L77DAF15S

Part Overview

The L77DAF15S is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products) with female sockets termination. The connector features solder cup termination and is designed for free-hanging (in-line) mounting applications. This is an active product with RoHS compliance and unlimited moisture sensitivity level (MSL-1), making it suitable for long-term storage and deployment in various environmental conditions.

Alternative models are necessary to accommodate different application requirements, such as variations in voltage rating, contact finish specifications, packaging formats, or supply availability while maintaining core functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the L77DAF15S and DAP15S065TLF are active products with full RoHS compliance and identical flammability ratings (UL94 V-0). The primary differentiator is the voltage rating: the L77DAF15S supports 300V applications, while the DAP15S065TLF supports up to 1000V, making it suitable for higher-voltage environments.

The DAP15S065TLF provides enhanced contact durability through thicker gold plating (30.0µin versus 8.00µin) and offers GXT™ contact finish technology with copper alloy materials. Both connectors maintain identical current ratings (7.5A) and operating temperature specifications (-55°C to 125°C), ensuring functional equivalence for thermal performance and load handling.

Selection should be based on voltage requirements of the target application. The L77DAF15S is appropriate for standard 300V applications, while the DAP15S065TLF is required for applications exceeding 300V or requiring superior contact surface characteristics. Packaging format differences (bag versus tray) may influence high-volume procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can DAP15S065TLF be used as a direct replacement for L77DAF15S?

A: Yes, provided the application voltage rating does not exceed the specifications of the selected connector. Both parts share identical mechanical configuration (15-position, 2-row D-Sub layout), mounting style (free-hanging in-line), current rating (7.5A), and termination method (solder cup). The primary consideration is voltage compatibility with your circuit requirements.

Q: What are the key substitution criteria for these D-Sub connectors?

A: Substitution compatibility requires matching the connector type (receptacle, female sockets), number of positions (15), shell size and layout (2 DA/A), mounting configuration (free-hanging in-line), and termination method (solder cup). Voltage rating and contact finish specifications may vary based on application needs, as higher voltage ratings and enhanced contact finishes provide greater margin for demanding environments.

Q: How do the contact finishes differ between these parts?

A: The L77DAF15S features standard gold plating at 8.00µin thickness on brass contacts. The DAP15S065TLF provides gold GXT™ finish at 30.0µin thickness on copper alloy contacts, offering significantly greater contact durability and lower contact resistance characteristics, particularly beneficial for applications requiring extended cycle life or superior signal integrity.

Q: What is the impact of different packaging formats?

A: The L77DAF15S is supplied in bag packaging, while the DAP15S065TLF is supplied in tray packaging. Tray packaging provides improved protection and handling efficiency in automated assembly environments. For low-volume applications, bag packaging is standard. For high-volume production, tray packaging may offer cost advantages and supply chain efficiency.

Q: Are both parts suitable for long-term storage?

A: Yes. Both connectors are classified as MSL-1 (unlimited moisture sensitivity level), indicating they do not require special moisture-controlled storage conditions and can be stored indefinitely under standard environmental conditions without degradation.
