Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 748394-6 are identified based on strict electrical and mechanical parameter compatibility. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector type: D-Sub, high-density receptacle with female sockets
• Position count: 62 positions
• Row configuration: 3 rows
• Shell size and layout: 4 (DC, C) high density
• Mounting orientation: Right angle
• Termination method: Solder
• Flange feature: Mating side, female screwlock (4-40)
• Shell material and finish: Steel, nickel plated
• Contact finish: Gold
• Operating temperature range: -55°C to 105°C
• Flammability rating: UL94 V-0

Allowable Parameter Variations: Substitute parts may differ in current rating (provided minimum rating meets or exceeds 2A), voltage rating (provided minimum rating meets or exceeds 125V), contact finish thickness specifications, dielectric material composition, contact material composition, and regulatory compliance status (RoHS, REACH).

Engineering Selection Recommendations

NorComp 181-062-213R561 is the primary substitute for the TE Connectivity 748394-6. This part maintains all critical mechanical and electrical parameters, including 62-position configuration, 3-row layout, shell size 4 (DC, C) high-density specification, right-angle solder termination, and female screwlock flange feature. The NorComp substitute provides enhanced electrical performance with 3A current rating and 250V voltage rating, exceeding the original part specifications. The part carries active product status and ROHS3 compliance, addressing regulatory requirements for new applications. Operating temperature range and flammability rating remain equivalent to the original part.

Mercury United 634-062-663-043 provides an alternative substitute with confirmed mechanical compatibility in connector type, position count, row configuration, shell size, mounting orientation, termination method, and flange feature. Complete electrical specifications for this part are not provided in available documentation. This part is suitable for applications where detailed electrical parameter verification through manufacturer documentation is feasible.

For applications requiring regulatory compliance with modern standards, the NorComp 181-062-213R561 is the recommended selection due to active product status and ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the Mercury United 634-062-663-043 be used as a direct replacement for the TE Connectivity 748394-6?

A: The Mercury United 634-062-663-043 shares all critical mechanical parameters with the TE Connectivity 748394-6, including connector type, position count, row configuration, shell size, mounting type, termination method, and flange feature. However, complete electrical specifications for the Mercury United part are not documented. Verification of current and voltage ratings through manufacturer documentation is required before selection.

Q: What are the key differences between the NorComp 181-062-213R561 and the original TE Connectivity 748394-6?

A: The NorComp 181-062-213R561 maintains all critical mechanical and electrical parameters. Documented differences include: current rating of 3A versus 2A on the original part, voltage rating of 250V versus 125V on the original part, active product status versus obsolete status, ROHS3 compliance versus RoHS non-compliance, and additional panel mount capability. These differences represent enhancements or expanded functionality rather than incompatibilities.

Q: Are there packaging differences between the substitute parts and the original?

A: The TE Connectivity 748394-6 packaging is not specified in available documentation. The NorComp 181-062-213R561 is supplied in tray packaging. The Mercury United 634-062-663-043 packaging is not specified. Packaging specifications should be confirmed with suppliers for procurement and assembly planning purposes.

Q: What is the significance of the "Board Lock" feature on the original part?

A: The TE Connectivity 748394-6 includes a board lock feature. The NorComp 181-062-213R561 includes both board lock and shielding features. The Mercury United 634-062-663-043 feature set is not fully documented. The board lock feature provides mechanical retention during assembly and operation. Confirmation of feature presence on substitute parts is necessary for applications where this mechanical function is required.

Q: Can these connectors be used interchangeably in existing designs?

A: The NorComp 181-062-213R561 provides full mechanical and electrical compatibility with the TE Connectivity 748394-6 based on documented parameters. The Mercury United 634-062-663-043 provides mechanical compatibility with undocumented electrical specifications. Both parts maintain the same connector type, position count, row configuration, shell size, mounting orientation, termination method, and flange feature. Interchangeability is confirmed for the NorComp part; the Mercury United part requires electrical specification verification.

Q: What compliance certifications should be considered when selecting a substitute?

A: The original TE Connectivity 748394-6 is RoHS non-compliant. The NorComp 181-062-213R561 carries ROHS3 compliance certification and is REACH unaffected. For applications subject to RoHS or REACH regulations, the NorComp substitute addresses these requirements. The Mercury United 634-062-663-043 compliance status is not documented. Regulatory requirements for the target application should be confirmed before final part selection.
