TE Connectivity 749069-2 D-Type Receptacle Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 749069-2 is a 26-position D-Type receptacle connector with female sockets, designed for through-hole solder termination applications. This connector belongs to the AMPLIMITE .050 III series and features a shielded steel shell with nickel plating and gold-plated contacts. The part maintains active product status with 1115 pieces currently in stock.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across all critical parameters, including connector style, position count, mounting type, termination method, and environmental ratings. Alternative part numbers may be required due to inventory availability, compliance requirements, or manufacturing revisions within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 749069-2 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish substitution validity:

Critical Matching Parameters:

• Connector style (D-Type) and type (Receptacle, Female Sockets)
• Position count (26) and row configuration (2 rows)
• Shell size and pitch specifications (0.050 Pitch x 0.100 Row to Row)
• Mounting method (Through Hole) and termination type (Solder)
• Shell material and finish (Steel, Nickel Plated)
• Contact material and finish (Phosphor Bronze with Gold plating)
• Electrical ratings (1A current, 30V voltage)
• Operating temperature range (-55°C to 105°C)
• Shielded feature and flange configuration
• Dielectric material (Thermoplastic) and flammability rating (UL94 V-0)

Parts meeting all these specifications are classified as direct substitutes within the AMPLIMITE .050 III series. Variations in RoHS compliance status or REACH classification do not affect functional interchangeability but may impact procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5749069-2 is a direct functional equivalent to the 749069-2 within the AMPLIMITE .050 III connector series. Both parts maintain identical electrical and mechanical specifications across all critical parameters, including connector geometry, contact configuration, termination method, and environmental ratings.

Compliance Considerations:

The 5749069-2 carries ROHS3 compliance certification, whereas the 749069-2 is marked as not applicable for RoHS. The 5749069-2 is classified as REACH Unaffected, while the 749069-2 is REACH Affected. These compliance differences reflect manufacturing or sourcing variations but do not alter the functional performance or physical interchangeability of the connectors.

Inventory and Availability:

The 5749069-2 currently maintains higher inventory levels (1693 pieces) compared to the 749069-2 (1115 pieces), which may influence procurement decisions based on lead time and availability requirements.

Selection Basis:

Component selection between these two part numbers should be determined by project-specific compliance requirements, supply chain constraints, and regulatory obligations applicable to the end application. Both parts are active products from TE Connectivity and are suitable for through-hole solder assembly in 26-position D-Type receptacle applications operating within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Are the 749069-2 and 5749069-2 physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, shell size (0.050 Pitch x 0.100 Row to Row), mounting configuration (through-hole), and flange features. They are direct physical substitutes within the AMPLIMITE .050 III series.

Q: Do these connectors have the same electrical ratings?

A: Yes. Both parts are rated for 1A current and 30V voltage, with identical contact materials (Phosphor Bronze) and finishes (Gold plating). They operate across the same temperature range (-55°C to 105°C) and maintain equivalent signal integrity characteristics.

Q: What is the difference between the RoHS status of these two parts?

A: The 749069-2 is marked as "Not applicable" for RoHS compliance, while the 5749069-2 is ROHS3 Compliant. This distinction reflects different manufacturing batches or sourcing origins but does not affect the connector's functional performance or physical compatibility.

Q: How do the REACH classifications differ?

A: The 749069-2 is classified as REACH Affected, while the 5749069-2 is REACH Unaffected. This difference may impact procurement documentation and regulatory compliance requirements depending on the end-use application and geographic market. Consult applicable regulations for your specific application.

Q: Can I use the 5749069-2 as a replacement for the 749069-2 in existing designs?

A: Yes. The 5749069-2 is a direct functional equivalent with identical electrical and mechanical specifications. No design modifications are required for substitution. However, verify that compliance certifications (RoHS and REACH status) align with your project requirements.

Q: Are both connectors suitable for solder termination?

A: Yes. Both the 749069-2 and 5749069-2 are designed for solder termination and feature identical contact configurations and shell materials compatible with standard through-hole soldering processes.

Q: What is the packaging format for these connectors?

A: Both parts are supplied in tube packaging, which is standard for D-Type connector distribution and storage.

Q: Do these connectors provide shielding?

A: Yes. Both the 749069-2 and 5749069-2 feature shielded construction with steel shells and nickel plating, providing electromagnetic interference protection for signal integrity in 26-position D-Type applications.
