Parameter Comparison

Engineering Selection Recommendations

The CWN-301-10-0021 is the primary specification for applications requiring ROHS3 compliance and REACH unaffected status. Both parts are active products with equivalent electrical and mechanical performance characteristics.

The substitute part 65823-049 is suitable for applications where RoHS3 compliance is not mandated and REACH affected status is acceptable. Selection between these parts should be based on regulatory requirements specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Can 65823-049 be used as a direct replacement for CWN-301-10-0021?

A: Yes, for applications where RoHS3 compliance and REACH unaffected status are not required. Both parts share identical mating pitch (0.100"), position count (10), row configuration (2 rows), mounting type (through hole, right angle), shrouding (4 wall), and contact geometry (circular male pins with gold mating finish at 30.0µin thickness).

Q: What are the key differences between these parts?

A: The primary differences are regulatory compliance and insulation material composition. CWN-301-10-0021 is ROHS3 compliant with REACH unaffected status and uses thermoplastic insulation. The 65823-049 is RoHS non-compliant with REACH affected status and uses polyester glass-filled insulation. Both maintain UL94 V-0 flammability rating and identical electrical performance.

Q: Are the contact dimensions interchangeable?

A: Contact length specifications differ slightly. CWN-301-10-0021 has mating contact length of 0.240" (6.10mm) and post length of 0.090" (2.29mm). The 65823-049 has mating contact length of 0.230" (5.84mm) and post length of 0.105" (2.67mm). These minor variations do not affect mating compatibility with standard 0.100" pitch receptacles.

Q: What is the inventory status for each part?

A: CWN-301-10-0021 has 1109 units in stock. The 65823-049 has 638 units in stock.

Q: Are both parts suitable for the same operating temperature range?

A: CWN-301-10-0021 is rated for -55°C ~ 125°C. Operating temperature range is not specified for 65823-049 in the provided data.
