TE Connectivity 747099-3 D-Sub Backshell Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 747099-3 is a 15-position two-piece backshell connector with 180° cable exit and shielding, designed for D-Sub applications in the AMPLIMITE series. This component functions as a protective and strain relief accessory for D-Sub connectors, featuring nickel-plated copper hardware and thermoplastic construction.

The 747099-3 carries an obsolete product status, indicating discontinuation from the manufacturer. Identification of equivalent and substitute parts is necessary to maintain design compatibility and ensure continued availability for new production builds, repairs, and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the 747099-3 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

Number of Positions: 15
Compatible Shell Size: A
Compatible D-Sub Size: 15pos and HD26pos
Cable Exit Angle: 180°
Shielding: Shielded
Cable Type: Round
Accessory Type: Two Piece Backshell
Material: Thermoplastic
Plating: Nickel over Copper
Hardware: Assembly Hardware, Strain Relief
Mating Screws: 4-40
Color: Silver

The substitute part 5747099-3 meets all these criteria and is therefore classified as a direct functional equivalent to the obsolete 747099-3.

Frequently Asked Questions (FAQ)

Q: Can the 5747099-3 be used as a direct replacement for the 747099-3?

A: Yes. The 5747099-3 is a direct functional equivalent. All critical electrical and mechanical parameters—including position count, shell size, cable exit angle, shielding, material composition, plating, and hardware specifications—are identical. The 5747099-3 will function identically in any application where the 747099-3 was originally specified.

Q: What is the difference between the 747099-3 and 5747099-3?

A: The primary differences are product status and regulatory compliance. The 747099-3 is obsolete and RoHS non-compliant, while the 5747099-3 is active and RoHS compliant. The 5747099-3 also carries REACH Affected status. Functionally and mechanically, both parts are identical.

Q: Why is the 747099-3 listed as obsolete?

A: The 747099-3 has been discontinued by TE Connectivity. The 5747099-3 represents the current active equivalent in the product line.

Q: Are there packaging differences between these parts?

A: The 5747099-3 is specified with bulk packaging. The original packaging specification for the 747099-3 was not provided in the technical data. Packaging differences do not affect functional compatibility.

Q: Is the 5747099-3 compatible with both 15-position and HD26-position D-Sub connectors?

A: Yes. The 5747099-3 is compatible with both 15pos and HD26pos D-Sub connector sizes, matching the compatibility of the 747099-3.

Q: What is the cable exit configuration for these backshells?

A: Both the 747099-3 and 5747099-3 feature a 180° cable exit angle, meaning the cable exits in the opposite direction from the connector mating face. This configuration is suitable for applications requiring straight-back cable routing.

Q: Are these parts suitable for shielded applications?

A: Yes. Both the 747099-3 and 5747099-3 are shielded backshells, providing electromagnetic shielding for the connector assembly and cable interface.
