CWN-552-26-0000 Equivalent & Substitute Parts

Part Overview

The CWN-552-26-0000 is a rectangular connector header manufactured by CW Industries, designed for through-hole mounting applications. This 26-position, 2-row connector operates at 0.100" (2.54mm) pitch and supports board-to-cable/wire connections with solder termination. The part is active in production and ROHS3 compliant. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements where alternative fastening mechanisms or contact post lengths are acceptable within the electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the CWN-552-26-0000 is determined by strict equivalence in the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Number of Positions: 26
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with ROHS3 or RoHS standards. The CWN-552-26-0000 and 09185266924 support the full operating temperature range of -55°C to 125°C, while N3429-6002RB and N3429-6003RB operate within -55°C to 105°C. Selection should account for application temperature requirements.

The primary differences among substitutes are contact post length and fastening mechanism. The CWN-552-26-0000 features latch lock/eject hooks with a 0.090" post length, while HARTING 09185266924 uses push-pull fastening with 0.114" post length, and 3M parts use push-pull fastening with 0.112" (N3429-6002RB) or 0.155" (N3429-6003RB) post lengths. These variations require PCB design accommodation but do not affect electrical compatibility within the specified parameters.

All parts carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification, ensuring equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can N3429-6002RB and N3429-6003RB be used interchangeably with CWN-552-26-0000?

A: Both 3M parts are electrically and mechanically compatible substitutes. The primary difference is contact post length: N3429-6002RB has 0.112" posts while N3429-6003RB has 0.155" posts. Selection depends on PCB hole depth and solder joint requirements. Both operate at -55°C to 105°C, which is narrower than the CWN-552-26-0000 range of -55°C to 125°C.

Q: What is the difference between the fastening mechanisms?

A: The CWN-552-26-0000 uses latch lock/eject hooks with long engagement, while 09185266924, N3429-6002RB, and N3429-6003RB use push-pull fastening. Both mechanisms provide secure mating but require different connector housing designs. Fastening type does not affect electrical performance.

Q: Are all substitute parts ROHS compliant?

A: Yes. CWN-552-26-0000, 09185266924, and N3429-6003RB are ROHS3 compliant. N3429-6002RB is RoHS compliant. All meet environmental regulatory requirements.

Q: Does contact shape variation affect compatibility?

A: The CWN-552-26-0000 has circular contacts while all substitutes have square contacts. Both shapes are compatible with standard 0.100" pitch mating connectors. Contact shape does not affect electrical performance or mating compatibility.

Q: What is the current rating difference between parts?

A: CWN-552-26-0000 is rated at 1A per contact. 09185266924 does not specify current rating. N3429-6002RB and N3429-6003RB are rated at 1.75A per contact. Applications requiring higher current capacity should use the 3M parts.
