CWN-360-60-0021 Equivalent & Substitute Parts

Part Overview

The CWN-360-60-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 60-position, 2-row connector operates at 0.100" (2.54mm) pitch and is rated for 1A continuous current across the operating temperature range of -55°C to 125°C. The connector features shrouded 4-wall construction with push-pull fastening and gold-plated mating contacts on phosphor bronze material. As an active product with ROHS3 compliance and UL94 V-0 flammability rating, substitute parts may be required for inventory optimization, regional availability, or specific application requirements where equivalent electrical and mechanical parameters are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWN-360-60-0021 is permissible when the alternative part maintains the following critical parameters: 60-position configuration, 2-row layout, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole mounting, shrouded 4-wall construction, push-pull fastening, solder termination, and male pin contact type. The substitute part N3372-6002RB from 3M satisfies these core mechanical and electrical compatibility requirements. Variations in contact material (phosphor bronze versus copper alloy), contact finish post composition (nickel versus tin), insulation material formulation, contact shape (circular versus square), and operating temperature upper limit (125°C versus 105°C) do not preclude functional substitution when the application thermal envelope and current requirements remain within the substitute part's rated specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CWN-360-60-0021 and N3372-6002RB are active products with UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The CWN-360-60-0021 supports operation to 125°C with 1A current capacity, while the N3372-6002RB operates to 105°C with 1.75A capacity. Selection between these parts depends on application thermal requirements: applications requiring sustained operation above 105°C must use the CWN-360-60-0021. Applications operating within -55°C to 105°C with current demands up to 1.75A may use either part. Both parts maintain ROHS compliance and identical mating contact specifications (gold plating at 30.0µin thickness), ensuring electrical performance equivalence for standard through-hole header applications.

Frequently Asked Questions (FAQ)

Q: Can N3372-6002RB replace CWN-360-60-0021 in all applications?

A: Substitution is valid when the application operates within -55°C to 105°C and does not exceed 1.75A per contact. Applications requiring sustained operation above 105°C must use the CWN-360-60-0021.

Q: What are the mechanical compatibility considerations?

A: Both connectors maintain identical 60-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing. Insulation heights are equivalent (0.681" versus 0.680"), ensuring PCB footprint compatibility. Through-hole mounting, shrouded 4-wall construction, and push-pull fastening are identical.

Q: Do the different contact materials affect electrical performance?

A: Both parts feature gold-plated mating contacts at identical thickness (30.0µin / 0.76µm), ensuring equivalent contact resistance and signal integrity. Differences in base contact material (phosphor bronze versus copper alloy) and post finish (nickel versus tin) do not affect mating surface performance.

Q: Are there compliance differences between these parts?

A: Both parts are UL94 V-0 rated and MSL 1. The CWN-360-60-0021 carries ROHS3 compliance, while the N3372-6002RB carries RoHS compliance. Both are REACH Unaffected and classified as EAR99.

Q: What is the current rating difference impact?

A: The N3372-6002RB supports 1.75A versus 1A for the CWN-360-60-0021. Applications requiring only 1A operation may use either part. Applications approaching or exceeding 1A should verify thermal dissipation characteristics with the selected part.
