Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOLC-150-31-L-Q are identified based on strict equivalence across the following critical parameters:

• Number of Positions: 200
• Number of Rows: 4
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Current Rating: 2.6A per Contact
• Operating Temperature: -55°C ~ 125°C
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variations in secondary features such as fastening mechanisms or board-level enhancements do not preclude substitution when all primary electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the MOLC-150-31-L-Q and MOLC-150-31-L-Q-LC maintain Active product status with full compliance to ROHS3 standards and UL94 V-0 flammability ratings. The parts are electrically and mechanically equivalent across all primary specifications. The MOLC-150-31-L-Q-LC includes Board Lock functionality as an additional feature. Selection between these parts should be based on application requirements for board-level retention mechanisms and current inventory availability.
