CWN-300-26-0021 Equivalent & Substitute Parts

Part Overview

The CWN-300-26-0021 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 706 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-300-26-0021 is determined by strict alignment of the following parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (26)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Circular)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1 - Unlimited)

The substitute part 65823-169 from Amphenol ICC (FCI) meets all critical mechanical and electrical parameters required for direct substitution in applications designed for the CWN-300-26-0021.

Parameter Comparison

Engineering Selection Recommendations

The CWN-300-26-0021 maintains active product status with established inventory availability. The substitute part 65823-169 provides functional equivalence across all critical mechanical and electrical parameters.

Compliance considerations: The CWN-300-26-0021 is ROHS3 compliant and REACH unaffected. The 65823-169 is RoHS non-compliant and REACH affected. Selection between these parts must account for end-application regulatory requirements. Applications subject to RoHS3 or REACH restrictions require the CWN-300-26-0021. Applications without such constraints may utilize either part based on availability and supply chain considerations.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, supporting equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can 65823-169 be used as a direct replacement for CWN-300-26-0021 in all applications?

A: Direct substitution is mechanically and electrically valid. However, regulatory compliance must be verified. The CWN-300-26-0021 is ROHS3 compliant; the 65823-169 is not. Applications requiring RoHS3 compliance cannot use the substitute part.

Q: What are the key differences between these two connectors?

A: Both parts share identical pitch, position count, mounting configuration, and shrouding. Minor variations exist in contact length specifications (mating contact: 0.240" vs. 0.230"; post contact: 0.090" vs. 0.105") and insulation height (0.291" vs. 0.305"). These dimensional differences do not affect mating compatibility when used in equivalent applications.

Q: Are there fastening differences between these connectors?

A: Yes. The CWN-300-26-0021 uses push-pull fastening. The 65823-169 uses latch lock/eject hooks with short configuration. Mating connector compatibility must be verified for the specific application.

Q: What is the significance of the contact finish options?

A: Both parts specify 30.0µin (0.76µm) gold plating on mating contacts. The 65823-169 offers an optional GXT™ gold finish variant. Standard gold finish is equivalent between both parts for electrical performance.

Q: How do compliance ratings affect part selection?

A: The CWN-300-26-0021 is ROHS3 compliant and REACH unaffected, suitable for regulated markets. The 65823-169 is RoHS non-compliant and REACH affected. End-product regulatory requirements determine which part is acceptable.

Q: Are inventory levels a consideration for substitution?

A: Current inventory shows 706 units of CWN-300-26-0021 and 1028 units of 65823-169 in stock. Availability may influence sourcing decisions when supply constraints exist.
