• Physical configuration: Both feature 2-row layout with shell size 2 (DA, A)
• Termination method: Both utilize solder cup termination
• Mounting style: Both are free-hanging, in-line connectors
• Current rating: Both rated at 7.5A per contact
• Operating temperature: Both operate across -55°C ~ 125°C
• Shell material: Both use steel with tin plating
• Contact material finish: Both feature gold plating
• Compliance: Both are RoHS compliant with UL94 V-0 flammability rating

Differentiating Parameters:

• Voltage rating: L77DA15SVF rated at 300V; DAP15S065TLF rated at 1000V
• Flange feature: L77DA15SVF has mating side female screwlock; DAP15S065TLF has unthreaded housing/shell
• Packaging: L77DA15SVF supplied in bag; DAP15S065TLF supplied in tray
• Contact finish thickness: L77DA15SVF at 8.00µin; DAP15S065TLF at 30.0µin

Parameter Comparison

Engineering Selection Recommendations

Both the L77DA15SVF and DAP15S065TLF are active production parts manufactured by Amphenol ICC divisions and carry full RoHS compliance with UL94 V-0 flammability certification. Selection between these parts is determined by application voltage requirements and mechanical interface specifications.

L77DA15SVF Selection Criteria:

• Applications requiring 300V maximum voltage rating
• Installations utilizing mating side female screwlock flange feature
• Bag packaging format compatibility with assembly processes
• Minimum contact finish thickness of 8.00µin acceptable for application

DAP15S065TLF Selection Criteria:

• Applications requiring 1000V maximum voltage rating
• Installations utilizing unthreaded housing/shell flange configuration
• Tray packaging format compatibility with assembly processes
• Enhanced contact finish thickness of 30.0µin for extended service life
• Applications benefiting from GXT™ contact finish technology

Both connectors maintain identical current ratings, operating temperature ranges, and core mechanical dimensions, ensuring functional compatibility within their respective voltage and flange specifications.

Frequently Asked Questions (FAQ)

Q: Can the DAP15S065TLF be used as a direct replacement for the L77DA15SVF?

A: The DAP15S065TLF is electrically and mechanically compatible with the L77DA15SVF for applications operating at or below 300V. However, the flange feature differs: L77DA15SVF uses a mating side female screwlock, while DAP15S065TLF uses an unthreaded housing/shell. Verify mechanical mounting compatibility before substitution.

Q: What is the significance of the voltage rating difference between these parts?

A: The L77DA15SVF is rated for 300V maximum, while the DAP15S065TLF is rated for 1000V maximum. The DAP15S065TLF provides higher voltage capability and is suitable for applications requiring elevated voltage ratings. For applications operating below 300V, both parts are functionally equivalent in this parameter.

Q: How do the contact finish thicknesses compare?

A: The L77DA15SVF features 8.00µin (0.203µm) gold plating, while the DAP15S065TLF features 30.0µin (0.76µm) gold plating with GXT™ technology. The thicker finish on the DAP15S065TLF provides enhanced durability and contact resistance characteristics over extended operational cycles.

Q: Are there packaging differences between these connectors?

A: Yes. The L77DA15SVF is supplied in bag packaging, while the DAP15S065TLF is supplied in tray packaging. Confirm packaging format compatibility with your assembly and handling processes before selection.

Q: Do both parts meet the same compliance standards?

A: Both the L77DA15SVF and DAP15S065TLF are RoHS compliant, carry UL94 V-0 flammability certification, and maintain MSL 1 (Unlimited) moisture sensitivity levels. Both are rated for identical operating temperature ranges of -55°C ~ 125°C.

Q: What is the current rating for each connector?

A: Both connectors are rated for 7.5A per contact. This current capacity is identical across both part numbers and does not serve as a differentiating factor for substitution decisions.

Q: Which part should be selected for new designs?

A: Selection depends on application voltage requirements and mechanical interface specifications. For applications requiring 1000V capability or enhanced contact durability, the DAP15S065TLF is appropriate. For applications operating at 300V with mating side screwlock requirements, the L77DA15SVF is suitable. Both are active production parts with adequate inventory availability.
