Engineering Selection Recommendations

Direct Electrical Equivalents (Identical Flange Configuration):

The part 09663516513 (HARTING) and D25S24A6GV00LF (Amphenol ICC FCI) provide the closest functional equivalence to L17HTNBHSOL2RM84C. Both maintain the mating side female screwlock (4-40) flange configuration. The 09663516513 offers higher current rating (6.5A versus 5A) and ROHS3 compliance. The D25S24A6GV00LF maintains identical current rating (5A) and contact finish thickness (30.0µin) with RoHS compliance and extended temperature operation to 125°C.

Solder Termination Alternatives (Alternative Flange Configurations):

Parts 2-338315-2, 6-338315-2, D25S24A4GL00LF, D25S24A4GX00LF, D25S24A4PL00LF, D25S24A4PX00LF, and D25S24A6GX00LF maintain solder termination compatibility but feature housing/shell mounting configurations (M3 or 4-40 threaded). These parts are suitable for applications where mechanical mounting interface can accommodate alternative flange designs. All maintain UL94 V-0 flammability rating and MSL 1 classification.

Non-Equivalent Termination:

Part 5745922-2 (TE Connectivity AMP) features press-fit termination rather than solder termination. This part is not suitable for direct substitution in applications requiring solder attachment to printed circuit boards.

Compliance Considerations:

All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. RoHS compliance is confirmed for all listed alternatives. REACH status varies; parts designated as REACH Unaffected or REACH Compliant are suitable for applications with REACH requirements.

Temperature Operating Range:

The main part L17HTNBHSOL2RM84C operates to 150°C. Substitute parts operate to 105°C or 125°C maximum. Applications requiring operation above 125°C must retain the original part specification.

Frequently Asked Questions (FAQ)

Q: Can D25S24A6GV00LF directly replace L17HTNBHSOL2RM84C in existing designs?

A: Yes. Both parts feature 25 position D-Sub receptacle configuration, mating side female screwlock (4-40) flange, solder termination, 5A current rating, UL94 V-0 flammability rating, and MSL 1 classification. The D25S24A6GV00LF operates to 125°C maximum versus 150°C for the original part. Verify application temperature requirements before substitution.

Q: What is the difference between mating side female screwlock and housing/shell mounting flanges?

A: Mating side female screwlock (4-40) flanges attach directly to the mating connector shell using 4-40 screws. Housing/shell mounting flanges (M3 or 4-40) attach to the printed circuit board or enclosure structure. These configurations are mechanically incompatible; selection depends on the application's mechanical interface design.

Q: Why is 5745922-2 listed if it uses press-fit termination instead of solder?

A: Part 5745922-2 is included in the substitute list because it matches all other critical parameters (25 positions, DB/B shell size, through-hole mounting, UL94 V-0, MSL 1). However, press-fit termination is fundamentally different from solder termination. This part is suitable only for applications designed for press-fit attachment and is not a direct replacement for solder-based designs.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS compliant or ROHS3 compliant. The original part L17HTNBHSOL2RM84C is RoHS Compliant. Verify specific RoHS revision requirements for your application.

Q: What is the significance of contact finish thickness (30.0µin versus Flash)?

A: Contact finish thickness affects durability and wear resistance. The original part specifies 30.0µin (0.76µm) gold plating. Substitute parts with flash gold plating provide thinner coverage. For applications with high mating cycle requirements or critical signal integrity, the thicker 30.0µin finish is preferred. Parts D25S24A6GV00LF and D25S24A6GX00LF maintain this specification.

Q: Can I substitute a part with higher current rating (6A or 6.5A) for the 5A rated original?

A: Yes. Higher current ratings indicate the part can safely handle greater current loads. Substituting a 6A or 6.5A rated part for a 5A rated part does not degrade performance in applications operating at or below 5A. The application's actual current requirements determine the minimum acceptable rating.

Q: What packaging differences exist between substitute parts?

A: The original part L17HTNBHSOL2RM84C is supplied in Tray packaging. Substitute parts are supplied in either Tray or Bulk packaging. Packaging affects handling, storage, and ordering quantities but does not affect electrical or mechanical performance. Verify packaging requirements for your procurement and assembly processes.

Q: Are there voltage rating differences between the original and substitute parts?

A: The original part specifies 600V rating. Most substitute parts do not specify voltage rating in the provided data. Parts D25S24A series specify 300V rating. For applications requiring 600V isolation or withstand voltage, verify that substitute parts meet the specific voltage requirement before selection.

Q: Which substitute part offers the best overall compatibility?

A: Part D25S24A6GV00LF (Amphenol ICC FCI) provides the highest compatibility: identical 5A current rating, matching 30.0µin gold contact finish thickness, mating side female screwlock (4-40) flange configuration, solder termination, UL94 V-0 rating, and MSL 1 classification. Operating temperature extends to 125°C (versus 150°C for original). This part is suitable for direct substitution in applications not exceeding 125°C operation.
