CWN-300-10-0021 Equivalent & Substitute Parts

Part Overview

The CWN-300-10-0021 is a rectangular connector header manufactured by CW Industries, designed for through-hole, right-angle board-to-cable/wire applications. This shrouded 10-position header with 2.54mm pitch is an active product with 729 units in stock. 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 design requirements permit alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 65823-049 (Amphenol ICC/FCI, Quickie™ series) qualifies as an equivalent based on the following critical parameters:

Matching electrical and mechanical specifications include: connector type (header), contact type (male pin), mating pitch (0.100"/2.54mm), number of positions (10), number of rows (2), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), shrouding (shrouded 4-wall), termination method (solder), contact shape (circular), contact finish on mating surface (gold), contact material (phosphor bronze alloy), flammability rating (UL94 V-0), insulation color (blue), and moisture sensitivity level (1/Unlimited).

Minor dimensional variations exist in contact lengths and insulation height; however, these fall within acceptable tolerances for board-to-cable/wire interconnect applications. The substitute employs an alternative fastening mechanism (latch lock/eject hooks versus push-pull) and differs in insulation material composition (polyester, glass-filled versus thermoplastic), which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The CWN-300-10-0021 is the primary specification for applications requiring ROHS3 compliance and REACH unaffected status. This part maintains active product status with adequate inventory availability.

The 65823-049 substitute is functionally equivalent for board-to-cable/wire interconnect applications where the core electrical and mechanical parameters align. However, design teams must account for the following compliance differences:

The substitute part is RoHS non-compliant and REACH affected, making it unsuitable for applications subject to European Union regulatory requirements or customer specifications mandating RoHS3 compliance. Organizations operating under ROHS3 or REACH compliance obligations must source the primary CWN-300-10-0021 part.

For applications without regulatory compliance constraints, the substitute offers equivalent performance based on matching connector geometry, contact configuration, and material specifications. The alternative fastening mechanism (latch lock/eject hooks) and insulation material composition (polyester, glass-filled) do not compromise functional interchangeability in standard through-hole solder applications.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution eligibility for the CWN-300-10-0021?

A: Substitution is based on matching connector type (header), contact type (male pin), mating pitch (0.100"/2.54mm), number of positions (10), number of rows (2), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), shrouding (shrouded 4-wall), termination method (solder), contact shape (circular), contact finish (gold), contact material (phosphor bronze), and flammability rating (UL94 V-0).

Q: Can the 65823-049 be used as a direct replacement in all applications?

A: The 65823-049 is functionally equivalent for standard board-to-cable/wire interconnect applications. However, applications requiring ROHS3 compliance or REACH unaffected status must use the primary CWN-300-10-0021 part, as the substitute is RoHS non-compliant and REACH affected.

Q: What is the difference in fastening mechanisms between these parts?

A: The CWN-300-10-0021 uses a push-pull fastening type, while the 65823-049 employs latch lock/eject hooks. Both mechanisms provide secure mating and demating in board-to-cable/wire applications.

Q: Are there dimensional differences between the main part and substitute?

A: Minor dimensional variations exist. The contact length on the mating side differs by 0.010" (0.26mm), the post contact length differs by 0.015" (0.38mm), and the insulation height differs by 0.014" (0.35mm). These variations fall within acceptable tolerances for standard interconnect applications.

Q: What is the inventory status for both parts?

A: The CWN-300-10-0021 has 729 units in stock. The 65823-049 substitute has 638 units in stock, both listed as new original inventory.

Q: How do the insulation materials differ?

A: The CWN-300-10-0021 uses thermoplastic insulation, while the 65823-049 uses polyester, glass-filled insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for standard through-hole solder applications.
