Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-310-20-0000 is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (20 positions, 2 rows)
• Pitch specifications (0.100" / 2.54mm mating pitch and row spacing)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Circular)
• Flammability rating (UL94 V-0)
• Operating temperature range (-55°C ~ 125°C)

The substitute part 65823-067 (Amphenol ICC / FCI, Quickie™ series) meets these core electrical and mechanical requirements, enabling functional equivalence in applications requiring a 20-position, 2.54mm pitch rectangular connector header with right-angle through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the CWN-310-20-0000 and 65823-067 are active production parts meeting UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The primary compliance distinction is RoHS status: the CWN-310-20-0000 is ROHS3 compliant, while the 65823-067 is RoHS non-compliant. Applications requiring RoHS3 compliance must use the CWN-310-20-0000. The 65823-067 is REACH Affected, whereas the CWN-310-20-0000 is REACH Unaffected. Selection between these parts depends on regulatory requirements specific to the end application and target market. Both parts share identical core electrical and mechanical parameters, supporting functional interchangeability in applications without RoHS or REACH restrictions.

Frequently Asked Questions (FAQ)

Q: What determines if 65823-067 can substitute for CWN-310-20-0000?

A: Substitution is valid when the connector maintains identical pitch (0.100" / 2.54mm), position count (20), row configuration (2 rows), mounting style (through-hole right-angle), shrouding design (4-wall), and contact specifications (male pin, circular, solder termination). Both parts meet these criteria.

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

A: Yes. The CWN-310-20-0000 has a contact length - mating of 0.240" (6.10mm) and contact length - post of 0.155" (3.94mm). The 65823-067 has a contact length - mating of 0.230" (5.84mm) and contact length - post of 0.105" (2.67mm). These dimensional variations may affect mechanical fit in constrained applications.

Q: What is the difference in insulation material?

A: The CWN-310-20-0000 uses thermoplastic insulation, while the 65823-067 uses polyester with glass filling. Both materials meet UL94 V-0 flammability requirements. The glass-filled polyester in the 65823-067 provides enhanced mechanical rigidity.

Q: Which part should be selected for RoHS-compliant applications?

A: The CWN-310-20-0000 is ROHS3 compliant and must be used for applications requiring RoHS certification. The 65823-067 is RoHS non-compliant and is not suitable for such applications.

Q: Are there fastening type differences?

A: Yes. The CWN-310-20-0000 uses push-pull fastening, while the 65823-067 uses latch lock/eject hooks. This difference affects mating and unmating procedures and may impact connector reliability in applications requiring frequent disconnection cycles.

Q: What is the contact finish thickness difference?

A: The CWN-310-20-0000 has a mating contact finish thickness of 10.0µin (0.25µm) and post finish thickness of 50.0µin (1.27µm). The 65823-067 specifies 30.0µin (0.76µm) for mating contact finish, with post finish thickness not specified. These variations may affect long-term contact resistance and wear characteristics.
