Substitute Part Grouping Explanation

Substitution eligibility for the CWN-362-10-0021 is determined by strict alignment of the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Number of Positions: 10
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Shrouding: Shrouded - 4 Wall
Termination: Solder
Material Flammability Rating: UL94 V-0

All three identified substitute parts (71918-010LF, D3793-6002-AR, N3793-6002RB) meet these core electrical and mechanical requirements. Variations in secondary parameters such as contact finish thickness, fastening type, and insulation material do not preclude substitution when primary interface specifications remain equivalent.

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS regulations. The CWN-362-10-0021 and D3793-6002-AR both achieve ROHS3 compliance, while 71918-010LF and N3793-6002RB meet RoHS requirements. Selection between these parts depends on application-specific thermal and current requirements:

For applications requiring the full -55°C to 125°C operating range, the CWN-362-10-0021 remains the primary choice. The 3M D3793-6002-AR and N3793-6002RB parts operate to 105°C maximum, suitable for applications with lower thermal headroom requirements. The Amphenol ICC 71918-010LF does not specify operating temperature limits and should be evaluated against specific application constraints.

Current rating considerations: The CWN-362-10-0021 is rated for 1A, while D3793-6002-AR and N3793-6002RB support 1.75A. The 71918-010LF does not specify current rating. Applications requiring sustained currents above 1A should prioritize the 3M alternatives.

Frequently Asked Questions (FAQ)

Q: Can 71918-010LF replace CWN-362-10-0021 in all applications?

A: The 71918-010LF meets all core mechanical and electrical interface requirements. However, it does not specify operating temperature or current rating limits. Applications with defined thermal or current constraints require verification against the Amphenol ICC datasheet before substitution.

Q: What is the difference between D3793-6002-AR and N3793-6002RB?

A: Both are 3M 10-position 2.54mm pitch headers with identical mechanical interfaces. The primary differences are packaging format (D3793-6002-AR ships in trays; N3793-6002RB in bulk) and contact finish thickness on the post (D3793-6002-AR: 39.4µin; N3793-6002RB: 200.0µin). Electrical and mechanical performance are equivalent.

Q: Does the CWN-362-10-0021 have a higher operating temperature than the 3M alternatives?

A: Yes. The CWN-362-10-0021 operates from -55°C to 125°C, while D3793-6002-AR and N3793-6002RB operate to 105°C maximum. Applications requiring operation above 105°C must use the CW Industries part.

Q: Are all substitute parts UL94 V-0 rated?

A: Yes. All four parts (CWN-362-10-0021, 71918-010LF, D3793-6002-AR, and N3793-6002RB) meet UL94 V-0 flammability requirements.

Q: What packaging options are available?

A: CWN-362-10-0021 packaging is not specified. 71918-010LF is supplied in tubes, D3793-6002-AR in trays, and N3793-6002RB in bulk. Packaging selection depends on assembly process requirements and inventory management practices.

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

A: Yes, provided the application does not exceed the thermal or current limits of the selected substitute. All parts share identical 2.54mm pitch, 10-position, 2-row configuration and through-hole mounting interface. Mechanical fit and electrical connectivity are equivalent.
