Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core electrical and mechanical requirements for direct substitution with the CWN-351-16-0000.

D3408-6002-AR (3M) offers the highest inventory availability (6514 pcs) and provides increased current rating (1.75A versus 1A), making it suitable for applications requiring higher current capacity. This part is ROHS3 compliant and operates within a -55°C to 105°C temperature range. Tray packaging supports high-volume production environments.

N3408-6002RB and N3408-6003RB (3M) are functionally equivalent alternatives with identical electrical specifications (1.75A current rating, -55°C to 105°C operating range). The primary distinction between these two 3M parts is contact post length: N3408-6002RB provides 0.112" (2.84mm) post length, while N3408-6003RB provides 0.155" (3.94mm) post length. Selection between these variants depends on PCB thickness and solder joint requirements. Both are RoHS compliant with bulk packaging.

71918-016LF (Amphenol ICC/FCI Quickie™ series) provides an alternative from a different manufacturer with tube packaging. This part features square contact geometry and GXT™ gold plating on mating surfaces. Operating temperature range is not specified in available documentation. REACH status indicates this part is REACH Affected, which may require additional compliance verification for certain applications.

For applications requiring the full -55°C to 125°C operating temperature range of the original CWN-351-16-0000, the substitute parts operate at a reduced maximum temperature of 105°C. This represents a 20°C reduction in upper operating limit and must be evaluated against specific application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can I use D3408-6002-AR as a direct replacement for CWN-351-16-0000?

A: Yes. Both parts share identical connector type, contact type, position count, row configuration, pitch, mounting method, termination, and shrouding. The D3408-6002-AR provides higher current rating (1.75A) and operates at -55°C to 105°C. The primary consideration is the reduced upper operating temperature limit (105°C versus 125°C).

Q: What is the difference between N3408-6002RB and N3408-6003RB?

A: Both parts are electrically and mechanically identical except for contact post length. N3408-6002RB has 0.112" (2.84mm) post length, while N3408-6003RB has 0.155" (3.94mm) post length. Selection depends on PCB thickness and solder joint depth requirements for your specific application.

Q: Why does 71918-016LF have square contacts while CWN-351-16-0000 has circular contacts?

A: Contact shape variation (circular versus square) is within acceptable engineering tolerance for this connector category. Both geometries provide equivalent electrical performance and mechanical engagement in standard 0.100" (2.54mm) pitch applications. Square contacts are common in alternative connector designs and do not affect substitution compatibility.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts meet RoHS compliance requirements. The CWN-351-16-0000 and D3408-6002-AR are ROHS3 compliant. The 71918-016LF, N3408-6002RB, and N3408-6003RB are RoHS compliant. For applications requiring ROHS3 specifically, D3408-6002-AR is the preferred substitute.

Q: What packaging options are available?

A: CWN-351-16-0000 is supplied in Bulk packaging. Substitute parts offer alternative packaging: 71918-016LF (Tube), D3408-6002-AR (Tray), N3408-6002RB (Bulk), and N3408-6003RB (Bulk). Packaging selection impacts handling, storage, and production line integration requirements.

Q: Does 71918-016LF have any compliance restrictions I should know about?

A: 71918-016LF is REACH Affected, which may require additional compliance documentation for certain regulated applications or geographic markets. Verify REACH compliance requirements for your specific end-use application before selection.

Q: Can I use these substitutes in applications requiring -55°C to 125°C operation?

A: The substitute parts operate at -55°C to 105°C maximum, which is 20°C lower than the CWN-351-16-0000 specification of -55°C to 125°C. If your application requires the full 125°C upper limit, the CWN-351-16-0000 is the only qualified part from this group.
