Amphenol ICC L717DFE09PU D-Sub 9-Position Plug Connector

Part Overview

The Amphenol ICC L717DFE09PU is a 9-position D-Sub plug connector with male pins, designed for panel mount through-hole solder termination applications. This connector features a steel tin-plated shell with gold-plated contacts and operates across a temperature range of -55°C to 125°C with a current rating of 7.5A at 300V. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives from different manufacturers that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the L717DFE09PU is determined by the following critical parameters:

Primary Compatibility Criteria:

Connector type: D-Sub plug with male pins
Position count: 9 positions
Shell size and layout: 1 (DE, E)
Termination method: Solder
Flange feature: Housing/Shell configuration
Contact material: Brass with gold finish
Flammability rating: UL94 V-0

Secondary Compatibility Considerations:

Current rating: Minimum 6A (L717DFE09PU rated at 7.5A)
Voltage rating: Minimum 125V (L717DFE09PU rated at 300V)
Operating temperature range: Minimum -55°C to 105°C (L717DFE09PU operates to 125°C)
Mounting configuration: Through-hole solder attachment

Substitute parts are grouped based on whether they maintain these core electrical and mechanical specifications. Parts with reduced current or voltage ratings remain functionally compatible for applications within their specified limits. Differences in shell finish (tin vs. nickel plating), contact finish thickness, and dielectric material do not prevent substitution when other parameters align.

Engineering Selection Recommendations

TE Connectivity AMPLIMITE HD-20 Series (1-5747871-3, 1-5747871-4, 1-5747871-6, 2-5748003-0): These parts are functionally compatible substitutes for through-hole vertical solder applications. All maintain UL94 V-0 flammability rating and brass contact material with gold finish. Current ratings of 6A and voltage ratings of 125V are suitable for applications within these electrical limits. The TE Connectivity parts with ROHS3 or RoHS compliant status are preferred for new designs. Part 1-747871-4 carries RoHS non-compliant status and should be avoided for applications requiring regulatory compliance. Part 1-747871-6 offers ROHS3 compliance with equivalent electrical specifications.

NorComp 172-E Series (172-E09-113R011, 172-E09-113R021, 172-E09-113R911): These parts provide panel mount through-hole compatibility with the L717DFE09PU. All three maintain UL94 V-0 rating and brass contacts with gold finish. Current ratings of 5A and unspecified voltage ratings indicate these parts are suitable for lower-power signal applications. All three carry ROHS3 compliance. Part 172-E09-113R911 includes board lock features in addition to grounding indents. Operating temperature range extends to -50°C minimum, which is acceptable for most applications but does not reach the -55°C lower limit of the main part.

Mounting Configuration Considerations: The L717DFE09PU is specified for panel mount through-hole configuration. TE Connectivity parts 1-5747871-3, 1-5747871-4, 1-5747871-6, and 1-747871-4/6 are specified for through-hole vertical mounting without explicit panel mount designation. NorComp 172-E series parts explicitly support panel mount through-hole configuration, making them more directly equivalent for panel-mounted applications.

Compliance and Regulatory Status: For applications requiring RoHS compliance, avoid part 1-747871-4. All other substitute parts carry either RoHS Compliant or ROHS3 Compliant status. REACH status varies across substitutes; parts with REACH Unaffected status are preferred where regulatory compliance is critical.

Frequently Asked Questions (FAQ)

Q: Can I use a TE Connectivity AMPLIMITE HD-20 part as a direct replacement for the L717DFE09PU in a panel mount application?

A: TE Connectivity AMPLIMITE HD-20 parts (1-5747871-3, 1-5747871-4, 1-5747871-6, 2-5748003-0) are electrically and mechanically compatible for through-hole solder termination. However, these parts are specified for through-hole vertical mounting rather than panel mount configuration. If your application requires panel mount orientation, NorComp 172-E series parts provide explicit panel mount through-hole support and are more directly equivalent.

Q: What is the difference between the TE Connectivity parts with different suffixes (-3, -4, -6)?

A: The suffix designations indicate different flange features and packaging formats. All three maintain identical electrical specifications (6A current, 125V voltage, -55°C to 105°C operating range, UL94 V-0 rating). Differences in RoHS status and REACH compliance exist: 1-5747871-3 and 1-5747871-6 carry ROHS3 compliance, while 1-5747871-4 carries standard RoHS compliance. Part 1-747871-4 is RoHS non-compliant and should be avoided for new designs.

Q: Why do NorComp 172-E series parts have lower current ratings (5A) compared to the L717DFE09PU (7.5A)?

A: Current rating differences reflect design specifications for each connector series. The 5A rating of NorComp parts is suitable for signal-level applications and lower-power circuits. If your application requires the full 7.5A capacity of the L717DFE09PU, TE Connectivity AMPLIMITE HD-20 parts rated at 6A provide closer electrical equivalence, though still below the original specification.

Q: Are there packaging differences between these substitute parts?

A: Yes. The L717DFE09PU is supplied in Tray packaging. TE Connectivity AMPLIMITE HD-20 parts are available in Tube (1-5747871-3, 1-5747871-4, 1-5747871-6) or Bulk (1-747871-4) packaging, with 2-5748003-0 in Tray packaging. NorComp 172-E series parts are supplied in Tray packaging. Packaging format does not affect electrical or mechanical compatibility but may impact procurement and handling procedures.

Q: Can I substitute a part with a lower operating temperature range?

A: NorComp 172-E series parts operate from -50°C to 100°C, compared to the L717DFE09PU range of -55°C to 125°C. Substitution is acceptable only if your application operates within the narrower temperature range. If your design requires operation at -55°C or below, or above 100°C, NorComp parts are not suitable. TE Connectivity AMPLIMITE HD-20 parts operate to -55°C minimum and 105°C maximum, providing better low-temperature coverage but still not reaching the 125°C upper limit of the original part.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: ROHS3 refers to compliance with the third iteration of the Restriction of Hazardous Substances directive. Both RoHS and ROHS3 indicate compliance with hazardous substance restrictions, with ROHS3 representing the current regulatory standard. For new designs, ROHS3 compliant parts are preferred. Part 1-747871-4 is marked as RoHS non-compliant and should not be used in applications subject to RoHS regulations.

Q: Are gold-plated contacts required for substitution?

A: Yes. All listed substitute parts maintain gold contact finish, matching the L717DFE09PU specification. Gold plating provides corrosion resistance and reliable electrical contact performance. This parameter is consistent across all compatible substitutes.
