CWN-300-20-0021 Equivalent & Substitute Parts

Part Overview

The CWN-300-20-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 20-position header with 2.54mm pitch and male pin contacts operates across -55°C to 125°C and is actively produced. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 65823-067 (Amphenol ICC/FCI) qualifies as an equivalent based on the following critical parameters:

• Identical mating pitch: 0.100" (2.54mm)
• Identical number of positions: 20
• Identical row configuration: 2 rows
• Identical row spacing: 0.100" (2.54mm)
• Identical mounting style: Through hole, right angle
• Identical shrouding: Shrouded - 4 wall
• Identical termination method: Solder
• Identical contact shape: Circular
• Identical insulation color: Blue
• Identical material flammability rating: UL94 V-0
• Identical connector type: Header with male pin contacts
• Identical board-to-cable/wire style

These parameters define the mechanical and electrical interchangeability envelope for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The CWN-300-20-0021 is the primary specification. The substitute part 65823-067 is suitable for applications requiring equivalent mechanical and electrical performance.

The CWN-300-20-0021 maintains active product status and is ROHS3 compliant with REACH unaffected classification. The 65823-067 is also active but is RoHS non-compliant and REACH affected. Selection between these parts depends on regulatory requirements specific to the end application and target market.

Both parts share identical critical parameters: mating pitch, position count, row configuration, mounting orientation, shrouding design, termination method, and flammability rating. Contact length specifications differ slightly between the two parts (mating contact length: 0.240" vs. 0.230"; post contact length: 0.090" vs. 0.105"), and insulation height varies (0.291" vs. 0.305"). These dimensional variations are within typical manufacturing tolerances for this connector category and do not affect functional interchangeability in standard applications.

Frequently Asked Questions (FAQ)

Q: What makes 65823-067 a suitable substitute for CWN-300-20-0021?

A: Both connectors share identical mating pitch (2.54mm), position count (20), row configuration (2 rows), mounting style (through-hole right angle), shrouding (4-wall), termination method (solder), contact shape (circular), and flammability rating (UL94 V-0). These parameters define mechanical and electrical compatibility for board-to-cable/wire applications.

Q: Are there differences in contact dimensions between these parts?

A: Yes. The mating contact length differs (CWN-300-20-0021: 0.240"; 65823-067: 0.230"), and post contact length differs (CWN-300-20-0021: 0.090"; 65823-067: 0.105"). Insulation height also varies (CWN-300-20-0021: 0.291"; 65823-067: 0.305"). These variations are within standard manufacturing tolerances and do not affect functional interchangeability.

Q: What is the difference in compliance status between these parts?

A: The CWN-300-20-0021 is ROHS3 compliant and REACH unaffected. The 65823-067 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations must use the CWN-300-20-0021.

Q: Do both parts support the same current rating?

A: The CWN-300-20-0021 specifies a 1A current rating. The 65823-067 does not provide a current rating specification in the available data. Verify current requirements with the connector manufacturer if the 65823-067 is selected.

Q: What is the fastening mechanism difference?

A: The CWN-300-20-0021 uses push-pull fastening. The 65823-067 uses latch lock/eject hooks. Both are mechanical fastening systems suitable for shrouded headers.

Q: Are the insulation materials the same?

A: No. The CWN-300-20-0021 uses thermoplastic insulation. The 65823-067 uses polyester with glass filling. Both materials meet UL94 V-0 flammability requirements.
