Molex 0444830004 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0444830004 is a shrouded right-angle header connector with 4 positions and 0.165" (4.20mm) pitch, designed for through-hole board-to-cable/wire applications. This connector features a Mini-Fit TPA 44483 series design with male pin contacts, gold-plated mating surfaces, and tin-plated posts for solder termination.

The 0444830004 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444830004 is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 4
• Number of Rows: 2
• Pitch - Mating: 0.165" (4.20mm)
• Row Spacing - Mating: 0.165" (4.20mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Contact Material: Brass
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The Molex 0039301042 meets all critical substitution criteria. Both connectors share identical mating pitch, row configuration, shrouding design, contact materials, and regulatory compliance. The substitute part is from the Mini-Fit Jr 5569 series and maintains full electrical and mechanical compatibility with the original 0444830004 specification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0039301042 is the qualified substitute for the obsolete 0444830004. Both parts maintain identical electrical and mechanical interface specifications, ensuring direct compatibility in board-to-cable/wire applications.

The substitute part is currently in active production status, providing assured component availability and supply chain continuity. Both connectors carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, telecommunications, and automotive applications.

The 0039301042 features polyamide (PA66) nylon 6/6 insulation material compared to the polyester insulation of the original part. Both materials meet UL94 V-0 flammability requirements. The substitute part has a reduced insulation height (0.378" versus 0.461") and shorter contact post length (0.142" versus 0.163"), which may require PCB layout verification for clearance and solder joint depth in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0039301042 directly replace the 0444830004 in existing designs?

A: The 0039301042 maintains identical mating pitch (0.165"), row spacing, shrouding configuration, and contact materials. However, the reduced insulation height and shorter post length require verification that PCB footprints and clearances accommodate these dimensional differences.

Q: What is the primary reason for substitution?

A: The 0444830004 is classified as obsolete. The 0039301042 is an active production part from Molex that meets all critical electrical and mechanical interface requirements.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Regulatory compliance is equivalent.

Q: What is the difference in insulation material?

A: The original part uses polyester insulation, while the substitute uses polyamide (PA66) nylon 6/6. Both materials meet UL94 V-0 requirements. Polyamide offers improved mechanical strength and thermal performance.

Q: Are there packaging differences?

A: The 0444830004 packaging information is not specified in the original data. The 0039301042 is supplied in bulk packaging.

Q: What dimensional changes should be considered?

A: The substitute part has an insulation height of 0.378" (9.60mm) compared to 0.461" (11.70mm) for the original, and a contact post length of 0.142" (3.60mm) compared to 0.163" (4.15mm). These differences may affect PCB layout and solder joint formation.
