CWN-512-16-0000 Equivalent & Substitute Parts

Part Overview

The CWN-512-16-0000 is a rectangular connector header manufactured by CW Industries, designed for through-hole, right-angle mounting applications. This 16-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and solder termination. The part is Active status and widely used in board-to-cable/wire interconnect applications requiring reliable male pin contact interfaces. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate qualified alternatives.

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-512-16-0000 is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pin contacts
Position Count & Row Configuration: 16 positions arranged in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Orientation: Through-hole, right-angle mounting
Shrouding Design: Shrouded 4-wall construction
Termination Method: Solder termination
Electrical Performance: Current rating and operating temperature range
Compliance Standards: RoHS and flammability ratings

The substitute part N3408-5002RB from 3M meets these core substitution criteria, maintaining identical position count, pitch, mounting type, shrouding configuration, and termination method. Both parts are Active status products with UL94 V-0 flammability ratings and RoHS compliance.

Engineering Selection Recommendations

Both the CWN-512-16-0000 and N3408-5002RB are Active status products with equivalent core mechanical and electrical specifications for standard 16-position, 2.54mm pitch header applications. Selection between these parts should be based on the following factors:

CWN-512-16-0000 (Primary Part): Supports extended operating temperature range to 125°C and provides 1A current rating with nickel post finish. Suitable for applications requiring maximum temperature performance.

N3408-5002RB (Substitute Part): Offers higher current rating of 1.75A with tin post finish and operating temperature range to 105°C. Suitable for applications with higher current requirements within the 105°C thermal envelope. Includes mounting flange feature and push-pull fastening type.

Both parts maintain UL94 V-0 flammability compliance and RoHS certification. Mechanical compatibility is confirmed through identical pitch, position count, mounting type, and shrouding configuration. Minor dimensional variations in contact post length (0.155" vs 0.112") and insulation height (0.350" vs 0.340") are within acceptable tolerance for standard board-to-cable interconnect applications.

Frequently Asked Questions (FAQ)

Q: Are the CWN-512-16-0000 and N3408-5002RB mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (16), row configuration (2 rows), mounting type (through-hole right-angle), and shrouding design (4-wall). Mating contact length is identical at 0.240" (6.10mm). Minor differences in post length and insulation height do not affect mechanical compatibility in standard board-to-cable applications.

Q: What are the key electrical differences between these parts?

A: The N3408-5002RB provides higher current rating (1.75A vs 1A) and operates to 105°C maximum, while the CWN-512-16-0000 extends to 125°C. Both maintain identical gold mating contact finish and UL94 V-0 flammability rating. Post finish differs (nickel vs tin), which may affect long-term corrosion resistance in specific environmental conditions.

Q: Can I use the N3408-5002RB in an application designed for the CWN-512-16-0000?

A: Substitution is valid when the application operates within 105°C maximum temperature and does not exceed 1.75A current per contact. The higher current rating of the substitute part does not create compatibility issues. Verify that the 0.028" (0.71mm) difference in post length does not affect PCB hole depth or solder joint geometry in your specific design.

Q: Are both parts RoHS compliant?

A: Yes. The CWN-512-16-0000 is ROHS3 compliant, and the N3408-5002RB is RoHS compliant. Both parts meet REACH requirements and carry EAR99 ECCN classification.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
