Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The CWN-360-50-0021 and HARTING 09185506924 both support the full operating temperature range of -55°C to 125°C. The 3M parts (D3433-6002-AR, N3433-6002RB, N3433-6003RB) and Amphenol ICC 71918-050LF operate within -55°C to 105°C, which is suitable for applications not requiring the extended upper temperature limit.

Contact post length varies across substitutes. The CWN-360-50-0021 and N3433-6003RB both feature 0.155" (3.94mm) post length, while HARTING 09185506924, Amphenol ICC 71918-050LF, and 3M D3433-6002-AR and N3433-6002RB feature shorter post lengths of 0.114" to 0.112". Post length selection depends on PCB thickness and solder joint requirements in the target application.

Contact finish on the post differs between the original part (Nickel) and all substitutes (Tin). This variation does not prevent functional substitution in standard applications. The 3M parts provide higher current ratings of 1.75A compared to the original 1A specification.

Frequently Asked Questions (FAQ)

Q: What are the core criteria for substituting the CWN-360-50-0021?

A: The substitute part must maintain 50 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, shrouded 4-wall configuration, and push-pull fastening. All identified substitutes meet these requirements.

Q: Does contact shape difference (circular vs. square) affect substitution?

A: Contact shape is a secondary parameter. The CWN-360-50-0021 features circular contacts while most substitutes feature square contacts. Both geometries perform the same electrical function in standard applications.

Q: Are the 3M parts suitable for high-temperature applications?

A: The 3M parts (D3433-6002-AR, N3433-6002RB, N3433-6003RB) operate to 105°C maximum, compared to the CWN-360-50-0021 specification of 125°C. Selection depends on application temperature requirements.

Q: What is the significance of contact post length variation?

A: Post length affects solder joint formation and PCB penetration depth. The CWN-360-50-0021 and N3433-6003RB both feature 0.155" (3.94mm) posts. Shorter post lengths in other substitutes may require PCB design adjustment for adequate solder joint formation.

Q: Does the nickel vs. tin post finish affect performance?

A: Post finish is a secondary parameter. The original part uses nickel while substitutes use tin. Both finishes provide adequate corrosion resistance and solderability in standard applications.

Q: Which substitute offers the highest current rating?

A: The 3M parts (D3433-6002-AR, N3433-6002RB, N3433-6003RB) are rated for 1.75A, compared to the original 1A specification. These parts are suitable for higher current applications.

Q: Are all substitutes RoHS compliant?

A: All identified substitutes comply with RoHS requirements. The CWN-360-50-0021 and D3433-6002-AR are ROHS3 compliant. HARTING 09185506924, Amphenol ICC 71918-050LF, N3433-6002RB, and N3433-6003RB are RoHS compliant.

Q: Does packaging format affect electrical performance?

A: Packaging (Bulk, Tube, Tray) is a logistics parameter and does not affect electrical or mechanical performance. Selection depends on assembly process requirements and inventory management.
