Substitute Part Grouping Explanation

Substitute part 65823-067 (Amphenol ICC/FCI Quickie™ series) qualifies as an equivalent based on the following critical parameters:

Matching electrical and mechanical specifications: 20-position, 2-row configuration with 0.100" (2.54mm) mating pitch and row spacing; male pin contact type; through-hole, right-angle mounting; shrouded 4-wall design; solder termination; circular contact shape; phosphor bronze alloy contact material; UL94 V-0 flammability rating; blue insulation color; and MSL 1 rating.

Substitution is valid where these core parameters align. Variations in contact length dimensions, insulation material composition, fastening hook design, and compliance certifications must be evaluated against specific application requirements.

Engineering Selection Recommendations

Both CWN-302-20-0021 and 65823-067 maintain active product status and meet core electrical and mechanical requirements for 20-position, 2.54mm pitch header applications.

CWN-302-20-0021 is ROHS3 compliant and REACH unaffected, making it the preferred selection for applications subject to European Union environmental regulations or customer-mandated RoHS requirements.

65823-067 is RoHS non-compliant and REACH affected. Selection of this substitute requires confirmation that the application environment permits non-compliant components or that exemptions apply.

Minor dimensional variations exist: contact length mating (0.240" vs. 0.230"), contact length post (0.090" vs. 0.105"), and insulation height (0.291" vs. 0.305"). Insulation material differs (thermoplastic vs. polyester glass-filled). These variations must be evaluated against PCB layout constraints, mating connector specifications, and thermal/mechanical stress requirements.

Frequently Asked Questions (FAQ)

Q: Can 65823-067 be used as a direct replacement for CWN-302-20-0021?

A: Both connectors share identical pitch (2.54mm), position count (20), row configuration (2), mounting type (through-hole right-angle), and shrouding (4-wall). Substitution is mechanically and electrically feasible where dimensional tolerances and compliance certifications are acceptable to the application.

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

A: Primary differences include RoHS/REACH compliance status (CWN-302-20-0021 is compliant; 65823-067 is not), insulation material composition (thermoplastic vs. polyester glass-filled), contact length dimensions, insulation height, and fastening hook design. Contact finish options also differ slightly (standard gold vs. gold or GXT™).

Q: Are there packaging or inventory considerations?

A: CWN-302-20-0021 is available in 966 units (new original stock). 65823-067 is available in 775 units (bulk packaging). Packaging format and inventory levels should be confirmed against procurement requirements.

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

A: CWN-302-20-0021 is ROHS3 compliant and REACH unaffected, making it suitable for applications requiring environmental compliance certification. 65823-067 does not meet these standards.

Q: Do the dimensional differences affect PCB design?

A: Contact length and insulation height variations (0.009" to 0.014" differences) may impact mating connector clearance, PCB trace routing, and stacking height calculations. Design verification is required when substituting between these parts.

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

A: CWN-302-20-0021 specifies -55°C to 125°C operation. Operating temperature for 65823-067 is not provided in available specifications. Thermal performance must be confirmed for temperature-critical applications.
