Substitute Part Grouping Explanation

Substitution eligibility for the CWN-502-50-0021 is determined by strict alignment of the following critical parameters:

Primary Matching Criteria (Non-Negotiable):

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 50
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Style: Board to Cable/Wire or Board to Board or Cable

Secondary Compatibility Parameters:

• Operating Temperature Range: -55°C minimum and 125°C maximum or equivalent
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 or equivalent
• Moisture Sensitivity Level: 1 (Unlimited)

All three identified substitute parts (09185506923, D3433-5002-AR, N3433-5002RB) meet these primary and secondary criteria, confirming their functional and regulatory equivalence to the main part.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 or RoHS compliance and MSL 1 (Unlimited) ratings, confirming regulatory and environmental equivalence to the CWN-502-50-0021.

09185506923 (HARTING SEK Series): This part maintains the full operating temperature range of -55°C to 125°C and offers the closest thermal specification match. It is available in bulk packaging with 746 pcs in stock. The push-pull fastening mechanism differs from the main part's latch lock design but provides equivalent mechanical retention for through-hole applications.

D3433-5002-AR (3M D3000 Series): This part is supplied in tray packaging with 843 pcs in stock. The operating temperature range is limited to -55°C to 105°C, which is 20°C lower than the main part's maximum. Current rating is specified at 1.75A, exceeding the main part's 1A rating. The push-pull fastening mechanism and mounting flange features provide alternative mechanical engagement options.

N3433-5002RB (3M 3000 Series): This part is available in bulk packaging with 1041 pcs in stock. Operating temperature range is -55°C to 105°C. Current rating is 1.75A. The style designation includes "Board to Board or Cable" compatibility, providing broader application flexibility. RoHS compliance is confirmed without specific ROHS3 designation.

Selection should prioritize the main part (CWN-502-50-0021) for applications requiring the full -55°C to 125°C operating range. The HARTING 09185506923 is the preferred substitute when thermal performance matching is critical. The 3M parts (D3433-5002-AR and N3433-5002RB) are suitable for applications with maximum operating temperatures not exceeding 105°C.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09185506923 be used as a direct replacement for the CWN-502-50-0021?

A: Yes. Both parts share identical mating pitch (0.100"), row spacing (0.100"), position count (50), row count (2), mounting type (through-hole right-angle), shrouding (4-wall), and termination method (solder). Both maintain the full -55°C to 125°C operating temperature range and UL94 V-0 flammability rating. The fastening mechanism differs (push-pull versus latch lock), but both provide equivalent mechanical retention for through-hole solder applications.

Q: What is the temperature limitation of the 3M substitute parts?

A: Both 3M parts (D3433-5002-AR and N3433-5002RB) have a maximum operating temperature of 105°C, compared to the main part's 125°C maximum. These parts are suitable for applications where the maximum operating temperature does not exceed 105°C. Applications requiring sustained operation above 105°C should use the CWN-502-50-0021 or the HARTING 09185506923.

Q: Are there packaging differences between the substitute parts?

A: Yes. The CWN-502-50-0021 is supplied in unspecified packaging. The HARTING 09185506923 is supplied in bulk packaging. The 3M D3433-5002-AR is supplied in tray packaging. The 3M N3433-5002RB is supplied in bulk packaging. Packaging selection should align with procurement and assembly workflow requirements.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The CWN-502-50-0021, HARTING 09185506923, and 3M D3433-5002-AR are ROHS3 compliant. The 3M N3433-5002RB is RoHS compliant. All parts meet RoHS environmental and regulatory requirements.

Q: What is the difference between the fastening mechanisms?

A: The CWN-502-50-0021 uses latch lock/eject hooks with long engagement. The HARTING 09185506923 and both 3M parts use push-pull fastening. Both mechanisms provide secure mechanical retention for through-hole solder termination. The choice between mechanisms depends on mating connector design and assembly procedure requirements.

Q: Are the contact materials interchangeable?

A: All parts feature gold-plated mating contacts, ensuring equivalent electrical performance. Post contact finishes differ: the main part uses nickel, while substitutes use tin. Contact base materials vary (phosphor bronze, copper alloy, brass), but all are suitable for 0.100" pitch applications. Material differences do not affect functional compatibility for standard through-hole solder applications.

Q: Which substitute part offers the highest current rating?

A: Both 3M parts (D3433-5002-AR and N3433-5002RB) are rated for 1.75A, compared to the main part's 1A rating. The HARTING 09185506923 does not specify a current rating. For applications requiring current ratings above 1A, the 3M parts provide additional capacity.
