CWN-562-40-0000 Equivalent & Substitute Parts

Part Overview

The CWN-562-40-0000 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 40-position, 2-row connector with 0.100" (2.54mm) pitch is actively produced and widely used in board-to-cable/wire interconnect applications. The connector features shrouded 4-wall construction with solder termination and latch lock/eject hooks for secure mating. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate varying procurement requirements across manufacturing environments.

Engineering Selection Recommendations

All three substitute parts are actively produced and meet the core mechanical and electrical requirements for direct substitution with the CWN-562-40-0000. Selection among these alternatives should be based on the following factors:

09185406924 (HARTING SEK Series): This part maintains identical mating contact length and insulation height to the main part. It features a push-pull fastening mechanism and mounting flange. ROHS3 compliance and UL94 V-0 rating are confirmed. Current rating is not specified in available data.

71918-040LF (Amphenol ICC Quickie™ Series): Supplied in tube packaging rather than bulk. Features push-pull fastening and mounting flange. Contact length specifications differ slightly from the main part. Operating temperature range is not specified. RoHS compliance is confirmed with UL94 V-0 rating. Current rating is not specified.

N3432-6002RB (3M 3000 Series): Offers the highest current rating at 1.75A, exceeding the main part's 1A specification. Features push-pull fastening and mounting flange. Operating temperature range is -55°C to 105°C, which is 20°C lower than the main part's upper limit. RoHS compliance is confirmed with UL94 V-0 rating.

All substitute parts carry REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating, matching the main part specifications.

Frequently Asked Questions (FAQ)

Q: Can the 09185406924 be used as a direct replacement for CWN-562-40-0000?

A: Yes. The 09185406924 meets all critical substitution parameters including 40-position, 2-row configuration, 0.100" pitch, through-hole mounting, shrouded 4-wall construction, and solder termination. Both parts maintain identical mating contact length (0.240") and insulation height (0.681"). ROHS3 compliance and UL94 V-0 flammability rating are confirmed for both.

Q: What are the differences between the 71918-040LF and the main part?

A: The 71918-040LF differs in packaging (tube versus bulk), fastening type (push-pull versus latch lock/eject hooks), and contact length specifications. Mating contact length is 0.228" versus 0.240" for the main part. Operating temperature range is not specified for the 71918-040LF. All core connector parameters remain compatible.

Q: Is the N3432-6002RB suitable for high-temperature applications?

A: The N3432-6002RB operates from -55°C to 105°C, which is 20°C lower than the CWN-562-40-0000 upper operating limit of 125°C. For applications requiring operation above 105°C, the main part or the 09185406924 (rated to 125°C) should be selected.

Q: What is the difference in current rating between these parts?

A: The CWN-562-40-0000 is rated for 1A. The N3432-6002RB is rated for 1.75A, providing higher current capacity. Current ratings are not specified for the 09185406924 and 71918-040LF in available documentation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 09185406924 is ROHS3 compliant. The 71918-040LF and N3432-6002RB are RoHS compliant. All parts meet regulatory requirements for lead-free construction.

Q: What packaging options are available?

A: The CWN-562-40-0000, 09185406924, and N3432-6002RB are supplied in bulk packaging. The 71918-040LF is supplied in tube packaging. Packaging selection may affect handling and storage procedures.
