Engineering Selection Recommendations

Primary Design Replacement (RoHS3 Compliance Required):

2-338315-2 and 6-338315-2 (TE Connectivity AMP AMPLIMITE series) are suitable direct replacements when RoHS3 compliance is mandatory. Both parts maintain solder termination, meet current and voltage specifications, and are active products. Select 2-338315-2 for standard applications or 6-338315-2 for REACH-affected regulations.

Alternative Termination Method (Press-Fit Assembly):

5745922-2 (TE Connectivity AMPLIMITE HD-20) provides press-fit termination instead of solder, reducing thermal stress during assembly while maintaining RoHS3 compliance and UL94 V-0 flammability rating.

High-Temperature Operation (Extended Range):

The L17HTNBGSOL2RM81C retains superiority for thermal applications requiring sustained operation to 150°C. No substitute part in this list extends beyond 125°C.

High-Reliability Amphenol Alternatives:

D25S24A4GL00LF, D25S24A4GX00LF, D25S24A6GV00LF, D25S24A6GX00LF, and D25S24B4GV00LF (Delta D series, Amphenol ICC/FCI) offer RoHS compliance with tin-nickel plating and phosphor bronze contacts. These parts are active products with board lock features and suit high-reliability applications.

Multi-Manufacturer Availability:

09663516513 (Harting) provides a ROHS3-compliant option with enhanced current capacity (6.5A) and an alternative manufacturing source for supply chain redundancy.

Frequently Asked Questions (FAQ)

Q: What makes these parts interchangeable with the L17HTNBGSOL2RM81C? A: All substitute parts maintain the core mechanical and electrical specifications: 25-position D-Sub receptacle configuration, Shell Size 3 (DB, B), through-hole mounting, female socket contact arrangement, and UL94 V-0 flammability rating. Current ratings range from 5A to 6.5A and voltage ratings from 300V to 600V, satisfying minimum application requirements.

Q: Why would I select a substitute if the original part is in stock? A: Substitution is driven by regulatory compliance (RoHS3/REACH requirements), operating temperature constraints, assembly process compatibility (solder vs. press-fit), supply chain continuity, or cost optimization across equivalent performance levels.

Q: Are there differences in flange fastening options? A: Yes. The main part features mating-side female screwlock (M3). Substitutes offer variations including housing-mounted fastening with M3, 4-40 threading, or unthreaded designs. Match the flange type to your PCB layout and enclosure interface requirements.

Q: What is the impact of shell finish differences (nickel vs. tin vs. tin-nickel)? A: Shell finish affects corrosion resistance and EMI shielding characteristics. Nickel-plated finishes (original part) provide superior corrosion resistance; tin-plated finishes offer cost efficiency; tin-nickel combinations balance both properties. All finishes are compatible with standard PCB assembly processes.

Q: Can I substitute a press-fit connector (5745922-2) for a solder connector (L17HTNBGSOL2RM81C)? A: Press-fit termination eliminates solder reflow steps but requires compatible through-hole pad sizing and insertion tooling. Mechanical compatibility is confirmed, but assembly process validation is required for your specific PCB design.

Q: Why do some parts list RoHS status differently (RoHS non-compliant, ROHS3, RoHS Compliant)? A: RoHS directives have evolved in scope. Parts marked "RoHS non-compliant" predate or fall outside the original directive; "RoHS Compliant" indicates EU 2002/95/EC compliance; "ROHS3 Compliant" meets the current EU 2011/65/EU standard. Select ROHS3 parts for new designs targeting current regulatory markets.

Q: Are operating temperature ranges limiting factors in substitution? A: The original part operates to 150°C, while most substitutes are limited to 105°C–125°C. For thermal applications near or above 125°C, the L17HTNBGSOL2RM81C remains the only suitable option in this comparison set.

Q: What contact material differences matter? A: Copper Alloy contacts (original, Harting, TE Connectivity 5745922-2) and Phosphor Bronze contacts (Amphenol Delta D series) are both UL-rated. Phosphor Bronze provides enhanced spring force retention in high-cycle mating environments; Copper Alloy offers cost efficiency. Both materials are compatible with gold-plated terminals.
