Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Type connectors is determined by strict equivalence across the following critical parameters:

Connector Architecture Parameters:

• Connector style (D-Type)
• Connector type (Plug with male pins)
• Number of positions (50)
• Number of rows (2)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)

Electrical Parameters:

• Current rating (1A)
• Voltage rating (30V)
• Contact finish (Gold)
• Contact material (Phosphor Bronze)

Mechanical Parameters:

• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Flange feature (Housing/Shell with 4-40 specification)
• Shielded construction

Environmental & Compliance Parameters:

• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Dielectric material composition (Liquid Crystal Polymer, Polyester)

The substitute part 5749084-5 maintains complete equivalence across all these parameters, with the primary distinction being packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The substitute part 5749084-5 provides complete functional and mechanical equivalence to the main part 749084-5. All critical electrical parameters, connector geometry, termination method, and environmental specifications are identical. This part is suitable for direct substitution in existing designs and applications.

Compliance Considerations:

The substitute part 5749084-5 carries RoHS Compliant status, whereas the main part 749084-5 lists RoHS status as not applicable. For applications subject to RoHS regulations or requiring RoHS-compliant components, the substitute part 5749084-5 is the appropriate selection.

Packaging Differences:

The substitute part 5749084-5 is supplied in tube packaging, whereas the main part packaging format is not specified. Packaging selection should be based on assembly process requirements and inventory management protocols.

Obsolescence Status:

Both parts are classified as obsolete. Component selection should prioritize availability and lead time considerations. Current inventory levels indicate 1581 pieces of the substitute part 5749084-5 are available, compared to 809 pieces of the main part 749084-5.

Frequently Asked Questions (FAQ)

Q: Can 5749084-5 be used as a direct replacement for 749084-5 in existing assemblies?

A: Yes. The substitute part 5749084-5 maintains complete equivalence across all functional, electrical, and mechanical parameters. Pin configuration, connector geometry, solder termination, electrical ratings, and environmental specifications are identical.

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

A: The primary differences are packaging format (tube for 5749084-5 versus unspecified for 749084-5) and RoHS compliance status (RoHS Compliant for 5749084-5 versus not applicable for 749084-5). All connector specifications and electrical characteristics are identical.

Q: Are both parts from the same manufacturer?

A: Yes. Both 749084-5 and 5749084-5 are manufactured by TE Connectivity AMP Connectors and belong to the AMPLIMITE .050 III series.

Q: What does the 50-position configuration mean?

A: The connector accommodates 50 signal contacts arranged in 2 rows with 0.050-inch pitch spacing between contacts and 0.100-inch spacing between rows. This is the standard D-Type 50-position layout.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 105°C and carry a UL94 V-0 flammability rating, indicating suitability for industrial and demanding thermal environments.

Q: What is the current-carrying capacity of these connectors?

A: Each contact is rated for 1 ampere at 30 volts maximum. Total system current capacity depends on the number of active contacts and circuit design.

Q: Why is RoHS compliance status different between the two parts?

A: The substitute part 5749084-5 is explicitly RoHS Compliant, while the main part 749084-5 lists RoHS status as not applicable. This distinction reflects manufacturing date and regulatory classification. For applications requiring RoHS compliance, 5749084-5 is the appropriate selection.

Q: Can these connectors be used in shielded applications?

A: Yes. Both parts feature shielded construction, providing electromagnetic interference protection suitable for signal integrity in sensitive applications.

Q: What termination method is used for these connectors?

A: Both parts use solder termination for through-hole mounting on printed circuit boards. The right-angle configuration positions the connector body perpendicular to the board surface.
