Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 749621-7 connector is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style (D-Type)
• Connector type (Plug, Male Pins)
• Number of positions (68)
• Number of rows (2)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)
• Termination method (IDC, Ribbon Cable)
• Shell material and finish (Steel, Tin-Nickel Plated)
• Contact finish (Gold)
• Current rating (1A)
• Voltage rating (30V)
• Operating temperature range (-55°C to 105°C)
• Shielded feature

The substitute part 5749621-7 maintains complete electrical and mechanical compatibility with the original 749621-7 across all specified parameters. Both connectors are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE .050 III series and support identical ribbon cable IDC termination applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (749621-7): The original 749621-7 remains suitable for applications where RoHS non-compliance is acceptable and existing supply is available. This part is active in production and maintains full electrical and mechanical specifications for 68-position D-Type plug connector applications with IDC ribbon cable termination.

Substitute Part Selection (5749621-7): The 5749621-7 is the preferred alternative when RoHS3 compliance is required for new designs or when supply chain continuity is a priority. This substitute maintains complete electrical and mechanical equivalence while offering improved regulatory compliance status. The substitute part demonstrates higher inventory availability (2100 pieces versus 877 pieces), supporting extended production runs and secondary sourcing requirements.

Both parts are manufactured by TE Connectivity AMP Connectors and are classified as Active products. Selection between these parts should be based on compliance requirements and supply availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Are the 749621-7 and 5749621-7 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shell size (0.050 Pitch x 0.100 Row to Row), mounting type (Free Hanging In-Line), and physical dimensions. They are direct mechanical substitutes.

Q: Can the 5749621-7 be used as a drop-in replacement for the 749621-7 in existing assemblies?

A: Yes. The 5749621-7 maintains complete electrical and mechanical compatibility with the 749621-7. All electrical parameters including current rating (1A), voltage rating (30V), and operating temperature range (-55°C to 105°C) are identical. The connector type, pin configuration, and IDC ribbon cable termination method are unchanged.

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

A: The primary difference is RoHS compliance status. The 749621-7 is RoHS non-compliant, while the 5749621-7 is ROHS3 compliant. All electrical and mechanical specifications remain identical.

Q: Which part should be selected for new product designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 5749621-7 is the appropriate choice. For applications without RoHS compliance requirements, either part is suitable based on availability.

Q: Are there any performance differences between these connectors?

A: No. Both connectors deliver identical electrical performance with 1A current rating, 30V voltage rating, and -55°C to 105°C operating temperature range. Contact material (Phosphor Bronze), contact finish (Gold), and shell material (Steel, Tin-Nickel Plated) are identical.

Q: What is the ribbon cable termination method for these connectors?

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

Q: Are these connectors shielded?

A: Yes. Both the 749621-7 and 5749621-7 feature shielded construction with steel shells and tin-nickel plating to provide electromagnetic interference protection.

Q: What is the moisture sensitivity level for these parts?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control requirements.
