L717DFDG50PAM4 Equivalent & Substitute Parts

Part Overview

The L717DFDG50PAM4 is a 50-position D-Sub plug connector manufactured by Amphenol ICC, featuring male pins, right-angle mounting, and solder termination. This connector is designed for panel mount and through-hole applications requiring signal transmission in industrial and commercial environments. The part is currently active in production with 973 units in stock inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFDG50PAM4 is determined by strict alignment with the following parameters:

Critical Parameters (Must Match):

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 50
• Number of rows: 3
• Shell size/connector layout: 5 (DD, D)
• Mounting type: Panel Mount, Through Hole, Right Angle
• Termination method: Solder
• Contact type: Signal
• Material flammability rating: UL94 V-0

Allowable Variations:

• Shell material finish (Steel Tin Plated vs. Steel Nickel Plated)
• Contact finish thickness (20.0µin vs. Flash)
• Flange feature configuration (Board Side vs. Housing/Shell vs. Mating Side)
• Current rating (7.5A vs. 5A)
• Backset spacing (0.319" vs. 0.370")
• Operating temperature range (-55°C ~ 125°C vs. -50°C ~ 100°C)
• Color (Black vs. White)
• Compliance variants (RoHS Compliant vs. ROHS3 Compliant)

The substitute parts 174-E50-113R001 and 174-E50-113R141 (both NorComp Inc.) satisfy all critical parameters while presenting acceptable variations in secondary characteristics.

Engineering Selection Recommendations

Primary Part: L717DFDG50PAM4

Select this part when:

• Operating temperature range of -55°C to 125°C is required
• Current rating of 7.5A per contact is specified
• Backset spacing of 0.319" (8.10mm) is required
• Board-side M3 flange mounting is specified
• Tin-plated steel shell finish is preferred
• Contact finish thickness of 20.0µin is required

Substitute Part: 174-E50-113R001 (NorComp Inc.)

Select this part when:

• Operating temperature range of -50°C to 100°C is acceptable
• Current rating of 5A per contact is sufficient
• Backset spacing of 0.370" (9.40mm) is acceptable
• Housing/shell unthreaded flange configuration is acceptable
• Nickel-plated steel shell finish is acceptable
• Flash contact finish thickness is acceptable
• ROHS3 compliance is required

Substitute Part: 174-E50-113R141 (NorComp Inc.)

Select this part when:

• Operating temperature range of -50°C to 100°C is acceptable
• Current rating of 5A per contact is sufficient
• Backset spacing of 0.370" (9.40mm) is acceptable
• Mating-side female screwlock (4-40) flange configuration is required
• Nickel-plated steel shell finish is acceptable
• Flash contact finish thickness is acceptable
• ROHS3 compliance is required
• Mounting bracket features are required

All three parts maintain active product status, UL94 V-0 flammability rating, REACH unaffected status, and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can 174-E50-113R001 be used as a direct replacement for L717DFDG50PAM4?

A: 174-E50-113R001 is functionally compatible for applications where the operating temperature range of -50°C to 100°C is acceptable and current requirements do not exceed 5A per contact. The backset spacing difference (0.370" vs. 0.319") and flange feature variation (Housing/Shell unthreaded vs. Board Side M3) must be evaluated against specific PCB layout and mounting requirements.

Q: What is the primary difference between 174-E50-113R001 and 174-E50-113R141?

A: Both parts are manufactured by NorComp Inc. and share identical electrical and mechanical specifications. The primary difference is the flange feature: 174-E50-113R001 has an unthreaded housing/shell flange, while 174-E50-113R141 features a mating-side female screwlock (4-40) flange with mounting brackets. Selection depends on the specific mounting and locking requirements of the application.

Q: Are there temperature limitations when substituting with NorComp parts?

A: Yes. The L717DFDG50PAM4 operates from -55°C to 125°C, while both NorComp substitute parts operate from -50°C to 100°C. Applications requiring operation below -50°C or above 100°C must use the original L717DFDG50PAM4 part.

Q: What is the impact of the current rating difference?

A: The L717DFDG50PAM4 is rated for 7.5A per contact, while NorComp substitutes are rated for 5A per contact. Applications requiring current transmission exceeding 5A per contact must use the original Amphenol ICC part.

Q: How do the backset spacing differences affect compatibility?

A: Backset spacing (0.319" for L717DFDG50PAM4 vs. 0.370" for NorComp parts) determines the distance from the connector mounting surface to the contact plane. This dimension is critical for PCB layout and mating connector alignment. Substitution is only valid if the receiving connector or mating device accommodates the 0.370" spacing.

Q: Are all three parts RoHS compliant?

A: Yes. The L717DFDG50PAM4 is RoHS Compliant, while both NorComp parts are ROHS3 Compliant. Both compliance levels satisfy RoHS requirements for new designs and applications.

Q: What packaging format is used for all three parts?

A: All three parts are supplied in tray packaging. Inventory availability: L717DFDG50PAM4 (973 units), 174-E50-113R001 (805 units), 174-E50-113R141 (722 units).
