L77DFE09POL2 D-Sub 9-Position Plug Connector – Equivalent & Substitute Parts

Part Overview

The L77DFE09POL2 is a 9-position D-Sub plug connector manufactured by Amphenol ICC, featuring male pins, panel mount through-hole termination, and solder attachment. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part operates across a temperature range of -55°C to 155°C with a 7.5A current rating and 300V voltage rating, meeting UL94 V-0 flammability requirements and RoHS compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following parameters: connector style (D-Sub), connector type (plug with male pins), number of positions (9), number of rows (2), shell size and layout (1 / DE, E), termination method (solder), and material flammability rating (UL94 V-0). All substitute parts listed maintain these core electrical and mechanical characteristics.

Amphenol ICC L717DFE09POL2 qualifies as a manufacturer-recommended direct substitute, sharing identical position count, shell size, termination, and flammability rating. HARTING and TE Connectivity alternatives provide functional equivalence within the D-Sub 9-position plug category, though with variations in mounting configuration, contact finish, and operating temperature ranges that must be evaluated for specific application requirements.

Engineering Selection Recommendations

Primary Recommendation: L717DFE09POL2 (Amphenol ICC)

The L717DFE09POL2 is the manufacturer-recommended substitute for the obsolete L77DFE09POL2. Both parts share identical connector specifications, shell size, position count, and termination method. The L717DFE09POL2 maintains active product status with equivalent electrical performance and RoHS compliance. The primary operational difference is the maximum temperature rating, which decreases from 155°C to 125°C. This part is suitable for applications where the original L77DFE09POL2 was specified and temperature operation does not exceed 125°C.

Secondary Recommendations: HARTING 9-Position D-Sub Plugs

HARTING offers multiple 9-position D-Sub plug alternatives (09641227240, 09651216703, 09651217703, 09651296703, 09651696713) with active product status and ROHS3 compliance. These parts maintain the required shell size, position count, and solder termination. Current ratings range from 6.5A to 7.5A, and operating temperatures span -55°C to 125°C. Mounting configurations vary between panel mount and through-hole options. Selection depends on specific flange feature requirements and contact finish specifications for the target application.

Tertiary Recommendations: TE Connectivity AMPLIMITE Series

TE Connectivity provides D-Sub 9-position plug alternatives within the AMPLIMITE HD-20 and HDP-20 series (1-338309-2, 1-5747871-3, 1-5747871-4, 1-5747871-6). These connectors maintain the required shell size and position count with solder termination. Current ratings are 6A, and operating temperatures range from -55°C to 105°C. All parts carry active product status and RoHS or ROHS3 compliance. These options are suitable for applications where the lower maximum temperature rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can L717DFE09POL2 directly replace L77DFE09POL2 in all applications?

A: L717DFE09POL2 is electrically and mechanically compatible with L77DFE09POL2 for applications operating at or below 125°C. The original part supports operation to 155°C. If your application requires sustained operation above 125°C, alternative substitutes must be evaluated or the original part sourced from inventory.

Q: What is the primary difference between Amphenol ICC and HARTING 9-position D-Sub plugs?

A: Both manufacturers provide 9-position D-Sub plugs with identical shell size and position count. Key differences include mounting configuration (panel mount versus through-hole), contact material composition, and operating temperature ranges. HARTING parts offer through-hole mounting, while the Amphenol ICC L717DFE09POL2 maintains panel mount capability. Current ratings and contact finish specifications also vary by model.

Q: Are all listed substitutes RoHS compliant?

A: All substitute parts listed carry either RoHS or ROHS3 compliance status. The original L77DFE09POL2 is RoHS Compliant. HARTING and TE Connectivity alternatives are ROHS3 Compliant, which represents an updated regulatory standard. Both compliance levels are acceptable for new designs and legacy system support.

Q: What is the significance of current rating differences among substitutes?

A: The original L77DFE09POL2 supports 7.5A continuous current. Substitute parts range from 6A to 7.5A. Current rating determines the maximum continuous current the connector can safely carry without exceeding temperature limits. Applications requiring 7.5A should prioritize L717DFE09POL2 or HARTING 09641227240. Applications with lower current requirements can utilize alternatives with 6A or 6.5A ratings.

Q: How do operating temperature ranges affect substitution decisions?

A: The original L77DFE09POL2 operates from -55°C to 155°C. Substitute parts operate within -20°C to 125°C ranges. If your application requires sustained operation above 125°C, the L717DFE09POL2 or HARTING alternatives may not be suitable. Verify the maximum operating temperature requirement before selecting a substitute part.

Q: What packaging options are available for substitute parts?

A: Substitute parts are supplied in Tray, Tube, or Bulk packaging. L717DFE09POL2 is supplied in Tray packaging. HARTING parts are available in Tray or Bulk. TE Connectivity AMPLIMITE series parts are supplied in Tube packaging. Packaging selection does not affect electrical or mechanical compatibility; it addresses inventory and handling requirements only.
