Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L717DFD50PAM4B are identified based on strict alignment with the following critical parameters:

• Connector Style & Type: D-Sub plug with male pins
• Position Count & Row Configuration: 50 positions, 3 rows
• Shell Size: Size 5 (DD, D layout)
• Mounting Configuration: Right-angle, through-hole compatible
• Termination Method: Solder
• Voltage & Temperature Ratings: 300V minimum, operating range compatibility
• Compliance Standards: UL94 V-0 flammability, RoHS compliance

The substitute parts DD50P564TXLF and DD50P564GTXLF meet these core substitution criteria. Variations in current rating, backset spacing, contact finish thickness, and operating temperature maximum do not preclude substitution when the application requirements fall within the substitute part specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: L717DFD50PAM4B

Use the L717DFD50PAM4B when the application requires:

• Operating temperatures up to 155°C
• Current capacity of 7.5A per contact
• Backset spacing of 0.590" (14.99mm)
• Panel mount configuration with commercial-grade specifications

Substitute Part: DD50P564TXLF

DD50P564TXLF is suitable as a substitute when:

• Operating temperature maximum of 125°C is acceptable
• Current requirement does not exceed 5A per contact
• Backset spacing of 0.409" (10.40mm) is compatible with PCB layout
• ROHS3 compliance is required
• Tray packaging is preferred
• Higher inventory availability (1219 units) supports procurement needs

Substitute Part: DD50P564GTXLF

DD50P564GTXLF is suitable as a substitute when:

• Operating temperature maximum of 125°C is acceptable
• Current requirement does not exceed 5A per contact
• Backset spacing of 0.409" (10.40mm) is compatible with PCB layout
• RoHS compliance (non-ROHS3) is acceptable
• Bulk packaging is acceptable
• REACH unaffected status is required

All three parts share identical connector style, position count, row configuration, shell size, mounting type, termination method, voltage rating, flammability rating, and MSL classification. Selection between parts depends on application-specific requirements for temperature range, current capacity, backset spacing, packaging format, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can DD50P564TXLF replace L717DFD50PAM4B in all applications?

A: DD50P564TXLF is a functional substitute when the application operates within -55°C to 125°C and current per contact does not exceed 5A. The backset spacing difference (0.409" vs. 0.590") requires PCB layout verification. Panel mount capability is not specified for DD50P564TXLF; confirm mounting requirements before substitution.

Q: What is the difference between DD50P564TXLF and DD50P564GTXLF?

A: Both parts are mechanically and electrically identical. The primary differences are packaging format (DD50P564TXLF in tray, DD50P564GTXLF in bulk) and regulatory compliance status (DD50P564TXLF is ROHS3 compliant and REACH unaffected; DD50P564GTXLF is RoHS compliant and REACH affected).

Q: Why does L717DFD50PAM4B have a higher current rating than the substitute parts?

A: Current rating differences reflect design variations in contact material and geometry. L717DFD50PAM4B uses brass contacts rated at 7.5A, while DD50P564TXLF and DD50P564GTXLF use copper alloy contacts rated at 5A per contact. Application current requirements determine which part is appropriate.

Q: Are there mechanical compatibility issues between these parts?

A: Backset spacing differs between the main part (0.590") and substitute parts (0.409"). This affects PCB hole pattern and mounting hole alignment. Verify PCB design compatibility before substitution. Shell size, connector layout, and pin configuration are identical across all three parts.

Q: Which part should be selected for new designs?

A: For new designs, specify based on application requirements: temperature range, current per contact, backset spacing compatibility, and packaging preference. All three parts meet the same voltage, flammability, and MSL standards. Regulatory compliance requirements (RoHS vs. ROHS3, REACH status) may influence selection for specific markets.

Q: Is the contact finish difference significant?

A: L717DFD50PAM4B specifies 20.0µin (0.51µm) gold plating, while substitute parts specify flash gold plating with GXT™ treatment. Both finishes provide corrosion resistance and electrical conductivity suitable for signal applications. Flash plating is thinner but adequate for the specified voltage and current ratings.
