Engineering Selection Recommendations

All four substitute parts are active production components with equivalent functional capability for the CWN-350-16-0021 application. Selection criteria are based on product status, compliance certifications, and inventory availability:

D3408-6002-AR (3M) offers the highest current rating at 1.75A and largest inventory availability at 6514 units. This part maintains ROHS3 compliance matching the primary part and provides extended operating margin. Tray packaging supports high-volume assembly operations.

N3408-6002RB and N3408-6003RB (3M) are both RoHS compliant alternatives with 1.75A current rating. N3408-6002RB provides contact post length of 0.112" (2.84mm), while N3408-6003RB extends to 0.155" (3.94mm) for applications requiring deeper PCB penetration. Both are available in bulk packaging with comparable inventory levels.

71918-016LF (Amphenol ICC/FCI) is the Quickie™ series option with RoHS compliance and 882 units in stock. This part features GXT™ gold mating contact finish and is supplied in tube packaging. Operating temperature range is not specified; applications requiring the full -55°C to 125°C range should reference the primary part or 3M alternatives.

All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I use 71918-016LF as a direct replacement for CWN-350-16-0021?

A: Yes. Both parts share identical mating pitch (0.100"), row spacing (0.100"), position count (16), and shrouded 4-wall configuration. The 71918-016LF contact length mating dimension is 0.228" versus 0.240" on the primary part, a 0.012" difference within typical mechanical tolerance. Both maintain UL94 V-0 flammability and MSL 1 classification. Operating temperature range is not specified for the 71918-016LF; confirm application requirements if extended temperature operation is needed.

Q: What is the difference between the 3M N3408-6002RB and N3408-6003RB?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications except for contact post length. The N3408-6002RB provides 0.112" (2.84mm) post length, while the N3408-6003RB extends to 0.155" (3.94mm). Selection depends on PCB thickness and solder joint depth requirements. Both are RoHS compliant with 1.75A current rating and -55°C to 105°C operating range.

Q: Does packaging type affect electrical performance?

A: No. Bulk, tube, and tray packaging formats do not affect connector electrical or mechanical performance. Packaging selection is driven by assembly process requirements, inventory management, and handling procedures. The CWN-350-16-0021 is supplied in bulk; substitutes are available in bulk (N3408-6002RB, N3408-6003RB), tube (71918-016LF), or tray (D3408-6002-AR) formats.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts meet RoHS compliance requirements. The primary part and D3408-6002-AR are ROHS3 compliant. The 71918-016LF, N3408-6002RB, and N3408-6003RB are RoHS compliant. Both compliance levels are acceptable for equivalent substitution.

Q: What is the current rating difference between the primary part and 3M substitutes?

A: The CWN-350-16-0021 is rated at 1A. The 3M alternatives (D3408-6002-AR, N3408-6002RB, N3408-6003RB) are rated at 1.75A, providing 75% additional current capacity. The 71918-016LF current rating is not specified. For applications operating at or near 1A, the higher-rated 3M parts provide additional design margin.

Q: Can I mix contact materials between the primary part and substitutes?

A: Yes. The primary part uses phosphor bronze contacts; substitutes use phosphor bronze (71918-016LF), brass (D3408-6002-AR), or copper alloy (N3408-6002RB, N3408-6003RB). All materials are acceptable for equivalent substitution within the specified electrical and mechanical parameters. Contact finish (gold mating, nickel or tin post) is the primary determinant of electrical performance, not base material composition.

Q: What is the maximum operating temperature for each part?

A: The CWN-350-16-0021 operates from -55°C to 125°C. The 3M parts (D3408-6002-AR, N3408-6002RB, N3408-6003RB) operate from -55°C to 105°C, providing 20°C lower maximum temperature. The 71918-016LF operating temperature range is not specified. For applications requiring operation above 105°C, the primary CWN-350-16-0021 part is required.
