Part Overview

The CWN-352-14-0021 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 production status with full inventory availability (787 pcs in stock). Substitute parts are necessary when the original manufacturer discontinues production, when alternative compliance certifications are required, or when design specifications allow for compatible alternatives meeting the same electrical and mechanical interface requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-352-14-0021 is determined by strict compliance with the following critical parameters:

Primary Matching Criteria (Non-Negotiable):

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Style: Board to Cable/Wire
• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 30.0µin (0.76µm)
• Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters (Allowable Variation):

• Contact Shape: Circular or Square (both acceptable for mating interface)
• Contact Length - Mating: 0.228" to 0.240" (5.80mm to 6.10mm)
• Insulation Height: 0.680" to 0.685" (17.27mm to 17.40mm)
• Operating Temperature: Minimum -55°C, Maximum 105°C or higher
• Current Rating: 1A or higher
• Fastening Type: Latch Lock/Eject Hooks or Push-Pull (both functional for board retention)
• Contact Material: Phosphor Bronze or Copper Alloy (both acceptable conductors)
• Insulation Material: Thermoplastic or Glass-Filled variants (both UL94 V-0 rated)

The four substitute parts listed below meet all primary matching criteria and fall within acceptable ranges for secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (CWN-352-14-0021): Maintain use of the original CWN-352-14-0021 when design specifications require the extended operating temperature range of -55°C to 125°C and ROHS3 compliance is mandatory. This part is in active production with adequate inventory.

Recommended Substitutes (Active Status, RoHS Compliant):

71918-014LF (Amphenol ICC/FCI Quickie™ Series): Select this part when maximum inventory availability is required (1472 pcs in stock). The part meets all primary matching criteria with RoHS compliance. Operating temperature range is not specified in available documentation; applications requiring temperatures above 105°C should not use this substitute without manufacturer confirmation.

N3314-6002RB (3M 3000 Series): This part provides RoHS compliance with higher current rating (1.75A vs. 1A), suitable for applications with increased current demands. Operating temperature range is -55°C to 105°C; applications requiring operation above 105°C require the original CWN-352-14-0021. Inventory availability is high (2110 pcs).

N3314-6003RB (3M 3000 Series): This variant offers the same RoHS compliance and elevated current rating (1.75A) as N3314-6002RB, with extended contact post length (0.155" vs. 0.112"). Select this part only when the longer post length is mechanically compatible with the PCB design. Operating temperature maximum is 105°C.

Avoid Selection (Obsolete Status):

3314-6002 (3M 3000 Series): This part is marked as obsolete and does not meet RoHS compliance requirements. Use only in legacy system maintenance where RoHS exemptions apply and no alternative is available.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CWN-352-14-0021 with any of these parts in a new design?

A: Substitution depends on design requirements. The 71918-014LF, N3314-6002RB, and N3314-6003RB are all active products with RoHS compliance suitable for new designs. However, if your application requires operation above 105°C, only the original CWN-352-14-0021 supports the full -55°C to 125°C range. The 3314-6002 is obsolete and unsuitable for new designs.

Q: What is the difference between N3314-6002RB and N3314-6003RB?

A: Both parts are electrically and mechanically equivalent with identical pitch, position count, and mating interface. The primary difference is contact post length: N3314-6002RB has 0.112" (2.84mm) posts, while N3314-6003RB has 0.155" (3.94mm) posts. Select based on PCB thickness and solder joint requirements. Both support 1.75A current rating.

Q: Are there any compliance differences between the substitute parts?

A: Yes. The CWN-352-14-0021 is ROHS3 compliant. The 71918-014LF, N3314-6002RB, and N3314-6003RB are RoHS compliant. The 3314-6002 is RoHS non-compliant and obsolete. For applications requiring ROHS3 specifically, use only the original CWN-352-14-0021.

Q: What is the difference between circular and square contact shapes?

A: The CWN-352-14-0021 uses circular male pins, while the 3M substitutes (3314-6002, N3314-6002RB, N3314-6003RB) and the Amphenol 71918-014LF use square male pins. Both shapes are mechanically and electrically compatible with standard 0.100" (2.54mm) pitch receptacles. Contact shape does not affect substitution eligibility.

Q: Can I use 71918-014LF if my application requires operation above 105°C?

A: The operating temperature range for 71918-014LF is not specified in available technical documentation. Applications requiring confirmed operation above 105°C should use only the CWN-352-14-0021, which is rated to 125°C. Contact the manufacturer for 71918-014LF temperature specifications if this is critical to your design.

Q: Which substitute offers the best current rating?

A: Both N3314-6002RB and N3314-6003RB support 1.75A, compared to 1A for the original CWN-352-14-0021 and 3314-6002. The 71918-014LF current rating is not specified. Select N3314-6002RB or N3314-6003RB for applications requiring higher current capacity.

Q: What packaging formats are available?

A: CWN-352-14-0021 is supplied in bulk packaging. The 3314-6002 and 3M variants (N3314-6002RB, N3314-6003RB) are supplied in bulk. The 71918-014LF is supplied in tube packaging. Verify packaging compatibility with your assembly process requirements.
