Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444720502 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch specification (0.165" / 4.20mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)
• Insulation material (Polyamide PA66, Nylon 6/6)
• Flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The substitute part 0444720504 maintains full equivalence across all these parameters. The primary distinction is the contact finish specification on the mating surface and the product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0444720504 is the direct active equivalent for the obsolete 0444720502. Both components maintain identical mechanical and electrical interface specifications within the Mini-Fit HCS 44472 series. The transition from gold to tin contact finish on the mating surface represents a manufacturing update while preserving functional compatibility. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, supporting continued use in automotive, industrial, medical, and telecommunications applications. The 0444720504 is recommended for new designs and replacement applications where the 0444720502 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 0444720504 directly replace the 0444720502 in existing assemblies?

A: Yes. Both connectors maintain identical pitch (0.165" / 4.20mm), position count (5), mounting method (through-hole), shrouding configuration (4-wall), and termination approach (solder). The contact finish difference does not affect mechanical or electrical interface compatibility.

Q: What is the significance of the contact finish change from gold to tin?

A: The mating contact finish change from gold (30.0µin) to tin (100.0µin) represents a manufacturing specification update. Both finishes provide adequate corrosion resistance and electrical conductivity for the specified applications. The tin finish maintains the same contact resistance characteristics required for the connector interface.

Q: Are there packaging differences between these parts?

A: The 0444720502 packaging specification is not provided. The 0444720504 is supplied in Tray packaging. Confirm packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0444720502 and 0444720504 are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Why is the 0444720502 listed as obsolete?

A: The 0444720502 has been superseded by the 0444720504 within the Mini-Fit HCS 44472 series. The 0444720504 is the active production equivalent and is recommended for all new applications.
