Key Parameters

Substitute Part Grouping Explanation

Substitution between Molex 0874270643 and 0874270642 is valid based on identical alignment across all critical electrical and mechanical parameters. Both components share the same series designation (Mini-Fit Jr 87427), connector architecture, contact configuration, and physical dimensions. The substitution criteria are determined by the following parameters:

• Connector Type: Header (identical)
• Contact Type: Male Pin (identical)
• Position Configuration: 6 positions, 2 rows (identical)
• Pitch Specifications: 0.165" (4.20mm) mating pitch and row spacing (identical)
• Mounting and Termination: Through-hole solder termination (identical)
• Shrouding Design: Shrouded - 4 Wall (identical)
• Contact Materials and Finishes: Brass with tin plating (identical)
• Insulation Specifications: Polyamide (PA46), Nylon 4/6, UL94 V-0 rated (identical)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (identical)

The primary distinction is product status: 0874270643 is obsolete while 0874270642 maintains active status with higher inventory availability (2866 pcs vs. 939 pcs).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874270642 is the direct functional equivalent for applications currently specified with part number 0874270643. Selection of 0874270642 is supported by:

Frequently Asked Questions (FAQ)

Q: Can Molex 0874270642 be used as a direct replacement for 0874270643 in existing assemblies?

A: Yes. Both components are identical in all electrical and mechanical parameters including connector type, contact configuration, pitch spacing, mounting method, and material specifications. The only difference is product status and packaging format.

Q: What is the significance of the product status difference between these parts?

A: The 0874270643 is classified as obsolete, indicating Molex has discontinued active production and support. The 0874270642 maintains active status with current manufacturing and supply chain support. For ongoing production requirements, the active part number should be specified.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both components share identical dimensions including 0.165" (4.20mm) pitch spacing, 0.504" (12.80mm) insulation height, 0.130" (3.30mm) post length, and through-hole mounting configuration. PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and rated UL94 V-0 for material flammability. Moisture sensitivity level is identical at MSL 1 (Unlimited). No compliance trade-offs exist between the two part numbers.

Q: What is the difference in packaging between these parts?

A: The 0874270643 packaging is not specified in available data. The 0874270642 is supplied in bulk packaging. Packaging format does not affect component performance or compatibility; it relates only to order quantity and handling procedures.
