Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0039000090 is determined by strict equivalence across the following parameters:

• Manufacturer: Molex
• Series: Mini-Fit Jr 5556
• Contact Type: Socket
• Wire Gauge: 16 AWG
• Contact Termination: Crimp
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Electrical Classification: Power
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute part 0039000089 meets all electrical and mechanical parameters required for direct substitution. The primary difference between the main part and substitute is packaging configuration (Bulk versus Cut Tape), which does not affect functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0039000090 and 0039000089 are active products with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The 0039000090 is supplied in Bulk packaging, while the 0039000089 is supplied in Cut Tape (CT) packaging. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications. The choice between these substitutes does not introduce any functional or performance trade-offs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0039000089 be used as a direct replacement for the 0039000090?

A: Yes. Both parts are identical in electrical and mechanical specifications, including wire gauge, contact finish, termination method, and series classification. The only difference is packaging format.

Q: What is the significance of the packaging difference between Bulk and Cut Tape?

A: Packaging format affects handling, storage, and assembly processes but does not alter the functional or electrical properties of the contact. Bulk packaging is typically used for high-volume applications, while Cut Tape packaging is suited for automated pick-and-place assembly systems.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0039000090 and 0039000089 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What wire gauge compatibility do these contacts support?

A: Both contacts are rated for 16 AWG wire gauge with crimp termination, ensuring consistent electrical performance and mechanical retention across applications.

Q: Is there an inventory advantage to selecting one part over the other?

A: The 0039000089 (Cut Tape) has higher inventory availability (20,525 pcs) compared to the 0039000090 (Bulk, 6,698 pcs). Selection should align with supply chain requirements and assembly methodology.
