Substitute Part Grouping Explanation

Substitution eligibility for the CWN-362-50-0021 is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Row Configuration: 50 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Shrouding & Mounting: Shrouded 4-wall design with through-hole mounting

Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet UL94 V-0 flammability requirements with MSL 1 (Unlimited) moisture sensitivity classification. Selection among these alternatives should be based on the following factors:

Temperature Range Consideration: The CWN-362-50-0021 and HARTING 09185506924 support the full -55°C to 125°C operating range. The 3M parts (D3433-6002-AR, N3433-6002RB, N3433-6003RB) are rated to -55°C to 105°C, which is suitable for applications not requiring the extended upper temperature limit.

RoHS Compliance: CW Industries CWN-362-50-0021, HARTING 09185506924, and 3M D3433-6002-AR carry ROHS3 Compliant designation. HARTING 09185506924, 3M N3433-6002RB, and N3433-6003RB carry RoHS Compliant status. Amphenol ICC 71918-050LF carries RoHS Compliant status with REACH Affected designation.

Contact Post Length Variation: The CWN-362-50-0021 and 3M N3433-6003RB feature 0.155" (3.94mm) contact post length. HARTING 09185506924, Amphenol ICC 71918-050LF, and 3M D3433-6002-AR and N3433-6002RB feature shorter post lengths of 0.114" to 0.112" (2.84mm to 2.90mm). Post length selection depends on PCB thickness and solder joint requirements.

Fastening Mechanism: The CWN-362-50-0021 uses Latch Lock/Eject Hooks with Long configuration. All substitute parts employ Push-Pull fastening, which represents a functional difference in mating/unmating operation.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CWN-362-50-0021 with any of the listed parts without PCB redesign?

A: Yes, all substitute parts share identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), position count (50), and shrouded 4-wall configuration. However, contact post length variations (0.112" to 0.155") may require PCB hole depth verification. The fastening mechanism differs (Latch Lock/Eject Hooks versus Push-Pull), which affects connector handling but not electrical compatibility.

Q: What is the difference between the 3M parts N3433-6002RB and N3433-6003RB?

A: Both parts are identical except for contact post length. N3433-6002RB features 0.112" (2.84mm) post length, while N3433-6003RB features 0.155" (3.94mm) post length, matching the CWN-362-50-0021 specification. Selection depends on PCB thickness and solder joint design requirements.

Q: Does the HARTING 09185506924 meet the same temperature range as the CWN-362-50-0021?

A: Yes, both parts are rated for -55°C to 125°C operating temperature. The 3M substitute parts are rated to -55°C to 105°C, which is suitable for applications not requiring the extended upper temperature limit of 125°C.

Q: What packaging options are available for these substitute parts?

A: CWN-362-50-0021 packaging is not specified. HARTING 09185506924 is supplied in Bulk packaging. Amphenol ICC 71918-050LF is supplied in Tube packaging. 3M D3433-6002-AR is supplied in Tray packaging. 3M N3433-6002RB and N3433-6003RB are supplied in Bulk packaging. Packaging selection affects handling, storage, and assembly line integration.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts carry either ROHS3 Compliant or RoHS Compliant designation. The CWN-362-50-0021, HARTING 09185506924, and 3M D3433-6002-AR carry ROHS3 Compliant status. Amphenol ICC 71918-050LF, 3M N3433-6002RB, and N3433-6003RB carry RoHS Compliant status. Amphenol ICC 71918-050LF is additionally marked as REACH Affected.

Q: What is the current rating difference between the CWN-362-50-0021 and the 3M substitute parts?

A: The CWN-362-50-0021 is rated for 1A per contact. The 3M parts (D3433-6002-AR, N3433-6002RB, N3433-6003RB) are rated for 1.75A per contact. HARTING 09185506924 and Amphenol ICC 71918-050LF do not specify current rating. Higher current rating in 3M parts provides additional design margin for high-current applications.
