CWN-360-14-0021 Equivalent & Substitute Parts

Part Overview

The CWN-360-14-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This shrouded 14-position header with 2.54mm pitch serves board-to-cable/wire interconnection in electronic assemblies. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified where electrical and mechanical parameters align with the original specification, enabling component sourcing flexibility while maintaining circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-360-14-0021 is determined by strict alignment of the following parameters:

• Connector geometry: 14 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
• Mounting and termination: Through-hole solder termination
• Shrouding configuration: Shrouded 4-wall design with keying slot and mounting flange
• Contact system: Male pin contacts with gold-plated mating surfaces
• Electrical performance: Minimum 1A current rating, UL94 V-0 flammability compliance
• Environmental rating: MSL 1 (Unlimited) moisture sensitivity

The substitute parts listed—3314-6002, N3314-6002RB, N3314-6003RB, and 71918-014LF—satisfy these core parameters. Variations in contact shape (circular vs. square), post finish composition (nickel vs. tin), insulation material formulation, and operating temperature ceiling do not preclude functional equivalence in standard applications where these parameters are not design-critical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: N3314-6002RB or N3314-6003RB (3M)

Both N3314-6002RB and N3314-6003RB maintain Active product status with full RoHS compliance, matching the regulatory posture of the CWN-360-14-0021. These parts deliver higher current capacity (1.75A vs. 1A), providing design margin in power distribution applications. The distinction between N3314-6002RB and N3314-6003RB lies in post contact length (0.112" vs. 0.155"), with N3314-6003RB matching the original post length specification. Both employ tin-plated posts and copper alloy contact material, suitable for standard solder reflow processes.

Secondary Recommendation: 71918-014LF (Amphenol ICC/FCI)

The 71918-014LF Quickie™ series header maintains Active status and RoHS compliance. This part features phosphor bronze contacts matching the CWN-360-14-0021 material composition and incorporates GXT™ gold plating on mating surfaces. Operating temperature range is not specified in available documentation. This option provides compatibility with existing connector ecosystems where Amphenol ICC components are standardized.

Not Recommended: 3314-6002 (3M)

The 3314-6002 carries Obsolete product status and RoHS non-compliance. While electrically and mechanically equivalent, procurement risk and regulatory constraints make this option unsuitable for new designs or production requiring current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can N3314-6002RB and N3314-6003RB be used interchangeably with CWN-360-14-0021?

A: Both parts satisfy the core substitution criteria: 14-position, 2-row, 2.54mm pitch shrouded headers with through-hole solder termination and gold-plated mating contacts. The primary difference is post contact length. N3314-6003RB matches the original 0.155" (3.94mm) post length, while N3314-6002RB provides 0.112" (2.84mm). Selection depends on PCB stack-up and mating connector depth requirements. Both are RoHS compliant and Active products.

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

A: Contact shape does not affect electrical performance or mating compatibility in standard applications. Circular contacts (CWN-360-14-0021) and square contacts (3M and Amphenol ICC alternatives) both achieve equivalent contact resistance and current-carrying capacity. Selection is driven by connector cavity design and manufacturing process compatibility.

Q: Why does 71918-014LF lack specified operating temperature and current rating?

A: The provided data sheet excerpt does not include these parameters. Consult the complete Amphenol ICC 71918-014LF technical documentation for full environmental and electrical specifications before final design selection.

Q: Is the higher current rating of N3314-6002RB and N3314-6003RB (1.75A vs. 1A) a design requirement?

A: The 1.75A rating provides additional thermal margin and is not a design requirement for applications rated at 1A. Both ratings satisfy the original specification. Higher current capacity may be advantageous in power-sensitive applications or where future design headroom is desired.

Q: What packaging considerations apply to substitute selection?

A: CWN-360-14-0021 is supplied in bulk packaging. Substitute parts are available in bulk (3M series), tube (71918-014LF), or bulk (N3314 series) configurations. Packaging selection affects procurement logistics and automated assembly compatibility. Verify packaging availability with component distributors for production volume requirements.

Q: Are post finish differences (nickel vs. tin vs. tin-lead) significant for solder compatibility?

A: All post finishes are compatible with standard lead-free and lead-containing solder processes. Nickel plating (CWN-360-14-0021) provides enhanced corrosion resistance in high-humidity environments. Tin and tin-lead finishes (substitute parts) are standard for through-hole soldering. Selection is application-dependent; no functional incompatibility exists.
