CWN-351-14-0021 Equivalent & Substitute Parts

Part Overview

The CWN-351-14-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 14-position, 2-row connector with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection in electronic assemblies. The part is currently in active product status with 855 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when design requirements demand alternative compliance certifications, or when specific performance characteristics of alternative manufacturers better suit application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-351-14-0021 is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (14) and rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Shrouding configuration (Shrouded - 4 Wall)
• Style (Board to Cable/Wire)
• Material flammability rating (UL94 V-0)

The identified substitute parts—3314-6002, N3314-6002RB, N3314-6003RB, and 71918-014LF—satisfy these core mechanical and electrical compatibility requirements. Variations in contact finish, insulation material composition, fastening type, and operating temperature ranges represent secondary differences that do not prevent functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

CWN-351-14-0021 (Primary Part): Recommended for new designs requiring ROHS3 compliance and extended operating temperature range to 125°C. Active product status ensures long-term availability and supply chain stability.

N3314-6002RB and N3314-6003RB (Preferred Substitutes): Both parts maintain RoHS compliance and active product status. N3314-6002RB features a contact post length of 0.112" (2.84mm), while N3314-6003RB provides an extended post length of 0.155" (3.94mm). Both support higher current ratings (1.75A) compared to the primary part. Operating temperature range is limited to -55°C ~ 105°C. These parts are suitable for applications where the reduced temperature ceiling does not conflict with system requirements.

71918-014LF (Alternative Substitute): Manufactured by Amphenol ICC (FCI) under the Quickie™ series, this part maintains active product status and RoHS compliance. Contact finish includes GXT™ technology. Operating temperature and current rating specifications are not provided. Supplied in tube packaging rather than bulk. Suitable for applications where manufacturer diversity is a design requirement.

3314-6002 (Not Recommended): This part carries obsolete product status and RoHS non-compliance. Use only when existing inventory must be consumed or when legacy system maintenance requires exact historical part matching.

Frequently Asked Questions (FAQ)

Q: Can N3314-6002RB and N3314-6003RB be used interchangeably with CWN-351-14-0021?

A: Both parts satisfy the core mechanical and electrical compatibility parameters. The primary difference is contact post length: N3314-6002RB provides 0.112" (2.84mm) post length, while N3314-6003RB provides 0.155" (3.94mm). Selection depends on PCB thickness and application-specific mounting requirements. Operating temperature range is reduced to -55°C ~ 105°C compared to the primary part's -55°C ~ 125°C specification.

Q: What is the significance of contact shape differences (circular vs. square)?

A: Contact shape variation does not prevent functional substitution when mating pitch, row spacing, and shrouding configuration remain constant. Both circular and square contact geometries maintain electrical continuity and mechanical engagement within the specified 0.100" (2.54mm) pitch tolerance.

Q: Why is 3314-6002 listed as a substitute if it is obsolete?

A: The 3314-6002 is included for reference in legacy system documentation and for applications where existing inventory must be utilized. New designs should not specify this part due to obsolete status and RoHS non-compliance.

Q: Does packaging format (bulk vs. tube) affect electrical or mechanical compatibility?

A: Packaging format does not affect connector performance. The choice between bulk and tube packaging is a procurement and logistics consideration. 71918-014LF is supplied in tube packaging, while other substitutes are available in bulk format.

Q: What is the impact of higher current ratings in N3314-6002RB and N3314-6003RB?

A: The 1.75A current rating in these parts exceeds the primary part's 1A specification. This represents a performance enhancement and does not create compatibility issues. Applications designed for 1A operation remain fully compatible with these higher-rated substitutes.

Q: Are there compliance differences between substitute parts?

A: Yes. CWN-351-14-0021 is ROHS3 compliant. N3314-6002RB, N3314-6003RB, and 71918-014LF are RoHS compliant. The 3314-6002 is RoHS non-compliant. Applications subject to ROHS3 requirements must use CWN-351-14-0021 or equivalent ROHS3-certified alternatives.
