CWN-361-26-0021 Equivalent & Substitute Parts

Part Overview

The CWN-361-26-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 26-position, 2-row connector operates across -55°C to 125°C and features shrouded 4-wall construction with solder termination. The part maintains Active product status with full RoHS3 compliance and ROHS3 certification. Substitute parts are necessary when addressing obsolescence concerns, managing supply chain constraints, or accommodating specific packaging and compliance requirements in production environments.

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-361-26-0021 is determined by strict alignment with the following core parameters: 26-position configuration, 2-row layout, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole mounting, solder termination, and shrouded 4-wall construction. All substitute parts must maintain these electrical and mechanical specifications to ensure direct compatibility in PCB assembly and mating interface applications.

The substitute parts identified—3429-6002, D3429-6002-AR, N3429-6002RB, and N3429-6003RB—satisfy these core requirements. Variations in contact material, contact finish composition, insulation material formulation, fastening mechanism, and operating temperature ceiling do not preclude substitution when the primary functional parameters remain constant. Product status and compliance certifications are secondary considerations that inform selection strategy but do not eliminate substitution viability based on electrical and mechanical compatibility.

Engineering Selection Recommendations

D3429-6002-AR is the primary substitute for CWN-361-26-0021 in applications requiring active product status and full RoHS3 compliance. This part maintains identical core electrical and mechanical specifications while offering higher current rating (1.75A) and active manufacturing status. Packaging is supplied in tray format with 1805 units in stock.

N3429-6002RB and N3429-6003RB are secondary substitutes suitable for applications where RoHS compliance is required but active product status is not critical. Both parts maintain active status and RoHS compliance. N3429-6002RB features contact length post of 0.112" (2.84mm), while N3429-6003RB provides extended contact length post of 0.155" (3.94mm), matching the CWN-361-26-0021 specification. Selection between these variants depends on PCB thickness and assembly requirements.

The 3429-6002 substitute is not recommended for new designs due to obsolete product status and RoHS non-compliance, despite maintaining core electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can D3429-6002-AR directly replace CWN-361-26-0021 in existing assemblies?

A: Yes. Both parts maintain identical 26-position, 2-row configuration with 0.100" (2.54mm) mating pitch, through-hole mounting, solder termination, and shrouded 4-wall construction. Contact shape differs (circular vs. square), but this does not affect mating interface compatibility. Operating temperature range is reduced from 125°C to 105°C maximum; verify application requirements before substitution.

Q: What is the difference between N3429-6002RB and N3429-6003RB?

A: Both parts are electrically and mechanically equivalent with identical 26-position configuration and core specifications. The primary difference is contact length post: N3429-6002RB provides 0.112" (2.84mm) post length, while N3429-6003RB provides 0.155" (3.94mm) post length. Selection depends on PCB thickness and solder joint depth requirements.

Q: Why is 3429-6002 listed as a substitute if it is obsolete?

A: The 3429-6002 meets all core electrical and mechanical substitution criteria: 26-position, 2-row header with 0.100" (2.54mm) pitch, through-hole mounting, and solder termination. Obsolete status and RoHS non-compliance make it unsuitable for new production but do not eliminate functional compatibility. Existing inventory may be available for legacy system support.

Q: Are there packaging differences between substitute parts?

A: Yes. CWN-361-26-0021 is supplied in standard packaging. D3429-6002-AR is packaged in tray format. N3429-6002RB and N3429-6003RB are supplied in bulk packaging. Verify packaging requirements for automated assembly and handling processes.

Q: What compliance certifications apply to each substitute?

A: CWN-361-26-0021 and D3429-6002-AR hold ROHS3 compliance. N3429-6002RB holds RoHS compliance. N3429-6003RB holds ROHS3 compliance. All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. 3429-6002 is RoHS non-compliant and unsuitable for regulated applications.
