L17HTNEHPOL2RM81C D-Sub Plug 9-Position Vertical Solder Connector

Part Overview

The L17HTNEHPOL2RM81C is a 9-position D-Sub plug connector manufactured by Amphenol ICC (Commercial Products), designed for through-hole solder termination applications. This connector features male pins with a vertical mounting orientation and is classified as an active product with full inventory availability (816 pcs in stock). The HT series connector is widely used in industrial and commercial applications requiring reliable signal transmission across multiple channels.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 9-position D-Sub configuration, male pin plug type, vertical through-hole mounting, solder termination, UL94 V-0 flammability rating, and compatible shell size (DE/E layout). Substitutes maintain functional compatibility while offering alternative contact materials, shell finishes, and flange configurations.

Engineering Selection Recommendations

Primary Substitutes (Solder Termination, Matching Flange Configuration):

The D09P24B6GV00LF and D09P24B4GV00LF (Amphenol ICC FCI, Delta D series) are direct functional equivalents with mating-side female screwlock (4-40) flanges matching the L17HTNEHPOL2RM81C. Both maintain 5A per contact current rating, UL94 V-0 compliance, and RoHS certification. The primary difference is contact finish thickness specification (30.0µin vs. Flash), which does not affect electrical performance in signal applications. Inventory availability is high (1762 pcs and 1403 pcs respectively).

Alternative Flange Configurations (Solder Termination):

The D09P24A4GV00LF and D09P24A4GX00LF provide housing/shell flange options (4-40 and unthreaded respectively) while maintaining identical electrical specifications. These are suitable for applications where mating-side screwlock is not required. The D09P24A4PL00LF offers M3 housing/shell mounting, providing metric fastening compatibility.

Cross-Manufacturer Substitute (HARTING 09651616713):

The HARTING 09651616713 maintains 9-position D-Sub configuration with vertical solder termination and UL94 V-0 rating. It features a higher current rating (6.5A vs. 5A) and ROHS3 compliance. Operating temperature is limited to -55°C to 125°C. This connector is suitable for applications not requiring the full 600V rating of the primary part.

Alternative Termination Method (TE Connectivity 5786830-1):

The TE Connectivity 5786830-1 (AMPLIMITE HD-20 series) uses press-fit termination instead of solder, requiring different PCB pad design. It maintains 9-position D-Sub configuration and UL94 V-0 compliance but operates at a reduced temperature range (-55°C to 105°C). This substitute is applicable only when press-fit termination is acceptable for the application.

Compliance Considerations:

All listed substitutes maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating. The HARTING part carries ROHS3 certification, exceeding standard RoHS requirements. The TE Connectivity part is REACH Affected, while most Amphenol FCI parts are REACH Unaffected. Selection should account for supply chain compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the L17HTNEHPOL2RM81C with a 15-position D-Sub connector?

A: No. The 9-position configuration is a core specification. Substitutes must maintain the same position count and row layout (2 rows) to ensure mechanical and electrical compatibility with mating connectors and PCB footprints.

Q: What is the difference between solder and press-fit termination in D-Sub connectors?

A: Solder termination requires wave or reflow soldering to attach contacts to PCB pads. Press-fit termination uses mechanical insertion into plated through-holes without solder. The TE Connectivity 5786830-1 uses press-fit termination and requires different PCB pad design. Solder-terminated parts (L17HTNEHPOL2RM81C and most substitutes) are not interchangeable with press-fit designs on the same PCB.

Q: Does the contact material difference (Copper Alloy vs. Phosphor Bronze) affect performance?

A: Both materials are acceptable for signal transmission in D-Sub applications. Phosphor Bronze (used in Amphenol FCI Delta D series) offers improved spring characteristics and contact durability. Copper Alloy (used in the primary part and HARTING substitute) provides equivalent electrical performance. Selection depends on application-specific durability requirements and cost considerations.

Q: Why do some substitutes have lower voltage ratings (300V vs. 600V)?

A: The Amphenol FCI Delta D series substitutes are rated for 300V, which is standard for signal-level D-Sub connectors. The primary L17HTNEHPOL2RM81C is rated for 600V, providing additional margin for higher-voltage applications. For signal-only applications, 300V-rated substitutes are fully adequate.

Q: Are there packaging differences between the main part and substitutes?

A: The L17HTNEHPOL2RM81C is supplied in Tray packaging (816 pcs in stock). Most substitutes are also supplied in Tray packaging. The TE Connectivity 5786830-1 is supplied in Bulk packaging. Packaging format does not affect connector performance but may impact procurement and handling procedures.

Q: Can I use the HARTING 09651616713 in applications requiring -55°C to 150°C operation?

A: No. The HARTING part is rated only to 125°C maximum operating temperature, while the primary part operates to 150°C. For applications requiring the full -55°C to 150°C range, use the L17HTNEHPOL2RM81C or select substitutes with matching temperature specifications.

Q: What does "Female Screwlock (4-40)" flange feature mean?

A: This indicates the connector has threaded mounting holes on the mating side (the side that connects to the receptacle) with 4-40 UNC threads. This allows secure mechanical fastening of the plug to the receptacle using 4-40 screws. Alternative flange configurations (Housing/Shell) mount differently and may not be compatible with receptacles designed for mating-side screwlock attachment.

Q: Are all listed substitutes RoHS compliant?

A: Yes. All substitutes listed carry either RoHS or ROHS3 compliance certification. ROHS3 represents an enhanced compliance level. For applications requiring specific RoHS certification levels, verify the substitute's compliance documentation.
