TE Connectivity 749070-7 D-Type Receptacle Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 749070-7 is a 68-position D-Type receptacle connector featuring female sockets for through-hole solder 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 contact spacing and 0.100 row-to-row configuration. The connector maintains an active product status and is manufactured with steel nickel-plated shells and gold-plated phosphor bronze contacts.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector style, position count, mounting type, termination method, shell material, contact configuration, and operating specifications. Alternative part numbers may be necessary due to inventory availability, compliance requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 749070-7 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Connector type (Receptacle, Female Sockets)
• Number of positions (68)
• Number of rows (2)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)
• Current rating (1A)
• Voltage rating (30V)
• Operating temperature range (-55°C ~ 105°C)

Mechanical Equivalence Criteria:

• Connector style (D-Type)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)
• Mounting type (Through Hole)
• Termination method (Solder)
• Shell material and finish (Steel, Nickel Plated)
• Flange feature (Housing/Shell 4-40)
• Shielded configuration

Compliance and Environmental Criteria:

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

The substitute part 5749070-7 maintains full equivalence across all electrical, mechanical, and environmental parameters, differing only in base product number designation and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 749070-7 and 5749070-7 connectors are active products manufactured by TE Connectivity AMP Connectors and maintain complete electrical and mechanical equivalence. Selection between these parts should be based on the following factors:

749070-7 (Main Part Number):

• Current inventory: 2164 pieces
• RoHS Status: Not applicable
• REACH Status: REACH Affected
• Use when REACH compliance documentation is required or when RoHS applicability is not a design constraint

5749070-7 (Substitute Part Number):

• Current inventory: 957 pieces
• RoHS Status: RoHS Compliant
• REACH Status: Vendor Undefined
• Use when RoHS compliance is a design requirement or when REACH compliance status is not a constraint

Both connectors are suitable for applications requiring 68-position D-Type receptacle connectors with solder termination, shielded configuration, and operation across the -55°C to 105°C temperature range. The choice between these parts depends on specific regulatory compliance requirements and inventory availability for the application.

Frequently Asked Questions (FAQ)

Q: Are the 749070-7 and 5749070-7 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including D-Type connector style, 68-position configuration, 0.050 pitch contact spacing, 0.100 row-to-row layout, through-hole mounting, and solder termination. They feature identical shell materials (steel, nickel-plated), contact materials (phosphor bronze with gold finish), and flange configurations (Housing/Shell 4-40).

Q: What are the electrical differences between these two part numbers?

A: There are no electrical differences. Both connectors maintain identical current ratings (1A), voltage ratings (30V), operating temperature ranges (-55°C to 105°C), and contact configurations for signal transmission.

Q: How do the RoHS and REACH compliance statuses differ?

A: The 749070-7 is marked as "Not applicable" for RoHS compliance and "REACH Affected" for REACH compliance. The 5749070-7 is marked as "RoHS Compliant" and has "Vendor Undefined" REACH status. Design teams should select the appropriate part number based on their specific regulatory requirements.

Q: Can I use these connectors in high-temperature applications?

A: Both connectors are rated for operation from -55°C to 105°C. Applications requiring operation outside this range require alternative connector designs.

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

A: Both connectors are rated for 1A per contact at 30V maximum voltage. Circuit designs must account for this current limitation when selecting wire gauges and calculating power dissipation.

Q: Are these connectors shielded?

A: Yes. Both the 749070-7 and 5749070-7 feature shielded configurations, providing electromagnetic interference protection for signal transmission.

Q: What packaging format is used for these connectors?

A: Both connectors are supplied in tube packaging, suitable for automated assembly processes and manual component handling.

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

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
