Key Parameters

Substitute Part Grouping Explanation

Substitution of the 749699-7 connector is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters: Connector type (Receptacle, Female Sockets), number of positions (68), contact material (Phosphor Bronze), contact finish (Gold), current rating (1A), and voltage rating (30V).

Mechanical Parameters: D-Type connector style, shell size and layout (0.050 Pitch x 0.100 Row to Row), number of rows (2), mounting type (Free Hanging In-Line), shell material and finish (Steel, Nickel Plated), and shielded feature.

Environmental Parameters: Operating temperature range (-55°C ~ 105°C), material flammability rating (UL94 V-0), and dielectric material (Thermoplastic).

Termination: IDC ribbon cable termination type.

The substitute part 5749699-7 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 5749699-7 connector is the direct substitute for the obsolete 749699-7 part number. All electrical, mechanical, and environmental specifications are identical between the two parts. The substitute part offers two significant advantages:

Product Status: The 5749699-7 is classified as Active, ensuring continued availability and supply chain support, whereas the 749699-7 is obsolete.

Regulatory Compliance: The 5749699-7 is RoHS Compliant, meeting current environmental regulations, while the 749699-7 is RoHS non-compliant. Additionally, the 5749699-7 has REACH Unaffected status compared to the main part's REACH Affected status, providing improved regulatory positioning.

For new designs, system upgrades, or replacement applications requiring a 68-position D-Type receptacle connector with IDC ribbon cable termination in the AMPLIMITE .050 III series, the 5749699-7 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 5749699-7 be used as a direct replacement for the 749699-7 in existing assemblies?

A: Yes. The 5749699-7 is electrically and mechanically identical to the 749699-7. Both connectors feature 68 positions, identical pin pitch (0.050 x 0.100), the same contact materials and finishes, and identical electrical ratings (1A at 30V). The connectors are interchangeable in applications where the 749699-7 was originally specified.

Q: What is the difference between the 749699-7 and 5749699-7 part numbers?

A: The primary differences are product status and regulatory compliance. The 749699-7 is obsolete and RoHS non-compliant, while the 5749699-7 is an active product that is RoHS Compliant. The base product number differs (749699 versus 5749699), but the functional specifications remain identical.

Q: Are there packaging differences between these two part numbers?

A: Yes. The 749699-7 packaging specification is not defined in the available data, while the 5749699-7 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What termination method is used with these connectors?

A: Both connectors use IDC (Insulation Displacement Contact) termination for ribbon cable. This termination method allows direct connection to flat ribbon cables without stripping or crimping individual wires.

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

A: Both connectors operate across the temperature range of -55°C to 105°C. This range accommodates most industrial and commercial applications. Verify that your specific application requirements fall within this operating window.

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

A: Both connectors are rated for 1A per contact at 30V maximum. Total system current capacity depends on the number of active contacts and circuit design. Ensure that individual contact current does not exceed 1A.

Q: Are these connectors shielded?

A: Yes. Both the 749699-7 and 5749699-7 feature shielded construction with a steel shell and nickel plating. The shielding provides electromagnetic interference (EMI) protection suitable for signal integrity in ribbon cable applications.
