Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 748952-1 is based on electrical and mechanical parameter equivalence within the D-Sub connector category. The substitute part must maintain identical specifications across the following critical parameters:

• Connector type (Plug, Male Pins)
• Position count (15 positions)
• Row configuration (2 rows)
• Shell size and layout (2 / DA, A)
• Mounting orientation (Through Hole, Right Angle)
• Termination method (Solder)
• Current and voltage ratings (6A, 125V)
• Operating temperature range (-55°C to 105°C)
• Contact finish specification (Gold, 30.0µin)
• Flange configuration (Mating Side, Female Screwlock 4-40)
• Backset spacing (0.590" / 14.99mm)

The identified substitute part maintains full compatibility with these parameters, ensuring direct functional and mechanical interchangeability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 5748952-1 be used as a direct replacement for the 748952-1 in existing assemblies?

A: Yes. The 5748952-1 is electrically and mechanically identical to the 748952-1 across all specified parameters, including pin configuration, current and voltage ratings, operating temperature range, and physical dimensions. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the significance of the RoHS compliance difference between the two parts?

A: The 748952-1 is RoHS non-compliant, while the 5748952-1 is RoHS compliant. For applications subject to RoHS directives (EU Directive 2011/65/EU and amendments), the 5748952-1 is the required choice. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: Are there any differences in contact finish or durability between these connectors?

A: No. Both parts feature identical gold contact finish at 30.0µin (0.76µm) thickness, brass contact material, and UL94 V-0 flammability rating. Durability and electrical performance characteristics are equivalent.

Q: What is the difference between the packaging formats?

A: The 748952-1 packaging is not specified in available documentation. The 5748952-1 is supplied in tray packaging, which is standard for production environments and compatible with automated assembly equipment. Tray packaging does not affect connector performance or compatibility.

Q: Are both connectors suitable for the same operating temperature range?

A: Yes. Both the 748952-1 and 5748952-1 operate across the identical temperature range of -55°C to 105°C, ensuring equivalent thermal performance in all specified environments.

Q: What is the backset spacing, and is it identical between both parts?

A: Backset spacing is 0.590" (14.99mm) for both connectors. This dimension defines the distance from the mating face to the solder tail and is critical for PCB layout compatibility. Identical backset spacing confirms mechanical interchangeability.

Q: Can the 5748952-1 handle the same current and voltage as the 748952-1?

A: Yes. Both connectors are rated for 6A current and 125V voltage, ensuring equivalent electrical performance in all specified applications.

Q: Is the 5748952-1 available in sufficient quantity for production use?

A: Yes. The 5748952-1 has confirmed inventory of 1664 pieces in stock as new original components, providing adequate supply for production and field service applications.
