TE Connectivity 749806-2 D-Sub 15-Position Receptacle Connector

Part Overview

The TE Connectivity 749806-2 is a 15-position D-Sub receptacle connector with female sockets, designed for crimp termination in the AMPLIMITE HDP-20 series. This connector features a shielded steel shell with tin plating, gold-flashed contacts, and operates across a temperature range of -55°C to 105°C with a 250V voltage rating.

The 749806-2 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this connector configuration.

Substitute Part Grouping Explanation

Substitution of the 749806-2 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for connector style, position count, row configuration, shell size, mounting type, termination method, contact materials, and environmental ratings.

The TE Connectivity 749806-8 qualifies as a direct substitute based on the following matching parameters:

Connector style: D-Sub receptacle with female sockets
Position and row configuration: 15 positions, 2 rows
Shell size and layout: Size 2 (DA, A)
Mounting configuration: Free hanging, in-line
Termination: Crimp
Shell material and finish: Steel, tin plated
Contact finish: Gold, flash thickness
Voltage and temperature ratings: 250V, -55°C to 105°C
Flange feature: Cable side, male short screw (4-40)
Shielding: Present
Dielectric and contact materials: Polyamide nylon glass-filled, phosphor bronze
Flammability rating: UL94 V-0

The primary distinction between these parts is product status and compliance certification, not functional or mechanical compatibility.

Engineering Selection Recommendations

The 749806-8 serves as the direct functional equivalent to the obsolete 749806-2. Both connectors share identical electrical and mechanical specifications within the AMPLIMITE HDP-20 series, ensuring pin-for-pin and form-factor compatibility.

The 749806-8 is the preferred selection for new designs and ongoing production due to its active product status and RoHS compliance certification. The 749806-2, classified as obsolete and RoHS non-compliant, should be replaced in applications where regulatory compliance and long-term supply availability are required.

For applications with existing inventory of 749806-2 connectors, the 749806-8 provides a direct substitution path without requiring design modifications or re-qualification of mating interfaces.

Frequently Asked Questions (FAQ)

Q: Are the 749806-2 and 749806-8 mechanically interchangeable?

A: Yes. Both connectors share identical shell size (Size 2, DA/A layout), mounting configuration (free hanging, in-line), and flange design (cable side, male short screw 4-40). They are mechanically interchangeable in all applications.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both connectors maintain identical voltage rating (250V), operating temperature range (-55°C to 105°C), contact materials (phosphor bronze with gold flash finish), and dielectric properties (polyamide nylon, glass-filled). Electrical performance is equivalent.

Q: What is the primary reason to transition from 749806-2 to 749806-8?

A: The 749806-2 is classified as obsolete, creating supply chain risk. The 749806-8 is an active product with RoHS compliance certification, ensuring regulatory alignment and sustained availability for production and maintenance applications.

Q: Does packaging differ between these connectors?

A: The 749806-2 packaging is not specified in available documentation. The 749806-8 is supplied in bulk packaging. Confirm packaging requirements with your procurement or supply chain team.

Q: Can the 749806-8 be used as a direct replacement in existing designs?

A: Yes. The 749806-8 is a direct substitute with no design modifications required. All mechanical, electrical, and environmental specifications are identical to the 749806-2.

Q: Are there any compliance differences between these parts?

A: The 749806-2 is RoHS non-compliant. The 749806-8 is RoHS compliant. Both carry UL94 V-0 flammability certification. For applications subject to RoHS regulations, the 749806-8 is the required selection.
