L717DFD50POL2 Equivalent & Substitute Parts

Part Overview

The L717DFD50POL2 is a 50-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products), configured for panel mount, through-hole solder termination with male pins. This active-status connector is widely used in industrial signal transmission applications. Substitute parts are identified when equivalent electrical and mechanical specifications allow direct interchange within system constraints, supporting supply chain flexibility and application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFD50POL2 is determined by the following critical parameters:

• Connector Type and Position Count: All substitute parts must be 50-position D-Sub plugs with male pins and 3-row configuration (Shell Size 5 / DD, D layout).
• Termination Method: Solder termination is required for direct substitution.
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements. The main part specifies 7.5A and 300V.
• Operating Temperature: The main part operates from -55°C to 125°C; substitute parts must support this range.
• Contact Material and Finish: Brass contacts with gold finish are standard; material and finish compatibility determines interchangeability.
• Compliance and Certification: RoHS compliance status and regulatory certifications affect substitution eligibility in regulated applications.

The identified substitutes vary in mounting approach (through-hole versus panel mount), current ratings, voltage specifications, and compliance certifications, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

L717DFD50POL2: This part is actively manufactured and fully RoHS compliant, meeting regulatory requirements for restricted substance directives. The 7.5A current rating and 300V voltage rating support high-performance industrial applications. The part is REACH unaffected. The panel mount configuration with tin-plated steel shell and machined brass contacts with thicker gold finish (20.0µin) provides robust mechanical and electrical performance for demanding installations.

208010-2: This TE Connectivity substitute shares the core 50-position D-Sub architecture but operates at reduced electrical ratings (6A, 125V) and narrower temperature range (-55°C to 105°C). RoHS non-compliance restricts use in regulated applications. Suitable for applications where lower electrical performance is acceptable and regulatory compliance is not required.

5208010-2: This variant is electrically and functionally identical to 208010-2 but with RoHS compliant status, enabling use in regulated environments. Current rating (6A) and voltage rating (125V) remain below the main part specifications. Temperature range remains -55°C to 105°C.

D50P24A4GV00LF: This Amphenol ICC (FCI) option matches the 300V voltage rating and full temperature range (-55°C to 125°C) of the main part, offering operational compatibility for temperature-critical applications. RoHS compliant and REACH unaffected. The current rating per contact is 5A, lower than the main part. Features include board lock and grounding indents. Phosphor bronze contacts with tin-nickel shell finish provide alternative material compositions for specialized applications.

Frequently Asked Questions (FAQ)

Q: Can 208010-2 or 5208010-2 replace L717DFD50POL2 in all applications?

A: Only in applications where voltage does not exceed 125V and current does not exceed 6A, and where operating temperature remains within the -55°C to 105°C range. These parts are not suitable for systems designed around 300V operation or the full -55°C to 125°C temperature envelope of the main part. Additionally, 208010-2 is RoHS non-compliant and unsuitable for regulated applications.

Q: Is D50P24A4GV00LF a direct replacement for L717DFD50POL2?

A: D50P24A4GV00LF shares voltage rating (300V) and temperature range (-55°C to 125°C), supporting temperature-critical applications. However, the current rating per contact (5A) is lower than the main part (7.5A), requiring verification against actual circuit current requirements. The D50P24A4GV00LF mounting type is through-hole only, without panel mount option. Both parts are RoHS compliant and suitable for regulated environments.

Q: What are the packaging differences between these substitutes?

A: L717DFD50POL2 ships in tray packaging. Substitutes 208010-2 and 5208010-2 use tube packaging. D50P24A4GV00LF uses tray packaging. Tube versus tray packaging affects handling, storage, and automated assembly considerations but does not alter electrical or mechanical specifications.

Q: How do contact finish specifications impact substitution?

A: The main part specifies gold plating at 20.0µin (0.51µm) thickness. All substitutes use gold flash finish with unspecified thickness. Gold flash typically provides thinner coverage than 20.0µin and may affect long-term contact reliability in high-cycle or corrosive environments. Applications with demanding contact resistance or durability requirements should confirm compatibility with flash-plated contacts.

Q: Which substitute parts are suitable for environmentally regulated or RoHS-restricted applications?

A: L717DFD50POL2, 5208010-2, and D50P24A4GV00LF are all RoHS compliant. 208010-2 is RoHS non-compliant and unsuitable for regulated applications. All four parts are classified as HTSUS 8536.69.4040 with ECCN EAR99.
