Engineering Selection Recommendations

3M Series Substitutes (Direct Manufacturer Alternatives):

N3408-6202RB is the primary direct substitute from 3M. It maintains identical mechanical and electrical specifications to the 3408-6202 while offering RoHS compliance and active product status. This part is recommended for designs requiring minimal validation effort and direct form-fit-function replacement.

D3408-6002-AR and N3408-6002RB are alternative 3M options featuring Push-Pull fastening instead of Latch Lock/Eject Hooks. These parts are suitable for applications where fastening mechanism differences are acceptable. D3408-6002-AR offers the highest inventory availability (6514 units) and ROHS3 compliance.

HARTING Series Substitutes (Cross-Manufacturer Alternatives):

HARTING SEK series connectors (09185165902, 09185166902, 09185166904, 09185166914001, 09185167902, 09185167904, 09195166902) provide functional equivalence with extended operating temperature range (-55°C ~ 125°C) and ROHS3 compliance. These parts feature variations in contact length dimensions and fastening hook configurations (Long or Short).

For applications requiring the shortest contact length and fastening hook configuration closest to the original 3408-6202, 09185166914001 is specified with Short Latch Lock/Eject Hooks and contact dimensions of 0.228" mating length and 0.114" post length.

Compliance Considerations:

The original 3408-6202 is RoHS non-compliant. All substitute parts listed are either RoHS Compliant or ROHS3 Compliant, supporting modern procurement and environmental compliance requirements. Selection should account for design documentation and certification requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can N3408-6202RB be used as a direct replacement for 3408-6202?

A: Yes. N3408-6202RB maintains identical pitch (2.54mm), position count (16 in 2 rows), mounting type (Through Hole), termination (Solder), shrouding (Shrouded - 4 Wall), and operating temperature range (-55°C ~ 105°C). The primary difference is RoHS compliance status and active product availability. Mechanical and electrical compatibility is confirmed.

Q: What is the difference between Latch Lock/Eject Hooks and Push-Pull fastening?

A: Both fastening types secure the mated connector pair but use different mechanical engagement methods. Latch Lock/Eject Hooks employ hook-based latching with manual eject capability. Push-Pull fastening uses a push-to-connect and pull-to-disconnect mechanism. Selection depends on application requirements for mating force and disconnect procedure. Contact length dimensions may also differ between fastening types.

Q: Are HARTING SEK series connectors mechanically compatible with 3M 3000 series?

A: HARTING SEK series connectors share the same pitch (2.54mm), position count (16 in 2 rows), mounting type (Through Hole), termination (Solder), and shrouding (Shrouded - 4 Wall). However, contact length dimensions vary. Verify that mating connector cavity depths and PCB layout accommodate the specific contact length of the selected HARTING part before implementation.

Q: What packaging options are available?

A: Substitute parts are available in Tray or Bulk packaging. Tray packaging is specified for parts ending in "04" (e.g., 09185166904, 09185167904). Bulk packaging is specified for parts ending in "02" or "02RB" (e.g., 09185166902, N3408-6202RB). Packaging selection does not affect electrical or mechanical performance.

Q: Why do some HARTING parts have extended operating temperature range (-55°C ~ 125°C)?

A: Extended temperature range is a material and design specification provided by HARTING for their SEK series. This specification exceeds the original 3408-6202 range (-55°C ~ 105°C) and is compatible with applications requiring higher temperature operation. Applications limited to -55°C ~ 105°C may use these parts without thermal derating.

Q: Is RoHS compliance mandatory for substitute selection?

A: RoHS compliance is determined by application requirements and regional regulations. The original 3408-6202 is RoHS non-compliant. All listed substitutes are RoHS Compliant or ROHS3 Compliant. For new designs or applications subject to RoHS directives, compliant substitutes are required. For legacy system maintenance, non-compliant parts may remain acceptable depending on procurement policy.
