Key Parameters

Substitute Part Grouping Explanation

Substitution of the 749084-9 D-Type Plug connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector style (D-Type)
• Connector type (Plug, Male Pins)
• Number of positions (100)
• Number of rows (2)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)
• Contact finish (Gold)
• Current rating (1A)
• Voltage rating (30V)
• Operating temperature range (-55°C to 105°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Flange feature (Housing/Shell 4-40)
• Series designation (AMPLIMITE .050 III)
• Shielded construction

Material and Certification Parameters:

• Contact material (Phosphor Bronze)
• Dielectric material (Liquid Crystal Polymer, Polyester)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1)

The substitute part 5749084-9 maintains full equivalence across all electrical, mechanical, and material parameters. The primary distinction between the main part and substitute relates to product status compliance and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 5749084-9 substitute part provides full functional and mechanical equivalence to the 749084-9 across all electrical parameters, connector geometry, and material specifications. Both parts are classified as obsolete products within the AMPLIMITE .050 III series.

Compliance Considerations:

The 5749084-9 offers improved regulatory compliance status compared to the main part. The substitute achieves ROHS3 compliance and REACH unaffected status, whereas the 749084-9 is RoHS non-compliant and REACH affected. For applications subject to environmental regulations or procurement policies requiring RoHS3 compliance, the 5749084-9 is the appropriate selection.

Packaging Difference:

The 5749084-9 is supplied in tube packaging, whereas the main part packaging specification is not provided. Packaging selection should be based on assembly process requirements and inventory management protocols.

Inventory Availability:

Current stock levels indicate 1126 pieces of the 5749084-9 substitute part available, compared to 813 pieces of the main part 749084-9. Both parts are new original stock.

For applications where regulatory compliance is not a constraint, either part satisfies the electrical and mechanical requirements. For new designs or systems requiring compliance documentation, the 5749084-9 is the preferred selection.

Frequently Asked Questions (FAQ)

Q: Are the 749084-9 and 5749084-9 electrically interchangeable?

A: Yes. Both parts are 100 position D-Type plugs with identical electrical ratings (1A current, 30V voltage), operating temperature range (-55°C to 105°C), and contact specifications. They are fully electrically interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (tube for 5749084-9 versus unspecified for 749084-9), RoHS compliance status (ROHS3 compliant for 5749084-9 versus non-compliant for 749084-9), and REACH regulatory status (unaffected for 5749084-9 versus affected for 749084-9). All connector specifications, dimensions, and electrical parameters are identical.

Q: Can I use the 5749084-9 as a direct replacement for the 749084-9 in existing assemblies?

A: Yes. The 5749084-9 is mechanically and electrically identical to the 749084-9. It features the same right-angle through-hole mounting, solder termination, 0.050 pitch layout, and shielded construction. Direct substitution is supported.

Q: Why would I choose the 5749084-9 over the 749084-9?

A: The 5749084-9 should be selected when RoHS3 compliance or REACH unaffected status is required by procurement specifications, environmental regulations, or customer requirements. For applications without such constraints, either part is functionally equivalent.

Q: Are there any compatibility issues with PCB layouts designed for the 749084-9?

A: No. Both parts share identical connector geometry, pin pitch (0.050), row spacing (0.100), and mounting configuration. PCB layouts designed for the 749084-9 accommodate the 5749084-9 without modification.

Q: What is the significance of the tube packaging for the 5749084-9?

A: Tube packaging affects handling, storage, and assembly line integration. Tube packaging is suitable for automated pick-and-place operations and provides organized component storage. Selection between packaging formats depends on assembly process requirements and inventory management systems.

Q: Both parts are listed as obsolete. What does this mean for long-term availability?

A: Obsolete status indicates these parts are no longer in active production. Current inventory levels (813 pieces for 749084-9 and 1126 pieces for 5749084-9) represent available stock from existing supplies. For applications requiring long-term component availability, evaluation of current-production D-Type connector alternatives within the AMPLIMITE series or other connector families is recommended.

Q: Are the contact materials and dielectric specifications identical?

A: Yes. Both parts use phosphor bronze contacts with gold finish and employ liquid crystal polymer (LCP) and polyester dielectric materials. Material flammability rating (UL94 V-0) and moisture sensitivity level (MSL 1) are identical.
