L17HTNEHPOL2RM84C D-Sub Plug 9 Position Vertical Solder Connector

Part Overview

The L17HTNEHPOL2RM84C 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 with a mating-side female screwlock (4-40) flange and is designed for signal applications. The connector is actively produced and RoHS compliant, with 835 units currently in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications permit selection from functionally compatible alternatives within the same connector category and electrical parameters.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The following parts are recommended as primary substitutes based on active product status and full RoHS compliance:

D09P24A6GV00LF (Amphenol ICC FCI, Delta D series): Highest inventory availability (20,199 units). Matches mating-side female screwlock flange configuration. Solder termination. Operating temperature -55°C to 125°C. Voltage rating 300V is lower than primary part but acceptable for most applications. Contact finish 30.0µin (0.76µm) gold matches primary specification.
D09P24B4GV00LF (Amphenol ICC FCI, Delta D series): Active status with 1,403 units in stock. Identical flange configuration (mating side, female screwlock 4-40). Solder termination. 5A current rating matches primary part. Operating temperature -55°C to 125°C.
D09P24A4GV00LF (Amphenol ICC FCI, Delta D series): Active status with 1,202 units. Mating-side female screwlock flange. Solder termination. 5A current rating. Operating temperature -55°C to 125°C.
6-338309-2 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20): Active status with 876 units. Solder termination. 6A current rating exceeds primary specification. Housing/shell flange with 4-40 threading. Operating temperature -55°C to 105°C.

Termination Variation (Press-Fit Alternative):

5786830-1 (TE Connectivity AMP Connectors, AMPLIMITE HD-20): Active status with 1,718 units. Press-fit termination differs from solder requirement of primary part. Use only when PCB design accommodates press-fit contact installation. Housing/shell flange with 4-40 threading.

Frequently Asked Questions (FAQ)

Q: Can D09P24A6GV00LF replace L17HTNEHPOL2RM84C directly?

A: Yes. Both are 9-position D-Sub plugs with male pins, through-hole mounting, solder termination, and mating-side female screwlock (4-40) flanges. Both are RoHS compliant with UL94 V-0 flammability rating and MSL 1. The primary difference is voltage rating: D09P24A6GV00LF is rated 300V versus 600V for L17HTNEHPOL2RM84C. This substitution is valid for applications operating at or below 300V.

Q: What is the difference between mating-side female screwlock and housing/shell flange configurations?

A: Mating-side female screwlock (4-40) places threaded holes on the connector face for mating with a receptacle. Housing/shell flange configurations vary: unthreaded shells provide no threaded interface, while 4-40 threaded housing shells provide threaded holes on the shell body. Flange configuration affects mechanical mounting and mating interface design. Selection depends on PCB layout and mating connector design.

Q: Why does 5786830-1 have press-fit termination instead of solder?

A: Press-fit termination uses spring-loaded contacts that compress into plated PCB holes without solder. This differs from solder termination, which requires thermal attachment to PCB pads. Press-fit termination is not interchangeable with solder termination unless PCB design is modified to accommodate press-fit contact geometry and hole specifications.

Q: Is the HARTING 09651616713 equivalent to the primary part?

A: The HARTING 09651616713 matches all critical parameters: 9-position D-Sub plug, male pins, through-hole solder termination, mating-side female screwlock (4-40) flange, UL94 V-0 rating, and MSL 1. Current rating is 6.5A, exceeding the 5A primary specification. Operating temperature range is -55°C to 125°C, which is 25°C lower than the primary part. This substitution is valid for applications within the -55°C to 125°C range.

Q: What does "obsolete" product status mean for 5-338309-2?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available from distributors, but no new production is planned. Use obsolete parts only when active alternatives are unavailable or when design constraints require this specific part number. Verify long-term availability before committing to designs using obsolete components.

Q: Can I substitute a Delta D series connector for the HT series primary part?

A: Yes, provided all electrical and mechanical parameters match. Delta D series parts (D09P24 base number) are functionally equivalent to the HT series L17HTNEHPOL2RM84C when they share identical position count, termination type, flange configuration, and operating specifications. Series designation indicates product line but does not prevent cross-series substitution when parameters align.

Q: What is the significance of contact finish thickness specification?

A: Contact finish thickness (measured in microinches or micrometers) determines durability and wear resistance. The primary part specifies 30.0µin (0.76µm) gold finish. D09P24A6GV00LF matches this specification exactly. Parts without specified thickness may use flash plating (minimal thickness) or standard plating. Flash plating is acceptable for equivalent electrical performance but may have reduced wear life in high-cycle mating applications.

Q: Are all listed substitutes RoHS compliant?

A: Yes. All substitute parts listed carry either RoHS Compliant or ROHS3 Compliant status. ROHS3 represents the current RoHS 2.0 directive compliance standard. Both designations meet current regulatory requirements for lead-free and restricted substance compliance.

Q: What packaging format differences exist among substitutes?

A: The primary part L17HTNEHPOL2RM84C is packaged in Tray format. Most Delta D series substitutes (D09P24 variants) are also Tray packaged. TE Connectivity parts 5786830-1 and 6-338309-2 are Bulk packaged. Packaging format affects handling, storage, and component presentation but does not affect electrical or mechanical function. Verify packaging compatibility with assembly equipment before selection.
