Engineering Selection Recommendations

Primary Substitute (Active Status, Full Compliance): D3429-6002-AR is the preferred substitute. It maintains active product status, ROHS3 compliance, and all critical connector parameters. The higher current rating (1.75A vs. 1A) provides additional margin. Packaging is supplied in tray format. Contact post length differs at 0.112" (2.84mm) versus the original 0.155" (3.94mm), requiring PCB layout verification for through-hole depth compatibility.

Secondary Substitutes (Active Status): N3429-6002RB and N3429-6003RB are active alternatives with RoHS compliance. Both provide 1.75A current rating. N3429-6003RB matches the original contact post length (0.155" / 3.94mm), eliminating PCB layout concerns. N3429-6002RB has reduced post length (0.112" / 2.84mm), identical to D3429-6002-AR.

Not Recommended: 3429-6002 carries obsolete product status and RoHS non-compliance, making it unsuitable for new designs or applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can I use N3429-6003RB as a direct replacement for CWN-360-26-0021? A: N3429-6003RB is functionally compatible. Both parts share identical 26-position, 2-row configuration with 2.54mm pitch, through-hole solder termination, and 4-wall shrouding. The contact post length matches at 0.155" (3.94mm). N3429-6003RB provides higher current rating (1.75A) and maintains ROHS3 compliance and active product status.

Q: What is the difference between D3429-6002-AR and N3429-6002RB? A: Both are active 3M alternatives with identical connector geometry and 1.75A current rating. D3429-6002-AR is packaged in trays; N3429-6002RB is bulk packaged. Both have reduced contact post length (0.112" / 2.84mm) compared to the original. D3429-6002-AR uses brass contacts; N3429-6002RB uses copper alloy contacts.

Q: Why does 3429-6002 appear in the substitute list if it is obsolete? A: 3429-6002 is listed as a historical equivalent based on connector parameters but is not recommended for new applications due to obsolete status and RoHS non-compliance.

Q: Does contact post length affect PCB compatibility? A: Contact post length determines the effective solder depth into PCB through-holes. CWN-360-26-0021 and N3429-6003RB both specify 0.155" (3.94mm) post length. D3429-6002-AR and N3429-6002RB specify 0.112" (2.84mm). PCB hole depth and solder fillet requirements must be verified when switching between these lengths.

Q: Are all substitutes RoHS compliant? A: No. 3429-6002 is RoHS non-compliant. D3429-6002-AR, N3429-6002RB, and N3429-6003RB are all RoHS compliant (ROHS3 or RoHS Compliant status).

Q: What is the operating temperature difference? A: CWN-360-26-0021 operates from -55°C to 125°C. All 3M substitutes operate from -55°C to 105°C. Applications requiring operation above 105°C require the original CWN-360-26-0021.
