Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0039310049 is determined by strict alignment of the following critical parameters:

• Mating pitch of 0.165" (4.20mm)
• 4-position, 2-row configuration
• Right-angle through-hole mounting
• Shrouded 4-wall design
• Solder termination with locking ramp fastening
• Square contact geometry
• Polyamide/Nylon insulation material
• Brass or brass alloy contact material
• UL94 V-2 flammability rating
• RoHS compliance status
• MSL 1 rating

The TE Connectivity AMP Connectors part number 1586043-4 meets all these criteria and is classified as a manufacturer-recommended equivalent. Both parts share identical mechanical interfaces and electrical termination methods, enabling direct substitution in applications where the connector footprint and mating interface are the primary design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0039310049 and TE Connectivity 1586043-4 are Active status products with full RoHS compliance and UL94 V-2 flammability certification. The TE Connectivity 1586043-4 is designated as the manufacturer-recommended equivalent and carries additional electrical ratings (9A current, 600VAC voltage) and operating temperature specification (-40°C ~ 105°C), providing documented performance parameters for applications requiring these specifications.

Selection between these parts should be based on availability, supply chain requirements, and any application-specific electrical or thermal performance needs. Both parts satisfy identical mechanical and interface requirements for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1586043-4 be used as a direct replacement for the Molex 0039310049?

A: Yes. Both connectors share identical mating pitch (0.165" / 4.20mm), position count (4), row configuration (2), mounting style (through-hole right-angle), shrouding design (4-wall), and termination method (solder with locking ramp). The mechanical interface and PCB footprint are compatible for direct substitution.

Q: Are there differences in insulation height between these parts?

A: The Molex 0039310049 has an insulation height of 0.378" (9.60mm), while the TE Connectivity 1586043-4 measures 0.386" (9.80mm). This 0.008" (0.20mm) difference is within typical manufacturing tolerances and does not affect mechanical compatibility or mating interface performance.

Q: What is the significance of the insulation color difference?

A: The Molex part features black insulation, while the TE Connectivity part has natural (undyed) insulation. This is a cosmetic difference with no impact on electrical or mechanical function. Selection may depend on visual identification requirements or assembly documentation standards.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-2 rated, MSL 1, and RoHS compliant. The Molex part is ROHS3 compliant, while the TE Connectivity part is RoHS compliant. Both carry EAR99 ECCN classification and 8536.69.4040 HTSUS code. Compliance requirements for your specific application should be verified against your design documentation.

Q: What contact finish specifications apply to these connectors?

A: Both parts feature tin-plated contacts on both mating and post surfaces. The Molex part specifies 100.0µin (2.54µm) finish thickness, while the TE Connectivity part specifies 80.0µin (2.03µm). Both thicknesses provide adequate corrosion protection and solderability for standard PCB assembly processes.
