Engineering Selection Recommendations
Primary Substitutes (Highest Compatibility):
The Amphenol ICC (FCI) Delta D series parts D25P24A4GX00LF, D25P24A4GV00LF, D25P24A6GV00LF, D25P24B4GV00LF, and D25P24B6GV00LF are direct functional equivalents to the L17HTNBHPOL2RM54C. These parts share the same manufacturer family (Amphenol ICC), identical connector geometry, and equivalent electrical performance. All Delta D series substitutes are RoHS compliant, whereas the main part is RoHS non-compliant. The Delta D series operates at -55°C to 125°C, which covers the lower portion of the main part's temperature range. For applications requiring operation above 125°C, the main part L17HTNBHPOL2RM54C is required.
Secondary Substitutes (Acceptable with Application Review):
The HARTING parts 09653216703 and 09653616713 are mechanically and electrically compatible. Both feature higher current ratings (6.5A) and are ROHS3 compliant. The 09653616713 includes Board Lock and Grounding Indents features matching the main part. Operating temperature is limited to -55°C to 125°C. Voltage rating is not specified for HARTING parts; applications requiring the 600V rating of the main part should confirm HARTING specifications independently.
The TE Connectivity 2-338311-2 (AMPLIMITE HDP-20 series) is mechanically compatible but has reduced voltage rating (125V) and lower maximum operating temperature (105°C). This part is suitable only for applications within these electrical and thermal constraints.
RoHS Compliance Consideration:
The main part L17HTNBHPOL2RM54C is RoHS non-compliant. All listed substitute parts are RoHS compliant (RoHS3 or RoHS Compliant status). Selection of substitute parts provides regulatory compliance advantage for new designs or applications subject to RoHS requirements.
Frequently Asked Questions (FAQ)
Q: Can D25P24A4GX00LF replace L17HTNBHPOL2RM54C in all applications?
A: D25P24A4GX00LF is mechanically and electrically compatible for applications operating within -55°C to 125°C and 300V maximum. The main part operates to 150°C and 600V. For applications requiring operation above 125°C or above 300V, the main part is required. Both parts share identical 25-position, 2-row D-Sub geometry, through-hole solder termination, and UL94 V-0 flammability rating.
Q: What is the difference between Housing/Shell and Mating Side flange configurations?
A: Flange feature refers to the mounting interface. Housing/Shell flanges mount on the connector shell itself, typically using 4-40 or M3 threaded holes. Mating Side flanges mount on the mating connector side with female screwlock features. Both configurations are mechanically compatible with standard D-Sub receptacles. Selection depends on the specific mounting requirements of the application.
Q: Are HARTING parts 09653216703 and 09653616713 interchangeable?
A: Both HARTING parts are mechanically and electrically compatible. The primary difference is packaging (Bulk versus Tray) and features. Part 09653616713 includes Board Lock and Grounding Indents, matching the main part's feature set. Part 09653216703 includes only Grounding Indents. For applications requiring board lock functionality, 09653616713 is the appropriate selection.
Q: Why does the main part have a 600V rating while most substitutes are rated 300V?
A: Voltage rating is determined by dielectric material composition and spacing geometry. The main part L17HTNBHPOL2RM54C uses Thermoplastic Glass Filled dielectric rated for 600V. Most substitute parts use Polybutylene Terephthalate (PBT) dielectric rated for 300V. For applications requiring 600V operation, the main part or equivalent high-voltage rated alternatives must be selected.
Q: Can I use TE Connectivity 2-338311-2 as a substitute?
A: The TE Connectivity 2-338311-2 is mechanically compatible but has reduced electrical ratings. Maximum voltage is 125V (versus 600V for the main part) and maximum operating temperature is 105°C (versus 150°C). This part is suitable only for applications within these constraints. For general-purpose applications matching the main part's full electrical specification, Amphenol FCI Delta D series parts are recommended.
Q: What is the significance of Contact Finish Thickness specifications?
A: Contact finish thickness affects durability and wear resistance. The main part specifies 30.0µin (0.76µm) gold plating. Some substitute parts specify "Flash" thickness, which is thinner. Both thicknesses provide adequate corrosion resistance and electrical conductivity for signal applications. Flash thickness is acceptable for standard signal connector applications; thicker plating may be required for high-cycle mating applications.
Q: Are all listed substitutes available in Tray packaging?
A: Packaging varies by part. The main part L17HTNBHPOL2RM54C is supplied in Tray. Most Amphenol FCI Delta D series substitutes are available in Tray packaging. HARTING part 09653216703 is supplied in Bulk; 09653616713 is supplied in Tray. TE Connectivity 2-338311-2 is supplied in Bulk. Verify packaging availability with supplier for production requirements.
Q: What does RoHS compliance mean for connector selection?
A: RoHS (Restriction of Hazardous Substances) compliance restricts use of lead, cadmium, mercury, and other hazardous materials. The main part is RoHS non-compliant, indicating it may contain restricted substances. All listed substitutes are RoHS compliant (RoHS3 or RoHS Compliant), meeting current regulatory requirements for electronics manufacturing in the EU and other regions. New designs should specify RoHS-compliant parts.
