CWN-350-10-0021 Equivalent & Substitute Parts

Part Overview

The CWN-350-10-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This shrouded 10-position header with 2.54mm pitch serves board-to-cable/wire interconnection in electronic assemblies. The part is currently active in production with 719 units in stock. Substitute parts may be required due to supply constraints, packaging preferences, or specific application requirements where alternative manufacturers' specifications align with design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (10)
• 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)
• Fastening type (Push-Pull)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1 / Unlimited)

All three substitute parts meet these core electrical and mechanical compatibility criteria. Variations in contact finish, contact material, insulation material composition, and packaging format do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS regulations. Selection between CWN-350-10-0021 and its substitutes should be based on the following factors:

71918-010LF (Amphenol ICC): Highest inventory availability at 3665 units. Tube packaging suitable for automated assembly processes. Operating temperature and current rating specifications are not provided; design verification against application requirements is necessary if these parameters are critical.

D3793-6002-AR (3M): ROHS3 compliant with specified current rating of 1.75A and operating temperature range of -55°C to 105°C. Tray packaging appropriate for moderate-volume production. Contact finish thickness on mating surface is 10.0µin, lower than the main part specification.

N3793-6002RB (3M): ROHS3 compliant with specified current rating of 1.75A and operating temperature range of -55°C to 105°C. Bulk packaging for high-volume applications. Contact finish thickness on post is 200.0µin, significantly higher than other options.

Frequently Asked Questions (FAQ)

Q: Can 71918-010LF be used as a direct replacement for CWN-350-10-0021?

A: Yes, within the scope of the specified electrical and mechanical parameters. The 10-position, 2-row, 2.54mm pitch configuration, through-hole mounting, solder termination, and push-pull fastening are identical. Operating temperature and current rating specifications are not provided for the 71918-010LF; application requirements must be evaluated independently.

Q: What are the differences between the 3M substitutes D3793-6002-AR and N3793-6002RB?

A: Both parts share identical core specifications: 10-position header, 2.54mm pitch, through-hole solder termination, and push-pull fastening. Primary differences are packaging format (Tray vs. Bulk) and contact finish thickness on the post (39.4µin vs. 200.0µin). Packaging selection depends on production volume and assembly process requirements.

Q: Are there temperature rating differences between the main part and substitutes?

A: The CWN-350-10-0021 operates from -55°C to 125°C. The 3M substitutes (D3793-6002-AR and N3793-6002RB) operate from -55°C to 105°C, representing a 20°C reduction in maximum operating temperature. Applications requiring operation above 105°C must use the CWN-350-10-0021 or 71918-010LF if its temperature rating is confirmed.

Q: How do contact material differences affect substitution?

A: The main part uses Phosphor Bronze contacts. Substitutes use Phosphor Bronze (71918-010LF), Brass (D3793-6002-AR), or Copper Alloy (N3793-6002RB). All materials are compatible with the specified electrical and mechanical parameters. Contact material selection does not affect functional interchangeability for the defined parameter set.

Q: What packaging options are available?

A: CWN-350-10-0021 packaging is not specified. Substitutes are available in Tube (71918-010LF), Tray (D3793-6002-AR), and Bulk (N3793-6002RB) formats. Packaging selection should align with production volume, automated assembly capabilities, and inventory management requirements.

Q: Are all parts RoHS compliant?

A: Yes. CWN-350-10-0021 and D3793-6002-AR are ROHS3 compliant. 71918-010LF and N3793-6002RB are RoHS compliant. All parts meet regulatory requirements for restricted substance elimination.
