Key Parameters

Substitute Part Grouping Explanation

The Curtis Industries 325010-11-0 qualifies as a direct substitute based on the following critical parameters:

• Circuit Configuration: Both parts provide 11 circuits with identical 0.325" (8.26mm) pitch spacing
• Electrical Ratings: Matching 15A current rating and 300V voltage rating
• Wire Gauge Compatibility: Both accept 14-22 AWG wire
• Termination Method: Identical screw-top and PC pin-bottom configuration
• Barrier Construction: Both employ dual-wall (2 Wall) barrier design
• Mounting Interface: Both support chassis and panel mounting with through-hole installation
• Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited) rating

Substitution is valid when the application requirements align with these core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0387006111 and Curtis Industries 325010-11-0 are active production components with ROHS3 compliance and identical MSL ratings. Selection between these parts should be based on:

Molex 0387006111: Select when the application requires operation down to -40°C minimum temperature or when thermoplastic insulation material is specified in design requirements. Current inventory of 966 units supports immediate availability.

Curtis Industries 325010-11-0: Select when the application requires UL94 V-0 flammability certification or when polypropylene insulation material is preferred. The part is rated to -105°C maximum operating temperature. Inventory of 730 units is available.

Both parts meet the core electrical and mechanical requirements for 11-circuit barrier block applications with 15A/300V ratings and identical pitch and termination specifications.
