Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874272403 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact material and finish (Brass with Tin plating)
• Insulation material (Polyamide PA46, Nylon 4/6)

The substitute part 0874272402 maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (Active vs. Obsolete) and packaging format (Tray vs. unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874272402 is a direct functional equivalent to the 0874272403. Both parts are ROHS3 compliant and maintain identical electrical and mechanical specifications. The primary distinction is product status: the 0874272403 is obsolete while the 0874272402 is active in production. For new designs or component replenishment, the 0874272402 is the appropriate selection due to its active status and significantly higher inventory availability (10,672 units vs. 838 units). Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity rating, ensuring compliance with industrial and telecommunications applications.
