L17HTNEHPOL2RM51C D-Sub Plug 9-Position Vertical Solder Connector Equivalent & Substitute Parts

Part Overview

The L17HTNEHPOL2RM51C is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products) in the HT series. This through-hole solder-terminated connector features male pins, a 1 (DE, E) shell size layout, and is designed for signal applications with a 5A current rating and 600V voltage rating. The connector is actively produced and RoHS compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: connector style (D-Sub), connector type (plug with male pins), position count (9), row configuration (2 rows), shell size (1/DE/E), mounting type (through-hole), termination method compatibility, and operating temperature range overlap. Substitute parts may vary in shell material finish, contact material, flange feature design, and specific voltage or current ratings within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L17HTNEHPOL2RM51C are grouped based on strict parameter matching in the following categories:

Primary Substitution Criteria (Must Match):

• 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)
• Mounting type: Through-hole
• Termination: Solder
• Material flammability: UL94 V-0
• Product status: Active

Secondary Compatibility Parameters (Allowable Variation):

• Shell material finish: Steel with various plating options (Nickel, Tin-Nickel, Tin)
• Contact material: Copper Alloy or Phosphor Bronze
• Contact finish: Gold (various thicknesses)
• Flange feature: Housing/Shell with different thread types (4-40, M3, Unthreaded) or Mating Side Female Screwlock
• Current rating: 5A to 6.5A per contact
• Voltage rating: 300V to 600V
• Operating temperature: -55°C minimum with upper range from 105°C to 150°C
• Dielectric material: Thermoplastic glass-filled or Polybutylene Terephthalate (PBT)

Excluded from Substitution:

• Press-fit termination (5786830-1 excluded due to termination method difference)
• HARTING 09651616713 excluded due to mating-side screwlock flange feature incompatibility with housing-shell mounting

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC (FCI) Delta D Series Substitutes (D09P24 Base Family):

All Delta D series parts listed (D09P24A4GV00LF, D09P24A4GX00LF, D09P24A4PA00LF, D09P24A4PL00LF, D09P24A6GV00LF, D09P24B4GV00LF, D09P24B4GX00LF, D09P24B6GV00LF) are direct functional equivalents to the L17HTNEHPOL2RM51C. These parts share identical core specifications: 9-position D-Sub plug configuration, through-hole solder termination, UL94 V-0 flammability rating, and RoHS compliance.

Differences between these substitutes relate to flange feature design (Housing/Shell with 4-40 threads, M3 threads, or Unthreaded; Mating Side Female Screwlock) and contact material composition (Phosphor Bronze vs. Copper Alloy). The voltage rating of 300V on Delta D series is lower than the 600V rating of the main part; however, this represents a conservative design margin for most signal-level applications. Operating temperature upper limit of 125°C on Delta D series is lower than the 150°C specification of the main part.

Selection among Delta D variants depends on specific flange mounting requirements and PCB layout constraints. Parts with Housing/Shell (4-40) flange feature (D09P24A4GX00LF, D09P24B4GX00LF) provide direct mechanical compatibility with the main part's flange design.

Excluded Substitutes:

The HARTING 09651616713 connector is excluded due to mating-side female screwlock flange feature, which differs from the housing-shell mounting interface of the L17HTNEHPOL2RM51C.

The TE Connectivity 5786830-1 (AMPLIMITE HD-20 series) is excluded due to press-fit termination method, which is incompatible with solder-terminated applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute a Delta D series part (D09P24 family) for the L17HTNEHPOL2RM51C in my application?

A: Delta D series parts are functionally equivalent for 9-position D-Sub plug applications with solder termination and through-hole mounting. Verify that your application can operate within the 300V voltage rating and -55°C to 125°C temperature range of the Delta D series. Confirm flange feature compatibility with your PCB mounting holes.

Q: What is the difference between Housing/Shell (4-40) and Mating Side Female Screwlock flange features?

A: Housing/Shell (4-40) flange features provide threaded mounting points on the connector shell itself, suitable for panel or PCB mounting with 4-40 screws. Mating Side Female Screwlock features provide threaded receptacles on the mating interface side, used for cable-to-connector assembly. Select based on your specific mounting and mating requirements.

Q: Why does the L17HTNEHPOL2RM51C have a 600V rating while Delta D substitutes are rated 300V?

A: Voltage rating differences reflect design specifications for different application classes. The 300V rating of Delta D series is suitable for standard signal-level applications. If your application requires 600V isolation or operates at voltages above 300V, the L17HTNEHPOL2RM51C is the appropriate choice.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS compliant. The main part L17HTNEHPOL2RM51C is RoHS compliant. Verify REACH status for your specific supply chain requirements; some parts are marked as REACH Affected or REACH Unaffected.

Q: What is the difference between Nickel Plated and Tin-Nickel Plated shell finishes?

A: Nickel plating provides corrosion resistance and is the finish on the main part. Tin-Nickel plating on Delta D series provides enhanced corrosion resistance and improved solderability. Both finishes are suitable for solder-terminated applications; Tin-Nickel may offer superior performance in high-humidity or corrosive environments.

Q: Can I use a press-fit terminated connector like the TE Connectivity 5786830-1 as a substitute?

A: No. The 5786830-1 uses press-fit termination, which is mechanically and electrically incompatible with solder-terminated applications. Press-fit connectors require different PCB pad designs and assembly processes. Use only solder-terminated equivalents.

Q: What packaging options are available for substitute parts?

A: The main part L17HTNEHPOL2RM51C is supplied in Tray packaging. Most Delta D series substitutes are also supplied in Tray packaging. The TE Connectivity 5786830-1 is supplied in Bulk packaging but is excluded due to termination method incompatibility.
