L17HTNBGPOL2RM54C: Equivalent & Substitute Parts
Part Overview
The L17HTNBGPOL2RM54C is a 25-position D-Sub plug connector with male pins, manufactured by Amphenol ICC (Commercial Products) in the HT series. This through-hole solder-terminated connector is designed for industrial and commercial applications requiring 5A current capability and 600V voltage rating. The connector features a nickel-plated steel shell with gold-plated contacts and includes board lock and grounding indents.
The need to identify equivalent and substitute parts arises from supply chain requirements, application-specific design needs, or when the primary component becomes unavailable. Substitute parts are qualified based on electrical, mechanical, and environmental parameter compatibility.

Engineering Selection Recommendations
Amphenol ICC (FCI) Delta D Series — Preferred Substitutes for Extended Supply Availability: The D25P24 base series (variants A4GV00LF, A4GX00LF, A4PL00LF, A6GV00LF, B4GV00LF, B6GV00LF) from Amphenol ICC (FCI) represents the most direct electrical and mechanical equivalents. All variants maintain 5A current rating, UL94 V-0 compliance, and RoHS Compliant status. Voltage rating of 300V is lower than the primary part's 600V specification; these are suitable for applications not requiring the higher voltage rating. Operating temperature range of -55°C to 125°C provides coverage for most industrial applications, with the primary part offering extended range to 150°C. Select the variant based on flange type requirement: Housing/Shell configuration (A4GX00LF, A4PL00LF) for board-mount applications with threaded fasteners, or Mating Side Female Screwlock (A6GV00LF, B4GV00LF, B6GV00LF) for front-panel or mating-side assembly.
Amphenol ICC (FCI) Series D — Alternative with Different Flange Design: DB25P364TXLF provides 5A current, 300V voltage, and equivalent mechanical footprint. The unthreaded housing/shell design offers simplified board mounting without threaded inserts. Tin plating on shell differs from the nickel-plated finish of the primary part; verify compatibility with environment and mechanical assembly requirements.
HARTING Connectors — Higher Current Capability: Parts 09653216703 (bulk) and 09653616713 (tray) both offer 6.5A current rating and ROHS3 Compliance, with operating temperature range -55°C to 125°C. Voltage rating is not specified for these parts; confirm suitability with application requirements. The mating-side female screwlock flange requires compatible mating housing. Packaging format differs: 09653216703 is bulk, while 09653616713 is supplied in tray format.
TE Connectivity AMPLIMITE HDP-20 Series — Limited Substitution: Part 2-338311-2 meets the 25-position D-Sub configuration and through-hole solder termination. However, the reduced voltage rating of 125V and lower maximum operating temperature of 105°C (compared to the primary part's 150°C) restrict this option to lower-performance applications. Current rating of 6A exceeds the 5A requirement. This part is suitable only where application specifications align with these reduced electrical and thermal parameters.
Active Product Status: All listed substitute parts carry Active product status, confirming current manufacturer support and availability. RoHS and ROHS3 compliance across all options satisfies environmental regulatory requirements for commercial and industrial markets.
Frequently Asked Questions (FAQ)
Q: Can D25P24A6GV00LF be used in place of L17HTNBGPOL2RM54C? D25P24A6GV00LF is electrically compatible for applications not requiring the 600V voltage rating. Both parts maintain 5A current capability, -55°C minimum operating temperature, UL94 V-0 compliance, and 25-position D-Sub configuration. The key difference is that D25P24A6GV00LF is rated to 300V (versus 600V) and operates to 125°C maximum (versus 150°C). If the application requires 600V or operation above 125°C, this substitute is not suitable.
Q: What is the difference between flange types (Housing/Shell vs. Mating Side)? Housing/Shell flange types (M3 or 4-40 threaded fasteners) are mounted to the PCB or enclosure panel with fasteners through the shell. Mating Side Female Screwlock types feature threading on the mating connector interface itself. Select based on assembly method: board-mount applications require Housing/Shell; applications with mating connectors featuring male threads require Mating Side Female Screwlock.
Q: Are HARTING 09653216703 and 09653616713 equivalent to the Amphenol parts? Both HARTING parts meet the 25-position D-Sub male pin, through-hole solder configuration. The 6.5A current rating exceeds the 5A requirement. The key limitation is unspecified voltage rating; these parts cannot be confirmed as 600V-rated equivalents. Confirm HARTING specifications for voltage rating with the manufacturer before substitution in voltage-critical applications. Operating temperature range of -55°C to 125°C is suitable for most industrial environments where 150°C is not required.
Q: What is contact finish thickness, and does it affect substitution? Contact finish thickness (measured in microinches or micrometers) determines gold plating durability under mating cycles and thermal stress. The primary part specifies 30.0µin (0.76µm). Variants with "Flash" thickness are thinner electrodeposits suitable for signal-level applications with lower mating cycle counts. For applications with frequent mating/demating or high reliability requirements, specify parts with 30.0µin thickness (A6GV00LF, B6GV00LF).
Q: Is packaging format (Tray vs. Bulk) a substitution criterion? Packaging format does not affect electrical or mechanical compatibility. Tray packaging (standard tape-and-reel or tray format) is standard for high-volume assembly. Bulk packaging reduces per-unit cost for small-volume applications but requires manual handling and packaging. Both packaging options of the same electrical part number are substitutable.
Q: Can TE Connectivity 2-338311-2 substitute for high-temperature applications? No. The 2-338311-2 maximum operating temperature is 105°C, which is below the primary part's 150°C rating. This part is suitable only for ambient or sealed-enclosure applications not exceeding 105°C. For applications requiring sustained operation above 105°C, specify alternatives from the Amphenol Delta D series or consult additional equivalent options.
