TE Connectivity 749210-7 D-Type Receptacle Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 749210-7 is a 68-position D-type receptacle connector featuring female sockets for IDC ribbon cable termination. This connector is part of the AMPLIMITE .050 III series and is designed for applications requiring shielded signal transmission with a 0.050 pitch and 0.100 row-to-row spacing.

The 749210-7 carries an obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs, procurement, and long-term supply chain planning. Active substitute parts ensure continued availability and compliance with current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 749210-7 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector style (D-Type)
• Connector type (Receptacle, Female Sockets)
• Position count (68 positions)
• Row configuration (2 rows)
• Shell size and pitch (0.050 Pitch x 0.100 Row to Row)
• Mounting type (Free Hanging, In-Line)

Electrical Compatibility:

• Termination method (IDC, Ribbon Cable)
• Contact type (Signal)
• Current rating (1A)
• Voltage rating (30V)
• Operating temperature range (-55°C to 105°C)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)

Regulatory & Material Compliance:

• Flammability rating (UL94 V-0)
• Dielectric material (Thermoplastic)
• Series designation (AMPLIMITE .050 III)

The substitute part 5749210-7 maintains full equivalence across all mechanical, electrical, and material parameters while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

The 5749210-7 is the direct active substitute for the obsolete 749210-7. This part maintains full mechanical and electrical compatibility while offering the following advantages:

1. Product Status: The 5749210-7 carries active product status, ensuring long-term availability and continued manufacturing support from TE Connectivity.

2. Regulatory Compliance: The 5749210-7 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The original 749210-7 is RoHS non-compliant and does not meet modern procurement standards.

3. Shell Finish Difference: The 5749210-7 features a tin-plated steel shell, compared to the nickel-plated shell of the 749210-7. Both finishes provide equivalent corrosion resistance and electrical performance for this connector class and are functionally interchangeable in standard applications.

4. Packaging: The 5749210-7 is available in bulk packaging, supporting efficient procurement workflows.

For Existing Systems:

The 749210-7 remains functionally equivalent to the 5749210-7 for in-service applications where the connector is already installed. No performance degradation or compatibility issues result from the shell finish difference in established systems.

Frequently Asked Questions (FAQ)

Q: Can the 5749210-7 directly replace the 749210-7 in existing designs?

A: Yes. The 5749210-7 is mechanically and electrically identical to the 749210-7 across all critical parameters, including connector style, position count, pitch, termination method, current and voltage ratings, and operating temperature range. The connector will function identically in the same application.

Q: What is the difference between the nickel-plated and tin-plated shell finishes?

A: Both nickel plating and tin plating provide corrosion resistance and electrical conductivity suitable for D-type connectors. The choice between them is determined by application-specific environmental requirements and cost considerations. For standard signal applications, both finishes are functionally equivalent.

Q: Why is the 749210-7 listed as obsolete?

A: The 749210-7 has been superseded by the 5749210-7, which offers improved regulatory compliance (ROHS3) and active manufacturing status. TE Connectivity has transitioned production to the newer part number.

Q: Is the 5749210-7 RoHS compliant?

A: Yes. The 5749210-7 is ROHS3 compliant, meeting current environmental regulations for hazardous substance restrictions. The original 749210-7 is RoHS non-compliant.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical electrical specifications: 1A current rating, 30V voltage rating, gold contact finish, phosphor bronze contact material, and -55°C to 105°C operating temperature range.

Q: What is the pitch specification for these connectors?

A: Both connectors feature a 0.050 pitch with 0.100 row-to-row spacing, characteristic of the AMPLIMITE .050 III series. This spacing is fixed and identical between the main part and substitute.

Q: Can these connectors be used with standard IDC ribbon cable?

A: Yes. Both the 749210-7 and 5749210-7 are designed for IDC (Insulation Displacement Contact) ribbon cable termination. The termination method is identical for both parts.

Q: What is the position count and row configuration?

A: Both connectors feature 68 positions arranged in 2 rows, providing a standard D-type receptacle configuration for high-density signal applications.
