CWN-351-10-0021 Equivalent & Substitute Parts

Part Overview

The CWN-351-10-0021 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 680 units in stock. Substitute parts are identified to address inventory availability, lead time constraints, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-351-10-0021 is determined by strict adherence to the following core 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
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 compatibility criteria. Variations in contact finish, fastening type, insulation material composition, and contact geometry do not preclude substitution when these core parameters align.

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS regulations. The CWN-351-10-0021 operates across -55°C to 125°C with a 1A current rating. The 3M alternatives (D3793-6002-AR and N3793-6002RB) operate to 105°C maximum and support 1.75A current, making them suitable for applications within the 105°C thermal envelope. The Amphenol ICC 71918-010LF does not specify operating temperature or current rating in the provided data.

Contact length variations exist across all parts. The CWN-351-10-0021 features 0.090" post length, while substitutes range from 0.112" to 0.114". Insulation height remains consistent within 0.680" to 0.685" across all options. Contact finish differences (nickel post on CWN-351-10-0021 versus tin on substitutes) and fastening type variations (latch lock/eject hooks on CWN-351-10-0021 versus push-pull on substitutes) do not affect core electrical compatibility.

Selection should prioritize application thermal and current requirements. For applications requiring operation above 105°C or sustained 1A+ current, the CWN-351-10-0021 remains the specified choice. For standard applications within 105°C and 1.75A limits, the 3M parts provide equivalent functionality with higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can 71918-010LF replace CWN-351-10-0021 in all applications?

A: The 71918-010LF meets core mechanical and electrical compatibility criteria. However, operating temperature and current rating are not specified for this part. Applications requiring confirmed thermal performance above 105°C or sustained current above 1A should reference the CWN-351-10-0021 specifications.

Q: What is the difference between latch lock/eject hooks and push-pull fastening?

A: The CWN-351-10-0021 uses latch lock/eject hooks for mating security. Substitute parts use push-pull fastening. Both mechanisms provide secure mating; the selection depends on application assembly and disassembly requirements.

Q: Are the 3M parts (D3793-6002-AR and N3793-6002RB) interchangeable?

A: Both 3M parts share identical core specifications and operate within -55°C to 105°C and 1.75A ratings. Primary differences are packaging (tray versus bulk) and contact material (brass versus copper alloy). They are functionally equivalent for standard applications.

Q: Does contact finish affect electrical performance?

A: Contact finish variations (gold thickness, nickel versus tin post finish) do not affect core electrical compatibility. All parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity. Finish selection is application-dependent for corrosion resistance and contact wear characteristics.

Q: What packaging options are available?

A: CWN-351-10-0021 is supplied in bulk. The 71918-010LF is supplied in tube packaging. The D3793-6002-AR is supplied in tray. The N3793-6002RB is supplied in bulk. Packaging selection depends on assembly line requirements and inventory management.

Q: Are all parts RoHS compliant?

A: Yes. The CWN-351-10-0021 and D3793-6002-AR are ROHS3 compliant. The 71918-010LF and N3793-6002RB are RoHS compliant. All parts meet regulatory requirements for lead-free manufacturing.
