Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0874271003 is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Mini-Fit Jr 87427 header with male pin contacts
• Position Configuration: 10 positions in 2-row arrangement
• Pitch Specifications: 0.165" (4.20mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding & Fastening: 4-wall shrouded design with locking ramp fastening
• Contact & Material Specifications: Tin-plated brass contacts, polyamide insulation
• Compliance Standards: UL94 V-0 flammability rating, ROHS3 compliance, REACH unaffected status

The substitute part 0874271002 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being packaging format and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874271002 is the direct functional equivalent for the obsolete 0874271003. Both parts are manufactured by Molex within the Mini-Fit Jr 87427 series and maintain identical electrical and mechanical specifications. The 0874271002 is currently in active production status with substantial inventory availability (17,307 pcs), whereas the 0874271003 is obsolete with limited remaining stock (1,134 pcs).

Both parts satisfy identical compliance requirements: ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability rating. The primary operational difference is packaging format (tray for 0874271002 versus unspecified for 0874271003), which does not affect connector performance or board-level compatibility.

For new designs and ongoing production requiring this connector configuration, the 0874271002 is the appropriate selection due to active product status and assured supply chain continuity.

Frequently Asked Questions (FAQ)
