Key Parameters

Substitute Part Grouping Explanation

Equivalent substitutes for the L717DFD50PA are identified based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 50
• Number of Rows: 3
• Shell Size, Connector Layout: 5 (DD, D)
• Mounting Type: Right Angle
• Termination: Solder
• Shell Material, Finish: Steel, Tin Plated
• Voltage Rating: 300V
• Connector Style: D-Sub
• Flange Feature: Housing/Shell (Unthreaded)
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts DD50P564TXLF and DD50P564GTXLF are manufactured by Amphenol ICC (FCI) and maintain compatibility with the original L717DFD50PA across all mandatory electrical and mechanical parameters. Variations in current rating per contact, backset spacing, contact finish thickness, and operating temperature maximum are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

L717DFD50PA Selection Criteria:

• Applications requiring maximum operating temperature of 155°C
• Designs specifying 7.5A current rating per connector
• Backset spacing requirement of 0.319" (8.10mm)
• Panel mount configuration with through hole termination
• Original equipment manufacturer (OEM) specifications requiring DF series designation

DD50P564TXLF Selection Criteria:

• Applications with operating temperature maximum of 125°C
• Designs tolerating 5A per contact current rating
• Backset spacing of 0.409" (10.40mm)
• Through hole right angle solder termination
• ROHS3 compliance requirement
• Tray packaging for automated assembly processes
• REACH unaffected status for specific regulatory environments

DD50P564GTXLF Selection Criteria:

• Applications with operating temperature maximum of 125°C
• Designs tolerating 5A per contact current rating
• Backset spacing of 0.409" (10.40mm)
• Through hole right angle solder termination
• RoHS compliance requirement
• Bulk packaging for high-volume procurement
• REACH affected status consideration

All three parts maintain active product status and comply with UL94 V-0 flammability rating and 300V voltage specification. Selection between alternatives depends on specific application thermal requirements, current distribution needs, and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can DD50P564TXLF or DD50P564GTXLF be used as direct replacements for L717DFD50PA?

A: Both substitute parts maintain electrical and mechanical compatibility across 50 position, 3 row, shell size 5 (DD, D) D-Sub plug connector specifications. However, applications requiring 7.5A current rating or operating temperatures above 125°C must use the original L717DFD50PA. Backset spacing differs between the original (0.319") and substitutes (0.409"), requiring PCB layout verification.

Q: What is the difference between DD50P564TXLF and DD50P564GTXLF?

A: Both parts are electrically and mechanically identical. The primary differences are packaging format (Tray vs. Bulk) and regulatory compliance status. DD50P564TXLF carries ROHS3 compliance and REACH unaffected designation, while DD50P564GTXLF carries RoHS compliance and REACH affected designation. Selection depends on procurement requirements and regulatory environment.

Q: Does the contact finish difference affect substitution compatibility?

A: The L717DFD50PA specifies 20.0µin (0.51µm) gold contact finish, while DD50P564TXLF and DD50P564GTXLF specify flash gold finish with GXT™ technology. Both finishes provide signal integrity and corrosion resistance within the 300V, 5-7.5A operating envelope. Flash finish thickness is thinner but sufficient for solder termination applications.

Q: Are there thermal limitations when substituting with DD50P564TXLF or DD50P564GTXLF?

A: Yes. The original L717DFD50PA operates from -55°C to 155°C, while both substitute parts operate from -55°C to 125°C. Applications requiring sustained operation above 125°C must use the original L717DFD50PA.

Q: How does backset spacing affect connector selection?

A: Backset spacing is the distance from the connector mounting surface to the contact insertion point. L717DFD50PA specifies 0.319" (8.10mm), while substitutes specify 0.409" (10.40mm). This difference affects PCB layout and mounting bracket design. Verify PCB footprint compatibility before substitution.

Q: What is the significance of GXT™ contact finish on the substitute parts?

A: GXT™ is Amphenol's proprietary gold plating technology applied in flash thickness. It provides enhanced corrosion resistance and signal integrity equivalent to the thicker standard gold finish on the original part, within the specified electrical parameters.

Q: Can packaging format affect connector performance?

A: No. Packaging format (Bag, Tray, Bulk) does not affect electrical or mechanical performance. Selection depends on assembly process requirements and procurement logistics. Tray packaging suits automated assembly, while Bulk packaging supports high-volume manual assembly.

Q: What does RoHS3 compliance mean compared to RoHS compliance?

A: RoHS3 (Directive 2011/65/EU as amended) represents the current regulatory standard for restricted hazardous substances in electrical and electronic equipment. RoHS compliance refers to earlier versions of the directive. Both designations indicate restriction of lead, cadmium, mercury, and other hazardous substances. DD50P564TXLF carries the current RoHS3 designation.
