Engineering Selection Recommendations

All identified substitute parts maintain active production status and meet UL94 V-0 flammability requirements. Selection among substitutes depends on specific application constraints:

TE Connectivity AMP-Latch Series (499160-9, 499910-9, 5499160-9, 5499910-9): These parts provide direct functional equivalence with shorter contact post lengths (0.110" / 2.79mm) compared to the HARTING original. Parts 5499160-9 and 5499910-9 carry ROHS3 compliance status. The 499160-9 and 499910-9 variants show "Not applicable" RoHS status, indicating older product lines. These are suitable for applications where reduced post length is acceptable and where ROHS3 compliance is required (5499160-9, 5499910-9).

TE Connectivity AMP-Latch Series with Extended Post (5499374-9, 5499911-9): These variants feature longer contact posts (0.155" / 3.94mm) and extended operating temperature range (-65°C to 105°C). Both carry RoHS compliance. These are appropriate for applications requiring deeper PCB penetration or extended low-temperature operation.

Amphenol ICC Quickie™ Series (71918-240LF): This part offers RoHS compliance with slightly reduced mating contact length (0.228" / 5.80mm) and comparable post length (0.114" / 2.90mm). Insulation height matches the HARTING original more closely (0.685" vs. 0.681"). Suitable for applications where Amphenol supply chain preference exists.

3M 3000 Series (N3432-6202RB, N3432-6203RB): Both variants provide RoHS compliance with insulation height closely matching the HARTING original (0.680" / 17.27mm). N3432-6202RB features standard post length (0.112" / 2.84mm), while N3432-6203RB provides extended post length (0.155" / 3.94mm). Both support 1.75A current rating. Suitable for applications requiring 3M component qualification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the HARTING 09185405902 with any of the listed parts?

A: Yes, all listed parts are functionally equivalent for applications requiring 40-position, 2-row, 2.54mm pitch rectangular connectors with through-hole solder termination and 4-wall shrouding. However, verify that your PCB design accommodates variations in contact post length and insulation height, as these differ among substitutes.

Q: What is the primary difference between TE Connectivity parts with different base numbers (499160-9 vs. 5499160-9)?

A: The primary difference is RoHS compliance status. Parts 5499160-9 and 5499910-9 carry ROHS3 compliance, while 499160-9 and 499910-9 show "Not applicable" status. Additionally, contact finish thickness on the mating surface varies: 499160-9 and 5499160-9 specify 30.0µin (0.76µm), while 499910-9 and 5499910-9 specify 15.0µin (0.38µm).

Q: How do contact post length variations affect compatibility?

A: Contact post length determines how deeply the connector penetrates the PCB. The HARTING original specifies 0.177" (4.50mm), while most TE Connectivity substitutes provide 0.110" (2.79mm). Extended-post variants (5499374-9, 5499911-9, N3432-6203RB) offer 0.155" (3.94mm). Verify your PCB thickness and via depth accommodate the selected post length to ensure proper solder joint formation and mechanical stability.

Q: What packaging options are available?

A: The HARTING 09185405902 is supplied in Bulk packaging. TE Connectivity offers Bulk packaging for most variants (499160-9, 499910-9, 5499160-9, 5499910-9) and Tray packaging for extended-post versions (5499374-9, 5499911-9). Amphenol ICC 71918-240LF is supplied in Tube packaging. 3M parts are supplied in Bulk packaging. Select based on your procurement and handling requirements.

Q: Are there temperature range limitations I should consider?

A: The HARTING original operates from -55°C to 125°C. Most TE Connectivity and 3M substitutes operate from -55°C to 105°C, providing a 20°C reduction in maximum temperature. Extended-range variants (5499374-9, 5499911-9) extend the minimum temperature to -65°C but maintain 105°C maximum. If your application requires operation above 105°C, the HARTING original is the only option among these substitutes.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. The HARTING original specifies 30.0µin (0.76µm) on the mating surface. TE Connectivity parts vary between 15.0µin (0.38µm) and 30.0µin (0.76µm). Thicker finishes provide longer service life in high-cycle mating applications. For static or low-cycle applications, both thicknesses are acceptable.

Q: Can I mix different substitute parts in the same assembly?

A: While all parts are mechanically and electrically compatible, mixing different manufacturers or variants within a single assembly may complicate procurement, inventory management, and future maintenance. Standardize on a single part number per assembly when possible.
