Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet the core mechanical and electrical requirements of the HARTING 09185105321. Selection among substitutes should be based on the following factors:

RoHS3 Compliance Priority: Parts with ROHS3 Compliant status (Molex 0702471051, TE Connectivity 2-1761605-3, 3M D2510-5002-AR, Samtec HTST series) align with the original specification and are preferred for applications requiring strict RoHS3 adherence.

Operating Temperature Range: The HARTING original and Samtec HTST series (HTST-105-04-G-D-RA, HTST-105-04-L-D-RA, HTST-105-04-S-D-RA) support the full -55°C to 125°C range. TE Connectivity 2-1761605-3 operates to -65°C but is limited to 105°C. 3M 30310-5002HB and D2510-5002-AR support -55°C to 105°C. Parts without specified operating temperature (Molex, Amphenol ICC Quickie series) require application-specific validation.

Packaging Considerations: The original HARTING part is supplied in Bulk packaging. Molex 0702471051 and 3M D2510-5002-AR are also Bulk packaged. Amphenol ICC Quickie series (10056845-110LF, 75867-101LF, 75867-301LF) and Samtec HTST series are supplied in Tube packaging, which may affect procurement and handling workflows.

Contact Material and Finish: Phosphor Bronze contacts (Molex, TE Connectivity, Amphenol ICC, Samtec) and Brass contacts (3M) provide equivalent performance to the original Copper Alloy specification. Gold plating thickness varies; the original specifies 30.0µin (0.76µm) on mating surfaces.

Fastening Type Variation: The original uses Latch Holder fastening. Substitutes employ Push-Pull or Detent Lock mechanisms, which are functionally equivalent for board-to-cable/wire applications but may require connector-specific mating hardware.

Frequently Asked Questions (FAQ)

Q: Can I substitute the HARTING 09185105321 with any of the listed parts without PCB redesign?

A: Yes. All substitute parts share identical pitch (0.100" / 2.54mm), position count (10 in 2 rows), mounting type (through-hole right-angle), and shrouding (4-wall). PCB footprints are compatible. However, verify that mating connectors are compatible with the substitute's fastening type (Push-Pull, Detent Lock, or Latch Holder).

Q: What is the difference between the Amphenol ICC Quickie series parts (75867-101LF, 75867-301LF, 10056845-110LF)?

A: All three are Amphenol ICC Quickie series headers with identical mechanical specifications. The primary difference is contact finish thickness on the mating surface: 75867-101LF and 75867-301LF specify 30.0µin (0.76µm) and 15.0µin (0.38µm) respectively, while 10056845-110LF specifies 30.0µin (0.76µm). Contact finish thickness on the post also varies. Selection depends on application-specific wear and corrosion requirements.

Q: Are the Samtec HTST series parts (HTST-105-04-G-D-D-RA, HTST-105-04-L-D-RA, HTST-105-04-S-D-RA) interchangeable?

A: These three Samtec parts are mechanically and electrically interchangeable. Differences are in post contact finish: HTST-105-04-G-D-RA uses Gold, HTST-105-04-L-D-RA uses Tin, and HTST-105-04-S-D-RA uses Tin. All support the full -55°C to 125°C operating range and 3.4A per contact current rating, exceeding the original specification.

Q: Which substitute offers the best compliance for automotive or medical applications?

A: TE Connectivity 2-1761605-3 explicitly lists Automotive and Medical applications. Samtec HTST series parts support extended temperature range (-55°C to 125°C) and higher current rating (3.4A per contact), suitable for demanding environments. Verify application-specific certifications and qualification requirements with the connector manufacturer.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not preclude substitution if the application operates within the substitute part's specified range. The original HARTING part supports -55°C to 125°C. Samtec HTST series matches this range. TE Connectivity 2-1761605-3 extends to -65°C but limits to 105°C. 3M parts support -55°C to 105°C. Confirm application temperature requirements before selection.

Q: What is the impact of different insulation materials (PBT, Thermoplastic, LCP)?

A: All insulation materials specified meet UL94 V-0 flammability requirements. PBT (original and Molex) provides standard performance. Thermoplastic (Amphenol ICC) and LCP (Samtec) offer alternative material properties. LCP provides superior dimensional stability and lower moisture absorption, beneficial for high-reliability applications. Material selection should align with application environmental and thermal requirements.

Q: Can I mix and match mating connectors from different manufacturers?

A: Mating compatibility depends on pitch, position count, and contact geometry alignment. All listed parts share 0.100" (2.54mm) pitch and 10-position 2-row configuration. However, fastening mechanisms differ (Latch Holder, Push-Pull, Detent Lock). Verify that mating connectors are designed for the specific fastening type of the selected header. Cross-manufacturer mating is not guaranteed without explicit compatibility documentation.

Q: What packaging format should I select?

A: The original HARTING part is supplied in Bulk. Molex 0702471051 and 3M D2510-5002-AR are Bulk packaged. Amphenol ICC Quickie series and Samtec HTST series are Tube packaged. Bulk packaging is suitable for high-volume assembly. Tube packaging may be preferred for lower-volume or manual assembly workflows. Confirm packaging compatibility with your procurement and assembly processes.
