L77DAH15S D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The L77DAH15S is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets with solder cup termination, designed for free-hanging in-line applications. The part is currently active in production with 977 units in stock. D-Sub receptacle connectors are essential components in applications requiring standardized signal transmission interfaces, and equivalent substitutes may be necessary due to supply chain considerations, packaging preferences, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L77DAH15S is determined by the following critical parameters that must remain constant across equivalent parts:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 15
• Number of Rows: 2
• Shell Size, Connector Layout: 2 (DA, A)
• Termination Type: Solder Cup
• Mounting Type: Free Hanging (In-Line)
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Compliance: Required

Allowable Variation Parameters:

• Manufacturer and series designation
• Packaging format (Bag vs. Tray)
• Contact finish specifications (Gold vs. Gold GXT™)
• Contact finish thickness (within acceptable ranges)
• Voltage rating (equal to or greater than 300V)
• Current rating (equal to or greater than 7.5A)
• Flange feature design (Cable Side vs. Housing/Shell)
• Shell material finish (Steel, Tin Plated acceptable)

The substitute part DAP15S065TLF meets all mandatory matching parameters and maintains electrical and mechanical compatibility with the L77DAH15S.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: L77DAH15S

The L77DAH15S remains the primary specification when available. This part is actively manufactured by Amphenol ICC (Commercial Products) with 977 units in current stock inventory. It carries full RoHS compliance and meets all standard D-Sub receptacle specifications for 15-position applications.

Substitute Part: DAP15S065TLF

The DAP15S065TLF is a direct functional equivalent manufactured by Amphenol ICC (FCI) and is eligible for substitution under the following conditions:

• All mandatory connector parameters match exactly (position count, shell size, termination type, mounting configuration)
• Electrical ratings are equal or superior (1000V voltage rating exceeds the 300V requirement; 7.5A current rating matches specification)
• Compliance certifications are equivalent (RoHS Compliant, UL94 V-0, EAR99, identical HTSUS classification)
• Operating temperature range is identical (-55°C ~ 125°C)
• Contact finish specifications are compatible (Gold GXT™ with increased thickness provides enhanced durability)

The primary difference is packaging format (Tray vs. Bag) and flange feature design (Housing/Shell unthreaded vs. Cable Side 4-40). These differences do not affect electrical or mechanical compatibility in the connector interface itself.

Inventory Consideration:

DAP15S065TLF has 1076 units in stock, providing an alternative supply source when L77DAH15S availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can DAP15S065TLF be used as a direct replacement for L77DAH15S in existing designs?

A: Yes. Both connectors are 15-position D-Sub receptacles with identical shell size (2 DA/A), solder cup termination, and free-hanging in-line mounting. The connector interface is mechanically and electrically identical. The substitute part meets or exceeds all electrical specifications.

Q: What is the difference between the flange features (Cable Side 4-40 vs. Housing/Shell Unthreaded)?

A: The L77DAH15S features a cable-side flange with 4-40 threaded mounting holes. The DAP15S065TLF features an unthreaded housing/shell flange. This affects the mounting method to the enclosure or backplate but does not affect the connector-to-connector interface or signal transmission.

Q: Why does DAP15S065TLF have a higher voltage rating (1000V vs. 300V)?

A: The higher voltage rating indicates enhanced dielectric properties and insulation capability. This is a superior specification that maintains full compatibility with applications rated for 300V. No design modification is required.

Q: What is the significance of the contact finish thickness difference (8.00µin vs. 30.0µin)?

A: The DAP15S065TLF features a thicker gold plating (30.0µin) compared to the L77DAH15S (8.00µin). Thicker plating generally provides improved wear resistance and contact durability over extended mating cycles. Both finishes are compatible with standard D-Sub applications.

Q: Does the packaging difference (Bag vs. Tray) affect connector performance?

A: No. Packaging format affects handling, storage, and logistics only. It does not impact electrical performance, mechanical fit, or functional compatibility. Tray packaging may offer advantages for automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both L77DAH15S and DAP15S065TLF are RoHS Compliant with identical MSL rating (1 - Unlimited) and ECCN classification (EAR99).

Q: Can these connectors be intermated with each other?

A: Yes. Both parts are 15-position D-Sub receptacles with identical shell size and pin configuration. They are mechanically and electrically compatible for mating with standard 15-position D-Sub plugs.
