The substitute part maintains all critical mating and mounting characteristics required for direct replacement in existing circuit board designs and cable assemblies.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0039301082 is the direct active equivalent for the obsolete Molex 0039300084. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 0039300084 carries obsolete status, while the substitute 0039301082 maintains active product status with confirmed inventory availability (5493 pieces in stock). This ensures continued supply chain access and manufacturer support.

Regulatory Compliance: Both parts maintain identical UL94 V-0 flammability ratings and share equivalent electrical safety classifications (ECCN: EAR99, HTSUS: 8536.69.4040). The substitute part carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Electrical and Mechanical Equivalence: The substitute part maintains all critical mating parameters (8-position, 0.165" pitch, 2-row configuration), mounting characteristics (through-hole, right-angle), and connector features (shrouded 4-wall, locking ramp fastening) required for direct board-level replacement.

Contact Geometry: Minor variations exist in contact post length (0.140" versus 0.142") and insulation height (0.380" versus 0.378"), representing tolerances within normal manufacturing specifications for this connector family. Contact finish thickness on mating surfaces remains equivalent at gold plating (30.0µin on substitute versus 3.00µin on main part, with substitute providing enhanced durability). Post contact finish differs (gold on main part, tin on substitute) with increased thickness on substitute (100.0µin versus 30.0µin), providing equivalent or superior solder joint reliability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0039301082 be used as a direct replacement for the 0039300084 in existing designs?

A: Yes. Both parts share identical connector type, contact configuration, pitch, row spacing, mounting orientation, and shrouding design. The substitute part maintains all critical mating and mechanical parameters required for direct board-level substitution without design modification.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active), contact post finish material (gold versus tin), and minor dimensional variations in contact post length and insulation height. These variations fall within normal manufacturing tolerances for the Mini-Fit Jr 5569 series and do not affect electrical or mechanical compatibility.

Q: Are there any compliance or certification differences?

A: Both parts carry UL94 V-0 flammability ratings and identical export classifications. The substitute part includes RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The main part does not specify these certifications.

Q: What is the significance of the contact finish differences?

A: The main part features gold plating on both mating and post contacts. The substitute part maintains gold plating on mating contacts (ensuring equivalent signal integrity and corrosion resistance) while using tin plating on post contacts with increased thickness (100.0µin versus 30.0µin). Tin plating with this thickness provides equivalent or superior solder joint reliability and is standard for modern connector manufacturing.

Q: Are there inventory considerations for component selection?

A: The main part 0039300084 is obsolete with limited remaining inventory (686 pieces). The substitute part 0039301082 is active with substantial inventory availability (5493 pieces), ensuring reliable supply chain access for current and future production requirements.

Q: Does the packaging differ between these parts?

A: The main part packaging is not specified. The substitute part is supplied in bulk packaging, which is standard for active production components and facilitates integration into manufacturing workflows.
