CWN-352-10-0021 Equivalent & Substitute Parts

Part Overview

The CWN-352-10-0021 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 requirements. The part is currently active in production with 981 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where form factor and performance requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-352-10-0021 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)
• Shrouding: Shrouded - 4 Wall
• Mounting type: Through Hole
• Termination: Solder
• Style: Board to Cable/Wire or Board to Board or Cable
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

All three substitute parts (71918-010LF, D3793-6002-AR, N3793-6002RB) meet these core electrical and mechanical requirements. Variations in contact finish thickness, fastening type, insulation material composition, and contact shape do not prevent functional substitution when these primary parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS requirements. The CWN-352-10-0021 operates across -55°C to 125°C with a 1A current rating. The 3M alternatives (D3793-6002-AR and N3793-6002RB) support higher current ratings of 1.75A but operate within a narrower temperature range of -55°C to 105°C. The Amphenol ICC 71918-010LF does not specify operating temperature or current rating in the provided data.

For applications requiring the full -55°C to 125°C operating range, the CWN-352-10-0021 remains the primary choice. For applications operating within -55°C to 105°C where higher current capacity is beneficial, D3793-6002-AR or N3793-6002RB provide equivalent mechanical and electrical substitution. Contact finish variations (nickel post on CWN-352-10-0021 versus tin post on substitutes) and contact shape differences (circular versus square) do not affect functional interchangeability when mating interface geometry and pitch specifications remain identical.

Frequently Asked Questions (FAQ)

Q: Can 71918-010LF replace CWN-352-10-0021 in all applications?

A: The 71918-010LF meets all core mechanical and electrical substitution criteria: 10-position, 2-row, 2.54mm pitch, shrouded 4-wall header with through-hole solder termination. Operating temperature and current rating are not specified for this part. Substitution is valid for applications where these parameters are not critical constraints.

Q: What is the difference between D3793-6002-AR and N3793-6002RB?

A: Both parts are 3M rectangular connectors with identical mechanical specifications and operating temperature range (-55°C to 105°C). The primary differences are packaging (D3793-6002-AR ships in trays; N3793-6002RB ships in bulk) and contact finish thickness on the post (D3793-6002-AR: 39.4µin; N3793-6002RB: 200.0µin). Electrical and mechanical performance are equivalent.

Q: Does the contact shape difference (circular versus square) affect compatibility?

A: Contact shape variation does not prevent functional substitution. The CWN-352-10-0021 features circular contacts; substitute parts feature square contacts. Both geometries maintain the same mating pitch and row spacing, ensuring mechanical and electrical compatibility with standard 2.54mm pitch receptacles.

Q: Why does CWN-352-10-0021 specify a higher operating temperature than the 3M alternatives?

A: Operating temperature range is determined by insulation material composition and design specifications. The CWN-352-10-0021 supports -55°C to 125°C; the 3M D3000 and 3000 series support -55°C to 105°C. Selection between these parts depends on application temperature requirements.

Q: Are all substitute parts RoHS compliant?

A: All parts listed meet RoHS requirements. CWN-352-10-0021 and D3793-6002-AR are ROHS3 compliant. 71918-010LF and N3793-6002RB are RoHS compliant. Both compliance levels are acceptable for applications requiring lead-free construction.

Q: What packaging options are available?

A: CWN-352-10-0021 packaging is not specified in the provided data. 71918-010LF is supplied in tubes; D3793-6002-AR is supplied in trays; N3793-6002RB is supplied in bulk. Packaging selection depends on assembly process requirements and volume needs.
