CWN-310-26-0021 Equivalent & Substitute Parts

Part Overview

The CWN-310-26-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 26-position connector operates across -55°C to 125°C and features gold-plated mating contacts with nickel-plated posts. The part maintains active product status with 719 units in current inventory. Substitute parts are identified to address supply chain requirements, inventory availability, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 65823-169 (Amphenol ICC/FCI Quickie™ series) qualifies as an equivalent based on the following critical parameters:

• 26-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing
• Male pin header with circular contact geometry
• Through-hole, right-angle mounting with shrouded 4-wall design
• Solder termination with phosphor bronze alloy contact material
• Board-to-cable/wire application style
• UL94 V-0 flammability rating
• Moisture Sensitivity Level 1 (Unlimited)

Substitution is valid where these core parameters align. Variations in contact length, insulation height, fastening mechanism, and compliance certifications do not preclude functional equivalence in applications where the primary electrical and mechanical interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

Selection between CWN-310-26-0021 and 65823-169 depends on compliance and supply requirements:

CWN-310-26-0021 (CW Industries): Active product status with ROHS3 compliance and REACH unaffected designation. Suitable for applications requiring full RoHS3 certification and REACH compliance documentation. Current inventory of 719 units supports immediate procurement.

65823-169 (Amphenol ICC/FCI): Active product status with RoHS non-compliant designation and REACH affected status. Suitable for applications where RoHS3 compliance is not required. Higher inventory availability (1,028 units) may support extended supply chain requirements. Fastening mechanism differs (Latch Lock/Eject Hooks, Short vs. Push-Pull), requiring mechanical compatibility verification in the mating connector interface.

Both parts meet UL94 V-0 flammability requirements and operate within equivalent electrical parameters for standard 26-position, 2.54mm pitch applications.

Frequently Asked Questions (FAQ)

Q: Can 65823-169 directly replace CWN-310-26-0021 in all applications?

A: Electrical and mechanical compatibility is established for the core 26-position, 2.54mm pitch header interface. However, the fastening mechanism differs (Latch Lock/Eject Hooks, Short vs. Push-Pull). Verify that the mating connector accommodates the substitute fastening type before implementation.

Q: What are the compliance differences between these parts?

A: CWN-310-26-0021 is ROHS3 compliant and REACH unaffected. The 65823-169 is RoHS non-compliant and REACH affected. Applications requiring RoHS3 certification must use CWN-310-26-0021.

Q: Are the contact lengths interchangeable?

A: Contact lengths differ slightly (CWN-310-26-0021: 0.240" mating / 0.155" post; 65823-169: 0.230" mating / 0.105" post). These variations fall within acceptable tolerances for standard 2.54mm pitch header applications but should be verified against specific mating connector specifications.

Q: What is the difference in insulation material?

A: CWN-310-26-0021 uses thermoplastic insulation; 65823-169 uses polyester glass-filled insulation. Both achieve UL94 V-0 flammability rating. Material selection does not affect electrical performance in standard applications.

Q: Which part should be selected for new designs?

A: For new designs requiring regulatory compliance, CWN-310-26-0021 is recommended due to ROHS3 and REACH compliance. For applications without compliance constraints, either part is functionally equivalent based on core electrical and mechanical parameters.

Q: Are there packaging differences?

A: CWN-310-26-0021 packaging is not specified in available data. 65823-169 is supplied in bulk packaging. Confirm packaging requirements with supplier specifications.
