Substitute Part Grouping Explanation

The Molex 0444720883 has one direct substitute: the 0444720850. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count and row configuration (8 positions, 2 rows)
• Mating pitch and row spacing (0.165" / 4.20mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)
• Insulation material (Polyamide PA66, Nylon 6/6)
• Contact finish (Tin)
• Series designation (Mini-Fit HCS 44472)

The substitute part maintains identical mechanical and electrical interface specifications, ensuring direct compatibility in board-level applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0444720850 is the direct active equivalent for the obsolete 0444720883. Both parts maintain identical mechanical and electrical interface specifications within the Mini-Fit HCS 44472 series. The substitute part is currently in active production status with higher inventory availability.

Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, suitable for standard storage and handling conditions. The primary difference is the material flammability rating: the main part carries UL94 V-0 certification while the substitute carries UL94 V-2. The substitute is supplied in tray packaging, whereas the main part packaging specification is not provided.

For applications requiring the specific UL94 V-0 flammability rating, the original part number should be retained if available. For general-purpose applications across automotive, industrial, medical, and telecommunications sectors, the 0444720850 provides direct functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0444720850 be used as a direct replacement for the 0444720883?

A: Yes. Both parts are from the same Mini-Fit HCS 44472 series and share identical specifications for connector type, contact configuration, pitch, mounting method, shrouding, and fastening mechanism. The 0444720850 is the active production equivalent.

Q: What is the difference between the two parts?

A: The primary differences are product status (0444720883 is obsolete; 0444720850 is active), material flammability rating (V-0 versus V-2), and packaging format (unspecified versus tray). All mechanical and electrical interface parameters are identical.

Q: Does the flammability rating difference affect compatibility?

A: The flammability rating difference does not affect mechanical or electrical compatibility. Selection should be based on application-specific flammability requirements. Applications requiring UL94 V-0 certification must use the original part number if available.

Q: Are there any packaging considerations when switching to the substitute part?

A: The 0444720850 is supplied in tray packaging. Verify that tray packaging is compatible with your assembly and handling processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0444720883 and 0444720850 are ROHS3 compliant and carry identical moisture sensitivity level (MSL 1 - Unlimited) classifications.

Q: What is the pitch specification for these connectors?

A: Both parts feature a 0.165" (4.20mm) mating pitch with 0.165" (4.20mm) row spacing, configured as 8 positions in 2 rows.
