Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors in the Mini-Fit Jr 87427 series is determined by strict equivalence across the following critical parameters:

• Connector geometry: 20 positions, 2 rows, 0.165" (4.20mm) pitch and row spacing
• Mounting configuration: Through hole, right-angle orientation
• Electrical interface: Male pin contact type with shrouded 4-wall design
• Material and finish specifications: Brass contacts with tin plating, polyamide insulation
• Termination method: Solder attachment
• Compliance standards: ROHS3 compliance and UL94 V-0 flammability rating

The substitute part 0874272002 maintains identical electrical and mechanical specifications across all these parameters. The primary distinction is product status and packaging format, with 0874272002 classified as active and supplied in tray packaging, whereas 0874272003 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874272002 is a direct functional equivalent to the obsolete 0874272003. Both parts are ROHS3 compliant and carry identical UL94 V-0 flammability certification. The 0874272002 is the recommended selection for new designs and replacement applications due to its active product status and assured long-term availability. The tray packaging of 0874272002 is standard for production environments and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can 0874272002 be used as a direct replacement for 0874272003 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector geometry, contact configuration, termination method, and material specifications. The substitution is direct with no design modifications required.

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

A: The 0874272003 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 0874272002 maintains active status with ongoing production and supply chain support, making it the appropriate choice for sustained component sourcing.

Q: Are there packaging considerations when switching from 0874272003 to 0874272002?

A: The 0874272003 packaging is not specified in the available data. The 0874272002 is supplied in tray packaging, which is standard for production quantities and does not affect connector performance or PCB assembly compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the 0874272003 and 0874272002 are ROHS3 compliant and carry UL94 V-0 flammability certification. MSL rating is 1 (Unlimited) for both parts.

Q: What are the critical parameters that define substitution eligibility for this connector?

A: Substitution is valid when the following parameters match: 20-position, 2-row configuration; 0.165" (4.20mm) pitch and row spacing; through-hole right-angle mounting; shrouded 4-wall design; male pin contacts; solder termination; brass contacts with tin plating; and polyamide insulation material.
