Substitute Part Grouping Explanation

Substitution eligibility for the CWN-562-50-0021 is determined by strict alignment of the following core parameters:

Connector Type: Header (male pin contact type)
Position Count & Row Configuration: 50 positions, 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting Method: Through-hole solder termination
Shrouding Configuration: Shrouded 4-wall design

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full RoHS compliance. Selection between the CWN-562-50-0021 and its equivalents should be based on the following factors:

CWN-562-50-0021 (CW Industries): Circular contact geometry with nickel post finish. Operating temperature extends to 125°C. Current rating specified at 1A. Suitable for applications requiring the specific contact shape and extended thermal performance.

09185506924 (HARTING): Square contact geometry with tin post finish. Maintains 125°C upper temperature limit. Includes mounting flange feature. ROHS3 compliant. Suitable where square contact geometry and mounting flange integration are advantageous.

71918-050LF (Amphenol ICC): Square contact geometry with GXT™ gold mating finish and tin post finish. Quickie™ series designation. Includes mounting flange. REACH Affected status noted. Highest inventory availability (1555 pcs). Suitable for applications prioritizing contact finish specification and flange mounting.

N3433-6002RB (3M): Square contact geometry with tin post finish. Operating temperature upper limit 105°C. Current rating 1.75A. Shorter post length (0.112"). ROHS compliant. Suitable for applications with lower thermal requirements but higher current capacity.

N3433-6003RB (3M): Square contact geometry with tin post finish. Operating temperature upper limit 105°C. Current rating 1.75A. Extended post length (0.155"), matching CWN-562-50-0021 post dimension. ROHS compliant. Suitable for applications requiring extended post length with higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CWN-562-50-0021 with any of the listed parts without PCB redesign?

A: Yes. All substitute parts maintain identical pitch (0.100"/2.54mm), position count (50), row configuration (2 rows), mounting type (through-hole solder), and shrouding (4-wall). PCB footprints remain compatible. Contact shape variation (circular vs. square) does not affect hole pattern compatibility.

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

A: Both parts are electrically and mechanically equivalent with identical pitch, position count, and row spacing. The primary difference is post length: N3433-6002RB has 0.112" post length, while N3433-6003RB has 0.155" post length. Selection depends on PCB thickness and solder joint requirements. N3433-6003RB post length matches the CWN-562-50-0021 specification.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is a design parameter, not a substitution barrier. The CWN-562-50-0021 and HARTING 09185506924 both support -55°C to 125°C. The 3M parts (N3433-6002RB and N3433-6003RB) support -55°C to 105°C. Selection should align with application thermal requirements. Lower temperature-rated parts are suitable for applications not requiring 125°C operation.

Q: What packaging formats are available?

A: CWN-562-50-0021 packaging is not specified. HARTING 09185506924 is supplied in Bulk packaging. Amphenol ICC 71918-050LF is supplied in Tube packaging. 3M parts (N3433-6002RB and N3433-6003RB) are supplied in Bulk packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Are all parts RoHS compliant?

A: Yes. CWN-562-50-0021, HARTING 09185506924, and both 3M parts are RoHS compliant. Amphenol ICC 71918-050LF is RoHS Compliant with REACH Affected status. All parts meet RoHS requirements for lead-free solder applications.

Q: What is the difference in contact finish between parts?

A: CWN-562-50-0021 uses gold mating finish with nickel post finish. All substitute parts use gold mating finish with tin post finish. Gold mating finish ensures consistent contact resistance and corrosion resistance across all options. Post finish variation (nickel vs. tin) does not affect mating performance but may influence solder joint characteristics during assembly.

Q: Which part has the highest current rating?

A: The 3M parts (N3433-6002RB and N3433-6003RB) both support 1.75A current rating, compared to 1A for the CWN-562-50-0021. Current rating is specified for the connector as a whole, not per-contact. Selection should align with total circuit current requirements.
