Substitute Part Grouping Explanation

Substitution eligibility for the CWN-562-16-0021 is determined by the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 16
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Shrouding: Shrouded - 4 Wall
Mounting Type: Through Hole
Termination: Solder
Material Flammability Rating: UL94 V-0
Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts match these core parameters. Variations in contact material, contact finish specifications, fastening type, and insulation material do not prevent functional substitution when the above criteria are met. Operating temperature ranges and current ratings may vary; selection should account for specific application requirements.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and comply with RoHS requirements. The CWN-562-16-0021 operates across -55°C to 125°C with 1A current rating. Substitute parts from 3M (N3408-6303RB, D3408-6002-AR, N3408-6002RB, N3408-6003RB) operate within -55°C to 105°C and support 1.75A current rating, providing higher current capacity within a narrower temperature range. The Amphenol ICC part (71918-016LF) does not specify operating temperature or current rating in the provided data.

Selection between substitutes should prioritize application requirements for operating temperature and current load. For applications requiring the full -55°C to 125°C range, the CWN-562-16-0021 remains the specified choice. For applications within -55°C to 105°C with current demands up to 1.75A, 3M substitutes provide equivalent functionality with higher current capacity. All parts maintain UL94 V-0 flammability rating and MSL 1 classification.

Frequently Asked Questions (FAQ)

Q: Can N3408-6303RB replace CWN-562-16-0021 in all applications?

A: N3408-6303RB is functionally equivalent for applications operating within -55°C to 105°C. If your application requires operation above 105°C up to 125°C, the CWN-562-16-0021 is required. Both parts support the same 16-position 2.54mm pitch configuration and solder termination.

Q: What is the difference between push-pull and latch lock fastening types?

A: Fastening type affects mating and unmating force characteristics. CWN-562-16-0021 uses latch lock/eject hooks with long engagement. D3408-6002-AR, N3408-6002RB, N3408-6003RB, and 71918-016LF use push-pull fastening. Both types are mechanically compatible with 16-position 2.54mm pitch headers; selection depends on application requirements for connection security and ease of disconnection.

Q: Are there packaging differences between substitute parts?

A: Yes. CWN-562-16-0021 is supplied in standard packaging. N3408-6303RB, N3408-6002RB, and N3408-6003RB are supplied in Bulk packaging. D3408-6002-AR is supplied in Tray. 71918-016LF is supplied in Tube. Packaging does not affect electrical or mechanical compatibility; it affects handling, storage, and procurement logistics.

Q: What contact material differences exist among substitutes?

A: CWN-562-16-0021 uses phosphor bronze contacts. 3M parts (N3408-6303RB, D3408-6002-AR, N3408-6002RB, N3408-6003RB) use copper alloy or brass contacts. 71918-016LF uses phosphor bronze. Contact material variations do not prevent functional substitution when all other parameters match.

Q: Do all parts have keying slots?

A: Yes. All listed parts include keying slot features for polarization control, ensuring correct mating orientation.
