Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-512-16-0021 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 16 positions in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding Design: Shrouded with 4-wall construction
• Termination Method: Solder termination
• Mating Contact Finish: Gold plating
• 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 while maintaining functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CWN-512-16-0021 and N3408-5002RB are active production parts with equivalent mechanical and electrical compatibility for standard 16-position, 2.54mm pitch header applications. Selection between these parts should be based on:

CWN-512-16-0021 (CW Industries): Suitable for applications requiring the full operating temperature range of -55°C to 125°C. ROHS3 compliant status applies.

N3408-5002RB (3M): Suitable for applications within the -55°C to 105°C operating range. Provides higher current rating of 1.75A compared to 1A. RoHS compliant status applies. Glass-filled polyester insulation material offers enhanced mechanical properties.

Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating suitability for standard storage and handling conditions without special precautions.

Frequently Asked Questions (FAQ)

Q: Can N3408-5002RB replace CWN-512-16-0021 in all applications?

A: Substitution is valid for applications operating within the -55°C to 105°C temperature range. Applications requiring operation above 105°C must use the CWN-512-16-0021 due to its extended upper temperature limit of 125°C.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), contact mating length (0.240"/6.10mm), and 4-wall shrouded housing design. Mechanical interchangeability is confirmed for standard PCB mounting applications.

Q: Are there differences in contact post specifications?

A: Yes. The CWN-512-16-0021 has a contact post length of 0.155" (3.94mm) with 50.0µin nickel finish, while the N3408-5002RB has a contact post length of 0.112" (2.84mm) with 200.0µin tin finish. These differences may affect solder joint characteristics and should be evaluated for specific PCB thickness requirements.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. The CWN-512-16-0021 is ROHS3 compliant, and the N3408-5002RB is RoHS compliant. Both meet current RoHS directive requirements.

Q: What is the difference in current rating between these parts?

A: The CWN-512-16-0021 is rated for 1A per contact, while the N3408-5002RB is rated for 1.75A per contact. Applications requiring higher current capacity may benefit from the N3408-5002RB.

Q: Are there packaging differences?

A: The CWN-512-16-0021 packaging is not specified in available data. The N3408-5002RB is supplied in bulk packaging.
