Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0734152240 is determined by strict equivalence across the following parameters:

• Connector style (MCX) and type (Plug, Male Pin)
• Electrical impedance (50 Ohms)
• Termination methods (Solder for center contact, Crimp for shield)
• Mounting configuration (Free Hanging/In-Line)
• Fastening mechanism (Snap-On)
• Maximum frequency rating (6 GHz minimum)
• Voltage rating (335 V minimum)
• Regulatory compliance (RoHS3)

The Samtec MCX-P-C-H-ST-CA2 meets all these criteria and is classified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0734152240 and Samtec MCX-P-C-H-ST-CA2 are active products with full RoHS3 compliance and identical electrical and mechanical specifications. Selection between these parts may be based on:

• Inventory availability (Molex: 692 pcs; Samtec: 1,241 pcs)
• Supply chain preferences or existing vendor relationships
• Cable group compatibility (Molex supports RD-316; Samtec supports RG-178)
• Operating temperature range requirements (Molex: -55°C to 155°C; Samtec: -65°C to 125°C)
• Package contents (Molex includes 3 pcs; Samtec includes 5 pcs)

Both parts satisfy the core functional and compliance requirements for 50-ohm MCX plug applications at frequencies up to 6 GHz.

Frequently Asked Questions (FAQ)

Q: What makes the Samtec MCX-P-C-H-ST-CA2 a valid substitute for the Molex 0734152240?
