacts, a 2-row configuration with DA/A shell size, and is rated for 300V at 7.5A per contact. The part is currently active in production status with RoHS compliance certification and unlimited moisture sensitivity level (MSL 1).

Finding equivalent and substitute components becomes necessary when inventory constraints, manufacturing discontinuations, or application-specific requirements such as different mounting types (panel mount versus board-side flange) or shell material finishes (tin versus nickel plating) affect component availability or operational parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the L77DAH15ST is determined by the following critical parameters: 15-position count, 2-row configuration, DA/A shell size, D-Sub connector style, receptacle female socket type, solder termination, and UL94 V-0 flammability rating. Parts meeting these baseline requirements are categorized by secondary parameters that affect compatibility within specific application contexts.

Primary Substitution Criteria (Must Match):

Connector Type: Receptacle, Female Sockets
Number of Positions: 15
Number of Rows: 2
Shell Size: 2 (DA, A)
Connector Style: D-Sub
Termination Method: Solder
Flammability Rating: UL94 V-0

Secondary Substitution Parameters (Determine Application Suitability):

Mounting Type (Through Hole vs. Panel Mount)
Flange Feature (Board Side vs. Mating Side vs. Housing/Shell mounting)
Shell Material Finish (Tin Plated vs. Nickel Plated)
Current Rating (7.5A vs. 5A vs. 6A vs. 3A per contact)
Voltage Rating (300V vs. 250V vs. unspecified)
Operating Temperature Range (-55°C to 125°C vs. -50°C to 100°C vs. -55°C to 105°C vs. -20°C to 105°C)
Contact Material (Brass vs. Phosphor Bronze vs. Copper Alloy)
Dielectric Material composition
Compliance Certifications (RoHS vs. ROHS3, REACH status)

Substitution across secondary parameters requires technical evaluation of the intended circuit environment, thermal requirements, and regulatory compliance context.

Engineering Selection Recommendations

Fully Compatible Substitutes (Same Manufacturer, Active Status): The D15S24A4GV00LF from Amphenol ICC (FCI) maintains equivalent operating temperature (-55°C to 125°C), voltage rating (300V), flammability (UL94 V-0), and RoHS compliance. The primary difference is the mating side screwlock flange feature rather than board-side mounting. This part demonstrates 35,497 units in current inventory and represents the highest stock availability for direct substitution.

Active NorComp 172-E Series (Panel Mount Configuration): The 172-E15-213R011, 172-E15-213R021, and 172-E15-213R911 represent active production alternatives manufactured by NorComp Inc. These components are ROHS3 compliant and feature nickel-plated steel shells. The reduced current rating (5A versus 7.5A) requires application evaluation. The 172-E15-213R011 and 172-E15-213R021 both offer board-side (4-40) flanges, while 172-E15-213R031 provides mating-side mounting. The 172-E15-213R911 includes female screwlock features for both board and mating sides with board lock functionality. Operating temperature maximum (-50°C to 100°C upper limit) represents a 25°C reduction from the L77DAH15ST specification.

TE Connectivity AMPLIMITE HDP-20 Series (Through-Hole, Active): The 2-338314-2 connector maintains through-hole mounting and RoHS compliance with a higher current capacity (6A) relative to NorComp alternatives. Temperature specification (-55°C to 105°C) aligns with minimum cold-temperature performance. Phosphor bronze contact material and board lock features are provided. The housing/shell flange configuration (M3) differs from the L77DAH15ST board-side mounting.

Obsolete NorComp 172-015 Series: The 172-015-212R001 and 172-015-212R911 are classified as obsolete product status. These tin-plated steel shell connectors feature reduced current ratings (5A) and narrower temperature ranges (-50°C to 100°C). Selection is not recommended for new designs.

Limited Application Scope (A-DF 15 PP/Z): The Assmann WSW A-DF 15 PP/Z connector exhibits significantly reduced electrical characteristics: 3A current rating (60% of the L77DAH15ST specification), 250V voltage rating (versus 300V), and restricted operating temperature minimum (-20°C versus -55°C). This component is limited to applications not requiring the full electrical performance envelope of the primary part.

Frequently Asked Questions (FAQ)

Q: Can I substitute the L77DAH15ST with a 172-E15-213R011 from NorComp? A: Mechanical and electrical compatibility exists for 15-position, 2-row D-Sub receptacle applications with solder termination and UL94 V-0 flammability. However, the 172-E15-213R011 exhibits a 5A current rating (versus 7.5A) and maximum operating temperature of 100°C (versus 125°C). Panel-mount configuration differs from the L77DAH15ST board-side flange feature. Application evaluation is required for circuits approaching or exceeding 5A per contact or sustained operation above 100°C.

Q: What is the difference between board-side and mating-side flange features? A: Board-side flanges (4-40) mount the connector perpendicular to the circuit board surface with fastener holes on the connector body. Mating-side flanges attach the connector to the mating plug connector. Housing/shell unthreaded flanges provide basic shell grounding or retention without threaded fastener mounting. These configurations are not interchangeable without mechanical redesign.

Q: Are NorComp 172-E components suitable for replacement in existing designs using the L77DAH15ST? A: The 172-E15 series provides functional D-Sub 15-position receptacle capability with different electrical characteristics. Designs must accommodate the reduced current rating (5A), lower maximum operating temperature (100°C), and potential electromagnetic compatibility differences due to nickel-plated shell finish. Physical mounting differences require evaluation of available space and fastener configurations.

Q: What is the difference between tin-plated and nickel-plated shell finishes? A: Tin plating (8.00µin thickness on the L77DAH15ST) provides corrosion resistance and solderability. Nickel plating (flash thickness on NorComp 172-E series) offers enhanced wear resistance and improved shielding effectiveness. Shell material finish selection affects long-term reliability in corrosive environments and electromagnetic shielding performance. Substitution requires environmental exposure analysis.

Q: Can the A-DF 15 PP/Z be used as a general substitute? A: The A-DF 15 PP/Z serves only applications operating below 3A per contact, below 250V, and within the -20°C to 105°C temperature range. The reduced electrical ratings and narrower cold-temperature range limit applicability to low-power signal distribution or non-critical thermal environments. This part is not suitable for direct replacement in designs utilizing the full 7.5A capacity or -55°C operation.

Q: Should I select D15S24A4GV00LF as the primary substitute? A: The D15S24A4GV00LF from Amphenol ICC (FCI) maintains equivalent electrical and thermal specifications (-55°C to 125°C, 300V, RoHS compliance). The mating-side screwlock flange differs mechanically from the L77DAH15ST board-side configuration, requiring mechanical compatibility assessment. Available inventory (35,497 units) ensures near-term supply. Selection is appropriate for applications where mating-side female screwlock fastening is compatible with the assembly design.

Q: Are all substitute parts RoHS compliant? A: The L77DAH15ST and D15S24A4GV00LF are RoHS Compliant. NorComp 172-E and 172-015 series components are ROHS3 Compliant. The 2-338314-2 is RoHS Compliant. The A-DF 15 PP/Z is ROHS3 Compliant. ROHS3 certification (Directive 2011/65/EU) applies to ROHS2 requirements (Directive 2002/95/EC) with additional exemptions. Both certifications satisfy current RoHS regulatory requirements.
