Engineering Selection Recommendations

All substitute parts maintain active product status and comply with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. Selection among substitutes should be based on the following factors:

CWN-352-50-0021 (CW Industries): Primary specification with 1A current rating, nickel post finish, and phosphor bronze contacts. Supports operating temperature to 125°C. ROHS3 compliant.

09185506924 (HARTING): Equivalent mechanical and electrical characteristics with push-pull fastening. ROHS3 compliant. Packaging available in bulk.

71918-050LF (Amphenol ICC): Quickie™ series with GXT™ gold mating finish and push-pull fastening. RoHS compliant. Tube packaging. Slightly reduced mating contact length (0.228" vs. 0.240").

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the CWN-352-50-0021?

A: Yes, all listed substitute parts share the same core electrical and mechanical specifications: 50-position, 2-row header with 0.100" (2.54mm) pitch, through-hole solder termination, and 4-wall shrouding. Functional compatibility is established for standard board-level applications.

Q: What are the differences in contact post length among the substitutes?

A: The CWN-352-50-0021 has a 0.090" (2.29mm) post length. HARTING 09185506924, Amphenol 71918-050LF, and 3M D3433-6002-AR and N3433-6002RB range from 0.112" to 0.114". The 3M N3433-6003RB offers an extended 0.155" post length for applications requiring deeper solder penetration or specific PCB thickness accommodations.

Q: Are there temperature rating differences?

A: The CWN-352-50-0021 and HARTING 09185506924 support -55°C to 125°C operation. The three 3M variants (D3433-6002-AR, N3433-6002RB, N3433-6003RB) are rated to -55°C to 105°C. Applications requiring the full 125°C upper limit should use the CW Industries or HARTING parts.

Q: What packaging options are available?

A: CWN-352-50-0021 is supplied in standard packaging. HARTING 09185506924 is available in bulk. Amphenol 71918-050LF is supplied in tubes. 3M D3433-6002-AR is supplied in trays. 3M N3433-6002RB and N3433-6003RB are available in bulk. Packaging selection depends on assembly process requirements and inventory management.

Q: What is the difference between contact finishes?

A: The CWN-352-50-0021 uses nickel post finish with gold mating contacts. All substitutes use tin post finish with gold mating contacts. The Amphenol 71918-050LF specifies GXT™ gold mating finish. These finish variations do not affect functional compatibility in standard applications.

Q: Which substitute offers the highest current rating?

A: The 3M variants (D3433-6002-AR, N3433-6002RB, N3433-6003RB) are rated for 1.75A, compared to the CWN-352-50-0021 at 1A. The HARTING and Amphenol parts do not specify current ratings in the provided data.

Q: Are all parts RoHS compliant?

A: Yes. The CWN-352-50-0021, HARTING 09185506924, and 3M D3433-6002-AR are ROHS3 compliant. The Amphenol 71918-050LF and 3M N3433-6002RB and N3433-6003RB are RoHS compliant. All meet regulatory requirements for lead-free applications.
