Substitute Part Grouping Explanation

Substitution eligibility for the CWN-562-26-0021 is determined by strict alignment of the following critical parameters:

Connector positioning: 26 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
Physical mounting: Through-hole solder termination with shrouded 4-wall construction
Environmental compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1 rating
Operating range: -55°C to 105°C minimum (CWN-562-26-0021 operates to 125°C)
Contact configuration: Male pin headers with gold-plated mating surfaces

The three identified substitute parts (09185266924, N3429-6002RB, N3429-6003RB) meet these core substitution criteria. Variations in contact post length, contact finish materials, fastening mechanisms, and insulation materials do not preclude substitution when the primary electrical and mechanical interfaces remain compatible.

Engineering Selection Recommendations

All four parts maintain active production status with full RoHS and MSL compliance. The CWN-562-26-0021 and HARTING 09185266924 support the extended operating temperature range of -55°C to 125°C, while the 3M N3429-6002RB and N3429-6003RB are rated to -55°C to 105°C. Selection between these parts depends on application temperature requirements.

The CWN-562-26-0021 and N3429-6003RB share identical contact post length (0.155" / 3.94mm), while the HARTING 09185266924 and 3M N3429-6002RB feature shorter post lengths (0.114" and 0.112" respectively). Post length differences affect PCB stack-up and mating depth considerations in board design.

Contact finish materials vary: the CWN-562-26-0021 uses nickel-plated posts, while all substitute parts use tin-plated posts. All parts maintain gold-plated mating surfaces. These material selections do not affect electrical substitutability for standard applications.

Frequently Asked Questions (FAQ)

Q: Can N3429-6002RB replace CWN-562-26-0021 in applications requiring 125°C operation?

A: No. The N3429-6002RB is rated to -55°C to 105°C maximum. For applications requiring 125°C operation, use CWN-562-26-0021 or HARTING 09185266924, both rated to -55°C to 125°C.

Q: What is the significance of contact post length differences between these parts?

A: Contact post length (0.155", 0.114", or 0.112") determines the mating depth and PCB stack-up clearance. Shorter posts (09185266924, N3429-6002RB) reduce overall connector height, while longer posts (CWN-562-26-0021, N3429-6003RB) provide greater engagement depth. Selection depends on PCB thickness and available mating space.

Q: Are all substitute parts ROHS3 compliant?

A: CWN-562-26-0021, HARTING 09185266924, and 3M N3429-6003RB are ROHS3 compliant. The 3M N3429-6002RB carries RoHS compliance without the "3" designation. Both compliance levels meet current regulatory requirements.

Q: Does the difference between nickel and tin post finishes affect electrical performance?

A: No. Both nickel and tin post finishes provide equivalent electrical conductivity and solder joint reliability for standard applications. The choice reflects manufacturing process differences between manufacturers and does not impact substitutability.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the application does not exceed 105°C and the PCB design accommodates the specific contact post length of the selected part. All parts share identical mating pitch (0.100"), row spacing (0.100"), position count (26), and shrouded 4-wall construction.
