Substitute Part Grouping Explanation

Substitution eligibility for the CWN-502-60-0021 is determined by strict equivalence across the following critical parameters:

• Connector positioning and pitch: 60 positions, 2 rows, 0.100" (2.54mm) mating pitch, and 0.100" (2.54mm) row spacing
• Mounting and orientation: Through-hole, right-angle configuration
• Shrouding design: Shrouded with 4-wall construction
• Contact system: Male pin contacts with gold mating finish
• Electrical performance: Minimum 1A current rating capability
• Environmental compliance: UL94 V-0 flammability rating and RoHS compliance
• Temperature operation: Functional range of -55°C to 125°C or equivalent

The substitute part N3372-5002RB from 3M meets these core substitution criteria while maintaining active product status and equivalent mechanical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CWN-502-60-0021 and N3372-5002RB maintain active product status and satisfy UL94 V-0 flammability requirements with RoHS compliance. The N3372-5002RB provides higher current capacity at 1.75A versus 1A, supporting applications with increased electrical demand. The CWN-502-60-0021 operates to 125°C maximum temperature, while the N3372-5002RB is rated to 105°C. Selection between these parts should be based on specific application temperature and current requirements within the stated operating ranges. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification and REACH Unaffected status, indicating equivalent environmental handling and regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can N3372-5002RB replace CWN-502-60-0021 in all applications?

A: Substitution is valid when application current requirements do not exceed 1.75A and operating temperature remains within -55°C to 105°C. If the application requires operation above 105°C, the CWN-502-60-0021 with its 125°C rating is required.

Q: What are the mechanical compatibility considerations?

A: Both parts share identical 60-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing. Through-hole, right-angle mounting and 4-wall shrouding are equivalent. Mating interface compatibility is maintained.

Q: Are there differences in contact materials?

A: The CWN-502-60-0021 uses Phosphor Bronze contacts, while the N3372-5002RB uses Copper Alloy contacts. Both materials support the specified current ratings and operating temperatures with gold mating finish at 30.0µin thickness.

Q: Do both parts meet the same regulatory standards?

A: Both parts are UL94 V-0 rated, RoHS compliant, and REACH Unaffected. MSL classification is identical at Level 1 (Unlimited). Regulatory compliance is equivalent for standard industrial applications.

Q: What is the difference in contact post specifications?

A: The CWN-502-60-0021 has 0.090" (2.29mm) post length with 50.0µin (1.27µm) nickel finish. The N3372-5002RB has 0.112" (2.84mm) post length with 200.0µin (5.08µm) tin finish. These differences do not affect mating compatibility but may influence solder joint characteristics during assembly.
