Substitute Part Grouping Explanation

The Molex 0039302047 has been identified with one active equivalent: Molex 0039302041. Substitution is valid based on the following critical parameters that remain identical between the main part and substitute:

• Series designation: Mini-Fit Jr 5566
• Connector type: Header with male pin contacts
• Position count: 4 positions in single row configuration
• Mating pitch: 0.165" (4.20mm)
• Mounting method: Through hole with solder termination
• Shrouding configuration: Shrouded with 4-wall design
• Fastening mechanism: Locking ramp
• Contact materials and finishes: Brass with gold mating finish and tin post finish
• Insulation specifications: Polyamide (PA66), Nylon 6/6 with natural color
• Mechanical dimensions: Insulation height 0.504" (12.80mm), contact post length 0.138" (4.60mm)
• Compliance certifications: UL94 V-2, ROHS3 Compliant, REACH Unaffected

The primary distinction is product status: the main part is obsolete while the substitute is active, with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0039302041 is the direct functional equivalent for the obsolete Molex 0039302047. Both components maintain identical electrical and mechanical specifications within the Mini-Fit Jr 5566 series. The substitute part carries active product status with substantially higher inventory availability, making it the appropriate selection for new designs and ongoing procurement requirements.

Both parts maintain equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected, and UL94 V-2 flammability rating. The moisture sensitivity level of 1 (Unlimited) applies to both components, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0039302041 be used as a direct replacement for the 0039302047 in existing designs?

A: Yes. The 0039302041 is functionally identical to the 0039302047 across all electrical and mechanical parameters. Both components share the same series designation, connector type, position count, pitch, mounting method, contact materials, and compliance certifications. The substitute part is suitable for direct replacement in board-to-cable/wire applications.

Q: What is the primary difference between these two part numbers?

A: The main difference is product status. The 0039302047 is classified as obsolete, while the 0039302041 is active. Additionally, the 0039302041 is available in bulk packaging with significantly higher inventory levels (22448 units versus 1034 units).

Q: Are the contact finishes and materials identical?

A: Yes. Both parts feature brass contacts with gold plating on mating surfaces (30.0µin thickness) and tin plating on solder posts (100.0µin thickness). The contact shape, insulation material (Polyamide PA66/Nylon 6/6), and all dimensional specifications are identical.

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

A: Yes. Both the 0039302047 and 0039302041 are ROHS3 Compliant, REACH Unaffected, and carry a UL94 V-2 material flammability rating. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: Is there any difference in the shrouding or fastening mechanism?

A: No. Both parts feature identical 4-wall shrouding and locking ramp fastening type. The board lock feature is present on both components.

Q: What applications are these connectors suitable for?

A: Both parts are designated for General Purpose, Industrial, and Telecommunications applications. The through-hole solder termination and board lock feature make them suitable for permanent board-level connections in these sectors.
