L717DFD50POL2RM8 Equivalent & Substitute Parts

Part Overview

The L717DFD50POL2RM8 is a 50-position D-Sub plug connector manufactured by Amphenol ICC with panel mount, through-hole solder termination. The product is active and stocked with 906 pieces in inventory. Alternative connector models are necessary when panel mount configurations are unavailable, when RoHS compliance requirements differ, or when specific electrical ratings must align with system design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFD50POL2RM8 is determined by the following critical parameters:

• Connector Type: Plug, Male Pins (both substitute parts match)
• Position Count: 50 positions (both substitute parts match)
• Number of Rows: 3 rows (both substitute parts match)
• Shell Size: 5 (DD, D) (both substitute parts match)
• Contact Type: Signal (both substitute parts match)
• Termination Method: Solder (both substitute parts match)
• Mounting Type: Through Hole capability (main part is panel mount/through hole; substitutes are through hole only)

The substitute parts 208010-2 and 5208010-2 share identical connector geometry, position configuration, and solder termination with the L717DFD50POL2RM8. However, both substitutes use vertical orientation and remove the panel mount feature. Both are manufactured by TE Connectivity AMP Connectors in the AMPLIMITE HD-20 series.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5208010-2

The 5208010-2 is the preferred substitute for the L717DFD50POL2RM8 when mounting orientation requirements permit vertical through-hole configuration. This part maintains RoHS compliance, matches the flammability rating, and provides identical positional density and contact material. Availability is high with 1,270 pieces in stock.

Secondary Substitute: 208010-2

The 208010-2 provides identical connector geometry and positional configuration with the same current and voltage ratings as 5208010-2. However, this part does not meet RoHS compliance requirements. Selection of 208010-2 is limited to applications where RoHS exemptions are applicable or where legacy equipment requirements specify this connector variant.

Design Considerations

Both substitute parts operate at reduced maximum voltage (125V versus 300V) and reduced current capacity (6A versus 7.5A) compared to the L717DFD50POL2RM8. System designs must verify that actual operating parameters remain within these reduced ratings. The maximum operating temperature is reduced from 155°C to 105°C, which eliminates substitutes for high-temperature applications requiring the full -55°C to 155°C range.

The L717DFD50POL2RM8 panel mount feature is not available in either substitute. Applications requiring panel-mount connection require the original Amphenol ICC part or alternative panel-mount solutions from other manufacturers.

Frequently Asked Questions (FAQ)

Q: Can 5208010-2 directly replace L717DFD50POL2RM8 in existing designs?

A: Mechanical and electrical compatibility exists for the connector interface only. The 5208010-2 uses vertical through-hole mounting rather than panel mount, eliminating the panel retention feature of the original part. Designs must accommodate vertical orientation or implement alternative mechanical mounting. System voltage and current ratings must remain within 125V and 6A limits respectively.

Q: Why are the voltage and current ratings lower on the substitute parts?

A: The 208010-2 and 5208010-2 represent different connector series (AMPLIMITE HD-20) manufactured by TE Connectivity with different electrical specifications than the Amphenol ICC DF series. The lower ratings reflect design differences between manufacturers and series, not interchangeability limitations.

Q: What is the impact of RoHS compliance differences?

A: The 208010-2 is RoHS non-compliant while the original L717DFD50POL2RM8 and 5208010-2 are RoHS compliant. Applications requiring RoHS certification or deployed in jurisdictions with RoHS restrictions must use either the original part or the 5208010-2.

Q: Are the connector pin configurations identical?

A: Both substitute parts maintain identical 50-position, 3-row pin configuration in the 5 (DD, D) shell size. Pin assignment compatibility depends on the original design; no pin remapping is required for mechanical fit.

Q: How does the contact finish difference affect performance?

A: All three parts feature gold contact plating. The main part specifies 20.0µin (0.51µm) thickness while the substitutes specify flash thickness. Both finishes provide corrosion resistance and low contact resistance suitable for signal transmission in D-Sub applications.

Q: What is the practical inventory advantage?

A: The 5208010-2 offers the highest inventory availability with 1,270 pieces in stock, compared to 906 pieces for the original and 1,164 pieces for the 208010-2, providing supply continuity advantages for high-volume procurement.
